Description

Technical Field

[0001] The utility model belongs to the technical field of building engineering construction, in particular to a bridge pile-row abutment supporting structure. Background Art

[0002] In the Chinese utility model patent: the authorization announcement number CN204551242U, the utility model relates to a novel semi-rigid abutment structure, including supporting piles, abutments are arranged above the supporting piles, a supporting belt is arranged between the abutments and the supporting piles, at least one row of force transmission rods are arranged at intervals along the length direction of the abutments and the supporting piles, and the force transmission rods penetrate the supporting belts and connect the supporting piles and the abutments up and down. The utility model changes the rigid connection form of the traditional seamless bridge at the connection between the piles and the abutments. By setting force transmission rods, the connection between the abutments and the pile foundation is designed to be rotatable and hinged, which effectively avoids the problem of plastic hinges formed in the high stress area at the connection caused by cyclic loads in traditional seamless bridges, avoids large lateral displacement of the pile foundation and affects the bearing capacity of the pile foundation, and also avoids the problem of fatigue fracture of steel bars caused by incomplete hinge connection between the piles and the abutments, effectively improving the safety performance of seamless bridges.

[0003] With the increasing efforts in infrastructure construction, the construction of bridges or underground spaces has been accelerated. The implementation of many bridge projects requires both support for the existing soil and construction of abutments at corresponding locations. The traditional approach is to excavate first and then construct, which has complicated procedures and increased costs. This is especially difficult to implement for new and reconstruction projects that require the construction of bridges on the existing roadbed and cannot be done through large-scale excavation and filling. Utility Model Content

[0004] The utility model provides a bridge pile abutment support structure, aiming to solve the problem that the traditional method is to excavate first and then construct, which is complicated in process and increases in cost. In particular, it is difficult to carry out the traditional method for constructing bridges on the existing roadbed and for new construction and reconstruction projects where large excavation and large filling are not possible. The utility model is implemented as follows: the bridge pile abutment support structure includes reinforced concrete piles: the outer wall of the reinforced concrete piles has plain concrete piles, the tops of the reinforced concrete piles and the plain concrete piles are provided with crown beams, and one side of the reinforced concrete piles and the plain concrete piles is provided with a reinforced concrete retaining wall;

[0005] Wherein, a lower channel is arranged on one side of the reinforced concrete retaining wall.

[0006] Preferably, a bridge beam body is arranged on the top of the crown beam, and a backfill layer is arranged on one side of the crown beam.

[0007] Preferably, there are multiple rows of reinforced concrete piles and rows of plain concrete piles, and the multiple rows of reinforced concrete piles and rows of plain concrete piles are arranged to interlock with each other.

[0008] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0009] 1. The design of the utility model avoids the large-scale excavation and filling required by the commonly used abutment types of bridges, has a small impact range, a short construction period, and saves engineering costs, thereby solving the problem of material waste in existing construction methods and being more environmentally friendly and energy-saving.

[0010] 2. The design of the utility model has high utilization efficiency of reinforced concrete interlocking pile components, meets the relevant requirements such as backfill and water stopping behind the support platform, and the exterior finishing surface is coordinated with the surrounding environment, meeting the aesthetic requirements.

[0011] 3. With the help of limited construction space, the use of integrated pile abutments greatly shortens the construction time, eases traffic capacity, facilitates construction, and shortens the construction period.

[0012] In summary, the utility model of a bridge pile abutment support structure at a roadbed or underground space can achieve: economically reducing the project cost, shortening the project period, environmentally conducive to aesthetic requirements, and functionally serving two purposes with one pile.
