Post construction method for settlement rod of underground concealed pipeline
The invention discloses a post construction method for a settlement rod of an underground concealed pipeline. According to the method, a guide hole is drilled to form a mounting hole, then a wall protection sleeve and the settlement rod are put down to avoid large-area excavation of earthwork at a settlement monitoring point, the wall protection sleeve is used for protecting the settlement rod, and the settlement rod is fixedly connected to the underground concealed pipeline through a consolidation body, so that the settlement rod moves up and down along with the deformation of the underground concealed pipeline and is not influenced by surrounding soil, the settlement rod and the underground concealed pipeline are connected into a whole through the consolidation body, the settlement rod moves up and down along with the deformation of the pipeline, and the accurate settlement value of the monitored underground concealed pipeline can be obtained by observing the settlement value of the top end of the settlement rod. According to the method, the problems that earth excavation conditions do not exist above the underground concealed pipeline, and due to the fact that the space is limited or the pipeline protection requirement is high, settlement monitoring of the underground concealed pipeline cannot be carried out through direct monitoring point method construction are solved.
本发明公开了一种地下暗敷管线的沉降杆后置施工方法，通过钻进引孔形成安装孔进而下放护壁套管和沉降杆以避免大面积开挖沉降监测点的土方，护壁套管用于保护沉降杆，沉降杆通过固结体固定连接于地下暗敷管线，使沉降杆随着地下暗敷管线的变形而上下位移，不受周围土体的影响，沉降杆与地下暗敷管线通过固结体连接为一个整体，沉降杆随着管道变形而上下位移，观测沉降杆顶端的沉降数值即可得到所监测的地下暗敷管线的准确的沉降数值。本发明解决了在地下暗敷管线的上方不具备土方开挖条件，且由于空间有限或管道保护要求高时，则无法使用直接监测点法施工进行地下暗敷管线沉降监测的问题。
