Borehole closed monitoring structure for gushing water

Abstract

The invention provides a closed monitoring structure for water gushing boreholes, which includes an orifice pipe installed at the hole of the borehole, and also includes a monitor, a rubber backing plate, a limit pressure plate and an anchor. On the port of the orifice tube, the monitor is installed on the side of the rubber pad facing the orifice tube, and the monitor protrudes into the orifice tube, and the monitor passes through the The wires are connected with external monitoring equipment, the limiting pressure plate is pressed on the rubber backing plate, the lower end of each anchor is fixedly installed in the formation around the borehole, and the upper end of the anchor is connected with the limiting pressure plate. The present invention can realize the sealing of the water gushing at the port of the orifice, and can realize the long-term monitoring of the pressurized water inside the borehole by means of the monitor installed inside the borehole at the same time of blocking, so it can effectively block the gushing water of the borehole And water temperature and water pressure are monitored to ensure the validity of the monitoring data.

Description

technical field [0001] The invention relates to the field of hydrogeological monitoring equipment, in particular to a water gushing borehole closed monitoring structure. Background technique [0002] In engineering reconnaissance and drilling, it is often necessary to conduct long-term observations of groundwater in boreholes. Usually, the observations are parameters such as water temperature and water pressure of groundwater with low pressure. The pressure monitoring device uses the monitoring instrument to be lowered into the borehole for long-term monitoring. However, in some special parts or areas with high orifice pressure and large water inflow, when it is necessary to monitor the water temperature and pressure of the confined water, it is difficult for the monitoring instrument to be lowered into the hole, and the water inflow in the borehole is not closed At this time, only the water temperature and water pressure at the orifice can be monitored, and the accuracy of...

However, in some special parts or areas with high orifice pressure and large water inflow, when it is necessary to monitor the water temperature and pressure of the confined water, it is difficult for the monitoring instrument to be lowered into the hole, and the water inflow in the borehole is not closed When it is used, only the water temperature and water pressure at the orifice can be monitored, and the accuracy of the monitored data is poor, and the effective monitoring purpose cannot be achieved.
