塑料排水检查井是用于地下埋地管网的购筑物，安装完成后只能看到露在外面的井盖，但实际上塑料检查井在很多方面都能起到环保节能作用。
Plastic drainage inspection wells are used for the purchase of underground pipeline network. After installation, only the exposed cover can be seen. But in fact, plastic inspection wells can play an environmental protection and energy saving role in many aspects.
a.排水用塑料检查井材料上替代原来的粘土实心砖，保护了宝贵的农田资源。我国已有强制政策文件要求禁止使用粘土实心砖，但到目前为止，80%的检查井仍为砖砌检查井。
A. Plastic inspection wells are used for drainage instead of clay solid bricks to protect valuable farmland resources. There are mandatory policy documents forbidding the use of clay solid bricks in China, but up to now, 80% of the inspection wells are still brick inspection wells.
土壤也是有生命的，有专家认为土壤长厚一公分，需要花一万年的时间，保护农田资源就是保护土壤。据有关专家统计，使用塑料检查井，至少每年可保护150000亩农田。
Soil is also alive, some experts believe that the soil is one centimeter thick, it takes 10,000 years to protect farmland resources is to protect the soil. According to statistics from experts, the use of plastic inspection wells can protect at least 150000 mu of farmland annually.
b.节省宝贵的煤炭资源。排水用塑料检查井替代砖砌检查井，可以少用大量的烧制粘土砖需要的煤炭资源。保守估计，每年采用塑料检查井可节约标准煤75万吨。同时，少用煤可对大气质量净化做出贡献。
B. saves valuable coal resources. Plastic inspection wells can be used to replace brick inspection wells for drainage, which can reduce the amount of coal resources needed for firing clay bricks. Conservatively estimated that the annual use of plastic inspection wells can save 750 thousand tons of standard coal. At the same time, less coal can contribute to air quality purification.
c.保护珍贵的地下水资源，节约巨额的污水处理费用。污水管网与雨水管网通常是并列设置安放，雨水管网在污水管网的上面。砖砌排水用检查井与埋地塑料管道连接处渗漏、泄漏普遍，雨污水管网中的雨污水会渗到地下，部分雨水还会渗到污水管网。一方面污水会造成地下水资源的二次污染，另一方面加重污水处理厂的处理费用。如按减少1%渗入量计算，保守估计可节约费用5.92亿元/年。
C. protects precious groundwater resources and saves huge amounts of sewage treatment costs. Sewage pipe network and rainwater pipe network are usually arranged side by side, and the rainwater pipe network is above the sewage pipe network. The joint of brick drainage wells and buried plastic pipes leaks and leaks generally. The rain and sewage in the rain and sewage pipe network will seep underground, and some of the rain and sewage will seep into the sewage pipe network. On the one hand, sewage will cause secondary pollution of groundwater resources, on the other hand, it will aggravate the treatment costs of sewage treatment plants. If the infiltration amount is reduced by 1%, the conservative estimate can save 592 million yuan / year.
采用排水用塑料检查井，不会对地下水产生污染。
The use of plastic inspection wells for drainage will not cause pollution to groundwater.
