Description
Technical field
The utility model establishes water-stopping structure after relating to one, is applicable to subterranean tunnel construction.
Background technology
Along with country is to the demand of water power clean energy resource, a large amount of high dams need be built, a large amount of buried Large Underground tunnel built by corresponding need, comprise access tunnel, water-conveyance tunnel etc., containing pressure and non-pressure tunnel, need by geological conditions and structure design, dependency structure needs parting successively to arrange and distortion needs with satisfied construction, structure has waterproof and the requirement that blocks water simultaneously, sealing material need be arranged close this parting place, generally adopt the mode of embedded water stop material at present, during construction, first phase sealing material pre-plugged is entered first phase structure, when the second stage of structure construction, the second stage of sealing material is imbedded, position and specific requirement that clear and definite sealing material buries underground need be shifted to an earlier date, and sealing material needs safe protection until the construction of the second stage of structure completes.In addition, by the impact of structure design change and the extraneous factor such as underground water, first phase sealing material is failed pre-buried in advance, or first phase sealing material pre-buried after, the second stage of structure construction in time causes sealing material impaired, thus forfeiture waterproof and water stop function.
Utility model content
Technical problem to be solved in the utility model is: a kind of easy construction is provided and do not affect by work progress establish water-stopping structure afterwards.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: after establish water-stopping structure, comprise first phase structure, the second stage of structure, first phase structure end thereon surface is provided with the first groove, water-swellable material water-proof material is provided with in first groove, first phase structure end thereon surface is fixedly installed the first seal plate, and the first groove covers by the first seal plate completely; Second phase, structure front end was provided with the second groove in surface thereon, and be provided with water-swellable material water-proof material in the second groove, the second stage of structure front end thereon surface is fixedly installed the second seal plate, and the second groove covers by the second seal plate completely; First seal plate, the second seal plate are connected by distortion termination, and the parting place between first phase structure, the second stage of structure is located in distortion termination.
Further: first phase structure is fixedly connected with by fastening devices with the first seal plate, and fastening devices comprises expansion bolt, backing plate is provided with between the nut of expansion bolt and the first seal plate; Second phase, structure was fixedly connected with by fastening devices with the second seal plate, and fastening devices comprises expansion bolt, is provided with backing plate between the nut of expansion bolt and the second seal plate.
Further: the first groove is filled by water-swellable material water-proof material completely; Second groove is filled by water-swellable material water-proof material completely.
Further: between first phase structure upper surface and the first seal plate soffit, be provided with surface layer elastomeric material; Surface layer elastomeric material is provided with between second phase structure upper surface and the second seal plate soffit.
The beneficial effects of the utility model are: after first phase structure, the second stage of structure have all been constructed, then arrange water-stopping structure, do not affect, easy construction by work progress, and structure is simple, and reliability is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1-first phase structure, 11-first groove, 2-second phase structure, 21-second groove, 3-water-swellable material water-proof material, 4-first seal plate, 5-second seal plate, 6-are out of shape termination, 7-fastening devices.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises first phase structure 1, the second stage of structure 2, first phase structure 1 end thereon surface is provided with the first groove 11, water-swellable material water-proof material 3 is provided with in first groove 11, first phase structure 1 end thereon surface is fixedly installed the first seal plate 4, first seal plate 4 and is covered completely by first groove 11; Second phase structure 2 front end is provided with in the second groove 21, second groove 21 and is provided with water-swellable material water-proof material 3 in surface thereon, and the second stage of structure 2 front end thereon surface is fixedly installed the second seal plate 5, second seal plate 5 and is covered completely by second groove 21; First seal plate 4, second seal plate 5 is connected by distortion termination 6, and the parting place between first phase structure 1, the second stage of structure 2 is located in distortion termination 6.
Water-swellable material water-proof material 3 can need to select corresponding expansion rate according to scene; The material of the first seal plate 4, second seal plate 5 should consider the demands such as durability, pull resistance, extensibility, flexing resistance, can adopt copper or copper alloy; Distortion termination 6 form can be selected according to the requirement of degree of deformation, preferably adopts Ω shape.
Preferably, first phase structure 1 is fixedly connected with by fastening devices 7 with the first seal plate 4, and fastening devices 7 comprises expansion bolt, is provided with backing plate between the nut of expansion bolt and the first seal plate 4; Second phase, structure 2 was fixedly connected with by fastening devices 7 with the second seal plate 5, and fastening devices 7 comprises expansion bolt, is provided with backing plate between the nut of expansion bolt and the second seal plate 5.
Preferably, the first groove 11 is filled by water-swellable material water-proof material 3 completely; Second groove 21 is filled by water-swellable material water-proof material 3 completely.
Preferably, surface layer elastomeric material is provided with between first phase structure 1 upper surface and the first seal plate 4 soffit; Surface layer elastomeric material is provided with between second phase structure 2 upper surface and the second seal plate 5 soffit.Surface layer elastomeric material plays first phase and to block water object; After first phase blocks water and lost efficacy, by the characteristic of water-swellable material water-proof material 3 water-swellable, the further gap of compression seal plate and structural plane, reaching the second phase blocks water object.
