Description
Technical field
The utility model relates to technical field of construction, relates in particular to a kind of Application of light well point precipitation pipe hole-forming device.
Background technology
At present, well-points dewatering pore-forming generally adopts impact type or rotary drill pore-forming.Impact type is to utilize high-pressure hydraulic pump, by flexible pipe, is connected with the steel pipe of a Gent system, and steel tube end part is provided with hole for water spraying, by two hand-held steel pipes of operator, in header position, twitched up and down, until pore-forming, depth of pore forming is generally dark than chimney filter, should be noted that jet water spout vertically inserts in water during punching, and swing up and down about doing, after pore-forming, to extract immediately jet water spout, insert downcomer, in order to avoid cave in, complicated operation, pore-forming is slow.And utilize the similar pile foundation construction of slewing drilling machine pore-forming, and needing mud pit or place, machinery requires relatively high.
Utility model content
The purpose of this utility model is to provide a kind of Application of light well point precipitation pipe hole-forming device, the problems referred to above that exist to solve prior art.
The purpose of this utility model is to be achieved through the following technical solutions:
An Application of light well point precipitation pipe hole-forming device, comprises downcomer and the hammering sinking device being used in conjunction with, and described downcomer top is provided with opening, and downcomer bottom is distributed with permeable hole, and downcomer bottom is blind end; Described hammering sinking device comprises hammer and air compressor, between air compressor and described hammer, is connected with pressure hose.
Further, described permeable hole is plum blossom-shaped distribution.
Further, the blind end of described downcomer bottom is conical.
Application of light well point precipitation pipe hole forming method comprises the following steps:
1) according to engine request, prepare downcomer;
2) utilize external force strong rammer downcomer to bury: to use air compressor as dynamic power machine, with hammer, downcomer is hammered in the soil body, between air compressor and hammer, by flexible pipe, be connected, hammer directly acts on downcomer, operating personnel's operation is on scaffold, and scaffold is selected door-type scaffold platform;
3) utilize water under high pressure to carry out well-flushing to downcomer: with flexible pipe, inserts in downcomer, utilize water under high pressure to pour into downcomer, and then groundwater abstraction is with the water outlet of tiny disturbed soil particle, repeatedly operation until the water yield evenly or go out clear water;
4) adopt rubber hose to be connected to house steward each downcomer, with vacuum pump, try to take out.
The beneficial effects of the utility model are: simple in structure, cheap, easy to use, become well rapid, being not easy to punching becomes well area also can use, utilize downcomer to be used as drinking-water pipe and the hole retaining wall that buries, a pipe is dual-purpose, and body meets the vacuum strength stability requirement of drawing water and bury.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of Application of light well point precipitation pipe hole-forming device described in the utility model embodiment.
In figure:
1, downcomer; 2, opening; 3, permeable hole; 4, hammer; 5, air compressor; 6, pressure hose; 7, door-type scaffold.
The specific embodiment
As shown in Figure 1, Application of light well point precipitation pipe hole-forming device described in the utility model embodiment, comprises downcomer 1 and the hammering sinking device being used in conjunction with, and described downcomer 1 top is provided with opening 2, downcomer 1 bottom is distributed with permeable hole 3, and downcomer 1 bottom is blind end; Described hammering sinking device comprises hammer 4 and air compressor 5, between air compressor 5 and described hammer 4, is connected with pressure hose 6; Described permeable hole 3 is plum blossom-shaped and distributes; It is conical that the blind end of described downcomer 1 bottom is.
Application of light well point precipitation pipe hole forming method described in the utility model embodiment, comprises the following steps:
1) according to engine request, prepare downcomer: be about 6m, diameter 48.3mm, wall thickness 3.5mm, is drilled with the permeable hole of spacing 100mm quincuncial arrangement in the 0.7m of bottom, and the taper shape of sealing is made in downcomer lower end.
2) use air compressor (75m3/min) as dynamic power machine, with special hammer, downcomer is hammered in the soil body, between air compressor and hammer, by diameter 50mm flexible pipe, be connected, hammer directly acts on downcomer, operating personnel's operation on scaffold, the protection of taking care during operation.
3) with the PVC flexible pipe of diameter 32 or 25, inserts in the welded steel pipe downcomer of being driven underground, utilize water under high pressure to pour into downcomer, and then groundwater abstraction is with the water outlet of tiny disturbed soil particle, repeatedly operation until the water yield evenly or go out clear water.
4) between downcomer and house steward, adopt L=1.2m, the rubber hose of Φ 40 connects, and tighten with iron wire at two, smears yellow mud outward, with anti-gas-leak, finally connects vacuum pump and try to take out.
Downcomer 1 adopts 6 meters of above welded steel pipes of left and right Φ 48.3 * 3.0mm wall thickness, is drilled with the steel pipe of permeable hole in the 0.7m of bottom, permeable hole spacing 100mm, and quincunx pore-forming, the taper shape that sealing is made in steel pipe lower end is convenient to hammer.Hammer 4 directly acts on downcomer 1, with the air compressor 5 compressed air impulse forces that adopt 75 to 150kw, be converted into the power that 1 hammering is sunk to downcomer, downcomer 1 use hammer 4 hammerings are buried, realization is suppressed downcomer and is buried and get rid of without mud, without big machinery, operate, use door-type scaffold 7 as the support that hammers of downcomer 1, the high about 5m of frame simultaneously.
Washing well process is because downcomer 1 hammering is buried in process, in downcomer 1, may have silt etc. and infiltrate inside, and the downcomer original soil layer construction balance of disturbance of burying in addition, unclear hole can affect later stage outlet effect.The sebific duct of diameter 30mm is inserted to downcomer 1 bottom and carry out water filling cleaning, until flow out clear water, should clean by root, avoid occurring " extremely pipe ".
When examination is taken out, the effect of vacuum pump is to provide negative pressure underground water in the soil body is retracted to earth's surface by downcomer 1, connecting hose, house steward, reach the effect of dewatering, the vacuum of general well point system should remain on 55.3 ~ 66.7kPa, pressure should remain on 0.16MPa, herein because vacuum pump provides vacuum ability reason, the general Application of light well point precipitation degree of depth only has 6 ~ 9m, cannot extract dark water out again.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
