Description
Technical field
The present invention relates to underground engineering field, one kind of processing is overlapped primarily directed to Macromolecular self-adhesive membrane waterproof roll
Measure, particularly with from mining method construction engineering of the coiled material as exterior waterproof coating.
Background technology
Building is project of vital and lasting importance, and architectural engineering seeks to waterproof, protection against the tide in addition to requiring firmly.In the last few years, it is national
The upsurge of especially big and medium-sized cities underground space development is risen one after another, and civil buildings, public transport are all wanting space to underground, and
Scale is increasing, but the thing followed is highlighting for leakage problems, and the scope of seepage is extensively, big harm is that we are difficult
With the imagination.It data show, the average percolation ratio in national house is 65%, and the percolation ratio of hypogee is even more to exceed
80%.The appearance of leakage problems is not just constructed, material the problem of, the applicability of selection is also to cause a weight of later stage seepage
Point, the waterproof sheet material channeling water problem commonly used particularly with Mining Method engineering, never from basic solution.Adhesive polymer
Glued membrane waterproof roll can form integral waterproof material as a kind of with rear pouring concrete, with excellent leakage-proof performance,
But overlapped when being constructed due to it using mull technique, can not ensure to overlap matter in complex environment and in the environment of thering is underground water to disturb
Amount, although after it can form one with rear pouring concrete, but its overlapping part opens, infiltration directly affects coiled material and concrete
Later stage seepage is caused with reference to the pouring quality of even influence concrete, this phenomenon is especially apparent in Mining Method engineering.
The content of the invention
It is an object of the invention to provide Macromolecular self-adhesive membrane waterproof roll welded lap structure and construction method, to solve
By the processing to glue-line, make coiled material can be with welded lap, and seal detection can be carried out to overlap edge, overlap joint is firm, can
Lean on, the technical problem such as strong adaptability.
In order to realize foregoing invention purpose, the technical solution adopted in the present invention is as follows：
Macromolecular self-adhesive membrane waterproof roll welded lap structure, including：Two width coiled materials (2), double weld seams of overlap edge
(3) reserved cavity (4) and covering, between double weld seams in overlap edge is bonded in the sealant tape above overlapping part
(1)；The coiled material at the scrap (bridge) position is the structure for removing adhesive layer.
Macromolecular self-adhesive membrane waterproof roll welded lap construction method, comprises the following steps：
Step one：Two width Macromolecular self-adhesive membrane waterproof rolls (2) are in place；
Step 2：The self-adhesive glue layer of coiled material lapping edge position is removed by special equipment, exposes basic unit's sheet material；
Step 3：The double weld seams (3) of overlap edge that two width coiled materials are removed into glue-line by welding machine are overlapped；
Step 4：Welded seal quality is detected by cavity (4) reserved in the middle part of double weld seams；
Step 5：Overlap edge is covered by sealant tape (1), it is respectively provided with self-adhesive film coiled material with both sides coiled material
Characteristic.
By injecting air in reserved cavity, pressure of satisfying a period of time detection welding quality.
Advantages of the present invention is as follows：Fundamentally solve this kind of coiled material nothing under complex environment and underground water interference environment
The problem of method is constructed so that it can be widely used in Mining Method engineering, compensate for such material and is difficult application in Mining Method engineering
Defect.Meanwhile, by the welding of mechanization, make overlap joint effect more secure, add the reliability of waterproof.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Numbered in figure：1st, sealant tape, 2, Macromolecular self-adhesive membrane waterproof roll, 3, the double weld seams of overlap edge, 4, double weld seams
The reserved cavity in middle part.
Embodiment
The concrete structure of the present invention is shown in Figure 1.Macromolecular self-adhesive membrane waterproof roll welded lap structure, including：
Reserved cavity (4) and covering bonding between two width coiled materials (2), double weld seams (3) of overlap edge, double weld seams in overlap edge
Sealant tape (1) above overlapping part；The coiled material at the scrap (bridge) position is the structure for removing adhesive layer.
Macromolecular self-adhesive membrane waterproof roll welded lap construction method, comprises the following steps：
Step one：Two width Macromolecular self-adhesive membrane waterproof rolls (2) are in place；
Step 2：The self-adhesive glue layer of coiled material lapping edge position is removed by special equipment, exposes basic unit's sheet material；
Step 3：The double weld seams (3) of overlap edge that two width coiled materials are removed into glue-line by welding machine are overlapped；
Step 4：Welded seal quality is detected by cavity (4) reserved in the middle part of double weld seams；
Step 5：Overlap edge is covered by sealant tape (1), it is respectively provided with self-adhesive film coiled material with both sides coiled material
Characteristic.
The specific implementation step of above-mentioned bridging arrangement and construction method is as follows：
(1) two width coiled materials examination to be overlapped is spliced and positioned.
(2) the reaction glue of two width coiled material lapping edge positions is removed by removing glue device, the overlap edge after taking-up should be clean, puts down
Whole, hand can only feel viscosity slightly after touch.
(3) by overlapping part split, it is ensured that lap width, which is met, to be required, welding machine is in place, is then walked certainly by welding machine
Two width coiled materials are welded afterwards, detection cavity is reserved between double weld seams.
(4) by injecting air in reserved cavity, pressure of satisfying a period of time detection welding quality.
(5) last completely to cover sealant tape in overlapping part, overlap edge construction is finished.
Above-mentioned overlap edge glue-line is removed by special doctor kiss coater, is the basis that follow-up welding quality ensures.Above-mentioned overlap edge
Automatic weld is carried out using welding equipment, the closed of weld seam and reduction ratio of defects is ensure that.Above-mentioned pair of weld seam is reserved to be filled
Gas cavity can carry out seal detection, it is ensured that the globality of overlap edge.Gross area of the above-mentioned Special seal adhesive tape to overlapping part
Covering, it is ensured that overlapping part has the good leakage-proof performance combined with rear pouring concrete together with big face waterproof layer.Cover sealing
Adhesive tape, overlap edge construction is finished.
