Abstract
The utility model relates to a hydropower station pressure regulating structure. And the utility model aims at providing a hydropower station pressure regulating structure. The hydropower station pressure regulating structure ensures that a pressure balance room achieves the requirement of the hydraulics, meanwhile stability of a surrounding rock is improved and arrangement difficulty of the pressure balance room under the condition of more hydraulic units is reduced. The technical scheme of the hydropower station pressure regulating structure is that the hydropower station pressure regulating structure comprises a diversion tunnel and the pressure balance room communicated with the tunnel. The hydropower station pressure regulating structure is characterized in that an inclined pressure balance room is arranged between a shaft line of the pressure balance room and a horizontal plane and the inclined pressure balance room presents an acute angle. The hydropower station pressure regulating structure is suitable for a water resources and hydropower project.
Description
Technical field
The utility model relates to a kind of power station pressure adjusting structure, is mainly used in the Hydraulic and Hydro-Power Engineering.
Background technology
As everyone knows, a critical function of hydraulic power plant surge-chamber is exactly service condition and the power supply quality that improves the power station, realize this function, the long-pending requirement that must satisfy holder horse neutrality section of the plane cross section of surge-chamber on hydraulics., when required surge-chamber holder horse Critical Stability section is larger, can bring following problem: the one, brought larger security risk to the adjoining rock stability of surge-chamber, especially when the geology condition was relatively poor, this problem was particularly outstanding; The 2nd, when a plurality of waterpower unit is arranged, increased surge-chamber and arranged difficulty.General surge-chamber all is vertical layout both at home and abroad at present, and the vertical shaft type surge-chamber structure is simple, and plane cross section is long-pending to be equated with vertical cross section is long-pending.
Summary of the invention
The technical problems to be solved in the utility model is: the problem for above-mentioned existence provides a kind of power station pressure adjusting structure, when guaranteeing that the surge-chamber function reaches the hydraulics requirement, improves surrounding rock stability, reduces the layout difficulty of surge-chamber under many waterpower cell cases.
The technical scheme that the utility model adopts is: the power station pressure adjusting structure, comprise diversion tunnel, and the surge-chamber that is communicated with this tunnel, it is characterized in that: the inclination surge-chamber that described surge-chamber axis is arranged horizontal by acute angle.
Described inclination surge-chamber downstream is provided with the vertical surge-chamber that is communicated with diversion tunnel equally, and described inclination surge-chamber and vertical surge-chamber top adopt the connection hole to be communicated with.
Described inclination surge-chamber can prop up the hole reconstruction by the construction with certain sloping ratio and form, and its bottom is communicated with diversion tunnel by the impedance tube connector, and the top was communicated with vertical surge-chamber by communicating pipe.
The beneficial effects of the utility model are: 1, since on the hydraulics only to the long-pending to some extent requirement of the plane cross section of surge-chamber, the inclination surge-chamber that the utility model adopts axis to arrange horizontal by acute angle replaces vertical surge-chamber of the prior art, utilize the long-pending long-pending characteristics of vertical cross section that are far longer than of inclination surge-chamber plane cross section, when satisfying the hydraulics requirement, reduced the actual excavated section area of surge-chamber, thereby improved the stability of country rock, also reduce simultaneously the layout difficulty of surge-chamber under many waterpower cell cases, thoroughly solved hydraulics in the surge-chamber design process, contradiction between adjoining rock stability and surge-chamber are arranged.2, can utilize the construction of certain sloping ratio to prop up the hole and dig, reconstruct and be the inclination surge-chamber, form the surge-chamber group with newly-built vertical surge-chamber, concur, thereby reduce the cross-sectional area of vertical surge-chamber, reduce difficulty of construction, saved engineering cost.
Description of drawings
Fig. 1 is the structural representation of embodiment 1.
Fig. 2 is the structural representation of embodiment 2.
Fig. 3 is the layout schematic diagram of embodiment 3.
Fig. 4 is that the section of embodiment 3 is arranged schematic diagram (along inclination surge shaft axis direction).
The specific embodiment
Embodiment 1: as shown in Figure 1, present embodiment comprises diversion tunnel 1, and this diversion tunnel top arranges one and is communicated with it and inclination surge-chamber 2 that self axis is arranged horizontal by acute angle.
Take cross section as circular surge shaft as example, its vertical cross section diameter is D, and the vertical cross section area is
, when it was vertically arranged, its plane cross section is long-pending to be equated with vertical cross section is long-pending, for
When it is in tilted layout (axis is horizontal by acute angle), suppose that the angle of inclination is
, then its plane cross section is long-pending is
Two kinds of arrangements are compared as can be known, when plane cross section is long-pending when equating, the excavated section when being in tilted layout long-pending when vertically arranging excavated section long-pending
Doubly, when guaranteeing that hydraulics requires, it is long-pending to have reduced excavated section, thereby has improved surrounding rock stability, has reduced the layout difficulty of surge shaft under many waterpower cell cases.
Embodiment 2: as shown in Figure 2, present embodiment comprises diversion tunnel 1, this diversion tunnel top arranges one and is communicated with it, and the inclination surge shaft 2 that axis is arranged horizontal by acute angle, this inclination surge shaft downstream (Parallel to the flow direction) is provided with the vertical surge-chamber 3 that is communicated with diversion tunnel 1 equally, described inclination surge-chamber 2 and vertical surge-chamber 3 tops are adopted connection hole 4 to be communicated with and are formed the surge-chamber group, acting in conjunction, thereby reduced the cross-sectional area of vertical surge shaft 3, avoided the relatively poor surrounding rock supporting difficulty of single large tracts of land surge-chamber large, construction sequence is complicated, problem long in time limit.
Embodiment 3: as shown in Figure 3, Figure 4, when propping up the relevant inclination tunnels such as hole when the construction with certain sloping ratio and can utilize, can reconstruct the formation surge shaft to these existing tunnels.In this example, described inclination surge-chamber 2 props up the hole reconstruction by the construction with certain sloping ratio and forms, its bottom is communicated with diversion tunnel 1 by impedance tube connector 5, the top is communicated with composition surge-chamber group by being communicated with hole 4 with vertical surge-chamber 3, acting in conjunction, it is more slow to take full advantage of a construction hole gradient, and plane cross section amasss large characteristics, effectively reduce the cross-sectional area of vertical surge-chamber 3, thereby improved surrounding rock stability; In addition, owing to utilize existing or newly-built construction is propped up the hole and reconstructed, not only save construction cost, and greatly reduced engineering quantity, accelerated construction speed.
