Abstract: The present application relates to tunnel monitoring and measuring, more particularly, to a quick fixing device for measuring a tunnel peripheral convergence and an application method thereof. A right-angle steel sheet includes a first steel sheet and a second steel sheet which are vertically fixed with each other. The fastener vertically penetrates the first steel sheet, and an explosive powder loading portion on a rear end of the fastener is arranged at a side of the second steel sheet. The reinforcing steel sheet is respectively connected to the first steel sheet and the second steel sheet as a reinforcing bar. A through hole is provided on the reinforcing spacer, through which the reinforcing spacer is sleeved on the fastener. The reinforcing spacer is arranged between the explosive powder loading portion on the rear end of the fastener and the first steel sheet.

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.
