逆作法基坑中格构柱施工的质量控制实践应用

Practical Application of Quality Control for Construction of Lattice Column in Foundation Pit with Reverse Method

通过逆作法基坑立柱桩中格构柱施工质量控制的过程实施,在前人应用的基础上进一步研究如何在施工过程中保证立柱桩中格构柱施工质量,特别是垂直度等技术参数的控制。经过后期的基坑施工检验发现,该工程立柱桩施工取得了较好的效果,所有桩的施工质量均符合图纸及规范要求,为后续施工提供了良好的施工条件,也大大降低了立柱桩及后续施工资源消耗和工程造价。

Through the implementation of the construction quality control process of the lattice column in the middle pillar pile of the foundation pit by the reverse construction method,based on the predecessors’ application,we further studied how to ensure the construction quality of the lattice column in the column pile during construction,especially the control of the technical parameters such as perpendicularity. After the construction of foundation pit inspection later found,and achieved good results of pile foundation construction of the project,the construction quality of all piles were in accordance with the drawings and specifications,provided good conditions for the subsequent construction,but also greatly reduced the pile and the subsequent construction of resource consumption and construction cost.
