Technical Field

The invention belongs to the technical field of spillway device structures, and particularly relates to a spillway device structure with an ultrahigh landslide body surge influence preventing function and the technical field of a using method.

Background

The construction of hydropower stations is often accompanied by the problem of landslide mass management, the problem of superelevation landslide mass management is a great problem, and the landslide mass is generally managed by adopting engineering measures such as arranging anti-slide piles, prestressed anchor cables, weight reduction and back pressure, retaining walls, anchor cable piles and the like. Although the engineering measures for governing the landslide body are numerous, the key of the engineering design is to select a safe, reliable, economic and reasonable measure.

At the present stage of China, large-scale hydroelectric engineering construction is mainly focused on high mountain canyon areas such as the upstream of a laneway river and the upstream of a Jinsha river, and the problem of an ultrahigh landslide body is particularly prominent. A power station at the upstream of the canjiang river relates to an ultrahigh slip mass, and the economic proportion of the design finds that the ultrahigh slip mass is treated by conventional engineering measures such as anti-slip piles, prestressed anchor cables, weight reduction and back pressure, retaining walls, anchor cable piles and the like, the cost is huge, and an ideal treatment effect is difficult to achieve. If the high-speed landslide body is driven reversely, the ultrahigh landslide body is not processed, and the hydraulic structure and the corresponding equipment can resist surge impact and reservoir water level surge caused by collapse of the high-speed landslide body after the landslide body naturally collapses. Through analysis, the scheme is lower in cost and safer in engineering compared with the conventional engineering measures.

According to the application method of the spillway device with the function of preventing the influence of the surge of the ultrahigh landslide body, the overhaul stop log gate leaves 2 and the surge prevention stop log gate leaves 4 are both in a stop log structure form, and the single-section width of the two stop log gates is determined according to the width of the gate opening; the height of the single section is generally 1.5m to 3.6m so as to meet the transportation requirement. In a normal operation state, the access stop log gate leaf 2 is stored in the door warehouse, namely not in the door slot, when the access stop log gate leaf 2 is not shown as shown in fig. 1. In a normal operation state, the anti-surge stop log gate leaf 4 is placed in the gate slot and forms a water retaining structure together with the radial gate leaf 7, and the anti-surge stop log gate leaf 4 is displayed in a state shown in fig. 1. And when the reservoir water level is normal, the water level is about 30 to 50cm lower than the top of the radial gate blade 7. When the flood season comes and the gate needs to be opened and drained, the gate leaves 4 of the anti-surge stop log gate are gradually hoisted out of the gate slots 3 in sections through the dam top opening and closing device 5 and transferred to the gate warehouse. After the anti-surge stop log gate leaves 4 are transported away completely, the radial gate leaves 7 are operated by the radial gate hydraulic hoist 8 to open the water discharge. In the maintenance state of the radial gate and the hydraulic hoist, the maintenance stop log gate leaf 2 is placed in the maintenance stop log gate slot 1 to stop water, so that the equipment maintenance is facilitated, as shown in figure 1. The surge state is caused after the occurrence of high landslide, and the surge-preventing stoplog gate leaf 4 is placed in the gate slot and forms a surge-blocking structure together with the radial gate leaf 7. The realization mode that the dam crest starting and stopping equipment 5 transports and overhauls the stop log gate door leaf 2 and prevents surging stop log gate door leaf 4 is: the dam crest hoist device 5 is a bidirectional gate hoist, the dam crest hoist device 5 can move along a dam crest track under the driving of a driving travelling mechanism, a trolley can travel on a portal, the travelling direction is vertical to the track direction of the dam crest hoist device 5, and therefore the function that one dam crest hoist device operates a plurality of sets of maintenance stop log gate vanes 2 and surge-proof stop log gate vanes 4 can be achieved. After the dam crest hoist device 5 is opened above the corresponding gate slot and is in place, the movable pulley of the trolley drives the grabbing beam to descend so as to grab a section of stop log gate, and the stop log gate is transferred after going out of the gate slot. The grabbing beam has the function of automatically grabbing and releasing the folding beam.
