Construction method of static pressure steel pipe carrier pile
The invention provides a construction method of a static pressure steel pipe carrier pile. The construction method is closely attached to the specific construction environment in the field of foundation reinforcement construction, the dead load of an existing building is used as the counter force of pile pressing, a unique static pressure technology that a pressing pipe filler is connected into the pile in a sleeved mode is adopted, the filler is extruded through static force of a jack, a carrier is formed at the bottom of the static pressure steel pipe pile, and therefore the action relation between the pile end of the static pressure steel pipe pile and a foundation soil body is changed. The bearing capacity of the static pressure steel pipe pile is further improved by improving the bearing capacity of the foundation soil body at the pile end. The method is easy, convenient and reliable to construct, meanwhile, no vibration or noise is generated in the construction process, and the method is better than a traditional carrier pile construction method conducted on the ground. By means of the method, the end bearing capacity of the static pressure steel pipe pile for foundation reinforcement construction can be remarkably improved, then the bearing capacity of the static pressure steel pipe pile is improved, and the reliability and adaptability of the static pressure steel pipe pile in the field of foundation reinforcement construction are wider.
本发明提出的一种静压钢管载体桩的施工方法，紧密贴合地基加固施工领域的具体施工环境，利用已有建筑物的自重荷载作为压桩的反力，采用独特的桩内套接压管填料静压工艺，使用千斤顶静力挤压填料，在静压钢管桩底形成载体，从而改变了静压钢管桩的桩端与地基土体之间的作用关系。通过提高桩端地基土体的承载力进一步提高静压钢管桩的承载能力。该方法施工简便可靠，同时在施工过程中没有震动和噪音产生，相比传统在地面进行的载体桩的施工方法更胜一筹。使用本方法，将会使地基加固施工的静压钢管桩的端承力显著提升，进而提高静压钢管桩的承载力，使静压钢管桩在地基加固施工领域的可靠性和适应性更加宽广。
