Pipeline foundation trench construction method
The invention relates to the technical field of underground pipeline construction, and provides a pipeline foundation trench construction method which comprises the following steps: constructing a support pile and a jet grouting pile waterproof curtain in a soil body between a river channel and a river adjacent section of a foundation trench; a water retaining dam is constructed on the river channel to divide the river channel into an upstream section, a midstream section and a downstream section, and the river passing section of the foundation trench is located in the midstream section; permanent steel sheet piles are constructed at the bottoms of the riverbeds on the two sides of the river passing section; digging soil bodies in the river-near section and the river-crossing section of the foundation trench to a target depth to form the foundation trench; a dewatering well is constructed at the bottom of the foundation trench; and anti-floating anchor rods and prefabricated supporting wrapping pieces are constructed at the bottom of the river passing section of the foundation trench. The anti-floating anchor rods are constructed at the bottom of the river crossing section, the anti-floating anchor rods are connected with the prefabricated supporting wrapping pieces wrapping the pipeline, the bottom of the river crossing section of the foundation trench is solidified while the pipeline is fixed, and floating deformation of the pipeline and the foundation trench can be effectively prevented.
本申请涉及地下管线施工技术领域，提供了一种管道基槽施工方法，包括以下步骤：在河道与基槽的临河段之间的土体中施工支护桩和旋喷桩止水帷幕；在河道上施工出挡水坝，以将河道分隔为上游段、中游段和下游段，基槽的过河段位于中游段内；在过河段的两侧的河床底部，施工出永久钢板桩；挖出基槽的临河段和过河段内的土体至目标深度，形成基槽；在基槽的底部施工降水井；在基槽的过河段的底部施工抗浮锚杆和预制支撑包裹件。本发明通过在过河段的底部施工抗浮锚杆，利用抗浮锚杆与包裹管道的预制支撑包裹件连接，使管道被固定的同时，固化了基槽的过河段的底部，可有效预防管道和基槽的上浮变形。
