Abstract
Description
Technical Field
[0001] This utility model relates to the field of bridges and roads, and in particular to a new type of passageway utilizing railway bridge piers and U-shaped channels. Background Technology
[0002] Disadvantages of existing technologies: Roadbed construction typically relies on heavy machinery for site leveling, filling, and compaction. These operations directly compress or vibrate the surrounding soil, causing consolidation settlement around nearby high-speed railway bridge piles. This settlement generates negative skin friction on the bridge piles, increasing the vertical load on the piles and potentially leading to pile cracking and reduced bearing capacity. Roadbeds are generally loose structures, and their self-weight and vehicle loads are unevenly transferred to the foundation through the roadbed fill material. This uneven load transfer can cause excessive local stress on the foundation, leading to differential settlement and subsequent road surface cracking, reduced smoothness, and other defects, affecting road safety and service life. Roadbeds typically use conventional fill materials such as soil and rock, which are heavy and place high demands on the foundation's bearing capacity. In areas with insufficient foundation bearing capacity, complex treatments such as replacement and reinforcement are required, significantly increasing project costs and time.

[0005] The purpose of this utility model is to provide a new type of passageway that makes better use of railway bridge piers and U-shaped channels. The specific purpose is explained in the specific implementation section for several substantial technical effects.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A novel passageway utilizing railway bridge piers and U-shaped channels, characterized in that...
[0008] The new traffic lane includes an oncoming vehicle side 1 and an outgoing vehicle side 2;
[0009] The approaching vehicle side 1 and the departing vehicle side 2 pass through the railway bridge pier 3;
[0010] The approaching vehicle side 1 and the outgoing vehicle side 2 each include the road surface, and a U-shaped trough 4 is arranged under the road surface;
[0011] Above the U-shaped channel 4, there is a galvanized wire mesh 7, a layer of bubble-mixed lightweight soil 6, and a road surface.
[0012] A further technical solution of this utility model is that the structure of the U-shaped groove 4 includes a flat part at the bottom, inclined parts connected to both sides of the flat part, and higher flat parts connected to the inclined parts. The higher flat parts extend out of a vertical wall, and the baseline of the road edge is arranged on the vertical wall.
[0013] A further technical solution of this utility model is that the U-shaped groove 4 has a symmetrical structure.
[0014] A further technical solution of this utility model is that the landfill soil on the vehicle side 1 and the vehicle side 2 contains pipes, which are sewage pipes, water supply pipes and heating pipes.
[0015] A further technical solution of this utility model is that a water supply pipe and a sewage pipe are buried in the vehicle side 1. The water supply pipe is made of DN200 polyethylene pipe, and a 300x10 anti-corrosion steel pipe sleeve is installed on its outer side. The gap between the pipe and the sleeve is filled with sand grouting. The sewage pipe is made of DN600 steel strip reinforced polyethylene spiral corrugated pipe, and a 0800x13 anti-corrosion steel pipe sleeve is installed on its outer side. The gap between the pipe and the sleeve is filled with sand grouting.
[0016] A heating pipe is buried inside the vehicle side 2. The heating pipe is used for water supply and return. The heating pipe is made of DN400 steel pipe. A rigid polyurethane foam insulation layer and PE protective pipe are installed on the outside. A 700x13 anti-corrosion steel pipe sleeve is installed. A gap of not less than 50mm is left between the pipe and the sleeve.
[0017] A further technical solution of this utility model is that an inclined concrete drainage layer 10 is arranged on the side away from each other on the side of the vehicle coming side 1 and the side of the vehicle going side 2, and a layer of original rammed soil is arranged below the concrete drainage layer 10.
[0018] The present invention, employing the above technical solution, offers the following advantages over existing technologies: The "U"-shaped channel eliminates the need for large-scale mechanical compaction, avoiding disturbance to the soil surrounding the bridge piles from the construction stage and protecting the stability of the high-speed railway bridge foundation. As a rigid integral structure, the "U"-shaped channel concentrates and evenly transfers loads to the foundation, preventing localized stress concentration and reducing the risk of foundation deformation. Lightweight materials such as EPS can be filled inside the "U"-shaped channel, significantly reducing the overall structural weight and thus decreasing the demand on foundation bearing capacity, allowing the project to meet requirements without excessive foundation treatment.

A rigid polyurethane foam insulation layer and PE protective pipe are installed on the outside. A 700x13 anti-corrosion steel pipe sleeve is installed. A gap of not less than 50mm is left between the pipe and the sleeve.
[0043] Example 6: As a further improvement, parallel, or optional independent solution, an inclined concrete drainage layer 10 is arranged on the side away from each other on the approaching vehicle side 1 and the departing vehicle side 2, and a layer of original rammed soil is arranged below the concrete drainage layer 10.
