基于岩土工程基础施工中深基坑支护施工技术分析

Analysis of Deep Foundation Pit Support Construction Technology Based on Geotechnical Engineering Foundation Construction

深基坑支护施工技术作为岩土工程施工的重要环节,具有稳固和支撑的效果,在实际施工过程中容易出现许多的问题,要详细分析基坑支护施工技术的基本特点和应用类型。基坑支护施工技术的基本特点包括水文地质条件十分复杂、地下管线干扰性强、周围建筑物的影响强烈,技术类型包括土钉墙技术、锚杆支护技术、旋喷桩技术、钻孔灌注桩技术、内支撑梁支护技术。深基坑支护施工技术的要点则可从钻孔和埋设准备工作、冠梁施工、土方开挖、角撑梁施工要点、内撑梁施工流程、换撑施工要点几个方面进行分析,在此基础上,提出相应的管理改善建议,如设计有效的组织方案、分析现有制度、明确要点和步骤、加大监测力度等。

As an important part of geotechnical engineering construction,deep foundation pit support construction technology has the effect of stabilization and support,many problems are prone to occur in the actual construction process,and the basic characteristics and application types of foundation pit support construction technology should be analyzed in detail.The basic characteristics of foundation pit support construction technology include very complex hydrogeological conditions,strong interference of underground pipelines,and strong influence of surrounding buildings;technical types include soil nailing wall technology,bolt support technology,rotary shot pile technology,drilling Cast-in-place pile technology,and internal support beam support technology.The main points of deep foundation pit support construction technology can be analyzed from the aspects of drilling and burying preparations,crown beam construction,earthwork excavation,corner brace beam construction points,inner brace beam construction process,and bracing construction points.On this basis,corresponding management improvement suggestions are put forward,such as designing effective organizational plans,analyzing existing systems,clarifying key points and steps,and increasing monitoring efforts.
