Abstract
The utility model relates to a construction machinery specifically is a well -flushing machines. The problem of after being buried, the precipitation well can't draw water is solved, including getting the feed cylinder, be equipped with the sawtooth getting feed cylinder downside edge, the bobbin base of getting the feed cylinder for sealing the form, get the feed cylinder top and be connected with drilling rod, drilling rod end -to -end connection rig through connecting reinforcement. Through using well -flushing machines to the precipitation well of burying clearance back, make the effect reach anticipated effect, saved because of the sole oozes the cost -push that causes, make the precipitation well play real effect, reached anticipated effect.
Description
Technical field
The utility model relates to a kind of construction machinery, is specially a kind of well-flushing facility.
Background technology
Dewatering well is the well of beating for lowering of watertable, puts into water pump groundwater abstraction after having beaten, and reduces the water level of underground water. It is one of measure ensureing foundation ditch smooth construction. The pipe well structure pipe well buried depth 27.0m of dewatering well, well diameter 600mm, without sand cement pipe diameter 400mm, hole between well casing and wellhole is filled the top 2.0m clay filled 2.0m that obturages by following requirement and is adopted below 2-4mm granule filling 10.0m to adopt 6-8mm granule filling down to shaft bottom, for chimney filter outside galvanized wire be wound around and with nylon cloth or 80 order silk screens parcel firmly.
But reality is at the construction field (site) when earth excavation, indivedual dewatering wells are because of working measure and protect improperly, cause dewatering well buried, cannot draw water, and make dewatering well lose precipitation effect, do not reach expection object.
Summary of the invention
The problem that the utility model cannot draw water after buried in order to solve dewatering well, provides a kind of well-flushing facility.
The technical solution of the utility model is that a kind of well-flushing facility, comprise feeding cylinder, are provided with sawtooth in feeding cylinder lower edge, are closed at the cylinder end of feeding cylinder, above feeding cylinder, are connected with drilling rod by connecting reinforcement, drilling rod end connection rig.
Clean the process of earth in dewatering well: first with giant, earth in well is rinsed, use sewage pump draining, flushing limit, limit reduces water pump. Until earth is all rinsed away in well, only, after the large particulate matter such as remaining stone, feeding cylinder is put into shaft bottom, open rig, drilling rod drives the rotation of feeding cylinder, and in rotary course, sawtooth stirs stone or filtrate, just in time falls in feeding cylinder. Then promote feeding cylinder, until shaft bottom stone filtrate is cleared out until reach the requirement degree of depth.
After using well-flushing facility described in the utility model to the dewatering well cleaning of burying, effect is produced a desired effect, save because sole oozes out the cost causing and increased, make dewatering well play real effect, produce a desired effect.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-rig, 2-feeding cylinder, 3-drilling rod, 4-sawtooth, 5-dewatering well.
Detailed description of the invention
As schematically shown in Figure 1, a kind of well-flushing facility, comprise feeding cylinder 2, are provided with sawtooth 4 in feeding cylinder 2 lower edge, and the cylinder end of feeding cylinder 2 is closed, and feeding cylinder 2 tops are connected with drilling rod 3 by connecting reinforcement, and drilling rod 3 ends connect rig 1.
Described drilling rod 3 is more piece drilling rod, and connects section by section by screw thread, can lengthen according to the degree of depth of dewatering well like this.
