Abstract
The present invention relates to a waterproof structure for bridge surfaces and a construction method thereof. The structure comprises a bridge surface 2 and a waterproof structure 1 from top to bottom, wherein the waterproof structure 1 comprises a waterproof layer 3, a tabular object layer 4 and an asphalt mixture spreading layer 5. The present invention has the construction steps: firstly, coating a layer of priming paint on the bridge surface, wherein the priming paint can be epoxy resin or polyurethane resin; secondly, coating the waterproof layer on the priming paint, wherein the waterproof layer can be polyurethane resin or allyl resin or polyurea aldehyde resin or chloroprene resin, etc.; thirdly, paving the tabular object layer after the waterproof layer is painted, wherein the tabular object layer can be plate made of thermoplastic resin, or fabric, braid or non-woven cloth made of thermoplastic resin fiber or blend fiber which contains much thermoplastic resin fiber; fourthly, spreading the asphalt mixture layer after the tabular object layer is paved, wherein the mixture of ordinary paving asphalt and skeletal materials is heated to the temperature of 150 to 180 DEG C to be spread on the tabular object layer, so that the construction for the waterproof structure of the whole bridge surface is finished.
Description
Technical field
The present invention relates to a kind of bridge floor with waterproof construction and job practices thereof, especially about overlay a kind of waterproof construction and the job practices thereof of waterproofing course on the surface of steel bridge.
Background technology
The surface of steel bridge is because of the influence of weather conditions such as wind-engaging, frost, snow, rain, and its pavement performance is variation gradually, and the life-span shortens greatly.In above-mentioned climate change factor, rainwater has the greatest impact to bridge floor, often being in the bridge floor of moisture state compares with the bridge floor that often is in dry state, will shorten 1/1000 fatigue life, in numerous factors of application life that influences bridge floor and pavement performance, the influence of water can not be ignored, so bridge deck water-proof is the effective means that keeps the bridge floor durability.
How to realize effective waterproof of bridge floor, be that people are designing bridge and building one of problem of being concerned about the most in the bridge process, people have carried out many deep researchs to this all the time, adopt various method that bridge floor is designed, constructs, transforms, make every effort to reach the optimum efficiency of bridge deck water-proof.Bridge deck water-proof scheme at present commonly used has following several: a kind of scheme is to smear waterproofing materials such as polyurethane as waterproofing course on bridge floor, on waterproofing course, overlay asphalt mixture again, though this method waterproof effect is better, but polyurethane water-proof layer and the asphalt mixture smeared are bonding bad, and bridge floor breach, crack and interlayer occur and separates after a period of time; A kind of scheme is to smear the purpose that asphalt emulsion reaches waterproof on waterproofing course, and the shortcoming of this scheme also is that asphalt emulsion follows the cohesive of waterproofing course bad, and the time dry, that curing needs is long.In order to solve waterproofing course and the bonding bad problem of asphalt mixture in the above-mentioned bridge deck water-proof scheme, people strengthen its cohesive with aqueous binders such as epoxy resin, but the binder sclerosis needs the long time, if binder is fully sclerosis not, the problem of viscose glue mixture on the doughnut can appear.
Japanese kokai publication hei becomes patent 9-21113 also to disclose a kind of bridge deck water-proof structure, and it is earlier the thermoplastic resin shot-like particle to be dispersed on the waterproofing course, overlays hot-mix asphalt more in the above.Though this patented technology waterproof effect is pretty good, but exist the thermoplastic resin shot-like particle to scatter uneven problem, if and when construction wind bigger, can dispel the synthetic resin shot-like particle that scatters, some areas will appear like this because of there not being the synthetic resin shot-like particle bonding bad, before scattering the thermoplastic resin shot-like particle, need special equipment such as thawing jar that it is carried out heating and melting in addition, it is a lot of that construction cost is increased.
Summary of the invention
Purpose of the present invention is exactly the problem that exists in the existing bridge deck water-proof scheme in order to solve, and realizes that waterproofing course and asphalt mixture are well bonding, and for bridge construction provides cheaply, the bridge floor of good work is with waterproof construction and job practices.Structure of the present invention is followed successively by bridge floor 2 from top to bottom shown in Figure of description 1, waterproof construction 1, waterproof construction 1 comprise three layers again: waterproofing course 3, plate object layer 4 and bituminous mixture laying layer 5.
The concrete construction sequence of the present invention is: before smearing waterproofing course, on bridge floor 2, be coated with earlier one deck priming paint, this priming paint can use epoxy resin, also can be with polyurethane etc., when being coated with priming, scatter aggregates such as light weight sand simultaneously on priming paint, the purpose of doing like this is to prevent departing from of waterproofing course and bridge floor.Be coated with on the bridge floor after the priming paint, be coated with waterproofing course 3 again, the used resin of waterproofing course of the present invention can be selected polyurethane resin, allyl resin for use, poly(urea formaldehyde) resin or neoprene resin etc.The brushing of waterproofing course 3 can adopt spraying to be coated with, to brush, and cylinder is coated with etc.After waterproofing course has been coated with, just plate object layer 4 can have been disposed in the above, the plate object layer 4 that is disposed can be the plate that 60～150 ℃ thermoplastic resin is made with softening point, the also fabric that can make of the blend fibre that occupying the majority by the thermoplastic resin fibre or by the thermoplastic resin fibre, braid or the non-cloth that spins are done plate object, and the weavy grain size is 5g/m
2～500g/m
2The fabric that the blend fibre of selecting for use thermoplastic resin or thermoplastic resin to occupy the majority is made, the advantage that yarn fabric or nonwoven fabric are done plate object is when we overlay hot asphalt mixture on plate object, thermoplastic resin can see through and weave cotton cloth, the slit of nonwoven fabric makes the good bonding of waterproofing course and asphalt mixture.Behind the intact plate object layer 4 in waterproofing course 3 upper berths, just only remaining last procedure overlays hot asphalt mixture paving layer 5, pave on plate object after the pitch of the usefulness of paving the way usually and aggregate mixture be heated to 150～180 ℃, whole like this bridge deck water-proof system just construction has finished.
A kind of bridge floor of the present invention is not scatter the thermoplastic resin shot-like particle as waterproofing course to have the uneven worry of distribution like that with the advantage of waterproof construction and job practices thereof, and the good bonding of the waterproofing course of whole construction scope and asphalt mixture, the job site does not need to melt jar and waits equipment.The present invention has overcome drying, the curing of using asphalt emulsion to exist needs long problem of time, and also not resembling has the worry that is stained with adhesive on the tire when using aqueous binder.
Description of drawings
Fig. 1 is the structural representation of a kind of bridge floor of the present invention with waterproof construction and job practices thereof;
Among the figure, be followed successively by from top to bottom:
Bridge floor 2, waterproof construction 1, waterproof construction 1 comprise three layers again: waterproofing course 3, plate object layer 4 and bituminous mixture laying layer 5.
