Pouring type pile driver and pile driving method therefor

Abstract

The invention relates to a pouring type pile driver and a pile driving method therefor. A traditional pile driving mode is changed, a pile body does not be reserved underground, pile driving and pouring are simultaneously finished, and secondary pouring is not needed, and thereby a firm pile driving operation of a pile body formed by cement filling materials can be realized; the pile driving method is efficiently and inseparably combined with equipment disclosed by the invention; and the pile driver is used and is matched with the pile driving method disclosed by the invention, so that efficient combination of the pile driver and the pile driving method is realized, cement materials are enabled to be poured while the pile is pulled after the pile driving operation is finished, no time slot is reserved, and the cement materials quickly fill a space from which the pile body is pulled; and in addition, after the cement materials are poured and solidified, the contact area between the bottom of the solidified cement pile body and the bottom surface is greater, and the top of the solidified cement pile body is tightly contacted with the space from which the pile body is pulled to form column table-shaped structures with different sizes, so that the stability of the pile body is enhanced.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a pile driving device, in particular to a pouring type pile driver and a pile driving method thereof. 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...

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
