A pressure chamber is formed in a pressure container. A discharge flow path is formed in the outlet pipe. A conveyance flow path is formed in the conveyance hose. An injection hole is formed in the nozzle. The discharge flow path goes from the pressure chamber to the outside of the pressure container. The conveyance flow path is communicated with the discharge flow path. The injection hole is communicated with the conveyance flow path. When dilatable vermiculite is injected, the supply mechanism supplies force-fed gas to the pressure chamber. |
