Abstract

The present invention is technological scheme of evacuating sediment from water reservoir, and the technological scheme includes: building one water canal around the water reservoir with sectionalizing gates and sediment flushing gate, setting gate to the reservoir and gate to the canal in the water inlet of the reservoir, evacuating the reservoir and opening the gate to the reservoir to flush out sediment through the longitudinal channel in the reservoir, excavating guide channel between the sediment flushing gate and the longitudinal channel, and opening the gate to the canal, the sediment flushing gate and the sediment draining gate to flush sediment out of the reservoir. The present invention has special sediment evacuating structure, low energy consumption, high efficiency and low cost.

Description

The reservoir desilting method
Technical field:
The present invention relates to a kind of reservoir desilting method.
Background technology:
Reservoir and natural flow station mostly all in the mountain valley or barrage build, this construction of hydropower stations investment is huge, the power station is when operation, because silt particle is constantly carried toward reservoir in the river, upstream, within a certain period of time, silt becomes silted up reservoir full, cause reservoir to be scrapped, (just consider the power station alluvial when designing, just set the power station and scrap the time limit) in the power station, particularly a lot of power stations of the Yellow River all exist this problem various countries expert to design a lot of ways, and all fail thoroughly to address this problem.
Summary of the invention:
The technical problem to be solved in the present invention provides a kind of reservoir desilting method that can effectively remove mud.Technical scheme: a kind of reservoir desilting method is characterized in that: the ring reservoir is provided with water channel (2), and segmentation lock (6) is set in the water channel, and water channel has towards become silted up mouthful (4), dashes the mouth that becomes silted up by controlling towards the silt lock; The water inlet place of reservoir is provided with warehouse-in lock (1) and distribution structure (3), and distribution structure (3) can divide into water channel (2) water; During desilting, a. is with water emptying in the reservoir; B. will put lock in storage and open, close distribution structure, mud be gone out the vertical ditch (7) that connects reservoir; C. correspondence is desired the mouth that becomes silted up that dashes of desilting zone water channel, digs out water conservancy diversion groove (8) with excavator, and water conservancy diversion groove (8) is communicated with vertical ditch (7); D. close the warehouse-in lock or adjust warehouse-in lock unlatching size to satisfy the discharge of desilting needs, close and desire desilting zone corresponding water channel segmentation lock (6), open distribution structure, towards the row of silt lock and the dam lock that becomes silted up, water sweeps away from eminence, wash away mud, discharge outside the storehouse.Beneficial effect: because the present invention has adopted distinctive dredging structure, river dashes silt via the silt mouth that dashes of water channel when dashing silt, can also come water to dash silt by the water inlet two-way through dashing become silted up mouth and reservoir, and it is few to consume energy, the efficient height, and once investment can be used for a long time.
Description of drawings:
Fig. 1 is for implementing the structural representation when of the present invention;
The schematic diagram of Fig. 2 during for desilting of the present invention;
Fig. 3 is the working state figure of the present invention towards the silt notch portion.
The specific embodiment:
As shown in Figure 1, the ring reservoir is provided with water channel 2, and the mouth 4 that becomes silted up is dashed in having of water channel, and the water inlet of reservoir is provided with warehouse-in lock 1 and distribution structure 3, and distribution structure can divide into water channel 2 water; As shown in Figure 3, dash the mouth that becomes silted up by controlling towards silt lock 5; As shown in Figure 1, be provided with segmentation lock 6 in the water channel.
Need to dash when becoming silted up, at first with water emptying in the reservoir, make only remaining mud in the reservoir, will put lock 1 in storage and open this moment, close distribution structure 3, as shown in Figure 2, mud is gone out the vertical ditch 7 that connects reservoir, desire dashing of desilting zone water channel and become silted up mouthful, dig out water conservancy diversion groove 8 for corresponding then first section with excavator, water conservancy diversion groove 8 is communicated with vertical ditch 7, then, close warehouse-in lock 1 or adjust warehouse-in lock unlatching size, close corresponding first section segmentation lock 6 of desiring desilting zone water channel to satisfy the discharge of desilting needs, open distribution structure, the row of dam 9 lock that becomes silted up, as shown in Figure 3, open towards the silt lock, water sweeps away from eminence, wash away mud 10, discharge outside the storehouse.The desilting principle in other section desilting zone is identical with aforementioned principles in the corresponding reservoir.

Claims (1)

1. reservoir desilting method is characterized in that: the ring reservoir is provided with water channel (2), and segmentation lock (6) is set in the water channel, and water channel has and dashes become silted up mouthful (4), dashes to become silted up mouthful by controlling towards the silt lock; The water inlet place of reservoir is provided with warehouse-in lock (1) and distribution structure (3), and distribution structure (3) can divide into water channel (2) water; During desilting, a. is with water emptying in the reservoir; B. will put lock in storage and open, close distribution structure, mud be gone out the vertical ditch (7) that connects reservoir; C. correspondence is desired the mouth that becomes silted up that dashes of desilting zone water channel, digs out water conservancy diversion groove (8) with excavator, and water conservancy diversion groove (8) is communicated with vertical ditch (7); D. close the warehouse-in lock or adjust warehouse-in lock unlatching size to satisfy the discharge of desilting needs, close and desire desilting zone corresponding water channel segmentation lock (6), open distribution structure, towards the row of silt lock and the dam lock that becomes silted up, water sweeps away from eminence, wash away mud, discharge outside the storehouse.
