Alignment.
Referring to figs. 2 and 3, in use, boring a hole on dirt floor, nut 41 is removed, towards the side for moving up ground pile 4
Do not interfere to ground pile two levers to turn to using pin as axis to rotation ground pile 4 to be close together substantially and extending direction prolongs with ground pile
Stretch the almost the same position in direction, two levers 2 are that axis is turned to and is close together substantially and the same ground pile of extending direction with pin 21
Extending direction is almost the same, and (can not fully come together between two levers does not have gap, and otherwise ground pile can not be inserted into two
Between lever), it is aligned lever seat 1 with hole, makes lever 2 and lever seat 1 insert in the hole and arrive needs by pushing away ground pile 4
Depth, rotation ground pile 4 draw close ground pile towards lever 2, and ground pile 4 is inserted between two levers and drives two levers with pin simultaneously
21 is axis rotates and separates, and separated result is that lever increases with the result of bolt so that lever is stuck in hole, then by pedestal
71(is referring to Fig. 1) on the ground shelved and 711 sets of the connecting hole upper ends in ground pile, then screw on nut 41 and locking nut to
Pedestal is fixed on dirt floor wall by realization.It is to be stuck on clamping joint 42 to be rotated by spanner when rotating ground pile 4.When
Ground pile 4 drive the first lever 2-1 and the second lever 2-2 rotation and separate during, jacking block 2-21 is inserted into through-hole 2-111
Depth gradually deepen, jacking block far from the end face 2-214 of pin abut to slide bar 2-121 to through end 2-12 from interlude 2-11
Interior ejection (namely making the first lever 2-1 elongated), to play the role of improving snap effect.
Embodiment three, with the difference of embodiment two are as follows:
Referring to fig. 4, ground pile 4 is rotatably connected to the snap ring 43 along ground pile circumferentially extending.Snap ring 43 passes through two stainless steel steel
Silk 44 correspondingly links together two levers 2.The program can be by deviating from 4 post-tensioning stainless steel steel wire 44 of ground pile
The rotation of two levers 2 is driven to be closed up and horizontal, to take out from hole.
