Description

Technical Field

[0001] The utility model belongs to the technical field of highway culverts and relates to a multi-layer spliced ​​assembled box culvert structure. Background Art

[0002] Box culverts are one of the most common hydraulic structures through the dike in water conservancy projects, and have the functions of flood control, irrigation, drainage, and water storage. The existing culverts mainly include integral cast-in-place box culverts, cover culverts, pipe culverts, and prefabricated box culverts. The technical problems of wet-process cast-in-place concrete culverts in engineering are mainly reflected in: the quality of on-site pouring construction is difficult to ensure; the construction period is long, which has a great impact on the total construction period of the project; it has an adverse impact on the environment and safety; and the labor cost is high. Prefabricated box culverts have the advantages of advanced technology, low carbon and environmental protection, high construction quality, high efficiency, fast construction progress, material saving and low cost. In the field of transportation, the application of prefabrication and assembly construction technologies such as bridge beam and slab prefabrication and lining segment processing in shield construction has become more common.

[0003] However, during the construction of prefabricated culverts, the roadbed is generally not connected, and the conditions for transportation, hoisting and installation are poor, which requires high requirements for transportation, hoisting and installation. And the construction accuracy is high. Prefabricated culverts are restricted by transportation and installation, and generally need to be modularized. After modularization, the prefabricated size and accuracy requirements are high. For culverts with small and medium spans, general forms of prefabricated culverts can be used, which can well meet the relevant requirements. However, for culverts with large spans and high mass requirements, if general forms of prefabricated culverts are used, the mass and size of the components will be too large, making the production, transportation and installation of the components more difficult. In addition, due to the large mass of the components, if the method of manually controlling the installation position is still used, the safety of the construction workers cannot be guaranteed.
