Plastic inspection well is a subsidiary structure that connects rain, sewage discharge plastic pipes, and supplies support workers or equipment to check and remove foreign objects. It is very convenient for automatic or semi automated periodic inspection and dredging. It is a environmental pollution pipe system with good circulation performance, strong sealing, long service life, convenient construction and installation, and land saving and land saving with plastic pipes and fittings. The plastic inspection wells are made of polymer resin plastics and combined structure and typical structure. It is usually made up of well, wellbore, well cover, cover and concrete support board, such as the necessary variable diameter joint, variable angle joint and sealing ring.

它具有如下特点：

It has the following characteristics:

1） 所采用的塑料为热塑性塑料,加工耗能低,同时环保节能、耐腐蚀、使用寿命长。

1) the plastic used is thermoplastic, with low energy consumption and environmental protection, energy saving, corrosion resistance and long service life.

2） 塑料检查井采用工厂化生产,产品尺寸精确,质量稳定,生产周期快且制作过程不受现场条件如气候、地质的影响。

2) the plastic inspection well adopts the factory production, the product size is accurate, the quality is stable, the production cycle is fast and the production process is not affected by the conditions of the field, such as climate and geology.

3） 塑料检查井与塑料排水管道使用相同的塑料材质,相同的井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具 基础形式，相同的接口形式,可以有效地解决管道与井的连接问题。

3) plastic inspection well and plastic drainage pipe use the same plastic material, the same basic form, the same form of interface, can effectively solve the connection between the pipe and the well.

4） 可采用弹性密封圈连接或胶粘剂粘接,避免了不均匀沉降对管道造成的破坏,大大提高了管道和井的抗渗性、密封性,有利于排水管道长期安全使用,也避免了地下水的二次污染,安全环保。

4) the elastic sealing ring or adhesive bonding can be used to avoid the damage caused by the uneven settlement to the pipeline, greatly improve the permeability and sealing of the pipes and wells, be beneficial to the long-term safe use of the drainage pipes, and avoid the two pollution of the groundwater, and the safety and environmental protection.
