Dry-connection assembly type grating underground diaphragm wall
The invention discloses a dry-connection assembly type grating underground diaphragm wall. The wall is formed by splicing prefabricated wall body units; the cross section of each prefabricated wall body unit is of a cavity concentric-square-shaped structure, the two sides are provided with grooves with the same length as the prefabricated wall body unit and pre-buried positioning profile steel, and anchoring connecting pieces are arranged at the two ends; each anchoring connecting piece is in a cavity box shape with an opening, the two sides are anchored to wall body longitudinal bars, and theconnecting ends are through and correspond to reserved hole channels of a wall body; the vertically adjacent prefabricated wall body units are anchored by performing aligned splicing on high-strengthconnecting steel bars and the connecting ends of the anchoring connecting pieces; and the transversely adjacent prefabricated wall body units mesh through the pre-buried positioning profile steel, sothat lateral grooves are spliced to form a grouting hole, and then the grouting hole is filled with a micro-expansion early-strength high-ductility cement-based composite material. The underground diaphragm wall is quick to install, good in waterproof performance and high in flexural rigidity, can also be used as a basement outer wall, and facilitates industrial production and construction of theunderground diaphragm wall.
本发明公开了一种干式连接的装配式格栅地下连续墙，由预制墙体单元拼接构成，预制墙体单元横截面为空腔回字形构造，两侧设有通长的凹槽和预埋定位型钢，两端布置有锚固连接件；所述锚固连接件为开口空腔盒形，两侧与墙体纵筋锚固，连接端贯通并对应墙体预留孔道；竖向相邻的预制墙体单元通过高强连接钢筋对位拼接锚固连接件连接端锚固；横向相邻的预制墙体单元通过预埋定位型钢咬合，使得侧向凹槽拼接形成注浆孔后，填以微膨胀早强高延性水泥基复合材料。本发明安装快捷，防水性能好，抗弯刚度大，可兼做地下室外墙，有利于地下连续墙的工业化生产和施工。
