Fabricated culvert member and construction method thereof

Abstract

The invention relates to a fabricated culvert member and a construction method thereof. The fabricated culvert member comprises a base plate, a rib plate and an arc plate, wherein the rib plate is in a gantry shape and is fixed on both ends of the arc plate, the lower ends of the arc plate and the rib plate are fixed on the base plate, the three plates are integrated, and a space between the arc plate and the base plate is a drainage channel. The fabricated culvert member provided by the invention has the advantages of factory fabrication, field assembly, simple operation, guaranteed quality,quick construction speed, simple structure, reasonable force bearing, simple maintenance (installation, removal and replacement, good integrity, high strength, large adaptive deformation, no pollution, small environmental influence, practicability, economy and obvious effect, the maintenance of the culvert member saves 20-40% human resources, material resources and money less than that of common masonry pebble revetments, town bottom or buried circular pipe culverts, and the water utilization coefficient of the canal system can be greatly increased (evaporation and seepage are reduced).

Description

technical field [0001] The invention relates to the field of small and medium-sized water conveyance buildings in farmland water conservancy projects, in particular to a prefabricated culvert component with simple structure, easy maintenance and low cost, which can increase arable land and improve canal water utilization coefficient and its implementation method. Background technique [0002] Most of the existing aqueduct systems, especially the branch, bucket, agricultural and mao canals, are earth canals, which have a large amount of evaporation and infiltration, and are prone to collapse and block channels. If the general mortar masonry pebble slope protection, town bottom or buried circular pipe culvert is used, this method consumes a lot of manpower, money and material, and it is difficult to maintain and maintain, time-consuming and difficult to construct. For example, the winter and spring repair projects in the Dujiangyan Irrigation Area require a large amount of mai...

AI Technical Summary

Problems solved by technology

[0002] Most of the existing water conveyance canal systems, especially the branch, bucket, agricultural and hair canals, are earth canals, which have large evaporation and infiltration, and are easy to collapse and block the canals. Every winter and spring, the silt must be dredged

If ordinary mortared pebble slope protection, town bottom or buried circular pipe culverts are used, this method consumes a lot of manpower, money and materials, and maintenance is difficult, time-consuming and difficult to construct.

For example, the maintenance project in winter and spring in the Dujiangyan Irrigation District requires a large amount of maintenance work, and dredging often amounts to millions of square meters; it takes a long time, 25-30 days; it is expensive, and the cost of dredging is 80-130 yuan per square meter

[0003] Most of the existing farmland water conservancy and water-saving renovation projects use concrete U-shaped grooves. Because they are open, the evaporation is very large. It can only reduce leakage, and secondly, the area above the channels cannot be effectively used.
