Embodiment 1

[0038] Embodiment 1: Horizontal arrangement of I-shaped towers

[0039] When the I-shaped tower of a double-row multi-axis pile machine of the present invention is arranged horizontally, the pile types can be processed such as Figure 5 Shown, including: "before three and then three", "before three and then two", "before two and then three", "before two and then two", "before one and then two", "before two and then one" or "before one The beneficial effect of the double-row pile type with any combination of the latter "and other types is that it can adapt to the actual pile spacing array size requirements to the greatest possible extent when increasing the pile forming operation.

[0040] See attached Figure 2~4 , a double-row multi-axis pile driver, including: sprocket 1, I-shaped tower 2, two sets of lifting chains 3, six rotating heads 4, rotating head frame one 5 and rotating head frame two, six hollow drill rods 6. Six sets of lower-mounted square turntables, the lower...

Embodiment 2

[0054] Embodiment 2: Longitudinal arrangement of I-shaped towers

[0055] See attached Figure 6-8 , when the I-shaped tower 2 is vertically arranged, the pile types that can be processed include: "two in front and two in back", "two in front and two in front", "two in front and one in back" or "one in front and one in back" and other arbitrary combinations Double row pile type.

[0056] Layout of upper chassis 8, lower chassis 9, ram 10, longitudinal movement cylinder 20, transverse movement cylinder 21, four support legs 19, a set of hydraulic and electric operation table 16, hydraulic oil tank 17 and electric control cabinet 18 Same as Embodiment 1.

[0057] Setting: The horizontal direction of the double-row multi-axis pile machine is the Y-axis direction, the vertical direction is the X-axis direction, and the height is the Z-axis direction; Figure 8 In the I-shaped tower 2 shown, the neutral plane is parallel to the X axis.

[0058] See attached Figure 6-8 , when ...

Abstract

The invention discloses a double-row multi-shaft pile machine which is an important improvement on the basis of the disclosed patent multifunctional ultra-large-diameter stirring pile machine provided with torsion compensation device (ZL201520547506.4). The double-row multi-shaft pile machine can punch six pile holes in two rows at most each time, and the machined pile holes can be distributed transversely or longitudinally. A tower of the pile machine is I-shaped and erected on an upper underframe platform transversely or longitudinally, a row of underneath type square rotary tables are arranged at the lower part of each of two sides of the tower, the number of the square rotary tables in each row is 1-3, one power system drives one or two square rotary tables, the square rotary tables are used for driving hollow drill pipes to rotate forwards or reversely, and every three or two hollow drill pipes share one pressurization system. The pressurization systems are used for driving drill bits to perform pressurization downwards when the hollow drill pipes rotate clockwise to drill downwards or perform pressurization upwards when the hollow drill pipes rotate anticlockwise and the drill bits are lifted. The pile machine is good in stability, high in adaptability, high in operation efficiency, capable of meeting requirements of different pile models and high in cost performance, and the quality of formed piles is high.

Description

technical field [0001] The invention relates to a double-row multi-shaft pile driver, in particular to a double-row multi-shaft pile driver capable of simultaneously driving double-row multi-shaft piles. It belongs to the technical field of pile machinery equipment in the construction machinery industry. Background technique [0002] Among the foundation treatment methods commonly used in existing buildings, the pile engineering treatment methods for load-bearing piles include: cement-soil mixing piles and hole-forming cast-in-place piles, wherein the cement-soil mixing piles use cement as a curing agent, and are placed deep in the foundation by a deep mixer. The soft soil and the curing agent (slurry or powder) are forced to mix, and a series of physical and chemical reactions occur between the curing agent and the soft soil, so that the solidification becomes a cement reinforcement with integrity, good water stability and high strength. , form a composite foundation with ...
