Vacuum combined surcharge preloading construction method and system
The invention discloses a construction method and system for vacuum combined preloading. The construction method comprises the following steps that S1, a site is leveled; s2, laying a sand cushion layer; s3, measuring and setting out; s4, constructing a plastic drainage plate; s5, laying a sealing wall; s6, laying a vacuum filter pipe; s7, laying a sealing layer; s8, vacuumizing and loading: starting a vacuumizing pump to ensure that the vacuum pressure below the sealing layer is not less than 80KPa; s9, stacking and loading the stacked objects: stacking and loading the stacked objects on the sealing layer to a roadbed design elevation in a grading manner; s10, carrying out construction observation; settlement measuring structures such as the inclinometer pipe, the measuring rod and the displacement side pile are arranged, settlement observation can be conducted in the foundation drainage settlement consolidation period, and the construction quality can be guaranteed. Meanwhile, during heaping construction, a graded heaping construction method is used, settlement observation can be carried out after each stage of heaping construction, and the construction is guaranteed to be qualified, so that the heaping construction scheme is optimized.
本发明公开了一种真空联合堆载预压的施工方法及系统，施工方法包括以下步骤：S 1、场地平整；S2、铺设砂垫层；S3、测量放样；S4、塑料排水板施工；S5、布设密封墙；S6、铺设真空滤管；S7、铺设密封层；S8、抽真空加载：启动抽真空泵，使得密封层下真空压力不小于80KPa；S9、堆载堆载物：在密封层上分级堆载堆载物至路床设计高程；S10、施工观测；本发明设置有测斜管、测杆和位移边桩等沉降测量结构，可在地基排水沉降固结期间进行沉降观测，有助于保证施工质量。同时，本发明在堆载施工时，使用分级堆载施工法，可以对每级堆载施工后，进行沉降观测，取保施工合格，如此优化了堆载施工方案。
