Description
Technical field
The present invention relates to field of bridge construction, and in particular to a kind of Bridge Seismic combined based on two-ash soil and waste tire
Construction method.
Background technology
Bridge on highway is the important feature in " lifeline engineering ", in the high-grade highway construction of Canal in Loess Area, by
In the requirement of linear standard and the limitation of topographic and geologic condition so that the bridge proportion of this area is also increasing.From
From the point of view of built high-grade highway investigation, bridge structure object about averagely 5/kilometer.There are 85 freeway bridges of scholar couple
Vehicle bump investigation statistics show that the bridge with vehicle bump after platform accounts for 99%, therefore, Loess Area for Expressway after Liang Tai
Vehicle bump has certain generality after bridge platform.
High-grade highway " bumping at bridge-head " problem is often happened at the abutment of highway, culvert (channel) and retaining wall and roadbed
Junction, mainly by bridge the back of the body roadbed subsidence or attachment strap depression, break to form step, when vehicle by when generate jump the phenomenon that,
The study found that the harm that " bumping at bridge-head " problem is brought to people's production and living is mainly manifested in the following aspects：
(1) high efficiency operation is restricted
It researchs and analyses and shows：When step height is more than 4cm, speed amount of decrease will have significantly with the increase of step height
Increase.Wherein step often increases 1cm, and running speed will reduce by 2~3km/h.And on high-grade highway, it has along the line multiple
Bridge, therefore " bumping at bridge-head " vehicle can be caused significantly to slow down, it is serious to restrict high-grade highway high efficiency operation.
(2) driver and passenger is made to feel discomfort of jolting
When vehicle cross jump vehicle point when generate jump and impact, make driver and conductor feel to jolt it is uncomfortable, nervous, hold
Fatiguability and carsickness.
(3) increase resource consumption and environmental pollution
According to《Automobile journal》Relevant information shows automobile by jumping vehicle point, and often bounce is slowed down once, and oil consumption will be averagely increased
60ml.In addition, loud noise can be caused, increase exhaust gas discharge capacity by accelerating and slowing down, environment is polluted.
In addition to this, high-grade highway " bumping at bridge-head " can lead to traffic accident (especially vehicle mechanical accident), simultaneously
The vehicle of jump generates additional impact load to bridges and culverts and road surface again, and high-grade highway is made to easy to produce track and transverse crack.
To increase maintenance costs and reduce road occupation quality.
With the fast development of automobile industry, a large amount of waste tire becomes a kind of novel noxious waste pollution source.
According to incompletely statistics, end the end of the year in 2004, the tire waste in the U.S. is up to 3,800,000 tons, 3,300,000 tons European, Japan 1,200,000
Ton, the yield of China's waste tire is more than 1.12 hundred million, by 2010 more than 200,000,000.These waste tires largely heap,
It occupies cultivated land, destroys vegetation, and stacking can cause mosquito for a long time, be easy to spread the disease, be unfavorable for health；If by its time
It receives and recycles, then cost is higher；It is not degradable if being filled as solid waste, it is easy burning and fire occurs；According to
The method of burning is handled, then will produce a large amount of toxic gases.The processing method of China's waste tire mainly has tyre rebuilding, production
On reclaimed rubber and rubber powder.The object of tyre rebuilding is mainly bias tire engineering tire, aviation tire and load-carrying tire, to radial-ply tyre not yet shape
At real renovation ability.According to the Production trend of tire, the meridian rate of world's tire is up to 90%, and developed country is such as
The U.S., France, Britain, Germany, Italy, Japan etc., tire meridian rate is up to 100%, therefore, the Gao Zi of China's tire
Noon rate has been inevitable.So the high meridian trend of tire just becomes China's tire with radial-ply tyre reconditioning technology backwardness
Renovate the principal contradiction of industry.However, even if tyre retreading technique increases, renovation tire still can become after a certain time
Pending waste and old tire, so, tyre rebuilding processing method is the meter rather than fundamental policy of equity.
For the waste tire that cannot be renovated, domestic common practice be with production reclaimed rubber and rubber powder.However, being given birth to
Produce the restriction of equipment, the factors such as technical merit, the less varieties of reclaimed rubber and rubber powder, outlet less, deep processed product it is few.In addition, again
Volume of the raw rubber in tire is generally 5% one 10%, and the volume in industrial product is generally 10% one 20%, therefore, rubber
Glue industry is limited to the demand of reclaimed rubber.Rubber powder equally exists the above problem, through market survey, the application range of rubber powder
Also very narrow, still lack the application approach of a large amount of consumption rubber powders.In addition, technique for regenerated rubber is complicated, big energy-consuming, production process is dirty
Contaminate environment
Invention content
To solve the above problems, the present invention provides a kind of Bridge Seismic constructions combined based on two-ash soil and waste tire
Method has not only reached the recycling of waste tire, protection ring using waste tire as a kind of novel culvert backfilling material
The problem of purpose in border, and alleviate the differential settlement of the bridge platform back of the body, effective solution " bumping at bridge-head ".
To achieve the above object, the technical solution that the present invention takes is：
A kind of Bridge Seismic construction method combined based on two-ash soil and waste tire, is included the following steps：
