Description

Technical Field

[0001] The present application relates to an assembled dam. Background Art

[0002] Reservoirs have two main functions. On the one hand, they receive water from the outside, and on the other hand, they export the stored water to the outside. When exporting water from a reservoir, it is generally done by setting up a dam. There are many problems with existing dams, such as the accumulation of debris in the reservoir, which in turn leads to a trend of eutrophication in the reservoir. In essence, the main reason for the above problems is that the existing dam structure is insufficient. Utility Model Content

[0003] In order to solve the above problems, the present application proposes an assembled dam, including a main dam body, a control gate is arranged at the upper part of the main dam body, an auxiliary dam body is arranged on the inner side of the main dam body toward the reservoir, the auxiliary dam body is provided with a lower channel relative to the middle and lower part of the reservoir, and a number of intermediate reinforcing rods are arranged between the main dam body and the auxiliary dam body; a sewage channel is arranged at the position of the main dam body corresponding to the lower channel, and a sewage gate is arranged on the inner side of the sewage channel. The present application adopts the coordinated arrangement of the main dam body and the auxiliary dam body, which strengthens the overall protection strength and reduces the direct impact of the water flow on the main dam body. Then, by setting the sewage channel, water can be discharged from the top of the main dam body while assisting the bottom pollutants to be discharged from the sewage channel.

[0004] Preferably, the main dam body includes a main dam base buried at the bottom, a main dam body with a conical shape is arranged on the main dam base, an oblique discharge edge is arranged on the upper part of the main dam body, and the control gate is arranged at the lowest point of the oblique discharge edge. The oblique discharge edge is arranged in the present application for two purposes: on the one hand, it can provide a mounting position for the control gate, and on the other hand, it can keep the discharged water away from the main dam body to avoid damage to the main dam body.

[0005] Preferably, the oblique discharge edge is arranged in a direction away from the reservoir; and the cross section of the oblique discharge edge is arc-shaped.

[0006] Preferably, the auxiliary dam body comprises an auxiliary base buried at the bottom, a columnar auxiliary body is arranged on the auxiliary base, and a top reinforcing rod is arranged on the top of the auxiliary body and is connected to the control gate.

[0007] Preferably, the control gate includes a gate frame and a lifting gate arranged in the gate frame, and the top reinforcing rod is fixedly connected to the gate frame.

[0008] Preferably, a maintenance ladder is provided between the gate frame and the main dam base.

[0009] Preferably, the sewage discharge channel is composed of a sewage discharge pipe, the sewage discharge pipe passes through the interior of the dam, and the sewage discharge gate is arranged on the sewage discharge pipe.

[0010] Preferably, the other side of the sewage channel is arranged outside the main dam body. The reason why the present application adopts the arrangement mode of extending both front and rear sides of the main dam body is that it can firstly avoid the blockage of the sewage pipe by pollutants, and secondly avoid the discharged water flow causing adverse structural effects or scouring damage to the dam body.

[0011] This application can bring the following beneficial effects:

[0012] 1. This application adopts the coordination of the main dam body and the auxiliary dam body to enhance the overall protection strength and reduce the direct impact of the water flow on the main dam body. Then, by setting up a sewage discharge channel, water can be discharged from the top of the main dam body while auxiliary bottom pollutants can be discharged from the sewage discharge channel.

[0013] 2. The inclined discharge edge of the present application has two purposes. On the one hand, it can provide an installation location for the control gate. On the other hand, it can keep the discharged water away from the main dam body to avoid damage to the main dam body.

[0014] 3. The reason why this application adopts the setting method of extending the main dam body in the front and back is that, firstly, it can avoid the blockage of the sewage pipe by pollutants, and secondly, it can avoid the discharged water flow from causing adverse structural effects or scouring damage to the dam body.
