Abstract
The utility model relates to a high earth-filled road-bed stage back capable of preventing vehicle vibration on bridge head, consisting of pile, calx sand bag, filling and roadbed. The bottom of the stage back is to arrange the calx sand bags tail to head along the transverse roadbed direction and arrange the calx sand bags in a bias with an upper part is wider than the lower part along the longitudinal roadbed direction; the calx sand bags are arranged crossly and are gradually reduced layer after layer; thus, the calx sand bags are almost positioned in a shape of right-angle triangle. The space of the stage back and the calx sand bag are filled with filling of stage back. The high earth-filled road-bed stage back built with the method of the utility model can completely avoid the natural sinking of the stage back, solving the problem of vehicle vibration on bridge head.
Description
The utility model belongs to a kind of novel platform back of the body structure body.
The speedway that the whole nation puts into effect surpasses 10,000 kilometers, and these highways mostly are that country is the pulling economic development in recent years, build in the input process of increasing to infrastructure constructions such as highways.Because higher construction period of roadbed of highway is shorter, occur end of the bridge letter top after being open to traffic mostly in varying degrees and jumped the car phenomenon, particularly serious at high fill, soft foundation highway section.This has not only influenced running velocity, driving comfort, and some places even cause the fault and the traffic accident of vehicle become and are badly in need of the significant problem that solves in speedway and high fill highway construction and the operation.At this situation, many insiders further investigate this, have proposed the measure of prevention and punishment bumping at bridge-head.
Consulting data such as relevant specification, treatise and construction experience introduction can see, the material of current high filling subgrade platform back of the body structure body mainly contains: material that can the certain intensity of fixed formation, as rendzinas, cement-soil, comprehensive stable soil etc.; The material that is difficult for deforming is as sand, stone etc.; Light material is as coal powder etc.Above material is applicable to various occasion, all can obtain the effect that reduces the sedimentation of the platform back of the body greatly.But because bridge belongs to two kinds of different structures with roadbed, the platform back of the body, the former face of land of any roadbed or the platform back of the body all can not have the pile or the peculiar stability of pier of bridge; The filler of any roadbed, the platform back of the body also can not have peculiar rigidity of bridge construction and stability.This just makes with regard to the relative bridge that the sedimentation that compressive strain caused of the sedimentation on the former face of land of high filling subgrade and roadbed, platform back of the body filler self is an inevitable irreversible trend.
Platform back of the body structure body before the utility model all is horizontal filler, and material all is layering or uses with, is difficult to prevent and offset the natural subsidence of the former face of land and filler self, thereby makes bumping at bridge-head become the ubiquitous problem of high filling subgrade.
Task of the present utility model is: provide a kind of can easy construction, can offset the platform back of the body structure body of platform back of the body sedimentation again on demand, the natural subsidence of the platform back of the body is controlled effectively, thoroughly solve problem of bumping at bridge-head.
The method that the utility model task solves is: the platform back of the body structure body near bridge floor is made up of pile, quicklime sand pocket, filler, road surface, platform back of the body structure body bottom joins end to end the quicklime sand pocket and puts in a row by cross road base direction, become low wide and up narrow oblique line by vertical roadbed direction by roadbed one side-sway, each layer cross arrangement, successively successively decrease, form the approximate right angle triangle, carry on the back for whole and fill platform back of the body filler between space and the quicklime sand pocket.
The quicklime sand pocket is with the plastic woven cloth of uncoated suitable density.Carry on the back on the basis at the platform of handling well, join end to end by cross road base direction spacing 5～100cm with this quicklime sand pocket that ties mouth and put in a row.
By the direct backfilled roadbed supported material of road surface one end.After the quicklime sand pocket added in the back filling behind abutment material, because it can not be directly contact with moisture in the filler, thereby does not influence the water content and the compacting of filler, and the quicklime sand pocket after the compacting had the compactness close with filler.With the slow immersion of moisture, quicklime is slowly cleared up in the process of subgrade settlement, and volume slowly increases.Raise as meeting water level therebetween, subgrade moisture content increases, and causes subgrade settlement to speed up, and then the expansion of quicklime is also accelerated synchronously, thereby has offset the sedimentation of the platform back of the body.Because nearly end of the bridge direction has been added the quicklime sand pocket of sufficient amount, can produce enough swell incremenies,, thereby make its former absolute altitude remain unchanged in order to all sedimentations of the low platform back of the body that disappears.The quicklime sand pocket of end of the bridge direction far away reduces gradually, and its swell increment also reduces gradually, and the ability of offsetting sedimentation weakens gradually, until the settling amount near roadbed, thereby has produced effect from end of the bridge to the mild transition of roadbed, makes to jump the car phenomenon and be resolved.Lime can form than hard intensity after expand finishing with making mixing of mineral aggregate, keeps the globality and stability of backfilling material.
Accompanying drawing is an embodiment of the present utility model.
Accompanying drawing 1 is the platform back of the body longitudinal sectional view of prevention car jump between high road bed and bridge.
Accompanying drawing 2 is the platform back of the body transverse sectional view of prevention car jump between high road bed and bridge.
Accompanying drawing 3 is the quicklime sand pocket sectional view of prevention car jump between high road bed and bridge.
As shown in Figure 1: 1 pile, 2 lime sand pockets, 3 fillers, 4 road surfaces.
Embodiment: long 20 meters, wide 25 meters of the platform back of the body, at first handle platform back of the body roadbed well, laterally accomplishing fluently a plurality of piles 1 near the bridge floor place, laterally put the quicklime sand pocket 2 that installs in the beginning of roadbed bottom then, put the quicklime sand pocket near on the pile one side straight line, lean on roadbed one adnation lime sand pocket successively to successively decrease and put into low wide and up narrow oblique line, the cross arrangement of each layer of quicklime sand pocket, regard the approximate right angle triangle as from the longitudinal profile of roadbed, carry on the back for whole and fill platform back of the body filler 3 between space and the quicklime sand pocket, complete road surface 4 topmost.Make the high filling subgrade platform back of the body of building in this way thoroughly eliminate the natural subsidence of the platform back of the body, thereby solved the problem of bumping at bridge-head.
Claims (1)
1, the platform back of the body of prevention car jump between high road bed and bridge, the platform back of the body near bridge floor is made up of pile, quicklime sand pocket, platform back of the body filler, road surface, in the platform handled well the back of the body bottom quicklime sand pocket joined end to end by cross road base direction and to put in a row, become low wide and up narrow oblique line by vertical roadbed direction by roadbed one side-sway, each layer cross arrangement of quicklime sand pocket successively successively decreased, form the approximate right angle triangle, it is characterized in that having put quicklime sand pocket from bottom to top in the platform back of the body.
