In the pipeline dewatering construction, adopt artificial dewatering's method mostly, specifically have: the method for draining, tube well precipitation method, submersible pump pump drainage etc. is carried out in excavation open drain, operation band both sides, in practical project, often adopts methods such as light well point or eductor well point to carry out large-area precipitation.Project Headquarter of Baoshan Iron ﹠ Steel Works (Gen), Shanghai has applied for the patent of negative pressure of vacuum tube well dewatering, this negative pressure of vacuum tube well dewatering device is on existing tube well dewatering basis, increased the negative pressure of vacuum polywater device that a cover is made up of tube well dewatering and negative pressure of vacuum system, it is fast to make it reach dewatering effect, and No.5 Engineering Corp., Baogang Metallurgical Construction Corp., Shanghai has applied for the patent of well micro point dewatering device, this miniature precipitation well point device is with original huge light well point device microminiaturization, promptly adopt miniature well point pump machine system and miniature pipe-line system, and used a kind of filter that has sand filter blanket, make it be more suitable for the particularly dewatering project of local deep foundation ditch construction under particular surroundings.No.3 Construction Co., SINOPEC has used the light well point dewatering process in the water network zone long distance pipeline work progress of the south of the River, this technology is to cause certain vacuum by vacuum pump, make the underground water potential energy continuously guide ground through well point pipe and charge for remittance house steward, and be discharged into beyond the works area, form a precipitation funnel around making every well point pipe, can cause the decline in blocks of former underground water level, the arrangement form that this light well point dewatering process is commonly used has: single well-points dewatering, double well-points dewatering, the well-points dewatering of " U " shape, rectangle, method for arranging such as polygonal sealing layout.
Summary of the invention
The purpose of this utility model provides a kind of sealing multitube stratum precipitation device, it can effectively solve in pipe works construction construction to the stratum water level high and cause as pipe canal digging be difficult to be shaped, connect under the ditch that head can't be constructed, push pipe passes through the operation hole and problem such as can't build, and makes the practical difficulty of construction environment that good improvement arranged.
The purpose of this utility model is to realize like this, design a kind of sealing multitube stratum precipitation device, which comprises at least chimney filter 1, well point pipe 2, centrifugal pump 4, motor 5, header 3, water collector 7 and pipeline, it is characterized in that: chimney filter 1 is fixed on underground, between chimney filter 1 and the chimney filter 1 distance is arranged, each chimney filter 1 is connected with header 3 pipes by well point pipe 2 respectively, and header 3 is communicated with centrifugal pump 4, and centrifugal pump 4 outlets are communicated with water collector 7 by gutter 6; Centrifugal pump 4 connects motor 5.
Described header 3 is selected the long steel pipe of 1500mm of Φ 89 for use, and the hole of Φ 38 is arranged perpendicular to the pipe center line every 20mm.
Described header 3 has the hole of 14 Φ 38.
Described water collector 7 is escape canals.
The utility model has the advantages that:
A, this method use in different geological conditions and different groundwater table and have all obtained good effect.Can select what of pump group according to groundwater table height, flow size, the density Cheng Du of suction pipe, arrangement mode and combination and suit measures to local conditions.
B, this method can reduce because of stratum drawdown flow when precipitation.
If C is in normally drawing water, pump not water outlet suddenly can have or not breakage by the scrutiny suction pipe, and solder joint, joint have or not the gas leakage situation, after solving then again exhaust draw water.
D, this covering device cost are low, and between the every cover cost 500-600 unit, but various places price difference can be grasped flexibly.
E, this method are easy to learn, easy to operate, applied range, and promotion prospect is fine.
Description of drawings
Below in conjunction with the embodiment accompanying drawing the utility model is described further.
Fig. 1 is the utility model example structure schematic diagram.
Among the figure: 1, chimney filter; 2, well point pipe; 3, header; 4, centrifugal pump; 5, motor; 6, gutter; 7, water trap.
The specific embodiment
As shown in Figure 1, at least comprise chimney filter 1, well point pipe 2, centrifugal pump 4, motor 5, header 3, water collector 7 and pipeline, chimney filter 1 is fixed on underground, between chimney filter 1 and the chimney filter 1 distance is arranged, each chimney filter 1 is connected with header 3 pipes by well point pipe 2 respectively, header 3 is communicated with centrifugal pump 4, and centrifugal pump 4 outlets are communicated with water collector 7 by gutter 6; Centrifugal pump 4 connects motor 5.Described water collector 7 is escape canals.
Header 3 is selected the long steel pipe of 1500mm of Φ 89 for use, cuts a hole perpendicular to the Φ 38 of pipe center line, totally 14 every 20mm with oxygen.The joint of header 3 and suction water pipe is selected the steel pipe of Φ 38 for use, the long 10mm of each joint, and totally 14, joint and header 3 adopt and are welded to connect.3 one of Φ 89 headers are blocked the flange that burn-on in the other end and pump inlet is complementary with blind plate.
During work, the air of centrifugal pump 4 and the pipe-line system of draining, make centrifugal pump 4 and pipe-line system form certain vacuum, actuating motor 5 drives centrifugal pump 4, and this moment, underground water entered pipe-line system by chimney filter 1, be pooled to header 3 by well point pipe 2, enter centrifugal pump 4,, water is discharged to escape canal through gutter 6.
