Description
Technical field
The present invention relates to constructing tunnel equipment technical field more particularly to a kind of ejector sleeve mechanisms.
Background technique
When stratum Horizontal Freezing is constructed, it is necessary to a large amount of horizontally extending freezing hole is set in the earth formation,
Conventional freezing hole hole depth meter is differed from several meters to tens.Metal freezing pipe is installed in freezing hole, and (freezing pipe is generally by 2 meters of fixed length
Seamless steel pipe welding lengthens), as shown in Figure 1, beating from the first subterranean tunnel 1 ' to the second subterranean tunnel 2 ' along water surface direction
The freezing hole of extension, freezing pipe 3 ' pass through stratum 4 ', and freezing pipe 3 ' connects refrigeration unit by refrigerating medium circulating pipe system 5 ',
Then refrigerating medium is recycled in freezing pipe 3 ' and refrigerating medium circulating pipe system 5 ', by the heat transfer in stratum 4 ' to refrigeration machine
Group 6 ', refrigeration unit 6 ' is dissipated the heat to the air by cooling water recirculation system again, so that realizing reduces formation temperature simultaneously
Gradually freeze.
In the construction of entire consolidation by freezing, the construction of freezing pipe is a mostly important procedure, the matter of freezing hole construction
Amount control and risk control determine the success or failure of entire consolidation by freezing engineering.
Currently used freezing hole construction method is drilling machine pipe-following drilling method and rammer tube method.
As shown in Fig. 2, drilling machine pipe-following drilling method uses following scheme：In 3 ' head tipped drill 7 ' of freezing pipe and check-valves
8 ', freezing pipe 3 ' connects drilling machine 13 ', and drilling machine 13 ' drives the rotary drilling into stratum of freezing pipe 3 '；It must be in freezing pipe when drilling
Injection recirculated waters are after perhaps mud recirculated water or mud enter from 3 ' oral area of freezing pipe and reaches 3 ' head of freezing pipe in 3 ', top
It opens check-valves 8 ' and enters stratum afterwards, flowed out then along 3 ' outer wall of freezing pipe, playing lubricating action reduces when freezing pipe 3 ' is crept into
Frictional resistance, arrow direction is the flow direction of recirculated water or mud in Fig. 2.
Due to all necessary recirculated water of the overall process crept into freezing pipe 3 ' or mud, the silt flow being easy to cause in stratum
It loses, to be easy to cause stratum settlement, influences the safety of top building 14 '.
As shown in figure 3, ramming tube method uses following scheme：Setting pressing device 9 ' and ball valve 10 ' in the tail portion of freezing pipe 3 ',
The work of air compressor machine 11 ' generates compressed air, does power with compressed air, tamping tube hammer 12 ' is driven to move reciprocatingly and generate impact
Freezing pipe 3 ' is gradually rammed into stratum in 3 ' oral area of freezing pipe by power, impact force action；Since freezing pipe does not have to rotation, dress is compressed
Setting 9 ' can effectively be sealed, and prevent water burst sand leakage.This method can effectively solve freezing hole compared to drilling machine pipe-following drilling method
Water burst sand leakage problem in work progress not will cause stratum settlement, reduce freezing hole construction risk.
But the impact force of tamping tube hammer 12 ' is possible to will cause at 3 ' welding point of freezing pipe and generates stealthy crack, later period
During Freezing stratum as rapid, under black brittleness effect, freezing pipe 3 ' is easy to cause to be broken, so that refrigerating medium miss event is caused,
Risk is brought to Freezing stratum as rapid.The frictional resistance that tube method overcomes freezing pipe 3 ' outer wall and stratum by impact force is rammed, with freezing pipe
Depth becomes larger, and frictional resistance is also increasing, and it is also slower and slower to ram pipe speed；Tamping tube hammer weight is big, mobile inconvenient, worker's labour
The high fatiguability of intensity.Due to ramming tube method work progress there are high altitude operation, personal safety risk when constructing is higher.
Therefore, when carrying out the construction of stratum Horizontal Freezing, how water burst sand leakage not only can be effectively solved the problems, such as, but also can subtract
Few influence to freezing pipe weld seam, becomes those skilled in the art's technical problem urgently to be resolved.
