The present invention relates to the tunnel tightening device used in subway work process, specifically a kind of shield duct piece fastening devices, comprise a circular steelframe body, described steelframe body comprises outer ring and inner ring, and described outer ring is connected by some support bars with between inner ring, between described outer ring and inner ring, be provided with guide strip in pairs, between every a pair guide strip, all leave hole for hoist.For in prior art, when constructing tunnel, the shield duct piece ring in stretching tunnel, lean on the mutual pressure of each shield duct piece joint to reach the stretching object of shield duct piece completely, what the invention provides a kind of shield duct piece holds out against bracing or strutting arrangement, and this apparatus structure is rationally ingenious, cheap, for bracing reinforcement tunnel shield duct piece effect but clearly, use this device can the shield duct piece of effective Strengthening Tunnel, eliminate safe hidden trouble.
Description
Technical field
The present invention relates to the tunnel tightening device used in subway work process, specifically a kind of shield duct piece fastening devices.
Background technology
Shield duct piece is the main mounting structure of shield-tunneling construction, is the outermost layer barrier in tunnel, carries the effect of opposing earth pressure, groundwater pressure and some special loads.Shield duct piece is the permanent lining, secondary lining structure of shield tunnel, and the quality of shield duct piece is directly connected to total quality and the safety in tunnel, affects water resistance and the endurance quality in tunnel.The production of shield duct piece adopts high-strength water-tight concrete usually, and to guarantee reliable load and water resistance, Commercial cultivation production tube die is namely plastic after sealing placing of concrete.
At present, in constructing tunnel process, after the cutter head of shield machine leading section has excavated tunnel, directly by the section of jurisdiction supply system of shield machine and section of jurisdiction automatic assembling device, shield duct piece is become circular and be arranged in tunnel, played a supporting role; This support undertaken by shield duct piece is convenient and swift, carry stressed by adjacent two shield duct piece joints completely between each shield duct piece in each annulus, although the splicing structure work progress of this shield duct piece is convenient and swift, but the circular braced structures entirety be assembled into lacks bracing or strutting arrangement, cause tunnel perimeter have significantly surface vibration time, there is shield duct piece and come off and the danger causing Tunnel Landslide.
Summary of the invention
The present invention is directed to the problems referred to above, a kind of shield duct piece fastening devices is provided, adopt this device can effective reinforcing shield section of jurisdiction, avoid the risk of Tunnel Landslide.
According to technical scheme of the present invention: a kind of shield duct piece fastening devices, it is characterized in that: comprise a circular steelframe body, described steelframe body comprises outer ring and inner ring, and described outer ring is connected by some support bars with between inner ring, between described outer ring and inner ring, be provided with guide strip in pairs, between every a pair guide strip, all leave hole for hoist.
As a further improvement on the present invention, the extended line of support bar described in every root is all by the center of circle of steelframe body.
As a further improvement on the present invention, the length of described support bar is equal with the radical length of shield duct piece, and the axial width of steelframe body is equal with the thickness of shield duct piece.
Technique effect of the present invention is: in prior art, when constructing tunnel, the shield duct piece ring in stretching tunnel, lean on the mutual pressure of each shield duct piece joint to reach the stretching object of shield duct piece completely, what the invention provides a kind of shield duct piece holds out against bracing or strutting arrangement, and this apparatus structure is rationally ingenious, cheap, for bracing reinforcement tunnel shield duct piece effect but clearly, use this device can the shield duct piece of effective Strengthening Tunnel, eliminate safe hidden trouble.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, comprise steelframe body 1, hole for hoist 2, outer ring 3, inner ring 4, support bar 5 etc.
As shown in Figure 1, the present invention is a kind of shield duct piece fastening devices, comprise a circular steelframe body 1, described steelframe body 1 comprises outer ring 3 and inner ring 4, and described outer ring 3 is connected by some support bars 5 with between inner ring 4, for effectively strengthening the stability of steelframe body 1, in the manufacture process of steelframe body 1, usually the extended line of support bar 5 described in every root is all by the center of circle of steelframe body 1, guide strip is provided with in pairs between described outer ring 3 and inner ring 4, hole for hoist 2 is all left between every a pair guide strip, not only make steelframe body 1 to reserve the hole for hoist 2 for facilitating steelframe body 1 to lift by the guide strip added, also further enhance the stability between steelframe body 1 outer ring 3 and inner ring 4.
In order to effectively fix the shield duct piece in tunnel, steelframe body 1 also needs to meet following condition further: the length of support bar 5 is equal with the radical length of shield duct piece, and the axial width of steelframe body 1 is equal with the thickness of shield duct piece, the inner ring 4 of steelframe body 1 can be the steelframe of annular also can be annular steel plate structure, outer ring 3 comprises two annular steel rings, and two annular steel rings are fixedly connected on the end of the support bar 5 at steelframe body 1 through-thickness two ends respectively, this structure makes the middle part of the outer ring 3 of steelframe body 1 be annular hollow structure, namely, form an annular groove, when being supported in when steelframe body 1 on the shield duct piece in tunnel, the support bar 5 of steelframe body 1 both sides protects and is loaded on shield duct piece two ends, the inner ring 3 of steelframe body 1 holds out against on the inwall of shield duct piece, reach the effect of stretching tunnel inner wall.
For in prior art, when constructing tunnel, the shield duct piece ring in stretching tunnel, lean on the mutual pressure of each shield duct piece joint to reach the stretching object of shield duct piece completely, what the invention provides a kind of shield duct piece holds out against bracing or strutting arrangement, and this apparatus structure is rationally ingenious, cheap, for bracing reinforcement tunnel shield duct piece effect but clearly, use this device can the shield duct piece of effective Strengthening Tunnel, eliminate safe hidden trouble.
