Supporting method for preventing deformation of foundation pit
The invention provides a supporting method for preventing deformation of a foundation pit, which comprises the following steps: S1, constructing supporting piles: constructing on the inner side of a vertical supporting structure of the foundation pit, the supporting piles comprising a vertical pile and at least two inclined piles; s2, a supporting beam is constructed, specifically, construction is conducted at the bottom of back pressure soil reserved in a passive area, and the two ends of the supporting beam abut against the supporting piles and the inner wall of the foundation pit vertical supporting structure correspondingly; and S3, the back pressure soil is excavated, and a foundation bed and a foundation bottom plate of the underground structure are constructed. According to the supporting method, the construction efficiency of the foundation slab can be improved, the foundation cushion layer and the foundation slab obtained through construction are of an integrated structure, and the structural continuity and strength of the foundation slab are effectively improved; the supporting piles and the supporting beams do not need to be dismantled, the problem that an outer wall anti-leakage weak point is formed due to dismantling of the inclined throwing support is solved, the supporting piles and the supporting beams can vertically support the foundation cushion layer and the foundation base plate, and the stability of a building structure is improved.
本发明提供一种防止基坑变形的支护方法，该方法包括步骤：S1、施工支护桩：在基坑竖向支护结构的内侧施工，所述支护桩包括竖桩和至少两个斜桩；S2、施工支护梁：在被动区预留的反压土底部施工，所述支护梁的两端分别抵紧所述支护桩和所述基坑竖向支护结构的内壁；S3、挖除所述反压土，施工地下结构的基础垫层及基础底板。本发明提供的支护方法可提高基础底板的施工效率，并且施工得到的基础垫层和基础底板均为一体化结构，其结构连续性及强度得到有效提升；支护桩和支护梁可以不必进行拆除工作，避免了斜抛撑拆除而形成外墙防渗漏薄弱点的问题，支护桩和支护梁还可对基础垫层和基础垫板进行竖向支撑，提高建筑结构的稳定性。
