The present invention relates to the job practices of a kind of highway structure and maintenance, the job practices of particularly a kind of road bridge and highway junction.
At present, the job practices of road bridge and highway junction has two kinds usually, and a kind of is in their junction attachment strap to be set, and makes the stronger rigidity hardness of road bridge end carry out the transition to the less position of highway subgrade rigidity naturally by attachment strap.Another kind is to fill high-intensity building materials at the abutment back of road bridge, also makes the transition of rigidity nature.Though the former has avoided the weak link of the degree of compaction deficiency of bridge circuit junction, but As time goes on, the consolidation settlement of roadbed or because the variation of the traffic volume and traffic load can cause the deformation of the transition slab at bridge head generation longitudinal grade of junction, can make vehicle produce slight vibration during beginning, grow in intensity later on, abutment is produced impact, strengthened the inside separation trend of junction, the integral waterproofing performance is descended, occur the bumping at bridge-head disease then.Though the latter delays to some extent to the consolidation settlement of junction, but its long construction period, time-consuming, cost increases, and still can't change the trickle sedimentation of abutment self and the driving irregularity that brings impacts, be the difference of the own density of backfilling material and the seepage of water problem brought finally can cause the generation of bumping at bridge-head disease very soon.
In addition, for building up current highway bridge, if the jumping car disease of bridge circuit junction takes place, then be that surface material is adjusted road surface longitudinal gradient and absolute altitude or take measures (as by suitably replenishing roadbed material) improves the draining of abutment and roadbed junction by overlaying year by year, thereby improve the influence of bumping at bridge-head disease.This method construction is loaded down with trivial details, need suspend traffic and just can carry out, and need often to reinforce repeatedly, and is consuming time, and effect is still undesirable.
Purpose of the present invention is exactly in order to address the above problem, and proposes a kind of job practices that solves the bridge circuit junction of highway bridgehead vehicle jump disease.
Technical solution of the present invention:
A kind of job practices that solves the bridge circuit junction of highway bridgehead vehicle jump disease is characterized in that:
A, compacting is carried out in layering to the bridge of bridge circuit junction back of the body backfilling material;
B, squeeze into many friction piles in the transition region of bridge circuit junction, it is whole to make the junction soil body and friction pile constitute carrying;
C, between the abutment of end of the bridge and junction top course material, waterproofing materials is set;
D, epoxy concrete or steel disk are set, they are become one, so that each friction pile and effective combination of junction top course material at each friction pile top of squeezing into;
E, above-mentioned bridge circuit junction integral body is carried out pavement forming.
The inventive method integrates the advantage of attachment strap method and backfill high-strength material method, and overcome the defective that they exist separately, and its construction technology is simple, short construction period, and cost is low, and is effective.The inventive method has solved the problem of waterproof, the conversion of hard and soft property and the degree of compaction deficiency of bridge circuit junction, delayed subgrade settlement, pavement loading and driving load more are evenly distributed among the soil body of whole junction roadbed, effectively prevented the early stage generation of bumping at bridge-head disease, stabilized the impact that this disease is brought to the end of the bridge abutment, significantly reduce the highway maintenance workload, improved riding qualities.The inventive method is not only applicable to the new bridge construction, is equally applicable to the reconstruction and the maintenance of old bridge.
Description of drawings:
Fig. 1 is the structural representation that the inventive method is used for newly-built bridge construction.
