Compared with our present day, the cement pipe is like the water resources we usually use, which is closely related to our day. As an ancient city, it is still relatively developed. Various corporate cultures are being carried out. In our industrial construction projects, cement pipes are a very important part of the building materials. They have a wide variety and rich styles. Reinforced concrete drainage pipe is also one of the ways. Today, the main editor of the cement pipe manufacturer mainly talks about the skills of the reinforced concrete drainage pipe to avoid the impact of backfilling.

A lot of water in the trench and the collapse of the trench. Above-ground engineering construction usually catches up with the dry season, because the construction site is low-lying, and after the trench is excavated, there is a large amount of water, which can reach more than 1.0m in deep areas. Because the high-pressure reinforced concrete drainage pipe is light in weight, after the pipe is installed in the ditch, it fully floats on the water. Because of the buoyancy of water, it is difficult to press the glass reinforced concrete drainage pipe into the bottom of the trench with soil during backfilling, which causes the buried depth of the pipeline to fail to meet the design requirements.

Because there is too much water in the ditch, it is difficult to grasp the flatness of the ditch bottom, and it is difficult to see whether there are hard objects such as pipelines and broken stones at the bottom of the ditch, and it is difficult to ensure the construction quality of the reinforced concrete drainage pipe. The accumulation of water in the pipe trench in the low-lying area simply causes the pipe trench to collapse, and the massive earthwork that collapses will often directly hit the reinforced concrete drainage pipe and smash the pipe.

Impact force of hard objects such as stones and mechanical backfill in the trench trench backfill. The backfill soil in low-lying areas is relatively wet, and even some of them are basically in the state of mud. During the backfill process, if the mud is mixed with hard objects such as stones, it is difficult to find. These stones are buried in the bottom of the ditch directly with reinforced concrete. Drain pipe contact will cause great damage to the pipeline.

It is also possible that during the backfilling process, because of the large stones, the reinforced concrete drainage pipe was directly damaged under the impact of gravity. During mechanical backfilling, the soil from the full bucket is backfilled directly into the trench from a high place, and the pipeline will be damaged due to the large impact force. The construction personnel did not operate in accordance with the specifications. For example, when the pipeline was connected, the muddy water in the threaded part was not wiped clean, the screwing depth was not enough, and water, mud and other debris in the pipeline.

So no matter what product equipment you want to use better, the first skill is an indispensable part. The skills we often say are the driving force behind our progress, and it is this principle.
