Abstract

The invention discloses a rapid transit roadbed, which comprises sequentially arranged from bottom to top: a soft soil base, which is formed by leveling and compacting soft soil, and a drainage main pipe is pre-buried in the soft soil base; a gravel layer, which is poured with gravel and cement Formed above the soft soil base, the gravel layer is equipped with retaining walls, load-bearing frames and monitoring structures; the gravel layer is formed by pouring gravel and cement, and a water tank is installed inside the gravel layer; the permeable brick layer is brick The body is formed above the gravel layer, and the permeable brick layer is provided with a permeable structure; the asphalt concrete layer is formed above the permeable brick layer, and the asphalt concrete layer includes coarse-grained asphalt concrete below and medium-grained asphalt concrete above, and interposed between two the stiffeners between them; the pavement layer, which is formed above the asphalt concrete layer. The invention can quickly drain water, improve the safety of the rapid transit bus running in rainy days, control road surface settlement at the same time, perform effective jacking and timely response, and improve the service life of the rapid transit roadbed.

Description

technical field [0001] The invention relates to the technical field of municipal construction. More specifically, the present invention relates to a roadbed for rapid transit. Background technique [0002] Bus Rapid Transit (BRT) is more and more widely used in my country. Most of the roads dedicated to BRT in my country are asphalt pavements, which have experienced early damage to varying degrees during construction and use, which not only has a traffic impact on social traffic, but also affects the economy. caused great losses. The early damage problem of BRT special road base pavement has attracted extensive attention. SUMMARY OF THE INVENTION [0003] An object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages which will be explained later. [0004] Another object of the present invention is to provide a BRT roadbed, which can quickly drain water, improve the safety of BRT in rainy days, control the subs...
