Support-free environment-friendly ecological construction method pile construction method and foundation pile structure
The invention discloses a support-free environment-friendly ecological construction method pile construction method and a foundation pile structure, and relates to the field of foundation device protection, and the method comprises the following steps: rotary drilling and hole forming: adopting a rotary drilling rig to drill and excavate at a construction position, and performing jump excavation on the rotary drilling and hole forming every 2-3 piles; liquid solidified soil is poured, specifically, the liquid solidified soil is poured into the rotary digging formed hole; the section steel is inserted, specifically, before insertion, the section steel is derusted under the dry condition, the surface of the section steel is coated with an anti-friction material, and the section steel is inserted before initial setting of the liquid solidified soil so as to improve the anti-pressure ability to the soil; top beam construction: arranging a closed reinforced concrete top beam at the top of the pile, embedding the profile steel into the top beam, and wrapping the profile steel with an antifriction material; the non-support environment-friendly deep foundation pit support system is formed through the ecological construction method piles, the section steel and the pre-stressed anchor cables, the liquid solidification diagram is inserted into the section steel to form the piles after solidification, the soil retaining and bearing capacities are achieved, and the underground water blocking and seepage preventing effects are achieved.
本发明公开了一种无支撑环保生态工法桩施工方法及基桩结构，涉及基础装置的保护领域，包括如下步骤：旋挖成孔：采用旋挖钻机在施工处进行钻孔开挖，旋挖成孔隔2‑3条桩跳挖；灌注液态固化土：将液态固化土灌注到旋挖成孔中；插入型钢：插入前，在干燥条件下对型钢除锈，并在表面涂刷减摩材料，在液态固化土初凝前插入型钢，以提高对泥土的抗压能力；冠梁施工：在桩顶部设置封闭的钢筋混凝土冠梁，型钢埋入冠梁处采用减摩材料包裹；本发明通过生态工法桩、型钢、预应力锚索，形成无支撑环保深基坑围护体系，液态固化图插入型钢凝固后形成桩，既具有挡土、承载能力，又具有地下水阻隔防渗作用。
