Description
Technical field
The utility model relates to a kind of Metro Deep Excavation dewatering well Accrete clearing device.
Background technology
In some sense, successful foundation pit dewatering is equal to foundation pit construction and hits half, especially rich water open cut deep foundation ditch.Subway open cut deep foundation pit precipitation usually adopt hole in dewatering well water-pumping/draining scheme, due to a variety of causes, dewatering well soil excavation construction in very easily by silting, landfill; In the case, traditional conventional treatment mode adopts artificial lower cleaning in well, and because hole diameter is little, this method efficiency is extremely low, cost is high, labour intensity is large, and the cleaning degree of depth is little, security risk very big, and after cleaning, dewatering effect is not good.
Utility model content
Its object of the utility model is just to provide a kind of Metro Deep Excavation dewatering well Accrete clearing device, solve that dewatering well labor cleaning labour intensity is large, efficiency is low, security risk is large, the problem of weak effect, have that cost is low, labour intensity is little, flexible operation, safety, efficiently feature, can be used for the desilting of the situations such as mud, soil, sandy gravel (within diameter 30mm).
Realize above-mentioned purpose and the technical scheme taked, comprise deep foundation pit precipitation well, in described deep foundation pit precipitation well, residue outlet and high-pressure air pipe are installed, high-pressure air pipe one end connects air compressor machine, and one end connects residue outlet through " U " shape gas outlet bend pipe, and described deep foundation pit precipitation well side is excavation face, opposite side is provided with well-flushing circulation puddle, side, well-flushing circulation puddle is provided with ditch, and ditch delivery port connects deep foundation pit precipitation well, and described residue outlet outlet is towards side, well-flushing circulation puddle.
Compared with prior art the utility model has the following advantages.
(1) can labor expenses be saved, reduce costs;
(2) innovate method for cleaning, reduce labour intensity;
(3) assembling of this device is simple, and flexible operation, easily grasps;
(4) security risk is low;
(5) clear up the degree of depth dark, speed is fast, effective, and the cleaning degree of depth rises to 6.5m/4h by artificial 1.5m/d, and the maximum degree of depth of once clearing up can reach 9m;
(6) applied widely, can be used for the situations such as mud, soil, sandy gravel (within diameter 30mm).
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is this apparatus structure schematic diagram;
Fig. 2 is bend pipe structure schematic diagram in gas outlet in this device.
Detailed description of the invention
Comprise deep foundation pit precipitation well 9, as shown in Figure 1, install residue outlet 4 and high-pressure air pipe 5 in described deep foundation pit precipitation well 9, high-pressure air pipe 5 one end connects air compressor machine 7, and one end connects residue outlet 4 through " U " shape gas outlet bend pipe 8, as shown in Figure 2, described deep foundation pit precipitation well 9 side is excavation face 6, and opposite side is provided with well-flushing circulation puddle 1, and side, well-flushing circulation puddle 1 is provided with ditch 2, ditch 2 delivery port connects deep foundation pit precipitation well 9, and described residue outlet 4 exports towards side, well-flushing circulation puddle 1.
Described residue outlet 4 is pvc pipe, diameter 63mm, and high-pressure air pipe 5 is high-pressure rubber hose, diameter 20mm, and gas outlet bend pipe 8 is steel pipe, diameter 20mm; High-pressure air pipe (5) lower end and gas outlet bend pipe 8 are tightly connected, and high-pressure air pipe 5, gas outlet bend pipe 8 hypomere 50cm colligation are at residue outlet 4 lower end outside.
Cofferdam 3 is provided with around described deep foundation pit precipitation well 9.
Embodiment
The operating principle of this device is, water is filled in dewatering well, in well, deposit (earth, sand, minor diameter cobble etc.) is disintegrated as little bulk after fully being infiltrated, after being broken up further by gases at high pressure, in well, mud mixture is lifted by gases at high pressure and is cheated to well outer circulation water storage along row of conduits, and water is after precipitation circulated in well again, so repeatedly, continuous displacement, reaches and removes deposit object in well.
Give vent to anger tube head and air compressor machine high-pressure air pipe of utilization is tightly connected firmly, jointly forms high pressure gas pipe-line system together with air compressor machine; Utilize that pvc pipe saves, complementary connector (straight joint, 90 degree of bent subs) is connected to form pipe-line system of slagging tap.This two system is linked together, constitutes well washing apparatus.During cleaning, in well, fill water, after artificial downward putting device, constantly move its position, utilize gases at high pressure that the sand of alluvial in well, earth, finger stone are thrown into residue outlet, drain into well outer circulation water storage hole after breaking up.Water is after precipitation circulated in well again, repeatedly replaces, and reaches cleaning object.When deposit hardens serious in dewatering well, be aided with water under high pressure simultaneously and coordinate.
Utilize 20mm × 2mm steel tube bending to become gas outlet bend pipe 8, be tightly connected firmly with air compressor machine high-pressure air pipe 5, jointly form high pressure gas pipe-line system together with air compressor machine; Utilize that 63mm × 3mm pvc pipe saves, complementary connector (straight joint, 90 degree of bent subs) is connected to form residue outlet 4 system, by high-pressure air pipe 5, the 50cm colligation of gas outlet bend pipe 8 lower end at residue outlet 4 lower end outside, constitute well washing apparatus, as shown in Figure 1.During cleaning, first well head knitting bagged fortifield village is protected, water is filled in well, manually transfer well washing apparatus, continuous shift position, utilize gases at high pressure that the sand of alluvial in well, earth, finger stone are thrown into residue outlet, enter the outer well-flushing circulation water storage hole of well after breaking up, circulation water storage hole capacity is no less than 4m
3.
When deposit hardens serious in dewatering well, be aided with water under high pressure simultaneously and break up, more convenient, fast clear up.Air pressure, hydraulic pressure pressure general control are at 0.2 ~ 0.4 MPa.
Material and equipment:
1.5 meters long 63mm × 3mm pvc pipes save 5, supporting straight coupling 4,90 degree of bent subs 1,20mm × 2mm special steel pipe bend pipe 1 (long 400mm), 7.5m
3air compressor machine 1, supporting tracheae 60m.
