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 its construction technology, comprising a prefabricated concrete bottom plate, a corrugated steel plate hole body and connecting blocks; a rail groove is arranged on the prefabricated concrete bottom plate, and the cross section of the rail groove is Inverted T-shaped and set through the two sides of the prefabricated concrete floor; the connecting blocks are fixed at the two arch feet of the corrugated steel tunnel body, and the cross-section of the connecting block is an inverted T shape suitable for the rail groove; the arch of the corrugated steel tunnel body The connection blocks connected at the feet are inserted into the rail grooves and fixed into shape. The construction technology of this culvert, in the culvert construction of complex terrain, the prefabricated concrete floor is hoisted to the predetermined position, which overcomes the defect of difficult construction on site and reduces the construction process of the cast-in-situ culvert foundation; the assembled corrugated steel plate cave body passes through the prefabricated The remaining rail grooves ensure the accuracy of assembly and facilitate hoisting; water-swellable water-stop strips and other waterproofing projects greatly improve the durability and lifespan of corrugated steel prefabricated culverts.
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 ...
