摘要
某工程基坑开挖施工中,在基坑的不同位置分别采用了机械冲孔桩+板墙+预应力锚索、锚杆+挂网喷锚+锚索和高压旋喷桩止水帷幕墙+钢管桩的支护方法,介绍了施工过程中边坡局部自稳能力不足、基坑突涌情况的应急措施。监测结果显示,基坑支护结构处于稳定状态,有效地解决了临江深基坑边坡的止水难题,确保了基坑边坡的安全稳定和正常施工。
In excavation construction of some project,bracing techniques are adopted in different part such as technology of mechanical punched pile,plate wall and prestressed anchor cable,anchor,anchoring shotcrete with wire mesh and anchor cable,as well as technology of high pressure jet grouting pile waterproofing curtain and steel pipe pile.Furthermore,the author introduces emergency measures for lack of slope self-stability and water-inrushing.Monitoring results show that supporting structure is on stable state,the problem of water seal is solved,which makes slope stable.
