A kind of double-deck piling equipment

Abstract

The invention relates to double-layer pile sinking equipment. A pile body inner pipe is installed inside a pile body outer pipe in a sleeved mode. A pile head is connected to the lower portion of the pile body outer pipe. An inner pipe connector connected with the pile body inner pipe is arranged on the upper portion of the pile head. The pile head is hollow. The inner pipe connector is communicated with the pile head. A plug is movably connected with the lower portion of the pile head through an iron chain. The pile body outer pipe and the pile body inner pipe are connected with each other through bolts. The pile body outer pipe and the pile body inner pipe operate downwards at the same time. After pile sinking operation is completed, cement pouring materials are fed into the inner pipe through external pouring equipment when the pile body inner pipe is lifted upwards, a cavity generated by the pile body outer pipe is filled, pouring operation of a cement pile body is achieved, the pile body is no longer reserved underground, piling and pouring are completed at the same time, the natural pile body is formed after solidification, pouring does not need to be conducted again , and therefore firm pile sinking operation of the pile body by means of the cement filling materials can be achieved.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a piling device, in particular to a double-layer piling device. Background technique [0002] The pile driver is composed of pile hammer, pile frame and auxiliary equipment. The pile hammer is attached to two parallel vertical guide rods at the front of the pile frame, commonly known as the gantry, and is hoisted with a lifting hook. The pile frame is a steel structure tower frame, and a hoist is provided at the rear of it for lifting piles and pile hammers. There is a guide frame composed of two guide rods in front of the pile frame, which is used to control the direction of pile driving, so that the pile can accurately penetrate into the ground according to the designed orientation. Pile hammers can be divided into drop hammers, steam hammers, diesel hammers, hydraulic hammers, etc. according to the power source of the movement. A pile driver is a pile machine that uses impact force...

AI Technical Summary

Problems solved by technology

This piling method needs to waste more resources and equipment

During the piling operation, due to the limitation of the diameter of the pile body, after the pile operation is completed, the pile body remains in the ground, the diameter of the pile body remains unchanged, and the force points are all made of the pile body, and the pile body is unevenly received from top to bottom, affecting construction of superstructure

The piles are left in the ground as necessary reserved parts, which cannot be reused repeatedly, wasting resources

In addition, the traditional pile driver is prone to defective piles during use. The traditional treatment methods include expanding the cap, re-pile in situ, connecting piles, sinking the pile core, filling piles, drilling reinforcement, changing the construction method or modifying the design plan.

Some major pile foundation accidents are difficult to deal with and cost a lot of money

Once defective piles appear, adopting one of the above audit methods will result in increased cost and expenditure, and may cause defects after the overall design is changed.

Therefore, it is easy to cause inconvenient construction by using traditional pile drivers to reserve piles underground. Once defective piles appear, it will cause lags in production and construction period, and bring huge economic losses to the construction party. bring security risks
