Title:
METHOD FOR CONSTRUCTING GROUNDWATER MONITORING WELL IN PRB WALL
Document Type and Number:
WIPO Patent Application WO/2021/004143
Kind Code:
A1
Abstract:
The present application discloses a method for constructing a groundwater monitoring well in a PRB wall body. The method comprises: cutting a PRB wall body, mounting a wall body side wall support, performing drilling and positioning for a monitoring well, mounting a monitoring well mounting sleeve for pre-burying of the monitoring well, mounting a monitoring well positioning support frame, mounting a monitoring well pipe, filling the monitoring well with a filter material and a well seal material, filling the wall body with a dielectric material, covering the wall body with a soil layer, removing the monitoring well mounting sleeve, removing the wall body side wall support, shaping and washing the monitoring well, and finally, completing mounting of a front portion of the monitoring well, such that the monitoring well is pre-buried. The method avoids a complex process in which a well is re-drilled after a deep hole formed by performing rotary drilling on a PRB is filled, ensures that the monitoring well meets construction specifications, operates stably, allows groundwater to be monitored and sampled, and allows the PRB technology to be implemented and evaluated.
