Described manifold assemblies 15 comprises port pipe 2, be welded in the flange 1 of port pipe 2 upper ends and be welded in the flange in the bottom 16 of port pipe 2 lower ends, between port pipe 2 and flange in the bottom 16, be welded with the gusset 10 of reinforcement effect, between port pipe 2 and upper anchor ear 6, be welded with fagging 3, seal ring 8, hydro-expansive rubber bar 9 are arranged at described flange in the bottom 16 bottom surfaces.
Described pressing plate 4 has 6 ~ 8, and 6 ~ 8 block pressur plates are along the through hole circumference uniform distribution of upper anchor ear 6.
The step that use foregoing invention product carries out perforate operation is as follows:
One. first carry out by drawing accessory and the preparatory work such as relevant, specifically
1. (generally the size of perforate should be less than by 1/2nd of perforate PCCP pipe internal diameter first will to map out the size of perforate on lined Prestressed concrete cylinder pipe, the tubing bore size of example DN600 should be less than DN300, the tubing bore size of DN800 is just less than DN400), as shown in Figure 1.
2. first carry out by drawing the required accessory of perforate, as above anchor ear 6, lower anchor ear 13 and port pipe 2 etc., and the valve that buying is good and perforate mouth upper flange 1 is supporting.
3. be ready to the required auxiliary material of perforate, as seal ring 8, hydro-expansive rubber bar 9, rubber mat plate 7 etc.
4. before perforate, should be ready at the scene equipment and the related tools such as electric welding, gas cutting, mechanical tapping machine.
Two. perforate construction.
1. first will need the soil of lined Prestressed concrete cylinder pipe 14 peripheries of perforate to hollow out, requirement all hollows out and leaves manually-operated position at the position of perforate tube circumference and (notices that pipe bottom also will hollow out, anchor ear is conveniently installed), and the earth on pipe shaft is rinsed well.
2. select tapping point, pipeline tapping point is preferably chosen in and leaves the position that PCCP tube faucet, socket position are greater than 1.5 meters.
3. as shown in Figure 2, first upper anchor ear 6, lower anchor ear 13 are arranged on pipe shaft, the position of perforate on upper anchor ear 6 is placed on to pipe and needs on the position of perforate (generally in pipe bi-side) note below upper anchor ear 6, on above anchor ear 13, served as a contrast rubber mat plate 7, and tighten the anchor ear bolt 11 of upper and lower anchor ear both sides.
4. as shown in Figure 3,4,, along holding the position in hole on upper anchor ear 6 successfully, the rubber mat plate 7 by lining in 6 times faces of upper anchor ear prescinds, and removes mortar cover 20 and the hoop High Tensile Steel Wire 17 on PCCP body.
The place that this step should be noted that is: when (1) removes mortar cover 20, care should be used to clink soft peening, does not destroy protective layer and steel cylinder 18 outside hole; (2) cut off the High Tensile Steel Wire 17 in hole, but can't damage steel cylinder 18.
5. as shown in Figure 5, port pipe is installed: (1) is first bonded at the moderate seal ring 8 use glue of a ring 20mm diameter flange in the bottom 16 bottom surfaces (ring diameter of seal ring 8 should be greater than 6 centimeters of left and right of port pipe 2 diameter) of port pipe 2.
(2) cut-and-dried irony pressing plate 4 is welded on upper anchor ear 6,2 of first welding, as shown in Figure 6.
(3) port pipe 2 is arranged on PCCP steel cylinder 18, should notice that port pipe 2 is arranged on position on PCCP steel cylinder 18 (whether range estimation port pipe flange bottom is consistent with distance surrounding one ring on steel cylinder surface), then pressing plate 4 is divided equally and welded along port pipe for 2 one weeks, press port diameter and adopt 4-8 only, and press down port pipe 2 is pressed on steel cylinder 18 with the hold-down bolt 5 on pressing plate 4.
Attention: the decrement that the pressing plate 4 of (1) port pipe 2 surroundings compresses port pipe 2 surroundings is consistent; (2) decrement that will guarantee seal ring 8 is at 8-12mm, but unsuitable tension; (3) in the space between port pipe 2 flange in the bottom 16 and steel cylinder 18, put 1-2 ring hydro-expansive rubber bar 9.(4) will in the space of port pipe 2 and PCCP steel cylinder 18, fill up slush, until flat with PCCP external protection.(5) the reinforcing fagging 3(between welding port pipe 2 and upper anchor ear 6 generally welds 4-6 place).6. valve is connected with the flange on port pipe 2.
7. perforate operation as shown in Figure 7: mechanical tapping equipment machine is put into the valve of unlatching, along in the middle of port pipe 2 by PCCP steel cylinder 18 and 19 perforates of concrete tube core.
8. tapping equipment exits valve, and throttle down, and quality inspection is carried out in the hole of holding successfully.The method of check is that the hydraulic pressure in pipeline is increased to this pipeline normal operating pressure, checks whether perforate position has the situation of seepage, as not perforate success.
At upper anchor ear 6, between lower anchor ear 13 and lined Prestressed concrete cylinder pipe 14, rubber mat plate 7 is set, on lined Prestressed concrete cylinder pipe 14, perforate has adopted clamping type anchor ear, solved because perforate makes body cannot bear interior pressure and external load after having cut off Hight strength cable 17, between anchor ear and the body of lined Prestressed concrete cylinder pipe 14, be lining into the rubber mat plate 7 that 10mm is thick, solved between anchor ear and the external protection of lined Prestressed concrete cylinder pipe 14 due to the uneven stress concentration point producing of external protection, rubber mat plate 7 can play the effect of concentrated stress point diffusion.
Boring method in the utility model only operates on existing pipeline, without retubing, has greatly saved manpower and materials, and can Operating Pressure, and method is easy, effect is remarkable.
