Manufacture method of quick and slow setting grouting components to prevent leaching of liquid type which can automatically control to gel time and construction methods

摘要

The present invention is to prepare a solution-type grouting composition capable of providing rapid setting and completion of gelation time control and dissolution prevention using silicate and polymeric monomer, initiator, crosslinking agent, and crosslinking accelerating catalyst, controlling gelation time and preventing dissolution of grouting. In step (A) of producing the silica sol of the grouting material required, the inflow amount of the polymeric monomer containing water-soluble silicate, acid, and initiator is controlled by the fluid automatic inflow control device, and the strength is increased and In step (B), which is added for acceleration, delay of gelation, and crosslinking of polymeric monomers, a solution-type grouting injection material for rapid setting gelling in 4-15 seconds or gelling in 45-80 seconds can be provided, in which case The incoming material is mixed with water, and through the mixing step of uniformly mixing the drug A and the drug B formed in each step, the gelation step and the solidification step that the gel time can be automatically controlled through the injection step, the grouting injection material for preventing leaching It has a feature that can provide a grouting injection material that can be uniformly and efficiently formed on the order wall with the purpose of ordering without mobilizing a lot of manpower during grouting, regardless of the shape of the soft ground. It is characterized by having.
