Abstract
The invention relates to a system for transporting and discharging silt through a hydraulic fill pipeline in front of a dam. The pipeline can transport silt with a high concentration and a small quantity of water by altitude difference operating force of a water head of the dam, and can discharge the silt of a water storage lake in a large scale. The system adopts a double-body silt dredge, wherein a gantry crane of the dredge hangs a hydraulic dredging suction end to carry out operation. The sucked hydrodynamic power drives water wheels to rotate harrowing wheels; and spike teeth of the harrowing wheels loosen hardened silt so that the silt is mixed with water flow and then becomes slurry to be transported. The foreign materials in the water flow are sheared into pieces by shears of gridholes of the harrowing wheels and a machine case. The pipeline is combined by sections, and the length of the pipeline can be changed by connections of quick connectors. The pipeline has bending flexibility because a high-strength elastic water tap structure is adopted. The pipeline discharges silt through a silt-discharging pipe orifice of a tunnel on the bottom of the dam. The tunnel on the bottom of the dam is provided with front and rear gates and a pipeline valve for safe maintenance. The system has the advantages of discharging silt in a large scale, avoiding influence of silt sediment on a dam reservoir, and saving energy along with simple equipment and convenient manufacturing, assembly, use and maintenance.
Description
Technical field
Waterpower is arranged husky system, especially system for transporting and discharging silt through hydraulic fill pipeline in front of dam before the present invention relates to a kind of dam.
Background technology
Sedimentation is the significant problem of puzzlement Dam Construction always before the dam, and it not only influences the generating in power station, also influences the capacity of reservoir before the dam, and then influences the application life of dam.Arrange husky measure at the bottom of the dam of taking at present, though alleviated the influence of sedimentation to a certain extent to the generating of dam power station, arrange husky measure at the bottom of the dam and can only take away the silt near the limited range bottom outlet but the waterpower conveying principle defines, do not have to solve substantially before the dam sedimentation the problem that influences of dam.
Summary of the invention
Sedimentation the invention provides system for transporting and discharging silt through hydraulic fill pipeline in front of dam to the problem that influences of dam before the above-mentioned dam in order to solve, and elementary solution removes before the dam sedimentation to the influence of dam.
The technical solution adopted for the present invention to solve the technical problems is: utilize the head discrepancy in elevation that forms before and after the retaining dam to be used as power, adopt the silt discharging with the retaining lake region on a large scale of hydraulic fill pipe-line transportation system.
Hydraulic fill line transportation of the present invention has the advantage that Gao Shuisha compares, sediment concentration is big and water supply volume is little.Adopt long-term uniterrupted duty, utilize the reservoir overflow water, the discharging silt of doing little by little without a break makes warehouse-in silt sediment and outbound discharging silt reach balance, makes the dam and reservoir long-term operation.
The anterior terminal of system for transporting and discharging silt through hydraulic fill pipeline of the present invention is that silt is excavated ship.
Silt is excavated ship and is adopted twin hull construction, so that improve the job stability of surface facilities, also is convenient to set up the large span straddle truck.

Slurry transportation pipeline of the present invention adopts the segmentation form, adopts pipeline snap joint to connect between pipeline section.
The length of slurry transportation pipeline realizes that by the increase and decrease of slurry pipeline hop count amount the increase and decrease of pipeline section is finished with portal jib crane.
Slurry pipeline adopts high strength elastic fire hose structure, and is crooked flexible so that the slurry transportation pipeline has under water, adapts to reservoir lakebed landform and silt and excavates moving of ship.
The rear portion terminal of system for transporting and discharging silt through hydraulic fill pipeline of the present invention is tunnel at the bottom of the dam.
The tunnel is provided with forward and backward gate at the bottom of the dam, so that the maintenance of tunnel device.
Pipeline in the tunnel is a steel, sets up by support of pipelines.
Other pipeline valve and the backup pipeline valve of all being provided with of the forward and backward gate in tunnel is so that safety inspection.
Silt is drained by terminal row sand tube mouth.
The invention has the beneficial effects as follows, adopt the hydraulic fill pipe-line transportation system on a large scale in, silt to be discharged, elementary solution except the dam before sedimentation to the influence of dam, make the dam and reservoir long-term operation; Utilize the head discrepancy in elevation that forms before and after the dam to be used as power, utilize the reservoir overflow water, the discharging silt of doing little by little without a break is saved the energy; Equipment is simple, is convenient to manufacturing, mounting, commissioning and maintenance.
