Gate slot device suitable for different types of bulkhead gates

Abstract

The invention provides a gate slot device suitable for different types of bulkhead gates. The gate slot device is arranged in a second-phase concrete slot reserved in a diversion tunnel and used for the operation of an access door and a plugging door; the gate slot device comprises a bottom sill, a lintel, an access door main rail, a plugging door main rail, a downstream stainless water stop baseplate, a reverse rail and an upstream stainless water stop base plate, the bottom sill is arranged at the bottom of an orifice, the lintel is arranged at the top of the orifice, the access door main rail and the plugging door main rail are arranged downstream, the reverse rail is arranged upstream; when the access door blocks water, a forward supporting structure thereof acts on the access door main rail, water stopped at the gate side contacts the upstream stainless water stop base plate, and the water stopped at the bottom contacts the bottom sill; when the plugging door blocks the water, aforward supporting structure thereof acts on the plugging door main rail, the water stopped at the gate side contacts the downstream stainless water stop base plate, the water stopped at the bottom contacts the bottom sill, and the water stopped at the top contacts a water stop base plate of the lintel. According to the gate slot device suitable for different types of bulkhead gates, the access door and the plugging door share one gate slot, so that the mountain excavation size can be reduced, and the investment is saved.

Description

technical field [0001] The invention relates to the field of water conservancy and hydropower engineering, in particular to a gate slot device adapted to different types of flat gates. Background technique [0002] Large-scale high-head dam-type hydropower projects have a large flow rate, and multiple diversion tunnels with large orifices need to be installed during construction; at the same time, the construction period of the hydropower station is long, and the service life of the diversion tunnels is long. Before the dam and the flood discharge tunnel meet the discharge conditions, the diversion tunnel conducts flow diversion. After the dam and the flood discharge tunnel meet the discharge conditions, the diversion tunnel is blocked with a sealing door for the construction of a permanent plug. The dam and the flood discharge tunnel drain. During the construction of the dam, there were many flood seasons. During the flood season, the flow rate was large, and the high-spee...

Problems solved by technology

The advantage of this scheme is that it does not affect the construction period and saves the initial investment; the disadvantage is that the diversion tunnel entrance blocking door and the hoist are arranged against the mountain, and the space is small. Unless a large amount of money is invested to expand the excavation size of the mountain, two doors are arranged. groove very difficult
