Description
Technical field
The utility model is related to road and bridge construction machinery, fast construction technical field of construction, more particularly to a kind of intermittent
Mixing apparatus of powdery row material.
Background technology
Bumping at bridge-head is made due to relative settlement or the expansion joint destruction at highway end of the bridge and expansion joint (bridge approach)
Road surface longitudinal slope occur step cause vehicle by when generate jump the phenomenon that, principle is that road surface difference occurs at back filling behind abutment
The sedimentation fracture (sedimentation value is generally 10~30cm, and some is even more than 60cm) of degree, make vehicle by when generate jump and
Impact makes driver and passenger feel discomfort of jolting, or even cause vehicle to cause additional impact load to bridges and culverts and road surface
Significantly slow down, it is serious to lead to traffic accident (especially vehicle mechanical accident).Therefore, problem of bumping at bridge-head has become height
The construction quality of standard highway and the important factor in order of cost.Problem of bumping at bridge-head is always to perplex municipal administration engineering technology
One of problem of personnel.It solves the problems, such as bumping at bridge-head, is the vital task of Municipal Infrastructure Management department
The main reason for causing bumping at bridge-head have differential settlement, rigidity mutation and speed and vehicle itself resistance to shock
Deng.For urban road road conditions, differential settlement, production occur for the junction mainly between flexible pavement and rigid structure
Caused by raw faulting of slab ends.Bridge and roadbed, the composition material on road surface, rigidity, intensity, swell-shrink characteristic etc. have differences, and end of the bridge junction
Concentrated stress is easily formed when stress.Under vehicular load, dead load, effect of natural environment, it is heavy that bridge occurs simultaneously with road
Drop, but the settling amount of the two has very big difference, the settling amount of road to be much larger than the settling amount of bridge, forms faulting of slab ends, causes to drive a vehicle
Shi Fasheng bumping at bridge-head.
