Description
Technical field
The utility model relates to shield tunnel construction technology field, refers to a kind of muddy water air pressure balance shield machine diving tool changing operating system particularly.
Background technology
Tool changing operation with pressure is the Main Means solving tool wear problem in shield tunnel construction.Adopt tool changing operation with pressure, usually need the part mud in muddy water cabin to be replaced into compressed air, utilize air pressure to carry out supporting to tunnel excavation face, operating personnel is operation in compressed air, this method risk is higher, if misoperation will likely cause the accidents such as tunnel excavation face landslide.For bad geological conditions, often cannot realize the tool changing operation with pressure under compressed air supporting tunnel excavation face, then need formation to carry out reinforcing to realize normal pressure tool changing operation in this case, but this be by the time of at substantial, manpower and fund.
Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, a kind of muddy water air pressure balance shield machine diving tool changing operating system is provided, when compressed air supporting tunnel excavation face cannot be realized, tool changing job execution can be carried out without the need to carrying out stratum consolidation.
The technical solution of the utility model is: a kind of muddy water air pressure balance shield machine diving tool changing operating system, it is characterized in that: it comprises the Operating Pressure people lock be successively set in shield machine, air cushion cabin and muddy water cabin, the front portion of described Operating Pressure people lock is provided with entrance, the rear portion of described Operating Pressure people lock is provided with outlet, described Operating Pressure people lock is communicated with described air cushion cabin by outlet, described air cushion cabin is provided with UNICOM's door, and operating personnel enters described muddy water underdeck operation by described UNICOM door from described air cushion cabin; Have pressure required when operating personnel works in described Operating Pressure people lock, be full of mud in described muddy water cabin, the mud level in described air cushion cabin is positioned on described UNICOM door.
2, a kind of muddy water air pressure balance shield machine diving tool changing operating system according to claim 1, is characterized in that: described outlet is arranged at above described UNICOM door.
The utility model, without the need to the part mud in shield structure muddy water cabin is replaced into compressed air, reduces the risk that operating personnel's operation in compressed air brings when tool changing operation; Simultaneously without the need to carrying out the stratum consolidation of time and effort consuming to realize carrying out tool changing operation at ambient pressure, the muddy water air pressure balance shield structure tool changing operation under any geological conditions can be realized.
The utility model has the economy of good operability, security reliability and use, has very high promotional value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to figure 1, a kind of muddy water air pressure balance shield machine diving tool changing operating system of the present embodiment, it comprises the Operating Pressure people lock 3 be successively set in shield machine, air cushion cabin 2 and muddy water cabin 1, the front portion of Operating Pressure people lock 3 is provided with entrance 3.1, the rear portion of Operating Pressure people lock 3 is provided with outlet 3.2, Operating Pressure people lock 3 is communicated with air cushion cabin 2 by outlet 3.2, air cushion cabin 2 be provided with UNICOM's door 4, operating personnel enters operation in muddy water cabin 1 by UNICOM's door 4 from air cushion cabin 2; Have pressure required when operating personnel works in Operating Pressure people lock 3, be full of mud in muddy water cabin 1, the mud level in air cushion cabin 2 is positioned on UNICOM's door 4.
The specific implementation method of the present embodiment is:
A, balance muddy water cabin 1 and pressure in air cushion cabin 2, mud level in air cushion cabin 2 is made to exceed UNICOM's door 4 between muddy water cabin 1 and air cushion cabin 2, if mud level is lower than UNICOM's door 4 in air cushion cabin 2, after opening UNICOM's door 4, the mud in muddy water cabin 2 can be revealed and cause pressure drop in cabin, mud in muddy water cabin 2 is supporting tunnel excavation face, by mud level in air cushion cabin 2 higher than UNICOM's door 4, make muddy water cabin 1 be in equilibrium state with the pressure in air cushion cabin 2, mud in muddy water cabin 1 can not be caused after opening UNICOM's door 4 to reveal build-up of pressure and decline;
B, operating personnel enter pressurization in Operating Pressure people lock 3 after putting on diving equipment, until pressure and air cushion cabin 2 pressure balance in Operating Pressure people lock 3;
C, operating personnel enter in air cushion cabin 2 and start diving, and after opening UNICOM's door 4 in air cushion cabin 2 and muddy water cabin 1, operating personnel enters diving in muddy water cabin 1, carries out tool changing operation;
After in d, muddy water cabin 1, one-stop operation terminates, the decompression program different according to the different choice of selected diving techniques: according to compressed-air diving technology, operating personnel enters in Operating Pressure people lock 3 and reduces pressure after the end of job; According to saturation diving technology, operating personnel will return in accommodation and continue hyperbaric environment life until reduce pressure after whole end of job.
Outlet 3.2 in the present embodiment need arrange with UNICOM door 4 above.
Compared with traditional muddy water air pressure balance shield structure tool changing operational method, the utility model, without the need to the part mud in shield structure muddy water cabin 1 is replaced into compressed air, reduces the risk that operating personnel's operation in compressed air brings when tool changing operation; Simultaneously without the need to carrying out the stratum consolidation of time and effort consuming to realize carrying out tool changing operation at ambient pressure, the muddy water air pressure balance shield structure tool changing operation under any geological conditions can be realized.
The present embodiment has the economy of good operability, security reliability and use, has very high promotional value.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
