First, installation push pipe receives antipriming in advance, and the antipriming includes sealing heavy curtain 1, by the sealing heavy curtain 1
It is arranged on the edge for receiving hole；The sealing heavy curtain 1 forms enclosure space with push pipe outer wall, reception hole inner wall, building enclosure；Also
Including grouting pipe 2, one end of the grouting pipe 2 is connected with the enclosure space, the other end is in communication with the outside.
2nd, after pipe jacking tunnelling machine enters received well termination stabilization zone 1m, decompression step by step is started.Apart from building enclosure
During 50cm, soil pressure is reduced to 0Mpa, avoids top power from crossing the deformation of senior general's building enclosure top, causes penetrating passage.
3rd, when pipe jacking tunnelling machine is apart from building enclosure 20cm, cut off last layer of reinforcing bar of building enclosure and abolish last
One layer concrete.When cutting off building enclosure, first in center digging, then four pieces are divided to cut, easy to determine that push pipe reaches posture and section
About abolish the time.
4th, received well is entered but when not completely disengaging the soil body in pipe jacking tunnelling machine, using the grouting pipe 2 to the envelope
Injection slurries in space are closed, the sealing ring for being used for sealing is formed between hole inner wall and pipe jacking tunnelling machine receiving, prevents and gushes
Water gushes sand dangerous situation, ensures that pipe jacking tunnelling machine receives safety.The slurries are dual slurry or yellow mud.Dual slurry, i.e. two fluid grouting, will
Waterglass replaces with calcium chloride solution in injection soil, and two kinds of solution react rapidly generation silica gel and gel of calcium silicate, play glue
The effect of knot and filling pore, improves the intensity and bearing capacity of soil.
5th, after pipe jacking tunnelling machine is separated with jacking pipe joints, jacking pipe joints are blocked immediately and receive the gap between hole.
