CONNECTION STRUCTURE OF DRAINAGE CHANNEL AND CONNECTION METHOD OF DRAINAGE CHANNEL

摘要

To provide a connection structure of a drainage channel, which can use a catch basin etc. that matches a size of the drainage channel when laying the drainage channel with a catchment basin etc. at a bending position of the drainage channel, and can greatly reduce installation costs of the drainage channel by facilitating a shape treatment of a tip connection part of the drainage channel.SOLUTION: A drainage channel 100 comprises: an upstream box culvert 40 that orthogonally connects an upstream drainage channel 10 through the upstream drainage channel 10 and an upstream perforated plate 30; and a downstream box culvert 70 that orthogonally connects a downstream drainage channel 20 through the downstream drainage channel 20 and a downstream perforated plate 60. A downstream end part 44 of the upstream box culvert 40 and an upstream end part 74 of the downstream box culvert 70 are each formed on a slash cut surface, and the upstream drainage channel 10 and the downstream drainage channel 20 are connected in a bent state by bringing the downstream end part 44 of the upstream box culvert 40 into contact with the upstream end part 74 of the downstream box culvert 70 to connect them.SELECTED DRAWING: Figure 1
