Cage and method for closing closure gap by combining cage with filler

Abstract

The invention relates to a cage and a method for closing a closure gap by combining the cage with filler. The technical scheme adopted in the invention is as follows: the cage is in a spatial hexahedron cage structure and is formed by connecting a spatial skeleton with a planar network structure, the cage is rectangular or is in a combined shape of rectangle and trapezoid, the skeleton is a steel structure or reinforced concrete structure, and the planar network structure is one or combination of more than one of a structural steel network, a reinforcement fabric, a steel wire mesh and a nylon mesh; and the method for closing closure by combining the cage with filler comprises the following steps of: firstly, arranging the cage on a fenced area closure river bottom protection structure; secondly, throwing and filling the filler used for river closure into the cage so as to realize the river closure on the closure gap; and thirdly, strengthening and choking inside and outside the cage so as to realize choking and closing on the closure gap. The invention has the technical effects that the cage and the method provided by the invention are used for closing a large fenced area high-flow rate closure gap by virtue of the river closure, the problem that the large fenced area high-flow rate closure gap is difficult to close by virtue of the river closure is effectively solved, the width of the closure gap is reduced, subarea dike separation is reduced or even eliminated, investment is saved, and construction period is shortened.

Description

Technical field: [0001] The invention belongs to the field of reclamation engineering, and relates to a structure for closing and closing a dragon's mouth and a method for closing and closing a dragon's mouth, in particular to a cage for closing and closing a dragon's mouth and a cage for closing and closing a dragon's mouth with fillers The closure method is used for closure and closure of high-velocity entry in large enclosures. Background technique: [0002] At present, the commonly used methods of dam closure for reclamation projects in areas along the river, coast and offshore (sea reclamation, beach reclamation, enclosure, reservoir, ash reservoir, artificial island, etc.) include the riprap prism closure method and the rappel prism closing method. The method of closing and closing the flow by bagged sand prisms is adopted. [0003] The method of closure and closure of the dragon mouth by using riprap prisms to intercept the flow: Use riprap to propel vertical plugs a...

AI Technical Summary

Problems solved by technology

Since the laying and filling of bagged sand prisms needs to be carried out at a small flow rate, this method can only be adapted to the case of a small flow rate (generally no more than 3m / s) at the faucet, and cannot adapt to the interception of a large flow rate.

[0005] For large-scale enclosures, if dikes are used to divide and close the dragon mouth to control the flow rate at the entrance, the investment in dikes will inevitably increase. If no dikes are set to reduce the investment in dikes, due to the large area of ​​the enclosure and the large amount of tidal capacity, The flow velocity of the dragon mouth is very large (often exceeding 3m / s), and the existing dragon mouth interception and closure method cannot meet the needs
