Abstract
The invention relates to a tunnel waterproof device, in particular to a waterproof device in a position where a pipeline passes through a whole-coated waterproof layer. The device is provided with a waterproof layer reinforced layer, an elastic gasket and tightening devices, wherein the elastic gasket is coated on the surface of an outer wall of the pipeline; a flange is arranged at one end of the cylindrical waterproof layer reinforced layer, and is jointed with the whole-coated waterproof layer; the cylindrical part of the waterproof layer reinforced layer is sleeved on the elastic gasket; and the elastic gasket, the cylindrical part of the waterproof layer reinforced layer and the pipeline are compacted and fixed through at least two tightening devices. By adopting the device, hydraulic pressure resistance on the joint position of the pipeline and the whole-coated waterproof layer can reach 0.9MPa, so that water resistance of the jointed position can be safe and reliable.
Description
Technical field
The present invention relates to the tunnel water proofing device, specifically relate 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 objective of the invention is provides a kind of water-tight device that is used for pipeline crossing full-packaging waterproof layer according to above-mentioned the deficiencies in the prior art part, and this device improves the water-proof performance of seam crossing by increase watertightness barrier reinforced layer, resilient pad, lock ring device.
The object of the invention realizes being finished by following technological scheme:
A kind of water-tight device that is used for pipeline crossing full-packaging waterproof layer, 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 the 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 with resilient pad, watertightness barrier reinforced layer stylolitic part and pipeline three are 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.
Advantage of the present invention is to adopt by this device, and pipeline and full-packaging waterproof layer joint hydraulic pressure resistance ability can reach 0.9MPa, make its water-proof performance safe and reliable.
Description of drawings
Accompanying drawing 1 is an embodiment of the invention cross-sectional configuration schematic representation;

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.
