Abstract
The invention relates to a concrete wall construction joint waterproof treatment method which comprises the steps of (1) cleaning a wall, (2) laying a first layer of waterproof coiled material, (3) laying a second layer of waterproof coiled material, (4) laying a third layer of waterproof coiled material and (5) attaching an outer protective layer. Compared with the prior art, the method has the advantages that a mode of stacking multiple layers of coiled materials is adopted, so that wall construction joints with a waterproof requirement are effectively protected, and an underwater leakage phenomenon caused by failure of waterproof measures is avoided; the waterproof coiled materials are not attached to a basic layer within a range and properly reserve expansion amount, so that the ability of a waterproof layer adapting to basic layer deformation is improved, and the waterproof coiled materials are prevented from being bumpy and cracking; the protective layer is additionally disposed outside the coiled materials, so that construction portions are protected from underground water or erosion of corrosive matter; the method is easy and convenient to operate, and people only need to operate according to conventional construction methods.
Description
Technical field
The present invention relates to the waterproofing work technical field in building operations, relate in particular to a kind of concrete wall Case Study on Construction Joint Water-proofing.
Background technology
In the time of box foundation or basement construction, the concrete of base plate and side fascia separately waters and smashes, and waters a constuction joint of section existence of smashing R.C. wall board for twice, in the time that the position of this seam is in below phreatic line, just easily produce infiltration, therefore must carry out waterproofing work to constuction joint place.The method of processing is a lot, and commonplace method is that steel plate for sealing water or waterstop are set in waterproof concrete body of wall at present, simultaneously one deck waterproof roll of side wall paving outside or brushing one deck penetrant crystalline waterproofing materials.This construction method only arranges waterproof measure one at body of wall upstream face, under the long period of soaking corrosiveness of underground water, or under differential settlement and soil body freeze thawing acting in conjunction due to building, once waterproof roll plays drum cracking or water-repellent paint lost efficacy, will cause seepage phenomenon under anti-water destruct spot, ground water seepage is to engineering inside, can make engineering interior decoration and equipment accelerate corrosion, affect the normal use of building products, and use machinery to get rid of engineering internal leak water, need to expend mass energy and funds.
Summary of the invention
The invention provides a kind of concrete wall Case Study on Construction Joint Water-proofing, adopt the method for waterproof roll multilayer lay-up reserved stroke, strengthen the waterproofing work at wall construction seam place, avoid causing ground water seepage phenomenon because of waterproof failure.

2) paving first floor waterproof roll, in the each 30～60mm wide region in upstream face constuction joint both sides, do not paste, after middle reserved (the not pasting body of wall width+10～30mm) width of first floor waterproof roll, both sides and body of wall cement, and paste width 80～120mm;
3) paving second layer waterproof roll, within the scope of first floor waterproof roll, do not paste, after reserved in the middle of second layer waterproof roll (first floor waterproof roll is pasted width+20～40mm) width, both sides start to paste from the body of wall at first floor waterproof roll edge, paste width 80～120mm with body of wall;
4) the 3rd layer of waterproof roll of paving, within the scope of second layer waterproof roll, do not paste, after reserved in the middle of the 3rd layer of waterproof roll (second layer waterproof roll is pasted width+30～50mm) width, both sides start to paste from the body of wall at second layer waterproof roll edge, paste width 80～120mm with body of wall;
5) the 3rd layer of waterproof roll paving complete after; paste topping in its outside; protective layer thickness 40～80mm, topping outer ledge exceeds the 3rd layer of each 80～120mm in waterproof roll edge, and topping can carry out backfill construction or the construction of integral waterproofing layer after having constructed.
Described waterproof roll is the one in SBS rubber modified asphalt coiled material, APP (APAO) modified bituminous pitch coiled material, PVC modification tar asphalt coiled material, rubber powder modified asphalt coiled material or modification drop polyethylene tire (OEE) coiled material.
Described topping is the one in extruded sheet, benzene plate or phenolic board.
The minimum density of described extruded sheet is 22kg/m
3, the minimum density of benzene plate is 18kg/m
3, the minimum density of phenolic board is 22kg/m
3.
Compared with prior art, the invention has the beneficial effects as follows:
1) the present invention adopts the mode of waterproof roll multilayer lay-up, and the wall construction seam position that has waterproof requirement is effectively protected, and avoids because of the waterproof measure ground water seepage phenomenon causing that lost efficacy;
2) waterproof roll and basic unit do not paste within the scope of one, and suitably reserved stroke of waterproof roll, increase the ability that waterproofing course adapts to basic unit's distortion, are conducive to prevent that waterproof roll from playing drum, cracking;
3) waterproof roll adds topping outward, can further protect construction part not to be subject to underground water or have the erosion of corrosiveness material;
4) simple to operation, construction method operation routinely.
