Abstract

Relating to the field of freeway construction new technologies, the invention provides a novel reconstruction and expansion structure with a side hinge limiting device. The structure consists of precast segmental plates, cast-in-situ wet joints, longitudinal ribs, PRC pipe piles, PHC pipe piles, joint end capping beams, a longitudinal cast-in-situ segment and corrugated steel guardrail stand columns. The precast segmental plates are connected by the cast-in-situ wet joints, the longitudinal ribs are disposed at the downsides of the precast segmental plates, the PHC pipe piles are arranged at the lower ends of the PRC pipe piles, the PRC pipe piles are fixedly arranged at the lower sides of the longitudinal ribs, the longitudinal cast-in-situ segment is disposed between the precast segmental plates and an original roadbed, and the corrugated steel guardrail stand columns are vertically arranged between the original roadbed and the longitudinal cast-in-situ segment. The novel reconstruction and expansion structure provided by the invention can well transfer the vertical load, also can adapt to temperature, automobile braking force and other horizontal loads, has the advantages of strong integrity, good stability, firmness and durability, and slow deformation accumulation, etc., and is conducive to high-speed driving and reduction of maintenance workload.

Description

[0001] Technical field: [0002] The invention relates to the new technology field of expressway construction, in particular to a novel reconstruction and extension structure with a side hinge limiting device. [0003] Background technique: [0004] With the development of the expressway traffic network, many original roads can no longer meet the existing needs, so many roads in China are facing the situation that they need to be widened. In the past road widening, the roadbed of the widening part is often used to fill the roadbed, and the original roadbed has settled and stable, but the filling of the widened roadbed cannot guarantee its stable settlement due to the limited construction time of filling. , It is very easy to produce cracks and the connection of new and old subgrades. In addition, the construction time of filling construction is long and the construction is complicated, which does not conform to the current leading industrial production concept. Therefore, it ...
