Description
Technical field
It the utility model is related to no-dig technique pipe rehabilitation technology field, more particularly to a kind of non-excavation rehabilitation caves in pipeline use
Collapsible steel loop.
Background technology
Urban duct is one of important infrastructure for supporting social development and ensureing people's lives, and pipe-line maintenance conserves
It is the necessary means for ensureing its normal mechanism and function.The repair of pipeline mainly passes through trenchless rehabilitation and non-excavation rehabilitation two
Kind repair mode carries out pipeline rehabilitation.
Trenchless rehabilitation directly excavates pipeline, then treats pipe-repairing and is repaired, and the trenchless rehabilitation of pipeline is present
Environmental problem and economic impact it is bigger, and easily cause the security incidents such as the destruction of remaining pipes.
However, non-excavation rehabilitation is for the low influence of infrastructure, the gradual attention of repair mode of low-maintenance.At present,
Method in the trenchless repairing method of existing pipeline mainly using inverted liner is repaired, and liner inversion system mainly passes through
Using the enhanced flexible pipe of composite fibre with impermeable corrosion-resistant cuticula as carrier, by carrier impregnation epoxy or unsaturated tree
After fat, power is done with water or gas, flexible pipe is close in old pipe, forms the inwall of globality in old pipe after flexible pipe solidifies
Layer, so as to reach the purpose to underground piping reparation.
But the methods of liner inversion system when not doing effective pretreatment, the reparation of pipeline section of being caved in deformation can not be realized.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of simple in construction, construction, and easily non-excavation rehabilitation collapses
Collapse the collapsible steel loop of pipeline.
Technical scheme used by solve above-mentioned technical problem：A kind of non-excavation rehabilitation caves in pipeline folding steel
Ring, including top curve steel plate, left upper portion curved plate, the left lower arc that along the circumferential direction head and the tail are hinged successively
Steel plate, bottom curved plate, lower right side curved plate and right upper portion curved plate, the left upper portion curved plate and a left side
The adjacent end portion of side lower part curved plate, which is respectively perpendicular to extend, forms connection end plate, on the lower right side curved plate and right side
The adjacent end portion of portion's curved plate is respectively perpendicular extension and forms connection end plate, and the connection end plate is provided with to be worn for bolt connection piece
Cross the bolt hole being connected.
Further, the top curve steel plate, left upper portion curved plate, left lower curved plate, bottom arc
Steel plate, lower right side curved plate and right upper portion curved plate are hinged by hinge each other.
Further, the connection end plate is provided with deep floor.
Further, the top curve steel plate and bottom curved plate middle inside are provided with support flat board.
Beneficial effect：This non-excavation rehabilitation caves in pipeline with collapsible steel loop, and collapsible steel loop is used with folded state
Rope traction enters at pipeline Collapse Deformation, passes through jack stand top curve steel plate so that collapsible steel loop expands into
Circular steel loop, casting concrete layer to form supporting construction, then carries out resin-lined construction to circular steel loop inwall again again
Resinous coat is formed, support and protection structure are used as by circular steel loop, not only ensure construction safety, moreover it is possible to reduce pipeline and repair
The thickness of resinous coat in multiple.
Brief description of the drawings
The utility model is described further with reference to the accompanying drawings and examples；
Fig. 1 is the structural representation of the utility model embodiment；
Fig. 2 is the structural representation of the utility model embodiment use state.
Embodiment
Referring to Figures 1 and 2, a kind of non-excavation rehabilitation of the utility model caves in the collapsible steel loop of pipeline, including circumferentially
Direction head and the tail be hinged successively top curve steel plate 1, left upper portion curved plate 2, left lower curved plate 3, bottom
Curved plate 4, lower right side curved plate 5 and right upper portion curved plate 6, top curve steel plate 1, left upper portion curved plate
2nd, left lower curved plate 3, bottom curved plate 4, lower right side curved plate 5 and right upper portion curved plate 6 each other it
Between formed and be articulated and connected by hinge, so as to be relatively rotated between adjacent curved plate so that six pieces of curved plates can
To form folded state.
In use, the collapsible steel loop uses the pipe deforming position of rope traction entrance in folded state, pass through thousand
Jin top 10 jacks up top curve steel plate 1 so that collapsible steel loop expands into circular steel loop, and circular steel loop inwall pours mixed again
The methods of coagulating soil layer to form supporting construction, then carrying out resin-lined or mortar spraying again completes inner liner construction, passes through circle
Ring-type steel loop can effectively, quickly recover deformable duct, improve ring stiffness, reduce inner liner thickness, while as support and protect
Protection structure, ensure construction safety.
Wherein, the adjacent end portion of left upper portion curved plate 2 and left lower curved plate 3 is respectively perpendicular extension and formed and connected
Connect end plate 7, the adjacent end portion of lower right side curved plate 5 and right upper portion curved plate 6 is respectively perpendicular extension and forms connection end
Plate 7, connection end plate 7 is provided with passes through the bolt hole being connected for bolt connection piece, when collapsible steel loop expands into annular shape
When, adjacent connecting ends plate 7 is mutually corresponding, is bolted part and is fastenedly connected through the adjacent two connection formation of end plates 7, so as to
Limit adjacent left upper portion curved plate 2 and the relative rotation of left lower curved plate 3 and lower right side curved plate 5 and the right side
Upper lateral part curved plate 6 relatively rotates so that folding steel ring keeps circular constant.Preferably, connect end plate 7 and be provided with and add
Strong floor 8, to improve the intensity for connecting end plate 7.
Preferably, the branch contacted with jack 10 is provided with top curve steel plate 1 and the middle inside of bottom curved plate 4
Flat board 9 is supportted, is easy to jack 10 to support stress.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in the technical field those of ordinary skill possessed knowledge, this practicality can also not departed from
Various changes can be made on the premise of new objective.
