Assembled wallboard and piled slab combined soilless roadbed

Abstract

The invention discloses an assembled wallboard and piled slab combined soilless roadbed and relates to the technical field of new technologies for building expressways. The assembled wallboard and piled slab combined soilless roadbed comprises prefabricated segment plates, first cast-in-situ wet joints, piled slab structure longitudinal ribs, PRC pipe piles, PHC pipe piles, connected end cover beams, wallboard structure prefabricated boards, second cast-in-situ wet joints, wallboard structure prefabricated walls, third cast-in-situ wet joints, transverse connection cast-in-situ belts and corrugated steel barrier stand columns; the piled slab structure longitudinal ribs are arranged on the lower sides of the prefabricated segment plates; the PRC pipe piles are fixedly arranged on the lower sides of the prefabricated segment plates through the connected end cover beams; the wallboard structure prefabricated boards are connected with the prefabricated segment plates through the third cast-in-situ wet joints; and the wallboard structure prefabricated boards are connected through the second cast-in-situ wet joints. The assembled wallboard and piled slab combined soilless roadbed can well transmit vertical loads, can also adapt to temperatures, car brake force and other horizontal loads, has the advantages of being high in integrity, good in stability, firm, durable, slow in deformation accumulation and the like, and facilitates high-speed driving and reduction of maintenance and repairing workloads.

Description

Technical field: [0001] The invention relates to the new technology field of expressway construction, in particular to an assembled wallboard and pile-board combined soilless roadbed. Background technique: [0002] 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 widening of highways, the roadbed of the widening part is often used to fill the roadbed, and the original roadbed has settled and stabilized, 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 the filling construction is long and the construction is complicated, which does not conform to the current leading industrial production concept. At the same time, as the traffi...
