| 管道检查井砌筑方法： Masonry method of pipeline inspection well: A、井坑与基础 A. Pit and foundation 1、井坑应与管沟同时开挖，开挖时井座主管线应与管沟中管道在同一轴线。井坑边坡与管沟边坡一致。井坑开挖时，不得扰动基土超挖;如基土受到扰动，则应按现行的《给排水管道工程施工及验收规范》GB 50268的有关规定，根据基土土质采取补救措施。有沉泥室雨水检查井井坑，应根据选用的规格，局部开挖沉泥室深度。井坑开挖应根据选用的规格，考虑井座主管线偏置因素，偏置端得坑壁应与管沟齐平。 1. The well pit shall be excavated at the same time with the pipe trench, and the main line of the well seat shall be in the same axis with the pipe in the pipe trench. The pit slope is consistent with the pipe trench slope. During pit excavation, the over excavation of foundation soil shall not be disturbed; if the foundation soil is disturbed, remedial measures shall be taken according to the current code for construction and acceptance of water supply and drainage pipeline engineering (GB 50268). If there is a mud chamber for rainwater inspection, the depth of the mud chamber shall be excavated locally according to the selected specifications. According to the selected specifications and considering the offset factor of the main line of the well base, the pit wall at the offset end shall be flush with the pipe trench. 2、地下水位较高的地区或雨季施工，应有排水，降低水位措施。 2. In areas with high groundwater level or construction in rainy season, drainage and water level reduction measures shall be taken. 3、检查井基础应根据当地地质勘察和回填土下拽力经计算确定。当无时，可按检查井基础图施工。B、检查井接管安装1、检查井井座与管道连接安装顺序，应先从接户管上游段开始安装，以井-管-井-管顺序安装，病逐渐向下游支管，干管延伸。 3. The foundation of inspection well shall be determined by calculation according to the local geological survey and the pulling force under the backfill. If not, construction can be carried out according to the foundation drawing of inspection well. B. Installation of inspection well connecting pipe 1. The installation sequence of inspection well base and pipeline connection should start from the upstream section of the connecting pipe, and install in the sequence of well pipe well pipe. The fault gradually extends to the downstream branch pipe and main pipe. |
