Description

  The present invention relates to a press-fitting system for piles. More specifically, a complicated chucking process is unnecessary, the press-fitting process of the parent pile can be simplified, work efficiency can be improved, and there is a problem of bending and deformation of the parent pile. This is a pile press-in system that does not occur, and relates to a pile press-in system suitable for shape steel press-in work in, for example, mountain construction using the parent pile sheet pile method.

  An example of a construction method belonging to the type of the conventional pile pile sheet pile construction method will be outlined with reference to FIG.

  In the conventional parent pile horizontal sheet pile method, first, a temporary pile 81 is driven into a predetermined location of a mountain retaining work site, and then a first pile used as a parent pile for mountain retaining work using a work machine 71 such as a hydraulic excavator. The H-shaped steel 61 is suspended and built in the target location.

  Next, a winch unit 53 having a chuck 54 is used at a lower end portion attached to an arm 52 in a press-fitting machine 51 such as a silent pillar, and the pile head of the temporary pile 81 is chucked by the chuck 54 and the wire of the winch unit 53 is used. 55 is in tension.

  That is, the arm 52 is fixed and can withstand a reaction force generated when the first H-shaped steel 61 is press-fitted.

  Next, the press contact body 57 disposed at the lower end portion of the press-fit cylinder unit 56 provided in parallel with the winch unit 53 with respect to the arm 52 is pressed against the pile head of the first H-section steel 61, and this state Then, the press-fitting cylinder unit 56 is operated to press-fit the H-shaped steel 61 to the target position.

  Even when the second and subsequent H-section steels 61 are press-fitted, the press-fitting process of each H-section steel 61 is performed while performing the same chucking operation as described above.

  However, in the case of such a parent pile sheet pile method, a complicated chucking operation is required every time the H-shaped steel 61 is press-fitted, and the work efficiency is not good.

  Moreover, the H-section steel 61 used as the parent pile in the parent pile sheet pile method often uses a steel material of a normal width series (for example, 200 × 100 mm or 200 × 150 mm).

  This is because the purpose of mountain construction is to create a wall that can withstand lateral pressure.

  In this case, in the parent pile sheet pile method as described above, since the narrow part of the H-section steel 61 that is the parent pile comes in the traveling direction of the press-fitting machine 51, the pressure is applied to the H-section steel 61 to be press-fitted (for example, the second one). In many cases, the H-shaped steel 61 being chucked (for example, the first one) is bent (tilted from the vertical direction) or deformed.

  In Patent Document 1, a press-fitting cylinder unit having a press-contact body, which presses against a pile head of a pile, is positioned at the front side with respect to a tip end side of an arm projecting so as to swing up and down from the machine body side of the construction machine. A pile press-fitting device is disclosed in which a winch unit with a chuck for gripping a pile head of the pile is arranged in an arrangement in front of the pile unit.

  However, in the case of the press-fitting device for a pile of Patent Document 1, as in the case of the above-described conventional example, a complicated chucking operation is required, and the problem of bending or deformation of the chucked parent steel is included. .
