Embodiment 1

[0035] This embodiment provides a method for constructing a groundwater barrier device, such as figure 1 shown, including the following steps:

[0036] Step 1: If figure 2 As shown, the edges of a plurality of water-proof membranes 101 are pasted together end to end to obtain the impermeable membrane 100 to be used, and the two sides of the impermeable membrane 100 to be used are cut so that the two sides of the impermeable membrane 100 to be used are parallel and It is at a set angle with the edge of the water-proof membrane 101; the total width of the anti-seepage membrane 100 to be used meets the height requirement of the groundwater barrier device, and the anti-seepage performance of the anti-seepage membrane 100 to be used meets the test requirements, so The edge of the water-separating membrane 101 is the edge in the width direction of the water-separating membrane 101 . In this step, the set angle is 3°-5°, preferably 4°. The height of the anti-seepage membrane 100 ...

Embodiment 2

[0048] The present invention also provides a groundwater barrier device constructed using the groundwater barrier device construction method described in any of the schemes in Embodiment 1. The groundwater barrier device in this embodiment has good anti-seepage performance, is convenient for construction, and can be quickly Efficient laying finishes.

Abstract

The invention provides an underground water obstruction device building method and an underground water obstruction device. The underground water obstruction device building method comprises the following steps that water isolation membranes are adhered to the ground to obtain a standby impermeable membrane, the sealing performance of the impermeable membrane is tested, the impermeable membrane isinclined at a set angle and is coiled into a reel shape after passing the sealing performance test, an impermeable membrane component in the reel shape is unfolded to form a smooth impermeable membrane through a slideway component arranged on a cut, and multiple smooth impermeable membranes form a whole in a sealing connection manner. In the underground water obstruction device building method, as the thickness of an adhesion position of each water isolation membrane is two times the thickness of the rest position, influence on the smoothness by coiling or unfolding can be avoided by enablingthe standby impermeable membrane to be inclined at a certain angle; and by adhering each water isolation membrane in a width direction on the ground surface, each water isolation membrane with an enough width and an enough length is formed, and the water isolation effect of the underground water obstruction device is fully ensured.

Description

technical field [0001] The invention relates to the technical field of groundwater protection, in particular to a method for constructing a groundwater barrier device and the groundwater barrier device. Background technique [0002] The implementation of large-scale and high-intensity coal mining in coal mining areas will inevitably have a negative impact on water resources. The tunnels and goafs formed by coal mining have affected the movement and storage of surface water and groundwater, changed the circulation of groundwater, and caused a series of problems, such as river water cut-off, groundwater level drop, spring water flow sharply reduced or dry up. Water resource protection has become an important part of the sustainable development of coal. [0003] For this reason, underground reservoirs will be built in coal mining areas to prevent leakage. A barrier device will be installed in the underground reservoir, and a water-proof film will be added to the barrier devic...
