Foundation pit protection device for highway bridge construction
According to the technical scheme, the highway bridge construction foundation pit protection device is characterized in that the highway bridge construction foundation pit protection device comprises two first hollow plates and two second hollow plates, protection plates are slidably connected to the two sides of the first hollow plates and the two sides of the second hollow plates correspondingly, and two symmetrical bidirectional lead screw assemblies are fixed to the first hollow plates; wherein connecting blocks are fixed to one sides of the two protection plates, two connecting rods are connected to the bidirectional lead screw assembly in a threaded mode, and the two connecting rods are fixedly connected with the two connecting blocks. According to the opening size of the highway bridge foundation pit, adjustment can be conducted, the applicability to highway bridge foundation pits of different sizes is improved, soil blocks and sand and stones around the opening of the highway bridge foundation pit can be blocked and prevented from sliding to the bottom of the foundation pit, meanwhile, collapse at the opening of the foundation pit can be avoided, the protection performance of the foundation pit is improved, and use of the foundation pit is guaranteed.
本发明公开了一种公路桥梁施工基坑防护装置，其技术方案要点是：包括两个第一空心板和两个第二空心板，所述第一空心板与所述第二空心板的两侧均滑动连接有防护板，所述第一空心板上固定有两个对称的双向丝杆组件，其中两个所述防护板的一侧固定有连接块，所述双向丝杆组件上螺纹连接有两个连接杆，两个所述连接杆与两个所述连接块固定连接；能够根据公路桥梁基坑的开口大小，进行调整，提高对不同尺寸的公路桥梁基坑适用性，可对公路桥梁基坑开口处周围的土块以及沙石阻挡，避免滑落到基坑底部，同时能够避免基坑开口处造成塌方，提高对基坑的防护性能，保障基坑的使用。
