Recoverable multilayer air bag type pore water pressure gauge embedding and recycling method
The invention discloses a method for burying and recycling a recyclable multi-layer air bag type pore water pressure gauge, and relates to the related technical field of pore water pressure gauges, and the method comprises the following steps: step 1, the burying method comprises the following steps: drilling a hole or burying a sleeve at a preset position; preparing an inflatable air bag; a pore water pressure gauge is placed at a preset depth position; filling the periphery of the pore water pressure gauge with a filter material; placing an air bag above the filter material, and then inflating and expanding; the upper portion of the uppermost layer of inflatable air bag is filled with a water stop material; step 2, the recovery method comprises the following steps: removing the water stop material above the uppermost inflatable airbag; deflating the gas of the uppermost inflatable airbag, and lifting the uppermost inflatable airbag out of the drill hole or the casing pipe; and the pore water pressure gauge on the uppermost layer is taken out. The air bag capable of being inflated and deflated is arranged, air is deflated after measurement is finished, and the air bag and the pore water pressure gauge are lifted out, so that the purpose of recycling is achieved.
本发明公开了一种可回收多层气囊式孔隙水压力计埋设及回收方法，涉及孔隙水压力计相关技术领域，包括包括如下步骤：步骤1：埋设方法如下：在预定位置钻孔或埋设套管；准备可充气的气囊；预定深度位置放置孔隙水压力计；在孔隙水压力计的周围填埋滤料；在滤料上方放置气囊，然后进行充气膨胀；在最上层充气气囊上方填埋止水料；步骤2：回收方法如下：去掉最上层充气气囊上方的止水料；将最上层充气气囊的气体放掉，从钻孔或者套管中提出；将最上层的孔隙水压力计提出。本发明通过设置可以充气放气的气囊，待测量结束后放掉气体将气囊和孔隙水压力计提出，以达到回收再利用的目的。
