An embankment structure and filling method for reducing the incidence of vehicle jumping at the bridge head

Abstract

The invention discloses an embankment structure and a filling method for reducing the occurrence rate of vehicle jumping at the bridge head, wherein the embankment structure includes a cushion layer, a stone layer, an anti-vehicle layer, and a buffer layer arranged in sequence; the anti-vehicle layer includes several The anti-jump unit and the filler filled around the anti-jump unit and between adjacent anti-jump units; the anti-jump unit includes a perforated pipe body covered with geotextiles on the outer periphery, and a certain number of perforated pipe bodies are connected The geogrid together, and the filler that fills the periphery of the perforated pipe body. The filling method includes clearing the site; laying the embankment cushion; laying the filler layer, and laying the geogrid on the layer; placing the porous pipe body covered with the geotextile on the geogrid; The grid is wound on a certain number of perforated pipe bodies; after repeating step 5 several times, filling soil and rocks as a buffer layer; compacting. The invention has the advantages of simple and convenient construction, low cost, high economic benefit, good drainage conditions, environmental protection and saving, and the like.

Description

technical field [0001] The invention relates to road and bridge engineering, in particular to an embankment structure and a filling method for reducing the incidence of vehicle jumping at the bridge head. Background technique [0002] Vehicle jumping at the bridge head is currently a common problem of road quality in my country. The vehicle jumping at the bridge head refers to the inconsistency between the settlement of the bridge abutment and the embankment at the junction of the bridge and the embankment, which leads to a wrong platform at the bridge head, causing the vehicle to drive in this position. Bumps and jumps occur. Especially with the rapid development of my country's high-grade highways in recent years, the phenomenon of vehicle jumping at the bridge head is particularly common. [0003] In view of the problem of vehicle jumping at the bridge head, there are two main existing treatment methods: one is to increase the strength of the bridge head foundation, mainl...

AI Technical Summary

Problems solved by technology

[0004] The above method can solve the problem of jumping at the bridge head to a certain extent, but it also has its own shortcomings and deficiencies

For example, for the first type of disposal method, its construction is complicated, the cost is high, and the construction period is long, which has its shortcomings in terms of economic benefits

For the second type of disposal measures, in actual engineering, due to the limitations of construction and maintenance, it is still very difficult to achieve efficient embankment drainage and waterproofing. It is often a cyclical process of problem solving and problem solving, which is a passive processing method, resulting in a large amount of manpower, material and financial resources for post-operation maintenance
