Description
Technical field
The utility model relates to Highway bridge technique field, specifically a kind of highway bridge waterproof layer device.
Background technology
The highway bridge of prior art, main is all the floorings of armored concrete, and this reinforced concrete bridge deck plate is put down
When need to be subjected to the influence of a variety of external force such as vibrations, impact, stretching and the shearing of vehicle heavy load, and due to temperature, weather
After expansion, contraction caused by change, often produce trickle crack and cause water permeating of bridge floor or leak, and then cause inside
Steel bar corrosion, influence the bulk life time of bridge.Especially in the joint portion of cast-in-place concrete, although applying in design and specifically
Many safeguard procedures are taken during work, but always there are the link of weakness, the generation in crack are caused, if carrying out not in time
Water-proofing treatment, the whole service life of bridge certainly will be reduced, reduce the time limit used.
Presently the most conventional bridge deck water-proof structure is that water-repellent paint or stickup are sprayed on the concrete base layer of bridge
Modified asphalt waterproof coiled material, heated bitumen concrete is then laid on modified asphalt waterproof coiled material again.And the situation of reality is often
That can not be fused into one in the constructing operation of asphalt at the scene with waterproof coating or waterproof roll, and it is frequent because
Cohesive force between asphalt and waterproof coating or waterproof roll is insufficient and produces and slides stripping, the result ultimately resulted in
It is that bituminous paving slides because the cohesive force between asphalt and waterproof roll is insufficient, or even being peeling property is broken
It is bad so that the waterproof layer for working laboriously to set can not play a part of waterproof.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of highway bridge waterproof layer
Device, it is simple in construction, it is reasonable in design, the infringement of rainwater and sunlight to highway bridge can be effectively prevented, improves highway bridge
Service life.
To achieve the above object, the technical solution adopted in the utility model is：A kind of highway bridge waterproof layer device, comprising
Body substrate, modified asphalt waterproof coiled material, the non-woven geotextile of impregnating pitch, plastic, rubber layer and sun-proof film layer；Described
The upper surface of body substrate is provided with modified asphalt waterproof coiled material, and the upper surface of the modified asphalt waterproof coiled material is provided with dipping
The non-woven geotextile of pitch, the upper surface of the non-woven geotextile of described impregnating pitch are provided with plastic, rubber layer, the plastics
The upper surface of rubber layer is provided with sun-proof film layer.
Further, the thickness of the sun-proof film layer is 20~25mm.
Further, the non-woven geotextile of the impregnating pitch is stratum reticulare shape.
The beneficial effects of the utility model are：It is simple in construction, it is reasonable in design, it can effectively prevent rainwater and sunlight to highway
The infringement of bridge, improve the service life of highway bridge.
