Description

Hydrologic monitoring well separation device suitable for various geological environments and monitoring construction method
Technical Field
The invention relates to the field of geological exploration, in particular to a hydrologic monitoring well separation device suitable for various geological environments and a monitoring construction method.
Background
CN111622706a discloses a separation water stop device and method capable of reforming a strong closed single well double-layer hydrologic monitoring well, the patent application number is 2020106536605.
However, in the actual design and in the field construction, the following outstanding technical problems which cannot be solved by the patent are also found:
The exposed well wall of the monitoring well for construction monitoring is incomplete and smooth, so that the rubber is not completely attached to the well wall after being filled with water, the sealing effect is affected by the well wall condition, and when concrete grouting is caused, the situation of infirm sealing exists, and the main reason is that people cannot predict the well wall environment in the well at all;
In the prior art, even if a stratum is divided into an upper part and a lower part, because the middle pipeline is connected with the lower water-bearing layer during measurement, when the water pressure of the lower water-bearing layer is higher, water of the lower water-bearing layer flows out along a monitoring pipe and even can blow out, because the geological well has larger depth (the monitoring well depth in eastern area is generally more than 500 m), the existing sensor cable can be plastically deformed under the action of dead weight, and the position of an actual sensor cannot be determined during measurement, so that the accurate water level cannot be obtained;
Grouting is performed underwater, when a grouting pipe cannot be lowered to the top of the separation water stop device, the grouting pipe is easy to separate and delaminate after grouting, and the sealing effect cannot be guaranteed. Most importantly, when the separation water stop device cannot be completely attached to the well wall and has pores, injected concrete can enter the lower aquifer monitoring space along the well wall pores to block the aquifer pores and interfere with hydrological monitoring environments.
Most monitoring wells have a certain curvature due to the influence of factors such as stratum inclination angle, uneven stratum hardness, drilling process and the like. When the curvature is large, the separator can not be lowered to the design installation position;
When concrete is injected, the concrete is accumulated near the grouting pipe, the situation of uneven distribution exists, and the upper and lower hydrologic parts can permeate water for a long time.
This patent is based on 2020106536605 improvements and is incorporated herein by reference where not shown.

Referring to the prior art shown in fig. 1-5, if a part of the well wall has a necking or a hole collapsing, the technology shown in fig. 1-5 can cause local leakage, because the sealing of the whole structure depends on a single rubber material, but the patent adopts a plurality of rubber materials 4 from top to bottom to form a plurality of sealing points from top to bottom, and even if local failure occurs, the sealing failure can not be caused.
In the second embodiment, as a further improvement scheme or a parallel scheme or an alternative independent scheme, the steel plate rings 3 are connected with the steel pipes through connecting rods.

The defect aiming at the prior art is that even if the stratum is divided into an upper part and a lower part in the prior art, the pressure of underground water is sometimes very high and even blowout can be caused because a pipeline in the middle part is connected with the bottom part during measurement, the actual position of a sensor is not known at all because the hydrogeological well has a depth of 500 meters during measurement, and the leakage-proof threaded rod 101 can avoid that the high pressure of the ground directly causes mud blowout to influence hydromeasurement.
In the seventh embodiment, as a further improvement, a parallel arrangement or an alternative independent arrangement, the air leakage preventing threaded rod 101 is made of stainless steel, and the signal wire 103 penetrates through the middle part of the air leakage preventing threaded rod 101 and is exposed from the uppermost part.
