How to improve the engineering quality of fine gardens.

What is the specific content of how to improve the quality of fine garden projects? Zhong Da Consulting will answer your questions below.

Professor Sandholm, a world-renowned management expert, said: "Quality is the golden key to open the world market". High-quality products and services are effective means to participate in market competition and the fundamental guarantee to win users, occupy the market and develop themselves.

With the rapid development of landscaping enterprises today, landscape engineering is also facing higher quality requirements. Conventional methods, such as technical specifications and standards, equipment assurance and inspection methods, sometimes cannot meet the potential demand for higher engineering quality. Pay attention to quality management in many ways, and the landscape engineering will get better and better.

First, actively communicate with the design to avoid design defects in the project.

Every time you accept a new construction task, it is essential to actively communicate with the owners and designers. Only by deeply understanding the design concept of the project can we create a good landscape effect. We exchanged views with the designer on the differences in the construction drawing. In some engineering projects, designers often design super-large tree species as the focus of landscape, but this often fails to achieve the expected effect of designers. Due to the poor regeneration ability during the planting process, extra-large trees will even shrink after planting, and the landscape effect is not good; Sometimes, in order to improve the survival rate, strong pruning will inevitably destroy the original posture of the trees themselves, and the posture after planting is not satisfactory. Once acclimatization and mismanagement lead to the death of trees, precious natural resources will be wasted. If this happens, we will suggest that the designer should choose a middle-aged robust tree with DBH of 15-20 cm. This kind of trees are in the vigorous growth period, which not only has little impact on their harm, but also the trees themselves recover quickly and survive easily, so this phenomenon will not occur.

Sometimes designers ignore the biological characteristics and ecological habits of plants because they pursue the formal beauty of the landscape too much. Formal beauty and ecological beauty are not well combined, such as planting trees that like light but are not cold-resistant on the north side of the building; Plants that are not hardy are planted in ventilated places between buildings. Under this site condition, plants are not growing well and can't bloom and make scenery. Sometimes only the recent results are considered in the collocation of plant species, such as the architectural foundation planting. Plant species planted near the corner grow slower than those planted at the outer edge. After a year or two, the outer edge covered the one near the corner, and the original layered design concept could not be realized.

Second, careful construction, try our best to improve the engineering design and create the artistry of the project.

As a construction enterprise, we believe that the role of construction personnel in completing a successful landscape engineering work can not be ignored. Construction workers need literary skills, artistic vision and professional standards in order to combine the positioning, posture, orientation, size and species of plants in the multi-dimensional space landscape that is difficult to describe on the drawings, and create the best engineering works through our understanding, cooperation and adjustment.

Although it is made by people, it is natural, which is the highest artistic realm of garden works. For this goal, we have been trying to explore how to improve the works in the construction process, paying attention to the combination of artistic beauty and natural beauty, and the unity of formal beauty and ecological beauty.

Because the main plant material is different from other materials in construction engineering, it is a living and vital material. The same plant variety has its own characteristics, but there are still individual differences. For example, when three trees are planted in groups, the DBH and crown width are the same, but the fullness and height of posture are inconsistent. Construction personnel should give full play to their subjective initiative, adjust measures to local conditions and combine the three factories. The plump posture is in the main viewing position, low in the front and high in the back, which makes up for the individual posture defects in the combined position and achieves the best plant landscape effect.

The content of landscape engineering extends to the combination of various landscape elements, except plants, such as pavement, garden road, tables and chairs, pools, flower racks, etc. are all civil works; However, because landscape engineering is a job that gives people visual pleasure as the primary condition and meets other functional requirements, the requirements for civil engineering are higher. For example, the closure of the road surface is not ugly on the drawings, but it will not look good after the work is made. Adjust the layout slightly according to the actual effect when paying off, which will not affect the overall layout and use function, and the aesthetic problem will be solved.

Third, respect science, overcome technical difficulties, and provide technical support for landscape engineering.

In the construction, we will constantly face new technical problems to be solved and overcome, which requires us to have the spirit of respecting science and seeking truth from facts, actively overcome construction difficulties and successfully complete the construction. Soil is the foundation of our garden engineering construction, and the quality of soil directly affects the survival rate and future growth potential of seedlings.

This problem has been encountered in the construction of Tianyuan Riverside Park 1 2 plots. After the earthwork is partially constructed according to the design and specification requirements, it is found that there is brown pulp flooding, and the pH value is as high as 1 1, which is not a construction problem that can be solved by satisfying earthwork modeling and soil thickness. Because the former site of the park is Tianyuan chemical plant, the soil pollution is serious, and a single earthwork model can not solve the soil pollution problem. Based on this, we discussed with the design and construction units and suggested that the original earthwork construction scheme should be adjusted from two aspects. On the one hand, we added an isolation pad in the planting area, that is, the original cement floor will not be transported out after being broken, but will be kept as an isolation layer, covered with stones with a thickness of 20 cm and a diameter of 3-5 cm, and then covered with non-woven fabrics to prevent the polluted underground mud from flowing back into the planting soil to be polluted again. On the other hand, we appropriately increase the thickness of the soil layer to improve the terrain elevation, that is, the distance between the seedling roots and the polluted soil. Practice has proved that the construction scheme is operable, and the completed park seedlings grow healthily and the plant landscape effect is excellent. This project won the title of Shanghai Garden Cup Quality Project in 2004.

In the greening project construction of Jinshan Chemical Industry Zone, the high salinization of soil is a technical problem. We have taken the following improvement measures: first, combining with the terrain, improving soil and discharging salt, raising the ground elevation appropriately and creating undulating terrain can reduce the relative groundwater level and reduce the harm of soil returning salt to seedlings; After precipitation leaching, the soil salt content decreased; Dig out the surface 30-40cm saline soil, and backfill the planting soil and nutrient soil containing organic fertilizer to the design elevation, so as to provide good soil conditions for plant growth. Second, dig ditches to drain salt; For the accumulated salt located 30-40 cm below the surface, measures such as pipeline, blind ditch and natural drainage should be taken according to local conditions during construction, and natural rainwater leaching or artificial irrigation should be used to promote soil desalination. Thirdly, the combination of biological improvement engineering and biotechnology measures is an effective way to improve saline soil. Biological improvement generally grows alfalfa or leguminous crops, with rhizobia, which plays a certain role in improving soil and improving soil fertility. Fourth, cover the salt; Plant straw and other materials cover the soil surface, plant legumes, and increase the planting density of green space, which can reduce direct sunlight and groundwater evaporation, effectively inhibit soil salt return, and improve the survival rate of newly planted trees. Through the above technical measures, initial results have been achieved. After one year, the survival rate of seedlings was as high as 95%, and the salinization gradually decreased.

Fourth, pay attention to details, be good at detail construction, and reflect engineering precision from nuances.

Details determine success or failure. This is especially true for the details of excellent works.

The supporting, fixing, binding and winding of tree altar and column are auxiliary works in this project. If these auxiliary projects are not carefully constructed and shoddy, the texture of the whole project will be greatly reduced and the quality of the project will be affected in detail. And attention to detail will give a complete decoration to the landscape effect of the whole project.

In completed projects, we often see untreated tree holes. The common rough tree altar is the original "wine-brewed tan", and the loess is exposed. Two people threw tall steamed buns, which were incompatible with the surrounding terrain and always felt that it was the failure of the whole project. Our treatment: retaining the original "wine-brewed tan" is conducive to the maintenance and management of the lawn next to the cave. Loess is covered with bark, ceramsite, etc. Or planting ground cover plants such as Ophiopogon japonicus and Ivy, which not only prevents dust from flying, but also is beautiful. If it is really necessary to raise the planting height of trees because of the high groundwater level, the terrain around the tree hole can be raised appropriately, so that the tree hole has a good transition with the surrounding terrain and the whole is harmonious and beautiful.

Supporting, fixing, binding and other projects are considered as the simplest auxiliary work, often because we don't care about or ignore it at ordinary times, which will greatly reduce the quality of the whole project. Support materials should be uniform, the thickness and length of bamboo strips or wooden strips should be consistent, and the support can be polished and painted if conditions permit; When binding, the support should be horizontal and vertical, the crossbar should be kept at the same height as the ground, the trunk should be vertical to the ground, the diagonal should be at the same angle as the ground, and the trunk should be padded to protect the bark from damage; The winding rod starts from the soil surface of the trunk to the first or second bifurcation point, and the whole tree is naturally connected without breaking or overlapping of straw rope or linen. The concise and exquisite details are refreshing and complement the whole work.

In the construction of street trees, a large number of street trees meet the requirements of the code, some have slightly curved trunks and some have slightly lower bifurcation points. When planting, we unify the bent edge of the trunk with the arrangement of trees, and arrange them from high to low or from low to high according to the bifurcation points of the trunk, so that the irregular personality characteristics of street trees are unified in the regular layout, which makes up for the differences in personality characteristics of trees in details.

In garden civil engineering, there are also many construction details that need to be paid attention to: the jointing materials for surface paving must be of the same origin, batch number and specification as the pasting materials, the proportion of fine sand cement slurry is 1: 1, the joint surface is 3 mm concave and dense, and the jointing appearance is soft and smooth; When building a winding garden road, we should pay attention to the natural smoothness of the curved S-shaped bend of the garden road. Ensure that the formwork is firmly supported without obvious bending, and the poured concrete kerb is not uneven. Pebble paving: Brush the 1: 0.4- 1: 0.5 plain cement slurry bonding layer on the wet base, wipe the leveling layer with 1: 3 hard cement slurry while brushing, flatten it with an iron trowel, then spread pebbles, compact and flatten it with a wooden trowel, dry the cement and spray it with a sprayer. On the second day after construction, it should be covered with protective film for adequate water conservation.
