Abstract
The utility model discloses an inflatable double-film water-proof pressure box. The box mainly comprises a box body (1), supports (2), a cover plate (3), a rigidity transfer film (4), a stressed film (5), a coil (6), a steel string (7), seal rings (8) , an inflatable inflating valve (9) and a wire (10). At least two seal rings (8) are arranged in the box body (1), the stressed film (5) is arranged on the surface of the box body (1), the rigidity transfer film (4) is arranged outside the stressed film (5), the seal rings (8) are arranged between the rigidity transfer film (4) and the stressed film (5), the two axisymmetric supports (2) are arranged in the box body (1), the two supports (2) are connected by the steel string (7), the coil (6) is arranged below the center of the steel string (7), the wire (10) is connected outside the coil (6), the other end of the wire (10) is connected with the box body (1), the inflatable inflating valve (9) is arranged on the cover plate (3) of the box body (1), and the seal rings (8) are respectively arranged at the two sides of the inflatable inflating valve (9). The inflatable double-film water-proof pressure box has the beneficial effects of good water-proof and seal performances, simple structure and stable test.
Description
Technical field
The utility model relates to the waterproofing pressure box of the stress test of a kind of all kinds of soil bodys applicable to Geotechnical Engineering, rock mass etc.
Background technology
Be used to test the double mode pressure cell of the soil body, rock mass, a Lycopodium chinense Christ prose style free from parallelism in use owing to himself structure and sealing property problem, water can infiltrate box body inside from sealing the inner slit of poor position or lead under big hydraulic action, causes pressure cell to lose efficacy.Novel double mode waterproofing pressure box can be filled out a certain amount of pressure air that has by dashing according to on-site actual situations, accomplishes good insulated enclosure.
The utility model content
The technical problems to be solved in the utility model provides a kind of pressure test that is applicable under the complex geological condition rock upper body under the big situation of hydraulic pressure especially.
Major technique characteristics of the present utility model are: mainly by box body, support, cover plate, rigidity power transmission film, stressed film, coil, string wire, O-ring seal, the inflatable type valve cock, lead constitutes, at least plural O-ring seal is set in the box body, its box body surface is provided with stressed film, stressed film is provided with rigidity power transmission film outward, be provided with O-ring seal between rigidity power transmission film and the stressed film, be provided with in the box body about axisymmetric two supports, connect with a string wire between the two stands, the below, center of string wire is provided with a coil, the outer lead that connects of coil, the lead other end links to each other with box body, one inflatable type valve cock is set on the cover plate of box body, and inflatable type valve cock both sides respectively are provided with an O-ring seal.
Major technique characteristics of the present utility model also are: box body increases O-ring seal with the lead joint
The beneficial effects of the utility model are: the waterproof sealing performance is good, and is simple in structure, stable testing.
