The invention relates to the field of building construction, in particular to a construction method for reinforcing soil around a pile body of a cast-in-place pile. The construction method comprises the following steps of: processing a seamless grouting pipe, and processing grout overflowing holes in the grouting pipe; drilling hole positions around the pile body of the cast-in-place pile by utilizing a crawler-type hydraulic down-the-hole drill, and enabling the grouting holes to be uniformly distributed around the outer side of the pile body of the cast-in-place pile; grouting from bottom totop by a high-pressure grouting machine until all the grouting holes are grouted; after all the grouting holes are grouted, pulling out the grouting pipe and sealing and fixing the grouting holes; and after the soil in a grouting area is solidified, carrying out cast-in-place pile drilling construction by utilizing a rotary drilling rig. According to the construction method disclosed by the invention, the strength among the soil is effectively enhanced, the hole forming quality is ensured, the phenomenon of hole collapse is prevented, and the phenomenon of sediment is reduced.
本发明涉及建筑施工领域，尤其是一种灌注桩桩身周围土体加固施工方法，加工无缝注浆管，由注浆管上加工有溢浆孔；利用履带式液压潜孔钻机在灌注桩桩身周围进行孔位钻进，使注浆孔均匀布置在灌注桩桩身外侧周围；高压注浆机由下向上进行注浆，直到所有的注浆孔完成注浆为止；所有注浆孔完成注浆后，拔出注浆管并对注浆孔进行封孔固定；注浆区域土体固化后，利用旋挖钻机进行钻孔灌注桩施工。本发明有效增强了土体间的强度，保证了成孔质量，防止塌孔现象的发生，减少了沉渣现象。
