Description
Technical field
The utility model belongs to the technical field of constructing metro tunnel, is specially one and is applicable to embedded portal section of jurisdiction, shield construction tunnel plucking device.
Background technology
At present, in constructing metro tunnel, especially with in the subway tunnel of shield construction, shaping tunnel portal generally has two kinds of forms: embedded and raised type, embedded is comparatively common a kind of portal form, just need to pull out the section of jurisdiction of portal after portal ejection for water plugging construction, and the section of jurisdiction of embedded portal is generally partially submerged into tunnel internal, this just causes certain difficulty to pulling out these sections of jurisdiction.Traditional portal section of jurisdiction is pulled out needs first erection construction platform on scaffold, then in order to remove nullring section of jurisdiction, the ring flat-plate used when first need remove shield launching, fan-shaped pressing plate and ring-shaped rubber plate, then carry out behind, nullring section of jurisdiction filling mortar to cut, remove mortar and bond constraint, finally carry out section of jurisdiction dismounting, also first up and then down principle should be followed when removing in section of jurisdiction, when removing each section of jurisdiction, first in the tunnel of portal, arrange two cucurbits along direction, tunnel holds this section of jurisdiction, remove the connecting bolt of this section of jurisdiction again, then straddle truck or automobile is utilized slowly to loosen and hang out section of jurisdiction.Dismounting difficulty in conventional method section of jurisdiction is large as can be seen here, dangerous large, in unloading process, special messenger also will be arranged to be responsible for site safety management, this just makes to pull out in construction in embedded portal section of jurisdiction to need to drop into larger material resources, human input, and construction is slowly, complicated operation.
Summary of the invention
The utility model is in order to solve when with shield construction operation, embedded portal section of jurisdiction is pulled out and need be consumed a large amount of manpower and materials and financial resources and construction slowly, the problem of complicated operation, provides one and is applicable to embedded portal section of jurisdiction, shield construction tunnel plucking device.
The utility model adopts following technical scheme to complete:
One is applicable to embedded portal section of jurisdiction, shield construction tunnel plucking device, it is characterized in that: comprise steel plate I, steel plate II, steel plate III and steel plate IV, steel plate II is with the orthogonal setting of steel plate III and be welded to connect, steel plate I is arranged at steel plate II with on the reverse extending of the angular bisector of steel plate III joint angle, steel plate I have the breach that can insert steel plate II and steel plate III and be all welded to connect with steel plate II and steel plate III, the other end of steel plate III welds with steel plate IV and angle 120 ° between the two, steel plate IV and steel plate II are positioned at steel plate III homonymy, the opposite side of steel plate I, steel plate I has the hole for hoist be connected with lifting machine, steel plate II and steel plate IV have the bolt hole be connected and fixed with section of jurisdiction.
During use, the utility model is connected firmly with lifting machine, current dismounting block section of jurisdiction respectively.
The beneficial effects of the utility model are: when using the utility model lifting operation, as required embedded portal endless tube sheet gradation dismounting can be extracted, convenient and safely can complete and extract the operation of portal endless tube sheet, convenient operation, overcome the lifting of the portal endless tube sheet domain from great, the difficulty that dismounting is inconvenient.Make section of jurisdiction pull out construction operation simultaneously and become safer, economical, easy to operate.The utility model design is ingenious, and structure is simple, easy to make, uses flexibly, does not need to spend a large amount of manpowers, material resources, convenient and quick construction, simple to operate.

Detailed description of the invention
As shown in Figure 1, one is applicable to embedded portal section of jurisdiction, shield construction tunnel plucking device, comprise steel plate I 1, steel plate II 2, steel plate III 3 and steel plate IV 4, steel plate II 2 is with the orthogonal setting of steel plate III 3 and be welded to connect, steel plate I 1 is arranged at steel plate II 2 with on the reverse extending of the angular bisector of steel plate III 3 joint angle, steel plate I 1 have the breach that can insert steel plate II 2 and steel plate III 3 and be all welded to connect with steel plate II 2 and steel plate III 3, the other end of steel plate III 3 welds with steel plate IV 4 and angle 120 ° between the two, steel plate IV 4 and steel plate II 2 are positioned at steel plate III 3 homonymy, the opposite side of steel plate I 1, steel plate I 1 has the hole for hoist be connected with lifting machine, steel plate II 2 and steel plate IV 4 have the bolt hole be connected and fixed with section of jurisdiction.
The utility model use procedure:
1) bolt hole in steel plate II 2 and steel plate IV 4 coordinates segment bolt to use, and this device and portal ring current dismounting block section of jurisdiction are connected firmly;
2) hole for hoist in steel plate I 1 and lifting machine steel cable are firmly linked together.Generally do not adopt single-point to lift by crane in view of the lifting of portal section of jurisdiction and adopt 2 liftings more, need 2 the utility model devices to use Gu general, it is identical that it connects using method simultaneously;
3) connecting bolt between current dismounting block section of jurisdiction and adjacent block, adjacent ring section of jurisdiction is removed, afterwards safety lifting on request;
Other rest block portal endless tube sheet is pressed same method and is removed.
