Abstract

The fast closure plant includes combining piles, cross beam, steel net, positioning piles, ballast cage and block stone. After the fast closure plant is set in the dragon's mouth, the thrown block stone will be clamped by the steel net, the impact force to the block stone with be absorbed by the steel net, ballast cage, cross beam, combined piles and dam, and the water flow will be reduced. So, the block stone thrown to the downstream of the steel net will be fixed in the dam and the river will be dammed stably.

Description

Join the two sections of a bridge, etc fast device and using method thereof of dam mouth door during river cut-off

Join the two sections of a bridge, etc fast device and using method thereof of dam mouth door belongs to the hydrotechnics field during river cut-off of the present invention.

The closure of dam mouth door is the key of damming, at present to 10000m ³The above river of/second flow amount dams just very difficult, when the very moment door joins the two sections of a bridge, etc certain distance, because current are anxious especially, the concrete polyhedron of jettisoninging down, ratchel, metaling etc. are washed away by anxious current in a large number, only take tactics of human sea at last, the concrete polyhedron of the long-time very large amount of jettisoninging incessantly of employing, ratchel, metaling etc., dam is attacked and occupied forward very difficultly, until the dam closure, though the closure success has consumed great amount of manpower and material resources and financial resources.

Purpose of the present invention is exactly the problem at above appearance, and join the two sections of a bridge, etc fast device and using method thereof of dam mouth door makes the closure that can make dam mouth door fast and stable in this way when createing a kind of river cut-off.

Join the two sections of a bridge, etc fast device and using method thereof of dam mouth door during river cut-off of the present invention, mainly comprise: compound pile, crossbeam, steel mesh, guide pile, the ballast cage, stone, it is characterized in that: in advance at the good dam mouth door place of damming of prospecting, compound pile more than two groups or two groups is set in the riverbed respectively, distance between them is about 10 meters to 30 meters, be connected and fixed with it by crossbeam, guide pile is located at two groups of downstreams between the compound pile, steel mesh is connected on the ballast cage on one side, after sinking under water along guide pile, another side is connected on the crossbeam, is thrown to a large amount of stones in the ballast cage and all around with ship in the both sides upstream and downstream.Compound pile is made up of a plurality of stakes or a pier, and its top firmly connects into platform by steel work welding or concrete casting, and it highly approximates the height of the dam that dams; Crossbeam is to be made by steel structure girder or precast concrete beam, is provided with a plurality of lacing holes or suspension hook below it; Steel mesh is a rectangle, can be made into wire rope net, steel chain net or wire rope and steel chain shuffling net, the upper end of its vertical wire rope or steel chain is connected on the lacing hole or suspension hook of crossbeam, the lower end is connected on the steel structure frame of ballast cage, and the area of steel mesh mesh is between 0.5 square metre to 2.5 square metres; Pressing cage is to piece together structure by one or more cuboid steel structure frames to become, reach all around on the framework at the end and be welded into a rule crosspiece or perpendicular shelves with the steel material, the distance of shelves and shelves is between 0.2 meter to 0.4 meter, after the ballast cage sinks under water, it must be filled with the stone that ship is thrown into, and around it, form left, right, front and rear in an opposite direction.Its using method is: a mouthful door closure device is set at the good dam mouth door place of damming of prospecting in advance, when dam begins to join the two sections of a bridge, etc, assemble large-scale section heavy dump truck, bulldozer, loader, scraper, motor-driven cargo ships etc. carry out integration of operation, with the compound pile of ship at mouth door closure device, a large amount of around the ballast cage, the stone of jettisoninging in large area, make its left side, right, before, the back is firm in an opposite direction, when both sides closure dam is attacked and occupied to compound pile simultaneously, in its both sides elder generation upstream, back downstream is to the centre ratchel of jettisoninging, metaling etc., the ratchel of jettisoninging in the upstream is stuck on the steel mesh, thereafter a large amount of ratchels, metalings etc. are jettisoninged in the downstream of steel mesh, and be fixed on abutment firmly with being stuck in ratchel on the steel mesh and other building stones of upstream, stably attack and occupy forward step by step like this, join the two sections of a bridge, etc until dam.Because the effect of steel mesh, needn't worry that the stone of jettisoninging can be washed away by current, the impact force that is stuck in the stone on the steel mesh is fully absorbed decomposition by steel mesh, ballast cage, crossbeam, compound pile and dam body, the current of its back obviously weaken, the steel mesh downstream stone of jettisoninging down just can steadily be fixed on abutment like this, it is attacked and occupied forward step by step steadily, join the two sections of a bridge, etc until dam.

Join the two sections of a bridge, etc the fast advantage of device and using method thereof of dam mouth door is when adopting river cut-off of the present invention:

1, big to flow, just the time spent effect is obvious especially for river that current are anxious, rapidly and efficiently rate, safety are finished with saving time, guarantee both quality and quantity smoothly in the closure of dam mouth door when guaranteeing to dam.

2, can save a large amount of building stones, cost obviously reduces.

The dam mouth door structural profile schematic diagram of device that joins the two sections of a bridge, etc fast when accompanying drawing is river cut-off, shown in accompanying drawing: compound pile 1., crossbeam 2., guide pile 3., steel mesh 4., the ballast cage 5., stone 6..

Embodiment of the present invention are described further as follows in conjunction with the accompanying drawings:

In advance at the good dam mouth door place of damming of prospecting, in the riverbed, be provided with respectively more than two groups or two groups compound pile 1., distance between them is about 10 meters to 30 meters, 2. be connected and fixed with it by crossbeam, 3. guide pile is located at the downstream of two groups of compound piles between 1., 5. goes up Yi Bian 4. steel mesh is connected the ballast cage, after 3. sinking under water along guide pile, another side is connected crossbeam and 2. goes up, with ship the both sides upstream and downstream 6. a large amount of stones is thrown to the ballast cage 5. in and all around.Its using method is: a mouthful door closure device is set at the good dam mouth door place of damming of prospecting in advance, when dam begins to join the two sections of a bridge, etc, assemble large-scale section heavy dump truck, bulldozer, loader, scraper, motor-driven cargo ships etc. carry out integration of operation, with ship 1. at the compound pile of mouth door closure device, the ballast cage is 5. a large amount of all around, the stone of jettisoninging in large area, make its left side, right, before, the back is firm in an opposite direction, when closures dam in both sides is attacked and occupied simultaneously to compound pile 1. the time, in its both sides elder generation upstream, back downstream is to the centre ratchel of jettisoninging, metaling etc., the ratchel of jettisoninging in the upstream is stuck in steel mesh and 4. goes up, thereafter a large amount of ratchels, metalings etc. are jettisoninged in steel mesh downstream 4., and be fixed on abutment firmly with being stuck in ratchel that 4. steel mesh go up and other building stones of upstream, stably attack and occupy forward step by step like this, join the two sections of a bridge, etc until dam.
