Description
Technical Field
The utility model relates to the technical field of bridges, in particular to a light abutment structure.
Background
Bridge abutment, which is located at two ends of bridge and is a structure for supporting the upper structure of bridge and connecting with embankment. The bridge head road bed has the functions of resisting the filling pressure after the bridge, stabilizing the bridge head road bed and ensuring that the bridge head line and the bridge upper line are reliably and stably connected besides the function of transferring the load of the bridge upper structure to the foundation.
At present, the complex installation of structure exists between bridge and the abutment loaded down with trivial details problem of installation, simultaneously, the vehicle can produce slight displacement to the bridge in the in-process of traveling on the bridge, and the tired connection that can make between bridge and the abutment takes place to loosen easily in daily accumulation moon, causes the potential safety hazard to the life of bridge has been shortened.
Disclosure of Invention
The utility model aims to solve the technical problems, and provides a light bridge abutment structure, which can simplify the installation and fixing structure between a bridge and an abutment, improve the installation efficiency between the bridge and the abutment, increase the connection strength between the bridge and the abutment, reduce the displacement of a vehicle on the bridge and prolong the service life of the bridge.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a light-duty abutment structure, includes abutment and bridge, the top of abutment is provided with spacing wall and support platform, the spacing wall sets up along vertical direction, the support platform sets up along the horizontal direction, form L shape installation position between spacing wall and the support platform, the tip fixed mounting of bridge is on L shape installation position, be provided with the rubber pad support on the spacing wall, the tip lateral wall of bridge is hugged closely on the rubber pad support and is fixed through the bolt, be provided with the steel sheet support on the support platform, the tip diapire of bridge is hugged closely on the steel sheet support and is fixed through the bolt.
As a further improvement of the utility model, the abutment further comprises an abutment bottom plate, and the abutment bottom plate are connected to form a vertical L-shaped structure for backfill covering.
As a further improvement of the utility model, the bottom of the abutment bottom plate is provided with anchoring steel bars.
As a further improvement of the utility model, the abutment is a reinforced concrete structure.
The beneficial effects of the utility model are as follows: an L-shaped installation position is formed between the limit wall and the support platform on the bridge abutment, and the bridge can be installed on the bridge abutment through bolts. Meanwhile, the rubber pad support is arranged on the limiting wall, so that horizontal displacement of the bridge caused by a buffer car when the car is braked can be limited, the steel plate support is arranged on the support platform, the up-down displacement of the bridge is controlled while the connection strength is ensured, the rubber pad support and the steel plate support are combined, the displacement of the car to the bridge can be effectively reduced, and the service life of the bridge is prolonged.
Drawings
FIG. 1 is a schematic diagram of the overall structure of the present utility model;
marking: abutment 1, bridge 2, spacing wall 3, support platform 4, abutment bottom plate 5, rubber pad support 6, steel sheet support 7, anchor reinforcing bar 8.
Detailed Description
The utility model will be further described with reference to specific examples and figures.
As shown in fig. 1, a lightweight bridge abutment structure includes an abutment 1 and a bridge 2. The abutment 1 is a reinforced concrete structure, and the abutment 1 comprises a limiting wall 3 at the top, a support platform 4 and an abutment bottom plate 5 at the bottom. The limiting wall 3 is arranged along the vertical direction, and a rubber pad support 6 is arranged on the side wall of the limiting wall. The support platform 4 is arranged in a horizontal direction, and the top of the support platform is provided with a steel plate support 7. An L-shaped installation position is formed between the limiting wall 3 and the support platform 4. The bridge 2 adopts an I-shaped steel structure, a screw hole is formed in the end portion of the bridge 2, the end portion of the bridge 2 is fixedly installed on an L-shaped installation position, specifically, the side wall of the end portion of the bridge 2 is tightly attached to a rubber pad support 6 and is fixed through bolts, the horizontal displacement of the bridge 2 during running brake is limited, and the bottom wall of the end portion of the bridge 2 is tightly attached to a steel plate support 7 and is fixed through bolts, so that the vertical displacement of the bridge 2 is limited. The abutment 1 is connected with the abutment bottom plate 5 to form a vertical L-shaped structure for backfill covering, and the bottom of the abutment bottom plate 5 is provided with an anchoring steel bar 8, and the anti-overturning force is enhanced through the anchoring steel bar 8, so that the length and thickness of the abutment bottom plate 5 can be reduced.
During construction of the bridge abutment 1 structure, firstly, 1-meter deep pits with the size of the surface of the bridge abutment bottom plate 5 are dug at corresponding positions on two sides of the bridge 2, a cushion layer with the thickness of 10cm of C20 concrete is poured on the bottom surface of the pits, reinforcing steel bars are arranged on the cushion layer, anchoring reinforcing steel bars 8 are driven in, templates are erected, then concrete is poured on site to form the bridge abutment structure, and finally backfill soil covering is carried out on the side of the vertical L-shaped structure between the bridge abutment 1 and the bridge abutment bottom plate 5.
The above embodiments are only for illustrating the present utility model, and are not to be construed as limiting the utility model in any way, and any person having ordinary skill in the art will realize that equivalent embodiments of partial changes and modifications can be made by using the disclosed technology without departing from the scope of the technical features of the present utility model.
