Abstract
The utility model belongs to the technical field of the shield constructs the machine, concretely relates to cutter head opening washing mechanism of muddy water shield constructs machine. The provided cutter head opening flushing mechanism of the slurry shield machine is provided with a main flushing pipe; the central axis of the main flushing pipe is superposed with the central axis of the cutter head; the rear end of the main flushing pipe is connected with a flushing pump welded in the center of the cutterhead in the hinged cabin; the front end of the main flushing pipe penetrates through the air cushion cabin and is positioned in the center of the cutter head; the main flushing pipe is also welded with an auxiliary flushing pipe communicated with the main flushing pipe; the auxiliary flushing pipe is connected with two groups of small flushing pipes; the two groups of small flushing pipes are positioned at the upper half part of the cutter head and are symmetrically arranged; each group of small flushing pipes is provided with a plurality of small flushing pipes, and two adjacent small flushing pipes are arranged corresponding to one opening of the cutter head. The utility model discloses reduced the number of times of opening the storehouse and clearing up the mud cake, greatly reduced working strength, improved the efficiency of construction.
Description
Technical field
The utility model belongs to shield machine technical field, and in particular to a kind of slurry shield machine cutterhead opening flushing machine.
Background technique
When carrying out slurry shield crossing construction to the stratum based on low liquid limit clay, since its soil property viscosity is larger,
Such as plasma discharge, cutterhead not in time of sizing mixing are open and are easy mud lining；Slurry shield genuine does not design cutterhead opening flushing pipeline, and shield exists
When stratum based on low liquid limit clay carries out shield-tunneling construction, 20-30 ring is promoted to need to shield according to the condition of construction at scene
Machine open a position, and to clear up mud cake primary, not only increases working strength and the security risk that opens a position, and greatly reduce construction life
Produce efficiency.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of slurry shield machine cutterhead opening washer
Structure.
The utility model is to complete above-mentioned purpose to adopt the following technical scheme that
A kind of slurry shield machine cutterhead opening flushing machine, the cutterhead flushing machine have main flush pipe；The master
The central axis of flush pipe is overlapped with the central axis of cutterhead；The rear end of the main flush pipe and the cutter head center punching in hinged cabin
Brush pump connection；The front end of the main flush pipe passes through air cushion freight space in the center of the cutterhead；It is also welded on the main flush pipe
It is connected to coupled logical auxiliary flush pipe；Two groups of small flush pipes are connected on the auxiliary flush pipe；It is small described in two groups
Flush pipe is located at the top half for excavating cabin, and small flush pipe described in two groups is symmetrical arranged；Small flush pipe described in every group is
Multiple formed punches, the two neighboring small flush pipe correspond to the opening setting of cutterhead.
The utility model proposes a kind of slurry shield machine cutterhead be open flushing machine, by adopting the above technical scheme, in mud
In water quality structure work progress, the cutterhead front openings of rotation can be rinsed using small flush pipe, utilize main flush pipe pair
Cutter head center is rinsed, and reduces the formation of cutterhead opening and center mud cake, is opened a position and is cleared up the number reduction of mud cake, drops significantly
Low working strength and security risk, improve construction production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1, main flush pipe, 2, auxiliary flush pipe, 3, small flush pipe, 4, cutterhead, 5, hinged cabin, 6, air cushion cabin, 7, punching
Brush pump.8, cabin is excavated.
Specific embodiment
The utility model is illustrated with reference to the drawings and specific embodiments:
There is master to wash away for the flushing machine as shown in Figure 1, a kind of slurry shield machine cutterhead is open, the cutterhead flushing machine
Pipe 1；The central axis of the main flush pipe 1 is overlapped with the central axis of cutterhead 4；The rear end of the main flush pipe 1 with hinged
Cutter head center washes away 7 connection of pump in cabin；The front end of the main flush pipe 1 passes through air cushion freight space in the center of the cutterhead 4；Institute
Coupled logical auxiliary flush pipe 2 is also welded on the main flush pipe 1 stated；It is connected on the auxiliary auxiliary flush pipe 2
Two groups small flush pipe 3；Small flush pipe 3 described in two groups excavates the top half in cabin 8, and small flush pipe pair described in two groups in knife
Claim setting；Small flush pipe described in every group is multiple formed punches, and the two neighboring small flush pipe corresponds to an opening of cutterhead
Setting.
In slurry shield work progress, the cutterhead front openings of rotation can be rinsed using small flush pipe, benefit
Cutter head center is rinsed with main flush pipe, reduces the formation of cutterhead opening and center mud cake, opens a position and clears up time of mud cake
Number is reduced, and is greatly reduced working strength and security risk, is improved construction production efficiency.
