Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, the present invention provides a deep-layer artesian well plugging system and method with simple construction, easy operation and low cost, which avoids the artesian groundwater flow when the artesian well is completed; Large-scale layered water-stopping uses cement paste to flow or break through the cement paste, which prevents the failure of layered water-stopping caused by the failure of cement to solidify within the allowable time, prevents the permeability of groundwater, and prevents the underlying groundwater from flowing along the crack surface. The aquifer series formed by entering the upper aquifer achieves the effect of permanent sealing and water stop, and solves the problems existing in the prior art

Abstract

The invention belongs to the technical field of underground water monitoring, and particularly relates to a deep-layer pressure-bearing artesian well plugging system and method. The method adopting the deep-layer pressure-bearing artesian well plugging system for plugging includes the steps of installing a hydrostatic column, manufacturing flange plates, installing the flange plates, performing filling of biology expanding materials, performing temporary plugging and drainage pressure reducing after a pipe is lowered, calculating the usage amount of cast cement paste and injecting the cement paste through paste injecting pipes, so that layering water-stopping end openings are formed, and permanent layering water stopping is completed. The deep-layer pressure-bearing artesian well plugging method is simple in construction, easy to implement and low in cost, it is avoided that due to large pressure borne by a pressure-bearing artisan well, the cement paste used for layering water stopping flows or breaks through the cement paste, it is prevented that because the cement can not be solidified within allowed time, layering water stopping fails, permeability of underground water is stopped, it is avoided that the underground water on the bottom layer enters a water-bearing stratum on the upper layer along a fracture surface, so that crossing of the water-bearing stratum occurs, and permanent plugging water stopping is achieved.

Description

(1) Technical field [0001] The invention belongs to the technical field of groundwater monitoring, and in particular relates to a sealing system and method for deep pressure artesian wells. (2) Background technology [0002] In the traditional water level and water quality observation, to obtain the water level and quality of different aquifers, multiple wells must be drilled, and each well can only observe one layer of aquifer, which results in a large area, long construction time, and large capital investment. Now in the same well, the method of layered sealing is adopted to realize the monitoring of water level and water quality of different aquifers at the same time. This single-well multi-level monitoring well occupies a small area, and the construction is simple and the cost is reduced. However, in the construction process of single-well multi-level monitoring wells, it is necessary to adopt effective layered water-stopping methods to better complete the well completio...
