Connecting structure and connecting method for components of prefabricated slab culvert

Abstract

The invention discloses a connecting structure and a connecting method for all components of a prefabricated slab culvert, and belongs to the technical field of road engineering. The connecting structure comprises a groove formed in the top face of the culvert foundation and used for containing the bottom of the side wall. The lower parts of the culvert side walls are distributed on the two sides of the culvert foundation, and the bottoms of the culvert side walls are located in the grooves; the culvert side wall upper parts are located at the tops of the culvert side wall lower parts; the connecting component is used for connecting the lower part of the culvert side wall with the groove and connecting the lower part of the culvert side wall with the upper part of the culvert side wall; and the top plate is in lap joint with the tops of the upper portions of the culvert side walls on the two sides. The combined slab culvert has the advantages that materials are saved, the construction cost is reduced, all parts can be industrially produced, the construction period of a culvert structure is shortened, the quality of culvert components is guaranteed, the assembly rate of all the parts is improved, the weight of all the parts is reduced, and the structural size refinement degree is high; therefore, the assembled and combined type slab culvert is the most suitable culvert form in the assembled construction of the high-fill culvert structure in the mountainous area in the future.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a connection structure and a connection method of components of a prefabricated cover culvert. Background technique [0002] During the construction of cast-in-place reinforced concrete culverts on expressways, follow-up construction can only be carried out after the concrete strength of the culvert structure reaches 75% of the design strength, causing the construction of the culvert structure to affect the construction progress of the highway project; The process of filling and compacting will also generate additional stress on the culvert structure. Since the strength of the embankment is not fully formed during the embankment filling process, cracks will occur in the culvert components. In addition, the construction quality of culvert engineering is greatly affected by seasons and rainy days, so adopting a more suitable prefabricated culvert is an urgent problem ...
