TECHNICAL FIELD
[0001] The present application relates to a kind of underwater intake trash rack structure and its construction method.It is suitable for construction technical field. BACKGROUND
[0002] At present, in river and reservoir channel, it is necessary to set up trash rack to filter larger impurities in water flow, to avoid blockage. The conventional intake trash rack arrangement is to set trash rack slot on both sides of the channel, and the trash rack is hoisted by opening and closing equipment and clamped in the trash rack slot. For the intake structure of taking water in the reservoir, the intake is arranged underwater, and it is not convenient to set trash rack slot at the intake, so it is not convenient to insert the trash rack at the intake. Due to the short emptying time of the reservoir or the inability to empty, some trash racks do not have dry land installation conditions, so underwater trash rack installation operation is required, which is very difficult to construct. SUMMARY
[0003] The technical problem to be solved by the present application is: to solve the above technical problems, the present application provides a kind of underwater intake trash rack structure and its construction method.

Personnel can enter the water inlet through the outlet end of the water conveying pipe to construct the trash rack body, and the trash rack body is installed on dry land.
[0022] The beneficial effects of the present application are as follows: the first concrete structure is constructed when the water level in the reservoir is in the low water level period, the water inlet is reserved, and the baffle is installed at the corresponding position of the water inlet on the first concrete structure. When the water level in the reservoir rises, the water flow does not flow into the water inlet, and the construction of the water conveying pipe and the trash rack body in the water inlet is not affected. The second anchor bar is pre-buried at the positions on both sides of the water inlet during the construction of the first concrete structure. When the baffle blocks the water inlet, personnel can enter the water inlet through the water outlet of the water conveying pipe to construct the second concrete structure. When the second concrete structure is constructed, the first anchor bar on the mounting plate is buried in the second concrete structure, and the mounting plate is fixedly installed at the water inlet.
