Abstract
A kind of shield duct piece with joggle, including arc sheet body 1, circumferential screw channel 2, longitudinal screw channel 3, sealing strip 4, there are two tenons 6 for one end tool of arc sheet body 1, there are two tongue-and-grooves 5 for other end tool, tenon 6 and tongue-and-groove 5 are mortise, and the curvature of tenon 6 and tongue-and-groove 5 is identical as the curvature of arc sheet body 1.Shield duct piece is during installation, tenon 6 is inserted into tongue-and-groove 5, since the curvature of tenon 6 and tongue-and-groove 5 is identical as the curvature of arc sheet body 1, it is automatically aligned to the circumferential screw channel 2 of the arc at the both ends of two arc sheet bodies 1, arch screw bolt can smoothly pass through circumferential screw channel 2, the alignment difficulty for greatly reducing circumferential screw channel 2, improves arch screw bolt joint efficiency on circumferential direction, can accelerate shield process.
Description
Technical field
The present invention relates to shield techniques, and in particular to a kind of shield duct piece with joggle.
Background technique
Construction of subway generally uses shield-tunneling construction, and shield duct piece is the main mounting structure of shield-tunneling construction, be tunnel most
Internal layer barrier carries the effect for resisting earth pressure, groundwater pressure and some special loads.Shield duct piece is shield method
The permanent lining, secondary lining structure in tunnel, shield duct piece quality are directly related to the total quality and safety in tunnel, influence the waterproof in tunnel
Performance and endurance quality.Existing shield duct piece generally uses arc-shaped sheet body structure, and seals waterproof, arc by sealing strip
There is arc screw channel on sheet body circumferential direction, there is on longitudinal direction straight screw channel, arch screw bolt and straight bolt are each passed through arc screw channel and straight
The screw channel arc sheet body adjacent with fixation.In construction of subway, shield duct piece dosage is very big, due to shield narrow space, section of jurisdiction with
The fastening need of work of bolt between section of jurisdiction has been manually done, and the fastening work of bolt is to influence the important elements of construction progress.
To make bolt pass through two adjacent sections of jurisdiction, the screw channel hole on two sections of jurisdiction just needs accurate opposite.Since shield duct piece is arc
Shape also requires the screw channel smooth connection on circumferential direction that can just arch screw bolt be made to pass through, so that the screw channel hole of two shield duct pieces
Alignment work occupies the bolted most of the time.
Summary of the invention
The first purpose of this invention is to provide a kind of shield duct piece with joggle, so that the screw channel hole of shield duct piece
Faster alignment, and keep the occlusion between shield duct piece stronger, prevent section of jurisdiction annular strain.
To realize the above goal of the invention, technical scheme is as follows:
A kind of shield duct piece with joggle, including arc sheet body, circumferential screw channel, longitudinal screw channel, sealing strip, arc sheet body
Both ends also have tenon structure.
Further, arc sheet body one end has tenon, and the other end has tongue-and-groove.
Further, the both ends of the arc sheet body all have tenon and tongue-and-groove.
Further, the both ends of the arc sheet body only have tenon or tongue-and-groove.
Further, the tenon is arc tenon, and the tongue-and-groove is mortise.
Further, the curvature of the arc tenon and the mortise is identical as the curvature of the arc sheet body.
Compared with prior art, beneficial effects of the present invention: a kind of shield duct piece with joggle of the invention, both ends
With tenon structure, after tenon is inserted into tongue-and-groove, it is difficult can to substantially reduce screw channel alignment for the screw channel that can be automatically aligned between two shield duct pieces
Degree improves bolted working efficiency, accelerates shield-tunneling construction process；Two adjacent arc sections of jurisdiction pass through tenon and tongue-and-groove card
It closes, the occlusion between shield duct piece is stronger, and section of jurisdiction ring is not susceptible to deform.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the shield duct piece with joggle described in the embodiment of the present invention 1；
Fig. 2 is the structural schematic diagram of the shield duct piece with joggle described in the embodiment of the present invention 1；
Fig. 3 is the structural schematic diagram of the shield duct piece with joggle described in the embodiment of the present invention 2；
In figure 1 above -3,1- arc sheet body；2- circumferential direction screw channel；The longitudinal direction 3- screw channel；4- sealing strip；5- tongue-and-groove；6- tenon.
Specific embodiment:
The present invention is described further with reference to the accompanying drawings.
Embodiment 1
As depicted in figs. 1 and 2, a kind of shield duct piece with joggle, including arc sheet body 1, circumferential screw channel 2, longitudinal spiral shell
Slot 3, sealing strip 4, there are two tenons 6 for one end tool of arc sheet body 1, and there are two tongue-and-grooves 5 for other end tool, and tenon 6 and tongue-and-groove 5 are
Mortise, and the curvature of tenon 6 and tongue-and-groove 5 is identical as the curvature of arc sheet body 1.During installation, tenon 6 is inserted into shield duct piece
Tongue-and-groove 5 makes the arc at the both ends of two arc sheet bodies 1 since the curvature of tenon 6 and tongue-and-groove 5 is identical as the curvature of arc sheet body 1
Circumferential screw channel 2 is automatically aligned to, and arch screw bolt can smoothly pass through circumferential screw channel 2, and the alignment for greatly reducing circumferential screw channel 2 is difficult
Degree, improves arch screw bolt joint efficiency on circumferential direction, accelerates shield process.
Embodiment 2
As shown in figure 3, a kind of shield duct piece with joggle, including it is arc sheet body 1, circumferential screw channel 2, longitudinal screw channel 3, close
Strip of paper used for sealing 4, the both ends of arc sheet body 1 respectively have a tongue-and-groove 5 and a tenon 6.Tenon 6 and tongue-and-groove 5 are mortise, and tenon
First 6 and tongue-and-groove 5 curvature it is identical as the curvature of arc sheet body 1.Shield duct piece during installation, the tongue-and-groove 5 and tenon of two arc sheet bodies 1
First 6 are mutually inserted, and since the curvature of tenon 6 and tongue-and-groove 5 is identical as the curvature of arc sheet body 1, make the both ends of two arc sheet bodies 1
The circumferential screw channel 2 of arc is automatically aligned to, and arch screw bolt can smoothly pass through circumferential screw channel 2, greatly reduces circumferential screw channel 2
It is directed at difficulty, improves the joint efficiency of circumferential bolt.
