I-shaped precast concrete pile supporting method
The invention belongs to the field of building construction methods, and particularly relates to an I-shaped precast concrete pile supporting method which comprises the following steps: S1, according to a geological exploration report, determining the section size and reinforcement of an I-shaped supporting pile through calculation, and conveying the I-shaped supporting pile to a construction site after factory production is completed and the strength is reached; s2, before a foundation pit is excavated, double-shaft cement soil mixing piles are adopted for hole guiding, and I-shaped concrete supporting piles are inserted before cement soil is initially set; and S3, in the foundation pit excavation process, earth is excavated to the elevation position of the pile top, a concrete cross beam is constructed, and excavation can be conducted to the designed elevation after the concrete strength reaches 100%. According to the I-shaped precast concrete pile supporting method, the construction progress and the construction quality of a foundation pit supporting project are guaranteed, the purposes of saving raw materials and cost are achieved, rainwater can be prevented from permeating into the foundation pit, and the probability of collapse of the foundation pit is reduced.
本发明属于建筑施工方法领域，尤其是涉及一种工字形预制混凝土桩支护方法，该方法包括以下步骤：S1、依据地勘报告，通过计算，确定工字形支护桩截面尺寸以及配筋，工厂生产完成并达到强度后运送至施工现场；S2、基坑开挖前，采用双轴水泥土搅拌桩进行引孔，待水泥土初凝前将工字形混凝土支护桩插入；S3、基坑开挖过程中，先将土方开挖至桩顶标高处，施工混凝土贯梁，待混凝土强度达到100％后方可开挖至设计标高。本发明的工字形预制混凝土桩支护方法，既保证基坑支护工程施工进度和施工质量，又达到节约原材料和节约成本的目的，而且能够防雨水渗入基坑，降低基坑塌方的概率。
