Abstract:
A side wall fixing apparatus applied in a drilling system, comprising a reinforcing barrel (3), side wall fixing nails (1), and a padlock (2) linked within the reinforcing barrel (3). The reinforcing barrel (3) is a 3-piece circular arc structure. The 3 pieces, when combined, form a circle-shaped barrel structure. Each piece of the reinforcing barrel (3) is provided with a plurality of fixing holes. The side wall fixing nails are inserted into the fixing holes to fix the reinforcing barrel (3) on a side wall for transverse fixation. The padlock (2) linked within the reinforcing barrel (3) longitudinally links the circle-shaped fixing barrel (3) which is formed by upper and lower groups. The beneficial effects of the described side-wall fixing apparatus are: facilitating an increase in transverse supporting strength of the circular structure; the 3-piece structure being easy for assembly and dismantling and being able to be repeatedly used; and being able to facilitate a plurality of series combinations in the longitudinal direction to achieve application at different depths.
