Monitoring structure for enclosing of water gushing bore hole

Abstract

The invention provides a monitoring structure for enclosing of a water gushing bore hole. The monitoring structure comprises an orifice pipe mounted in the orifice of the bore hole as well as a monitor, a rubber backing plate, a limiting pressure plate and anchoring members, the rubber backing plate covers a port of the orifice pipe in a sealing way, the monitor is mounted in the side towards of the orifice pipe of the rubber backing plate, extends into the orifice pipe, and is connected with an external monitoring device via a lead which penetrates the internal of the rubber backing plate in a sealed way, the limiting pressure plate presses the rubber backing plate, the lower end of each anchoring member is fixedly mounted in the stratum in the periphery of the bore hole, and the upper end of the anchoring member is connected with the limiting pressure plate. Thus, gushing water in the port of the orifice pipe can be enclosed, the internal monitor can monitor bearing water in the bore hole for long time, and thus, plugging condition and water temperature and pressure of the gushing water bore hole can be monitored effectively, and validity of monitoring data is ensured.

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...

Problems solved by technology

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.
