Description

[Detailed Description of the Invention] (Purpose of the Invention) This invention is a method of suspending and inserting piles into pile holes drilled in the ground during pile embedding work carried out as one of the ground reinforcement works. The purpose of this invention is to provide a pile hanging device having a novel structure with excellent pile hanging operability.

(Prior Art) Nowadays, civil engineering facilities and buildings have become larger and must be built in various soil environments, so ground reinforcement measures are an extremely important work item. Among these soil reinforcement measures, the method of embedding piles in the ground is widely adopted as a simple and effective method.

Working machines for forming pile holes include, for example, a hammer grab such as a Benoit machine, a rotating packet such as a Kalweld machine, and a rotating bit such as a reverse circulation machine. Several, and increasingly improved, systems have been provided, such as those by , and efforts are being made to improve work efficiency, reduce noise, and improve safety.

On the other hand, equipment that moves piles, such as moving piles loaded onto a truck to a predetermined location, or moving them from a predetermined location to a pile hole and inserting the pile into the hole, has not been developed so far. It can be said that particularly ideal equipment has rarely been provided, and the work is generally done using a crane, etc., and the wire is wrapped around the pile and then attached to the hook part of the wire suspended from the crane. It was simply something that could be hung up.

However, with this conventional method, not only is it complicated to hang the wire, but it is also difficult to lift it in a predetermined position, even vertically, and it is also difficult to remove the wire after it has been moved to a predetermined position. For example, after inserting a pile into a pile hole, when removing the wire wrapped around the pile, the wire gets blocked by the cement milk filled in the gauging tube and cannot be removed properly, leaving the worker covered in mud. However, if the wire is still not removed properly, use a crane to forcefully pull the wire, and the pile will be pulled up to the deepest part of the pile hole, and the lower end of the pile will be pulled up. Cement milk got into the following parts, and the pile that was supposed to be buried at a predetermined depth was
In extreme cases, this can lead to work errors that directly affect work efficiency, such as having to redo the work, and there are also many safety issues. They were forced to continue working with problems.

This invention was developed by focusing on the current situation and continuing development and research by making use of our many years of experience as a civil engineering contractor.As a result, we have created a pile hanging device with a novel structure as detailed below. We have now seen the completion of the project.

(Structure of the Invention) As can be clearly understood from the representative embodiments shown in the drawings, the pile hanging device of the present invention includes a weight-shaped device body 1 whose bottom part is tapered. , a built-in space 2 is formed by vertically cutting in the central part including the axis, and a pair of eccentric rocking pieces 3.3 are arranged symmetrically in the built-in space 2, and a common shaft member 4 is used. A cable connection piece 31.31 for operation is formed on the upper surface of the eccentric rocking piece 3.3 near the tip thereof, and a hollow is formed at the upper end of the front and rear parts of the instrument body 1 that sandwich the built-in space 2. Hole 51.5
1 is formed so as to project upward, and is hung so as to cross the hanging pieces 5, 5 below the hollowed holes 51.51 of the hanging pieces 5, 5. It has a structure in which the spanning board 6 is integrated.

The lower part of the instrument body 1 is formed into a hemispherical shape as shown in the perspective view of FIG. 1 and the left side view of FIG. 3, or an inverted truncated conical shape (not shown). It is shaped so that when it is inserted from above the hollow part of the pile P, it is guided smoothly without getting caught inadvertently around the same place, and the overall shape is weight-like. It is made of iron material.

The eccentric rocking piece 3 is disposed in the built-in space 2 that is formed by vertically cutting the central part of the instrument body 1 including the axis line, and is symmetrical with a common shaft 4 in between. When the pair of parts are combined and rotated using the shaft member 4 as the rotation axis, they rotate eccentrically (that is, the distance from the shaft member 4 to the peripheral edge 33 varies from above to below the peripheral edge 33). (See FIG. 1 and FIG. 5, which are cross-sectional views illustrating the state of use.)

In addition, in order to increase the friction against the inner wall of the pile P, the peripheral edge 33 is desirably formed into an uneven shape as shown in the figure. The eccentric rocking piece 3 is rotated upward (pile PI
*1 An operating cable connection piece 31 is formed to connect the cable 8 to release the clinging to the FI wall.

In the figure, 32 indicates a through hole through which the cable 8 is inserted.

The hanging plate 6 has hollow holes 5 in hanging pieces 5, 5 which will be described later.
1, it is integrally horizontally installed on the upper surface of the instrument body 1 in such a manner that it intersects with the hanging piece 5.5, and is placed on the upper end of the pile P as shown in the fourth factor diagram Place,
It prevents the entire device from falling into the hollow portion of the pile P, and also functions as an adjustment plate to adjust the entire device to be located at the center of the hollow portion of the pile P.

The hanging pieces 5 protrude from the center of the upper surface of the device body located on both sides of the built-in space 2 to form a pair, each having a hollow hole 51, 51 formed therein, and a lifting cable 7 connected thereto. The hook 9 is suspended from a pulley or crane.

In order to increase the integration of the hanging piece 5 with the instrument main body 1, it is desirable that the hanging piece 5 be formed in the following horizontal configuration.

(Embodiment 1) As can be understood from the perspective view shown in FIG. 1, in which the hanging plate 6 is omitted, the instrument body 1 is located in a state where the built-in space 2 is sandwiched therebetween. The lower end side of the hanging piece 5 has a plug-in shape, and is combined so as to have a structure similar to that of a plant, and is integrated by welding 53 over the entire circumference of the boundary part with the instrument body 1. In this way, the integration between the hanging piece 5 and the appliance main body 1, which is the most burdensome part, is strengthened when lifting the pile P.

As shown in FIG. 6, a side view including a partial cross section for explaining the state of use, the bail hanging device of the present invention, which is constructed of the above-mentioned 'lR construction, has a hook portion 9 suspended therein. The device of the present invention, which is fitted into the hollow part of the pile P by being locked to the rope 7, bites into the pile P at the same place, suspends the pile P almost vertically, and inserts it into a predetermined pile hole. Move and insert into H.

The attachment structure of the pile P and the device of the present invention at this time is shown in the plan view shown in FIG. 4 showing the used state and the longitudinal sectional view shown in FIG. 5 in the used state. As can be seen from these drawings, the eccentric rocking piece 3.3 of the device of the present invention, which is fixed at the upper end position of the pile P by the spanning plate 6,
When the pile P rotates to its maximum extent until it reaches the inner wall of the pile P and tries to slide down, the rocking piece 3 that is in contact with the inner wall of the pile P
．． 3 is rotated further downward. As a result, the length of the eccentric oscillating piece 3 is forced to further increase a part of the stroke, and the device of the present invention is forced to further increase the stroke of a part of the pile P.
This strengthens the integral relationship with the pile P, thereby preventing the pile P from detaching or falling, and it becomes possible to reliably suspend and move the pile P using the device of the present invention.

When the pile P has been inserted into the predetermined pile hole H, the eccentric swinging piece 3.3 is rotated upward by pulling the operating cable 8, so that the same side edge 33 is inside the pile P. The device of the present invention can be removed from the pile P by being freed from sticking to the wall.

(Operation and Effect) The pile hanging device of the present invention having the above-mentioned configuration has a weight-shaped device body 1 having a unique shape with a tapered bottom and a built-in space 2 in the center. It has a structure that combines a swinging piece 3.3, a hanging piece 5.5, and a spanning piece 6, and the overall balance is good and it is easy to handle, and it is said that it is easy to fit into and remove from the pile P. It has major features and guarantees efficiency and safety of pile embedding work.

On the other hand, since the structure is generally simple, it is easy to manufacture and is difficult to damage even in environments where there is a lot of rough work such as construction sites. The equipment itself can be provided economically, and in combination with the above-mentioned economic efficiency, it is expected that the economic effect on the pile embedding work will be immeasurable.

In particular, in the case where the hanging piece 5.5 is planted in the apparatus main body 1, it is possible to lift a heavy pile P and strengthen the part where the load is concentrated. It can withstand long-term use, is more economical, and has higher safety.

As shown in the above, this invention is extremely effective in increasing the efficiency and ensuring safety of lifting and moving piles, and is also economical, so it is suitable for burying piles for ground reinforcement. It will be highly appreciated by those who work in the field.
