Description
Technical field
The utility model relates to a kind of dredger, and especially a kind of dewatering well dredger, belongs to technical field of building construction.
Background technology
Job site, due in earthwork construction process, is not effectively protected or is protected facility to damage the earth, the sand etc. that cause and fall in dewatering well to dewatering well, cause dewatering well to stop up, and cannot carry out dewatering construction.For the processing of this type of dewatering well common fault, conventionally, near this obstruction dewatering well, again augment the processing method of dewatering well.The method not only cost is high, long in time limit and plant machinery and personnel demand larger, and affect the promptness of the precipitation in work progress; Sometimes augment dewatering well because scene affects, do not satisfy the requirements and cannot augment, affect precipitation operation.These all can produce certain impact to earthwork construction progress, difficulty.
Utility model content
The technical problems to be solved in the utility model is the defect existing for prior art, proposes a kind of dewatering well dredger, quickness and high efficiency ground dredging more, cleaning dewatering well.
The utility model is technical solution problem by the following technical programs: a kind of dewatering well dredger, comprise deep well submerged pump, its improvements are: the bottom of described deep well submerged pump connects sandstone filter through fixture, the bottom of described sandstone filter connects chimney filter by water under high pressure conversion head, the side of described water under high pressure conversion head is communicated with high-pressure water pipe, and the entrance of described high-pressure water pipe is provided with booster pump.
Described fixture is fixed on the bottom of deep well submerged pump by iron wire, make fixation.
Described sandstone filter is cylindric, and its diameter is identical with deep well submerged pump diameter, and the uniform filter bores of described periphery, to filter slime water.
The height of described high-pressure water pipe exceeds the upper end of deep well submerged pump, and described deep well submerged pump is fixed high-pressure water pipe by iron wire.
The upper end stationary rope of described deep well submerged pump, to put into whole device the dewatering well of obstruction.
When work, sandstone filter is fixed on to deep well submerged pump end with iron wire, after high-pressure water pipe and deep well submerged pump adopt iron wire to fix reliably, uses the rope being fixed on deep well submerged pump this dredger to be put into the dewatering well of obstruction.When dredging, first the backwash booster pump of high-pressure water pipe entrance is opened, utilize the impact force of hydraulic giant to rush falling into the earth, the sandstone etc. that cause well to stop up in dewatering well, the impact type backwash chimney filter that simultaneously utilizes high-pressure water pipe, impacts, rinses what plug silt, further makes silt rush.What plug silt is after impacting, rinsing, become slime water, slime water passes through sandrock filter, sandstone is filtered in sandrock filter, high-pressure water pipe is opened and is rinsed after approximately 3 minutes, opens deep well submerged pump and carries out extracting of slime water, every about 15 minutes, this device is taken out sandstone filter is cleared up simultaneously, so iterative cycles rinses, extracts, until dewatering well is dredged.
The beneficial effects of the utility model are: simple in structure, cost is lower, can quickness and high efficiency ground to because the dewatering well of silt blocking is dredged cleaning.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Detailed description of the invention
Embodiment
The structure of the present embodiment as shown in Figure 1, a kind of dewatering well dredger, comprise deep well submerged pump 7, the bottom of deep well submerged pump 7 connects sandstone filter 4 through fixture 6, the bottom of sandstone filter 4 connects chimney filter 1 by water under high pressure conversion head 2, the side of water under high pressure conversion head 2 is communicated with high-pressure water pipe 3, and the entrance of high-pressure water pipe 3 is provided with booster pump 13.Fixture 6 is fixed on the bottom of deep well submerged pump 7 by iron wire, make fixation.Sandstone filter 4 is cylindric, stainless steel, and the diameter of sandstone filter 4 is identical with deep well submerged pump 7 diameters, in the uniform filter bores of periphery, to filter slime water.The height of high-pressure water pipe 3 exceeds the upper end of deep well submerged pump 7, and deep well submerged pump 7 is fixed high-pressure water pipe 3 by iron wire.
The upper end stationary rope 16 of deep well submerged pump 7, to put into whole device the dewatering well of obstruction.Wherein, after rinsing, mud imports and exports 5, can be so that mud enter, and the top of downcast well pipe 8 is well side backfill clay material 9, and bottom is well side Cast-in-situ Piles in Sand-filling building stones 10, and deep well submerged pump 7 is electrically connected with three grades of switchboxs 12 by water pump cable 11.The delivery end of the water pump water-supply-pipe 15 of deep well submerged pump is provided with gate valve 14.
When work, sandstone filter is fixed on to deep well submerged pump end with iron wire, after high-pressure water pipe and deep well submerged pump adopt iron wire to fix reliably, the dewatering well of obstruction put into this dredger by the rope that use is fixed on deep well submerged pump, and chimney filter stretches into the mud layer of dewatering well bottom precipitation.When dredging, first the backwash booster pump of high-pressure water pipe entrance is opened, utilize the impact force of hydraulic giant to rush falling into the earth, the sandstone etc. that cause well to stop up in dewatering well, the impact type backwash chimney filter that simultaneously utilizes high-pressure water pipe, impacts, rinses what plug silt, further makes silt rush.What plug silt is after impacting, rinsing, become slime water, slime water passes through sandrock filter, sandstone is filtered in sandrock filter, high-pressure water pipe is opened and is rinsed after approximately 3 minutes, opens deep well submerged pump and carries out extracting of slime water, every about 15 minutes, this device is taken out sandstone filter is cleared up simultaneously, so iterative cycles rinses, extracts, until dewatering well is dredged.
Facts have proved, this device has the following advantages the dewatering well due to silt blocking in dredging:
1, the dewatering well of dredge blockage, only needs to adopt submersible pump and giant, just can dredge effectively and quickly dewatering well, reduces construction cost and construction speed, opens without the brill that re-starts dewatering well.
2, adopt sandstone filter, the sandstone being blocked in dewatering well effectively can be cleared up, dredging, cleaning are thoroughly.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
