Fabricated self-drainage pipe culvert and assembling method thereof

Abstract

The invention discloses a fabricated self-draining pipe culvert and an assembling method thereof. The fabricated self-draining pipe culvert comprises a plurality of pipe culvert units, and the plurality of pipe culvert units are sequentially spliced in the axial direction to form a complete pipe culvert; each pipe culvert unit comprises a plurality of assembling pieces and a bottom plate; the plurality of assembling pieces of each pipe culvert unit include a top piece and two side pieces, and the top piece is arranged between the two side pieces; the two ends of the top piece are provided withtop piece protrusions, the upper ends of the side pieces are provided with side piece grooves, and the top piece protrusions are mounted in the side piece grooves in a fitting manner; and drainage channels are arranged between the top piece protrusions and the side piece grooves, and the drainage channels between every two adjacent pipe culvert units communicate with one another. According to thepipe culvert, the top pieces are provided with the top piece protrusions, the side piece grooves are formed in the upper ends of the side pieces, during splicing, the top piece protrusions are connected with the side piece grooves in a fitting manner, the top piece protrusions do not fit with the side piece grooves completely, the drainage channels are arranged in the splicing longitudinal seams,water seepage at the splicing longitudinal seams is gathered and discharged through the drainage channels, and the water seepage is prevented from entering the pipe culvert from the splicing longitudinal seams of the pipe culvert units.

Description

technical field [0001] The invention belongs to the technical field of culvert design, manufacture and construction, in particular to an assembled self-drainage pipe culvert and an assembly method thereof. Background technique [0002] At present, the three-piece fabricated pipe culvert has been widely used in the construction of expressways in my country due to its prefabricated components, simple construction, and less construction period; however, the traditional three-piece fabricated pipe culvert is limited by its structural form and construction method. , has disadvantages that cannot be ignored, for example: 1. All transverse joints are set on the same section, and the joints are the weak points of the structure. When the pipe culvert is subjected to a large unbalanced force in the transverse direction, Large deformation or even damage; 2. The waterproofing of the joints of pipe culverts only depends on laying waterproof materials outside the joints, and most of the wat...
