Abstract
The utility model relates to a waterproof device, in particular to a waterproof structure for a tunnel. The waterproof structure for the tunnel comprises a geotechnical cloth layer arranged on the surface of concrete. A plurality of hot melting liners are arranged on the outer side of the geotechnical cloth layer. A waterproof board covers the outer sides of the hot melting liners and the geotechnical cloth layer. The waterproof board is formed by a plurality of boards which are connected with each other in a welded-overlap-joint mode in sequence. Sealing air channels are arranged among welding joints of overlap connections of the boards. The waterproof structure for the tunnel has the advantages of being capable of being fully combined and firmly attached to the surface of the concrete, reasonable in arrangement, and simple in operation, and guaranteeing good water waterproof performance.
Description
Technical field
The utility model relates to a kind of water-tight device, particularly a kind of tunnel waterproof construction.
Background technology
Along with the fast development of modern railways, highway, especially in the mountain area, the tunnel, not only saves time back and forth between two places close to straight line, and is also safer, become more and more common traffic ingredient.In the constructing tunnel process, resolve tunnel water proofing, draining, just can guarantee Inspection of Tunnel Quality, fundamentally eliminate tunnel safety hidden danger, increase tunnel application life.At present tunnel water proofing is mainly first directly to lay nonwoven or splash guard in country rock, preliminary bracing, and this laying difficulty is large, effect is unsatisfactory, easily causes the waterproof imprecision and leaks or seep water.
The utility model content
Goal of the invention of the present utility model is: the problem for prior art exists, a kind of tunnel waterproof construction is provided, and this waterproof construction laying is firm, easy to operate, waterproof effect is good.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of tunnel waterproof construction comprises the geotechnological layer of cloth that is located at concrete surface, is provided with some hot melt liners outside described geotechnological layer of cloth, and described splash guard is covered in the outside of described hot melt liner and geotechnological layer of cloth.
Preferably, described splash guard is welded to each other successively overlap joint by some blocks of plates and forms, and the width of described lap-joint plate is more than or equal to 15cm.
Preferably, be provided with the sealing air road between the weld seam of described splash guard lap-joint.
Preferably, described splash guard is at described hot melt liner place's formation bulge-structure adaptive with described hot melt pad profile.
Preferably, described splash guard is for being welded in the described hot melt liner outside.
Preferably, the 1.0 ~ 2.0m that staggers of deformation joint, the constuction joint in described splash guard lap-joint and described concrete.
Preferably, it is surperficial that described hot melt liner is fixed in described geotechnological layer of cloth by nailing, packing ring, and described nailing embeds in described concrete.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
A kind of tunnel described in the utility model waterproof construction, geotechnological layer of cloth, some hot melt liners are set respectively outside concrete, and with nailing, the hot melt liner is fixed on geotechnological layer of cloth and nailing embedding concrete, then in hot melt liner surface soldered, splash guard is arranged, geotechnological layer of cloth is laid and compressed to splash guard simultaneously, and splash guard is formed by some plate welded lap.This waterproof construction can be fully in conjunction with and firmly be close to concrete surface, rationally distributed, simple to operate, guaranteed good water resistance.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1, a kind of tunnel waterproof construction comprises the geotechnological layer of cloth 2 that is located at concrete 1 surface, and described geotechnological layer of cloth 2 outsides are provided with some hot melt liners 3, and described splash guard 6 is covered in the outside of described hot melt liner 3 and geotechnological layer of cloth 2.
Wherein, when laying geotextiles layer 2 on concrete 1, at first with simple and easy operation platform, the geotechnological layer of cloth 2 of single width is fixed to the precalculated position, then with hot melt liner 3 and nailing 4, packing ring 5, geotechnological layer of cloth 2 is fixed on sprayed mortar 1; Special-purpose hot melt liner 3 and nailing 4 are by quincuncial arrangement, arch spacing 0.5-0.7m, abutment wall spacing 1.0-1.2m.Geotechnique's layer of cloth 2 is laid and is wanted the degree of tightness appropriateness, makes it to be close to sprayed mortar 1 surface, and tension easily is torn, and the mistake pine affects splash guard 6 and hangs, and between geotechnological layer of cloth 2 width, lap width is greater than 10cm.Splash guard 6 is welded on described hot melt liner 3 surfaces, forms domes when splash guard 6 is laid on geotechnological layer of cloth 2, hot melt liner 3.
Want degree of tightness appropriateness when splash guard 6 is laid on geotechnological layer of cloth 2, hot melt liner 3 in addition and leave surplus, making it fully to engage and be close to sprayed mortar 1 surface with geotechnological layer of cloth 2.Prevent too tight or too loose and splash guard 6 breakage that is squeezed may form the people for the retaining point.6 lap-joints 7 of splash guard should be advisable with the waterproof weak links such as deformation joint, the constuction joint 1.0～2.0m that staggers.
As shown in Figure 2, splash guard 6 is welded to each other overlap joint by some blocks of plates and forms, and in order to guarantee splash guard 6 bond strengths, its two width splash guard lap-joint 7 width are more than or equal to 15cm; Also be provided with sealing air road 9 between the weld seam 8 of splash guard lap-joint 7, the air channel 9 that is provided with is in order to check the weldquality of splash guard lap-joint 7; Its method of inspection is to utilize aeration to check the sealing of weld seam 8, being about to entry needle and pressure meter joins, with inflator, sealing air road 9 is inflated, when reaching 0.25Mpa, pressure meter stops inflation, keep 15min, if air channel 9 pressure drops in 10%, illustrate that weld seam 8 is qualified, as too fast in pressure drop, illustrate that weld seam 8 is not tight; Spread upon on weld seam 8 with suds again, the repair welding again of alveolate place, until air tight, guarantee the good water resistance of splash guard 6.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
