Abstract
The utility model discloses a regular polygon prestressing force support for preventing circular tunnel deformation of side opening, this support are sealed by at least three isosceles triangle truss end to end and form, the summit of isosceles triangle truss outwards, adjacent two triangular truss adopts bolt and welding hybrid connection's mode to connect, adjacent two the outside of isosceles triangle truss connection department and at every the summit of isosceles triangle truss department all is equipped with output jack outwards be connected with the backup pad on the output of jack. The utility model discloses a process the regular polygon structure of equipment in member, the hole outside the hole, stable in structure, the atress is even, and intensity, rigidity are reliable, the additional deformation that can control channel excavation process produces tunnel segment, the opening both sides tunnel segment safety of guaranteeing to incline, installation, dismantlement convenience, labour saving and time saving, repeatedly usable after the dismouting can reduce cost, and economical and practical is worth promoting in tunnel construction.
Description
Technical field
The utility model is related to a kind of prestress stent for preventing tunnel deformation, particularly a kind of for preventing side opening from justifying
The regular polygon prestress stent of shape tunnel deformation.
Background technology
Service channel is generally set between two Parallel Tunnels of city underground, and service channel plays connection, draining and fireproof
Effect.Section is rectangle, circular or stalk arch, typically located at running tunnel middle part.Construction method can adopt cut and cover method, the soil body
Reinforce subsurface excavation method, pipe shed method and small-sized shield method etc..Freezing process wherein in soil stabilization subsurface excavation method is gradually employed in recent years
In Urban Metro Construction.The Construction Principle of freezing process is：Using refrigeration piping by freezing soil on the outside of service channel, formed and frozen
Knot wall, it is ensured that top and side soil layer are stablized during ground settlement and tunnel.But need dismounting passage attached in ground settlement and tunnel process
The tunnel duct piece constructed in nearly tunnel, therefore need to arrange in the tunnel local positioned at passage both sides before service channel is excavated
Interim prestress stent, with the additional deformation that control passage digging process is produced to tunnel duct piece, it is ensured that the position section of jurisdiction safety.
The content of the invention
The utility model provides a kind of for preventing side opening circular to solve technical problem present in known technology
The regular polygon prestress stent of tunnel deformation, the support being capable of the additional change that produces to tunnel duct piece of control passage digging process
Shape, it is ensured that side opening both sides tunnel duct piece safety.
The utility model is adopted the technical scheme that to solve technical problem present in known technology：One kind is used to prevent
The regular polygon prestress stent that only side opening circular tunnel deforms, the support is by least three isosceles triangle truss head and the tail phases
Even closing is formed, and outwardly, two adjacent triangular trusses are using bolt and weldering on the summit of the isosceles triangle truss
The mode for connecing Hybrid connections connects, in the outside of two adjacent isosceles triangle truss junctions and described in each
The apex of isosceles triangle truss is equipped with output end jack outwardly, is connected with the output end of the jack
Gripper shoe.
The isosceles triangle truss is welded using channel-section steel.
The isosceles triangle truss has 4.
M shape support is welded with the support.
The utility model has the advantages and positive effects that：Using the regular polygon assembled in tooling member outside hole, hole
Structure, Stability Analysis of Structures, uniform force, intensity, rigidity reliability, can control passage digging process tunnel duct piece generation is added
Deformation, it is ensured that side opening both sides tunnel duct piece safety；Installation, convenient disassembly are time saving and energy saving；It is reusable after dismounting, energy
Enough reduces costs, it is economical and practical, it is worth being promoted in constructing tunnel.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure：1st, isosceles triangle truss；2nd, jack；3rd, gripper shoe.
Specific embodiment
For the content of the invention of the present utility model, feature and effect can be further appreciated that, following examples are hereby enumerated, and coordinated
Accompanying drawing describes in detail as follows：
Refer to Fig. 1, a kind of regular polygon prestress stent for preventing side opening circular tunnel from deforming, the support by
The closing that joins end to end of at least three isosceles triangle truss 1 is formed, and the summit of the isosceles triangle truss 1 is outwardly, adjacent
Two triangular trusses 1 are connected by the way of bolt and welding Hybrid connections, in two adjacent isoceles triangles
The outside of the junction of shape truss 1 and it is equipped with an output end outwardly in the apex of each isosceles triangle truss 1
Jack 2, is connected with gripper shoe 3 in the output end of the jack 2.
In the present embodiment, the isosceles triangle truss is welded using channel-section steel.The isosceles triangle purlin
Frame has 4.In order to strengthen support of tunnel, M shape support can be welded in the support.
When using, two Pin prestress stents, two adjacent Pin prestressing force in tunnel are respectively set in the side opening both sides in tunnel
Can do longitudinally connected using angle steel between support, to guarantee the stability of prestress stent.
Although being described to preferred embodiment of the present utility model above in conjunction with accompanying drawing, the utility model is not
Above-mentioned specific embodiment is confined to, above-mentioned specific embodiment is only schematic, is not restricted, ability
The those of ordinary skill in domain under enlightenment of the present utility model, without departing from the utility model objective and claimed
In the case of scope, many forms can also be made, these are belonged within protection domain of the present utility model.
