Embodiment
Adopt the utility model to repair Prestressed concrete cylinder pipe, first clear up the earthing at pipeline top, excavate out working surface.Adopt welding gun or blowtorch to be dried by the tube wall around the mouth of pipe, clear up surperficial surface dust.Carry out repairing of getting into the cave after cleaning out, repair organigram and see Fig. 1, concrete operation step is as follows.
1) to the concrete reaming outside steel cylinder.Adopt electric hammer or drill rod that damaged hole is expanded every side 10 ~ 20mm, see Fig. 2, Fig. 3, the dotted line in figure is damaged inwall 15, expand to reaming inwall 16, counterbore depth is to steel cylinder 11 place, and the position of fracture of wire 6 can be expanded a bit more, expand steel wire draw-in groove 17, be beneficial to steel wire card 8 is installed.Should note not damaging not disconnected steel wire 13 during reaming.
2) supporting plate 1 is installed.Adopt the corrosion resistant plate of thick 3mm to make a supporting plate 1, supporting plate 1 width is slightly less than damaged diameter, and length is greater than damaged diameter about 20mm.Supporting plate 1 welds a U-shaped card, pull bar 2 installed by card, pull bar 2 is formed hinged with holder 1 plate, and pull bar 2 can rotate on supporting plate 1, and the top of pull bar 2 is provided with screw thread.Supporting plate 1 pads one block of rubber plate, and rubber plate is slightly wider than damaged diameter.Erected by supporting plate 1 and insert in damaged hole, then mention pull bar 2, supporting plate 1 and rubber plate are stuck on the inwall of pipeline lining 10 of pipeline.Adopt thick 2 ~ 3mm steel plate, make the shrouding 4 of a size 5 ~ 10mm larger than the every side of steel cylinder 11 breakage spot of Prestressed concrete cylinder pipe, shrouding 4 is processed into the arc (with reference to pipe outer wall) consistent with the steel cylinder 11 of Prestressed concrete cylinder pipe, bore an aperture slightly larger than pull bar 2 diameter in the middle of shrouding 4, pull bar 2 can pass aperture.Be enclosed within by the aperture of shrouding 4 on pull bar 2, the door frame 18 that an angle steel is welded is placed at pipeline outer wall place, and pull bar 2 adopts screw 19 to be fixed on door frame 18, and shrouding 4 is suspended on the top of pull bar 2, sees Fig. 4.
3) interior repair layer is filled.In the hole expanded, adopt repair layer 3 in rapid hardening cement filling, be filled to steel cylinder 11 place, steel cylinder 11 must not be exceeded, in order to avoid impact welding shrouding 4.Fast hard mortar can solidify at 5 ~ 10min, can greatly shorten the time of carrying out next process.Fast hard mortar with the addition of cement hardener in slush, the ratio 1:1 of cement and sand, and cement hardener doping level accounts for cement consumption 2% ~ 3% in mortar, and preparing fast hardening mortar and service speed want fast, complete, see Fig. 5 before initial set.
4) shrouding is welded.After the fast hard mortar of interior repair layer 3 solidifies, unclamp the screw 19 of the pull bar 2 on door frame 18, remove door frame 18, shrouding 4 is fallen to steel cylinder 11 place, adjustment shrouding 4 and the arc anastomosis of steel cylinder 11, weld the aperture of pull bar 2 with shrouding 4, the pull bar 2 on excision top, then shrouding 4 is welded with steel cylinder 11.Because steel cylinder 11 thickness is only 1.5mm, small area analysis should be adopted when shrouding 4 welds with steel cylinder 11 to weld, avoid burn-through steel cylinder 11, see Fig. 6.
5) steel wire and steel wire stretching is connected.Adopting the High Tensile Steel Wire of same size to intercept suitable length to make and connect silk 7, for connecting cut-off fracture of wire 6, connecing the top that silk 7 is placed in fracture of wire 6, adopt steel wire card 8 by fracture of wire 6 and connect silk 7 and fix, everywhere fracture of wire 6 with connect silk 7 and be connected employing two steel wire cards 8.First the fracture of wire 6 of both sides is connected, reserve a middle fracture of wire 6 and do not connect, carry out stress reinforcement for reinforcement wire stretch-draw.The steel pipe of diameter 100mm is adopted to do reaction frame, the middle reserved fracture of wire 6 one do not connect is connected with the longer silk 7 that connects, the longer the other end connecing silk 7 is fixed on one end of reaction frame, the other end of fracture of wire 6 adopts the tightener chuck of 5 tons to clamp, the other end of tightener connects the other end that a proving ring is fixed on reaction frame, shake tightener handle is to steel wire stress application, and tension stress controls to be advisable at 30kN, maintains the stretching force of 10min.By fracture of wire 6 with connect silk 7 and fix, redundance cuts off.Connect a sectional view and see Fig. 7, connect a planimetric map and see Fig. 8.
6) outer repair layer and sealing is filled.Shrouding 4 adopts epoxy resin mortar to fill outer repair layer 5 with upper part, and epoxy resin mortar has quick solidifying, intensity is high, ungauged regions, with concrete in conjunction with the feature such as firm, the compressive strength of 1 day can reach more than 50Mpa.Epoxy resin adopts 6101 types, ethylenediamine makes curing agent, dibutyl phthalate makes plasticizing agent, admixture acetone makes thinner, mixing ratio is: epoxy resin 100 parts, ethylenediamine 6 ~ 8 parts (determining according to temperature and curing time), dibutyl ester 15 parts, 20 parts, acetone, abundant mediation evenly finally adds ethylenediamine, first makes epoxy resin glue, then add cement 300 parts, dry sand 300 parts makes mortar.Control the addition content of curing agent during operation, filling should be completed before starting solidification.First adopt pressurized air by scum silica frost blowout in damaged hole, epoxy resin glue surface smear of getting into the cave is dipped in even with fine, soft fur pen, outer repair layer 6 is formed again to filling epoxy resin mortar in damaged hole, filled with mortar exceeds pipeline outer wall 10 ~ 20mm, form sealing 9, fracture of wire 6, connect silk 7 and steel wire card 8 is enclosed in sealing 9, see Fig. 1.
Water flowing is got final product after epoxy resin mortar solidifies completely.
