塑料检查井具有质轻
塑料检查井具有质轻、安装便捷、施工高效、优越的水密封性、运营费用低、使用寿命长等优点，逐步被市场与用户认知接受，尤其是在国家相关政策的引导下，塑料检查井逐步得到了很好的推广应用。表1为塑料检查井与砖砌检查井的性能对比，由此可见塑料检查井的优势。
Plastic inspection wells has the advantages of light weight, convenient installation, construction efficiency, superior water tightness, has the advantages of low cost, long service life, gradually by the market and users' cognitive acceptance, especially under the guidance of relevant state policies, plastic inspection wells have been gradually popularized very well. Table 1 is the comparison of the performance of the plastic inspection well and the brick inspection well. This shows the advantages of the plastic inspection well.

塑料检查井
Plastic inspection well
砖砌检查井
Brick inspection well
1 施工速度
1 construction speed
施工速度快，安装一座塑料井用不到1h
The construction speed is fast, and the installation of a plastic well is less than 1h
施工速度慢，砌筑一座井，包括混凝土基础及水泥养生需要1～2天
The construction speed is slow, building a well, including the concrete foundation and the cement health needs 1~2 days
2 防渗性能
2 anti-seepage performance
防渗性能佳，不会污染地下水，不会增加外来水量
Good anti-seepage performance, no pollution of groundwater, no increase of foreign water
墙体容易渗漏，塑料管与检查井的接口处底部更容易渗漏
The wall is easy to leak, and the bottom of the plastic pipe and the check well is more easy to leak at the bottom.
3 排水能力
3 drainage capacity
有水流导向的光滑大圆弧流槽，几乎没有水头损失
A smooth circular groove guide flow, almost no loss
表面粗糙，水头损失大
Rough surface, large head loss
4 井壁清洁
4 well wall cleaning
井壁清洁，不易粘结上泥垢，即使粘有泥垢也容易清除
The wall is clean, not easy to bond on dirt, even sticky dirt easily removed
井壁容易粘结泥垢，清除困难
The wall is easy to bond dirt, difficult to remove
5 连接方式
5 connection mode
柔性连接，安装速度快，密封性好，可适应少量沉降
Flexible connection, fast installation, good sealing, suitable for a small amount of settlement
刚性连接，无法承受沉降变形；沉降后会加大渗漏甚至管道破裂
Rigid connection, unable to withstand settlement deformation; after settlement, it will increase leakage or even pipe rupture.
6 耐腐蚀性
6 corrosion resistance
耐腐蚀性佳，能有效抵御酸碱废水和硫化氢气体造成的井体腐蚀
It has good corrosion resistance and can effectively resist well corrosion caused by acid base wastewater and hydrogen sulfide gas
水泥砂浆容易受酸碱腐蚀、剥落，水泥抹面剥落后渗漏愈加严重
Cement mortar is susceptible to corrosion and spalling, more serious leakage of cement plaster after spalling
7 运输损耗
7 transport loss
自重轻，便于搬运，贮运损耗低
Light self weight, easy to carry, low storage and transportation loss
所用砖块、水泥、及黄沙的重量约为塑料井的20倍，贮运损耗大
The weight of the bricks, cement and yellow sand is about 20 times that of the plastic well, and the loss of storage and transportation is great.
8 开挖土方
8 excavation of earthwork
沟槽开挖范围小，减少土方量，便于在狭小场合施工
The trench has a small excavation range, reduces the earthwork and is convenient for construction in a narrow and small situation.
沟槽开挖范围宽，土方量大，难于在狭小场合施工
The trench has a wide range of excavation and large earthwork, which is difficult to be constructed in a narrow and small situation.
9 堆料占地
9 heaps of material
无需占用堆料及拌合场地
No need to occupy the heap and the mixing site
砖块、黄沙占用堆场保定平面设计培训 防撞墙模具 防撞墙模具 防撞护栏模具 大棚遮阳网 遮阴网，水泥占用仓库，砂浆拌合还需场地
Brick, yellow sand occupied the yard, cement occupied the warehouse, mortar mixing still need field
10 文明施工
10 civilization construction
现场不再堆放砖块、砂浆。可减少施工时对周围环境和行人的影响
Bricks and mortar are no longer stacked at the site. Reduce the impact of construction on the surrounding environment and pedestrians
施工周期长，现场堆放砖块、砂浆。影响周围环境和行人通行
The construction period is long, and the bricks and mortar are stacked at the site. Influence the surrounding environment and pedestrian passage
