Retaining wall type high-speed railway subgrade coordinated settlement control construction method based on intelligent monitoring of adjacent existing lines
The invention discloses an adjacent existing line retaining wall type high-speed rail roadbed coordinated settlement control construction method based on intelligent monitoring, and relates to the technical field of constructional engineering.The overall construction sequence is as follows: firstly, intelligent monitoring instruments and equipment are laid to conduct automatic detection on a whole construction railway section, then a first metal separation net is constructed, and then a site is primarily leveled; and high-pressure jet grouting pile and isolation pile construction is carried out, foundation pit excavation and supporting are carried out after pile arrangement is completed, a retaining wall type roadbed construction stage is entered, and cantilever retaining wall roadbed filling is carried out. The construction method is simple, the influence on settlement of the adjacent existing lines in the construction process can be effectively reduced, the safety and comfort of the operation railway are guaranteed, the construction quality is high, differential settlement of the transition section of the new roadbed and the old roadbed is greatly reduced, an intelligent monitoring system is adopted for settlement and displacement monitoring in the whole construction railway section construction period, the deformation condition of the existing structure in the construction period is mastered in time, deformation overrun is controlled and treated in time, and the operation safety of a business line is ensured.
本发明公开了一种基于智慧监测邻近既有线挡墙式高铁路基协调沉降控制施工方法，涉及建筑工程技术领域，总体施工顺序为：先铺设智能监测仪器设备对整个施工铁路段进行自动化检测，再进行金属隔离网一施工，然后场地初平，进行高压旋喷桩与隔离桩施工，桩布置完以后进行基坑开挖支护，进入挡墙式路基施工阶段，悬臂挡墙路基填筑。本发明施工方法较为简单，能较为有效的降低施工过程中对邻近既有线沉降的影响，保证运营铁路的安全性和舒适性，施工质量高，新旧路基过渡段的差异化沉降大大的降低，整个施工铁路段施工期间，采用智能监测系统，进行沉降、位移监测，及时掌握施工期间既有结构物的变形情况，对变形超限及时进行控制和处理，确保营业线运营安全。
