What is the quota of circular pipe culvert?

Question 1: How does the highway engineering quota project apply to reinforced concrete circular culvert? Please give us your suggestions. There are about seven or eight places to be decided. First, the prefabrication quota and installation quota of circular pipe culvert are applied according to the pipe diameter, and the reinforcement quota is applied according to the number of steel bars; Then, according to the designed circular pipe culvert foundation, the circular pipe culvert foundation quota is applied; Apply for excavation quota according to the situation of foundation pit; The quota of retaining wall foundation and wall body shall be applied according to the number of wall bodies and foundations of "8" shaped walls or "1" shaped walls; According to the number of cap stones in the circular pipe culvert in the drawing, the cap stone prefabrication and cap stone installation quota in the small component prefabrication quota are applied; Apply cutoff wall quota according to the number of cutoff walls in the drawings; The paving quota shall be applied according to the paving quantity in the drawings.

Question 2: What quotas should be applied to reinforced concrete circular culvert? It depends on the project. When it appears in any project, it should be applied according to the design requirements.

Question 4: What quotas should be applied to reinforced concrete circular pipe culvert with a single hole diameter of 80? Municipal or highway?

Question 5: What is the casing quota of cement culvert? 10 set of concrete circular pipe culvert.

Question 6: How to calculate the quantity of circular pipe culvert 1? If the project budget is calculated, it shall be calculated according to the highway project budget quota. The project contents include: foundation excavation, foundation cushion, foundation concrete, prefabricated circular pipe culvert, circular pipe installation, culvert concrete mixing, end wall masonry, asphalt wadding filling, waterproof coating, eight walls masonry and paving (mortar rubble), etc.

2. Measurement: First look at the list requirements in the construction contract and related contract documents. Generally, the measurement is based on the length of circular pipe culvert.

Question 7: How to do the budget of engineering cement circular culvert? 5 points can be multiplied by the corresponding coefficient in the quota, or can be converted according to the quota, and the exchange price is subtracted from the exchange price. The constant engineering quantity is only the change of price.

Question 8: Many people have been looking for a formula to change the lunar calendar. I tried, too. I have read the Academic Thesis written by senior astronomers, and learned about the changes of ancient calendars and the defects of Yin and Yang calendars. Only then did I know that there was no formula to find because of the instability and irregularity of the moon's rotation. This is also the reason why China had to change its calendar every hundred years in ancient times. The biggest problem in the lunar calendar is how to set a leap year. It doesn't seem difficult, because the basic rules of the lunar calendar are as follows:

* The first day of every month is the first day.

* Month is named after Zhongqi.

* The first month is a "cloudy" month.

* leap month is a lifeless month, and the previous month has the same name.

If the rotation of the sun and the moon is regular, it is not difficult to derive a set of formulas for the conversion of yin and yang calendars. The problem is that sometimes the lunar month is longer than the solar month. Such a lunar month may contain two neutral gases. The names of lunar months after this double neutral month are all messy, and will not be adjusted until the next "fake" leap month.

Most people come into contact with the lunar calendar, which is a civil calendar, published by * * *, and calculated by East longitude 120 degrees, or Central Plains standard time, or Beijing time. If we recalculate the Yin-Yang calendar with different time zones and different longitudes, there will be a big problem with the leap rule of the civil calendar. Leap months in different time zones may fall in different months. In other words, in one hundred years, the leap month sequence pattern of any two time zones will be different.

Gao's predecessors mentioned the leap calendar. If the leap method is applied to different time zones, all leap months in different time zones are in the same month. In this way, the leap problem of yin-yang calendars with different time zones and longitudes disappears. The difference between civil leap calendar and leap calendar lies in:

* leap in civil use, if the new moon is on the same day as qi, then the lunar month contains that qi.

* leap in the calendar, if the date of the new moon and the date of the new moon are on the same day, and the date of the new moon must be before the date of the new moon, then the lunar month includes the new moon.

In short, the folk comparison between new moon and neutral day; Compare the date, hour, minute and second of the new moon and gas in the calendar. Therefore, if there are no accurate time figures of the sun and the moon, the leap month of the lunar calendar may be arranged incorrectly.

For these reasons, I began to look for astronomical formulas to calculate the exact time of the sun and the moon in latitude. When there was no internet, I spent half a year looking for answers in major libraries and universities in southern California. 1993 published the book "Sino-American Astronomical Calendar". The exact astronomical date, month and time in the book are only between 1900 and 20 10 years. I'm afraid the time error after 20 1 1 is more than one minute, which is not accurate enough to print. In 2002, after I determined the accuracy of the sun and moon time from the network information, I rearranged the information in my busy schedule and provided it to friends who needed the lunar conversion formula.

The time numbers of the sun and the moon range from 1 to 2246. There are calendars and China civil calendars. Digital content clearly shows the end of the civil calendar. For example, from 1600 to 2246, the folk calendar has 22 lunar months and only 5 calendar months. Even in 2033, February128, 2242, the civil calendar actually used up two pairs of gas in three months; In other words, there are two "fake" leap months in three months. 12 There are three leap months in the lunar calendar, and the issue of whether or not to stay in the leap months has aroused many scholars' discussions and concerns. During these three years, the calendar did not find a double lunar month. As long as the "fake" leap month after the double neutral month is cancelled, the calendar will be almost perfect.

Therefore, the civil calendar is very problematic and should be abolished. The last big change of the lunar calendar was in 1645, which has been more than 350 years. With the progress of astronomical science, the lunar calendar in China should use a more accurate calendar. So that future generations will not waste time discussing whether to stay or not.

Yin and Yang calendars are mostly used for eight-character fortune-telling, Wei Zi Dou Shu, peasant calendar and Tibetan calendar. Many people don't know that the horoscope only uses the solar calendar, not the lunar calendar. I spent a lot of time studying the conversion of the lunar calendar. In fact, the eight characters are only solar terms used by the sun, and have nothing to do with the moon. Wei Zi needs the date of the lunar calendar to arrange his horoscope. Half of the lunar calendar dates in the American time zone are one day different from those in China, because the time difference is more than 12 hours; The first day may be a different day. A friend, a professional fortune teller in Canada, is proficient in eight-character and purple-micro-bucket numbers and studies her own female chart. Parents' eight-character theory is reasonable. Counting my parents' palaces, I can't see my own shadow. Later, I found the answer to "one day short" in the book "Sino-American Astronomical Calendar".

There was once a retired doctor who spent nearly 30 years looking for the formula of the lunar calendar and asked twice ... >>
