Abstract

The invention relates to the field of road construction, in particular to a novel construction method aiming at the defects of the prior road and bridge construction technology. The method changes a seam required to be perpendicular to the road surface in the prior road construction into a seam which forms an angle of about 45 degrees with the road direction. The road and the bridge surface can be connected by a W-shaped seam. The method can greatly reduce the damage caused by the defects of the prior design to the road and vehicles and also reduce the influence of noise on the surrounding environment. The method has the advantages of simplicity, convenient application, convenient construction and scientific and reasonable design, greatly reduces the harm and influence on the roads, the bridges, the vehicles and the environment, prolongs the service life and brings profit to the country and the people.

Description

New job practices in the construction of road and bridge

Technical field:

What the present invention relates to is the highway construction construction field, new job practices in specifically a kind of construction of road and bridge.

Background technology:

Along with the high speed development of national economy and society, the construction of highway and development are also more and more, more and more faster.Because original outmoded, aging, narrow road and bridge can't be satisfied the current demand of more and more vehicles.Broad, smooth high-grade highway, the bridge newly made now constantly complete, are open to traffic, for vehicle driving brings great convenience, fast.Yet no matter be original old road, all owing to be subjected to the requirement of construction technology, when construction operation, be separated by between laying base water mud layer all is provided with the rule slit vertical with trend of road to still newly-built highway about ten meters.

So, just make highway after use, owing to be subjected to various vehicles, particularly large-scale loaded vehicle constantly rolls, add that construction quality is not absolutely all equally solid, the sedimentation that causes differ and construct in the slit globality of having cut off cement basic layer of design, make highway, bridge floor after having used a period of time, occur rugged phenomenon gradually at some seam crossing, vehicle is being clashed into and vibrations through out-of-date the generation each other, road pavement and vehicle cause further destruction and damage, and produce noise.And As time goes on become more and more serious, form vicious circle.

Shanghai Outer Ring north Zhai Lu mortise boccaccio section and being uneven of some other highway section are exactly the performance of this situation, many drivers drive through here the time, and the sensation car clashes into mutually as not stopping vibrations dancing, and send ringing of rumbling, influence is along road resident's life.Also have this old road of Cao An highway, Shanghai, the road surface situation is just even worse, and the other sleepy of resident that stays in the roadside feels to good, but is waken up with a start by the vibrations of vehicle in the depth of night through being everlasting and can not fall asleep.

Summary of the invention:

The present invention is exactly a kind of new construction of road and bridge job practices that designs at the problems referred to above of the deficiency appearance of existing construction technology.It can reduce greatly because of the damage of original design defect to highway, vehicle, can also reduce the influence of noise to surrounding environment.

The specific embodiment:

With require in the existing road construction with perpendicular slit, road surface change into road direction be slit about 45.Can select the crack method of attachment of " W " groove part for use at highway and bridge floor junction.Other construction technology methods are constant.Like this, vehicle is compared with the vertical slit of road direction when stitching by the road under the same conditions, because of new road seam be 45 ° oblique, make the right and left wheel on the same axle of vehicle not clash into simultaneously, and make shaking force and sound drop by half, and when a certain cincture tire contact slit not only because of its be 45 ° oblique but also make the shaking force and the sound drop by half of vehicle.That is to say that bump shaking force and sound that a wheel on the same axle of car produces have all descended more than the twice when stitching than vertical road through 45 ° of oblique road seams.And the same axle of vehicle when going up tire through 45 ° of oblique roads seams about wheel across the both sides, slit, thereby reduced a certain wing face moment bearing capacity.Thereby prolong road application life, reduce the impact damage of vehicle, reduce noise.

So the inventive method is simple, use easy, easy construction, design science is reasonable, greatly reduces road, bridge, vehicle, environmental hazard and influence, has prolonged application life, benefits the nation and the people.

Claims

1, the new constructure scheme in the construction of road and bridge is that road when construction cement basic layer seam crossing was oblique slit about 45 jiaos by becoming with road direction perpendicular to road direction originally, road and bridge junction " W " type that is designed to connect the slit, make vehicle when passing by on one's way seam, can reduce vibrations, reduce infringement, reduce noise.
