Description
Technical field
The present invention relates to a kind of hole-forming devices, for the pore-forming in building field work progress.
Background technique
Traditional pore-forming is all to inject place to be punctured using water, needs retaining wall, then carries out brill digging, this mode,
Because being water and mud mixing, it is easy to appear collapse hole, first needs to solve the problems, such as transport, the slurry dug out will transport away,
During transportation, it is also easy to exist and trickle down, it is ineffective to environmental protection；It second is during boring digging, the equipment needed is more,
Therefore, more manpower and material resources are just generated in the construction process, to cause the increase of the production cost of enterprise.
Summary of the invention
To overcome the shortcomings of existing technologies, the present invention provides a kind of hole-forming device, the technical scheme is that
A kind of hole-forming device, including casing are equipped with hydraulic cylinder leg in the upper port of the casing, in the hydraulic cylinder leg
On hydraulic cylinder is installed, the piston rod of the hydraulic cylinder is directed toward the lower port of casing, is equipped with axis in the end of the piston rod
It holds, an at least hinged swing rod, the other end of the swing rod are hinged on the side of guide pad on the outer ring of the bearing, and described leads
Compression bar is installed to the bottom of block, which is arranged along the vertical direction, is equipped with firming plate in the bottom end of the compression bar, the firming
Plate is vertically arranged with compression bar, and the inner wall of the casing is provided with guide groove, guide groove setting wave-shaped, guides guide pad
It is slided in the inner wall of casing, so that circumferencial direction of the firming plate in casing along casing be driven to move, realizes firming pore-forming.
The swing rod be it is several, the circumferencial direction along bearing is evenly arranged.
The lower end surface of the firming plate is inclined-plane, presents a liter shape from the center of casing to outer wall.
The invention has the advantages that pressing hole using dry method, during pressing hole, the not generation of mud, also there is no transports
The problem of, and required equipment is less, reduces entreprise cost.
Detailed description of the invention
Fig. 1 is agent structure schematic diagram of the invention.
Specific embodiment
The invention will now be further described with reference to specific embodiments, the advantages and features of the present invention will be with description and
It is apparent.But examples are merely exemplary for these, and it is not intended to limit the scope of the present invention in any way.Those skilled in the art
Member it should be understood that without departing from the spirit and scope of the invention can details to technical solution of the present invention and form into
Row modifications or substitutions, but these modifications and replacement are fallen within the protection scope of the present invention.
Referring to Fig. 1, the present invention relates to a kind of hole-forming devices, including casing 1, are equipped in the upper port of the casing 1 hydraulic
Jar support 2 is equipped with hydraulic cylinder 3 on the hydraulic cylinder leg 2, and the piston rod 4 of the hydraulic cylinder 3 is directed toward the lower port of casing 1,
The end of the piston rod 4 is equipped with bearing 5, an at least hinged swing rod 6 on the outer ring of the bearing 5, the swing rod 6
The other end is hinged on the side of guide pad 7, and the bottom of the guide pad 7 is equipped with compression bar 8, which sets along the vertical direction
It sets, firming plate 9 is installed in the bottom end of the compression bar 8, which is vertically arranged with compression bar 8, in the inner wall of the casing 1
It is provided with guide groove, guide groove setting wave-shaped, guidance guide pad is slided in the inner wall of casing 1, thus with dynamic pressure
Circumferencial direction of the native plate 9 in casing along casing moves, and realizes firming pore-forming.
In order to improve compacting efficiency, it can set several for swing rod, the circumferencial direction along bearing is evenly arranged.
The lower end surface of the firming plate 9 is inclined-plane, presents a liter shape from the center of casing 1 to outer wall.
Working principle of the present invention is as follows: after starting hydraulic cylinder, the piston rod driving swing rod and compression bar of hydraulic cylinder are moved down,
The external pressure for realizing the soil in region corresponding to firming plate keeps soil mobile from the interior of casing；When compacting finishes firming plate
Behind region corresponding to area, the piston rod of hydraulic cylinder is moved up, and is moved at this time due to guide pad along guide groove, be moved to it is upper
The adjacent region in one region continues to suppress, and is sequentially completed external pressure native in casing, after the soil pressure in casing is empty, so that shield
Cylinder moves down respective distance, continues the compacting of next depth.
