Embodiment Construction

[0019] like figure 1 , figure 2 as well as image 3 Shown is a multi-purpose tunnel layout structure combining permanent and temporary structures provided by the present invention, which can be used not only during the construction of water conservancy and hydropower projects, but also during the operation period after the construction of the project is completed. The tunnel arrangement structure includes a tunnel body 1 and a lock chamber body 3 including a bottom sill 2 arranged on the tunnel body 1. The lock chamber body 3 includes a diversion lock chamber body 4 and a water diversion chamber body arranged side by side laterally. The flood discharge sluice body 5, the elevation of the bottom sill 2 of the water diversion and flood discharge sluice body 5 is higher than the elevation of the bottom sill 2 of the diversion sluice body 4. Since the diversion sluice body 4 and the diversion and flood discharge sluice body 5 are arranged side by side in the lateral direction o...

Abstract

The invention discloses a tunnel arrangement structure, particularly discloses a multi-purpose tunnel arrangement structure, belongs to the technical field of design and construction of hydraulic and hydro-power engineering buildings and provides the permanence and temporariness combined multi-purpose tunnel arrangement structure used in the hydraulic and hydro-power engineering construction period and in the operation period after engineering construction. The multi-purpose tunnel arrangement structure comprises a tunnel body and a sill-containing lock chamber arranged on the tunnel body, wherein the lock chamber comprises a flow guide lock chamber body and a water diversion and flood discharge lock chamber body which are arranged horizontally and in parallel, and the sill elevation of the water diversion and flood discharge lock chamber body is larger than that of the flow guide lock chamber body.

Description

technical field [0001] The invention relates to a tunnel layout structure, in particular to a multi-purpose tunnel layout structure, which belongs to the technical field of water conservancy and hydropower engineering building design and construction. Background technique [0002] At present, in water conservancy and hydropower projects, during the construction of riverbed buildings, tunnels, or diversion tunnels, are needed to guide the water flow in the upstream channel to the downstream channel; when the riverbed buildings are completed, in order to meet the downstream reservoir discharge or downstream water diversion requirements It is also necessary to set up a discharge or diversion tunnel, and the previous diversion tunnel will be abandoned after the gate is closed. Therefore, in order to make full use of diversion tunnels, the combination of discharge or diversion tunnels and diversion tunnels has become the focus of research. The combination of discharge or diversi...
