Description

本発明は、鋼管矢板等の杭を地盤に圧入する場合に前記杭を圧入する地盤の支持力を測定したり、支持力をリアルタイムで記録、管理することができる油圧圧入機支持力測定装置に関する。   [Technical Field] The present invention relates to a hydraulic press machine supporting force measuring device capable of measuring the supporting force of the ground for press-fitting the pile when pressing a pile such as a steel pipe sheet pile into the ground, and recording and managing the supporting force in real time. .

建設現場の基礎工事等においては鋼管矢板等の杭を地盤に圧入する場合、建造物の安全性等の見地から地盤の支持力が重要なポイントになる。
このため、従来においては鋼管矢板等の杭を杭圧入機等で圧入した後に、載荷試験装置を使用して載荷試験等を行って地盤の支持力を測定、記録等している（特許文献１）。
従って、鋼管矢板等の杭の圧入作業を行った後に圧入した杭の載荷試験を別途に行うため、杭の圧入作業と載荷試験作業が別途になって作業効率が悪いという不具合がある。
また、従来においては上述したように鋼管矢板等の杭を杭圧入機等で圧入した後に、圧入した杭の載荷試験等を行っていたので、杭を圧入する場合にリアルタイムで地盤の支持力を測定したり記録等したりすることができなかった。 In foundation work at a construction site, when a pile such as a steel pipe sheet pile is press-fitted into the ground, the supporting force of the ground is an important point from the viewpoint of the safety of the building.
For this reason, in the past, after a pile such as a steel pipe sheet pile is press-fitted with a pile press-fitting machine or the like, a loading test or the like is performed using a loading test device to measure and record the bearing capacity of the ground (Patent Document 1). ).
Therefore, since the loading test of the pile which was press-fitted after the press-fitting work of the pile such as the steel pipe sheet pile is separately performed, there is a problem that the press-fitting work and the load test work of the pile are separately performed and work efficiency is poor.
In addition, in the past, since a pile test such as a steel pipe sheet pile was press-fitted with a pile press-fitting machine or the like as described above, a load test of the press-fitted pile was performed. It was not possible to measure or record.

Needless to say, the pressure transducer mounting body 36 of the press-fitting machine supporting force measuring devices 34 and 50 may be attached to a place other than the first jack hydraulic hose 30 as long as it is a hydraulic circuit of the hydraulic jack device 18.
In the first embodiment and the second embodiment, the case where the steel pipe sheet pile 1 is press-fitted into the ground 2 has been described as an example, but the pile to be press-fitted is not limited to the steel pipe sheet pile 1 as a matter of course.

なお、測定した圧力の値は図５に示すようにグラフで表示するようにしてもよく、実施例で示す場合に限定されるものでないことは勿論である。   The measured pressure value may be displayed in a graph as shown in FIG. 5, and is not limited to the case shown in the embodiment.

本発明の油圧圧入機支持力測定装置３４，５０は鋼管矢板１を圧入する場合だけでなく他の杭を圧入する場合にも使用することができる。   The hydraulic presser support force measuring devices 34 and 50 of the present invention can be used not only when the steel pipe sheet pile 1 is press-fitted but also when other piles are press-fitted.
