Description
Technical field
The utility model relates to a kind of rubber fastening band that is applicable to tunnel and underground construction concrete construction joint, shrinkage joint and settlement joint, buries back sticking type draining rubber fastening band in a kind of standard but especially relate to.
Background technology
The percolating water of tunnel and underground construction mostly occurs on the constuction joint of lining cutting, shrinkage joint and settlement joint (being called for short the engineering seam), and the back sticking type waterstop plays an important role in lining project seam waterproof.Existing back sticking type waterstop has the following disadvantages: drain function or drainability that (1) does not possess behind the lining wall are relatively poor, make behind the lining wall hydraulic pressure big and cause tunnel percolating water easily; (2) the sealing rod material softness on the back side easily strikes the beam in the concreting process and can not bring into play its normal sealing function; Less to the on-way resistance of engineering seam after moulding makes infiltration by lining wall, underground water oozes out along the back side of waterstop easily.
The utility model content
Technical problem to be solved in the utility model is at above-mentioned deficiency of the prior art, buries back sticking type draining rubber fastening band in a kind of standard but provide, its compact conformation, and easy to use, percolation-proof effect is good and Acceptable life is long, and is not yielding.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: but bury back sticking type draining rubber fastening band in a kind of standard, the left wing and the right flank that detour and be arranged on its both sides that comprise the U word shape, above the described upstream face that detours, be provided with and only starch drainage cloth, and between only starching drainage cloth and detouring, form the drainage channel that is connected with the construction drainage system, it is characterized in that: the outside of described left wing and right flank all is connected with vertical section that extends to its back side direction, and be respectively arranged with flat section in a left side that stops underground water infiltration in engineering seam and right flat section, described detouring by described vertical section, left wing, right flank, the flat section in a left side, right flat section and two vertical sections are integral structure.
Described both sides of only starching drainage cloth are bonded in respectively on the upstream face of left wing and right flank.
The utility model compared with prior art has the following advantages: 1, compact conformation, and easy to use.2, the utility model adopts in the standard and buries the back sticking type mounting means, and its percolation-proof effect is good.Its concrete course of work is: when underground water is pooled to waterstop body upstream face, because the flat section in a left side, the perpendicular section in a left side, left wing, detour, right flank, the waterstop body that right perpendicular section and right flat section constitute is fluid-tight rubber material, so underground water might be walked around the left wing that is positioned at the left side of detouring, the upstream face of perpendicular section in a left side and the flat section in a left side, perhaps walk around the right flank that is positioned at the right side of detouring, the upstream face of right perpendicular section and right flat section, and from waterstop body back side enters engineering seam, but this underground water infiltration route resistance is big, and long flow path experimental results show that its water percolating capacity can ignore; On the other hand owing to only starch drainage cloth and have good water permeability, underground water be easy to enter only starch drainage cloth and detour between drainage channel in, and enter in the construction drainage system, so percolation-proof effect of the present utility model is very good by it.3, Acceptable life is long, and is not yielding.The utility model when mounted, engineering is sewn on the left side of the back side that detours, and with left wing's quadrature, decrease distortion so the waterstop body is difficult for being dashed by underground water after installation.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment
As shown in Figure 1, what the utility model comprised the U word shape detours 1 and the left wing 2 and the right flank 3 that are separately positioned on its both sides, above 1 the upstream face of detouring, be provided with and only starch drainage cloth 4, and only starching drainage cloth 4 and the formation drainage channel 9 between 1 that detours, drainage channel 9 communicates with the construction drainage system.The outside of left wing 2 and right flank 3 all is connected with vertical section that extends to its back side direction, and be respectively arranged with flat section 6 in a left side that stops underground water infiltration in engineering seam 11 and right flat section 8 by described vertical section, in the present embodiment, the left side of left wing 2 is connected with to the perpendicular section 5 in the left side that its back side extends, and the bottom of perpendicular section 5 is connected with the flat section 6 in a left side of extending to the left on a left side; Corresponding with it, the right side of right flank 2 is connected with to the perpendicular section 7 in the right side that its back side extends, and the bottom of perpendicular section 7 is connected with the flat section 8 in the right side of extending to the right on the right side.The flat section 6 in a left side, the perpendicular section 5 in a left side, left wing 2, detour 1, right flank 3, right perpendicular section 7 and right flat section 8 be integral structure, and constitute the waterstop body.Wherein, the both sides of only starching drainage cloth 4 are connected on left wing 2 and the right flank 3 with bonding mode, and are positioned at 1 the top of detouring.
Bury back of the body subsides during the utility model is as the criterion and be installed on the needed construction location, as shown in Figure 1, the waterstop body is arranged between left lining cutting section 12 and the right lining cutting section 13, and the engineering that stops underground water to enter between left lining cutting section 12 and the right lining cutting section 13 is stitched in 11.Wherein, left lining cutting section 12 is a cast section earlier, and right lining cutting section 13 is a back cast section.Its concrete work progress is: the formation level 10 the when upstream face of waterstop body is close to the lining concrete construction, and with devices such as module location and support and detour 1 and the waterstop body part on 1 right side of detouring, after the concrete pouring left side lining cutting section 12, take off devices such as described module, pour into a mould right lining cutting section 13, and make engineering seam 11 left side and left wing's 2 quadratures at 1 back side that detours.The utility model is after installing, when underground water is pooled to waterstop body upstream face, owing to be positioned at the flat section 6 of a perpendicular section 5 in left wing 2, a left side and a left side in 1 left side of detouring, and the perpendicular section 7 in right flank 3, the right side and right flat period 8 stop that are positioned at 1 right side of detouring, underground water enters into drainage channel 9 from the drainage cloth 4 of only starching with good water permeability, and enter in the construction drainage system by drainage channel 9 and to discharge, so percolation-proof effect of the present utility model is good, underground water can not enter into engineering seam 11.
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.
