Mountain high-fill area stratum soil body reinforcing method
The invention discloses a mountain high fill area stratum soil body reinforcement method, and relates to the technical field of soil body reinforcement, the method comprises the following steps: S1, construction preparation: measuring and calculating a plurality of high pressure jet grouting pile positions and a plurality of floral tube pile positions on the periphery of a to-be-constructed cast-in-situ bored pile position, and making marks; s2, high-pressure jet grouting pile construction; s3, lowering the steel floral tube; s4, grouting for the first time; a grouting gun head used for grouting grouting holes in the steel floral tube is arranged in the steel floral tube in a lifting mode, a directional grouting device used for directionally grouting cement slurry in the grouting gun head to the high-pressure jet grouting pile is detachably arranged on the grouting gun head, and grouting is conducted through the directional grouting device; s5, the second round of grouting is conducted, specifically, the directional grouting device is detached from the grouting gun head, and the grouting gun head is driven to conduct lifting grouting in the steel floral tube; and S6, supplementing the slurry. The method has the effect that the problem that the hole forming efficiency is reduced due to the situations of slurry leakage, hole collapse and the like in the hole forming process when drilling construction is conducted to the position below the steel casing is solved.
本申请公开了一种山地高填方区域地层土体加固方法，涉及土体加固技术领域，其包括以下步骤：S1.施工准备，在待施工钻孔灌注桩桩位周侧测算出多个高压旋喷桩桩位和多个花管桩桩位并做好标记；S2.高压旋喷桩施工；S3.钢花管下放；S4.第一轮注浆；钢花管内升降设置有用于对钢花管上注浆孔注浆的注浆枪头，在注浆枪头上可拆设置用于将注浆枪头内的水泥浆朝高压旋喷桩定向灌注水泥浆的定向注浆装置，通过定向注浆装置进行注浆；S5.第二轮注浆，将定向注浆装置从注浆枪头上拆下，驱使注浆枪头在钢花管内升降注浆；S6.补浆。本申请具有改善钻孔施工到钢护筒以下位置时成孔过程会出现漏浆和垮孔等情况导致成孔效率降低的问题的效果。
