Roadbed protection structure

Abstract

The invention discloses a roadbed protection structure, the roadbed is located between an existing railway and an existing building, the protection structure comprises a plate girder, the plate girderis laid on the roadbed, and the plate girder has an optimization effect on the stress load of the roadbed; and micro piles which are arranged below the plate girder, at least part of the micro pilesare located in the plate girder, and the micro piles provide supporting force for the plate girder. The roadbed protection structure has the advantages of being high in bearing capacity and high in stability.

Description

technical field

[0001] The present application relates to the field of geotechnical engineering, in particular to a roadbed protection structure. Background technique

[0002] Construction of subgrades in special rock and soil areas such as soft soil, expansive (rock) soil, loess, saline soil, and restricted areas adjacent to existing buildings (structures) has always been a key and difficult point in engineering construction. The problem is how to Safely handle special rock foundations while ensuring the safety and stability of existing buildings (structures).

[0003] At present, in the construction of subgrade projects in special rock and soil areas and restricted areas adjacent to existing buildings (structures), the measures often taken are to deal with special rock and soil foundations and restricted areas adjacent to existing buildings (structures), respectively. For example, the protective structure of pile-slab structure and retaining wall or anti-slide pile; the p...
