By adopting the structure, the limiting rod is inserted on the limiting column, so that the sleeve barrel can be prevented from doing circumferential motion in the cavity, the situation that the extruded soil cannot smoothly enter the sleeve barrel along the guide groove is avoided due to the fact that the grooving at the bottom of the sleeve barrel and the groove-penetrating dislocation on the side wall of the sleeve barrel are avoided when the sleeve barrel moves downwards.

More preferably: the outer wall of the limiting column is provided with threads and is provided with a nut matched with the threads.

Adopt above-mentioned structure, fix the gag lever post on spacing post through the cooperation of nut and screw thread to make the position of cover bucket and body fixed, prevent the in-process of body downstream because soil upward movement gets into the gap of cover bucket and cavity bottom gradually, thereby make the cover bucket shift up, lead to wearing the circumstances that groove and fluting dislocation made soil can't get into smoothly to take place.

More preferably: the top outer wall cover of body is equipped with the horizontally base, it has a plurality of screw holes to open vertically in the base, and screw hole internal thread fit has from up the fixing bolt who spirals down.

Adopt above-mentioned structure to the base is as the installation stake, and fixing bolt up spins to the highest point, and after the pile is accomplished, is connected with ground facility through fixing bolt, makes ground facility and the fixed of stake more convenient.

More preferably: a groove is formed in the top wall of the base and coaxial with the threaded hole, and a nut in threaded fit with the fixing bolt is arranged in the groove.

Adopt above-mentioned structure, cause the direction of force to be crooked easily during the plane application of force to the unevenness, screw down fixing bolt and make fixing bolt's top flush with the base top, even surface is convenient for even application of force, it squeezes into the underground perpendicularly to change in, the back is accomplished in the pile, take off the nut through screwing the nut, and rotate fixing bolt's screw thread post through instruments such as vice, thereby make fixing bolt along with the rotation in the screw hole stretches out the base top gradually, thereby realize being connected of screw thread post and ground facility.

More preferably: and a plurality of drainage holes are formed in the side wall of the body.

Adopt above-mentioned structure, the setting of discharge orifice, when carrying out concrete placement, the concrete receives the extrusion to flow out from the discharge orifice because self receives the reason of gravity, and after the concrete solidifies, form a plurality of concrete columns of pegging graft in the soil horizon to increase the steadiness of stake.

More preferably: and a hanging ring is arranged at the top of the limiting rod.

By adopting the structure, the arrangement of the lifting ring enables the sleeve barrel to be more conveniently pulled out from the cavity of the body, the nut is screwed out from the limiting column through a crane or other hoisting modes, and the lifting ring is hooked to pull out the sleeve barrel.

To sum up, the utility model discloses following beneficial effect has:

1. the solid arrangement of the bottom of the body enables the gravity center of the body to move downwards, the piling process can be more stable, and due to the existence of the guide groove, after the soil is extruded, along with the continuous downward movement of the pile, the soil can enter the sleeve barrel through the through groove and the open groove along the guide groove, so that the downward movement of the pile is smoother, after the pile is completely driven into the soil, the sleeve barrel is pulled out of the body, the soil in the sleeve barrel is poured out, concrete is poured into the cavity of the body, due to the action of gravity, the concrete can flow downwards along the cavity and flow outwards from the through groove, and after the concrete is condensed, an irregular pile body is formed and inserted into a soil layer, so that the pile can be more stable;

2. the setting of discharge orifice, when carrying out concrete placement, the concrete receives the extrusion to flow out from the discharge orifice because self receives the reason of gravity, and after the concrete solidifies, form a plurality of concrete columns of pegging graft in the soil horizon to increase the steadiness of stake.
