Abstract
The invention relates to a tunnel water proofing method, in particular to a water proofing method while inserting a pipeline into a fully-clad waterproof layer. The method is realized by adding a waterproof layer reinforcing layer, an elastic spacer and tightening devices, wherein, the waterproof layer reinforcing layer takes a column shape and one end of the waterproof layer reinforcing layer is provided with a flange; the waterproof layer reinforcing layer, the elastic spacer and the tightening device are connected by the following steps: cladding an outer wall surface of the pipeline with the elastic spacer, and then sheathing a column-shaped part of the waterproof layer reinforcing layer on the elastic spacer; jointing the flange with the fully-clad waterproof layer; and finally pressing and fixing the elastic spacer, the column-shaped part of the waterproof layer reinforcing layer and the pipeline by at least two tightening devices. The joint between the pipeline and the fully-clad waterproof layer treated by the method can achieve hydraulic pressure resistance up to 0.9MPa, thus causing the waterproofing property to be safe and reliable.
Description
Technical field
The present invention relates to tunnel waterproofing method, specifically relate to the waterproof method 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 method for perfusion sealer in both joints to satisfy waterproof requirement.The advantage of this method is simple to operate, but pouring into sealer can not bear 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 waterproof method that is used for pipeline crossing full-packaging waterproof layer according to above-mentioned the deficiencies in the prior art part, and this method is by setting up connector element, to improve the water-proof performance of seam crossing between pipeline outer wall and full-packaging waterproof layer.
The object of the invention realizes being finished by following technological scheme:
A kind of waterproof method that is used for pipeline crossing full-packaging waterproof layer, comprise tunnel structure and the pipeline that passes through tunnel structure, it is characterized in that this method set up the watertightness barrier reinforced layer, resilient pad, with the lock ring device, wherein the watertightness barrier reinforced layer is column, the one end is provided with flange, and adopt following steps to connect: resilient pad is coated on the pipeline outer wall surface, stylolitic part with the watertightness barrier reinforced layer is set on the resilient pad afterwards, described flange is engaged with full-packaging waterproof layer, use at least two lock ring devices at last resilient pad, the stylolitic part of watertightness barrier reinforced layer and pipeline three are fixed.
Described resilient pad is a vulcanized butyl rubber thin slice not, and the vulcanized butyl rubber thin slice does not play the effect of slight gap between sealing watertightness barrier reinforced layer and the wall-passing pipe.
Described resilient pad can be a long strip, during operation it is wrapped in the pipeline outer wall surface, then piece is engaged, and this resilient pad also can be tubular, during operation it is coated on the pipeline outer wall surface.
Described lock ring device quantity is two, and this device is that stirrup or other can play the device of lock ring effect.
Described watertightness barrier reinforced layer and watertightness barrier adopt identical materials, between the method that can take to weld connect.
Advantage of the present invention is to adopt pipeline and full-packaging waterproof layer joint hydraulic pressure resistance ability after this method is handled can reach 0.9MPa, makes its water-proof performance safe and reliable.
Description of drawings
Accompanying drawing 1 is an embodiment of the invention cross-sectional configuration schematic representation;
Accompanying drawing 2 is an embodiment of the invention watertightness barrier reinforced layer structural representation;
Accompanying drawing 3 is an embodiment of the invention resilient pad structural representation;
Accompanying drawing 4 is an embodiment of the invention perspective view.
Embodiment
Feature of the present invention 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 increasing watertightness barrier reinforced layer 4, resilient pad 7 and lock ring device 6, stylolitic part 8 and pipeline 5 threes with resilient pad 7, watertightness barrier reinforced layer 4 are fixed by lock ring device 6, and the flange portion 9 of watertightness barrier reinforced layer 4 engaged with full-packaging waterproof layer 3, thereby improve the sealability of watertightness barrier 3 and pipeline 5 seam crossings, can reach 0.9MPa by above-mentioned waterproof measure hydraulic pressure resistance ability.
Describe this method in detail below by embodiment.
The watertightness barrier reinforced layer adopts the PVC splash guard in the present embodiment.Conspicuous, can play good sealing effect equally for watertightness barrier this method of other materials such as ECB.
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, and both welding can reach good sealing effect like this.
