Abstract
PURPOSE: To provide a construction method which enables a concurrent improvement even when ground areas for improvement are scattered over an extensive zone by dispensing a cooling water at time of boring and a chemical solution for improvement from each one of the tanks to a plural number of excavation/injection devices.
CONSTITUTION: A chemical solution H is dispensed in parallel to a plural number of excavation/injection devices C from a tank 1 through the intermediary of a dispensing system L equipped with distributing valves 5, 6 halfway. At the same time, cooling and lubricating water (d) is supplied in parallel to each excavation/injection device C from the dispensing system L through the intermediary of distributing valves 20, 23, 24 at time of boring prior to the dispensing of the chemical solution.
