Foundation pit roadbed backfilling structure
The invention relates to a foundation pit roadbed backfilling structure. The foundation pit roadbed backfilling structure comprises a foundation pit, two concrete retaining walls and a bubble concretelayer; a plurality of embedded pipes are embedded in each concrete retaining wall; a lead screw is in threaded connection with the interior of each embedded pipe; one end of each lead screw is fixedly sleeved with a first rotating part, and the other end of each lead screw is fixedly connected with a drill bit; a horizontal groove is formed in one end of each lead screw; a limiting device is installed in each horizontal groove; the limiting device comprises a horizontal pipe and a driving mechanism; a plurality of groups of limiting mechanisms are sequentially arranged on the horizontal pipealong the axial direction of the horizontal pipe; each limiting mechanism comprises a plurality of connecting blocks sequentially arranged in the circumferential direction of the horizontal pipe; a connecting rod is hinged to the end, away from the horizontal pipe, of each connecting block; a limiting block is hinged to the end, away from the corresponding connecting block, of each connecting rod;and a through hole allowing the corresponding limiting block to slide in the radial direction of the horizontal pipe is formed in the side wall of each horizontal groove. According to the foundationpit roadbed backfilling structure of the invention, the concrete retaining walls and the side wall of the foundation pit can be connected more firmly.
本发明涉及一种基坑路基回填结构，其包括基坑、两个砼挡墙以及气泡混凝土层，每个所述砼挡墙内预埋有多个预埋管，每个所述预埋管内螺纹连接有丝杠，所述丝杠的一端套设固定有第一转动部，另一端固接有钻头；所述丝杠的一端开设有水平槽，所述水平槽内安装有限位装置，所述限位装置包括水平管以及驱动机构；所述水平管上沿其轴向依次设置有多组限位机构；每组所述限位机构包括沿水平管的周向依次设置的多个连接块，每个所述连接块远离水平管的一端铰接有连杆，所述连杆远离连接块的一端铰接有限位块，所述水平槽的侧壁开设有用于供限位块沿水平管的径向滑移的通孔。本发明能够使砼挡墙与基坑侧壁连接地更加牢固。
