Description
Technical field
The present invention relates to the construction field in circular cyclone pond, underground, particularly relate to a kind of Whirlwind tank water-stop curtain.
Background technology
Whirlwind tank is the production line auxiliary systems of requisite public affairs such as metallurgy industry steel-making, steel rolling, and it is to store and locate
The structures of the water that process equipment is cooled down by reason.It utilizes turbid circulating water that process equipment carries out water-spraying control, turbid circulation
Water first focuses in sluice, then concentration pours in Whirlwind tank, utilizes the impact eddy flow of water, by impurity and fosterization in Whirlwind tank
Iron sheets etc. produce precipitation to carry out concentrating crawl to utilize, so that turbid circulating water is recycled after precipitating and filtering.
Typically in half rock-soil layer (upper strata is soil, and lower floor is rock) construction Large Underground circular cyclone pond, can use underground even
Continuous wall or campshed supporting.But be difficult to enter construction, for soil layer relatively hard place than narrow regional main equipment for place
District's pile driving process difficulty inefficiency can improve construction cost.For large-scale Whirlwind tank, traditional means of defence quantities is big,
Construction cost is high, long construction period.
Chinese invention patent, Authorization Notice No. CN 102002952 B, authorized announcement date 2012.07.04, disclose one
Tu Yan combines the Whirlwind tank protection construction method of region, and it includes: step one, upper bore bored concrete pile around foundation ditch；Step
Two, earth excavation, and use close mesh expanded metal lath carry out overall covering and anchor between bored concrete pile going along with sb. to guard him；Step 3, outside foundation ditch
Hydrops is got rid of, and utilizes the drainage of close mesh expanded metal lath aqueous in the soil body, rock crack water to be dropped with rainy season with the effect of closure earth
Water introduces in foundation ditch, then gets rid of；Step 4, foundation ditch inner ring beam is constructed；Use one cap to add three road annular girders to collectively constitute
Supporting construction；Step 5, earth excavation, rock stratum explosion, drain the water away, rock crack water；Step 6, removes rubble after explosion,
After dirt, construct.Its weak point is: this invention uses close mesh expanded metal lath, this high to steel plate requirement performance requirement, and
Do not have waterproof effect, only Tu Yan is combined, or the comparison of clean rock geology is suitable for, if soil property is aqueous more, will not
Suitably, reason is, too much water can penetrate into the outside of Whirlwind tank outer tube wall, and it, affect the performance of Whirlwind tank for a long time.
Summary of the invention
1. invention to solve the technical problem that
For the problem of the waterproof anti-pressure differential of supporting of the Whirlwind tank of prior art, only the invention provides a kind of Whirlwind tank
Water curtain.It can pressure waterproof, anti-, and easy construction.
2. technical scheme
