As shown in fig. 1, the present invention provides a drainage structure for an expansion joint, comprising:
the first hydrophilic flow guide part 1 is attached to the outer side of a boundary surface between an asphalt structural layer 2 and a concrete pavement layer 3 on one side of the slope height of the bridge (the bridge has a certain gradient, an expansion joint divides a section of the asphalt pavement layer into two sections of high and low according to the height of a longitudinal slope, and an expansion joint water drainage structure is only arranged at the boundary surface between the asphalt structural layer 2 and the concrete pavement layer 3 on one side of the slope height and is arranged along the boundary surface;
a plurality of second hydrophilic flow guiding pieces 4 are arranged at intervals along the length direction of the first hydrophilic flow guiding piece 1, one end of each second hydrophilic flow guiding piece 4 is fixed at the position of a joint between the asphalt structure layer 2 and the concrete pavement layer 3 together with the first hydrophilic flow guiding piece 1, the other end of each second hydrophilic flow guiding piece 4 penetrates through a gap at the beam end and then extends into the center joint and extends downwards to the position below the beam, and the second hydrophilic flow guiding pieces 4 extend downwards to the position below the beam, so that interlayer water can quickly downwards move under the action of gravity and the siphon action of the second hydrophilic flow guiding pieces 4 and finally is discharged to the position below the beam;
a plurality of waterproof pieces 5, it equals with the quantity of the hydrophilic water conservancy diversion spare 4 of second, and the one-to-one, each waterproof piece 5 all sets up on the outer peripheral face of the hydrophilic water conservancy diversion spare 4 of second rather than corresponding, and makes the hydrophilic water conservancy diversion spare 4 of second rather than corresponding extend downwards towards the other end by one end, and waterproof piece 5 cover is or is wrapped up or cover on the hydrophilic water conservancy diversion spare 4 of second promptly. Through set up waterproof part 5 in second hydrophilic water conservancy diversion spare 4 periphery to fix each second hydrophilic water conservancy diversion spare 4 and first hydrophilic water conservancy diversion spare 1 in the seam position department between pitch structural layer 2 and concrete pavement layer 3, can prevent that each second hydrophilic water conservancy diversion spare 4 and first hydrophilic water conservancy diversion spare 1 from producing the displacement when concrete placement.

In another technical scheme, in the expansion joint water draining structure, the higher end of each waterproof part 5 is close to the first hydrophilic diversion part 1, and the lower end of each waterproof part extends out of the expansion joint reserved groove. The PVC pipe is preferably extended out of the expansion joint reserved groove, and the specific length is determined according to the size of the expansion joint reserved groove.
The expansion joint water draining method comprises the following steps:
firstly, arranging a first hydrophilic flow guide member 1 along an interface between an asphalt structure layer 2 and a concrete pavement layer 3 on one side of the bridge slope height, and enabling the first hydrophilic flow guide member 1 to be attached to the outer side of the interface;
step two, set up many hydrophilic water conservancy diversion spares 4 of second along the length direction interval of first hydrophilic water conservancy diversion spare 1, and all fix the seam position department between pitch structural layer 2 and the layer 3 of mating formation of concrete with the one end of every hydrophilic water conservancy diversion spare 4 together with first hydrophilic water conservancy diversion spare 1, the other end passes waterproof 5 and extends downwards to extend under the roof beam after penetrating the centre joint through the beam-ends gap, after the expansion joint construction is accomplished, the interlaminar water between pitch structural layer 2 and the layer 3 of mating formation of concrete arranges to under the roof beam along first hydrophilic water conservancy diversion spare 1 and many hydrophilic water conservancy diversion spares 4 of second.
The technical scheme can also comprise the following technical details so as to better realize the technical effects: the bottom of the first hydrophilic flow guide member between the two second hydrophilic flow guide members is gradually inclined downwards from the middle part to two ends of the first hydrophilic flow guide member (for example, linen can be wound on the first hydrophilic flow guide member, and the winding thickness of the linen is gradually increased from the middle part of the first hydrophilic flow guide member between the two second hydrophilic flow guide members to two ends of the first hydrophilic flow guide member), so that after the first hydrophilic flow guide member is rotten, the bottom of a drainage channel formed between the two second hydrophilic flow guide members is in an inverted V shape, and thus, the water in the channel is favorably flowed into the drainage channel formed after the second hydrophilic flow guide members are rotten.
After a drainage channel is formed at the position of an original hemp rope, a new hemp rope is fixed in the drainage channel formed by the original second hydrophilic diversion piece through an inverted V-shaped elastic sheet so as to quickly discharge water in the drainage channel formed after the first hydrophilic diversion piece is rotten, wherein, two sheet bodies of the inverted V-shaped elastic sheet are respectively provided with a notch along the length direction thereof so as to respectively form a U shape, one end of the hemp rope downwards passes through one notch, the other end downwards passes through the other notch so as to be hung on the inverted V-shaped elastic sheet, a rod body is arranged between the two ends of the hemp rope and is propped and fixed at the tip part of the elastic sheet, then the tip part of the elastic sheet is propped into a PVC pipe through the rod body, at the moment, the two sheet bodies are respectively inwards extruded, and when the elastic sheet is propped to the intersection of the drainage channel formed by the first hydrophilic diversion piece and the second hydrophilic diversion piece, the drainage channel that the hydrophilic water conservancy diversion of second formed no longer has the restriction to the shell fragment, the shell fragment is opened, the back is opened to the shell fragment, the drainage channel that can't form through the hydrophilic water conservancy diversion of second for the rope made of hemp fixes in the drainage channel that the hydrophilic water conservancy diversion of second formed, treat the rope made of hemp and rot the back, can outwards stimulate the body of rod, make two lamellar bodies upwards rotate to the drainage channel that can form through the hydrophilic water conservancy diversion of second, can take out the shell fragment and the body of rod, later change the rope made of hemp again according to above-mentioned method.
The invention discloses a method for draining water for an expansion joint, which comprises the following steps:
when the expansion joint is constructed, 1.5cm diameter hemp ropes are placed in the longitudinal through length of the position between an asphalt structure layer on one side of the longitudinal slope of the bridge and a concrete pavement layer, one transverse hemp rope is arranged at intervals of 1.5m, 5cm steel nails are adopted to fix the longitudinal hemp ropes and the transverse hemp ropes at the joint position between the asphalt structure layer and the concrete pavement layer, the steel nails penetrate through the longitudinal hemp ropes and the transverse hemp ropes and are nailed into the joint, the transverse hemp ropes penetrate through a 2cm diameter PVC pipe and stretch into a center joint through a beam end gap and extend downwards to the position under a beam, the diameter of the transverse hemp ropes is 1.5cm, the length of the transverse hemp ropes is 1m (the length can be adjusted according to the width of the expansion joint), and the hemp ropes can be prevented from being displaced when concrete is poured through the fixation of the steel nails and the PVC pipe.
