Abstract
The utility model discloses a water leakage-proof device during tunnel construction. Waterproof cloth is arranged between a waterproof board and an initial support of a rock stratum base level and is directly adhered on the initial support, the outer layer of the waterproof cloth is a spacer layer, the outer layer of the spacer layer is the waterproof board, and the waterproof board is connected with a secondary lining. The problem of water leakage during the tunnel construction can be effectively solved; due to the waterproof cloth and the spacer layer added between the waterproof board and the initial support, the device can prevent water more effectively compared with the prior art; the spacer layer further plays a part in pressure buffering, i.e. the waterproof board can be protected when the secondary lining is constructed; and the installation size and the structure of the waterproof board are improved, so that the waterproof board can have better effects.
Description
Technical field
The utility model relates to the civil construction technical field, is specifically related to the leakage-proof apparatus in a kind of constructing tunnel.
Background technology
In the constructing tunnel process of construction, resolve waterproof problem, be to guarantee the construction of tunnel quality safety, fundamentally to eliminate tunnel harm and strengthen the important step in tunnel life-span, being applied in of splash guard is in vital status in the constructing tunnel.In the existing tunnel construction, prevent to leak is a technical barrier always, and existing technical scheme generally is that constructing tunnel finishes after the preliminary bracing, needs to lay one deck splash guard before the secondary lining of constructing again, and the skin of splash guard is exactly a secondary lining.When the construction secondary lining, splash guard is easy to be damaged, and the commissure of promptly per two splash guards is easily by drawing crack, and the waterproof effect of this technical scheme is also undesirable, still has the phenomenon of seepage.
The utility model content
The utility model has overcome the deficiencies in the prior art, provide a kind of in constructing tunnel waterproof effect good, and in construction works, be not easy to damage the leakage-proof apparatus of splash guard.
For solving above-mentioned technical problem, the utility model by the following technical solutions:
Leakage-proof apparatus in a kind of constructing tunnel, comprise splash guard, between per two splash guards by being welded together, be fixed in the preliminary bracing of rock stratum basal plane in tunnel by steel nail again, be provided with canvas cloth between the preliminary bracing of splash guard and rock stratum basal plane, described canvas cloth directly is fitted in the preliminary bracing of rock stratum basal plane, and the skin of canvas cloth is a spacer layer, the skin of spacer layer is a splash guard, and described splash guard is connected with secondary lining again.
Further technical scheme is that described spacer layer is plastic plate or asbestos manufacturing.
Further technical scheme is that described per two splash guard edge fit places should reserve the welding surplus that is no less than 20 centimetres again, and the weld width of per two splash guards is 10-20 centimetre.
Compared with prior art, the beneficial effects of the utility model are:
By the leakage-proof apparatus in the utility model constructing tunnel, can solve the problem of leaking in the constructing tunnel effectively, canvas cloth that between splash guard and preliminary bracing, increases and spacer layer, relatively prior art can more effective waterproof, spacer layer has also played the effect of compensator or trimmer pressure, promptly when the casting secondary lining, can avoid damaging splash guard, the utility model has also been made improvement on splash guard installation dimension, structure, can make splash guard bring into play better effect.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:
The 1-preliminary bracing, 2-canvas cloth, 3-spacer layer, 4-splash guard, 5-secondary lining.
The specific embodiment
Below in conjunction with embodiment the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment
As shown in Figure 1, the leakage-proof apparatus in a kind of constructing tunnel comprises splash guard 4, and by being welded together, wherein the edge fit place should reserve the welding surplus that is no less than 20 centimetres between per two splash guards 4, and weld width is 10-20 centimetre.The skin of splash guard 4 is secondary linings 5, be provided with canvas cloth 2 between the preliminary bracing 1 of splash guard 4 and rock stratum basal plane, described canvas cloth 2 directly is fitted in the preliminary bracing 1 of rock stratum basal plane, the skin of canvas cloth 2 is spacer layers 3, the skin of spacer layer 3 is splash guards 4, splash guard 4 is fixed in the preliminary bracing 1 of rock stratum basal plane in tunnel by steel nail again, cast secondary lining 5 on the outer layer surface of described splash guard 4 again, be that above-mentioned splash guard 4 is connected with secondary lining 5, the material that this dress spacer layer 3 is chosen is a plastic plate.
Certainly this device Intermediate gasket layer 3 is as if choosing asbestos or other has the bedding and padding of identical compensator or trimmer pressure effect, and the position at other position is identical with above description, promptly no longer is repeated in this description in the present embodiment.
In sum, just can realize the utility model preferably.
Claims (4)
1. the leakage-proof apparatus in the constructing tunnel, comprise splash guard (4), between per two splash guards (4) by being welded together, be fixed in the preliminary bracing (1) of rock stratum basal plane in tunnel by steel nail again, the skin of splash guard (4) is secondary lining (5), it is characterized in that: be provided with canvas cloth (2) between the preliminary bracing (1) of splash guard (4) and rock stratum basal plane, described canvas cloth (2) directly is fitted in the preliminary bracing (1) of rock stratum basal plane, the skin of canvas cloth (2) is spacer layer (3), the skin of spacer layer (3) is splash guard (4), and described splash guard (4) is connected with secondary lining (5) again.
