Combined pile type and construction technology thereof
The invention belongs to the technical field of soft foundation treatment, and particularly relates to a combined pile type and a construction technology thereof.The combined pile type comprises gravel piles and high-pressure jet grouting piles, and the construction technology of the combined pile type comprises the following specific steps that S11, construction preparation is conducted; s12, pile testing is carried out to determine construction parameters; s13, surveying and setting out; s14, the vibroflotation pile machine is in place; s15, vibration tube sinking is carried out; s16, stone is added; s17, tube drawing through vibration; s18, the pile machine is moved; s21, determining parameters of the test pile; s22, surveying and setting out are carried out; s23, the jet grouting pile machine is moved in place; s24, trial spraying is carried out; s25, cement paste is prepared; s26, drilling is conducted; s27, pipe lifting and high-pressure jet grouting are conducted; and S28, the movable jet grouting pile machine is moved. The gravel piles and the high-pressure jet grouting piles are arranged in an array mode, so that the gravel piles and the high-pressure jet grouting piles are evenly distributed, the whole soft foundation is balanced, the conditions of local sinking and building wall cracking are avoided, and the overall load capacity of an original foundation is greatly improved.
本发明属于软地基处理技术领域，具体为一种组合桩型及其施工工艺，包括：碎石桩和高压旋喷桩，该组合桩型的施工工艺的具体步骤如下：S11：施工准备；S12：试桩确定施工参数；S13：测量放线；S14：振冲桩机就位；S15：振动沉管；S16：填加石料；S17：振动拔管；S18：桩机移位；S21：试桩确定参数；S22：测量放线；S23：移动旋喷桩机就位；S24：试喷；S25：制备水泥浆；S26：钻孔；S27：提管高压喷射注浆；S28：移动旋喷桩机移位。将碎石桩、高压旋喷桩按照阵列的方式排布，使得碎石桩、高压旋喷桩之间分布均匀，使得软地基整体较为均衡，避免出现局部下沉、建筑墙体开裂的情况，使原地基的整体负荷能力得到大大提高。
