Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With reference to fig. 1 and 3, the utility model discloses an assembled fore shaft circle for digging a hole manually, which comprises a fore shaft circle body 1, a fixing member 2 and a hook 3. The fore shaft body 1 comprises a first fore shaft part 11 and a second fore shaft part 12 which are semi-annular, and the first fore shaft part 11 and the second fore shaft part 12 are prefabricated in a factory in a mode of formwork pouring. The upper surface of the splicing end of the first locking piece 11 and the second locking piece 12 is provided with a vertical first through hole 13, and the middle section of each of the first locking piece 11 and the second locking piece 12 is provided with a second through hole 14. During construction, the first locking piece 11 and the second locking piece 12 are spliced relatively along the position of the exploratory hole, and two parallel rods at two ends of the door-shaped fixing piece 2 are respectively inserted into the first through holes 13 of the first locking piece 11 and the second locking piece 12, so that the two semicircular locking pieces are fastened together to form the complete circular locking ring body 1. Constructors need to put down rope ladders or guide various lines into the detection holes in the process of descending the well, and hooks 3 are fixed on the periphery of the locking collar body 1.
