It should be noted that, the shield duct piece that the negative endless tube sheet spliced in advance and shield tail are installed and jacking pipe joints connector are the key components of described push pipe and shield structure conversion equipment.Because shield tail length has certain length, and shield ventral brush is positioned at the end of shield tail, for ensureing the smooth realization of shield structure pattern, shield ventral brush encases section of jurisdiction and plays sealing function, therefore must bear endless tube sheet by assembled at least two rings, add shield structure jack length, can construction requirement be met.Described shield duct piece and jacking pipe joints connector then in from pipe jacking method to the process of shield method transition, for jacking pipe joints and shield duct piece provide transition bindiny mechanism.
Further, the middle part of described shield duct piece and jacking pipe joints connector is embedded with at least 5 one way valve injected holes.
Utilize the construction method of above-mentioned push pipe and shield structure conversion equipment, comprise the steps:
S1 completes the assembling of push-bench: install duct piece assembling machine and shield duct piece and jacking pipe joints connector in shield tail position; Shield duct piece with by pre-buried segment bolt hole, at least two rings are installed for the side being connected shield duct piece in advance in jacking pipe joints connector and bear endless tube sheet, and point to push-bench jacking direction; And the opposite side of shield duct piece and jacking pipe joints connector is connected to the jacking pipe joints that the later stage installs;
S2, by the jacking system of push-bench, carries out jacking to shaping pipe jacking tunnel, the pipe jacking tunnel in hitting the target;
S3, by set one way valve injected hole in the middle part of the reserved injected hole set by bell and spigot between the composition tube coupling of shaping pipe jacking tunnel and tube coupling and shield duct piece and jacking pipe joints connector, injects inert slurry, and adopts pair slurries shutoff portal after tube coupling wall.
It should be noted that, step S3 is one critical process that push pipe turns shield structure, because pipe jacking tunnel needs to inject drag reducer to play the effect of reduction thrust force after tube coupling wall, therefore before converting shield method to, must fill after tube coupling wall, to ensure the frictional force needed for shield driving.And step S3 plays the effect of shutoff bell and spigot and consolidation tube coupling.
S4 is attachment rail in pipe jacking tunnel, by feeding sheet machine transport section of jurisdiction to duct piece assembling machine, starting shield structure pattern, carrying out pipe sheet assembling.
It should be noted that, in step S3, described reserved injected hole is arranged on inside bell and spigot edge.
It should be noted that, the inert slurry injected in step S3 is cement grout, and the water/binder ratio of described cement grout is 1:1.
It should be noted that, in step S3, grouting pressure is 0.3Mpa-0.4Mpa.
It should be noted that, the two slurries in step S3 primarily of cement and water glass according to 1:(0.5 ± 0.05) weight ratio mix.
Beneficial effect of the present invention is:
1, the fusion for realizing merging pipe jacking method and shield method provides an effective conversion equipment and construction method, makes it possible to realize the straightway employing pipe jacking method in engineering early stage, and curved section uses shield method, thus obviously saves construction costs;
2, first take push pipe pattern, can carry out separate launching, because pipe jacking equipment is simple, row does not overlap chassis afterwards, and starting well floor space is relatively little, less on urban traffic impact.
