Abstract
The invention relates to the field of construction devices for pile foundation holes, in particular to a suction type device for cleaning muck at the bottom of a pile foundation hole. The suction type device for cleaning the muck at the bottom of the pile foundation hole comprises a drill rod and an oil cylinder arranged inside the drill rod. The suction type device for cleaning the muck at the bottom of the pile foundation hole is characterized by further comprising a cylinder body, wherein the cylinder body is arranged at one end of the drill rod and used for sucking and storing the muck; a piston is arranged in the cylinder body, a sealing device is arranged on the side wall of the piston to enable the side wall of the piston to contact the inner wall of the cylinder body closely, and the piston is connected with a piston rod of the oil cylinder in the drill rod; the end, connected with the drill rod, of the cylinder body is sealed, the other end of the cylinder body is provided with an opening, and a rotary type door shield is arranged outside the opening; and through holes are formed in the side wall of the cylinder body. Due to the design, the suction type device for cleaning the muck at the bottom of the pile foundation hole has the advantages that suction force can be generated through motion of the piston in the cylinder body, the thin muck at the bottom of the pile foundation hole can be sucked into the cylinder body and transported to the ground, and therefore the bottom of the pile foundation hole can be effectively cleaned, and forceful quality assurance is provided for a pile grouting process in the following step.
Description
Technical field
The present invention relates to pile foundation hole construction equipment field, be specially slag cleaning device at the bottom of a kind of drawing-in type pile foundation hole.
Background technology
When carrying out filling pile construction, need first pile foundation hole to be made complete, penetration concrete in the pile foundation hole again, both can become pile body after it is solid afterwards.Final step when making pile foundation hole is the mud mixture at the bottom of the cleaning pile foundation hole, and described mud mixture in the pasty state or the sposh shape; The method of existing cleaning pile foundation hole bed mud aqueous mixtures mostly is to adopt to dig sweeps the formula cleaning; So, due to the seal of cleaning plant own and sposh shape or pasty state mud mixture mobility large, be difficult to that thoroughly cleaning is clean with the dregs at the bottom of pile foundation hole; Yet due to the existence of dregs, the quality after concrete casting is shaped will be affected, and is also that the quality of pile body can be affected, and has hidden danger of quality.
Summary of the invention
The object of the invention is to overcome the defective of dregs cleaning at the bottom of existing pile foundation hole, dregs cleaning plant at the bottom of a kind of drawing-in type pile foundation hole that moves to receive dregs at the bottom of pile foundation hole with drawing-in type is provided.
In order to achieve the above object, the present invention is achieved in that
Slag cleaning device at the bottom of a kind of drawing-in type pile foundation hole, it comprises drilling rod and is located at the interior oil cylinder of drilling rod, also comprises the cylindrical shell for the dregs of attracting deposit that is arranged at drilling rod one end; Be provided with piston in described cylindrical shell, piston side wall is provided with sealing device and makes close contact between itself and cylinder inboard wall, and the piston rod of the oil cylinder in piston and drilling rod is connected; The end sealing that cylindrical shell is connected with drilling rod, the other end of cylindrical shell is provided with opening, and open outer side is provided with the swinging door shield; Have through hole on the sidewall of cylindrical shell.
Slag cleaning device at the bottom of described drawing-in type pile foundation hole is provided with pre-tightening apparatus between cylindrical shell and swinging door shield; Described pre-tightening apparatus is preloading spring.
Slag cleaning device at the bottom of described drawing-in type pile foundation hole, cylinder body outer wall is provided with drainage hood.
Slag cleaning device at the bottom of described drawing-in type pile foundation hole, the through hole on the described sidewall that is opened in cylindrical shell, it is positioned at cylindrical shell and cylinder piston rod link one side.
Slag cleaning device at the bottom of described drawing-in type pile foundation hole, swinging door shield lateral surface is provided with tooth.
The present invention adopts above-mentioned design, and its advantage is to produce suction by the motion of cylindrical shell inner carrier, the shoddye soil at the bottom of pile foundation hole can be pumped in cylindrical shell and with it and be transported to ground.At the bottom of can effectively clearing up pile foundation hole, fill with the stake operation for next one strong quality assurance is provided.
