Fruit the ponding inside bridge is not discharged in time, and the ponding of bridge floor will penetrate into bottom in bridge downwards, to influence bridge
Service life, and make bridge can not be in dry, firm and stable state, to be easy to appear bridge deformation or collapse existing
As.
Utility model content
The purpose of the utility model is to provide a kind of dewatering type highway bridge structures, and which solve bridges due to internal ponding
The problem of leading to bridge stability poor problem.
The above-mentioned technical purpose of the utility model has the technical scheme that
A kind of dewatering type highway bridge structure, including bridge, the bridge include that the pitch from top to bottom set gradually mixes
Solidifying soil surface layer, pervious concrete layer, water barrier, waterproof layer and concrete base layer, the pervious concrete layer and the waterproof layer
Between be provided with drainpipe, the draining bottom of the tube is fixed on the waterproof layer top, passed through at the top of the drainpipe it is described every
Water layer and it is located at the pervious concrete layer bottom, water inlet is offered at the top of the drainpipe, the water inlet is located at described
In pervious concrete layer, the water barrier and the draining tube outer surface are tightly connected；
The drainpipe both ends extend to outside the bridge and are connected with water tank, the drainpipe and the water tank
Connection setting.
Using the above structure, rainwater is permeated downwards by asphalt concrete pavement and pervious concrete layer, due to permeable mixed
Water barrier is set below solidifying soil layer, therefore rainwater will be intercepted in pervious concrete layer, thus through water inlet, the row of being flowed into
It in water pipe, and is entered in water tank by drainpipe, to achieve the purpose that draining.The water that bridge floor can be permeated is timely
It discharges, prevents bridge upper surface and internal ponding, improve the stability of bridge, reduce bridge settlement, deform and collapse
Phenomenon.
It advanced optimizes are as follows: water inlet is provided with sponge sheet at the top of the drainpipe, and the sponge sheet is located at described
In water coagulation soil layer and it is coated on the drainpipe outer surface of cupular part.
Using the above structure, draining is entered by water inlet to prevent impurity such as sand, rubbles in pervious concrete layer
Guan Zhong reduces drainpipe, water tank clogging.
It advanced optimizes are as follows: the water barrier is arc shape, and height and position is gradually decreased from middle part to two sides.
Using the above structure, so that rainwater is permeated along water barrier into the exterior earth of bridge two sides, while can also subtract
Rainwater on the outside of few bridge is permeated to bridge internal direction, convenient for discharge ponding in time, extends the service life of bridge.
It advanced optimizes are as follows: the water barrier is made of two cloth, one film seepage by geo-textile material.
Using the above structure, rainwater can be intercepted in pervious concrete layer, prevent rainwater from permeating downwards by good water-proof effect
Into waterproof layer and concrete base layer.
It advanced optimizes are as follows: the waterproof layer includes polyurethane water-proof paint layer and bitumen slurries layer, and the polyurethane is anti-
Water paint layer is located above the bitumen slurries layer and pastes setting with it.
Using the above structure, it prevents rainwater from penetrating into bottom in bridge downwards, plays the role of exclusion of water, so that in bridge
Portion is in dry environment, improves the stability of bridge internal structure.
It advanced optimizes are as follows: the drainpipe is provided with multiple, and multiple drainpipes are along described bridge width direction etc.
It spacing arrangement and is connected to respectively with the water tank.
Using the above structure, rainwater can be discharged in time, drainage effect is preferable.
In conclusion the utility model has the following beneficial effects: rainwater passes through asphalt concrete pavement and permeable coagulation
Soil layer permeates downwards, and since water barrier being arranged below pervious concrete layer, rainwater will be intercepted in pervious concrete layer,
It to penetrate sponge sheet and water inlet, is flowed into drainpipe, and is entered in water tank by drainpipe, to reach draining
Purpose.The water that bridge permeates can be discharged in time, prevent ponding inside bridge, improve the stability of bridge, dropped
Low bridge settlement, deformation and collapse phenomenon extend the service life of bridge.
