Abstract
Provided is a grouting fixing device of a shield segment. A pre-buried steel pipe of an inner screw is arranged on a segment installed on a shield machine; another moving steel pipe is connected with the inner screw of the pre-buried steel pipe via an outer screw arranged on the other end of the moving steel pipe and stretches from the shield segment towards an enclosing palisades; a valve is installed on one end of the moving steel pipe; and a plurality of small holes are arranged in the side wall of the other end. By being fixed in advance, the segment will not swing in a filling and grouting process, so the line type of a tunnel design and effects of the grouting are easily ensured, construction is easy to control, cost is low and benefit is high.
Description
technical field:
The utility model relates to the device of the fixing shield duct piece in construction of tunnel, specifically, in a kind of tunnel adopting Mining Method or tunnel machine to construct, utilizes shield machine air pushing to install behind section of jurisdiction, location, section of jurisdiction is refilled to a kind of device of slip casting.
background technology:
At present in construction of tunnel field, running tunnel can run into the stratum section that rock and soil properties difference is very large on the way, tunnel has one section for lithostratigraphy through interval, and other section is soil layer, the way that running tunnel construction method adopts shield tunnel method, tunnel machine construction or mining method construction to combine.Adopt tunnel machine construction or mining method construction in the rock location of tunnel process, shield machine is constructed from running tunnel one end, shield machine takes way that sky pushes away segment assembly by the rock section tunnel having connected, because shield ventral brush can not sealed tube outer void, after departing from section of jurisdiction certain distance, shield machine could carry out filling and injecting slurry to pipe outer void, after slip casting process and slip casting, section of jurisdiction swings at tunnel internal, affect the linear of tunnel, and easily cause seam crossing infiltration between pipe, bring potential safety hazard to construction and the operation in tunnel.
summary of the invention:
The purpose of this utility model is to provide the slip casting fastening devices of fixing shield machine air pushing segment assembly in a kind of tunnel after Mining Method or tunnel machine method excavation.
A kind of shield duct piece slip casting fastening devices, the embedded steel tube of internal thread is set on the section of jurisdiction of installing at shield machine air pushing, the outside nut that another root movable steel pipe arranges by one end is connected with the internal thread of embedded steel tube and outside shield duct piece, extends country rock wall, this movable steel pipe one end mounted valve, other end sidewall is provided with multiple apertures.
Movable steel pipe rotates through embedded steel tube in tunnel, and one end withstands on country rock wall, and one end is stayed in tunnel and is connected with Grouting Pipe, realizes and in tunnel, fixes section of jurisdiction.
Described aperture is circular.
The utility model utilizes shield machine air pushing that section of jurisdiction is installed in the tunnel having connected, and departs from after shield tail in section of jurisdiction, by the embedded steel tube on section of jurisdiction, this shield duct piece slip casting fastening devices is installed, and then carries out the outer filling and injecting slurry of tube wall.Adopt section of jurisdiction in the utility model filling and injecting slurry process can not swing, can guarantee the effect of the linear and slip casting of Tunnel Design, construction control is simple, and cost is low.
accompanying drawing explanation:
Fig. 1 is the utility model structural representation.
Fig. 2 is the structural representation of the utility model embodiment 1.
the specific embodiment:
For further description the utility model, by following embodiment, the utility model is described in further detail, but protection domain of the present utility model is not limited to the explanation of following embodiment.
Embodiment 1:
From Fig. 1 and Fig. 2, the embedded steel tube 1 that internal thread is set on the section of jurisdiction 2 of installing at shield machine air pushing, movable steel pipe 3 one end are provided with outside nut, and embedded steel tube 1 is connected by Inside and outside screw with movable steel pipe 3, movable steel pipe 3 one end mounted valves 4, one end sidewall is provided with multiple apertures 5.Movable steel pipe 3 rotates through embedded steel tube 1 in tunnel, and one end withstands on country rock wall 7, stays one end in tunnel and is connected with Grouting Pipe by valve 4, realizes and in tunnel, fixes section of jurisdiction 2, carries out filling and injecting slurry by valve 4 to tube wall outer void 6, and 8 is country rock.Adopt this device to fix in advance section of jurisdiction, in filling and injecting slurry process, section of jurisdiction can not swing, and easily guarantees the effect of the linear and slip casting of Tunnel Design, and construction control is simple, and cost is low.
