Detailed Description
The present invention will be further explained with reference to the accompanying drawings. As shown in fig. 1 and 2, the present invention mainly comprises a grouting pipe main structure and an upper electric driving rotation structure diagram. The middle electric drive rotating structure comprises a rotating handheld rod 1; 2-top fixed end; 3-power driver external structure; 4-internal fixation means; 5-connecting the electric wire; 6-a generator. Slip casting pipe major structure includes: 7-grouting pipe top structure; 8-grouting pipe body; 9-connecting ports on two sides; 10-outside thread; 11-a collar; 12-a plug upper device; 13-a tapered plug; 14-external drill threads; 15-screws; 16-screw thread; 17-screw fixation means. Rotatory handheld pole 1 is fixed at upper portion electric drive revolution mechanic top through top stiff end 2, and electric drive ware outer structure 3 comprises stainless steel construction, plays the effect of protection inner structure, prevents simultaneously that the corruption from rustting, links to each other with generator 6 through connecting wire 5. Under the drive of electric power, upper portion electric drive revolution mechanic links to each other with slip casting pipe major structure slip casting pipe top end structure 7 through inside fixing device 4, and the 7 outsides of slip casting pipe top end structure are the hexagon structure, and the inboard is circular, and the outside is convenient for be fixed by inside fixing device 4, and the rotary drilling is under electric power. Two side connectors 9 are arranged on two sides of the lower portion of the grouting pipe body 8, a plug upper device 12 is arranged on the upper portion of a conical plug 13 at the bottom, and a lantern ring 11 is fixed to the plug upper device 12 in a welding mode.
