Abstract
The invention discloses the method for a kind of reservoir Diversion Tunnel backfill reconstruction flood discharging tunnel, import pylon and Diversion Tunnel stem Tunnel Section are built according to designing requirement when building and are put in place by Diversion Tunnel respectively, for the flow-guiding channel in described reservoir construction period; After reservoir building operations completes, in the maintenance gate slot of described import pylon, put into shutoff gate, the crest level of described shutoff gate equals flood discharging tunnel import floor elevation; Then according to the flood discharging tunnel requirement of design, reconstruction of diversion tunnel is flood discharging tunnel by the region fill concrete between described shutoff gate to Diversion Tunnel stem Tunnel Section.The invention has the advantages that more traditional rebuilding conduit into flood release tunnel mode, avoid secondary excavation flood discharging tunnel, reduce difficulty of construction and cost, economy and facility and shorten the duration.The inventive method is particularly useful for medium and small reservoirs flood discharging tunnel input elevation and the less situation of the inlet of diversion tunnel elevation discrepancy in elevation.
Description
Technical field
The present invention relates to the construction method of medium and small reservoirs flood discharging tunnel, especially relate to the method for reservoir Diversion Tunnel backfill reconstruction flood discharging tunnel.
Background technology
In reservoir construction process, be usually permanent flood discharging tunnel by construction period temporary building reconstruction of diversion tunnel, to reach the object reducing investment.At present in reconstruction, normally excavate Diversion Tunnel first section of tunnel (being commonly called as " dragon comes back ") and rearrange import, therefore there is certain difficulty of construction, particularly for medium and small reservoirs, permanent flood discharging tunnel input elevation and the inlet of diversion tunnel elevation discrepancy in elevation less, traditional digging mode is long in time limit, Investment Influence is comparatively large and construction technical requirement is high.
Summary of the invention
The object of the invention is to provide a kind of reservoir Diversion Tunnel to backfill the method for reconstruction flood discharging tunnel.
For achieving the above object, the present invention takes following technical proposals:
The method of reservoir Diversion Tunnel of the present invention backfill reconstruction flood discharging tunnel, import pylon and Diversion Tunnel stem Tunnel Section are built according to designing requirement when building and are put in place by Diversion Tunnel respectively, for the flow-guiding channel in described reservoir construction period; After reservoir building operations completes, in the maintenance gate slot of described import pylon, put into shutoff gate, the crest level of described shutoff gate equals flood discharging tunnel import floor elevation; Then according to the flood discharging tunnel requirement of design, reconstruction of diversion tunnel is flood discharging tunnel by the region fill concrete between described shutoff gate to Diversion Tunnel stem Tunnel Section.
The invention has the advantages that more traditional rebuilding conduit into flood release tunnel mode, avoid secondary excavation flood discharging tunnel, reduce difficulty of construction and cost, economy and facility and shorten the duration.The inventive method is particularly useful for medium and small reservoirs flood discharging tunnel input elevation and the less situation of the inlet of diversion tunnel elevation discrepancy in elevation.
Accompanying drawing explanation
Fig. 1 is the structural representation of flood discharging tunnel after the reconstruction according to the inventive method enforcement.
Detailed description of the invention
With reference to shown in Fig. 1, the method for reservoir Diversion Tunnel backfill reconstruction flood discharging tunnel of the present invention, in reservoir construction period, merges the import pylon 1 of Diversion Tunnel and flood discharging tunnel and arranges that construction puts in place, for the flow-guiding channel in described reservoir construction period; The hole that after the stem Tunnel Section 2 of described Diversion Tunnel is once excavated to and meets reconstruction, flood discharging tunnel earial drainage requires is high; After reservoir construction has been constructed, shutoff gate 4 is put in the maintenance gate slot 3 of described import pylon 1, the crest level of described shutoff gate 4 equals described flood discharging tunnel import floor elevation, reconstruction of diversion tunnel is that flood discharging tunnel can play flood discharge function by the region fill concrete then between described shutoff gate 4 to Diversion Tunnel stem Tunnel Section 2.The vertical structure shape of Diversion Tunnel stem Tunnel Section 2 fill concrete as shown in Figure 1, i.e. the planform of " dragon come back " 6.
Claims (1)
1. a method for reservoir Diversion Tunnel backfill reconstruction flood discharging tunnel, is characterized in that: in reservoir construction period, was merged by the import pylon of Diversion Tunnel and flood discharging tunnel and arranged that construction puts in place, for the flow-guiding channel in described reservoir construction period; The hole that after the stem Tunnel Section of described Diversion Tunnel is once excavated to and meets reconstruction, flood discharging tunnel earial drainage requires is high; After reservoir construction has been constructed, shutoff gate is put in the maintenance gate slot of described import pylon, the crest level of described shutoff gate equals described flood discharging tunnel import floor elevation, reconstruction of diversion tunnel is flood discharging tunnel by the region fill concrete then between described shutoff gate to Diversion Tunnel stem Tunnel Section.
