The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of built-in draining waterstop that is used for the construction of tunnel seam is provided.The utility model installation in position is easy, and stagnant water effect is good, also has good draining pressure release ability, and it is simple in structure, easy to use, be convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: the built-in draining waterstop that is used for the construction of tunnel seam, it is characterized in that: comprise banded middle rib, the upper left side of described banded middle rib, upper right side, lower left and lower right are respectively arranged with the upper left wing, the upper right wing, the lower-left wing and the bottom right wing, the described lower-left wing, the upper right wing, the lower-left wing and the bottom right wing all extend along the length direction of banded middle rib, the cross section of described waterstop is " X " shape, and the described upper left wing, the upper right wing, the lower-left wing, the bottom right wing and banded middle rib all adopt elastomeric material to make.
The above-mentioned built-in draining waterstop that is used for the construction of tunnel seam is provided with the drainage cloth between the described upper left wing and the upper right wing.
The above-mentioned built-in draining waterstop that is used for the construction of tunnel seam, the upside of the described upper left wing, the upper right wing, the lower-left wing and the bottom right wing is provided with the sealing rib, and the downside of the described upper left wing, the upper right wing, the lower-left wing and the bottom right wing is provided with down the sealing rib.
The above-mentioned built-in draining waterstop that is used for the construction of tunnel seam, described elastomeric material is an elastomeric material.
The utility model compared with prior art has the following advantages: installation of the present utility model is more convenient, and the position of installing is very accurate, percolating water to construction of tunnel seam place has good sealing effect, and the utility model is provided with drainage channel, by drainage channel the water that leaks out is discharged; And the utility model is also realized multiple obstruction by the last sealing rib and the following sealing rib that are provided with to percolating water, realizes the complete sealing to engineering seam place percolating water.Of the present utility model simple in structure, installation process is convenient easy to operate, and sealing, the draining of construction of tunnel being stitched percolating water have extraordinary effect, have great practical value.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
A kind of built-in draining waterstop that is used for the construction of tunnel seam as shown in Figure 1, comprise banded middle rib 5, the upper left side of described banded middle rib 5, upper right side, lower left and lower right are respectively arranged with the upper left wing 1, the upper right wing 2, the lower-left wing 3 and the bottom right wing 4, the described lower-left wing 1, the upper right wing 2, the lower-left wing 3 and the bottom right wing 4 all extend along the length direction of banded middle rib 5, the cross section of described waterstop is " X " shape, and the described upper left wing 1, the upper right wing 2, the lower-left wing 3, the bottom right wing 4 and banded middle rib 5 all adopt elastomeric material to make, and described elastomeric material is an elastomeric material.The length of this waterstop can be determined according to the arch shaped length of tunnel wall.
When pouring into a mould lining cutting in the tunnel, adopt the method for step pouring, leave constuction joint between each section lining cutting, shrinkage joint and settlement joint, normally three sew up one, abbreviate the engineering seam as, in the engineering seam, this built-in draining waterstop is installed, as shown in Figure 2, push waterstop from banded middle rib 5 one sides of this waterstop and make banded middle rib 5, the upper left wing 1 contacts with termination template 10 with the lower-left wing 3, and the upper left wing 1 and the lower-left wing 3 that paste mutually with termination template 10 are flattened, and the left side of the upper left wing 1 that flattens and the left side of the lower-left wing 3 and banded middle rib 5 overlaps with engineering seam 12, this waterstop is fixed on the termination template 10 with steel nail 11 every a segment distance.During concreting, the upper right wing 2 and the bottom right wing 4 that expose are embedded in the concrete.Behind the stripping, the upper left wing 1 that before had been driven plain and the lower-left wing 3 can recover original shape because of elasticity, and the upper left wing 1 and the lower-left wing 3 will expose.After next section lining cutting was built, this waterstop just was placed in the engineering seam central authorities of institute's shutoff, and formed drainage channel 7 in the side that meets water by the upper left wing 1 of this waterstop and the trigonum between the upper right wing 2.During the work of this waterstop, if underground water flows to waterstop along engineering seam 12, the upper left wing 1 of waterstop and the last trigonum between the upper right wing 2 will stop current mobile along original direction, current under the effect of gravity, along last drainage channel 7 to dirty.If engineering object does not have drainage system, the upper left wing 1 of this waterstop and the upper right wing 2 water blockoff of will going ahead of the rest, if this defence line is broken, the lower-left wing 3 and the bottom right wing 4 of this waterstop will continue shutoff, stitch waterproof for engineering dual assurance is provided.The utility model can accurately installing and locating, the percolating water at engineering seam place is had good stagnant water effect, and can percolating water be discharged by its drainage channel 7, in the application process of reality, obtain good effect.
Be provided with drainage cloth 6 between the described upper left wing 1 and the upper right wing 2.Drainage cloth 6 can filter the water that leaks out, and avoids the impurity in the water that drainage channel 7 is stopped up, thereby influences the operate as normal of waterstop.
The upside of the described upper left wing 1, the upper right wing 2, the lower-left wing 3 and the bottom right wing 4 is provided with sealing rib 8, and the downside of the described upper left wing 1, the upper right wing 2, the lower-left wing 3 and the bottom right wing 4 is provided with down sealing rib 9.By sealing rib 8 and following sealing rib 9 are set, the water that stays along this waterstop edge is carried out multiple obstruction.
The described upper left wing 1, the upper right wing 2, the lower-left wing 3, the bottom right wing 4 and banded middle rib 5 all adopt elastomeric material to make.Utilize the elastomeric material better elastic, and rubber is used more extensive in daily productive life, draw materials when making this waterstop conveniently, and it is cheap, cost of manufacture is low, for the bigger tunnel of length, during the waterstop large usage quantity, adopt the waterstop of this material can save a large amount of costs.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of technical solutions of the utility model.
