Description
Technical Field
The utility model relates to a portable cantilever type drought gate.
Background
The dry gate is a common gate type in the urban flood control project, is generally arranged at the crossing position of a flood bank and a traffic road, and has the main functions of blocking flood together with the flood banks at two sides in the flood season, preventing the flood from falling after the flood season and opening the gate for normal traffic in the non-flood season. With the development of urban construction, the road surface passing through the flood bank is wider and wider, and the width of the hole opening of the dry gate is also wider and wider; on the other hand, the landscape requirements on the drought gate are higher and higher, and the flood control function and the landscape requirements are met; therefore, the design difficulty of the drought gate is increased more and more.
Searching related data, and knowing that the drought gate with the largest orifice width in the flood control project in China is the drought gate of a flood control wall of a high-bridge container terminal (fourth stage) in overseas, and the largest orifice width is 25 m; the dry gate with the largest width of the orifice in province is a dry gate behind a flood bank in the downstream of the Jinjiang river in Quanzhou city, and the width of the orifice is 15 m.
The outer high bridge container terminal (stage four) has 4 container bridge approach channels, the effective width of the container bridge approach channels is 1, 25m, and 3 container bridge approach channels are 20 m. According to the flood prevention requirement, in the non-flood period, the steel gate is arranged in a side door warehouse in the flood prevention wall, and the smooth road passing in and out of the wharf is kept. When the flood is over, the steel gate is moved to a designated position through the traveling mechanism, the gap between the approach bridge and the road is sealed, and the entering of the Yangtze river tide water is blocked. And after the flood, the steel gate quickly returns to the door house to restore the smooth road. The oil cylinder on the front side of the gate pushes the gate back to the flood prevention wall, the gate is pushed back to the original position, and the traveling mechanism moves the gate back to the door warehouse. The gate door body structure is a plane steel gate of a conventional main beam frame structure, and the closing mode is as follows: the gate travelling mechanism moves the gate body to the position of the orifice, the hydraulic cylinder on the rear side of the gate pushes the gate to the backwater side of the gate slot of the gate pier against the gate slot, and water-stop rubber on the gate is compressed to form a closed water-stop surface to stop the river tide water on the outer side; the gate opening mode is that the top of a hydraulic cylinder on the front side of the gate pushes the upstream side of a gate slot of the gate pier to separate the water stop surface of the gate from the flood control wall for resetting, and the gate traveling mechanism moves the gate body to a gate warehouse to restore the smoothness of the road.
The width of a dry gate behind a Jinjiang downstream flood bank land in Quanzhou city is 15m, and the height of the dry gate is 5.84 m. According to the flood prevention requirement, the steel gate is arranged in a side door warehouse outside a flood prevention wall in the non-flood period, and the smooth road passing in and out of the urban area is kept. When flood comes, the steel gate moves to a designated position through the traveling mechanism, the bridge approach position and the gap passing through the road are sealed, and the entering of the Yangtze river tide water is blocked. And after the flood, the steel gate quickly returns to the door house to restore the smooth road. The door body structure of gate also adopts main beam frame structure, and during its mode of closing: a track is embedded above the side opening of the outer river of the dry gate, a movable double-hook electric hoist is arranged on the track, and the electric hoist lifts the gate by a small height so that the gate is not contacted with the ground; then the electric block transversely moves the gate to the dry gate orifice position, and tightens the gate and the anchor ring pre-buried on the gate pier by using the shackle, so that the water seal of the gate is compressed to form a closed water stop surface. The door opening mode is as follows: and loosening the shackle between the gate and the gate pier anchor ring, and enabling the electric hoist to transversely move the gate to the gate warehouse, taking the gate in place and fixing the gate to recover the road traffic of the gate hole.
The design of a conventional main beam frame structure is adopted, so that the rigidity of the gate body of the gate meets the standard requirement, the minimum thickness of the gate body reaches 2.35m, and the weight of the gate reaches 70 t; a2 x 400kN trolley is required to be equipped for operating the opening and closing of the gate, and the investment on a metal structure is large. Because the opening and closing of the gate are operated by the trolley, the civil engineering needs to construct a concrete opening and closing bent frame which is used for the trolley to travel and has the height of more than 5 m. An opening and closing bent frame with the height of more than 5m is built on a main traffic road, and is obviously inconsistent with the urban landscape.
Because the width-height ratio is greatly different, the gate adopts a conventional simply-supported beam force transmission structure, and the economical efficiency is poor; if a simply-supported vertical beam force transmission structure is adopted, a cross beam needs to be arranged above and below a dry gate orifice, which is obviously not suitable for the road surface of a traffic trunk road.
