Fig. 1 illustrates that the head being applied to the construction of pipe curtain of a kind of case of the present invention can withdraw formula push-bench, and it comprises:
Outer tube 1, as shown in Figure 1, described outer tube 1 comprises,
Support housing 11, described support housing 11 is steel shell; Support housing is the steel shell of the head external support soil body, bears the top power regulating oil cylinder simultaneously.
Regulate oil cylinder 12, described adjustment oil cylinder 12 is connected to the rear end of described support housing 11, as shown in Figure 5;
Steel pipe top entrance lip mouth 13, described steel pipe top entrance lip mouth 13 is arranged on the front end of support housing 11; Steel pipe top entrance lip mouth 13 is for cutting soil.
Rail plate 14, described rail plate 14 is arranged on the bottom of support housing inner chamber;
Band 15; As shown in Figure 4.
Push-bench also comprises: head 2, on the rail plate that described head 2 is removably mounted on outer tube 14, for excavating the soil body and being transported by dregs; In a kind of case, head 2 is connected by telescopic oil cylinder 26 with the support housing 11 of outer tube, as shown in Figure 7.Head is connected with outer tube oil cylinder, can carry out head relative to the mode of operation regulating to change push-bench before and after the small distance of outer tube.
Described band 15 is arranged between support housing 11 and head 2, is formed as stopping that the dregs under the cutterhead cutting of head enters the structure in head and outer tube gap.
Can withdraw in formula push-bench at the head being applied to the construction of pipe curtain as above of the present invention, described head 2 comprises:
Cutterhead 21, as shown in figures 3 and 8, described cutterhead 21 is provided with cutter 22 of backbreaking; In a kind of case, described in cutter 22 of backbreaking be set to stretch along cutterhead 21 radial direction.Cutter of backbreaking can be backbreak in right amount to the soil body when backbreaking work pattern and be reduced jacking resistance.In addition, described head can pass through from outer tube inside when cutter of backbreaking is regained completely, to reach the function that head can withdraw.
Main shaft reductor 23, described main shaft reductor 23 is connected with described cutterhead 21, exporting, driving the cutterhead circumgyration incision soil body for rotary power being carried out deceleration;
Helix transporting device, the dregs that described helix transporting device produces for discharging cutterhead cutting soil.In a kind of case, described helix transporting device comprises helical conveyor 24 and deslagging reductor 25, and described deslagging reductor 25 drives helical conveyor 24 to run.
Head the present invention being applied to as above to the construction of pipe curtain can withdraw formula push-bench and improves further, and described head also comprises dregs stirring rod 27, and described dregs stirring rod 27 is fixed in the card of described cutterhead 21.Dregs is stirred in the effect of dregs stirring rod 27, makes dregs enter helical conveyor smoothly.
Head the present invention being applied to as above to the construction of pipe curtain can withdraw formula push-bench and improves further, and push-bench also comprises deviation-rectifying system 3, and described deviation-rectifying system 3 comprises:
Generating laser 31, described generating laser 31 is arranged on the rock-steady structure of push-bench rear end, for transmitted reference luminous point;
Survey polarisation target 32, for receiving benchmark luminous point;
Correction oil cylinder 33, described correction oil cylinder 33 is arranged between the support housing 11 of outer tube and head 2, for adjusting the jacking direction of head.In the preferred case of one, oil cylinder has 4, and distribution is fixed on four orientation up and down of support housing, the adjustable Handpiece Location when finding that jacking orientation and planned course are misfitted, and corrects to realize jacking orientation.
Laser transmitter projects goes out benchmark luminous point.When described luminous point is positioned at the survey polarisation pinwheel of outer tube front end, jacking orientation and planned course match, and when luminous point departs from light target center, actual jacking orientation and planned course are misfitted, and need to utilize correction oil cylinder to carry out the adjustment of head tunneling direction.
The above-mentioned head being applied to the construction of pipe curtain of the present invention can withdraw formula push-bench three kinds of mode of operations:
1, to backbreak jacking pattern: namely cutterhead exceeds outer tube, advanced cutting soil, as shown in Figure 2.
2, eat native jacking pattern: namely cutterhead is return in outer tube protection domain, by outer tube cutting edge cutting soil, carry out sediment improvement deslagging by head, as shown in Figure 6.
3, open type jacking pattern: withdraw from by head rollback, by jacking of manually slagging tap, as shown in Figure 9.
In actual items, example is applied as below with push-bench, carry out the explanation of push-bench use procedure: example project is that single hole needs successively through clay stratum, the backfill containing large-size foreign matter, stratum, three kinds, sand stratum, diameter 2.2 mitron curtain work items.
Clay stratum when initial jacking, formation stability is better, can head be made to stretch out outer tube by the telescopic oil cylinder that is connected with outer tube of regulating frame head, and stretch out backbreak cutter and outer tube and carry out backbreaking jacking with footpath, skew by surveying luminous point on polarisation target in the process of jacking judges whether the orientation of jacking and predetermined orientation coincide, as found, jacking orientation offsets downward, then adjustment correction oil cylinder make head outside inside pipe casing upwards offset, strengthen the cutting output of the outer tube top soil body, reduce the resistance of outer tube top and the soil body, thus realize outer tube and upwards rectify a deviation, adjust correction oil cylinder gradually when light target display offset reduces, when returning predetermined jacking orientation in jacking orientation, recover the initial position of head in outer tube.When jacking is to backfill position containing large-size foreign matter, first cutter of backbreaking is regained, the telescopic oil cylinder adjusted again between head and outer tube makes head to recession, jacking outer tube gradually in the process of head recession, eats native length stop jacking until reach safety.Head, by hoist engine in foundation ditch, is withdrawn from by outer tube by connection between releasing head and outer tube fast, forms open type jacking pattern, can by the larger backfill in artificial treatment front under this jacking pattern.When jacking is to sand stratum, the inner foreign material of cleaning outer tube, head is advanced to initial position by the telescopic oil cylinder be connected with outer tube by head, because poor needs employing is stablized on sand stratum eat native jacking pattern, at this moment the telescopic oil cylinder between head and outer tube is adjusted, make head be retracted into outer tube inside, start to eat the jacking of native jacking pattern.After reaching the predetermined jacking degree of depth, being connected with flexible between outer tube by removing head, being recalled by head in outer tube, now single hole construction terminates, and head can be cycled to repeat use in next construction.
Each technical characteristic of above-mentioned disclosure is not limited to that disclosed with combination that is further feature, other combination that those skilled in the art also can carry out between each technical characteristic according to the object of invention, is as the criterion with the object realizing the present invention.
