Description
Technical Field
The invention belongs to the technical field of hydraulic engineering, and particularly relates to a tunnel and gate slot connecting structure.
Background
In water conservancy project, the cross section of the tunnel is designed into a rectangular shape, a circular shape, an oval shape or other special-shaped shapes according to different conditions or conditions such as water flow, traffic, structural stress and the like, in order to control the water flow, a gate is usually arranged above the tunnel and generally consists of a door body or a door slot, the door body can slide up and down in the door slot so as to cut off or conduct the tunnel, however, the water flow flows through the tunnel in the whole time, when the gate is cut off, the water flow pressure is all acted on the door body, the door body can only transmit the acting force to the door slot, the door body can damage the door slot after a long time, the potential safety hazard of water conservancy facilities is large, on the other hand, when the door body is lifted from the water flow, if the pressure acted on the door body is too large, the friction force between the door body and the door slot is increased, and the door body needs larger lifting force when, the output power consumption of equipment needs to be improved, and the efficiency is low.
Disclosure of Invention
In order to solve the technical problem, the invention provides a tunnel and door slot connecting structure.
The invention is realized by the following technical scheme.
The invention provides a tunnel and gate slot connecting structure, wherein a tunnel is dug below the ground, a gate slot is arranged on the ground and is communicated with the tunnel, a working door is arranged in the gate slot and is in relative sliding fit connection with the gate slot, a sealing body is arranged at the connection joint of the tunnel and the gate slot, the working door and the sealing body are sequentially arranged along the flow direction of water flow in the tunnel, a water seal slot is arranged on the sealing body, the outline of the water seal slot is in a right trapezoid shape in the axial section projection of the tunnel, and the lower bottom edge of the right trapezoid faces the upstream of the water flow in the tunnel.
The thickness direction of the working door is the same as the axial direction of the tunnel.
The thickness of the sealing body is larger than that of the working door.
In the projection of the tunnel axial section, the height of the right trapezoid corresponding to the outline of the water seal groove is one third to two thirds of the thickness of the working door.
In the projection of the axial section of the tunnel, the difference between the height of the working door and the height of the tunnel is greater than the length of the upper bottom edge of the right trapezoid corresponding to the outline of the water seal tank and less than the length of the lower bottom edge of the right trapezoid corresponding to the outline of the water seal tank.
The sealing body is made of metal.
The bottom of the tunnel is embedded with a door mat, and the door mat is arranged under the working door.
The doormat top surface is flush with the tunnel bottom surface.
The door mat is formed by pouring concrete.
The invention has the beneficial effects that: by adopting the technical scheme of the invention, the sealing body is arranged at the joint of the tunnel and the door groove, the water seal groove is arranged on the sealing body, when the working door cuts off the tunnel, part of water flow can enter the water seal groove, and the upstream water flow and the water flow in the water seal groove simultaneously generate pressure on the working door, so that the friction force between the working door and the door groove is greatly reduced.
