Abstract

The utility model relates to an it jumps attachment strap structure of car to reduce abutment, including the attachment strap of connecting road bridge with set up the miniature stake under the attachment strap, the attachment strap is including flat attachment strap and ladder attachment strap, flat attachment strap setting is in the one end of nearly abutment, the setting of ladder attachment strap is in the basic one end of short cut, the ladder attachment strap links to each other with the road bed, the road bed tip is located ladder attachment strap top, be equipped with the isolation layer between road bed and the ladder attachment strap, ladder attachment strap below is provided with a plurality of miniature stakes of burying underground in the road bed soil layer, this constructs construction convenience, can show the problem that reduces the abutment and jump the car, it generally has the seam bridge also to can be used to seamless bridge simultaneously both to be applicable to, miniature stake has increased the vertical braces rigidity of short cut cardinal extremity attachment strap through arranging under the attachment strap, subsiding of road bed end attachment strap effectively reduce to be close to, biography masterpiece through miniature stake is used, with the upper portion load that the soil layer receives dispersion to the soil layer of lower part in, increase the scope of atress soil matrix, thereby reduce the stress of the neighbouring attachment strap department soil body, what prevent to banket under the attachment strap comes to nothing.

Description

Reduce the attachment strap structure of bump at bridgehead
Technical field
The utility model relates to a kind of attachment strap structure reducing bump at bridgehead, belongs to bridge field.
Background technology
Bumping at bridge-head refers to that the sedimentation inequality due to road and bridge causes, when the vehicle of running at high speed is by producing the phenomenon of porpoising during back filling behind abutment place.In China, vehicle bump at bridge ends is ubiquitous, and the road-bridge transition section of different sections of highway all more or less can exist vehicle bump at bridge ends.The existence of this phenomenon not only affects the comfort of driving, exacerbates the destruction to bridge structure thing simultaneously, adds road and bridge maintenance cost.And automobile is having to through end of the bridge reduce the speed of a motor vehicle, adds running time, reduces operational efficiency, may cause the generation of accident time serious in addition, seriously reduce service level and the traffic safety of speedway.
For vehicle bump at bridge ends, existing common practices repairs sedimentation road surface, but in the near future vehicle bump at bridge ends can occur again, carrying out repeatedly is keeped in repair and not only greatly wastes manpower and materials, and make troubles to the current of speedway, create bad social influence simultaneously, have impact on the normal trip of people.So the governing problem of vehicle bump at bridge ends has become the difficult problem of pendulum before various countries highway construction technician.
Utility model content
In view of the deficiencies in the prior art, technical problem to be solved in the utility model there is provided a kind of attachment strap structure reducing bump at bridgehead, this structure easy construction, significantly can reduce the problem of bump at bridgehead, both be applicable to general seamed bridge and also can be used for seamless bridge simultaneously.
In order to solve the problem, the technical solution of the utility model is: a kind of attachment strap structure reducing bump at bridgehead, draw together the attachment strap connecting road and bridge and the mini pile be arranged under attachment strap, described attachment strap comprises flat attachment strap and ladder attachment strap, described flat attachment strap is arranged on one end of nearly abutment, described ladder attachment strap is arranged on one end of shortcut base, described ladder attachment strap is connected with roadbed, Subgrade portion is positioned at above ladder attachment strap, be provided with separation layer between roadbed and ladder attachment strap, below ladder attachment strap, be provided with some mini piles be embedded in roadbed soil layer.
Further, described mini pile is concrete precast pile, and stake footpath is less than 400mm.
Further, described flat attachment strap and ladder attachment strap are that concrete formed by integrally casting is shaping.
Compared with prior art, the utility model has following beneficial effect: this structure easy construction, significantly can reduce the problem of bump at bridgehead, both be applicable to general seamed bridge and also can be used for seamless bridge simultaneously, by arranging that under attachment strap mini pile adds the vertical supporting rigidity of shortcut cardinal extremity attachment strap, effectively reduce the sedimentation near Subgrade attachment strap, by the intermal force of mini pile, upper soil horizon load is distributed in the soil layer of bottom, increase the scope of stressed soil matrix, thus reduce the stress of the contiguous attachment strap place soil body, that bankets under preventing attachment strap comes to nothing.
Accompanying drawing explanation
Fig. 1 is the organigram that the utility model is applied in seamless bridge;
Fig. 2 is the organigram that the utility model is applied in seamed bridge;
Fig. 3 is the floor map of attachment strap of the present utility model structure;
In figure: the flat attachment strap of 1-; 2-ladder attachment strap; 3-mini pile; 4-separation layer; 5-roadbed; 6-shrinkage joint; 7-bearing.
Detailed description of the invention
For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below.
As shown in Fig. 1 ~ 3, a kind of attachment strap structure reducing bump at bridgehead, draw together the attachment strap connecting road and bridge and the mini pile 3 be arranged under attachment strap, described attachment strap comprises flat attachment strap 1 and ladder attachment strap 2, described flat attachment strap 1 is arranged on one end of nearly abutment, described ladder attachment strap 2 is arranged on one end of shortcut base 5, described ladder attachment strap 2 is connected with roadbed 5, roadbed 5 end is positioned at above ladder attachment strap 2, separation layer 4 is provided with between roadbed 5 and ladder attachment strap 2, making between roadbed 5 and attachment strap can relative sliding, meet the needs of attachment strap and bridge main beam longitudinal strain, some mini piles 3 be embedded in roadbed soil layer are provided with below ladder attachment strap 2, increase the vertical supporting rigidity of shortcut cardinal extremity attachment strap, effectively reduce the sedimentation near Subgrade attachment strap.
In the present embodiment, described mini pile 3 is concrete precast pile, and stake footpath is less than 400mm.
In the present embodiment, described flat attachment strap 1 and ladder attachment strap 2 are that concrete formed by integrally casting is shaping.
Specific implementation process:
During construction, first prefabricated mini pile 3 at stake top reserved steel bar, the size according to mini pile 3 carries out prebored hole in roadbed soil layer, installs mini pile 3 more afterwards and tamping road bedly to banket.Finally by the reinforcement welding of mini pile 3 top reserved steel bar and attachment strap, carry out building of attachment strap.
The utility model is not limited to above-mentioned preferred forms, and anyone can draw the attachment strap structure of other various forms of reduction bump at bridgehead under enlightenment of the present utility model.All equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
