| titleOfInvention | Dynamic Monitoring System and Monitoring Method of Confined Water Precipitation in Deep Foundation Pit |
| abstract | The invention discloses a deep foundation pit pressurized water dewatering dynamic monitoring system and a monitoring method, including a monitoring well, characterized in that the monitoring well is provided with a dewatering well pipe, and the bottom of the dewatering well pipe is provided with a filter pipe in the area of the pressurized water layer to be measured , the bottom of the filter tube is provided with a sedimentation tube, the bottom of the sedimentation tube is sealed, the upper part of the precipitation well tube and the hole wall of the monitoring well is filled with sealing clay, and the lower part of the precipitation well tube and the hole wall of the monitoring well is filled with There is water-stop clay, sand and gravel filter materials are filled between the filter pipe and the hole wall of the monitoring well, and between the sedimentation pipe and the hole wall of the monitoring well. The sensors are respectively connected to the data acquisition instrument through wires, the data acquisition instrument is connected to the monitoring computer, and the filter tube is connected to the external pump through the suction pipe. The advantage is that it can dynamically, accurately and reliably measure the water level drawdown of the confined water, and can determine the pressure of the foundation pit in real time. The drawdown of the water determines when the pumping well stops working. |
