Abstract
The present invention relates to a drift-blocking closure method. It is characterized by that the closure material can be placed into multirow chain-connected float material net floated on temporary dock or at two bank sides, a traction device is used to control said closure material rowed net and make it move to front of closure mouth, the control equipment is started to remove cable and buoyancy force of material net, so that the material net can be sunk into closure mouth. Said invention can be used in water-power engineering and emergency for dam failure.
Description
The invention belongs to area of closure work technology, particularly a kind of stream method of intercepting of floating.
At present, upright stifled or flat stifled two kinds of methods commonly used are dammed in hydroelectric project both at home and abroad, wherein, vertical closure method is with the load-carrying dump truck cut-off materials such as concrete tetrahedron to be transported in an opposite direction near the dike, move backward then and travelling to clashing the dike limit on the dike in an opposite direction, cut-off material is unloaded to the river of Longkou, block the river gradually; Horizontal closure method is on trapped riverbed, sets up trestle in the Longkou in advance, successively throws completely along the Longkou with dump truck then and fills out cut-off material, or be dragged to Long Kouchu with the barge that tugboat will be loaded with cut-off material, throws and fills out cut-off material, blocks the river gradually.These two kinds of methods of damming, the former is every work of damming in the short period of time with high construction intensity on very narrow and small work plane, and has certain danger; The latter sets up pontoon bridge or trestle influence navigation on navigable river.Both all have quite a few cut-off material to be washed away by high-velocity flow, form alluvial in the downstream, for follow-up construction has increased desilting, work such as excavate, slag tap.
Purpose of the present invention is exactly the deficiency at above-mentioned situation, and a kind of employing control device that proposes is removed the buoyancy of loaded objects, makes cut-off material accurately sink to the Longkou, blocks the method in river fast.
The present invention realizes in the following manner: at trapped upper river, use transportation, load, lifting appliance 1, in the buoying device web material 2 that the many rows chain type that swims in two banks of in advance cut-off material 4 being packed into connects, the two ends hawser 5 that connects chain type buoying device web material 2 by traction thing 6 respectively, and it walks to upstream, the Longkou near zone that is not subjected to water currents to control drive, vertical direction " " word arrangement along current 8, before being displaced downwardly to Longkou 9, start-up control device 7 is removed the buoyancy of hawser 5 and buoying device 3 then, make the chain type web material of loading cut-off material dash heavy attacking and occupying with current, sink to Longkou 9, block disconnected riverbed current gradually.
The invention solves that the construction plant is little, working strength is big, hinder contradiction such as boat, can reduce simultaneously the use amount of cut-off material, the control cut-off material accurately sinks to the Longkou, avoid cut-off material by high-velocity flow wash away the desilting that forms alluvial and increase, later stage engineering quantity such as excavate, slag tap.
For big-and-middle-sized hydroelectric project, use the present invention can reduce material excavation, Transportation Engineering amount, and the desilting in the later stage of damming, engineering quantity such as excavate, slag tap, the reduction of erection time, reduce human and material resources, can be engineering simultaneously and save hundreds and thousands of ten thousand yuan investment.During flood control, burst dykes and dams crevasse incident is used the present invention can control stifled dike material and is accurately sunk to crevasse, for the quality time is won in the crevasse of quick, safe shutoff dykes and dams, thereby reduces the economic loss that flood brings.
Below in conjunction with Figure of description and embodiment the present invention is further described.
Fig. 1 is a dam project schematic diagram of the present invention.
Fig. 2 is the mansion view that chain type connects buoying device web material structure among Fig. 1.
Fig. 3 is an another embodiment of the present invention.
By illustrated in figures 1 and 2, position, 9 place is the Longkou, 8 expression water (flow) directions, 10 for clashing dike, at trapped upper river, use transportation, load, lifting appliance 1, in advance with reinforced concrete framework, boulder, cut-off materials such as concrete tetrahedron 4 are packed in the many rows chain type connection buoying device web material 2 that swims in temporary wharf or bank, the two ends hawser 5 that is connected buoying device web material 2 by two ships 6 respectively with row's chain type is connected, and upstream, the Longkou near zone that is not subjected to water currents is walked in control, direction " " word arrangement along vertical current 8, when near the certain position of Longkou 9, enable the control device 7 on the ship, as line traffic control, several different methods such as remote control or ignition is removed chain type and is connected the control hawser 5 of buoying device web material and the buoyancy of buoying device device 3, make the web material loss of buoyance that loads cut-off material, implicative of each other, dash heavy attacking and occupying with current, sink to Longkou 9, several rows of web material is blocked the river gradually.
The present invention also can be by the another kind of embodiment of realization shown in Figure 3.To narrow mountain stream, at trapped upper river, can traction control apparatus 11 be set respectively in the two sides, river, the two ends that are connected buoying device web material 2 by steel wire cable 5 with chain type are connected, and control it and travel along vertical being directed downwards of current 8, before walking to the Longkou, adopt several different methods such as line traffic control, remote control or ignition to remove the interconnect function of steel wire cable and the buoyancy of this row's buoying device web material, the web material that loading is dammed is implicative of each other dashes heavy attacking and occupying with current, sink to Longkou 9, block the river gradually.
Claims (3)
1. floating and choking river-damming method, it is characterized in that: on trapped upper river two banks, get the buoying device web material (2) that many row's chain types connect in advance ready, and cut-off material (4) is housed, the two ends hawser (5) that connects chain type buoying device web material (2) by traction thing (6) respectively, and its vertical direction along current (8) of control drive is preceding to being displaced downwardly to Longkou (9), adopt control system to remove the buoyancy of hawser (5) and buoying device (3) then, make the chain type web material dash heavy attacking and occupying with current, sink to Longkou (9) together with cut-off material.
