Chemical liquid injection grouting process automation systems

摘要

The purpose of the present invention is to provide an automatic grouting system for a chemical feeding method capable of reducing a time required for injecting a grouting material into all injection holes and improving the economic efficiency of grouting by closing passages according to an order of injection pipes where injecting the grouting material is completed and enabling an amount of the grouting material corresponding to a surplus amount of the forcibly transferred grouting material to flow to the injection pipe in process of injection. To achieve the purpose, the automatic grouting system for a chemical feeding method according to the present invention includes: multiple forcibly-transferring devices absorbing an A solution and a B solution or a mixture thereof which are the grouting materials and forcibly transferring the same to the injection pipes; flow meters installed in forcibly-transferring pipes connected to outlets of each forcibly-transferring device; a hydraulic pump for driving the forcibly-transferring devices; electronic valves installed in each hydraulic branch pipe connected from the hydraulic pump to each forcibly-transferring device; and a data storing device storing data transmitted from the flow meters. The automatic grouting system for a chemical feeding method sets the maximum pressure of the flow meters and blocking the hydraulic branch pipe of the forcibly-transferring device belong to the corresponding injection pipe with the electronic valve based on signals received by the data storing device when a pressure measured by the flow meter reaches the maximum pressure to supply an amount of the grouting material corresponding to the surplus amount the forcibly transferred grouting material to other injection pipes in process of injection.
