Description
Technical field
The present invention relates to a kind of construction technologies for preventing coiled material channeling water.
Background technique
Waterproof roll be suitable for industry and the roofings of civil buildings and underground waterproof engineering, roofing protection works, tunnel,
The waterproof of the buildings such as iron and road, bridge；Material for waterproof is mainly coating and various sheet materials or coiled material,
With the appearance of asphalt water-proof coiled material or the macromolecular sheet material of fabric layer, because of its industrialization production, construct convenient easily universal,
It applies in construction and increasingly has been favored by people, especially building top layer terrace, subway terrace and dykes and dams culverts and water gates top
Modified bituminous pitch coiled material is adhered directly onto concrete surface, achievees the purpose that waterproof by the construction in face.
The method of waterproof roll hot melt application at present generallys use adjacent two panels coiled material and overlaps above and below edge, generally deposits
In the overlap edge of 10cm or so, baking is then heated at overlap edge, after roastingization overlap edge adjacent waterproof roll is connected to
Together, it but heating overlap edge and has alice often, playing the case where side, and worker operation inevitably has careless mistake, causes current
As long as waterproof roll leak is all the leak at overlap edge；In addition, this processing method makes waterproof roll form an entirety
(as long as having water below, water can alter always along waterproof roll, can be altered from one side to another side, not obstruct/block), meeting
There is waterproof roll large area channeling water, causes damages to building.
Authorization Notice No. is a kind of patent of 103540147 B of CN: resistance to exfoliated elastomer modified asphalt waterproof of high intensity
Coiled material and production technology calculate, further includes: asphalt by weight including the tire base based on enhanced long polyester tire
60~70 parts, 3~6 parts of TiO_2 nanoparticles, 6~9 parts of Styrene-Butadiene-Styrene Block Copolymer (SBS), C9 petroleum
1~5 part of resin, 2~5 parts of stabilizer, 2~6 parts of AMR antistripping agent and 15~20 parts of talcum powder.The present invention is with higher anti-
Water effect；Its waterproof roll prepared reaches 2.1N/mm through hot melt application, overlapping the slot peel strength.It is still taken using universal
The drawbacks of mode of edge fit hot melt adhesion, this engineering method is, significantly by the waterproof roll of high-temperature baking its waterproof performance
Decline leads to easily leak and earlier the case where destroying, can not solving leak at overlap edge at side seam, can not also prevent waterproof roll
Channeling water phenomenon below material layer.Application publication number is a kind of patent of CN 103774797A: asphalt water-proof coiled material construction technology,
Its construction procedure are as follows: the first step clears up base, and second step is completely brushed viscous with the bituminous neoprene of gasoline cutback together in base
Tie agent；Third step does extra play at turning position, with modified bituminous pitch coiled material hot melt application；4th step, modified asphalt waterproof is rolled up
Material is cut into corresponding size, spools spare, is evenly heated base and coiled material intersection with flame gun, heating in reciprocating mode is rigid in pitch
Just when fusing, coiled material is rolled forward to paving, is affixed in base, overlapping part is cemented by full bonding hot melt；5th step, will with spray gun
It is heated at coiled material lapping seam, is firmly bonded the two, squeezing out pitch with edge is qualification, and it is tight with sealing compound pointing that head is received in end
It is close；6th step, protective layer construction, process of deployment of the present invention is simple, and the effect of laying is good, and each layer is smooth seamless.Its there is also
Overlap edge, can not also prevent the channeling water phenomenon below waterproof roll layer at the case where can not solving leak at overlap edge.
Summary of the invention
It is an object of the invention to overcome defect existing in the prior art, a kind of construction work for preventing coiled material channeling water is provided
Skill, which obviate the defect of coiled material lapping side leak, the water under waterproof roll layer is blocked at binder, can prevent waterproof roll
Material large area channeling water, additionally it is possible to find leak source in time, the position of leakage is accurately positioned.
In order to realize the above technical effect, the technical solution of the present invention is as follows: a kind of construction technology for preventing coiled material channeling water, including
Following steps:
Step 1, base treatment: clearing up base before waterproof roll paving, and base's moisture content after cleaning is not more than 8%；
Step 2 carries out the paving of waterproof roll using cold bonding construction method or hot melt application method；
Wherein, spacing is reserved in step 2 between the adjacent waterproof roll of paving, coats water-resistant type waterproof at reserved spacing
Coiled material edge sealing binder.The construction method for changing previous traditional waterproof roll, by former adjacent two panels coiled material in edge
The mode of hot-melt adhesive paste is changed to reserve spacing between adjacent waterproof roll after overlap joint up and down, then viscous using water-resistant type waterproof roll edge sealing
The mode of reserved spacing is filled and led up in knot agent, high with the adhesive strength of base, coiled material due to the resistance to bubble of binder, such waterproof roll
Water under layer is blocked at binder, can prevent waterproof roll large area channeling water, additionally it is possible to be found leak source in time, is accurately positioned
The position of leakage；And this construction technology can be used for cold bonding construction method.
Further preferred technical solution is that it is 2cm~15cm that spacing is reserved between the adjacent waterproof roll of paving.
Preferred technical solution is if step 2 carries out the paving of waterproof roll using cold bonding construction method, including to walk as follows
It is rapid:
A. one layer of adhesive bitument primer is first brushed in base；
B. after waterproof roll being put well by predetermined position, start paving, should all vertically and horizontally reserve 2cm~15cm it is reserved between
Away from flat with the painting of water-resistant type waterproof roll edge sealing binder；
If c, needing the double-deck waterproof, the longitudinal joint of the second layer single waterproof roll that must at least be staggered with the longitudinal joint of first layer is wide
The one third of degree, 1 meter of shift of butts or more.
Further preferred technical solution is, if step 2 carries out the paving of waterproof roll using hot melt application method, including
Following steps:
A. one layer of adhesive bitument primer is first brushed in base；
B, waterproof roll is put well by predetermined position, base and coiled material bottom surface is heated with liquefied gas or gas and oil blowtorch, to surface
After asphalt melting a thin layer, the rolls forward coiled material in baking, and use roller compaction；
C, it is vertically and horizontally 2cm~15cm that waterproof roll, which reserves spacing, is filled and led up with water-resistant type waterproof roll edge sealing binder；
If d, needing the double-deck waterproof, the longitudinal joint of the second layer single waterproof roll that must at least be staggered with the longitudinal joint of first layer is wide
The one third of degree, 1 meter of shift of butts or more.In this way using adjacent waterproof roll reserve spacing and edge it is non-overlapping by the way of,
The dosage of coiled material can be saved, 13%~14% waterproof roll can be saved, to a certain extent save the cost, it is effectively save
With the usage amount of coiled material on homalographic；Binder between adjacent web plays the role of barrier/blocking water, and coiled material can be prevented big
Area channeling water reduces large area channeling water and loses caused by building.Pay attention to adjusting flame size in step b, melts coiled material table
Face pitch cannot trickle too much, can not bake；Wherein, water-resistant type waterproof roll edge sealing binder specifically uses Jiangsu nation
