Four slot openings are provided on the adjacent sides of the middle pier and the side piers. The slot openings are filled with secondary concrete to form a storage gate slot and a working gate slot. The trash rack maintenance platform is arranged on the upper side surfaces of the middle pier and the side piers. The gate machine track is located on the outer sides of the storage gate slot and the working gate slot and is arranged on the trash rack maintenance platform. The bottom of the gate machine is movably arranged in the gate machine track, and the gate machine is arranged above the trash rack maintenance platform.

[0007] Further, there are multiple middle piers. Four slot openings are provided on the adjacent sides of adjacent middle piers. The slot openings are filled with secondary concrete to form a storage gate slot and a working gate slot.

[0008] Further, the storage gate slot and the working gate slot are connected in series in the trash rack maintenance platform in the direction perpendicular to the water flow.

[0009] Further, the gate slot crossbeam at the bottom of the working gate slot is arranged on the trash rack bottom plate.

[0010] Further, the bottom beam of the storage gate slot and the gate slot crossbeam are arranged on the trash rack top plate.

[0011] Further, the storage gate slot and the working gate slot are arranged in parallel.

[0012] A trash rack and gate co-slot structure provided by the present utility model: not only can it enable maintenance conditions for the entire section of the water conveyance channel, but also effectively optimize the problem of the independent operation of the double platforms of the gate and the trash rack in the existing structure of the pumped storage inlet / outlet. In the direction perpendicular to the water flow, the trash rack maintenance platform connects the working gate slot and the storage gate slot in series, optimizes the structure of the gate well and its platform, can significantly reduce the project investment, optimize the construction period, and has high reliability and practicability.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The present utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0019] The co-slot structure is based on the trash rack maintenance platform, connects the working gate slot and the storage gate slot in series, and has a structure where the gate and the trash rack share a working gate slot, which is applicable to the design projects of hydropower and water conservancy structures.

[0020] Refer to the attached Figures 1-4 , a trash rack and gate co-slot structure, including a middle pier 6, a side pier 7, a gate machine 5 and a gate machine track 4. Four slots are opened on the adjacent sides of the middle pier 6 and the side pier 7. The slots are filled with secondary concrete 10 to form a storage gate slot 1 and a working gate slot 2. The trash rack maintenance platform 3 is arranged on the upper side surfaces of the middle pier 6 and the side pier 7. The gate machine track 4 is located on the outer sides of the storage gate slot 1 and the working gate slot 2 and is arranged on the trash rack maintenance platform 3. The bottom of the gate machine 5 is movably arranged in the gate machine track 4, and the gate machine 5 is arranged above the trash rack maintenance platform 3.

[0021] There are multiple middle piers 6, and four slots are opened on the adjacent sides of adjacent middle piers 6. The slots are filled with secondary concrete 10 to form a storage gate slot 1 and a working gate slot 2.
