Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of press-fitting a pile, which is capable of quickly and efficiently constructing a pile row made of copper sheet pile or the like.

[0002]

2. Description of the Related Art Conventionally, when constructing a pile row in a narrow area or on the water, piles are stored at an initial work point and are put on standby by a crane truck for loading and unloading piles as needed. It was loaded on a ship or carrier and transported to the site. Then, the transported piles were transferred to the self-propelled pile press-in / pull-out machine using the on-board crane or the self-propelled crane on piles at the site and press-fitted.

[0003]

However, such a conventional method requires a large area for storage of piles and also requires a crane vehicle for loading and unloading piles to be always on standby, which increases manpower and costs. Becomes Securing a waiting place for crane trucks and a work site is also a problem. Further, as the pile row progresses, the storage place of the press-fitting piles and the press-fitting site are far away from each other, so that the transportation time by the ship or the transportation device becomes long and the workability deteriorates.

The present invention has been made in consideration of the above circumstances, and provides a method for press-fitting a pile that enables labor-saving and speed-up by enabling efficient transport of the press-fitting pile. With the goal.

[0005]

According to a method of press-fitting a pile of the present invention, a pile for press-fitting is loaded on a loading table provided on an existing pile row, and the pile is picked up by a loading device provided on the existing pile row. And then load it onto a carrier that travels over the existing row of piles, then
Travel the carrier to the press-fitting site, and transfer the press-fitting pile from the carrier to the self-propelled pile press-fitting / extracting machine at the press-fitting site, or by using the press-fitting / extracting machine with a crane. Characterized by direct intake and press fitting.

[0006]

[Operation] Since the press-fitting piles are stored in the loading platform provided in the existing pile row, the storage site on the ground is unnecessary. The loading device picks up piles from this loading platform and loads them into the transporter, and the transporter travels over the existing pile rows and transports them to the press-fitting site, so transporting the piles regardless of the narrow area or water. Can be done. Further, by changing the installation location of the loading platform and the loading device as the pile row progresses, the transportation distance can be shortened and quick press-fitting can be performed.

As shown in FIGS. 1 and 2, on the existing row of piles,
A rail 50 of the same type as the pile P is laid, and a carrier 51 is installed on the rail 50. This carrier machine 51 is for self-propelled on the rail 50 and carries the pile P on the carriage 51a.

The above-mentioned FIGS. 1 to 3 show the press-fitting pile P.
It shows a portion for loading and storing n, and a self-propelled pile press-in / pull-out machine and a crane (both not shown) that are self-propelled on the existing pile row 1 are arranged at the forward end of the existing pile row 1. There is. Since these self-propelled pile press-in / pull-out machines and cranes can have a conventionally known structure, description thereof will be omitted.

Next, an embodiment of the present invention using the above configuration will be described. First, as shown in FIGS. 1, 2 and 3, the press-fitting piles Pn transported to the site by a truck or the like are stocked on the necessary number of loading platforms 2. In addition, the press-fitting pile Pn is used for the loading table 5
When loading and unloading to the second position, the pile P does not hit the boom 20 if the position of the boom 20 is turned 90 degrees or more from the position of FIG. After that, the press-fitting pile Pn is carried by the carriage 51a of the transport note 51.
To load. At that time, first, the traveling motor is driven to drive the front wheels 37 to move the loading device 30 to a position directly above the pile Pn on the loading platform 2, and the cylinder 39 is extended to lower the holding body 31. At the same time, the cylinder 32 of the holding body 31 is operated to open and close the holding claws 31a and 31a, and the pile P
n is sandwiched. Then, the cylinder 39 is operated to raise the holding body 31. Next, the front wheel 37 is driven to drive the holding body 3
