Problems solved by technology
Because the cast-in-place process is generally used, although it has the advantages of firm structure and simple construction, it takes up a lot of labor during construction, the construction period is long and the requirements for the foundation are high, and it is difficult to repair after damage
However, the existing prefabricated concrete culverts generally require foundation treatment, and due to the relatively large weight of the concrete, the requirements for on-site hoisting conditions and splicing construction are high

The invention relates to the technical field of culverts, in particular to a fully-prefabricated sliding assembled culvert and a construction process thereof. The fully-prefabricated sliding assembledculvert comprises a prefabricated concrete bottom plate, a corrugated steel plate culvert body and the connecting blocks, a rail groove is formed on the prefabricated concrete bottom plate, and the cross section of the rail groove is in an inverted T shape and penetrates through the two side faces of the prefabricated concrete bottom plate. The connecting blocks are fixed to the two arch feet ofthe corrugated steel plate hole body, the cross sections of the connecting blocks are in the inverted-T shapes matched with the rail groove, and the connecting blocks connected to the arch feet of thecorrugated steel plate hole body penetrate into the rail groove and are fixedly formed. According to the culvert construction process, in the culvert construction of complex terrains, the prefabricated concrete bottom plate is hoisted to the pre-set position, the defect that the on-site construction is difficult is overcome, and the construction procedures of a cast-in-place culvert foundation are reduced; the assembled corrugated steel plate hole body penetrates through the reserved rail groove, so that the assembling precision is guaranteed, and the hoisting is facilitated; the durability and the service life of the corrugated steel plate prefabricated culvert are greatly improved through the water swelling water stop strips and other waterproof projects.
Description
technical field [0001] The invention relates to the technical field of culverts, in particular to a fully prefabricated sliding assembled culvert and a construction process thereof. Background technique [0002] As one of the important components of highway engineering, culverts and passages occupy a considerable proportion both in terms of project quantity and project cost. Since the cast-in-place process is generally used, although it has the advantages of firm structure and simple construction, it takes up a lot of labor during construction, the construction period is long and the requirements for the foundation are high, and it is difficult to repair after being damaged. However, the existing prefabricated concrete culverts generally require foundation treatment, and due to the relatively large dead weight of the concrete, the requirements for on-site hoisting conditions and splicing construction are high. [0003] In view of the above-mentioned existing defects, based ...
