Description

[Detailed description of the invention] [Industrial application field] This invention prevents garbage and other foreign substances from being thrown into industrial waterways, drainage channels, etc., and also prevents passersby from falling into the waterways. This relates to covers for waterways, etc. installed for the purpose.

[Prior art]

Conventionally, as a cover for waterways etc.
As disclosed in Publication No. 105134, a frame body is constructed by connecting a frame-shaped main pipe and a frame-shaped reinforcing support pipe with a band-type connecting fitting,
Both ends of the main pipe in the frame are connected to the stays of a base frame fixed to the dam of the waterway, and a large number of frames are connected via connecting pipes and connecting metal fittings to form a frame. 2. Description of the Related Art A cover for a waterway or the like having a structure covered with a cover net is known.

However, in the case of a cover for a waterway or the like having this structure, the frame structure is complicated, resulting in high costs and complicated assembly work, and the frame must be manufactured to precisely match the width of the waterway. However, there is a problem in that the frame body is complicated to manufacture.

[Purpose of the invention, structure]

The purpose of this invention is to provide a cover for waterways, etc., which can advantageously solve the above-mentioned problems. The lower portions of columns 4 having a hat-shaped cross section are buried in concrete foundation members 3 installed on both sides of a waterway, etc., and the arch-shaped support frame 2 is connected at both ends of the arch-shaped support frame 2. The cover for a waterway or the like is characterized in that the upper part of the support column 4 is overlapped with the upper part of the support column 4 and connected by a fastener 5, and a cover net 6 is installed over each arch-shaped support frame 2.
