Dynamic monitoring system and monitoring method of deep foundation pit confined water drawdown
The invention discloses a dynamic monitoring system and a monitoring method of deep foundation pit confined water drawdown. The dynamic monitoring system comprises a monitoring well and is characterized in that a drawdown well pipe is arranged in the monitoring well; the bottom of the drawdown well pipe is provided with a filter pipe in a confined water layer area to be tested; the bottom of the filter pipe is provided with a precipitation pipe; the bottom of the precipitation pipe is sealed; a gap between the upper part of the drawdown well pipe and the hole wall of the monitoring well is filled with hole sealing clay; the gap between the lower part of the drawdown well pipe and the hole wall of the monitoring well is filled with waterstop clay; the gap between the filter pipe and the hole wall of the monitoring well as well as the gap between the precipitation pipe and the hole wall of the monitoring well is filled with gravel filter materials; the inner wall of the drawdown well pipe is longitudinally uniformly provided with a plurality of hole pressure sensors; each hole pressure sensor is respectively connected with a data acquisition instrument via a lead; the data acquisition instrument is connected with a monitoring computer; the filter pipe is communicated with an external water suction pump via a water suction pipe. The dynamic monitoring system has the advantages that confined water level drawdown can be dynamically, precisely and reliably measured, foundation pit confined water drawdown can be judged in real time, and time for a pumping well to stop working is determined.
