Abstract

The invention provides an integral mounting structure for emergency dewatering gas monitoring of a foundation pit in an ultra-thick water-rich aquifer. The integral mounting structure comprises an underground continuous wall, a depressurization well supporting frame, an operation platform, at least one protective cylinder, at least one dewatering well, at least one depressurization well, at leastone observation well, a recharge well, a generator set, a drainage system, an exhaust system and a monitoring system which are arranged in the foundation pit. The operation platform, the protective cylinders and the depressurization well supporting frame are fixedly connected and erected at the top of the underground continuous wall. The generator set is connected with the drainage system, the exhaust system and the monitoring system. A stratum at the foundation pit comprises an upper aquifer, a water-resisting layer and a lower water-rich aquifer which are sequentially arranged. The underground continuous wall is circular and partially located in the lower water-rich aquifer. According to the integral mounting structure for emergency dewatering gas monitoring of the foundation pit in theultra-thick water-rich aquifer, deep pit dewatering of the ultra-thick water-rich aquifer can be achieved under the emergency condition, safety is high, and underground water can be monitored.

Description

Technical field [0001] The invention relates to the field of construction environment rock-soil foundation pit engineering, in particular to a foundation pit emergency dewatering gas monitoring integral installation structure in a huge water-rich aquifer. Background technique [0002] Dewatering in deep pits along the river, large water volume, large electricity consumption, deep foundation pits, and greater risk. At present, there is no emergency foundation pit dewatering structure that can safely and effectively realize the dewatering of deep pits along the river. Summary of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the present invention provides an integrated installation structure for emergency dewatering gas monitoring of foundation pits in a huge water-rich aquifer, which can realize deep pit precipitation in a huge water-rich aquifer under emergency conditions and is safe High performance, can monitor groundwater. [0004] In order...
