Abstract
The utility model discloses the composite construction that a kind of concrete overflow dam is overlapping with power plant building, it comprises the concrete dam being arranged in upstream and the power plant building being arranged in concrete dam downstream, the dam body of described concrete dam is furnished with wasteway, diversion and power penstock is furnished with in concrete dam, after described power plant building next-door neighbour is arranged in concrete dam, described diversion and power penstock is embedded in concrete dam, and become interlaced arrangement along axis of dam direction with wasteway, structural joint is set between the interface that concrete dam contacts with power plant building or adopts integrated connection.The utility model adopts concrete overflow dam and power plant building arranged superposed, structural configuration is compact, make full use of concrete dam dam body upper space and arrange building, excavation and the concreting engineering quantity of two sides is saved compared with the multi-purpose project of dispersed placement, be conducive to centralised motorisation construction, decrease construction investment, operational management condition is better.
Description
Technical field
The utility model belongs to the dam technical field in Hydraulic and Hydro-Power Engineering, specifically relates to the composite construction that a kind of concrete overflow dam is overlapping with power plant building.
Background technology
In Hydraulic and Hydro-Power Engineering, usually barrage is needed to build a dam formation reservoir, arrange flood discharge and generating system by piloting water simultaneously, although concrete dam can arrange flood discharge at dam body, but because of the impact by topographic and geologic condition, dam, factory building, flood discharge three are set up at cloth often exists very large interference and contradiction, and especially at high-mountain gorge areas, this contradiction is quite given prominence to.For avoiding concrete dam, factory building and flood discharge are set up the problem of interference mutually at cloth, when riverbed is comparatively narrow, bank slope is steep, when discharge is larger, usually flood discharge is arranged in concrete dam dam body, and by dam and generating system by piloting water arranged apart, factory building is arranged in bank or underground, to solve dam, flood discharge, factory building three cloth is set up the contradiction of striving position, but structure needs set up longer diversion tunnel, and high-mountain gorge areas ground power house or underground power house condition often not satisfactory, thus cause the excavation of two sides and concreting engineering quantity large, invest higher, and factory, dam is arranged apart, relative distribution, operational management condition is relatively poor.
Utility model content
The purpose of this utility model is the deficiency overcome existing for prior art, provide the composite construction that a kind of concrete overflow dam is overlapping with power plant building, this structural configuration is compact, narrow river bed upper space can be made full use of and arrange building, save excavation and the concreting engineering quantity of two sides, reduce construction investment, simultaneously also for centralised motorisation construction brings convenience, building centralized arrangement, operational management condition is relatively better.
The utility model is achieved by following technical solution.
The composite construction that a kind of concrete overflow dam is overlapping with power plant building, comprise the concrete dam being arranged in upstream and the power plant building being arranged in concrete dam downstream, the dam body of described concrete dam is furnished with wasteway, diversion and power penstock is furnished with in concrete dam, after described power plant building next-door neighbour is arranged in concrete dam, described diversion and power penstock is embedded in concrete dam, and becomes interlaced arrangement along axis of dam direction with wasteway.
Structural joint is set between the interface, downstream of described concrete dam and the interface, upstream of power plant building or adopts integrated connection.
The wasteway that described concrete dam dam body is arranged is weir surface curve pattern, and end is higher than the top of power plant building.The current let out under wasteway can be made like this to cross the top of power plant building.
The upstream dam slope slope of described concrete dam is than being 1:0 ~ 1:0.3.The interface, upstream of next-door neighbour power plant building, downstream.
The fundamental profile line of described concrete dam is triangle pattern, and the slope, downstream of fundamental profile line is than being 1:0.75 ~ 1:0.85;
The top of described power plant building is closed type, and its thickness is 2m ~ 4m.Can resist certain under let out water impact.
The beneficial effects of the utility model are:
Compared with prior art, the utility model adopts concrete overflow dam and power plant building arranged superposed, structural configuration is compact, make full use of concrete dam dam body upper space and arrange building, excavation and the concreting engineering quantity of two sides is saved compared with the multi-purpose project of dispersed placement, be conducive to centralised motorisation construction, decrease construction investment, operational management condition is better.This structure economics is feasible, especially at high-mountain gorge areas, has good compliance and wide application prospect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-concrete dam, 2-wasteway, 3-diversion and power penstock, 4-power plant building.
Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1, the composite construction that a kind of concrete overflow dam described in the utility model is overlapping with power plant building, comprise the concrete dam 1 being arranged in upstream and the power plant building 4 being arranged in concrete dam 1 downstream, the dam body of described concrete dam 1 is furnished with wasteway 2, diversion and power penstock 3 is furnished with in concrete dam 1, after described power plant building 4 next-door neighbour is arranged in concrete dam 1, described diversion and power penstock 3 is embedded in concrete dam 1, and along axis of dam direction and wasteway 2 one-tenth interlaced arrangement.
Described power plant building 4 next-door neighbour arranges structural joint or adopts integrated connection after being arranged in concrete dam 1 between the interface, downstream of solidifying native dam 1 and the interface, upstream of power plant building 4; The wasteway 2 arranged at concrete dam 1 dam body adopts weir surface curve pattern, and its end, higher than the top of power plant building 4, can make the current let out for 2 times from wasteway cross the top of power plant building 4 like this.
The upstream dam slope slope of described concrete dam 1 is than being 1:0 ~ 1:0.3, the interface, upstream of next-door neighbour power plant building, downstream 2, at the top layout wasteway 2 of concrete dam 1, the fundamental profile line of concrete dam 1 is triangle pattern, and the slope, downstream of fundamental profile line is than being 1:0.75 ~ 1:0.85.
The top of described power plant building 4 is closed type, and its thickness is 2m ~ 4m, can resist certain under let out water impact.
