Description

Technical Field

[0001] This utility model relates to the field of retaining structures, specifically a retaining structure for a bridge abutment of a cross-river bridge. Background Technology

[0002] With the development of society, retaining walls have been widely used. Retaining structures for greening in water conservancy projects refer to structures that support roadbed fill or hillside soil and prevent deformation and instability of the fill or soil, thereby improving the stability of roadbed fill or hillside soil.

[0003] Bridge abutment retaining structures are a crucial component of bridge engineering, primarily used to support the bridge superstructure, connect roads on both banks, and withstand the backfill pressure behind the abutment, ensuring the stability of the roadbed at the bridgehead. However, due to heavy rainfall in recent years, the soil layers on both sides of the abutment are easily eroded, leading to soil loss and landslides. To address this issue, we propose a bridge abutment retaining structure for cross-river bridges. Utility Model Content

[0004] To address the existing problems, this utility model provides a retaining structure for a bridge abutment of a cross-river bridge, which can effectively solve the problems mentioned in the background art.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A retaining structure for a bridge abutment of a cross-river bridge includes a soil layer, a bridge body erected on the left side of the soil layer, a road surface paved on the upper surface of the soil layer, a paving component laid on the front side of the soil layer, a covering component laid on the outer surface of the paving component, multiple reinforcing components installed on the upper surface of the covering component, a connecting component installed on the outer surface of each reinforcing component, a protective component installed on the upper surface of the paving component, an auxiliary component on the front side of the paving component, and a drainage component laid below the paving component.

[0007] As a further embodiment of this utility model: the laying component includes a retaining frame, the retaining frame is located on the outer surface of the soil layer, and a first layer of stones is laid inside the retaining frame.

[0008] As a further embodiment of this utility model: the covering component includes a covering stone slab, the covering stone slab is located on the outer surface of the first stone layer, and the outer surface of the covering stone slab is provided with a plurality of grid grooves.

[0009] As a further embodiment of this utility model: the reinforcement component includes a plurality of first fixing blocks, each of the first fixing blocks being located on the outer surface of the retaining frame, each of the first fixing blocks having a reinforcement plate installed on its upper surface, each of the reinforcement plates having a second fixing block installed at its top, and the bottom surface of each of the second fixing blocks being in contact with the upper surface of the retaining frame.

[0010] As a further embodiment of this utility model: the connecting component includes two connecting blocks, both of which are located on the outer surface of the retaining frame, and a steel wire rope is installed between the two connecting blocks, the steel wire rope being connected to multiple reinforcing plates.

[0011] As a further improvement of this utility model: the protective component includes multiple support rods, each of which is located on the upper surface of the retaining frame, and a protective plate is installed at the top of each of the support rods.

[0012] As a further embodiment of this utility model: the auxiliary components include a ladder and a guardrail, both of which are located on the outer surface of the retaining frame.

[0013] As a further embodiment of this utility model: the drainage component includes a drainage channel, which is located below the laying component, and a second layer of stones is laid inside the drainage channel.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This retaining structure for a bridge abutment of a cross-river bridge covers the soil layers on both sides of the abutment by laying a retaining frame on the outer surface of the soil layers and laying a first layer of stones inside the retaining frame, thereby preventing the soil layers from being washed away by rainwater. Furthermore, with the cooperation of covering components, reinforcing components, and connecting components laid on the outer surface of the first layer of stones, the inner first layer of stones can be protected to prevent rainwater from scattering the stones. Therefore, this device effectively solves the problem of soil loss caused by rainwater erosion, which leads to landslides on both sides of the abutment. Attached Figure Description
