Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings and examples. It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. For the convenience of description, if the words "up", "down", "left" and "right" appear in the following, it only means that the directions of up, down, left and right are consistent with the drawings themselves, and do not limit the structure.

[0033] An underground cavern gas storage, such as figure 1 As shown, including the surrounding rock 6 of the gas storage, a plurality of concrete linings 4 built close to the inner wall of the surrounding rock 6 of the gas storage, forming a concrete lining split 2 between two adjacent concrete linings 4; The concrete lining 4 encloses and forms a cylindrical structure, and the concrete lining joints and anti-air seepage structures are circumferentially ...

Abstract

The invention discloses an underground rock cavern gas storage and concrete lining joint anti-gas-seepage structure. The anti-gas-seepage structure comprises a groove formed in an opening of a concrete lining joint and a sealing strip located in the groove. A cover board is installed at a notch of the groove, a filler is filled among the wall surface of the groove, the cover board and the outer wall surface of the sealing strip, a first spring and a second spring are arranged in the sealing strip, and the two ends of the first spring and the two ends of the second spring are both tightly pressed on the inner wall of the sealing strip. The anti-gas-seepage structure solves the problem that an existing underground gas storage lining joint sealing treatment structure is insufficient in long-term sealing efficiency.

Description

technical field [0001] The present invention relates to an underground cavern gas storage and concrete lining joints anti-air seepage structure, in particular to a cave-type underground gas storage project for compressed air energy storage power station, large-scale natural gas underground cavern gas storage project, etc. The sealing and anti-leakage device of high-pressure gas in the field, especially the device for sealing high-pressure compressed gas with frequent high and low pressure alternating changes. Background technique [0002] Under the existing technical conditions, low-permeability or impermeable materials (3 steel plates, rubber plates or plastic plates) are used as the material of the sealing layer for cavern-type underground gas storage, and the lining (5) behind the sealing layer generally adopts integral pouring concrete Force-transmitting structural layer as a sealing layer. The pressure of the compressed air underground gas storage is generally as high ...
