Description
Technical field
The utility model relates to a kind of water-stopping structure, is specifically related to a kind ofly be used to prevent that the seam of underground water-supply-pipe from the comprehensive water-stopping structure pattern of two-way drainage taking place.
Background technology
In conveyance structure, there is a large amount of buildings to belong to underground structure or unenclosed construction, comprise inverted-siphon, pass through dyke, pass through ground culvert, pipe laying of means of transportation etc., traditional sealing mode generally is to imbed the rubber fastening band of typing or copper sheet sealing or both to have in the concrete of the both sides of seam crossing, filling oil immersion plank in the seam of structural joint.The water-stopping structure of this form can play the sealing effect, but because the length of alignment error, first inlet part in the work progress is inaccurate, the variation of interior external load and along with the factors such as lengthening of running time, the aging phenomenon of rubber sealing is general, reduced the effect of sealing, increased the leak danger of building in the water delivery process, and entail dangers to is to the safety of monolithic stability and institute's crossing facility of conveyance structure, the copper sheet sealing also exist produce owing to the building displacement and concrete between cracking or burst apart, influence stagnant water effect.
The utility model content
The technical problems to be solved in the utility model provides that a kind of stagnant water effect is good, the water-stopping structure of construction and concrete water transmission pipe easy to maintenance.
In order to solve the problems of the technologies described above, the utility model is by the following technical solutions: a kind of water-stopping structure of concrete water transmission pipe, form seam between the adjacent two joint concrete water transmission pipes, post the seal plate perpendicular on the flow-passing surface inwall of described seam crossing with seam, be provided with joint filling board in the seam, the peripheral sealing of seam seals with hydro-expansive rubber, also is tightly connected by the waterstop of imbedding between the described adjacent two joint concrete water transmission pipes.
Preferably, the end of described each joint concrete water transmission pipe is provided with the tooth bank of outside protrusion.
Preferably, the outside of described hydro-expansive rubber also is provided with the backfill compacting clay.
Preferably, described seal plate is the rubber seal plate.
Preferably, described joint filling board is the high pressure closed-cell foamed plastics plate.
The beneficial effects of the utility model are embodied in: water-stopping structure of the present utility model, for concrete structure tube coupling type conveyance structure, both stoped leaking outside of interior water, prevent water loss, guarantee building safety, prevented that again outer water from infiltrating, fundamentally eliminated building outside fill material and entered the danger that water transport channel causes outer effluent soil seepage failure by structural joint; Because there is the backfill compacting clay in the outside, peripheral sealing has water-swellable material, there is the flush type waterstop inside, the overcurrent inwall is striden seam formula seal plate, has formed the Alliance Defense system, has played best stagnant water effect, delayed the aging progress of inner sealing, no matter the rubber seal plate of obedient formula constructs or routine servicing simultaneously, and all very convenient, quality is controlled easily.The utility model water-stopping structure scope of application is wide, and operational effect is good.

The specific embodiment
As shown in Figure 1 and Figure 2, form seam between the adjacent two joint concrete water transmission pipes 2, water-stopping structure of the present utility model is to post the seal plate 1 perpendicular with seam on the inwall of described seam crossing, seal plate 1 adopts high-strength adhesive to be close in the concrete pit of reservation for striding seam formula rubber seal plate.Fill joint filling board 6 in seam, joint filling board 6 adopts the high pressure closed-cell foamed plastics plate.The peripheral sealing of seam seals with hydro-expansive rubber 5, when concreting, imbed inner typing waterstop 3 between the adjacent two joint concrete water transmission pipes, it can be the rubber sealing, also can be the copper sheet sealing, be tightly connected that waterstop 3 still is a flexible structure with realization, can be the same with traditional waterstop, the distortion of commensurate structure in the regulation and stipulation scope.The outside of concrete water transfer tube seam, promptly the outside of hydro-expansive rubber 5 also is provided with backfill compacting clay 4.
As shown in Figure 3, Figure 4, another kind of embodiment of the present utility model is in the end of each joint water-supply-pipe, just in the seam areas of concrete water transmission pipe, is provided with the tooth bank 21 of outside protrusion.All the other structures are identical with first kind of embodiment.
Above-mentioned concrete water transmission pipe 2 can be the pipe, square tube of sealing etc., also can be uncovered channel pipe, so long as the more piece concrete water transmission pipe is stitched together, just can use water-stopping structure of the present utility model.
The utility model is on the basis of summing up traditional sealing mode pluses and minuses, following two improvement of main proposition: first, with pointing by the oil immersion plank change that modulus of elasticity is little into, elastic deformation is big, adapt to that boundary profile is various, superior performance, high pressure closed-cell foamed plastics plate that ageing resistace is strong, its thickness can be grasped flexibly according to the parting size of different structure; The second, in the inside typing waterstop of in keeping seam, imbedding in the concrete of both sides, stride the seam place at the inwall flow-passing surface and set up transverse joint plate formula rubber sealing one, lay around the whole cross-section of river, can play better anti-seepage effect.Application of practical project shows that this kind water-stopping structure stagnant water effect is good, has reduced the maintenance workload of runtime.
The utility model adopts different sealing synergy, in conjunction with outside impervious material (hydro-expansive rubber 5), water entered structural joint in inboard board-like sealing (seal plate 1) prevented, the infiltration that middle typing waterstop 3 can prevent to enter in the seam continues outflow, stops the underground water in the exterior circumferential geotechnical body to enter underground structure simultaneously.The impervious material in the outside forms the first line of defence that underground water enters underground structure, forms simultaneously to stop underground structure upstream and downstream side current along the concentrated leakage passage that underground structure contact face forms, and guarantees the antiseepage safety and the resistance to overturning of underground structure.Adopt the utility model, when water delivery engineering passes through dyke, river course, means of transportation, other building, can satisfy the antiseep requirement, operation result shows that the utility model water-stopping structure uses face and adapt to geographic coverage wide, and construction is simple, sealing is firm, and material is obtained easily.
Several sealing patterns are combined, and bring into play function separately, unite the sealing effect of playing.Interior water exosmoses and is at first stoped by the rubber seal plate 1 on the inwall, a small amount of water that infiltrates is stoped by the waterstop 3 that is embedded in the concrete, more a spot of infiltration is stoped by the hydro-expansive rubber 5 that seals in exit, the structural joint outside, has thoroughly blocked interior water and has leaked outside.On the other hand, outer water enters at first by the backfill compacting clay 4 of circumferential weld and stops, and a small amount of infiltration is then stoped by the hydro-expansive rubber 5 of sealing, as still has a small amount of infiltration to enter structural joint can be stoped by inner waterstop 3, play thorough sealing effect.
The utility model can be applied in inverted-siphon, aqueduct, passes through the ground culvert in dyke and river course etc., pass through in the middle of the hydraulic structure concrete structures such as water culvert, underground water storage facility excessively of means of transportation.
