Description

A backfill component for rapid construction of plastic pipes

technical field

The invention relates to the application field of pipes, in particular to a backfill component for rapid construction of plastic pipes.

Background technique

Compared with traditional pipes, such as cement pipes and metal pipes, plastic pipes have outstanding corrosion resistance, chemical stability and durability in drainage and sewage purposes. They are gradually replacing traditional pipes and are widely used in municipal Engineering, industrial construction, public buildings and other fields. However, compared with traditional rigid pipes, flexible pipes are weaker in resisting external damage, especially the brutal construction phenomenon common in pipeline construction sites; most construction sites do not have backfill materials that meet the requirements of the code, but use soil for direct backfill; the above problems Non-standard construction will have a great impact on flexible pipes, resulting in frequent pipeline safety accidents, which makes the promotion and application of plastic pipes (especially large-diameter pipes) subject to certain resistance. At present, there are no effective measures in the industry for the destruction of plastic pipelines caused by brutal construction, which leads to pipeline engineering safety accidents.

Invention patent CN106013176A reports "a method for backfilling pipe trenches in water-saving irrigation projects in mountainous areas". In the patent, the sharp stones at the bottom of the pipe trench are hammered flat, and then a single corrugated cardboard is laid. After the water pipe is placed, a piece of double corrugated cardboard is laid on the pipe, and finally backfilled and compacted. However, the protection method of this patent has little effect. The corrugated cardboard used for protection is low in strength, and it is very easy to be penetrated and damaged during the backfill compaction process, which loses the meaning of protection; Laying, but the backfilling of the pipeline is not protected on both sides, which is also prone to damage, and the actual application effect is not good.

According to relevant literature and patent reports, there are very limited measures and means for effective protection during the backfilling process of plastic pipes, but the construction protection of plastic pipes is of great significance to pipeline safety, and corresponding technical support is required.
