Deep foundation pit supporting structure applying space composite structure and construction method of deep foundation pit supporting structure
The invention discloses a deep foundation pit supporting structure applying a space composite structure and a construction method of the deep foundation pit supporting structure. The deep foundation pit supporting structure comprises an outer side supporting structure, vertical steel latticed columns, vertical steel latticed column lower cast-in-place piles, horizontal web members, diagonal web members and a horizontal truss structure; the outer side supporting structure comprises row-by-row cast-in-situ bored piles arranged on a soil body on the periphery of a foundation pit and a crown beam pressed on the cast-in-situ bored piles; the vertical steel latticed columns are arranged on one side of the foundation pit, and every two vertical steel latticed columns form a group; the horizontal web members and the diagonal web members connect one group of vertical steel latticed columns and the two closest outer side cast-in-place piles into a vertical space combined supporting structure unit; and the vertical space combination supporting structure units are connected through the horizontal truss structures, and finally the novel space combination supporting structure described by the invention is formed. The height of the lateral force resisting section is increased, the deformation resisting capacity is enhanced, the overall stability of the supporting structure is guaranteed by means of the spatial effect of the structure, and meanwhile the purposes of guaranteeing the construction space, controlling the manufacturing cost and the like can be achieved.
本发明公开了一种运用空间组合结构的深基坑支护结构及其建造方法，包括外侧支护结构、竖向钢格构柱、竖向钢格构柱下灌注桩、水平腹杆、斜腹杆、水平桁架结构。外侧支护结构包括设置于基坑周边土体的连排钻孔灌注桩以及压在钻孔灌注桩上的冠梁。竖向钢格构柱布置于基坑一侧，每两根竖向钢格构柱为一组。水平腹杆及斜腹杆将一组竖向钢格构柱和最接近的两根外侧灌注桩连接成一个竖向空间组合支护结构单元。竖向空间组合支护结构单元间用水平桁架结构连接，最终形成本发明所描述的一种新型空间组合支护结构。本发明增大了抗侧力截面的高度，强化了抗变形能力，借助结构的空间效应保证支护结构整体稳定性，同时也能实现保证施工空间、控制造价等目标。
