【摘要】 混凝土灌注桩因其施工效率高、成桩质量好、无污染、成本低等优点在建筑工程中得到了广泛的应用。但在地下成桩的施工过程中,不同的地质环境会严重影响成桩质量,因此有必要探讨在复杂地质环境下对护坡桩施工质量控制。以锦业时代C区·D5大道项目基坑支护工程为例,探究因建筑垃圾回填所致的地层复杂引起的混凝土灌注护坡桩施工问题、相应的处理方案、施工工艺、施工流程及质量控制。以及在施工过程中遇到的新的问题及相关处理措施等方面进行了详细的论述。结果显示项目部人员经讨论后所采用的施工方案可有效解决因建筑垃圾回填所致的地层环境复杂引起混凝土灌注桩施工难度增加这一难题,且保证了所成混凝土护坡柱的质量。因此本项目中分析问题思路处理方案和具体处理措施等对同类工程具有一定的参考价值。更多还原

【Abstract】 Cast-in-place piles with pumping concrete have been widely used in construction engineering because of their high construction efficiency, excellent quality, no pollution, and low cost. However, in the construction process of underground piling, different geological environments will seriously affect the quality of piling, so it is necessary to explore the quality control of slope protection pile construction in complex geological environment. Taking the deep foundation pit engineering of Jinye Times Area C · D5 Avenue project as an example, this paper explored the related construction processes, problems, corresponding solutions and its processes, and quality control of piles with pumping concrete under the complex ground condition caused by building waste backfill. Additionally, the new problems encountered in the construction processes and the related solving measures are discussed in detail. The results showed that the construction scheme adopted by the project personnel after discussion can effectively solve the problem in construction process of cast-in-place pile with pumping concrete in the complex geological environment caused by building waste backfilling. Simultaneously,ensure the quality of the cast-in-place pile with pumping concrete. Therefore, the analysis of problem ideas and specific solutions in this project have certain reference value for similar projects.更多还原
