摘要： PROBLEM TO BE SOLVED: To provide a pump pulsation interlocking accelerating agent supply system, capable of adjusting the accelerating agent supply timing, by observing a timing lag between pulsation of a concrete pump and pulsation of jetting concrete of a tip nozzle, in response to a construction condition and a construction state of a job site.
SOLUTION: This pump pulsation interlocking accelerating agent supply system has a switching starting signal detecting part 2f for detecting a suction and delivery switching signal of the concrete pump 2, a remote control part 30 for inputting and setting synchronous adjusting time of stopping and starting supply of an accelerating agent by synchronizing with concrete supply pulsation generated by switching a delivery cylinder of the concrete pump 2, and a synchronous control device 10 for outputting a supply stopping and supply starting signal of the accelerating agent to an accelerating agent supply device by calculating synchronous adjusting time T2 by a synchronous adjusting instruction inputted and set from the remote control part 30 by receiving a signal from the switching starting signal detecting part 2f. The system is characterized by controlling delivery of the accelerating agent so as to synchronize with pulsation of concrete supplied to the tip of the nozzle 20.

摘要： PROBLEM TO BE SOLVED: To provide a driving tool which is improved in the discharge efficiency of excavation chips, and to provide a steel pipe driving method which is high in efficiency, low in cost, and positively prevents the formation of excessively loosening areas and cavities of the natural ground around a steel pipe by using the driving tool.
SOLUTION: The steel pipe driving tool is formed of a steel pipe c, a rod a inserted into the steel pipe c, and an excavation bit b attached to the front end of the rod a via a bit joint f. According to the structure of the steel pipe driving tool, a central passage α is secured in an inner pipe e of the rod a, an annular passage β is secured outside the inner pipe e, and a discharge passage γ is secured outside the rod a and the bit joint f. Further, the bit joint f forms a communication hole making a flushing hole 55 opened in the front surface of the bit b communicate with the central passage α of the rod a, and a reverse blow hole 50' communicating with the annular passage β and opened in the discharge passage γ in a diagonally rearward direction. The steel pipe driving method is implemented by using the steel pipe driving tool.
