Abstract

The invention provides a pillow beam type precast concrete structure layer and an assembling method thereof.The pillow beam type precast concrete structure layer comprises a plurality of precast concrete planks and a plurality of precast concrete beams; the bottoms of the precast concrete planks are provided with mounting grooves matched with the precast concrete beams in shape, and the precast concrete beams fixedly connect two or more concrete planks which are continuously laid through the mounting grooves, so that an integrated structural layer for bearing the load is formed.According to the pillow beam type precast concrete structure layer and the assembling method thereof, the precast concrete beams are arranged below the precast concrete planks, and in the assembling process, the precast concrete planks can be leveled through the precast concrete beams, so that it is guaranteed that the assembled structure layer has good flatness.

Description

technical field [0001] The invention relates to highway engineering technology and airport pavement engineering technology, in particular to a corbel-type prefabricated assembled concrete structure layer and an assembly method thereof. Background technique [0002] At present, the domestic cement concrete pavement is mainly based on on-site pouring. On-site construction will generate a large amount of waste water, waste gas, and waste residue. The construction work takes a long time, the construction machinery operates a large amount, and the degree of specialization of personnel is low. After on-site pouring, long-term maintenance is required. and other unfavorable factors. Due to the rapid economic development, it is necessary to build expressways faster, stronger and more environmentally friendly. [0003] In recent years, prefabricated structures have been widely used in the construction industry, making the construction of the construction industry more green and envir...
