Description

  The present invention relates to a pile driving monitoring system used when a pile is driven into the ground by a pile driving machine.

  Foundation piles (hereinafter simply referred to as “pile”) constructed in civil engineering foundation work are driven using a pile driver such as a three-point pile driver. On the other hand, it must be driven at a predetermined angle. Therefore, during the construction, the driving angle of the pile is always measured, and the driving angle is corrected appropriately.

  By the way, this pile driving machine is provided with a leader that can be raised and lowered on the front surface of a pile driving machine main body having a driving operation room as shown in Patent Document 1, for example, on the front surface of this leader, for example, an auger and The structure is such that a hydraulic hammer or the like can be attached to be movable up and down.

  When this pile driver is used at the construction site, for example, the auger is attached to the leader of this pile driver and is raised, while a large crane is used to insert a screw for excavation into the hollow portion of the hollow steel pipe pile. Then, the steel pipe pile is pushed into the ground by driving the auger and excavating the ground with a screw to drive the pile into the ground.

  When driving piles with such a pile driver, measurement and management of the pile angle has conventionally been done by placing construction managers at two points slightly away from this pile driver, and managing the construction at each point. The operator measures the pile angle with transit etc. and monitors whether there is any deviation from the predetermined driving angle, and if the correction is necessary, the construction manager operates the pile driver. Signals and instructions were given to the operator, and the operator of the pile driver received instructions from the construction manager and operated the pile driver to correct the pile driving angle appropriately.

  This is because there is a large leader on the front of the driver's operation room of this pile driver, so the view from the operator's room is extremely bad, and earth and sand are scattered on the window of the operator's room during work. The visibility may be further deteriorated, and therefore it is difficult for the operator to confirm the situation by directly viewing the driving angle of the pile during the driving operation.

  Therefore, the conventional method in which the operator corrects the driving angle of the pile according to the instruction of the construction manager is time-consuming and inefficient, and it is difficult to make a reliable correction, and a more appropriate method is required. Yes.

  The present invention enables the operator of the pile driving machine to check the driving angle of the pile, so that the driving operation of the pile can be performed quickly and safely and the labor saving of the driving operation of the pile can be achieved. A pile driving monitoring system is provided.
