Description

Infiltration type powder mixer structure

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 infiltration type Powder mixer structure.

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.

CN105000845 disclose it is a kind of applied to Abutment Back backfill lightweight foam soil, including cement, mixing material, Water, conditioning agent, foaming agent, foaming agent, waterproofing agent；Additionally provide a kind of preparation of the lightweight foam soil applied to Abutment Back backfill By plunger pump and air compressor machine foam is made in foaming agent by method, material is mixed by blender, frequency converter control System takes out the speed of slurry, to control the unit weight of final finished；Additionally provide a kind of lightweight foam soil applied to Abutment Back backfill Component on site construction method, the utility model light foam penus light material is small to foundation load after filling, is greatly reduced at ground Intensity is managed, the basement process duration is saved.After lightweight foam soil cast before initial set, there is good mobility, fill self-compaction, it can Conventional fillers are avoided to fill not full defect, application property is strong, the phenomenon that capable of effectively solving bumping at bridge-head.

But the existing autochthonal forming apparatus of foam be it is complicated, and there are the liquid such as powder and water mixing it is uneven, Lead to small powder ball occur, then influences quality.
