塑料檢查井有哪些功能優(yōu)勢

What are the functional advantages of plastic inspection well

塑料檢查井的功能優(yōu)勢主要有五點：

There are five main advantages of plastic inspection well

（1）耐酸堿腐蝕耐老化、使用壽命長。

(1) It is resistant to acid and alkali corrosion, aging resistance and long service life.

（2）安全環(huán)保。塑料檢查井的材料是高密度聚乙烯塑料無毒無味，使用后可回收利用。屬于化學(xué)環(huán)保建材，符合國家環(huán)境保護(hù)的大政方針。

(2) Safety and environmental protection. The material of plastic inspection well is high density polyethylene plastic, which is non-toxic and tasteless, and can be recycled after use. It belongs to chemical environmental protection building materials, in line with the national environmental protection policy.

（3）均勻沉降、抗壓。管道與井座柔性連接，管道與井座的粘土共同運動、很好的解決了傳統(tǒng)檢查井與塑料管道連接所產(chǎn)生的不均勻沉降問題，有效防止地面塌陷。

(3) Uniform settlement and compression resistance. The flexible connection between the pipeline and the well seat, the common movement of the clay between the pipeline and the well seat can well solve the uneven settlement problem caused by the connection of the traditional inspection well and the plastic pipe, and effectively prevent the ground collapse.

（4）高效排水。內(nèi)壁光滑流暢，設(shè)有導(dǎo)流槽，污物不易滯留，減少了堵塞的可能，有著出色的排水性能，雨污排放率是傳統(tǒng)檢查井的1～3倍。

(4) Efficient drainage. The inner wall is smooth and smooth, and there is a diversion channel, so the dirt is not easy to stay, which reduces the possibility of blockage. It has excellent drainage performance. The drainage rate of rainwater and sewage is 1-3 times of that of the traditional inspection well.
