Waterdoor Introduction
In the underground may be threatened by the damage location, to prevent a sudden influx of groundwater and
other roadway cross-section specifically set water gate.
Water-proof Floodgate Door Operation
Waterproof gate (waterdoor) is set up in order to prevent underground water suddenly a mine water facilities,
with the door are usually made of concrete wall battlements, door frames and can open doors.
The shape of the door leaf, which has two kinds of circular and rectangular.
When the water pressure more than 3 mpa, available spherical shape door leaf against huge water pressure.
Door plank is generally made from iron or steel plate, and its thickness according to the size of the water pressure.
When the water pressure is less than 4 mpa, 36 a 65 mm steel plate are available,
or a certain thickness of steel plate on both sides isteel welding;
When the water pressure more than 4 mpa, should use the iron casting.
Door frame dimensions should meet the transport requirements of the general width of 0.9 to lm, height of 1.8 ~2 m. Doors and door frames made oblique contact surface, during which the rubber mat board, stereotype or tar-impregnated canvas, ensuring tight contact surface watertight.
Waterdoor Application
Waterdoor installed in the water need to block the flow of water and usually need transportation,
pedestrian tunnel, for example, the total confluence to flood threat area of roadway and bottom,
underground water pump room, etc. Setting the waterproof gate of surrounding rock should be solid,
impervious.Within the concrete wall battlements round to wedge rock, with water under high pressure and no leaking.
Waterproof gate is open at ordinary times, install it where a short activity of rail,
the water inrush occurs could quickly dismantled activity rail, the waterproof gate is closed.
Gate close should be origin water side of the lateral direction.
