Special-shaped I-steel assembled lattice double-prestress stiff TRD underground diaphragm wall and construction method thereof
The invention discloses a special-shaped I-steel assembled lattice double-prestress stiff TRD underground diaphragm wall and a construction method thereof, a plurality of socket type special-shaped I-steels which are continuously and transversely arranged are arranged in a TRD cement soil underground diaphragm wall, and each socket type special-shaped I-steel comprises a linear web and four flanges; the end parts of the adjacent flanges on the side parts of the webs of the adjacent socket and spigot type special-shaped I-shaped steel are connected; every two adjacent socket type special-shaped I-beams form a lattice unit body, the inner sides of the lower ends, close to the flanges, of the middles of the lattice unit bodies are provided with locking anchoring ends, and anchoring bearing plates are pressed in the middles of the tops of the lattice unit bodies; an anchor point hole is formed in the center of the anchoring bearing plate, the anchor point hole is connected with the fore shaft anchoring end through prestressed steel cables, and the upper ends of the four prestressed steel cables penetrate through the anchor point hole and then are tensioned and fixed. According to the invention, the compressive strength in a three-direction pressed state and the horizontal rigidity for resisting lateral force can be improved through double prestressing force.
本发明公开了一种异形工字钢拼装格构双预应力劲性TRD地下连续墙及其施工方法，在TRD水泥土地下连续墙内设有若干个连续横向布置的承插式异形工字钢，承插式异形工字钢包括直线型腹板和四个翼缘；相邻的承插式异形工字钢腹板侧部的邻近翼缘的端部相连；每两个相邻的承插式异形工字钢组成一个格构单元体，格构单元体中部的邻近翼缘的下端内侧均设有锁口锚固端，格构单元体顶部的中部压有锚固承压板；所述锚固承压板的中心设有锚点孔，所述锚点孔与锁口锚固端之间分别通过预应力钢索连接，四根预应力钢索上端穿过锚点孔后张拉固定。本发明能通过双预应力提高三向受压状态抗压强度和抵抗侧向力的水平刚度。
