Description
Technical field
The utility model relates to a kind of shrinkage joint water-stopping structure spare, and it belongs to aqueduct, channel, pipeline, building such as water-conveyance tunnel body shrinkage joint antiseepage member class.
Background technology
Aqueduct, channel, pipeline; Building bodies such as water-conveyance tunnel are to carry ditch water flow to cross over the water transfer facility at rivers and canals, road, a stretch of flatland in a hilly area, the mouth of a valley etc.; Except that being used to carry water in a canal to carry out field irrigation, urban domestic water, industrial water use, stride the water delivery of basin, but the usefulness of water supply and draining and water conservancy diversion also.Along with aqueduct, channel, pipeline, water-conveyance tunnel etc. are built body employing shell groove, thin wall construction is increasing, and the joint between member, seam and cell wall leakproof, antiseepage problem also increase thereupon.Oneself builds aqueduct, channel, pipeline at present, the more serious leakage problems of building body ubiquity such as water-conveyance tunnel, and saying of " ten grooves nine leak " that exists in the industry, " ten channels nine decreasing " is exactly typical case's description of this phenomenon.Have data to show, it is to cause aqueduct, channel, pipeline that joint seals such as various shrinkage joint, settlement joint lost efficacy, the first cause of building such as water-conveyance tunnel body seepage.Aqueduct, channel, pipeline, the shrinkage joint of building bodies such as water-conveyance tunnel leaks, and directly has influence on safe operation, causes the surprising waste of irrigation water resource simultaneously, influences the irrigated area drought-relief and protection of the harvest.Moreover, from the shrinkage joint, infiltrating aqueduct, channel, pipeline, the moisture in the matrix of building bodies such as water-conveyance tunnel can make matrix be in saturation state, causes to collapse, destroy.At north cold area, also can take place owing to the matrix frost heave causes frost heaving failure.For this reason, the shrinkage joint has leaked into the main working tasks of seepage control project.Consider the importance of shrinkage joint sealing; The research and development stagnant water effect is good, the shrinkage joint water-stopping structure spare of easy construction; To guaranteeing aqueduct, channel, pipeline; The safe handling of building such as water-conveyance tunnel body prolongs aqueduct, channel, pipeline, and building bodies such as water-conveyance tunnel have great importance application life.
In the prior art, aqueduct, channel, pipeline, the sealing at building body shrinkage joint such as water-conveyance tunnel adopt mostly and carry out simple filling like pitch class, rubber sealing rod class material; Exist durability, resistant of high or low temperature, elastic performance, whole adhesive property and the relatively poor shortcoming of intensity, and construction technology is loaded down with trivial details, can not well satisfies aqueduct, channel, pipeline; The shrinkage joint sealing performance requirement of building such as water-conveyance tunnel body, comparatively advanced aqueduct, channel, pipeline, building body shrinkage joint waterstop members such as water-conveyance tunnel are that CN201020658946.4 is disclosed; Accompanying drawing 1 is its structural representation; Such shown in accompanying drawing 1, this U-shaped shrinkage joint composite water stop comprises the rubber fastening band main body; It is characterized in that vertically having U type structure, have glue-line below the rubber fastening band main body at the middle part of rubber fastening band main body.The problem that the disclosed this U-shaped of CN201020658946.4 shrinkage joint composite water stop exists is that the U-shaped space in use holds foreign material easily; At aqueduct, channel, pipeline; In the process of building such as water-conveyance tunnel body shrinkage joint distortion; The foreign material that are contained in the U-shaped space cause the breakage of U-shaped portion easily, because this one seepage control measure only, in case the breakage of U-shaped portion promptly causes seepage for this reason.Moreover, in use, be out of shape bigger U-shaped portion and form sharp-pointed folding line easily; It is finally damaged that As time goes on folding line slowly forms bigger crackle; Moreover the two ends of U-shaped portion are mainly bonding by glueing joint with the aqueduct body, and reliability is not high, and these all have further improved necessity.
Summary of the invention
The purpose of the utility model is to provide a kind of shrinkage joint water-stopping structure spare, to overcome the problem that prior art exists.
A kind of shrinkage joint water-stopping structure spare of the utility model; Comprise the U-shaped waterstop; Said U-shaped waterstop comprises the U-shaped portion that is arranged in the shrinkage joint in use, and is fitted in the end on the building substrate of both sides, shrinkage joint in use respectively, it is characterized in that also comprising that level seals; Said level is sealed on the aperture position that is formed on U-shaped portion, and is connected as one admittedly with the end of U-shaped waterstop.
This shrinkage joint water-stopping structure spare of the utility model; Because on the aperture position of the U-shaped portion of U-shaped waterstop, being provided with level seals; Can prevent effectively on the one hand that foreign material from getting into the space that U-shaped portion limits, thereby effectively prevent the damage that foreign material possibly cause U-shaped portion that the end that the what is more important level is sealed with the U-shaped waterstop has constituted the first road antiseepage barrier together; And U-shaped portion has constituted the second road antiseepage barrier, has obviously promoted the antiseepage level at shrinkage joint.
As further improvement, said U-shaped portion and level are sealed in the space of qualification and are provided with a flexible cylinder, and in the flexible process in shrinkage joint, flexible cylinder will limit the deformation form of U-shaped portion, can effectively prevent the sharp-pointed folding line of formation in deformation process like this.
As further improvement, also comprise pressing plate, said pressing plate is arranged on two ends of U-shaped waterstop, and connects firmly through bolt and building substrate and to connect, and can further promote the watertightness of end like this.Further improvement as aforementioned improved; Be situated between between two ends of said U-shaped waterstop and building substrate and be provided with sealing mat; Being situated between between building substrate and sealing mat and between two ends of sealing mat and U-shaped waterstop simultaneously is provided with adhesive-layer, with further lifting watertightness.
As further improving, said pressing plate is provided with opening and is positioned at the horizontal line of rabbet joint by U-shaped portion one side, also comprises a guard shield, and said guard shield is plugged in the said horizontal line of rabbet joint.Can further seal like this protection is provided, prevent to damage level.
In sum, the purpose of the utility model is achieved.
