The invention relates to the technical field of building foundation pit supporting, in particular to a protection type foundation pit supporting structure which comprises a top beam, an arc-shaped supporting frame, a transverse supporting assembly, a concrete stress filling and leveling layer, a screwing mechanism, an upper inclined support body, a waist beam and a positioning pile pressing plate, the top beam is arranged on the edge of the top of a foundation pit, and the concrete stress filling and leveling layer is used for fixing the top beam; an inner transverse support and an outer transverse support are vertically and fixedly installed on the inner side of the crown beam at equal intervals, arc-shaped supporting frames are installed on the outer sides of the inner transverse support and the outer transverse support, butt joint tables are symmetrically arranged on the two sides of the tail end of the outer transverse support in an outward extending mode, and reinforcing ribs are arranged on the butt joint tables. The butt joint table is fixedly connected with the tail end of the arc-shaped supporting frame in a press fit mode through a threaded fastener. Through joint use of the inner transverse support and the outer transverse support, the application uniformity of supporting force on the enclosure plate is improved, and the phenomenon that the supporting force is insufficient locally can be prevented.
本发明涉及建筑基坑支护技术领域，具体涉及一种防护型基坑支护结构，包括冠梁、弧形撑架、横撑组件、混凝土应力填平层、旋紧机构、上斜支架体、腰梁和定位桩压板，所述冠梁设在基坑顶部边沿，所述混凝土应力填平层用于固定所述冠梁，所述冠梁的内侧垂直等间隔固定安装有内横支架和外横支架，所述内横支架和外横支架外侧安装有弧形撑架，所述外横支架的末端两侧对称外伸式设有对接台，所述对接台设有加强筋，所述对接台通过螺纹紧固件与所述弧形撑架的末端固定压合连接。本发明通过内横支架和外横支架的共同使用，提高了对于围护板支撑力的施加均匀性，有利于防止局部出现支撑力不足的现象。
