Abstract
The utility model discloses a kind of Bridge guardrail waterproof construction, including floorings, guardrail, pave-load layer, asphalt surface course and waterproof layer.Guardrail is vertically set on the upper surface of floorings, and the upper surface of floorings is provided with pave-load layer, and the upper surface of guardrail side is provided with coiled material close to the inner surface and pave-load layer of pave-load layer in guardrail.According to existing construction technical requirement, the concreting of bridge main body causes often to form crack between both new-old concretes earlier than guardrail.By the setting of this waterproof construction, bridge and guardrail inside steel bar corrosion and concrete carbonization caused by the infiltration of rainwater are reduced, the stability and durability of bridge and guard bar structure is improved, strengthens the security of bridge structure.And this Bridge guardrail waterproof construction can coordinate asphalt surface course overhaul construction operation, be easy to construction and late maintaining.
Description
Technical field
The utility model is related to a kind of Waterproof Construction Technique, more particularly to a kind of Bridge guardrail waterproof construction.
Background technology
During the current Bridge Construction of China, the concreting of bridge main body causes both earlier than guardrail
Crack is often formed between new-old concrete.For the ease of draining, bridge floor can typically set 2% horizontal slope, and rainwater is along overland flow
To guardrail, penetrate into the gap between guardrail and floorings, cause internal steel bar corrosion, concrete carbonization etc..If there is vehicle to hit
Upper guardrail, then guardrail be easy to fracture, it is very dangerous.The design of bridge and guardrail waterproof construction is to the stability of bridge, durable
Property and security have great significance.
The content of the invention
Main purpose of the present utility model is to provide a kind of Bridge guardrail waterproof construction, to strengthen the durable of bridge structure
Property and security, extend Bridge guardrail service life.
The purpose of this utility model and solve its technical problem using following technical scheme to realize.According to this practicality
The Bridge guardrail waterproof construction of new proposition, includes floorings, pave-load layer, asphalt surface course, guardrail and waterproof roll；The shield
The upper surface for being arranged on floorings of column vertically, the pave-load layer is cast in the upper surface of floorings, in guardrail close to pave-load layer
Inner surface and pave-load layer be pasted with one section of waterproof roll close to the upper surface of guardrail side.By setting this section of waterproof to roll up
Material, can avoid or reduce the water flowed down from guardrail and penetrate into the gap between guardrail and pave-load layer, while adding bridge floor rain
Water penetrates into the path length in gap between guardrail and floorings.
Further, height of the described waterproof roll on the inside of guardrail should be greater than 50 ㎜.
Further, the waterproof layer uses EPDM waterproof rolls, and the pave-load layer uses water-proof concrete.
Further, foregoing Bridge guardrail waterproof construction, described waterproof roll is needed first before paving in base
Layer coating polyurethane primer.
Further, foregoing Bridge guardrail waterproof construction, the mixing ratio of polyurethane primer is pressed for polyurethane material
First:Second=1:3 (weight ratios), construction can be coated by stirring.
The construction technology of the Bridge guardrail waterproof construction, including following operating procedure,
（1）Guardrail is set on floorings；
（2）Pave-load layer is poured in floorings upper surface；
（3）After pave-load layer concrete strength reaches the 80% of design strength, by design attitude, in guardrail close to pave-load layer
Inside bottom and pave-load layer close to guardrail side upper surface be coated with polyurethane primer；
（4）On primer waterproof roll is pasted by design attitude.
By above-mentioned technical proposal, the utility model Bridge guardrail waterproof construction at least has advantages below：It is anti-by this
The setting of water-bound, reduces the gap that rainwater is penetrated between guardrail and floorings, it is to avoid or the reinforcing bar reduced through the gap becomes rusty
Erosion, concrete carbonization, improve the stability and durability of bridge and guard bar structure, strengthen the security of bridge structure.
The utility model Bridge guardrail waterproof construction, can coordinate asphalt surface course overhauls construction operation, is easy to construction with after
Phase conserves, with good application value and economic benefit.
Described above is only the general introduction of technical solutions of the utility model, in order to better understand skill of the present utility model
Art means, and can be practiced according to the content of specification, described in detail with preferred embodiment of the present utility model as after.
Brief description of the drawings
Fig. 1 show the utility model Bridge guardrail waterproof construction schematic diagram；
Connotation is marked in figure：1- guardrails, 2- floorings, 3- pave-load layers, 4- waterproof layers, 5- asphalt surface courses.
Embodiment
Further to illustrate that the utility model is to reach technological means and effect that predetermined purpose is taken, to this practicality
The Bridge guardrail waterproof construction of new proposition and its embodiment, feature and its effect of construction technology, are described in detail such as
Afterwards.
Embodiment 1
The Bridge guardrail waterproof construction of the present embodiment as shown in Figure 1, includes guardrail 1, floorings 2, pave-load layer 3, anti-
Water coiled material 4 and asphalt surface course 5.The vertical upper surface for being arranged on floorings 2 of guardrail 1, pave-load layer 3 is arranged on the upper of floorings 2
Surface, is pasted with waterproof close to the upper surface of the side of guardrail 1 close to the inner surface and pave-load layer 2 of pave-load layer 2 in guardrail 1 and rolls up
Material.
During construction according to the following steps：
（1）Guardrail 1 is set on floorings 2；
（2）Pave-load layer 3 is poured in the upper surface of floorings 2；
（3）After the concrete strength of pave-load layer 3 reaches the 80% of design strength, by design attitude, in guardrail 1 close to mating formation
The inside bottom and pave-load layer 3 of layer 3 are coated with polyurethane primer close to the side upper surface of guardrail 1；
（4）After the polyurethane primer of basic unit is dry, paving EPDM waterproof rolls have often spread a coiled material, should be immediately with dry
Net round brush laterally firmly rolling one time since one end of coiled material, so as to which air is discharged.EPDM waterproof rolls are in guardrail 1 one
The height of side is 50 ㎜.
Embodiment 2
The difference of the present embodiment and embodiment 1 is to use water-proof concrete when the pave-load layer 3 of bridge floor is poured, can be more
Plus effectively reduce rainwater from pave-load layer 3 to the infiltration of floorings 2, protect bridge main body structure.
