AI Technical Summary
The hole-forming method of the drainage trough at the bottom of the existing bridge guardrail causes cracks and falling concrete blocks on the surface, and easily creates safety hazards when removing the steel blocks, affecting the project quality and construction efficiency.
Hard rubber embedded parts are used as embedded parts of the drainage trough. They are designed as step-shaped structures with slight elasticity. They can be quickly demoulded after concrete pouring to ensure the quality of the holes without cracks and falling pieces. The water grate is installed by embedding.
It improves the appearance quality of concrete, ensures the hole quality of drainage troughs, reduces the repair work during construction, avoids safety hazards during train operation, and improves construction efficiency and project quality.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge embedded parts, in particular to a hard rubber embedded part for bridge guardrails. Background Art
[0002] Drainage grooves measuring 15 x 20 cm are installed at regular intervals at the bottom of high-speed railway bridge guardrails to drain rainwater and other moisture accumulated on the bridge surface. If not drained in time, it will damage the bridge structure.
[0003] Currently, fixed-size steel blocks are used to create holes for drainage channels at the bottom of bridge guardrails. Removal of these blocks can easily cause cracks and falling blocks around the channels, leading to quality issues such as repairs. Repairs can also cause color variations on the concrete surface. After commissioning, train vibrations can cause the repaired parts to fall off, posing a safety hazard. This new design uses hard rubber embedded parts, which are easy to install and remove quickly. The holes created after concrete pouring are high-quality, eliminating the need for secondary repairs and significantly saving labor and material costs. Utility Model Content
[0004] The purpose of the utility model is to provide a hard rubber embedded part for bridge guardrail, which can effectively improve the appearance quality of concrete, ensure the quality of drainage trough holes and improve construction efficiency.
[0005] The present invention adopts the following technical solutions to achieve the above-mentioned purpose:
[0006] A hard rubber embedded part for a bridge guardrail, comprising a plurality of hard rubber embedded parts for forming drainage troughs and serving as mounting slots for water grates; the plurality of hard rubber embedded parts are arranged at intervals; each hard rubber embedded part is embedded in the bottom of the guardrail before concrete pouring; the hard rubber embedded parts have a stepped structure, i.e., the hard rubber embedded parts comprise a square block for forming the drainage trough and a chassis integrally formed with the square block; the chassis is located at the bottom of the square block, and its size is consistent with that of the water grate.
[0007] The hard rubber embedded part is a slightly elastic hard rubber embedded part.
[0008] The utility model proposes a hard rubber embedded part for a bridge guardrail. The hard rubber embedded part itself has a certain micro-elasticity and can be quickly demoulded after the concrete of the bridge guardrail is poured. The drainage trough has high hole quality, no cracks, and no falling blocks, and no secondary repair is required. The hard rubber embedded part can improve construction efficiency, effectively avoid risks during train operation, and ensure project quality. The utility model has the characteristics of simple structure, easy operation, and saving trouble and labor. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention will be described in detail with reference to the accompanying drawings and specific embodiments:
[0013] like Figure 1 As shown, a hard rubber embedded part for a bridge guardrail includes a plurality of hard rubber embedded parts 3 for forming drainage troughs; the hard rubber embedded parts 3 are arranged at intervals; each hard rubber embedded part 3 is embedded in the bottom of the guardrail 1 before concrete is poured; the hard rubber embedded part 3 is a stepped structure, that is, the hard rubber embedded part comprises a square block 3-1 for forming the drainage trough and a chassis 3-2 integrally formed with the square block; the chassis 3-2 is located at the bottom of the square block 3-1, and the size of 3-2 is larger than that of the square block 3-1; the size of the chassis 3-2 is consistent with the size of the drainage grate. After the guardrail concrete is poured, the hard rubber embedded parts 3 are removed, and the drainage trough 2 is finally formed integrally; and the water grate is installed in the slot formed by the embedded part chassis 3-2.
[0014] The hard rubber embedded part itself has a certain micro-elasticity, which is convenient for demoulding after concrete pouring and ensures the quality of hole formation.
[0015] By pre-embedding and the embedded parts themselves having a certain degree of micro-elasticity, the bridge guardrail can be quickly demoulded after the concrete is poured, and the water trough holes are of high quality, without cracks or falling pieces, and no secondary repair is required; the hard rubber embedded parts can improve construction efficiency, effectively avoid risks during train operation, and ensure project quality; the utility model has the characteristics of simple structure, easy operation, and saving time and effort.
