Civil engineering foundation pit protection structure and construction method thereof

MAO JIANRONG / WANG SHAOJING / SHANGGUAN FUZUAN

The invention belongs to the technical field of building construction, and discloses a civil engineering foundation pit protection structure which comprises a fixing plate, a baffle is hinged to one side of the fixing plate, a sliding groove is formed in the middle of the side, close to the fixing plate, of the baffle, a limiting block is movably clamped to the inner side of the sliding groove, and a limiting plate abuts against the middle of the side, close to the baffle, of the limiting block. And the other side of the limiting plate is fixedly connected with fixing nails at equal intervals. Through cooperation of a limiting block, a movable plate, a movable block, a pull rope, a clamping block, a magnet block and other structures, the device is convenient to fix, the clamping block is pulled leftwards by the pull rope, so that the clamping block is not attracted to the magnet block, the clamping block is not clamped to a clamping groove, the limiting block can slide downwards, and the clamping block can be attracted leftwards through magnetic force of the magnet block by loosening the movable block; and through clamping connection of the clamping blocks and the clamping grooves and cooperation of the limiting blocks, the movable plates, the movable blocks, the pull ropes, the clamping blocks, the magnet blocks and other structures, the device is convenient to fix.

本发明属于建筑施工技术领域，且公开了一种土建基坑防护结构，包括固定板，所述固定板的一侧铰接有挡板，所述挡板靠近固定板一侧的中部开设有滑槽，所述滑槽的内侧活动卡接有限位块，所述限位块靠近挡板一侧的中部抵接有限位板，所述限位板的另一侧等距固定连接有固定钉。本发明通过限位块、活动板、活动块、拉绳、卡块、磁铁块等结构配合使得装置便于固定，拉绳将卡块向左拉动，使得卡块不与磁铁块吸附，使得卡块不与卡槽卡接，使得限位块能够向下滑动，通过松开活动块，通过磁铁块的磁力能够将卡块向左吸附，通过卡块与卡槽卡接，通过限位块、活动板、活动块、拉绳、卡块、磁铁块等结构配合使得装置便于固定。
