预制检查井的优势
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.
3、安全管理方面
3. Safety management
由于基坑开挖深度较深，开挖后水量大，基坑边坡不稳定，易出现塌方现象，采用现浇混凝土方法施工，施工人员在基坑内作业时间长，存在一定的安全隐患。
Due to the deep excavation depth of the foundation pit, the large amount of water after excavation, the unstable slope of the foundation pit, and prone to collapse, the cast-in-place concrete method is used for construction, and the construction personnel have a long working time in the foundation pit, which has certain safety risks.
4、经济比较方面
4. Economic comparison
从经济比较方面考虑，采用现浇混凝土方法施工，人员、材料、设备及小型机具应用较多，施工周期长，施工成本较高；如采用装配式混凝土检查井，由于构件为厂内集中预制，现场安装，既减少了人员、材料、设备等的投入，又大大缩短了施工工期，成本较现浇混凝土检查井明显降低
From the perspective of economic comparison, the cast-in-place concrete method is adopted for construction, with more application of personnel, materials, equipment and small machines and tools, long construction period and high construction cost; for example, the prefabricated concrete inspection well reduces the investment of personnel, materials and equipment, and greatly shortens the construction period due to the centralized prefabrication of components in the plant and on-site installation Concrete inspection well significantly reduced
