Stop between nut and the stop grouting plug at stop grouting plug to be provided with packing ring, between stop grouting plug and push pipe, be provided with another packing ring, on described excessive slurry hole, be pasted with circular patch.
The utility model is simple in structure, and is easy to maintenance, can effectively reduce the slurries outflow during slip casting in the tunnel, the safety that has improved tunnel excavation.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Specific embodiment
A kind of Grouting Pipe, comprise slip casting body 2, slip casting core pipe 5, push pipe 4 and stop grouting plug 10, the head of described slip casting body 2 is the tapered tube head 1 of a closed hollow, slip casting body 2 is provided with the slurry hole 3 of overflowing, the core tube wall of the front end of slip casting core pipe 5 is provided with slip casting core pipe front end screw thread 6, the core tube wall of the rear end of slip casting core pipe 5 is provided with slip casting core pipe rear end screw thread 8, slip casting core pipe front end screw thread 6 is provided with stop grouting plug and stops nut 7, slip casting core pipe rear end screw thread 8 is provided with push rod nut 9, stop at stop grouting plug on the outer wall of the slip casting core pipe 5 between nut 7 and the push rod nut 9 to be disposed with stop grouting plug 10 and push pipe 4, the slip casting core pipe 5 that is with stop grouting plug 10 and push pipe 4 is movably arranged in the slip casting body 2.
Stop between nut 7 and the stop grouting plug 10 at stop grouting plug to be provided with packing ring 11, between stop grouting plug 10 and push pipe 4, be provided with another packing ring 12, on described excessive slurry hole 3, be pasted with circular patch.
The processing of Grouting Pipe is finished by following steps: adopt the long welded steel pipe of Profile cut-off machine cutting 4m; It is lobate to adopt autogenous cutting machine that the welded steel pipe front end is slit into three hemp nettles, with iron hammer the lobate steel disc of three hemp nettles is struck to the steel pipe axis direction and holds together into the pointed cone type, with electric welding welding pointed cone position, makes its seal good, promptly is processed into tapered tube head 1.Add weldering 6～8mm reinforcing bar at slip casting body end and make pipe collar.At Grouting Pipe week body, perpendicular separation 10cm is drilled with the excessive slurry hole 3 of 4.5mm with bench drill.Adopt the 10mm punching pin, on thin aluminum sheet, go out 10mm circle paster.Sticking with glue agent will justify paster and stick in the stepped ramp type boring.Grouting Pipe is placed 24h after sticking paster, treats can use after bonding adhesive has stronger adhesive strength.
Push pipe 4 adopts external diameter 32mm, and wall thickness 3.5mm, the seamless steel pipe of long 2.7m are as push pipe, and it mainly plays and promotes the stop grouting plug expansion, makes stop grouting plug play only slurry effect.Slip casting core pipe 5 adopts external diameter 20mm, wall thickness 4mm, the seamless steel pipe processing of long 3m.Front end processing 3～5cm male thread of slip casting core pipe 5, preparation bolt and pad play the stop grouting plug effect that stops; The rear end processing 20cm male thread of slip casting core pipe 5 is used for moving of push rod nut 9, and connecting line.The main effect of slip casting core pipe 5 is to carry slurries.Push rod nut 9 adopts external diameter 32mm, wall thickness 3.5mm, and the seamless steel pipe processing of long 30mm mainly expands stop grouting plug 10 by rotation push rod nut 9, plays only slurry effect.Stop grouting plug 10 adopts that good springiness, restoring force are strong, the top-quality rubber of good endurance, resistance to acids and bases.Processing dimension is external diameter 34mm, wall thickness 7mm, long 80mm.
When Grouting Pipe is used, adopt the two fluid grouting pump, take retrusive segmenting slip casting technology to carry out the slip casting operation.Retrusive segmenting slip casting technology: the slip casting core pipe that will have a stop grouting plug be inserted into the Grouting Pipe relevant position after push pipe is connected, the push rod nut 9 that turns clockwise expands stop grouting plug 10, only starches effect to reach.Connect grouting pipeline, adopt the slip casting in the hole of two fluid grouting pump, each slip casting segment length is chosen as 0.6m, after promptly first section slip casting was finished, inhour rotation push rod nut 9 made stop grouting plug return to original state, slip casting core pipe is retreated 0.6m, carry out second section slip casting, so go down, until whole slip casting section is finished.The retrusive segmenting slip casting will be paid special attention to the damaged condition of stop grouting plug 10, if find stop grouting plug 10 existing problems, should change immediately in the work progress, stops up in order to avoid cause Grouting Pipe, causes slip casting core pipe 5 to extract, and influences normal construction.
