Abstract
A pile press-in machine that receives reaction force from an existing pile to press in a new pile, includes: a reaction force block that grips the existing pile by a clamp to receive the reaction force; a platform that is horizontally movable relative to the reaction force block; and a press-in block that is coupled to the platform, supported to be freely lifted up and down with respect to the platform at a front of the clamp, and grips and presses in the new pile, wherein a plurality of kinds of the reaction force blocks each according to a kind and size of the existing pile are freely attachable to and detachable from one platform.
Claims15
A pile press-in machine that receives reaction force from an existing pile to press in a new pile, the pile press-in machine comprising:
- a platform configured to receive at least one of a plurality of reaction force blocks and a press-in block, wherein a first reaction force block of the plurality of reaction force blocks is configured for use with the existing pile and at least one other reaction force blocks of the plurality of reaction force blocks is configured for use with a pile having a different shape than the existing pile, the plurality of reaction force blocks each including a reaction force block coupling, the reaction force block couplings configured to be selectively, removably coupled to the platform;
- and
- a press-in block coupled to the platform and supported to be freely lifted up and down with respect to the platform to press in the new pile,
- wherein the reaction force blocks are horizontally moveable relative to the platform during attachment and detachment,
- wherein each of the reaction force block couplings includes a slide guide that is configured to slidably couple to a slide frame on the platform, and
- wherein the slide guides of the plurality of reaction force blocks are identical.
A pile press-in method using a pile press-in machine, the pile press-in machine comprising:
- a first reaction force block that is configured to grip an existing pile having a first shape by a clamp to receive reaction force;
- a platform that is horizontally movable relative to the reaction force block;
- and
- a press-in block that is coupled to the platform, supported to be freely lifted up and down with respect to the platform at a front of the clamp, and is configured to grip and press in the new pile,
- wherein the first reaction force block is removable from the platform and replaceable with a second reaction force block according to a different shape and size of a pile than the existing pile, wherein the first and second reaction force blocks include a unified coupling configuration that allows the first and second reaction force blocks to be freely attachable to and detachable from the platform, wherein the unified coupling configuration includes a slide guide that is configured to slidable couple to a slide frame on the platform, and
- wherein the method comprises selecting one of the first and second reaction force blocks and slidably coupling the reaction block to the platform.
A pile press-in machine comprising:
- a first reaction force block that comprises a first grip configured to grip a first existing pile;
- a second reaction force block that comprises a second grip configured to grip a second pile having a different shape than the first existing pile;
- a platform having a slide frame;
- and a first press-in block comprising a first chuck configured to chuck a first new pile, a first size of the first existing pile and the first new pile is the same;
- wherein
- the first reaction force block is detachably attachable to the platform, wherein the first reaction force block includes a slide guide that slidably couples to the slide frame on the platform;
- the first press-in block is detachably attachable to the platform;
- the second reaction force block is detachably attachable to the platform and exchangeable with the first reaction force block;
- the first reaction force block is movable horizontally relative to the platform when the first reaction force block is attached to the platform;
- and
- the first press-in block is movable vertically when the first press-in block is attached to the platform.
