CONSTITUTION:A pile receiving guide 11 is provided in a lower end of a leader 10 for driving a pile 2 diagonally with a pile hammer 9, and the pile 2 is hanged down by a wire 14. Next, a pile driver 7 is guided to a predetermined position, and the wire 2 is relaxed to ground the pile 2. Positioning of the pile 2 is performed without an auxiliary crane, and the pile 2 is driven with the pile hammer 9. The working efficiency is thereby improved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for driving a diagonal shaft on land using a three-point support type pile driver.

[Conventional technology]

Conventionally, when driving an inclined shaft on land, as shown in Fig. 6, a conductor 1 made of H-beam steel or the like is installed at a predetermined position on the ground G for pile driving, and an auxiliary crane (not shown) is installed. The pile 2 to be used for driving is placed along the diagonal leader 3, the lower end of the pile 2 is manually set at the predetermined position for pile driving, and the guiding material 1 is placed along the diagonal leader 3.
After removing the pile, the pile 2 was driven using a hammer 4.

However, according to the above conventional method, manual work is required to install and remove the conductive material 1, to align the resistor 2 to be cast along the leader 3, and to position the resistor 2 to be cast. However, there was a problem that the work efficiency was poor.

[Problem to be solved by the invention]

The present invention has been made in order to solve the above-mentioned conventional problems, and aims to provide a method for driving an inclined shaft on land using a three-point support type pile driver, which is more efficient than the conventional method. This is a problem to be solved.

[Means to solve the problem]

As a means to solve the above-mentioned problems, the method for driving a slanted shaft according to the present invention provides a method for driving a sloped shaft at the lower part of the hammer of a three-point support type pile driver.
The lower end of the pile is suspended by a wire connected to a hanging ring installed at the center of the upper surface of the pile through a hook attached to the center of one side of the pile, and attached to the lower end of the leader of the three-point support type pile driver described in -F. With the pile support along the guide, guide the three-point pile driver to the specified position for driving the pile, then loosen the wire and ground the bottom end of the pile at the specified position for driving the pile. After that, the piles are driven using a hammer.

This method does not require an auxiliary crane as in the past, and also eliminates inefficient manual labor such as manually setting the upper end of the pile to be driven into a predetermined position.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the work of driving an inclined shaft on land by applying the driving method of the present invention will be described below with reference to the drawings.

First, the three-point support type pile driver 7 shown in FIG. A diesel pile hammer 9 is attached to the center of the top surface of the leader 10.

Next, at the lower end of this leader 10, a guide 11 is provided for the pile support shown in FIGS. 2 and 3, and at the center of the upper surface of the lower part of the diesel pile hammer 9, as shown in FIG. A hook 12 is attached, and a hanging ring 13 is further provided at the center of the upper surface of the upper part of the pile 2 to be driven.

Therefore, as shown in Figs. 4 and 5, the diagonal slider 10
The wire 14 shown in FIG. With the pile 2 suspended as shown in FIG.

In addition, in FIGS. 4 and 5, the part not shown by 15 is a pile cap.

Next, the three-point support type pile driver 7 in this state is moved on the ground G, rotated, and guided to a predetermined position where the pile 2 is to be driven.

Then, the wire 14 suspending the pile 2 is loosened, and the lower end of the pile 2 is grounded at a predetermined position on the ground G where it will be driven.

Thereafter, the guide 11 of the pile receiver is removed in the direction of arrow R in FIG. 2, and the pile 2 is driven in with a diesel pile hammer 9.

The structure of the bearing guide 11 in this embodiment is as follows:
As shown in FIGS. 2 and 3, the reader 10 can be rotated in the direction of arrow R with respect to the lower end of the leader 10 via a hinge 21, and can be attached and detached using a pin 20 and a hinge 22. If the rigidity is increased, the leader 1
It can also be fixedly provided at the lower end of 0.

・As shown in Figures 4 and 5,
The hanging ring 13 provided on the diesel pile hammer 9 and the hook 12 attached to the diesel pile hammer 9 are both positioned at the center of each upper surface, that is, on the center line of the upper surface relative to the slope, so that the three-point support type pile driver 7 wire 14
If the pile 2 is connected to the hanging ring 13 of the pile 2 to be driven through the hook 12 of the diesel pile hammer 9 and suspended, the pile 2 will be smoothly and accurately accommodated in the pile camp 15, so that no auxiliary crane is required.

〔Effect of the invention〕

According to the method for driving an inclined shaft of the present invention described above, the pile can be efficiently aligned with the leader of the three-point support type pile driver without using an auxiliary crane as in the conventional method.

In addition, the three-point support type pile driver can be moved and rotated to guide the pile to the designated position while the pile is aligned with the leader.
This has the effect that the positioning work of the piles to be driven can be done efficiently without manual intervention.

Furthermore, the method of the present invention does not require installing conductive material on the ground as in the conventional method, so it is economical and
This has the advantage that the work of installing and removing the conductive material can be saved.
