Background technology
When embedded tracks system is used in the occasion in bridge or tunnel, needs to do water-proofing treatment, also need to examine in Special zone
Consider special damping requirements.At present, bridge floor and road surface waterproof layer mainly adopt rigidity water-proofing material and flexible waterproof material.Rigidity is anti-
Mainly based on crystal type, the mechanism of action depends not only upon its face coat to water, more importantly can penetrate inside concrete shape
Become crystalline solid, close the passage of water, if but meet concrete cracking, waterproof effect can not be played；Flexible water is mainly coiled material
Type and coating type, coiled material is used for pave-load layer bottom, and coating is generally used for bridge floor, no matter but be coiled material or coating, all can only rise
To waterproof action it is impossible to meet the waterproof of embedded tracks system and special damping requirements simultaneously.If waterproof and embedded rail
System special vibration damping in road separately designs, and will increase working procedure, affects speed of application.
Content of the invention
The goal of the invention of the present invention is: for above-mentioned problem, provide a kind of for embedded tracks system
Waterproof shock-absorption composite construction and construction method, are mainly used in the waterproof and two between embedded tracks system supporting layer and adjustment layer
Level vibration damping, when for bridge section, elastic damping layer therein can also play the effect of sliding layer, can effectively reduce the effect of beam rail
Power.
The technical solution used in the present invention is such that
A kind of waterproof shock-absorption composite construction for embedded tracks system, comprises nonwoven layer, height from top to bottom successively
Molecule waterproof layer and elastic damping cushion, are adhesively fixed between layers.
Preferably, described macromolecule waterproof layer is high density polyethylene (HDPE) is certainly stained with glued membrane waterproof roll, chlorinated polyethylene piece
Material or app modified asphalt waterproof coiled material, two-sided all have from sizing.Described macromolecule waterproof layer is connected with each other using overlapping mode,
Lap width is more than or equal to 100mm.
Preferably, described elastic damping cushion is microporous polyurethane expanded material, density is in 500kg/m3-1000kg/
m3, thickness is 10mm-15mm.Its upper and lower bonding plane all no epidermises, are microcellular structure, lower surface scribbles bonding agent.Described elasticity
The bonding agent that vibration damping bed course lower surface applies is polyurethane adhesive, and thickness is 0.5-1mm, and this adhesive is divided into primary coat dough-making powder to apply,
Primary coat can penetrate into concrete, the intensity of Concrete Structure layer, closing cavity, improves adhesive strength；Face applies to remove has good gluing
Connect outside performance moreover it is possible to have the water resistance of brilliance
The construction method of waterproof shock-absorption composite construction comprises the following steps:
The first step, clears up support layer surface；
Second step, brushing adhesive, adhesive mainly adopts polyurethane adhesive, and brushing should uniformly, and thickness is 0.5-
1mm；
3rd step, lays elastic damping cushion, should ensure that between elastic damping cushion 3 and supporting layer 6 no in process of deployment
Bubble, and it is compacted into it is ensured that closely connected with rubber hammer；
4th step, lays macromolecule waterproof layer, and by the way of overlap joint, each lap width cannot be less than macromolecule waterproof layer
100mm；
5th step, nonwoven layer 1 is bonded on macromolecule waterproof layer, can not tighten it is allowed to have during nonwoven layer laying
Certain fold, thus complete the construction of waterproof shock-absorption composite construction layer；
6th step, track plates lifting is put in place, then pours into a mould from close between in-orbit guidance tape and waterproof shock-absorption composite construction layer
Real concrete forms adjustment layer.
In sum, due to employing technique scheme, the invention has the beneficial effects as follows: waterproof can be simultaneously worked as and subtract
The effect shaken, the bonding agent under sizing and elastic damping cushion of macromolecule waterproof layer top and bottom plays dual waterproof action；
This structure construction is convenient, applies in bridge structure, can play the effect of sliding layer by the detrusion of elastic damping cushion,
Reduce beam rail active force.
