Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples.
Refering to fig. 1, the present invention provides a kind of main jacking mechanism of pipe curtain subsurface excavation method jacking construction, it is arranged in active well It is interior, for realizing the jacking and control of tube coupling.Main jacking mechanism of the invention provides auxiliary propulsion for small-bore pipe curtain push-bench Tube coupling construction, avoids the rollback of tube coupling in progradation and slows down under tube coupling tube coupling front because caused by head quality is big The phenomenon that inclining solves the problems, such as that the time for needing to convert pipeline when the existing jacking block propulsion using circle repeatedly digests, improves and apply Work efficiency rate.The structure of the main jacking mechanism of pipe curtain subsurface excavation method jacking construction of the present invention is illustrated with reference to the accompanying drawing.
Refering to fig. 1, it is shown that the structural schematic diagram of the main jacking mechanism of pipe curtain subsurface excavation method jacking construction of the present invention.It ties below Fig. 1 is closed, the structure of the main jacking mechanism of pipe curtain subsurface excavation method jacking construction provided by the invention is illustrated.
As shown in Figure 1, a kind of main jacking mechanism 20 of pipe curtain subsurface excavation method jacking construction provided by the invention include pedestal 21, By 22, propulsion assembly 23, power mechanism 24, portal frame 25 and stopping mechanism 26 after fixation, wherein pedestal 21 is main jacking dress The other component for setting 20 provides the basis of support installation, and the pedestal 21 is for being placed on loading end, in use, main jacking mechanism 20 are placed in the starting well in tunnel, and pedestal 21 is placed in the bottom of starting well.It is connected by 22 with pedestal 21 after fixation, this is fixed It is rear by offseting with active well by 22 afterwards, it is provided for main jacking mechanism 20 and firm shores basis.Promote assembly 23 movably Be slidably installed on pedestal 21, the propulsion assembly 23 after fixed by 22 settings, promote assembly 23 be set to it is fixed after lean on 22 front side, And it can be moved forward and backward along the setting direction of pedestal 21.Power mechanism 24, which is installed in, to be promoted on assembly 23, the power mechanism 24 also 22 connects with leaning on after fixation, are pushed by power mechanism 24 and promote assembly 23 along pedestal 21 to far from leaning on 22 after fixed Direction is mobile, promotes assembly 23 to push the jacking into Tunnel of tube coupling 10 when mobile.Portal frame 25 is installed on pedestal 21 and position In the front for promoting assembly 23, when promoting the jacking tube coupling 10 forward of assembly 23, which passes through portal frame 25 and enters In Tunnel.Stopping mechanism 26 is installed on portal frame 25, which is telescopically adjustable structure, in conjunction with Fig. 7 institute Show, stopping mechanism 26 is equipped with serrated face 261 compatible with tube coupling 10, makes the saw by the telescopic adjustment of stopping mechanism 26 The flank of tooth 261 is tightly attached to the lateral surface of tube coupling 10 to limit the rollback of tube coupling 10.The jacking tube coupling forward of assembly 23 is promoted utilizing After 10, the maximum displacement for promoting assembly 23 that tube coupling 10 is pushed to reach forward movement at this time adjusts stopping mechanism 26 to close to pipe The direction of section 10 is mobile, so that serrated face 261 is tightly attached to the lateral surface of tube coupling 10, then will promote assembly using power mechanism 24 23 are moved to original position, during promoting the mobile return of assembly 23, tube coupling 10 due to there is the pressuring action of stopping mechanism 26, and The phenomenon that rollback will not be generated, so that having well solved tube coupling and having retracted leads to the problem of jacking precision controlling hardly possible.In addition The stopping mechanism 26 and portal frame 25 implement pressuring action to the rear portion of the tube coupling 10 in jacking tunnel hole together, so that the tube coupling 10 rear portion structural stability with higher can slow down the phenomenon that big caused whole tube coupling of head quality has a down dip, this hair Bright main jacking mechanism 20 can guarantee that stablizing for tube coupling 10 promotes, securely and reliably.
