Specific embodiment
Hereinafter, the utility model is described in detail referring to drawings and examples:
As shown in Figures 1 to 3, a kind of high pre-buried maintenance grouting device of hydraulic pressure tunnel sluicing voltage-dropping type, including connecting tube 2, institute It states connecting tube 2 to be arranged in tunnel main body 4, the profile of connecting tube 2 and tunnel main body 4 is adapted, on the outside of the connecting tube 2 and outer Side shower 1 is connected to, and 2 lower end of connecting tube is connected to connection valve 3, the outside shower 1, connecting tube 2, connection valve 3 from outside and Interior formation drainage channel, the connection valve 3, connecting tube 2,1 from-inner-to-outer of outside shower form slip casting channel.
The drainage channel can carry out sluicing decompression to lining cutting back when lining cutting behind hydraulic pressure reaches threshold value.
The slip casting channel can carry out the maintenance slip casting in later period to lining cutting, thoroughly solve that current lining cutting is difficult in maintenance to ask Topic.
The connecting tube 2 is laid along the circumferential direction of tunnel main body 4.
The laying spacing of adjacent connecting tube 2 is determined according to the actual survey situation of region of FuShui.
The outside shower 1 is located at Tunnel in tunnel main body 4, and behind, the outside shower 1 is just propped up along tunnel The circumferentially spaced-apart arrangement in outer surface.
The outside shower 1, connecting tube 2 are attached by reducing tee.
The connecting tube 2 is located in tunnel main body 4 between Tunnel, secondary lining.
The connection valve 3 is located at the inside of secondary lining in tunnel main body 4, and connection valve 3 is located at 5 top of lateral sulcus cover board.
The connection valve 3 is arranged at the above 0.5m~1.5m in 5 upper surface of lateral sulcus cover board, and the connection valve 3 is unsuitable excessively high And maintenance grouting operation space is reserved again, it is preferably provided at 1.0m.
On lateral sulcus, the lateral sulcus is connected to by drainpipe 7 with center gutter 65 buckle closure of lateral sulcus cover board.
The end of the outside shower 1 uniformly forms multiple shower holes 8 catchmented.
Circumferential spacing between two neighboring outside shower 1 is related with the practical water yield in tunnel, and the outside shower 1 it Between circumferential spacing be generally no greater than 6m.
