AI Technical Summary

Technical Problem

In the existing technology, after the earth shoulder is raised, it is easy to sink, become loose, have a reduced bearing capacity, and have poor connection with the original roadbed, which affects the overall structural strength and stability of the roadbed. At the same time, there is a problem of poor connection with the original block structure when installing the guardrail column.

Method used

The first hollow steel tube and the first reinforced concrete block are integrated to form a retaining structure with good continuity and integrity, and the second hollow steel tube is combined with the reinforced concrete block to achieve the standardized setting of the guardrail, and the guardrail is fixed with a bracket.

Benefits of technology

It improves the stability and durability of the earth shoulder, ensures the standardized installation of guardrails, enhances the safety of the road, and at the same time reduces the land occupation and earthwork volume, and improves the convenience of construction.

Abstract

The utility model relates to the technical field of roads and construction, in particular to a retaining framework for heightening a road shoulder and an integrated structure provided with guardrails, which comprises a plurality of first hollow steel pipes and first reinforced concrete stop dogs, two adjacent first hollow steel pipes are driven into a roadbed according to a first preset distance, and the first reinforced concrete stop dogs are driven into the roadbed according to a second preset distance. The length driven into the roadbed is greater than or equal to a first preset value; the length of the first hollow steel pipe not driven into the roadbed is greater than or equal to a second preset value; and reinforced concrete is poured on the periphery of the first hollow steel pipe and the preset position of the roadbed, so that a first reinforced concrete stop block is formed. The utility model has the advantages that: through the first hollow steel pipe and the cast-in-place first reinforced concrete stop block, the device is durable and convenient to construct. And the cast-in-place first reinforced concrete supporting stop blocks are connected with the existing roadbed into a whole through the hollow steel pipes, so that the integrity is good, and the stability and durability of the earth shoulder are improved.
