the seismic reinforcing steel insertable type jet grouting structure and the construction method thereof

摘要

According to the present invention, provided are a jet grouting structure embedding seismic reinforcing steel thereinto, and a construction method thereof. The present invention can spray grout (G) to an excavation hole of the ground (100) to insert the steel (200) to the hole. An upper end of the steel (200) is coupled to be a head cap (300) to be lifted. A lower end of the steel (200) is vertically lowered by a guide cage (400). Moreover, the steel (200) is embedded into the grout (G).
