The length of the reinforced concrete pipe entering the inspection well depends on the specific situation, and there are some common regulations that need to be followed.

1.Straight pipeline: The distance from the entrance of the straight pipeline to the top edge of the inspection well (that is, the center distance) should not exceed 15m, and when the length exceeds 15m, an intermediate inspection well should be set.

2.The pipe section where the interface accessories such as elbows and T-shaped pipes are located: the distance between this kind of pipe fittings and the center of the inspection well should not exceed 10m.

3.Horizontal pipeline or pipe section: When this type of pipeline enters the inspection well, the pipeline should extend to the bottom of the inspection well.

It should be noted that these regulations may vary due to factors such as laws and regulations, engineering standards and architectural engineering design in different countries or regions, so in specific use, it is necessary to follow local standards and engineering design requirements.

Under the given conditions, the length of the reinforced water mud pipe into the inspection shaft depends on the following factors: the depth of the inspection well, the buried depth of the pipeline and the height of the ground, etc. If the buried depth of the pipeline is deep and the depth of the inspection well is shallow, the length of entering the inspection well is relatively short; Conversely, if the buried depth of the pipeline is shallow and the depth of the inspection well is deep, the length into the inspection well is relatively long.

In addition, it is also necessary to consider factors such as the bending of the pipeline, the direction of the horizontal and vertical directions, etc., to ensure that the length of the pipeline entering the inspection well meets the design requirements. Therefore, the specific length needs to be evaluated and determined according to the actual situation.

The trillion-length of the reinforced concrete pipe entering the inspection well should be designed according to the need, and it is usually necessary to ensure that there is still a certain stretch room after the pipeline enters the inspection well, so as to facilitate the free expansion and contraction of the pipeline and avoid problems such as pipeline rupture caused by insufficient degree of freedom of the pipeline. Therefore, the degree of freedom and scalability of the pipeline should be taken into account in the design. In addition, the reinforced cement pipe needs to be strictly measured and cut before entering the inspection orange rock well to ensure that the pipe length is just suitable for the depth of the inspection well, so as to ensure the effective use and stability of the pipeline.

It is important to note that longer pipe lengths, while providing greater freedom and scalability, can also increase cost and engineering difficulty. Therefore, it is necessary to comprehensively consider all factors in the design, balance the needs and constraints of various ethnic groups, and design with the optimal solution.

The amount of reinforcement, the main thing is that you have to learn how to calculate is the most important, many netizens ask this question in the know, the calculation is relatively troublesome, and no one can spend a lot of time to calculate it specifically, but you can calculate it yourself if you understand the algorithm, and the diameter and length of the steel bar you want to calculate are indicated on the diagram.

I will send you a formula: the diameter of the steel bar (mm) the diameter of the steel bar (mm) The weight of the steel bar per meter (kg) is an example according to the steel bar in Figure 12 you sent:

I don't know what the difference between you are referring to bai?

1. The first material is different. Brickwork zhi

Rainwater inspection wells are mainly made of clay bricks or shale bricks. Concrete rainwater inspection wells are generally divided into reinforced concrete inspection wells and precast concrete modules.

2. The cost is different. Brick rainwater inspection wells are the cheapest; Precast concrete modules are more expensive; Reinforced concrete inspection wells are the most expensive.

3. I think you may be asking about the use, the brick inspection well is covered with soil less than 4 meters in accordance with the requirements of the national standard, and the pipe diameter is less than d2200mm. The same is true for precast concrete modules. The special forms of inspection wells such as large pipe diameter, large buried depth and double row should be considered to use reinforced concrete.

Not sure if these are what you want to know.
