Engineering foundation pit supporting and protecting structure
The invention relates to the technical field of foundation pit supporting, and provides an engineering foundation pit supporting protection structure which comprises a hollow air cushion, the hollow air cushion is used for covering the surface of a supporting plate and conducting elastic contact type protection on the supporting plate, a bottom round hole is formed in the bottom of the hollow air cushion, and a damping spring is fixedly connected to the inner wall of the hollow air cushion; a top round hole is formed in the top of the hollow air cushion, an arc-shaped blocking piece is fixedly connected to the top of the hollow air cushion, small ventilation holes are formed in the outer side of the arc-shaped blocking piece, the inner walls of the bottom round holes are slidably connected with the outer side of the embedding device, and the multiple bottom round holes are evenly distributed in the bottom of the hollow air cushion. And the plurality of damping springs are uniformly distributed on the inner wall of the hollow air cushion. By means of the technical scheme, the problems that in the prior art, when a foundation pit is deep, the supporting plate bears impact of debris such as gravel for a long time and is damaged, the supporting and retaining effect of the supporting plate is gradually reduced, and even potential safety hazards are caused by damage are solved.
本发明涉及基坑支护技术领域，提出了一种工程基坑支护防护结构，包括空心气垫，该空心气垫用于覆盖在支撑板表面并对支撑板进行弹性接触式防护，空心气垫的底部开设有底圆孔，空心气垫的内壁固定连接有减震弹簧，空心气垫的顶部开设有顶圆孔，空心气垫的顶部固定连接有弧形挡片，弧形挡片的外侧开设有通气小孔，底圆孔的内壁与嵌入装置的外侧滑动连接，底圆孔设置有多个，且多个底圆孔均匀分布在空心气垫底部，减震弹簧设置有多个，且多个减震弹簧均匀分布在空心气垫内壁。通过上述技术方案，解决了现有技术中的基坑深度较深时支撑板长时间承受碎石等杂物的撞击发生损坏会逐渐降低自身的支挡效果甚至可能会发生损坏造成安全隐患问题。
