Foundation pit supporting method for floral tube pile grouting in stone nitrate area
The invention relates to the technical field of civil construction, in particular to a stone nitrate area floral tube pile grouting foundation pit supporting method. Comprising the following steps: measuring a hole site; a drilling machine is in place; processing the floral tube pile; grout overflow holes are formed in the side walls of the multiple floral tube piles, and a conical head is fixedly connected to one end of one floral tube pile in a sealed mode; the drilling machine pushes the floral tube pile; driving a floral tube pile by a hammer type pile machine; grouting is conducted; and supplementing the slurry. In a stone nitrate backfill area and quicksand type geology, the steel pipe pile is directly driven into the ground, so that the construction of a sleeve is omitted, the construction steps are reduced, the efficiency is improved, and the construction period of the whole project is greatly shortened; the grout overflowing holes formed in the steel pipe piles are arranged in a staggered mode, so that grout flowing out of the holes is distributed on the peripheries of the steel pipe piles in a staggered mode, after the grout is solidified, a soil layer outside the steel pipe piles is reinforced more firmly, the effect of improving the stability of the soil layer is achieved for stone nitrate backfilling areas and loose and soft geology such as quicksand, and the supporting effect of the steel pipe piles is improved.
本发明涉及土建施工技术领域，具体为一种石硝区花管桩注浆基坑支护方法；包括以下步骤：测定孔位；钻机就位；加工花管桩；在多根花管桩的侧壁上均设置溢浆孔，在其中一根花管桩的一端密封固定连接有锥形头；钻机推进花管桩；锤式桩机打进花管桩；注浆；补浆。在石硝回填区、流沙类地质中，直接将钢管桩打进地下，省去了套管的施工，减少了施工步骤，提高了效率，使得整个项目的施工周期大大缩短；钢管桩上开的溢浆孔交错设置，使得从孔内流出的浆液在钢管桩外周分布的错开，待浆液凝固，将钢管桩外的土层加固的更牢固，对石硝回填区、流沙类的这种松散且软的地质，起到了提高土层稳定性的作用，以及提高钢管桩支护作用。
