With the continuous development of China's underground continuous wall construction technique, Major diameter downhole hammer is in the fortune of ground-connecting-wall construction field
With more and more extensive, using down-hole hammer, firm ground carried out after multiple spot crushes, then grooving is carried out using equipment such as hydraulic pressure millings, apply
Work efficiency rate is remarkably improved.But time and effort consuming when current Major diameter downhole hammer positions in aperture, precision is low, hole position mark is easily moved
The factor such as in dynamic, work progress in the hole drill pipe wobbling amplitude is excessive, also badly influences the construction quality of ground-connecting-wall.
Content of the invention
Technical problem to be solved in the utility model is to provide a kind of Major diameter downhole hammer construction aperture positioner, can
To solve the problems, such as that aperture positioning takes time and effort, precision is low, construction when drill pipe wobbling big, positioning is rapid, accurately, efficiently, to brill
The guiding of bar and effect of contraction substantially, are remarkably improved the construction quality of ground-connecting-wall.
For solving above-mentioned technical problem, the utility model be employed technical scheme comprise that：A kind of Major diameter downhole hammer construction
Aperture positioner, including top panel and lower panel, top panel uniformly offers multiple pore sizes with down-hole hammer, position
The upper circular opening matching, lower panel uniformly offers the lower circular opening that multiple and upper circular opening matches, above
Pass through many guide protective tubes between plate and lower panel to connect, each guide protective tube is respectively perpendicular that to be welded on top panel relative with lower panel
On the upper circular opening and lower circular opening answered, top panel is provided with stiffening frame, two sides of stiffening frame are respectively installed
There are hydraulic top movable supporting legs and counter-force supporting leg.
It is respectively arranged with linkage levelling screw and hanger on four angles of stiffening frame.
The axis of guide protective tube is respectively perpendicular to top panel and lower panel.
The Major diameter downhole hammer construction aperture positioner that the utility model provides, by top panel and lower panel, can one
Secondary property completes the positioning work of multiple hole positions；By stiffening frame, top panel is reinforced, stiffening frame is provided with leveling spiral shell
Bar, adjustable apparatus horizontal level；Stiffening frame is provided with hydraulic top movable supporting legs and counter-force supporting leg, the axis of adjustable apparatus
Device is simultaneously securely fastened to ground-connecting-wall and leads on wall by position；Guide protective tube is vertically welded in upper and lower panel corresponding hole site, latent
Drift drilling when, drilling rod is played guiding and effect of contraction, can solve aperture positioning take time and effort, precision is low, construction when bore
Bar swings big problem, and positioning is rapid, accurate, efficient, and the guiding to drilling rod and effect of contraction substantially, are remarkably improved ground-connecting-wall

Casing.
The course of work of the present utility model is as follows：
By top panel 3 and lower panel 8, can disposably complete the positioning work of multiple hole positions；Will be upper by stiffening frame 1
Panel is reinforced, and stiffening frame 1 is provided with linkage levelling screw 5, adjustable apparatus horizontal level；Stiffening frame 1 is provided with hydraulic pressure
Top movable supporting legs 2 and counter-force supporting leg 4, device is simultaneously securely fastened to ground-connecting-wall and leads on wall 11 by the axial location of adjustable apparatus；
Guide protective tube is vertically welded in upper and lower panel corresponding hole site, in DTH drilling, drilling rod is played with guiding and constraint is made
With, can solve the problems, such as that aperture positioning takes time and effort, precision is low, construction when drill pipe wobbling big, positioning is rapid, accurately, efficiently,
Guiding to drilling rod and effect of contraction substantially, are remarkably improved the construction quality of ground-connecting-wall；The design of hanger 6 facilitate mobile and
Lifting.
