Anti-collapse supporting piece for deep foundation pit excavation and supporting method using supporting piece
The invention discloses a deep foundation pit excavation anti-collapse supporting piece and a supporting method using the supporting piece, and relates to the field of deep foundation pit supporting, the deep foundation pit excavation anti-collapse supporting piece comprises a positioning base, a hoisting piece and a protective baffle installed on the side wall of the hoisting piece, and the positioning base is horizontally fixed to the pit edge of a deep foundation pit; one end of the positioning base extends to the intersection position of the pit edge and the slope and is hinged to the upper end of the hoisting piece, the hoisting piece extends to the bottom of the deep foundation pit along a slope soil body, and the clamping rollers horizontally advance from openings of the inverted-L-shaped clamping openings, slide to corners and then downwards slide to the bottom ends of the inverted-L-shaped clamping openings. The first cross rod and the second cross rod slide from the upper end to the lower end in the corresponding matched sliding opening, and the gap between the protection baffle and the hoisting piece is used for bearing soil particles rolling down from the deep foundation pit slope. The invention solves the problem that the existing foundation pit support can only enhance the support of the slope of the foundation pit and cannot prevent the edge of the upper end of the foundation pit from rolling down along the slope to hit constructors in the foundation pit to cause safety accidents.
本发明公开了一种深基坑挖掘防塌方支护件及使用该支护件的支护方法，涉及深基坑支护领域，包括定位基座、吊装件以及安装在吊装件侧壁的防护挡板，定位基座水平固定在深基坑坑边位置，定位基座一端延伸至坑边边缘与边坡交汇位置且与吊装件上端铰接，吊装件沿着边坡土体延伸至深基坑坑底，卡接辊从倒立L型卡接口开口水平推进，滑至拐角处再向下滑动至倒立L型卡接口的底端，横杆一和横杆二从对应的匹配滑动口内上端滑动至下端，利用防护挡板与吊装件之间的间隙作为承接深基坑边坡滚落泥土颗粒。本发明解决了现有基坑支护只能增强基坑边坡的支护，而不能够阻止基坑上端边缘位置沿着边坡滚落泥土颗粒，砸中基坑内的施工人员，引发安全事故的问题。
