Pressurizing water-stop efficient dismounting device and method for large-scale plane gate of vertical ship lift

Abstract

The invention discloses a pressurizing water-stop efficient dismounting device and method for a large-scale plane gate of a vertical ship lift. The efficient dismounting device comprises a gate body locking beam used for supporting and locking a plane working gate, and pressurizing and water stopping side water stopping replacement platforms used for replacing pressurizing and water stopping sidewater stopping are symmetrically installed on the two sides of the plane working gate; the bottom of the planar working gate is provided with a pressurized water-stopping bottom water-stopping replacement platform for replacing pressurized water-stopping bottom water-stopping. The device further comprises a water stop pressure plate dismounting device used for dismounting a pressurized water stoppressure plate, and a pressurizing and water stopping connecting device used for connecting pressurizing and water stopping. The dismounting device has the outstanding characteristics of simple structure, convenience and quickness in use, recyclability, capability of meeting mounting requirements, capability of solving various construction difficulties, economy, high quality, high efficiency and the like.

Description

technical field [0001] The invention relates to a device and method for high-efficiency disassembly and assembly of pressurized and water-stopped large-scale plane gates of a vertical ship lift. It is suitable for use in various types of large-scale plane gates for pressurized, water-stopped high-altitude replacement projects, and can also be used for similar structural features in other engineering fields. Provide useful reference for the replacement of various large-scale water-stop structures. Background technique [0002] The working gate of the lower sluice head of the Three Gorges ship lift is a sunken flat door with an overall size of 28.84m×19.75m×4.72m (width×height×thickness) and a weight of about 670t. A pressurized water-stop structure is arranged on the downstream surface of the gate body of the lower gate head. The water-stop device is U-shaped and consists of two water-stops. The vertical height is 19.75m, the horizontal length is 19.5m, and the water-stop wid...

Problems solved by technology

When the working time of the water-stop rubber reaches the end of its service life, or there is damage, the gate needs to be lifted out of the door slot to the locked position and then the water-stop is replaced. At this time, the gate is suspended in the air, the bottom water-stop range is completely suspended, and the side water-stop range It is suspended in the air within 10m above the ground, and it is in a high air condition during the replacement process of the water stop. At the same time, it is affected by the super large size of the pressurized water stop, the special structure and no mature replacement process for reference, the three rows of water stop pressure plates are used in conjunction, and a single piece Due to the influence of large size and weight, the replacement of the water stop faces four difficulties: difficult disassembly and assembly, difficult construction, high safety risks, and low work efficiency.
