Description
Technical field
Pipeline and auxiliary construction construction work field are the utility model is related to, more particularly to split is used in a kind of inspection shaft
Formula pipe plugging system.
Background technology
Current municipal pipeline from outside factory enters first large-scale pool structure in factory in water factory, typically passes through large-diameter pipe
Road and auxiliary construction (such as inspection shaft, gate valve well) carry out UNICOM.Built by separate periods engineering or reconstruction and extension project, easily occur due to
Former engineering design does not take into full account later reorganization and expansion, causes the inlet channel of preliminary engineering to be located at the construction use of reconstruction and extension project
In ground, and as the obstacle of reconstruction and extension project construction, it need to carry out changing and move water route and carry out former waterway pipe and auxiliary construction
Remove.
After the old pipeline that need to be cut off is cut off, the situation that old pipeline water route is run parallel with new pipeline water route is formed, will be old
Pipeline opening of the pipeline in UNICOM's inspection shaft is blocked to block raw water road, and then will leave water in old pipeline and adjunct
After pump drainage, old pipeline and auxiliary construction are removed.
At present, for the plugging construction operation at such a well indoor pipe road junction, general construction method is that application is cut off the water window, from
Water inlet source cuts off the water, and then robs work in the window phase inner tissue that cuts off the water, the water pump drainage that will be left as early as possible in pipeline and auxiliary construction,
The pipeline opening closure operation of raw water road pipeline, row water flowing again after the completion of closure are carried out after formation water-less environment.The construction method lacks
Fall into as follows：1. having to that application cuts off the water could organizing construction；2. former operation of engineering projects can be caused to stop during cutting off the water, cause huge
Operating loss and indirect loss；3. window phase typical time of cutting off the water is compressed extremely short, to ensureing that construction safety and quality are unfavorable.
Blocked for the well indoor pipe road junction under the conditions of water flowing, special circumstances need to use frogman to carry out underwater operation, the party
Method needs special operation workers and special equipment, and cost is high, and construction operation is dangerous big, and need to ensure underwater visual condition and welding
Condition.For the sewage of muddiness, or when pipe material does not possess welding condition, can not use.
Therefore study a kind of easy, quick, economic, safety pipeline opening closure solved with split type gate member it is above-mentioned
Defect present in construction method.
