Construction method of plain soil compaction pile
The invention discloses a construction method of a plain soil compaction pile. The construction method comprises the following steps that (1) a pile site is positioned and paid off; (2) water injection hole construction is achieved; the water injection hole coincides with a compaction pile hole in position; (3) the water injection hole is filled with granite; the water outlet end of a water pipe is put to the orifice of the water injection hole, a water meter valve is opened, water is injected according to the calculated water injection rate, and the water is permeated into a soil layer in a treatment range uniformly through the granite; (4) after water injection is completed for 4-6 days, layered soil samples at the centers of three piles and an original pile position are taken to perform a moisture content test, and when the average moisture content is 12% or above in the test, judging is achieved that the humidification is qualified; and (5) soil is filled in the compaction pile hole by a tamping and filling machine to form a pile. The construction method of the plain soil compaction pile has the beneficial effects that water injection and humidification are conducted on a land parcel with hard soil texture and the average water content value of undisturbed soil being 10% or below, the compaction hole forming effect can be improved, and the construction quality of the compaction pile is improved.
本发明公开了一种素土挤密桩施工方法，包括以下步骤：（1）桩位点定位放线；（2）注水孔施工；注水孔与挤密桩孔孔位重合；（3）将注水孔内填满米石；将水管出水端放至注水孔孔口，打开水表阀门，注入所计算出的注水量，将水通过米石均匀的渗入处理范围内的土层中；（4）待注水完成4‑6天，取3桩中心及原桩位分层土样做含水率试验，待试验达到平均含水率12%以上即加湿合格；（5）采用夯填机对挤密桩孔填土夯填成桩。有益效果在于：采用该素土挤密桩施工方法，对土质较硬，原状土含水率平均值在10%以下的地块进行注水增湿，有利于提高挤密成孔功效，并提高挤密桩的施工质量。
