| 检查井五种施工工法有如下优缺点： Five construction methods of inspection wells have the following advantages and disadvantages: 1、传统砖砌检查井：需要人工砌筑，质量取决于工人技术水平。劳动生产率低下，不利于管道装配化快速施工，影响城市交通。强度低、使用一段时间后表皮脱落内里疏松，造成检查井整体下沉，周边路面沉降，成为道路工程中的一大通病。透水性高，污染地下水资源。粘土烧结，破坏耕地。 1. Traditional brick inspection wells: need to be manually built, the quality depends on the technical level of workers. Low labor productivity is not conducive to rapid pipeline assembly construction, affecting urban traffic. Low strength and loose inner skin after using for a period of time cause the overall subsidence of inspection wells and the settlement of surrounding pavement, which has become a common problem in road engineering. High permeability and pollution of groundwater resources. Clay sintering destroys farmland. 2、现浇混凝土检查井：现场模板支护，开挖断面大，扰动现状土范围大。异型检查井支护模板难度大。养护时间长。总体造价高。 2. Cast-in-situ concrete inspection wells: on-site formwork support, large excavation section, large disturbance current soil range. The support formwork of special-shaped inspection wells is very difficult. Maintenance time is long. The overall cost is high. |
