Description
Technical field
The present invention relates to water conservancy and hydropower surge shaft field, especially a kind of water power surge shaft keeps off stone structure.
Background technique
In field of water conservancy, it is often necessary to carry out supporting to the engineering slope above surge shaft and be fallen into prevent falling stop stone
Impedance hole influences engineering safety hence into turbine-generator units.In practical projects, due to landform, the difference of geological conditions,
Different slope retaining patterns need to be taken.Support pattern such as anchor pole, anchor cable, sash beam, active and passive protection net, the gear of routine
Cob wall etc..But existing engineering slope can bring some technologies, economy and construction etc. using conventional support pattern
Problem, it is difficult to take into account the various aspects such as economy, practicability, therefore, such problems be faced, so that the side above surge shaft
It is needed when the design of its support of slope using more reasonable engineering measure.
Summary of the invention
Can effectively realize technical problem to be solved by the invention is to provide one kind prevents falling rocks from falling into impedance hole
Water power surge shaft keeps off stone structure.
The technical solution adopted by the present invention to solve the technical problems is: water power surge shaft keeps off stone structure, including is located at and adjusts
The impedance hole of bottom in kill-job, is provided with gear stone structure in the surge shaft, the gear stone structure will above impedance hole masking from
And prevent the falling rocks being originated from above surge shaft from entering in impedance hole.
Further, the gear stone structure is by surrounding the annular bottom portion enclosing of impedance hole exit setting, being uniformly arranged
Column outside annular bottom portion enclosing, and it is set to the top blind flange composition of column top.
Further, the top blind flange outer rim is provided with top flap.
Further, the top flap upwardly extends along the vertical direction.
Further, the top flap is to arrange around top blind flange outer rim one week.
Further, bar of being related is arranged between the column.
Further, being provided with concora crush hole in the top blind flange.
The beneficial effects of the present invention are: in actual use, since Falling Rocks are possible to fall into surge shaft, and falling
Enter in impedance hole, influences engineering safety hence into turbine-generator units.The present invention combines specific structural layout characteristics, ingenious
Devise gear stone structure for masking above impedance hole to prevent the falling rocks being originated from above surge shaft from entering in impedance hole, from
And the blocking realized to falling rocks effectively, inexpensive, to protect turbine-generator units.Present invention is particularly suitable for pressure regulation
In well among the protection of Falling Rocks.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
In the figure, it is marked as impedance hole 1, surge shaft 2, annular bottom portion enclosing 3, column 4, top blind flange 5, top flap 6, connection
Tie-rod 7.
Specific embodiment
The following further describes the present invention with reference to the drawings.
Water power surge shaft as shown in Figure 1 keeps off stone structure, the impedance hole 1 including being located at bottom in surge shaft 2, the pressure regulation
Gear stone structure is provided in well 2, the gear stone structure will cover to prevent from being originated from falling for 2 top of surge shaft above impedance hole 1
Stone enters in impedance hole 1.
The present invention adequately combines the positional relationship of surge shaft 2 Yu impedance hole 1, and the operation rail in view of falling rocks
Mark is cleverly provided with gear stone structure in surge shaft 2, by gear stone structure by masking above impedance hole 1 to prevent from being originated from
The falling rocks of 2 top of surge shaft enters in impedance hole 1, the thus masking realized to impedance hole 1 efficiently, economic, it is therefore prevented that
Falling rocks falls into the damage in impedance hole 1 to turbine-generator units.
In order to further improve gear stone structure to the blocking effect of falling rocks, such scheme can choose: the gear stone
Structure by the annular bottom portion enclosing 3 around the setting of 1 exit of impedance hole, the column 4 that is set on annular bottom portion enclosing 3, and
The top blind flange 5 for being set to column top is constituted.As shown in Figure 1, annular bottom portion enclosing 3 is enclosed around the outlet of impedance hole 1 one first,
It is opened to further completely cut off the falling rocks for falling into 2 bottom of surge shaft, prevents falling rocks subsequent because the forms such as rolling fall into impedance
In hole 1.Annular bottom portion enclosing 3 may be implemented to prevent ejection from directly falling to impedance hole 1 to the falling rocks of 2 inner wall of surge shaft simultaneously
Interior, top blind flange 5 then directly stops the falling rocks to fall to fall in impedance hole 1.
On the basis of above scheme, top flap 6, the top further can also be added in 5 outer rim of top blind flange
Portion's baffle 6 and top blind flange 5 can play the role of certain blocking and carry falling rocks, prevent excessive falling rocks from falling into surge shaft
2 bottoms.As shown in Figure 1, it is generally preferable to which the top flap 6 upwardly extends along the vertical direction, likewise it is preferred that the top flap
6 is around 5 outer rim of top blind flange one week arrangements.
In order to strengthen the structural support intensity of column 4, the setting connection bar 7 between the column 4 can choose, such as Fig. 1
Shown, connection bar 7 can strengthen the bearing capacity and anti-rock-fall impact ability of column 4, to make structure integrally more durable, protect
Effect is more preferable.
Due to having springing up for water flow, damage of the hydraulic pressure generated in order to prevent because springing up to gear stone structure at impedance hole 1
It is bad, it can choose the setting concora crush hole in the top blind flange 5, certainly, concora crush hole is generally comparatively fine, ventilative
Pore, thus be effectively reduced the water flow sprung up from impedance hole 1 to top blind flange 5 impact.
Design of the invention, has effectively saved project amount, has saved construction investment, and it is convenient to bring to construction, and market pushes away
Wide prospect is very wide.
