Bolt and mating nut need 1200 sets, and totle drilling cost=150 pair * 2*100+1200 covers * 15=48000 yuan；New paragon: totle drilling cost=10*
1500(ball valve price)+800 meters * 30 yuan/meters=39000 yuan；And new paragon pipeline construction reduces flanged joint, welding and peace
Dress up this attenuating；Because the cushion that flanged joint uses due to pumping when pressure it is very big, be often easy it is bad, therefore reduce flange use
Amount can be such that late maintenance cost reduces.Conveying in feeding pipe is concrete, when flowing at elevated pressures, can be caused to tube wall
Certain abrasion, and pipe bent position abrasion is more serious, pipe bent position still takes flanged joint in new paragon, facilitates later period opposite grinding

For operation ball valve can, all ball valves are changed to electronic, pneumatic operated valve, then the labor intensity of worker can further drop
Low, working efficiency also greatly improves, and reduces the time used in unclog the pipe.
3. concrete can be all of not will cause waste: whether when unclog the pipe, or when normal filling is rinsed,
Concrete in all pipelines can be charged mineral building, not will cause the waste of resource, while entering the concrete of emergency lagoon
It reduces, the pressure of environmental protection can also be mitigated.
4. final step is to squeeze into pressure tailing normally in filling step, with the concrete in pressure tailing ramjet duct to mine
Room is then pumped into water, by pressure tailing and concrete pumping to work surface, monitors in pipe outlet, when water reaches work surface, stops
Only industrial pump closes gate valve at work surface, opens simultaneously gate valve at emergency lagoon, and open flush water pump, opens and rinses water route
1# ball valve is rinsed entire pipeline, and the sewage of flushing flows into emergency lagoon rather than flows into mineral building, can avoid water to concrete
Wash away, thus avoid filling concrete required intensity is not achieved.
