Abstract
The utility model relates to a layered stagger type underground voltage adjustment room structure. The layered stagger type underground voltage adjustment room structure is simple in structure, safe and reliable, and therefore guarantees the adjoining rock stability in the construction period and the operating period of a large-scale hydropower station underground voltage room under poor geological conditions. According to the technical scheme, the layered stagger type underground voltage adjustment room structure is characterized by comprising a plurality of sub-voltage-adjustment-rooms, the sub-voltage-adjustment-rooms are arranged in a layered and stagger mode in the vertical direction, connecting corridors used for communicating two adjacent sub-voltage-adjustment-rooms are formed between the two adjacent sub-voltage-adjustment-rooms, and an impedance hole used for being communicated with a division tunnel is formed in the bottom of the sub-voltage-adjustment-room at the lowest end. The layered stagger type underground voltage adjustment room structure is suitable for hydropower projects.
Description
Technical field
The utility model relates to a kind of surge-chamber structure, and particularly the underground surge-chamber structure of a kind of layering alternating expression, be mainly used in Hydropower Project.
Background technology
When power station, diversion tunnel is longer, and generating diversion flow is larger, and utilized head for meeting Hydropower Plant stable operation requirement, must be arranged and generally be arranged in extensive surge-chamber in the massif country rock of below ground when relatively low.As bad as surge-chamber country rock geological conditions, the adjoining rock stability that how to guarantee extensive surge-chamber construction period and runtime is the difficult problem that must face.The long run-of-river power station that plan to build specific section on some trunk rivers of China, according to its hinge, arrange, large-scale surge-chamber (size of surge-chamber approaches or be greater than built similar engineering in the country rock good at geological conditions) must be arranged in the bad country rock of geological conditions (comprising soft rock).Now, as surge-chamber is arranged as to conventional circular cross section or gallery shape section, when the adjoining rock stability problem of the surge-chamber of this scale is unconquerable, just be related to the problem that Hydropower station pivotal is arranged or whether the power station development scheme is set up.Therefore, be necessary to study novel surge-chamber form, make in the country rock bad at geological conditions to arrange that large-scale underground surge-chamber becomes possibility.
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 simple in structure, safe and reliable underground surge-chamber structure of layering alternating expression, with the adjoining rock stability of the underground surge-chamber of Hydropower Stations in Large Scale construction period and runtime under the assurance unfavorable geological condition.
The technical scheme that the utility model adopts is: the underground surge-chamber structure of layering alternating expression, it is characterized in that: it includes some sub-surge-chambers, each sub-surge-chamber in the vertical direction layering interlaced arrangement, and be provided with the vestibule for two sub-surge-chambers are communicated with between the sub-surge-chamber of adjacent two layers; The impedance hole for being communicated with diversion tunnel is offered in the sub-surge-chamber bottom that is positioned at lowermost end.
Described sub-surge-chamber is gallery shape, and its axis is perpendicular to the axis of diversion tunnel.
Between the sub-surge-chamber of adjacent two layers, the number of vestibule is two.
The number of every straton surge-chamber is one.
Total 2-4 of described sub-surge-chamber.
The beneficial effects of the utility model are: the utility model is communicated with and forms successively by the sub-surge-chamber of some in the vertical direction layering interlaced arrangement, common high side wall surge-chamber structure is converted into to some alto sub-surge-chambers, in the situation that guarantee that surge-chamber waterpower function is constant, reduced the abutment wall height, guaranteed the stability of abutment wall country rock, broken through conventionally form surge-chamber (circle, gallery shape) restriction that scale is subject under unfavorable geological condition, guaranteed the adjoining rock stability of Hydropower Stations in Large Scale underground surge-chamber construction period and runtime under the unfavorable geological condition, some trunk rivers of China have been solved in specific section (unfavorable geological condition) upper difficult problem of arranging extensive water channeling type power station, thereby the hydropower resource of China's preciousness is fully utilized.
The accompanying drawing explanation
Fig. 1 is plan view of the present utility model.
Fig. 2 is sectional drawing of the present utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, the present embodiment comprises some sub-surge-chambers 1, each sub-surge-chamber 1 in the vertical direction layering interlaced arrangement, and every layer of the present embodiment is only arranged a sub-surge-chamber 1; The height of each straton surge-chamber 1 is determined flexibly according to actual geological conditions, the highest/minimum water level of surging of layering quantity base area matter situation, country rock situation, execution conditions, surge-chamber structure, and the height of each straton surge-chamber 1 is determined, general minute layer 2-4 layout, this example is divided into three layers of interlaced arrangement (center line that is positioned at the sub-surge-chamber of lowermost end overlaps with the center line that is positioned at the sub-surge-chamber of top); Be provided with vestibule 2 between the sub-surge-chamber 1 of adjacent two layers, for two sub-surge-chambers 1 are communicated with, make hydraulic connection necessary between each straton surge-chamber 1, guarantee whole regulating action; The impedance hole 3 for being communicated with diversion tunnel 4 is offered in sub-surge-chamber 1 bottom that is positioned at lowermost end.
In this example, described sub-surge-chamber 1 is gallery shape, and the projection of its axis on horizontal plane, perpendicular to the axis of diversion tunnel 4, arranges two vestibules 2 between the sub-surge-chamber 1 of adjacent two layers.
The present embodiment layout pattern has been broken through the restriction that conventionally form surge-chamber (circular, gallery shape) scale is subject under unfavorable geological condition, common high side wall surge-chamber (on a large scale) is converted into to several alto sub-surge-chambers 1, guarantees that the waterpower function of surge-chamber structure is constant simultaneously.
