Title:
INJECTION EXECUTION AND INJECTION DEVICE
Document Type and Number:
Japanese Patent JP3418069
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an injection execution and an injection device in which an impregnating agent is fed through a liquid feed pipe from a storage tank and into a desired one of injection holes formed in the ground to be impregnated so as to continuously carry out injection under selection management of an impregnating hole.
SOLUTION: A plurality of impregnating holes N1 to Nn formed in the ground 1 to be impregnated, are communicated with a storage tank T through liquid feed pipes 2 each incorporating an injection pump P and a flow measuring device F as necessary, respectively, and valves V1 to Vn are connected in the pipes n1 to Nn, down stream of the injection pump P and near the holes N1 to Nn, respectively. The injection pump P is connected to a controller 3 for controlling the operation of the injection pump P, and the flow measuring device F is connected as necessary to the controller 3 for controlling the device F in order to control the flow rates of the impregnating agent. Thereby it is possible to continuously feed the impregnating agent from the tank T into a desired one of the holes through the associated feed pipe 2.
