Topic, so that beams of concrete face is with good waterproof effect and has excellent bond effect.
The purpose of the present invention is achieved through the following technical solutions:
A kind of beams of concrete face with waterproof roll, beams of concrete face is from top to bottom followed successively by protective layer, waterproof roll
Layer and concrete base layer, the one side of the waterproof roll layer passes through with the protective layer to be bonded as one, the waterproof roll
The another side of layer is with the concrete base layer using bonding agent by being bonded as one；
The waterproof roll layer from top to bottom sets gradually as polyester filament geotextiles and kiss-coating canvas, the polyester filament
Geotextiles with the kiss-coating canvas while be bonded as one, the another side of the kiss-coating canvas and the coagulation soil matrix
Layer is bonded as one, and another side and the protective layer of the polyester filament geotextiles are bonded as one.
Further, the bonding agent is two-component epoxy polyurethane class bonding agent.
Further, epoxy resin adhesive and polyurethane adhesive in the two-component epoxy polyurethane class bonding agent
Mass ratio is 1:(1.8-2.2).
Further, the mass area ratio of the polyester filament geotextiles is 195-205g/m2, with a thickness of (1.3-
1.5)±0.05mm；The kiss-coating canvas is the polyester-cotton blend union duck of frictional both sides.
Further, the content of polyester fiber and cotton fiber ratio is (70-90): (30-10) in the polyester-cotton blend union duck,
The specification of the polyester-cotton blend union duck is 3 × 3,4 × 4,4 × 8,5 × 8；The polyester-cotton blend union duck with a thickness of (0.35-
1.0) ± 0.05mm, width are 100 ± 1cm, and length is 100 ± 5m.
Further, the protective layer be pitch protective layer, the pitch protective layer with a thickness of 40-60mm.
Further, the pitch protective layer is grouped as by the group of following parts by weight: 100 parts of matrix pitch, butadiene-styrene rubber
15-25 parts, 40-50 parts of Petropols, 3-5 parts of plasticizer, 2-3 parts of antioxidant.
The construction method in the above-mentioned beams of concrete face with waterproof roll, includes the following steps:
Step 1: cleaning sundries and laitance, remove basal plane floating dust with high pressure blower, guarantee basal plane cleaning and drying, then
Concrete is transported to road scene afterwards after mixing, carries out pavement spread using spreading machine, use steel roller height
After frequency low amplitude vibration rolls 2-3 times, reuses pneumatic-tired rollers and roll 1-2 times to get concrete base layer；
Step 2: two kinds of components of bonding agent are stirred in advance, it is uniform after the completion of mixing to brush in coagulation soil matrix
On layer, when brushing, must not splash because of stream or other reasons due tos pollutes beam body, and the waterproof roll to complete is fitted in 40min
On concrete base layer, exhaust compacting, edge sealing solidification stands at least 30min and bonding agent II is fully cured to get waterproof roll
Layer；
Step 3: matrix pitch, butadiene-styrene rubber, Petropols, plasticizer and antioxidant are added according to weight

Further, the revolving speed that bonding agent is stirred in the step 2 is 100-500r/min, and the bonding agent exists
The use of 30min domestic demand finishes after the completion of mixing；Brushed in the step 2 with a thickness of 1.7-2.3mm；It is sealed in the step 2
While being cured as being at least the cured layer of 1.5mm using bonding agent brushing a layer thickness；Edge sealing solidifies in the step 2 are as follows: waterproof
Coiled material is laid with to pushing off the slag, interior abutment wall, end edge wall inboard root, and waterproof roll should first be laid with a pair of pushing off the slag side, in overlap joint
Make the pair under, it is another secondary upper, it forms coiled material and is had a common boundary along bridge floor longitudinal center, lap width is not less than 80mm, when two
It, can be supreme to the supreme corner chamfer of slag blocking wall inboard root, interior abutment wall and end edge wall inboard root after secondary coiled material is pasted
The facade brushing bonding agent of mouth, while edge sealing is carried out to the periphery of waterproof roll, edge sealing width cannot be less than 80mm, adjacent web
Overlap joint is received and is brushed along coiled material lapping center line to both sides at head with epoxy polyurethane bonding agent, and two hem width degrees are no less than 80mm, lean on
Be all made of at the waterproof roll edge and beam body of nearly shelves quarrel wall and at sluicing nozzle and protective layer epoxy polyurethane bonding agent into
The processing of row edge sealing, edge sealing width are no less than 80mm, brush with a thickness of 1.0-1.5mm；The exhaust pressure is actually: rubber composite fibre
The paving of waterproof roll answer it is smooth, it is no it is damaged, must not be tilted without hollowing, lap-joint and periphery, can be arranged with pin hole if any a drum is played
Gas method, with gasket coating sealing of hole: can be subsidized with coating to position is tilted at alice.
The beneficial effects of the present invention are:
1. two-component epoxy polyurethane class bonding agent is used to paste the bonding coating of rubber composite fibre waterproof roll, forgo
It the drawbacks of base treatment agent environmental pollution of traditional asphalt base and can be greatly improved, have anti-in terms of comprehensive performance
The features such as aqueous energy is high, moderate, good extending performance and rotproofness and base adhesive power are strong；
2. polyester-cotton blend union duck is in order to increase the diameter of base fabric, latitudinal strength, using a small amount of using a large amount of polyester fiber
Cotton fiber be in order to good processing performance and increase cloth and rubber adhesive force, to increase the globality of adhesive plaster；
3. waterproof roll layer plays the effect of isolation, continuous and efficiency buffering, the adhesive effect of waterproof roll layer is good, mentions
The effect of height prevention and treatment reflection crack, reduces the loss of composite material in the construction process.
