Construction method for additionally arranging inspection well through steel open caisson under condition of water supply and drainage pipe without water interruption
The invention discloses a construction method for additionally arranging an inspection well through a steel open caisson under the condition that water supply and drainage pipes do not cut off water, which comprises the following steps: 1, sinking construction is carried out at the position where the inspection well needs to be arranged in a non-drainage mode, and a steel horse-riding-shaped open caisson shell is pressed in; 2, after the steel horse-riding-shaped open caisson shell sinks to the designed depth, a soil body in the steel horse-riding-shaped open caisson shell is excavated, and a plurality of suspension protections arranged in the length direction of the water supply and drainage pipe are formed on the outer wall of the lower portion of the water supply and drainage pipe; 3, the soil body continues to be excavated to the bottom position of the steel horse-riding-type open caisson shell, concrete is adopted for bottom sealing construction, and a cushion layer is poured; 4, a bottom plate and a pipeline cushion block of the inspection well are constructed on the cushion layer; 5, the remaining structure of the inspection well is constructed upwards from the bottom plate, and the inspection well is connected with the water supply and drainage pipe; and 6, after all construction of the inspection well is completed, all suspension protectors and pipeline cushion blocks of the pipe are removed, and the water supply and drainage pipe is broken. The construction efficiency and safety are improved, and the stability and sealing performance of the pipeline are ensured.
本发明公开了给排水管不断水条件下通过钢沉井增设检查井的施工方法，步骤如下：1、在需要设置检查井的位置通过不排水方式下沉施工，压入钢制骑马型沉井外壳；2、在钢制骑马型沉井外壳下沉至设计深度后，开挖钢制骑马型沉井外壳内部土体，在给排水管下部外壁形成沿给排水管长度方向布置的多道悬吊保护；3、继续开挖土体至钢制骑马型沉井外壳的底部位置，采用混凝土进行封底施工，并浇筑垫层；4、在垫层上施工检查井的底板和管道垫块；5、从底板开始向上施工检查井的剩余结构，并将检查井与给排水管连接；6、完成检查井的全部施工后，拆除管所有悬吊保护和管道垫块，破除给排水管。本发明提高了施工效率和安全性，确保管道的稳定性和密封性。
