Abstract
One kind improvement transition segment structure, the structure includes abutment, geotechnical grid, abutment connector, geotechnical grid connector, coupling bar；Several geotechnical grids are provided between abutment and roadbed bottom surface；The end of geotechnical grid is provided with geotechnical grid connector；Abutment connector is fixed on the side of abutment；Geotechnical grid connector is articulated and connected with abutment connector by coupling bar.Trapezoidal soft patch is the stereochemical structure and reinforcement mechanism using geotechnical grid back-up coat, form the larger flexible structural layer of good integrity, rigidity, using modulus gradual change principle, ground and roadbed two parts settlement factors are considered simultaneously, in road-bridge transition section, trapezoidal stabilization zone is set, one section of flexible structural layer is fixed on abutment, the other end is connected with roadbed, realize the smooth transition of rigid abutment and flexible subgrade modulus, eliminate excessive differential subsidence, smoothly sedimentation changeover portion is formed, reaching prevents the purpose of bump at bridgehead.
Description
Technical field
The utility model belongs to field of civil engineering, and in particular to a kind of use hazard to bridge's pier eliminates the improvement road and bridge for jumping car
The construction method of transition section structure.
Background technology
Road-bridge transition section is the multiple location of road disease, is the problem for perplexing highway construction.Abutment and embankment rigidity phase
Poor great disparity, uneven deformation of two kinds of materials inside and out various under the influence of factor is inevitable.By making abutment structures
Gradual change is obtained in the certain limit of approach embankment so that modified difference gradual change within the specific limits with the poor rigidity of embankment, it is ensured that
Any point poor rigidity after gradual change will not cause jump car, be finally reached the purpose for eliminating bumping at bridge-head.
Utility model content
The purpose of this utility model is to provide a kind of construction method of effective improvement transition segment structure, eliminates because jumping car
The traffic safety hidden danger brought and the influence to structure.
The technical scheme that the utility model is used is：One kind improvement transition segment structure, the structure include abutment 1,
Geotechnical grid 2, abutment connector 3, geotechnical grid connector 4, coupling bar 5；Several geotechniques are provided between abutment 1 and roadbed bottom surface
Cell compartment 2；The end of geotechnical grid 2 is provided with geotechnical grid connector 4；Abutment connector 3 is fixed on the side of abutment 1；Geotechnological lattice
Room connector 4 is articulated and connected with abutment connector 3 by coupling bar 5.
The cell compartment of geotechnical grid 2 is trapezoidal.
Each top-down spacing of geotechnical grid 2 gradually increases, and length is gradually shortened.
Geotechnical grid 2 can be replaced with GSZ.
Trapezoidal soft patch be using geotechnical grid back-up coat stereochemical structure and reinforcement mechanism, formed good integrity, just
The larger flexible structural layer of degree, using modulus gradual change principle, while ground and roadbed two parts settlement factors are considered, in road and bridge mistake
Cross section and trapezoidal stabilization zone be set, one section of flexible structural layer is fixed on abutment, and the other end be connected with roadbed, realization rigidity abutment with it is soft
Property subgrade modulus smooth transition, eliminate excessive differential subsidence, form smoothly sedimentation changeover portion, reaching prevents that abutment from jumping
The purpose of car.
Brief description of the drawings
Fig. 1 is the schematic diagram of the geotechnical grid structure between abutment and roadbed bottom surface.
Fig. 2 is the application drawing of this structure.
In figure：1st, abutment；2nd, geotechnical grid；3rd, abutment connector；4th, geotechnical grid connector；5 coupling bars；
Embodiment
As shown in Figure 1-2, a kind of improvement transition segment structure, by being set in abutment and roadbed binding site from upper
Under the trapezoidal geotechnical grid or GSZ that gradually decrease, realize the rigid-flexibility transition of abutment and roadbed.
Geotechnical grid or GSZ near the roadbed bottom lay, top-down spacing gradually increases, length
It is gradually shortened.
Geotechnical grid or GSZ are hinged with abutment by montage device, it is ensured that it keeps continuous with abutment.
