Construction method of front grouting micro grouting steel pipe pile
The invention relates to a construction method of a front grouting micro grouting steel pipe pile, and belongs to the field of geotechnical engineering foundation reinforcement. The method mainly comprises the following construction steps of: 1, placing a drilling machine in place; 2, drilling to form a hole; 3, grouting for the first time; 4, lowering the steel pipe; 5, pre-grouting; 6, lowering a post grouting pipe; and 7, post-grouting. In the implementation process of the second step, a pile body steel pipe can be used as a drill rod for drilling and hole forming, the time for lifting a drill and detaching the drill rod of a drilling machine is saved, and the construction efficiency is improved. The quality of a pile body can be improved, and then the bearing capacity is improved. The method is simple and easy to implement, and reliable guidance can be provided for the foundation reinforcement technology in the field of geotechnical engineering.
本发明涉及一种前压浆微型注浆钢管桩施工工法，属于岩土工程地基加固领域。其主要包括以下施工步骤：一.钻机就位；二.钻进成孔；三.首次注浆；四.下放钢管；五.前压浆；六.下放后压浆管；七.后压浆。其中步骤二实施过程中，还可以将桩身钢管做为钻杆钻进成孔，省去钻机提钻和拆卸钻杆的时间，提高施工效率；进行前压浆施工，能够提高桩身质量，进而提高承载力。本发明简单易行，可为岩土工程领域地基加固技术提供可靠的指导。
