预制检查井的优势
Advantages of prefabricated inspection well
1、质量及进度控制
1. Quality and progress control
装配式混凝土检查井与传统现浇混凝土井相比，具有现场施工简易快捷，井室稳定性、密封性、耐久性、环保性好的特点，质量易控、工艺更先进，施工工期短的特点。
Compared with the traditional cast-in-place concrete inspection well, the fabricated concrete inspection well has the characteristics of simple and fast on-site construction, good stability, sealing, durability and environmental protection of the well chamber, easy quality control, more advanced technology and short construction period.
2、现场实际施工条件及工期
2. Actual site construction conditions and construction period
由于管网工程绝大部分位于水田中，地下水位较高，基坑开挖后水量较大，降水时间长，不利于现浇混凝土施工。又临时征地原因，住建局要求在耕种前结束占用农民耕地的施工段，现场工期十分紧迫，住建局多次催促工期，加快施工进度，因现场实际地勘情况，现浇混凝土检查井施工时间长，施工质量与进度无法把控。
Because most of the pipe network works are located in the water field, the underground water level is high, the water volume after the excavation of the foundation pit is large, and the precipitation time is long, which is not conducive to the cast-in-place concrete construction. As for the reason of temporary land acquisition, the Bureau of housing and urban rural development requires that the construction section occupying farmers' cultivated land should be completed before farming. The construction period is very urgent. The Bureau of housing and urban rural development urges the construction period for many times to speed up the construction progress. Due to the actual geological survey on site, the construction time of cast-in-place concrete inspection well is long, and the construction quality and progress cannot be controlled.
