In figure, 1: deep-well; 2: silt particle; 3: well-flushing pipe; 4: high-pressure air hose; 5: air compressor machine; 6: sand removing hole; 7: wedge shape inhales husky mouth.
Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
In describing the invention, it should be noted that, term " on ", D score, " interior ", " outward " " top ", the orientation of the instruction such as " end " or position relationship be based on orientation shown in the drawings or position relationship, it is only simplified characterization of the present invention for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as and limit the present invention.
In describing the invention, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " being connected ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also indirectly can be connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, concrete condition above-mentioned term concrete meaning in the present invention can be understood.
As shown in Figure 1, ground precipitation deep-well well washing apparatus of the present invention comprises well-flushing pipe 3, high-pressure air hose 4 and blowing element; The bottom of well-flushing pipe 3 is provided with wedge shape and inhales husky mouth 7, and well-flushing pipe 3 is arranged in deep-well 1, and its bottom is arranged in the silt bottom deep-well 1, and deep-well 1 mouthful is stretched out on top, and the top of well-flushing pipe 3 arranges sediment ejection opening; High-pressure air hose 4 is arranged in well-flushing pipe 3, and well-flushing pipe 3 is stretched out on top, and is connected with blowing element.
