Description
Technical field
The present invention relates to buoyancy fields of measurement in glass reinforced plastic pipe mud mixture, in particular to glass in a kind of sink
Glass steel pipe uplift pressure measuring device.
Background technology
According to traditional mentality of designing, in strand thermal power plant, once-through cooling water takes, in drainage system, and Normal practice is
Use precast concrete pipe culvert or steel pipe as water intake conduit.During operation, it was also found that concrete pipe culvert exist from it is great, hang
The high problem of difficulty is filled, needs Large-scale Hoisting ship and dedicated construction harbour, and to more demanding, the project cost of sea base processing
It is very high；And although steel pipe avoids the above problem, but the corrosion resistance of steel pipe in the seawater is poor, anti-corrosion expense and operation
Maintenance cost is very high.It proposed in recent years and Successful utilization glass reinforced plastic pipe new departure in some Binhai Generator Stations, glass reinforced plastic pipe both may be used
Avoid due to from the high problem for causing difficulty of construction big of great, hoisting difficulty, also avoid steel pipe due to anti-corrosion cause engineering at
Sheet and the high problem of operation and maintenance cost；Meanwhile glass reinforced plastic pipe construction is simple, it can greatly shorten project duration, to effectively protect
The smooth implementation of power plant project water intake engineering is demonstrate,proved, there is extraordinary promotional value.Glass reinforced plastic pipe takes as a kind of novel
Drainage system material, a little with technologies such as light-weight, corrosion-resistant, anti-sea organism attachment, small, the service life length of frictional resistance.It can
Suitable for different types of acid, alkali, salt and a variety of oils, seawater and organic solvent.It is not required to cathodic protection protection and other anti-corrosions
Measure will not generate secondary pollution to water and other media.Its weight only has the 1/4 of steel pipe or ductile iron pipe, only cement
The 1/10 of pipeline.These advantages promote glass reinforced plastic pipe to be applied in more and more seawater taking and discharging projects.
When glass reinforced plastic pipe is applied in silt coast, geological conditions is relatively poor.Glass reinforced plastic pipe work progress needs
Burial protection is carried out to drainpipe.Especially offshore construction when, glass reinforced plastic pipe be laid with after backfilling process in, due to bury fiberglass
Water body silt content is very big in pipe foundation trench, and the density of mud mixture is close to 1.3t/m3.And the density after glass reinforced plastic pipe water filling and sea
Water is close, so glass reinforced plastic pipe at this time may deviate installation site under the buoyancy of mud mixture, is brought to construction
Risk, while also affecting the stability of glass reinforced plastic pipe.Pile may be used and glass reinforced plastic pipe is fixed in pipe collar, pipe collar
Pulling force to the principal element of structural strength.
In addition, construction after the completion of, glass reinforced plastic pipe in addition to bear protection layer soil body and upper water column static pressure other than, also by
The cyclic load of wave.Especially in typhoon storm wave season, cycle Wave Load may cause sea bed to liquefy, influence
To the stability of glass reinforced plastic pipe.In addition, the wave load being transmitted at glass reinforced plastic pipe may also influence the intensity of glass reinforced plastic pipe
And stability.Therefore it needs to test by water trough model and carries out research and analysis, it is ensured that the stability and safety of glass reinforced plastic pipe.
