Description
Technical field
The present invention relates to subway construction technical field of construction, more particularly to a kind of metro shield section of jurisdiction.
Background technology
Construction of subway typically uses shield-tunneling construction, and shield duct piece is the main mounting structure of shield-tunneling construction, be tunnel most
Internal layer barrier, the effect of resistance earth pressure, groundwater pressure and some special loads is carry, shield duct piece is shield method
The permanent lining, secondary lining structure in tunnel, shield duct piece quality are directly connected to the total quality and safety in tunnel, influence the waterproof in tunnel
Performance and endurance quality.Existing shield duct piece typically uses the lamellar body structure of circular arc, and seals waterproof, structure by sealing strip
Support strength is relatively weak, and installation is complex.
The content of the invention
It is an object of the invention to provide a kind of metro shield section of jurisdiction, to solve above-mentioned technical problem.
The present invention uses following technical scheme to achieve the above object：
A kind of metro shield section of jurisdiction, including：Lamellar body, piece ridge, convex platform, lower convex platform, through hole, bolt slot, the first waterproof layer, second
Waterproof layer, buttcover plate, it is characterised in that：The lamellar body is circular arc lamellar body, and the axis of its inner surface is provided with piece ridge, institute
The inner surface for stating lamellar body has bolt slot in four edges, and the anterior end surface and back end surface of the lamellar body are equipped with
Buttcover plate, the both ends difference connecting bolt groove and buttcover plate of the through hole, the upper surface of the lamellar body are provided with convex platform, described
The lower surface of body is provided with lower convex platform, and the first waterproof is equipped with the outer surface of the convex platform and the interior survey surface of lower convex platform
Layer, it is equipped with the second waterproof layer in the periphery of buttcover plate on the front and rear end of the lamellar body.
On the basis of above-mentioned technical proposal, the lamellar body using high-strength water-tight concrete make, the convex platform, under it is convex
Platform, piece ridge and piece body by integral forming.
On the basis of above-mentioned technical proposal, first waterproof layer and the second waterproof layer are made using rubber.
On the basis of above-mentioned technical proposal, the end face of described ridge and the surface of buttcover plate at grade, described
Two waterproof layers slightly protrude from plane where the end face of piece ridge and the surface of buttcover plate.
On the basis of above-mentioned technical proposal, the circular arc of the lamellar body is 1/8 circle, is connected between two lamellar bodies by arch screw bolt
Connect fixation.
Compared with prior art, the present invention has advantages below：The inner surface of the present invention is provided with piece ridge, identical heavy
There is more preferable support force, structural stability is more preferable under the weight concrete of amount；Waterproof layer, waterproof are equipped with four connection sides
Performance is more preferable；Installed using upper lower convex platform crimping mode, installation is simple, improves efficiency of construction, overall structure is more stable, resistance to stress
Effect is more preferable.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the arch screw bolt attachment structure schematic diagram of the present invention.
Fig. 3 is the curved end connection diagram of the present invention.
In figure：1st, lamellar body, 2, piece ridge, 3, convex platform, 4, lower convex platform, 5, through hole, 6, bolt slot, the 7, first waterproof layer, 8,
Second waterproof layer, 9, buttcover plate, 10, arch screw bolt.
Embodiment
The present invention is further elaborated with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of metro shield section of jurisdiction, including：Lamellar body 1, piece ridge 2, convex platform 3, lower convex platform 4, through hole 5, spiral shell
Croze 6, the first waterproof layer 7, the second waterproof layer 8, buttcover plate 9, the lamellar body 1 are circular arc lamellar body, the axis of its inner surface
Line is provided with piece ridge 2, and the inner surface of the lamellar body 1 has bolt slot 6, the front side of the lamellar body 1 in four edges
End face and back end surface are equipped with buttcover plate 9, the both ends difference connecting bolt groove 6 and buttcover plate 9 of the through hole 5, the lamellar body 1
Upper surface be provided with convex platform 3, the lower surface of the lamellar body 1 is provided with lower convex platform 2, the outer surface of the convex platform 3 and under it is convex
The first waterproof layer 7 is equipped with the interior survey surface of platform 4, is equipped with the front and rear end of the lamellar body 1 in the periphery of buttcover plate 9
Second waterproof layer 8, the lamellar body 1 are made using high-strength water-tight concrete, the convex platform 3, lower convex platform 4, piece ridge 2 and lamellar body 1
It is integrally formed, the waterproof layer 8 of the first waterproof layer 7 and second is made using rubber, end face and the buttcover plate 9 of described ridge 2
Surface at grade, second waterproof layer 8 slightly protrude from piece ridge 2 end face and buttcover plate 9 surface where plane,
