Novel foundation pit supporting structure close to building and construction method
The invention provides a novel foundation pit supporting structure close to a building and a construction method, and relates to the technical field of building construction.The novel foundation pit supporting structure close to the building comprises a supporting pile, a top beam is arranged at the top of the supporting pile, a bracket is arranged on one side of the supporting pile, the bracket and the top beam are connected through a support, and the horizontal plane where the top beam is located is higher than the horizontal plane where the bracket is located; the support is installed in an inclined mode. According to the method, back pressure soil is reserved in a pit, the stability of a support pile is guaranteed, then a main body structure of a newly-built building in the pit is constructed, a bracket is built on the main body structure, after the main body structure and the bracket both reach the design strength, a support is erected between the bracket and a top beam, then the back pressure soil is excavated, and finally the remaining main body structure is constructed. And foundation pit backfilling is completed. The main body structure of the newly-built building in the pit is emphatically utilized, stress conversion is completed, deformation and sedimentation of the existing building are effectively controlled in the construction process, and the safety of the existing building is ensured.
本申请提供了一种临近建筑物的新型基坑支护结构及施工方法，涉及建筑施工技术领域，包括支护桩，支护桩的顶部设置有冠梁，以及，支护桩的一侧设置有牛腿，牛腿与冠梁之间通过支撑进行连接，冠梁所在水平面高于牛腿所在水平面，支撑呈倾斜状安装。本发明方法通过在坑内预留反压土，保证支护桩的稳定性，然后施工坑内新建建筑物的主体结构，以及在主体结构上建设牛腿，待主体结构和牛腿均达到设计强度后，在牛腿和冠梁之间架设支撑，然后开挖反压土，最后施做剩余主体结构，完成基坑回填。本发明重点利用坑中新建建筑物的主体结构，完成受力转换，在施工过程中有效控制既有建筑物的变形和沉降，确保既有建筑物的安全。
