Description

A precast pile implantation device for stake board road bed

Technical Field

The utility model relates to a pile foundation construction technical field, especially a device is implanted to precast pile for stake slab road bed.

Background

The pipe following while drilling method is a middle digging pile sinking method. During construction, the long spiral drill rod connected with the drill bit with the hole expanding function penetrates through the precast tubular pile, and the bottom end of the precast tubular pile is excavated to form a hole. When drilling is needed, the power head rotates forwards, a hole expanding wing plate of the hole expanding drill bit is opened, the drill bit rotates to excavate soil at a distance below the bottom end of the precast tubular pile, drilling residues are conveyed by the blade of the screw drilling rod to be discharged through the tubular pile hole, and the precast tubular pile sinks along with the drill bit by means of self weight during drilling. If the precast tubular pile is not smooth when being blocked in the pile sinking process, a vibration exciter can be started to vibrate and press the precast tubular pile to break through (the vibration exciter is arranged at the upper end of the power head by the conventional clamping vibration power head, so that the stroke of the vibration exciter on a guide rail is limited). After the pile is connected by the drill and the pile is connected to the calibrated depth, the power head reversely rotates to withdraw the reaming wing plate for removing the slag, concrete is poured at the pile bottom, the vibration exciter is started to press the prefabricated pipe pile to be seated in the hole bottom, the drill rod is drawn out, and the drilling machine moves. And then, performing high-pressure grouting treatment on the outer side of the precast tubular pile by grouting equipment to form a pile.

In the existing precast pile planting technology, a crawler crane is mainly adopted to lift a pile and then sink the pile by means of the self weight of a pile body or to plant the pile by means of external force applied by a static pressure machine or hammering and the like in the pile planting process, for example, a static drilling root-planting pile construction method (CN 105649073A) and a non-prestressed centrifugal high-strength concrete pile planting pile construction method (CN 105421445A) are pile sinking by means of the self weight of the pile body; a construction device and a construction method (CN 104947652B) of a stiff composite pile (CN 202298602U) and a long spiral drilling cement mortar wall protection type implanted pipe pile depend on a static pressure machine or a hammering pile to apply external force to sink the pile.

No matter in the concrete precast pile construction, a certain soil squeezing effect exists no matter hammering and static pressure are adopted, a pile body is damaged to a certain extent, in recent years, some construction methods that non-soil squeezing (half soil squeezing) is firstly drilled (pre-stirred) and then the precast pile is implanted exist, and when the pile is sunk depending on the dead weight of the pile body, the situation that the pile is not sunk in place can occur under the condition that the geological conditions and the construction conditions are complex.

When the traditional static pressure machine is used for pile planting, the following problems exist:

when the tonnage of the static pressure machine is too large, the volume of the static pressure machine body is too large, the occupied area is large, the static pressure machine body is difficult to construct in a flow mode with equipment for drilling construction, a large distance needs to be kept between the static pressure machine body and a drilling machine, and the construction efficiency is low; when the tonnage of the static pressure machine is too small, the pile pressing force is too small, and the expected effect cannot be achieved. In addition, the diameter of the drilled hole is larger than the diameter of the pile body, so that the verticality control difficulty of the pile in the pile planting process is high.
