As shown in Figure 5, spud pile 10 is arranged in the centre bore 8 of central post 6 by bearing 11, apparatus of the present invention are arranged on the riverbed 13 in river course 12 by spud pile 10, according to riverbed situation, select the spud pile of corresponding length, first apparatus of the present invention are debugged during use, be arranged on riverbed by spud pile 11, according to its position in river, regulate the tolerance inside gas bag, apparatus of the present invention and riverbed is made to keep respective distance, near contact riverbed, blade I 2 and blade II 9 are under the impact of flow dynamic, drive apparatus of the present invention rotate, thus carry its tools 7 rotates, riverbed silt is made to be subject to breakage, riverbed, bottom plays certain for falling, and than falling further quickening water velocity, hydraulic impact becomes large, apparatus of the present invention rotating speed is accelerated thereupon, further damaged riverbed silt, under water flow velocity and apparatus of the present invention rotating speed are constantly accelerated, the riverbed degree of depth continues to deepen, the damaged area in riverbed also becomes large, the damage length of river bed water flow path direction also extends, water and silt form density current, wash away riverbed further, form riverbed, further formation curb, muddy water stream is formed again in curb, simultaneously under the effect of buoyancy tank and gas bag, apparatus of the present invention move down along spud pile, keep the distance corresponding to riverbed, riverbed silt is flushed to downstream by the current that flow velocity is accelerated, discharge from sand discharge outlet, whole section of riverbed is reduced.
During apparatus of the present invention specific works, first from the afterbody of downstream, river course, apparatus of the present invention are installed, first wash away riverbed, form curb, apparatus of the present invention work on, install another apparatus of the present invention in upstream, river course every a segment distance again, carry out work successively, each device forms the section of washing away, multiple apparatus of the present invention acting in conjunction, form relay sand surfing, many sections of washing away have been connected to a line, and silt goes out sediment ejection opening the most at last, thus riverbed, whole river course is reduced, during work, silt must have outlet, silt is discharged river course.
Below by example, embody rule of the present invention is described.
Example 1, to get certain channel 100 meters long for place, and channel is wide 0.55 meter, high 0.8 meter, sclerosis channel, at the bottom of canal, lay Yellow River Sand 0.3 meter thick, after water soaking, silt hardens, and pumping irrigation station is for water depth 0.5 meter-0.8 meter, flow velocity 0.34 meter per second, be arranged on above the silt at the bottom of canal by apparatus of the present invention by spud pile, under unhurried current impacts, blade starts helical rotation, carry its tools rotates, and silt breakage is dug down and let out.After measured, under bed load sand, let out 50 meters-70 meters, let out apart from farther under suspended load.Along with the increasing of flow velocity, it is farther that silt is washed.In this process, apparatus of the present invention move down voluntarily under the effect of buoyancy tank and gas bag, keep the distance corresponding to riverbed, during apparatus of the present invention work eleven minute, measure silt dinting depth and reach 0.15-0.18 rice, desilting area 1.5 meters is long, 0.5 meter wide, record silt dinting depth 0.2-0.25 rice after 20 minutes, desilting area 2.5 meters is long, and 0.5 meter wide.
Example 2, measure the depth of water 0.68 meter when to draw yellow lock in peach blossom valley, water flow velocity 1.1 meter per second, this device is vertical circular barreled structure, blade diameter 0.46 meter, central post is high 0.48 meter, and the cutter length of side 0.03 meter, is vertically mounted on riverbed by spud pile by this device, riverbed silt dinting depth average out to 2.0 meters is measured, decline area 1.4-1.5 rice after working 20 minutes.
Example 3, measure the depth of water 0.8 meter when to draw yellow lock in peach blossom valley, water flow velocity 1.0 meter per second, will originally be arranged on riverbed, work after one hour and measure, riverbed silt decline width is 1.4 meters, this device upstream decline length 0.7 meter, downstream decline length 0.2 meter, dinting depth average out to 0.2 meter.
Apparatus of the present invention are broken sand and are removed silt successful, and only by flow dynamic, without the need to other outside energy, time saving and energy saving, save cost, the present invention can apply in little river course, also the river that the Yellow River etc. is large can be applied to, first start working from estuary during use, silt is poured sea, carry out the work toward upstream successively, multiple apparatus of the present invention co-operation, just whole riverbed can be reduced, solve flooding, dyke breach problem, ensure people's life security, large river is convenient to open ship's navigation, promote that water resource utilizes, promote socio-economic development.
