Description

Technical Field

[0001] This utility model belongs to the field of hydropower station technology, and specifically relates to a construction structure for pumping concrete into a multi-hole spillway gate pier. Background Technology

[0002] A spillway section is typically located in the middle of a hydroelectric dam for flood discharge. This spillway section has multiple gate piers, with gates installed between them to control the discharge flow. During the concrete construction of the gate piers, concrete is usually pumped into the placement area. However, due to the obstruction of the gate piers, the pump pipe for the concrete entering the placement area of ​​the middle gate pier must cross over adjacent gate piers that are under construction simultaneously. This causes mutual interference between the concrete construction work of the gate piers. The installation of the pump pipe across the gate piers is difficult, requires repeated installation and removal, resulting in high construction costs and limiting the speed of the gate pier concrete construction. Utility Model Content

[0003] The main purpose of this utility model is to provide a construction structure for pumping concrete into the dam for a multi-hole spillway gate pier, which solves the problem that the concrete pouring of the gate piers interferes with each other and affects the construction speed during the construction of the gate piers of the hydropower station dam.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a construction structure for concrete pouring and pumping into a multi-hole spillway gate pier, comprising a gate pier, the gate pier being located on the overflow section of the dam body, a reserved channel being provided at the lower end of the gate pier, a concrete pump truck being provided on the non-overflow section of the dam body, the concrete pump truck being connected to a horizontal pump pipe, the horizontal pump pipe passing through the reserved channel, a vertical pump pipe being connected to the horizontal pump pipe, and the vertical pump pipe being arranged parallel to the gate pier.

[0005] Furthermore, a horizontal walkway is also provided, which is set on the overflow surface slope between the gate piers.

[0006] Furthermore, a pad is provided at the bottom of the horizontal pump pipe.

[0007] Furthermore, a fixing clamp is connected to the vertical pump pipe.

[0008] Furthermore, the horizontal walkway is constructed using steel pipes.

[0009] Compared with the prior art, the present invention has the following beneficial effects: By setting a reserved channel at the bottom of the gate pier and by setting horizontal and vertical pump pipes, the present invention can simultaneously pour concrete for multiple gate piers, avoiding mutual interference between the concrete construction of each gate pier, accelerating the construction progress and improving construction efficiency.

[0013] See Figure 1 This utility model discloses a construction structure for pumping concrete into a multi-hole spillway gate pier, including a gate pier 1 located on the overflow section of the dam body. A reserved channel is provided at the lower end of the gate pier 1. Furthermore, the device is also equipped with a concrete pump truck 2, which is set on the non-overflow section of the dam body. The concrete pump truck 2 is connected to a horizontal pump pipe 3, which passes through the reserved channel. Furthermore, a pad 6 is provided under the horizontal pump pipe 3 to support the horizontal pump pipe 3. Furthermore, a vertical pump pipe 4 is connected to the horizontal pump pipe 3 and is arranged parallel to the gate pier 1. Furthermore, a fixing clamp 5 is connected to the vertical pump pipe 4 to fix the vertical pump pipe 4 to the outer wall of the gate pier 1, which can stabilize the vertical pump pipe 4.

[0014] Furthermore, the structure is also provided with a horizontal walkway 7, which is set on the overflow surface slope between the gate piers 1. Preferably, the horizontal walkway 7 is constructed of steel pipes, and the horizontal walkway 7 can provide a temporary operating platform for the erection of the horizontal pump pipe 3.
