Abstract

The utility model relates to a tunnel waterproofing device, in particular to a waterproofing device for pipeline crossing, which comprises a waterproof layer reinforcing layer, an elastic gasket and fastening devices, wherein the elastic gasket is covered on the surface of the outer wall of a pipeline, the waterproof layer reinforcing layer is in a cylindrical shape, and is provided with a flange on one end thereof, the flange is connected with a full-wrapped waterproof layer, and the cylindrical part of the waterproof layer reinforcing layer is sleeved on the elastic gasket, and the elastic gasket, the cylindrical part of the waterproof layer reinforcing layer and the pipeline are tightly pressed and fixed through at least three fastening devices. With the device, the water pressure resistance capacity of the joint between the pipeline and the full-wrapped waterproof layer can reach 0.9MPa, and therefore, the waterproof performance is safe and reliable.

Description

Be used for the water-tight device that pipeline passes through
Technical field
The utility model relates to the tunnel water proofing device, specifically relates to the water-tight device of pipeline crossing full-packaging waterproof layer.
Background technique
Passing through tunnel structure full-packaging waterproof layer place for pipeline in the prior art at present generally adopts the perfusion sealer to satisfy waterproof requirement in both joints.The advantage of perfusion sealer is simple to operate, and is with low cost.But the sealer structure can not be born higher hydraulic pressure, the geological environment of inapplicable high hydraulic pressure.And might occur empty sticking situation between sealer and watertightness barrier, sealer and the pipeline, thereby influenced the integral waterproofing effect of tunnel or connecting passage.
Summary of the invention
The purpose of this utility model is according to above-mentioned the deficiencies in the prior art part, and a kind of water-tight device that pipeline passes through that is used for is provided, and this device improves the water-proof performance of seam crossing by increase watertightness barrier reinforced layer, resilient pad, lock ring device.
The utility model purpose realizes being finished by following technological scheme:
A kind ofly be used for the water-tight device that pipeline passes through, comprise the full-packaging waterproof layer structure and pass through the pipeline of full-packaging waterproof layer structure, it is characterized in that: this device has watertightness barrier reinforced layer, resilient pad and lock ring device, described resilient pad is coated on the pipeline outer wall surface, described watertightness barrier reinforced layer is column, the one end is provided with flange, wherein said flange engages with full-packaging waterproof layer, the stylolitic part of described watertightness barrier reinforced layer is set on the resilient pad, by at least two lock ring devices resilient pad, watertightness barrier reinforced layer stylolitic part and pipeline three is fixed.
Described resilient pad is vulcanized butyl rubber thin slice not.
Described lock ring device quantity is two.
A kind of water-tight device that is used for pipeline crossing full-packaging waterproof layer is characterized in that described lock ring device is a stirrup.
Described full-packaging waterproof layer is identical material with the watertightness barrier reinforced layer.
The flange portion of described watertightness barrier reinforced layer is connected with full-packaging waterproof layer by welding.
The utility model has the advantages that and adopt that pipeline and full-packaging waterproof layer joint hydraulic pressure resistance ability can reach 0.9MPa, make its water-proof performance safe and reliable by this device.
Description of drawings
Accompanying drawing 1 is the utility model embodiment cross-sectional configuration schematic representation;
Accompanying drawing 2 is the utility model embodiment watertightness barrier reinforced layer structural representation;
Accompanying drawing 3 is the utility model embodiment resilient pad structural representation;
Accompanying drawing 4 is the utility model embodiment perspective view.
Embodiment
The utility model feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, so that technician's of the same trade understanding:
Shown in Fig. 1-4, label 1-9 represents respectively: prop up sheath 1, nonwovens buffer layer 2, full-packaging waterproof layer 3, watertightness barrier reinforced layer 4, pass through the stylolitic part 8 of watertightness barrier pipeline 5, lock ring device 6, resilient pad 7, watertightness barrier reinforced layer, the flange portion 9 of watertightness barrier reinforced layer.
Present embodiment is by increase watertightness barrier reinforced layer 4, resilient pad 7 and lock ring device 6, thereby the sealability of raising watertightness barrier 3 and pipeline 5 seam crossings can reach 0.9MPa by above-mentioned waterproof measure hydraulic pressure resistance ability.
As shown in Figure 1 and Figure 4, pipeline 5 passes through tunnel structure, resilient pad 7 is coated on pipeline 5 outer wall surface, and the stylolitic part 8 of watertightness barrier reinforced layer 4 is set on the resilient pad 7, and stylolitic part 8 and pipeline 5 threes with resilient pad 7, watertightness barrier reinforced layer are fixed by two lock ring devices 6.
The watertightness barrier reinforced layer adopts the PVC splash guard in the present embodiment.Conspicuous, can play good sealing effect equally for this device of watertightness barrier of other materials such as ECB.
As shown in Figure 3, resilient pad 7 is devices of tubulose.Material is a vulcanized butyl rubber thin slice not, and performances such as the elasticity of this thin slice, ageing resistance and intensity can satisfy required performance.
As shown in Figure 2, watertightness barrier reinforced layer 4 is column, and the one end is provided with flange.Reinforced layer 4 is selected identical material with full-packaging waterproof layer for use.
Lock ring device 6 is a stirrup in the present embodiment, and its quantity is two, and the quantity of stirrup can increase and decrease according to different geological states and pipe diameter.
