Abstract
The invention relates to a long water diversion tunnel stone collecting pit structure, in particular to the long water diversion tunnel stone collecting pit structure applied to the technical field of water resource and hydroelectric engineering. The long water diversion tunnel stone collecting pit structure effectively prevents block stone accumulated in stone collecting pits from being taken away by water flow to damage water resource and hydroelectric equipment. The long water diversion tunnel stone collecting pit structure comprises pit bodies arranged separately, and grille bars are arranged inside the pit bodies. The long water diversion tunnel stone collecting pit structure further comprises tooth grooves, the tooth grooves are fixed inside the pit bodies, and the two ends of each grille bar are placed in the corresponding tooth grooves. The grille bars arranged inside the pit bodies are used for preventing the block stone in the stone collecting pits from being taken away by the water flow. When the block stone in the stone collecting pits generates a trend to flow away in the water flow direction under the function of the water flow, the grille bars arranged inside the pit bodies generate corresponding resistance to the block stone, under the resistance function of the grille bars, the block stone can not be taken away by the water flow, and in this way, the block stone can be effectively avoided flowing away with the water flow to enter a water turbine after passing through a pressure balance chamber and a pressure pipeline to damage the water turbine.
Description
Technical field
The present invention relates to a kind of the long diversion tunnel collection stone pit structure, particularly a kind of the long diversion tunnel collection stone pit structure being applied to Hydraulic and Hydro-Power Engineering technical field.
Background technology
In Hydraulic and Hydro-Power Engineering, run because the long diversion tunnel mostly is the mode that shotcrete bolt lining is combined with concrete lining, quote flow large, diversion tunnel is long, be inconvenient to overhaul, a lot of spray-up concrete block and stone is had to drop in diversion tunnel in shotcrete bolt lining section, for the security of operation in power station is considered, according to diversion tunnel length, one or more snippets collection stone pit is set, collection stone pit is arranged along water (flow) direction usually, each section of collection stone pit is divided into a few railway carriage or compartment to separate setting, collect diversion tunnel drives walking along the line block stone through current, block stone falls into collection stone pit and piles up, block stone in stone pit will be collected remove when power station is overhauled.In the prior art, often pile up some block stones inside the collection stone pit that the long diversion tunnel is arranged, wherein some block stone will be taken away with current, and through surge-chamber, pressure pipeline enters the hydraulic turbine, produce destroy the hydraulic turbine.Therefore also do not have a kind of block stone piled up in collection stone pit that can effectively prevent to be taken away by current in prior art, and then destroy the long diversion tunnel collection stone pit structure of the hydraulic turbine.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of block stone piled up in collection stone pit that can effectively prevent and is taken away by current, and then destroys the long diversion tunnel collection stone pit structure of water conservancy and hydropower equipment.
For solving the problems of the technologies described above, the long diversion tunnel collection stone pit structure that the present invention adopts, comprise the hole body separated and arrange, the inside of described hole body is provided with grille strip.
Further, also comprise teeth groove, it is inner that described teeth groove is fixed on hole body, and the two ends of described grille strip are placed in teeth groove.
Further, the surrounding of described teeth groove is provided with muscle pawl, and described muscle pawl is imbedded in the body of hole.
Further, the two ends of described grille strip are provided with hanger.
Further, the mid portion of described grille strip is strip, and the scope of the included angle A of its normal orientation and horizontal direction is 10 ° of <A<80 °.
Further, the scope of the described normal orientation of grille strip mid portion and the included angle A of horizontal direction is 43 ° of <A<47 °.
Further, concora crush hole is also provided with between described adjacent pits body.
The invention has the beneficial effects as follows: the grille strip that the inside of hole body is arranged is used for preventing the block stone collected in stone pit from being taken away by current.Produce in the trend that water (flow) direction flows away under collecting the effect of the block stone in stone pit at current, the grille strip being arranged on body inside, hole produces corresponding resistance to block stone, under the drag effect of grille strip, block stone can not be taken away by current, so just can effectively avoid block stone with current, through surge-chamber, pressure pipeline enters the hydraulic turbine, produces destroy the hydraulic turbine.It is inner that teeth groove is used for grille strip being fixed on hole body.The surrounding of teeth groove is provided with muscle pawl, is imbedded by muscle pawl in the body of hole, reliably can fix like this to teeth groove during construction.The two ends of grille strip are provided with installation and replacing that hanger can facilitate grille strip.The mid portion of the strip of grille strip, from the horizontal by certain angle slant setting, better can play barrier effect to block stone.The concora crush hole arranged between adjacent pits body is used for balancing water pressure the ponding of discharging in time in the body of hole.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, Figure 2 and Figure 3, the long diversion tunnel collection stone pit structure of the present invention, comprise spaced hole body 1, the inside of described hole body 1 is provided with grille strip 2.The grille strip 2 that the inside of hole body 1 is arranged is used for preventing the block stone collected in stone pit from being taken away by current.Produce in the trend that water (flow) direction flows away under collecting the effect of the block stone in stone pit at current, the grille strip 2 being arranged on body 1 inside, hole produces corresponding resistance to block stone, under the drag effect of grille strip 2, block stone can not be taken away by current, so just can effectively avoid block stone with current, through surge-chamber, pressure pipeline enters the hydraulic turbine, produces destroy the hydraulic turbine.
Also comprise teeth groove 3, it is inner that described teeth groove 3 is fixed on hole body 1, and the two ends of described grille strip 2 are placed in teeth groove 3.It is inner that teeth groove 3 is used for grille strip 2 being fixed on hole body 1.
The surrounding of described teeth groove 3 is provided with muscle pawl 4, and described muscle pawl 4 is imbedded in the body 1 of hole.The surrounding of teeth groove 3 is provided with muscle pawl 4, is imbedded by muscle pawl 4 in the body 1 of hole, reliably can fix like this to teeth groove 3 during construction.
