## Abstract

Provided is a rescue capsule for shelter in tunnel construction, relating to lifesaving equipment. The rescue capsule includes a housing. A cavity of the housing includes an equipment compartment which is located at an upper portion of the cavity and a passenger compartment which is located at a lower portion of the cavity. An exterior of the housing is provided with an external skeleton. The exterior of the housing is further provided with an external indicating sign and an external rescue indicator. The housing is further provided with an explosion-proof sealing door. An oxygen cylinder, a power supply, a maintenance box, a first air purifier and a medical box are provided in the equipment compartment. Areas where the maintenance box and the medical box of the equipment compartment are provided communicate with the passenger compartment.
