社会的进步发展，我国进入城市现代化的发展，同时对于城市道路的质量要求越来越高，在城市道路的病害当中，检查井的品质及要求下降越来越明显，现在的车辆对道路的超负荷影响，检查井沉降后都道路的破坏严重影响着车辆的正常通行，塑料检查井相对起来检查井而言环保节能，安装方便，节约成本等特点受到消费者的喜爱，尤其是钢骨架塑料检查井：
With the progress and development of society, China has entered into the development of urban modernization. At the same time, the quality requirements of urban roads are getting higher and higher. Among the diseases of urban roads, the quality and requirements of inspection wells are declining more and more obviously. The impact of vehicles on road overload is now obvious. The damage of roads after the settlement of inspection wells seriously affects the normal traffic of vehicles. Plastic inspection wells are relative. As far as inspection wells are concerned, they are environmentally friendly, energy-saving, easy to install and cost-saving, etc. They are popular with consumers, especially for steel-framed plastic inspection wells.
钢骨架塑料检查井克服了普通塑料检查井的荷载值低的问题，因为钢，塑两种材料的完美结合，极大提高塑料检查井的荷载能力，钢骨架塑料检查井重量轻，安装方便，耐腐蚀，耐高温，结构优良，且内壁光滑不易堵塞等特点。
Steel skeleton plastic inspection well overcomes the problem of low load value of ordinary plastic inspection well, because the perfect combination of steel and plastic materials greatly improves the load capacity of plastic inspection well. Steel skeleton plastic inspection well has the characteristics of light weight, convenient installation, corrosion resistance, high temperature resistance, excellent structure, smooth inner wall and not easy to plug.
塑料检查井的排水性能好坏关系到检查进的密封问题，同时也是城市排水管工程验收的关键所在，检查井与管道的接口处容易出现泄露的情况，分为井筒接管承口密封，井筒承口密封两类。
The drainage performance of plastic inspection wells is not only related to the sealing problem of inspection, but also the key to the acceptance of urban drainage pipe engineering. The leakage at the interface between inspection wells and pipelines is easy to occur, which can be divided into two categories: wellbore nozzle socket seal and wellbore socket seal.
检查井的密封方式有很多，市面上常见的是密封方法有橡胶圈密封和热收缩密封。
There are many sealing methods for inspection wells. The common sealing methods on the market are rubber ring seal and heat shrinkage seal.
