High-pressure jet grouting pile opening reinforcing method
The invention provides a high-pressure jet grouting pile opening reinforcing method, and relates to the technical field of high-pressure jet grouting pile construction.The high-pressure jet grouting pile opening reinforcing method comprises the following steps that S1, surveying and setting out are conducted, specifically, firstly, a construction axis is measured and set out according to a designed construction drawing and coordinate net points; s2, hole positions are determined, then the hole positions are determined on the construction axis, pile numbers, hole numbers and serial numbers are marked, and the ground elevation of each hole opening is measured according to the datum points; and S3, hole forming is conducted through the drilling machine, then the vacant site is drilled through the drilling machine, and during drilling, a main drilling rod of the drilling machine corresponds to the aligned hole site. In the process of cleaning the grouting pump and the slurry conveying pipeline, sewage can be fully cleaned through precipitation of the container and filtering of the filter screen, then the sewage can be repeatedly utilized, the cleaning effect can be guaranteed, meanwhile, water resources are saved, the construction cost can be effectively controlled during construction in a part of areas lack of water resources, and the construction efficiency is improved. The practicability is high, and the advancement is remarkable.
本发明提供一种高压旋喷桩洞口加固方法，涉及高压旋喷桩施工技术领域，所述高压旋喷桩洞口加固方法包括如下步骤：S1，测量放线，首先根据设计的施工图和坐标网点测量放出施工轴线；S2，确定孔位，然后在施工轴线上确定孔位，编上桩号、孔号、序号，依据基准点进行测量各孔口地面高程；S3，钻机造孔，然后通过钻机对空位进行钻孔，钻孔时，钻机主钻杆应对准孔位。本发明在清洗灌浆泵和输浆管路的过程中，可以通过容器的沉淀以及滤网的过滤来充分洁净污水，进而使得污水可以反复利用，不仅可以保证清洗效果，同时也节省了水资源，在部分水资源匮乏的地区施工时，可以有效控制施工成本，实用性较高，进步性显著。
