Grouting anchor cable truss structure for building deep foundation pit and construction method
The invention discloses a grouting anchor cable truss structure for building a deep foundation pit and a construction method.The grouting anchor cable truss structure comprises two grouting anchor cables (6), two trays (8), two sets of porous clamping piece type anchorage devices (9) and a steel channel beam (7), the two grouting anchor cables (6) penetrate through two cement mixing piles (4) respectively and penetrate into drill holes (5) of a foundation pit wall (2), and the two grouting anchor cables (6) are arranged in parallel; a plurality of mutually embedded cement mixing piles (4) are arranged between the two cement mixing piles (4); the tail portions of the two grouting anchor cables (6) penetrate through holes in the steel channel beam (7), and a tray (8) and a porous clamping piece type anchorage device (9) are installed on the grouting anchor cables (6). According to the structure, the overall supporting strength and the cooperative bearing capacity of the pile anchor of the foundation pit wall are improved, and the stability and safety of the foundation pit under specific conditions of a building can be guaranteed.
本发明公开了一种用于建筑深基坑的注浆锚索桁架结构及施工方法，该结构包括2根注浆锚索(6)、2个托盘(8)、2套多孔夹片式锚具(9)和1根槽钢梁(7)，2根注浆锚索(6)分别穿过2根水泥搅拌桩(4)并深入到基坑壁(2)的钻孔(5)处，呈平行布置，2根水泥搅拌桩(4)之间布置多个相互嵌入的水泥搅拌桩(4)；2根注浆锚索(6)尾部穿过槽钢梁(7)上的孔，并安装托盘(8)和多孔夹片式锚具(9)。该结构提高了基坑壁桩锚整体支护强度和协同承载能力，可保障建筑特定条件下的基坑稳定性和安全性。
