Description

Three-stage plug-in engagement sealing connection device with water stop strip

Technical Field

The utility model belongs to the technical field of the water conservancy construction and the environmental improvement in pollution places such as petrochemical, ore deposit are adopted and are smelted, solid waste handles and relate to a sealing connection device between two adjacent HDPE geomembranes in being arranged in perpendicular flexible protective screen system especially.

Background

In the case of long-term storage of solid wastes, simple dumps, and irregular landfills, a vertical barrier system is currently generally used as a method for preventing leakage of underground contaminated water. The vertical barrier system is the fastest and safest method for blocking the flow of harmful underground liquid, and CN 102444145B discloses a porous sealing device for connecting a vertical flexible barrier system, which comprises an expansion water stop pad and connecting locks arranged on both sides of an HDPE geomembrane and keeping a seal with the HDPE geomembrane, wherein when the connecting lock on each HDPE geomembrane and the connecting lock on another HDPE geomembrane are fastened with each other to form a sealing device, an expansion water stop pad cavity for installing an expansion water stop pad is formed between the two fastening locks, and the expansion water stop pad is filled in the expansion water stop pad cavity.

In the embodiments of the present invention, a solution of forming seven-stage sealing by seven inflatable water stop gaskets is cited, which is claimed to ensure a permanent seal of the junction of the vertical flexible barrier system. Although the connecting and sealing structure provided by the scheme is theoretically feasible, in the actual use process, the product of the structure cannot be normally used, because when the connecting and locking pieces fixed on the two HDPE geomembranes are mutually matched to form the sealing device, an expansion water stop pad cavity for installing the expansion water stop pad is formed between the T-shaped structures which are mutually matched or between the T-shaped structures which are mutually matched and the inverted L-shaped structures. After two adjacent HDPE geomembranes are connected by the connecting locking pieces in an inserting manner, although an expansion water stop pad cavity for installing the expansion water stop pad is formed at the inserting connection positions of the connecting locking pieces, the expansion water stop pad can be quickly expanded when meeting water, the expansion multiple is more than 5 times, the lower sections of the inserting connection positions of the connecting locking pieces of the two adjacent HDPE geomembranes are positioned in a water area, mud liquid at the bottom of a groove is easy to precipitate, and the expansion water stop pad is difficult to insert, so that the strip-shaped expansion water stop pad is soft, the length of the strip-shaped expansion water stop pad is more than 30 meters, the insertion of the long soft expansion water stop pad into the expansion water stop pad cavity cannot be realized, because the soft expansion water stop pad inevitably contacts with the wall of the cavity when being inserted and dropped, the sticking effect exists between the two, and the soft expansion water stop pad can be gathered in the height direction only by moving the soft expansion, the soft expansion water stop gasket cannot be uniformly arranged in the preset waterproof cavity, so that the space which is sealed by water absorption expansion of the soft expansion water stop gasket is lack of filling and virtual filling, and the sealing performance cannot be guaranteed.

The constructor fixes the soft expansion water stop pad on the movable connecting locking piece, then inserts the soft expansion water stop pad together with the movable connecting locking piece, the effect is very poor because the fixed connecting locking piece is fixedly installed, but the verticality of the exposed end of the fixed connecting locking piece is not guaranteed, it is very difficult to smoothly insert the connecting locking piece to be inserted with the soft expansion water stop pad, in the inserting process, because the verticality of the movable connecting locking piece to be inserted in the moving down process can not be guaranteed, the movable connecting locking piece has certain sway, thus the expansion water stop pad is adhered in advance and is extremely easy to be contacted by the port part of the fixed connecting locking piece, the port of the fixed connecting locking piece cuts off the expansion water stop pad, the lower section of the cut expansion water stop pad can fall freely and is blocked at the lower part of the fixed connecting locking piece, thus the expansion water stop pad from moving down and inserting, but also causes the movable connecting locking piece to be not inserted in place. The upper section of the cut-off expansion water stop gasket can be blocked by the upper port of the fixed connection locking piece to be gathered and shrunk, so that the expansion water stop gasket cannot be smoothly inserted, and the connection locking pieces on two adjacent HDPE geomembranes are mutually matched to form a so-called sealing device and are not sealed.

In summary, when the porous sealing device for connecting the vertical flexible barrier system disclosed in CN 102444145B is inserted into an expansion water stop gasket, the expansion water stop gasket cannot be inserted to the end, the sealing cavity cannot be uniformly filled, so that a virtual insertion and a virtual filling are inevitably formed, and the surplus part which is not inserted in place is directly cut off by a constructor, so that a virtual sealing structure is formed in the bottom water storage area, and the sealing and blocking of underground polluted water cannot be realized, and the purpose of reliable sealing cannot be realized.
