WU FEI / LI BIN / ZHAI HONGJIE / LIANG ZHONGMING / LIANG MIANXI

The slope supporting structure comprises a foundation pit slope and a supporting mechanism, the supporting mechanism comprises a supporting bottom plate, an adjusting seat connecting seat and an overturning baffle, a limiting groove is formed in the middle of the upper end of the supporting bottom plate, a sliding block is slidably connected to the inner wall of the limiting groove, and a supporting rod is hinged to the bottom end of the sliding block; the foundation pit slope reinforcing device has the following advantages that water on a foundation pit slope can be conveniently drained in time in rainy days through the water filtering holes in the overturning baffle, the connecting base can be pushed through cooperation of the guide rod and the threaded rod, grouting is conducted towards the interior of the positioning pipe through the grouting machine, and the foundation pit slope reinforcing device is convenient to use and high in practicability. And after the concrete is formed in the foundation pit, it can be effectively avoided that the supporting mechanism is squeezed by a slope and then moves, and the situation that soil in the foundation pit is soft and cannot be fixed is effectively avoided.

本发明公开了一种基坑施工的斜坡支撑结构及其施工方法，包括：基坑斜坡和支撑机构，支撑机构包括支撑底板、调节座连接座、翻转挡板，支撑底板上端中部开设有限位槽，限位槽内壁滑动连接有滑块，滑块底端铰接有支撑杆，支撑底板靠近拐角处开设有桩孔，支撑底板靠近桩孔一侧开设有加固孔，本发明具有以下优点：通过翻转挡板上的滤水孔便于雨水天气时基坑斜坡上的水及时排出，通过导杆配合螺纹杆可推动连接座，通过灌浆机向着定位管内部灌浆，使得混凝土通过定位管进入基坑内部，当混凝土在基坑内部成型后，则可有效避免支撑机构受到斜坡挤压进而移动，有效避免由于基坑内部土壤松软无法固定的情况。
