Abstract

The utility model relates to a water supply and drainage pipeline cup joints subassembly, concretely relates to a lantern ring subassembly in glass steel for pipeline rehabilitation. The main technical problem that the maintenance cost is high, the construction is inconvenient who exists among the current pipeline rehabilitation that solves. The utility model provides a: a lantern ring subassembly in glass steel for pipeline rehabilitation, includes the interior lantern ring, characterized by the interior lantern ring is axial open -ended " C " type FRP pipe, and the interior lantern ring is equipped with waterproofing membrane with waiting to repair the pipeline enclosure, and the interior lantern ring " C " type opening part has inlayed the wedge, and the wedge passes through resin bonding agent layer sealing connection structure as an organic whole with the interior lantern ring. The utility model discloses mainly used water supply and drainage pipeline is local to be restoreed.

Description

A kind of glass fibre reinforced plastics inner sleeve assembly for pipeline rehabilitation
Technical field
The utility model relates to water supply and sewerage pipeline cover connected components, is specifically related to a kind of glass fibre reinforced plastics inner sleeve assembly for pipeline rehabilitation.The utility model is mainly used in water supply and sewerage pipeline local route repair.
Background technique
Along with the develop rapidly of urban construction, the Pipeline damage situation caused due to various factors in underground pipe network displays day by day.From existing investigation situation, except some use the old pipeline having reached 20-30 to occur burn into damage, because local geological condition is poor etc. also there is structural and functional damage phenomenon that degree is different in reason to some newly-built pipelines, had a strong impact on the safety of urban water supply system.
Current domestic pipeline non-excavation repairing technique mainly contains grouting in soil mass method, short tube Internal Lining Method, local Internal Lining Method etc.Apply the around-France and liner inversion system of comparatively general stainless steel sleeve, the former constructs inconvenience work surface limitation simultaneously, and the latter also exists deficiencies such as maintenance expenses is high, internal lining pipe rigidity is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of glass fibre reinforced plastics inner sleeve assembly for pipeline rehabilitation, mainly solves the technical problem that the maintenance expenses existed in existing pipeline rehabilitation is high, construction is inconvenient.
For achieving the above object, the technical solution of the utility model is: a kind of glass fibre reinforced plastics inner sleeve assembly for pipeline rehabilitation, comprise inner sleeve, it is characterized in that described inner sleeve is " C " type Glass Steel Tube of axially open, inner sleeve and pipeline enclosure to be repaired are provided with waterproofing membrane, inner sleeve " C " type opening is embedded with wedge-shaped blocks, and wedge-shaped blocks and inner sleeve are tightly connected by resin bonding oxidant layer and are structure as a whole.
Inner sleeve external diameter is not less than internal diameter of the pipeline to be repaired.For ensureing that Glass Steel Tube can enter pipeline to be repaired smoothly from well head, every section of inner sleeve length is no more than 0.8m.Wedge-shaped blocks has 5-10 degree to wedge angle in the axial direction.
As longer in pipeline to be repaired need combination by several sections of " C " type glass fibre reinforced plastics inner sleeves is repaired, its jointing Placement: inner sleeve and inner sleeve interface are sealed by water swelling rubber ring, namely a slice water swelling rubber ring is pre-installed at " C " type glass fibre reinforced plastics inner sleeve end face, rubber ring width is 150-200mm, sealing is implemented again to make ready-made wedge shape sealing ring in advance, the mode that wedge shape sealing ring holds round after also taking opening, takes resin base adhesives layer to be tightly connected between cambridge ring and inner sleeve.
Advantageous Effects of the present utility model is: inner sleeve adopts Parts Made of Composite Glass, reduce maintenance cost, by " C " type glass fibre reinforced plastics inner sleeve, waterproofing membrane, expansion screw and resin base Bond coupling, inner sleeve can be fitted tightly with pipeline to be repaired, and efficiency of construction improves greatly.

Embodiment
With reference to Fig. 1-3, a kind of glass fibre reinforced plastics inner sleeve assembly for pipeline rehabilitation, comprise inner sleeve 2, described inner sleeve is " C " type Glass Steel Tube of axially open 3, inner sleeve 2 selects the Glass Steel Tube of different-stiffness according to the destructiveness of pipeline 1 to be repaired, and Glass Steel Tube can adopt pure glass fibre reinforced plastics or clamp sand pipe.Fiber reinforced plastic pipe external diameter is not less than internal diameter of the pipeline to be repaired.For ensureing that Glass Steel Tube can enter pipeline 1 to be repaired smoothly from well head, every section of inner sleeve 2 length is no more than 0.8m.Glass Steel Tube is cut open vertically and excises width segments section of jurisdiction, cut-out makes pipe ring present " C " word opening 3 in the axial direction, with tying up steel band 4, " C " type glass fibre reinforced plastics inner sleeve is tightened the 0.85-0.9D making its internal diameter be contracted to pipeline to be repaired, so that " C " type glass fibre reinforced plastics inner sleeve pulls pipe interior to be repaired smoothly into." C " type opening part is arranged upward.After " C " type glass fibre reinforced plastics inner sleeve puts in place, lay one deck waterproofing membrane 5 at its top, film extends downwardly into inner sleeve and pipeline faying surface to be repaired by top.Cut off and tie up steel band 4, the glass fibre reinforced plastics inner sleeve resilience of " C " type and pipeline to be repaired are fitted.For ensureing that " C " type glass fibre reinforced plastics inner sleeve and pipeline to be repaired are fitted more closely, expansion screw 10 can be used further by " C " type glass fibre reinforced plastics inner sleeve stretching, pre-processed wedge-shaped blocks 6 is wedged " C " type ring opening 2 place along opening simultaneously, for ensureing that wedge-shaped blocks is wedged smoothly, wedge-shaped blocks can retain 5-10 degree wedging angle in the axial direction.It is bonding that wedge-shaped blocks 6 and " C " type glass fibre reinforced plastics inner sleeve adopt resin-based binder layer 7 to carry out, and uses expansion screw 10 stretching simultaneously, after complete bonding solidification, remove screw rod tightening device.
As longer in pipeline to be repaired need combination by several sections of " C " type glass fibre reinforced plastics inner sleeves is repaired, its jointing need do water-proofing treating, concrete scheme is as follows: pre-install a slice water swelling rubber ring 8 at " C " type glass fibre reinforced plastics inner sleeve end face, water swelling rubber ring 8 width is 150-200mm, sealing is implemented again to make ready-made wedge shape sealing ring 9 in advance, the mode that cambridge ring holds round after also taking opening, takes resin base binder to be tightly connected between cambridge ring and inner sleeve.
