Substitute the cover structure of general steel plate or stainless steel plate production.Liner sandwich layer is pasted onto air cushion by adhesives such as epoxy resin
The concrete structural surface of formula surge-chamber.The suitable rubber of several model specifications is arranged in appropriate location on nylon cloth or rubber slab
Duckbill valve, rubber duck-bill valve are pasted closely, securely using the adhesives such as epoxy resin and nylon cloth or rubber slab, and effect is:
When the pressure in air cushion type pressure balance chamber is higher than liner sandwich layer outside external water pressure, the indoor gas of pressure regulation and water body are prevented inside
Lining core layer External leakage；When the pressure in air cushion type pressure balance chamber is lower than external water pressure outside liner sandwich layer, allow liner sandwich layer
External gas and water body, toward cover internal leakage, balances surge-chamber internal and external pressure difference by unidirectional rubber duck-bill valve.
Using the utility model --- the novel cover obturator of air cushion type pressure balance chamber can fundamentally solve ordinary steel
The generally existing production of the cover structure that plate or stainless steel plate make, mounting process complexity, long construction period and technical requirements are high
The problems such as, while operation, maintenance workload are reduced, so that the project cost and O&M cost of air cushion type pressure balance chamber be effectively reduced.
Detailed description of the invention
Fig. 1 is the novel cover obturator diagrammatic cross-section of the utility model air cushion type pressure balance chamber；
Wherein, 1 is liner sandwich layer；2 be rubber duck-bill valve.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
Embodiment 1
As shown in Figure 1, a kind of cover structure of air cushion type pressure balance chamber of the utility model, using the endurance of appropriate specification,
The liner sandwich layer 1 of anti-aging, tear-proof high-strength nylon cloth production, to substitute conventional general steel plate or stainless steel plate production
Liner core structure.
Liner sandwich layer 1 is applied on nylon cloth or rubber slab by adhesives, adhesives such as epoxy resin with a bulk, from
It is upper and under be pasted onto the concrete surface of air cushion type pressure balance chamber by width, concrete surface need to pre-process it is smooth, clean, above and below
There must be certain amount of lap between width nylon cloth or rubber slab and paste closely knit.On the liner sandwich layer 1 of nylon cloth production, appropriate position
Install the suitable rubber duck-bill valve 2 of several model specifications.
Embodiment 2
This embodiment the difference from embodiment 1 is that, the liner sandwich layer use rubber slab.
Further preferred, the rubber duck-bill of cover structure technology scheme as a kind of air cushion type pressure balance chamber of the utility model
Valve 2 is pasted close, secured using the adhesives such as epoxy resin and nylon cloth or rubber slab.
2 role of rubber duck-bill valve is unidirectional valve action, i.e., when the pressure in air cushion type pressure balance chamber is higher than interior lining core
When 1 external pressure of layer, the indoor gas of pressure regulation and water body 1 External leakage of lining core layer inside are prevented；When in air cushion type pressure balance chamber
When pressure is lower than 1 external pressure of liner sandwich layer, gas and water body outside liner sandwich layer 1 is allowed to pass through rubber duck-bill valve 2 inside
1 internal leakage of lining core layer balances surge-chamber internal and external pressure difference.
Setting position, specification and the quantity of rubber duck-bill valve 2, need to be in conjunction with the Permeable characteristic of country rock outside air cushion type pressure balance chamber
It is determined with the inside and outside pressure balancing structure design of concrete.
Undeclared part involved in the utility model is same as the prior art or is realized using the prior art.Liner
1 external structure of sandwich layer is reinforced concrete structure, then external is country rock body.
