What is the weight of the reinforced concrete drainage pipe buried in the soil?

I. How much can the reinforced concrete drainage pipe be buried in the soil?

It is impossible to be crushed at all. Due to the concrete pipe at the center, the circular mechanical structure is very reasonable, and the force can be converted into pressure. If the impact force is not uniform, the endurance is like egg shells, which are difficult to pinch. The crushing is the same. The cement pipe is buried in a 3-meter-thick soil layer. After that, the force has now been evenly dispersed. Unless it is backfilled with stones, it will not be possible to form an uneven force. The mechanical structure of the cement pipe will be sufficient. By taking advantage of the mechanical dispersion effect, the bearing capacity can be very large, and any vehicle is basically not bad.

Second, pipe cracks often occur in the construction of reinforced concrete drainage pipes

1. Backfill if the concrete strength level does not meet the planning requirements.

2. The backfill soil was not compacted in layers according to the requirements of the code.

3. Reinforced concrete pipes have not been selected according to the planning requirements, and the grade of the pipes has been lowered without authorization. General grade pipes have been used for the second and third grade pipes.

4. Purchasers are unfamiliar with the use requirements of the pipeline, or have the thought of cutting corners and choosing pipes that are lower than the planning requirements.

The above behaviors pass on the quality problems arising from the construction and selection of pipelines below the planning requirements to the manufacturers. To this end, according to planning specifications, construction acceptance specifications, and production experience, this article is featured for reference by production, sales, and construction personnel.

3. Receptivity of reinforced concrete can be divided into written words:

1. Bending capacity. This is relatively simple, under a giant section: M = afbx (h0-x / 2) -fyAs

2. Shear capacity of inclined section

3. Bearing capacity of distorted section (also divided into tensile bending, compression bending, bending and torsional shear, bending and torsional shear bearing capacity)

4.Bearing capacity

5. Partial compression bearing capacity

There are probably so many points. What is the stress of your components? The bearing capacity of different components is different. The pressure bearing of reinforced concrete is mainly accepted by concrete, that is to say that the label of the concrete determines the bearing capacity of the column, so when the concrete label is C20, it means that the concrete specification test block 150 * 150 * 150 is 20N / mm2 during the test In terms of square meters, it is 20000KN / ㎡, and so on. C25 concrete is 25000KN / ㎡, and C35 is 35000KN / ㎡. 1KG = 10N. C20 concrete can carry a weight of 2000 tons per square meter. Of course, it needs to be slightly lower than this number, and the algorithm is somewhat expanded.

By taking advantage of the mechanical dispersion effect, the bearing capacity can be very large, and any vehicle is basically not bad. How much can a vehicle be? Over 100 tons of overloaded trucks were dead. There is a long-distance loosening project near my home. The diameter of the cement pipe used is about 1.6 meters, the thickness is about the same as what you said, and it will be repaired about 3 meters below the highway. The heavy-duty vehicle has been crushed several times, but the pipeline has been fine.

Fourth, the main use of reinforced cement pipe drainage pipe

1. Longitudinal and lateral drainage and water permeability of expressways;

2. Straight, horizontal drainage on the back and side trenches of various retaining walls of expressways; drainage pipes

3. Drainage of underground and underground tunnels;

4. Municipal works, water purification plants, sewage plants, garbage dumps and other water supply and drainage;

5. Drainage of rest oasis such as golf courses, sports fields, parks;

6. Slope soil and water conservation for hillside development;

7. Underground drainage for site preparation works;

8. Rural underground cable ducts;
