Method for reducing soil squeezing effect of precast pile
The invention discloses a method for reducing the soil squeezing effect of a precast pile. The method comprises the following steps that S1, stress release holes are formed in the inner side of a foundation pit fender post; S2, a plurality of sand piles are arranged on the outer side of the foundation pit fender post; S3, PVC pipes wrapped with filter screens are inserted into the sand piles, the PVC pipes in the multiple sand piles are connected through a pipeline, and a water pump is additionally arranged on the pipeline; and S4, a water pump continuously pumps seeping water in the PVC pipe. The invention provides the method capable of effectively reducing the soil squeezing effect of the precast pile.
本发明公开一种减少预制桩挤土效应的方法，包括以下步骤：S1、在基坑围护桩的内侧布置应力释放孔；S2、在基坑围护桩的外侧布置多个沙桩；S3、在沙桩内插入包裹了滤网的PVC管，用管道将多个沙桩内的PVC管连接，并在管道上加设水泵；S4、水泵持续抽取PVC管内渗水；本发明提供了一种能够有效减少预制桩挤土效应的方法。
