Survey port pipe flange bottom whether consistent with the distance four Mondays ring on steel cylinder surface）, then by pressing plate 4 along port pipe 2 one weeks
Point weld, by port diameter using 4-8 only, and pushed with the hold-down bolt 5 on pressing plate 4 port pipe 2 be pressed on into steel cylinder
On 18.
Note：（1）The decrement that the pressing plate 4 of 2 surrounding of port pipe compresses 2 surrounding of port pipe is consistent；（2）Sealing ring to be guaranteed
8 decrement is in 8-12mm, but unsuitable tension；（3）1-2 is put in space between 2 flange in the bottom 16 of port pipe and steel cylinder 18
Ring hydro-expansive rubber bar 9.（4）Cement mortar will be filled up in port pipe 2 and the space of PCCP steel cylinders 18, until with PCCP outside protect
Sheath is put down.（5）Reinforcing fagging 3 between welding port pipe 2 and upper anchor ear 6（At general welding 4-6）.6. by valve and port pipe
Flange connection on 2.
7. perforate operation as shown in Figure 7：Mechanical tapping equipment machine is put into into the valve of unlatching, will in the middle of port pipe 2
19 perforate of PCCP steel cylinders 18 and concrete tube core.
8. tapping equipment exits valve, and closes valve, and the hole to holding successfully carries out quality inspection.The method of inspection is to manage
Hydraulic pressure in line increases to the pipeline service pressure, checks whether osseotomy site has the situation of seepage, such as the perforate without if
Success.
Rubber mat plate 7 is set between upper anchor ear 6, lower anchor ear 13 and lined Prestressed concrete cylinder pipe 14, including
Perforate on lining formula Prestressed concrete cylinder pipe 14 employs clamped-in style anchor ear, solves due to perforate and has cut off prestressing force height
Make body bear intrinsic pressure and external load after strong steel wire 17, in anchor ear and the body of lined Prestressed concrete cylinder pipe 14
Between be lining into the thick rubber mat plates 7 of 10mm, solve anchor ear and lined Prestressed concrete cylinder pipe 14 external protection it
Between the stress concentration point that produces as external protection is uneven, rubber mat plate 7 can play a part of the diffusion of concentrated stress point.
Boring method in the present invention is only operated on existing pipeline, need not be retubed, be greatlyd save manpower and materials,
And can be with Operating Pressure, method is easy, effect is significant.
