房建基坑支护工程的钢管桩结合土钉墙施工技术

Construction Technology of Steel Pipe Pile with Soil Nailing Wall in Housing Foundation Pit Supporting Engineering

结合济南市莱芜区嬴兴华庭项目基坑支护工程实际情况,立足现有的施工经验和启示,结合基坑支护土钉墙施工技术参数,分析了钢管桩结合土钉墙施工技术的具体应用要点。分析表明:与其他支护技术相比,钢管桩结合土钉墙施工技术具有合理利用土体的自稳能力、结构轻型、柔性大、密封性好等优势,可满足房建基坑支护工程的稳定性要求,提升房建基坑支护效果,防止发生坍塌问题。

Combined with the actual situation of foundation pit supporting engineering of Yingxinghuating Project in Laiwu District,Jinan,based on the existing construction experience and technical parameters of foundation pit supporting soil nailing wall construction,this paper analyzes the specific application points of steel pipe pile combined with the soil nailing wall construction technology.The analysis shows that compared with other supporting technologies,the construction technology of steel pipe pile combined with soil nailing wall has the advantages of self-stabilityin soil body,light structure,large flexibility and good sealing,which can meet the stability requirements of foundation pit supporting engineering,so as to improve the supporting effect of the foundation pit and prevent collapses.
