Specific embodiment
The present invention is by reinforcement slip casting steel pipe 4, slip casting flange 7, bump joint 8, grouting pipe 9, slip casting machine 10, connecting bolt 12nd, closure 14 is constituted.
Fig. 1,2 displays, it is annular pipe to strengthen slip casting steel pipe 4, strengthens the annulus and corrugated steel pipe 1 of slip casting steel pipe 4 Circumference matches, and strengthens the excircle that slip casting steel pipe 4 is looped around corrugated steel pipe 4, strengthens the annulus of slip casting steel pipe 4 by more than 2 sections Arc-shaped steel tube is constituted, and is to be detachably connected between each section.Being detachably connected can use flange connection, it would however also be possible to employ Clamp connection structure.Clamp connection structure is mounted in two sections of arc-shaped steel tube junctions, two cards using two relative hoop sleeves The relative both sides of hoop are each with 4 bolt connections, the sealing of two clip intermediate cryptographics or sealing gasket, prevent slurries from leaking.Junction Can not select at injection point and have at grouting port.
It is non-standard to strengthen slip casting steel pipe 4, and wall thickness 4-20mm is processed using the special curved equipment of type, it is special it is customized form, External diameter according to corrugated steel pipe 1 is processed.
Fig. 1,2 displays, multiple reinforcement slip casting steel pipe 4 are arranged in parallel along the length direction of corrugated steel pipe 1, adjacent to strengthen note Spacing between slurry steel pipe 4 is 1-1.5 meters.Each bottom for strengthening slip casting steel pipe 4 is evenly equipped with multiple slip casting apertures 5.Multiple adds The upper end of injection slurry steel pipe 4 is respectively mounted slip casting flange 7, and slip casting flange 7 is connected with bump joint 8, bump joint 8 and slip casting Conduit 9 is connected, and grouting pipe 9 is connected with slip casting machine 10.During slip casting, be input into for slip casting by grouting pipe 9 by slip casting machine 10 To in reinforcement slip casting steel pipe 4, the wedge-shaped position in the lower section of corrugated steel pipe 1 is injected into by the slip casting aperture 5 for strengthening the bottom of slip casting steel pipe 4 Backfill in, fill gap, to support corrugated steel pipe 1, prevent deformation.
Fig. 3 shows that reinforcement slip casting steel pipe 4 is arranged on the position of crest 2 of corrugated steel pipe 1.Because the position of crest 2 is to arch The curved surface for rising, the inner side tube wall circumference of the annular body of reinforcement slip casting steel pipe 4 with matching have circular body to pipe The recessed circular groove 17 in internal side, the circular arc degree of groove 17 matches with the circular arc of the crest 2 of corrugated steel pipe 1, groove 17 Outer surface be in close contact with the crest 2 of corrugated steel pipe 1.
Fig. 4 shows that reinforcement slip casting steel pipe 4 is arranged on the position of trough 3 of corrugated steel pipe 1, strengthens the annular of slip casting steel pipe 4 The inner side tube wall circumference of body has the arc-shaped convex 18 to body outside protrusion of circular body, raised 18 circular arc degree and steel The circular arc of the trough 3 of bellows 4 matches, and raised 18 outer surface is in close contact with the trough 3 of corrugated steel pipe 1.
Fig. 3,4 displays, are strengthened slip casting steel pipe 4 and are connected using connecting bolt 12 at crest 2 and trough 3 with corrugated steel pipe 1 Connect.Specific connected mode is that have multiple to be connected hole 11 on the inner side tube wall of annular body for strengthening slip casting steel pipe 4, Multiple is connected hole 11 along the circumference uniform distribution for strengthening slip casting steel pipe 4, and the spacing between the adjacent hole 11 that is connected is 400mm.There is corresponding bolt connecting hole 13 on the tube wall of corrugated steel pipe 1, connecting bolt 12 passes through be connected hole 11 and spiral shell Bolt connecting hole 13 is fixedly connected slip casting steel pipe 4 is strengthened with the tube wall of corrugated steel pipe 1.
Fig. 3,4 displays are because connecting bolt 12 is located at the intracavity bottom for strengthening slip casting steel pipe 4 therefore necessary when mounted Carried out by the tube wall for strengthening slip casting steel pipe 4, its method is, on the outside tube wall of annular body for strengthening slip casting steel pipe 4 Multiple fastener holes 14 are provided with, fastener hole 14 is located at the top in the hole 11 that is connected, fastener hole 14 and the phase one by one of hole 11 that is connected It is right.When installing connecting bolt 12, intermediate cryptographic packing ensures sealing, and box spanner 16 is extend into reinforcement slip casting from fastener hole 14 In steel pipe 4, nut is entangled in the front end of box spanner 16, the rear portion of rotational sleeve spanner 16 by nut, then from fastener hole Box spanner 16 is withdrawn from 14.There is connecting screw hole on the tube wall of the both sides of fastener hole 14, closure is used after tightening connecting bolt 12 15 are blocked fastener hole 14 by connecting screw hole.The structure of box spanner 16 is current techique, due to needing placement in sleeve The space of the front end screw rod of connecting bolt 12, therefore the inner chamber of sleeve needs lengthening, other structures are identical with general box spanner.
Application method of the invention is as follows:
(1)The grading ring for strengthening slip casting steel pipe 4 is attached after corrugated steel pipe 1, crest of the link position in corrugated steel pipe 1 2 or trough 3.When low load high, span and when disposal load is larger on highway, it is respectively mounted on each crest 2 or trough 3;Work as height Low load, span and when disposal load is general on highway, can be spaced apart.Such as without particular/special requirement, between reinforcement slip casting steel pipe 4 Spacing is 1-1.5 meters.
(2)The hole 11 that is connected for strengthening slip casting steel pipe 4 is relative with the bolt connecting hole 13 of corrugated steel pipe 1, and insertion connects Connecting bolt 12, intermediate cryptographic packing ensures sealing, and box spanner 16 is extend into reinforcement slip casting steel pipe 4 from fastener hole 14, turns Then the nut of connecting bolt 12 is withdrawn from box spanner 16 by the rear portion of moving sleeve spanner 16 from fastener hole 14, fastening Hole 14 is blocked with closure 15, makes reinforcement slip casting steel pipe 4 for closed body, is easy to injection slurry to be flowed from the slip casting aperture 5 of bottom To the uncompacted position filling gap in the bottom of corrugated steel pipe 1 wedge shape position.
(3)Strengthen adpting flange joint 8, bump joint 8 and the phase of grouting pipe 9 on the slip casting flange 7 of the upper end of slip casting steel pipe 4 Connection, grouting pipe 9 is connected with slip casting machine 10.Slurries are pressurizeed in slip casting machine 10, and reinforcement slip casting is injected into by grouting pipe 9 In steel pipe 4.When corrugated steel pipe 1 is backfilled to 2/3rds of height or so can initiation pressure slip casting, injection slurry flows to steel ripple The uncompacted position in the bottom of pipe 1 wedge shape position, fills gap, to support corrugated steel pipe 1, prevents deformation.
(4)Behind injection slurry wedge shape position whole full of the bottom of corrugated steel pipe 1, strengthen leaving slurries in slip casting steel pipe 4, coagulate Gu after also can as corrugated steel pipe 1 strengthen use.
