Description

A kind of Whirlwind tank water-stop curtain
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
For solving the problems referred to above, the technical scheme that the present invention provides is:
A kind of Whirlwind tank water-stop curtain, including Whirlwind tank urceolus, support pile and water-seal pile, sets in the outside of Whirlwind tank urceolus Putting row's support pile, arrange water-seal pile in the outside of support pile, arrange water-seal pile between adjacent support pile, two contacted are only Overlap between water stake.
Preferably, support pile is cast-in-situ bored pile, uses drill hole of drilling machine, is transferred to by steel reinforcement cage in hole, joints cement.? In the work progress of fender pile, absolute altitude, mud balance, Underwater Concrete quality at the bottom of strict control stake position, stake pile jacking.
Preferably, weld one section of reinforcing bar in the inner side of support pile, be integrally formed for the outer tube wall with Whirlwind tank.
Preferably, the quantity arranging water-seal pile is more than two rows, is so to strengthen stagnant water effect, and water-seal pile also may be used To play the effect of opposing soil body lateral pressure.
Preferably, water-seal pile uses high-pressure rotary jet grouting pile, is affected by geological condition, prevents water from entering Whirlwind tank, the most also Can carry earth lateral pressure, there are not the quality problems such as infiltration drainage in Whirlwind tank urceolus;Traditional deep-mixed pile can not Going deep into soil layer too deep and can not tackle the shortcoming of complex situations in soil layer deep, cement mortar is sprayed into soil layer by the nozzle of high-pressure rotary Mixing with the soil body, form the cement stabilization body of lap connection, construction area is few, it is little to vibrate, noise is relatively low.
Preferably, spaced set support pile.Make Whirlwind tank outer tube wall, stress balance, stable gravity center.
The construction method of a kind of Whirlwind tank water-stop curtain, the steps include:
A, design overall scheme, according to Whirlwind tank size, calculate support pile and the quantity of water-seal pile and size;
B, at selected region excavation pit, the degree of depth of foundation ditch is 3-6m;Can reduce support pile stake long, reduction is constructed into This;
Domatic in C, foundation ditch using injection plain concrete mask, the gradient is 1:1, protects and domatic does not occur the soil body to glide, collapses Collapse;
D, build gutter by laying bricks or stones in the surrounding of foundation ditch, the hydrops in foundation ditch is transferred out, in order to construction;
E, making steel reinforcement cage, in foundation ditch, use cast-in-situ bored pile construction technology support pile;Can determine that Whirlwind tank is overall Construction size, shortens construction period, it is not necessary to destroy established facility parts, reduces construction cost;
F, the 2nd row's water-seal pile is set between adjacent support pile, the 1st row's water-seal pile is set in the outside of support pile, use Construction of High Pressure Jet Grouting Pile water-seal pile;Affected by geological condition, prevent water from entering Whirlwind tank, also be able to carry soil side pressure simultaneously Power.With the time interval in step E not less than 7 days, being fully cured between cement and the soil body of support pile, the cement of support pile is complete All solidstate, reduces the gap between the soil body, increases degree of compaction, reduces the gap between cement granules in support pile, prevents water saturating Cross the soil body and support pile enters in Whirlwind tank;
G, on the inner side campshed of support pile, weld one section of reinforcing bar, for being integrally formed with the pool wall of Whirlwind tank;Good Place is: 1) utilize support pile as the wall thickness of the pool wall of Whirlwind tank, cost-effective;2) support pile increases as the outer tube wall of Whirlwind tank Add the deadweight of Whirlwind tank, add anti-floating power.
Preferably, surrounding at the bottom of step B mesoslope top, slope arranges gutter or french drain, and surface water carries out organized bright row.
Preferably, in step A, the degree of depth of foundation ditch is 3-6m.
Preferably, the surrounding at foundation ditch is built erection PVC drain pipe by laying bricks or stones and is realized draining, forms drain line;Along four in foundation ditch Week excavates easy gutter and sump, uses sewage pump by the gutter of surrounding above the hydrops pump drainage in foundation ditch to foundation ditch In, enter sewerage system through three grades of sedimentation tanks.
3. beneficial effect
