Abstract
(B, ) the utility model discloses a structure that diversion tunnel and flood discharge hole combine is including diversion tunnel (1) and flood discharge hole (2), the diversion tunnel entrance point is equipped with diversion tunnel import lock chamber (3), the flood discharge hole is connected with the diversion tunnel, and the entrance point in flood discharge hole is equipped with flood discharge import floodgate (5), is equipped with flood discharge export floodgate (6) on the flood discharge hole of flood discharge hole and diversion tunnel junction, be equipped with in the diversion tunnel of flood discharge hole and diversion tunnel junction shutoff section (4). The utility model provides a diversion tunnel and flood discharge hole separately arrange the problem that has increased construction work volume, construction period and construction investment, arrange through combining, reduced the construction investment, effectual satisfied construction diversion require with permanent flood discharge requirement, compare the tradition method of arranging and has reduced the construction work volume, shortened construction period. (B, )
Description
Technical field
The utility model relates to the structure of a kind of Diversion Tunnel and flood discharging tunnel combination, belongs to the hydraulic architecture technical field in Hydraulic and Hydro-Power Engineering.
Background technology
In Process of Hydropower Plant Construction, most of engineering all can relate to should arrange that Diversion Tunnel arranges the situation of flood discharging tunnel again, conventional way normally arranges separately a Diversion Tunnel and a flood discharging tunnel, both are independent of each other, although conventional way can meet the needs of engineering, investment is comparatively large, difficulty of construction is high, the construction period is long.Therefore, need to find a kind of most economical arrangement and both can meet requirement of engineering, can construction costs be reduced again.
Utility model content
The purpose of this utility model is, provides the structure that a kind of Diversion Tunnel and flood discharging tunnel combine, and to solve the technical problem that prior art investment is comparatively large, difficulty of construction is high, the construction period is long, thus overcomes the deficiencies in the prior art.
The technical solution of the utility model is achieved in that
The structure that a kind of Diversion Tunnel of the present utility model and flood discharging tunnel combine is that this structure comprises Diversion Tunnel and flood discharging tunnel; Inlet of diversion tunnel end is provided with inlet of diversion tunnel lock chamber; Flood discharging tunnel is connected with Diversion Tunnel, and the entrance point of flood discharging tunnel is provided with flood discharge import lock, and the flood discharging tunnel of flood discharging tunnel and Diversion Tunnel junction is provided with flood discharge and exports lock; Block section is provided with in the Diversion Tunnel of flood discharging tunnel and Diversion Tunnel junction.
In aforementioned structure, the cross section of described Diversion Tunnel is rectangle, and its top is arch.
In aforementioned structure, the cross section of described flood discharging tunnel is tubular.
Owing to have employed technique scheme, the utility model compared with prior art, the utility model solves Diversion Tunnel and the flood discharging tunnel problem adding construction works amount, construction period and construction investment arranged apart, arrange by combining, reduce construction investment, effectively meet construction diversion requirement and permanent flood discharge requirement, compare traditional arrangement method and decrease construction works amount, shorten the construction period.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, but not as to any restriction of the present utility model.
The utility model is that constructed by the construction method that combines according to following a kind of Diversion Tunnel and flood discharging tunnel, as shown in figures 1-4, the method first carries out the construction of Diversion Tunnel 1, is provided with inlet of diversion tunnel lock chamber 3 at the entrance point of Diversion Tunnel; After Diversion Tunnel starts water conservancy diversion, then carry out the construction of flood discharging tunnel 2; The entrance point of flood discharging tunnel is provided with flood discharge import lock 5, and the port of export of flood discharging tunnel is connected with Diversion Tunnel; Flood discharge outlet lock 6 is provided with at the port of export of flood discharging tunnel; By Diversion Tunnel and the shutoff of flood discharging tunnel junction after flood discharging tunnel is fixed, after block section 4 consolidation of Diversion Tunnel, open flood discharge outlet lock and flood discharge import lock, carry out flood discharge by flood discharging tunnel and discharge water.
The structure that the of the present utility model a kind of Diversion Tunnel formed according to said method and flood discharging tunnel combine, as shown in figures 1-4, this structure comprises Diversion Tunnel 1 and flood discharging tunnel 2; The cross section of Diversion Tunnel is rectangle, and its top is arch.Inlet of diversion tunnel end is provided with inlet of diversion tunnel lock chamber 3; Flood discharging tunnel is connected with Diversion Tunnel, and the entrance point of flood discharging tunnel is provided with flood discharge import lock 5.The cross section of flood discharging tunnel 2 is tubular.The flood discharging tunnel of flood discharging tunnel and Diversion Tunnel junction is provided with flood discharge and exports lock 6; Block section 4 is provided with in the Diversion Tunnel of flood discharging tunnel and Diversion Tunnel junction.
Embodiment
During concrete enforcement, implement in accordance with the following steps:
Step 1, first carry out Diversion Tunnel 1 and flood discharging tunnel 2 excavates and first liner timbering, after excavating and first liner timbering completes, carry out reinforced concrete lining layer construction.
Step 2, having constructed and meet after design strength requires until Diversion Tunnel 1 and flood discharging tunnel 2 reinforced concrete lining layer, close flood discharge import lock 5 and flood discharge outlet lock 6, Diversion Tunnel starts overcurrent.
Step 3, until major project is complete build after, inlet of diversion tunnel lock chamber 3 times locks, starting to build block section 4, has constructed and has met after design strength requires in block section, can determine whether to open flood discharge import lock 5 according to requirement of engineering and flood discharge outlet lock 6 flood discharging tunnel barrel lock chamber carries out releasing flood.
