Description

Technical Field

[0001] This utility model relates to a tunnel secondary lining maintenance trolley, and in particular to a tunnel secondary lining surface water heating atomizing spray maintenance trolley. Background Technology

[0002] Currently, after the tunnel secondary lining construction is completed, the secondary lining surface is sprayed with water for moisturizing and curing by manual operation using a curing trolley. Conventional secondary lining surface curing uses normal temperature water spraying. When the tunnel is in a low temperature environment, the sprayed water quickly cools down to low temperature water, resulting in a decrease in the temperature of the secondary lining surface, poor solidification effect, and affecting the construction quality and progress. In view of the above reasons, a tunnel secondary lining surface water heating atomization spray curing trolley is proposed. Utility Model Content

[0003] The purpose of this invention is to overcome the problem that when manual operation of a tunnel secondary lining curing trolley for water spraying and moisturizing curing is carried out in a low-temperature environment, the low-temperature water causes the temperature of the secondary lining surface to drop, resulting in poor solidification and affecting the construction quality and progress. Through reasonable design, this invention provides a water-heated atomizing spray curing trolley for tunnel secondary lining. When performing curing work on the secondary lining surface in a low-temperature environment inside the tunnel, this invention provides heated water through a heated water storage tank. The heated water is atomized through an atomizing ring nozzle. Driven by an atomizing trolley, the atomizing ring nozzle provides comprehensive and uniform heating and moisturizing curing of the secondary lining surface, preventing temperature drop, accelerating the solidification effect, and improving construction quality and progress.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: A water-heated atomizing spray curing trolley for tunnel secondary lining is composed of: a temperature-controlled atomizing curing trolley, an atomizing annular spray pipe, a heating water tank, a water pump, a water pressure pipe, a water pressure telescopic pipe, atomizing nozzles, an annular pipe bracket, a gantry, a top frame, an atomizing trolley, trolley tracks, a traveling mechanism, and a bottom beam; a pair of gantry frames are installed at both ends of the temperature-controlled atomizing curing trolley, a pair of bottom beams are installed at the lower ends of both sides of the gantry frames, and a pair of traveling mechanisms are installed at both ends of the bottom beams, which are used to drive the temperature-controlled atomizing curing trolley; a top frame is installed at the upper end of the gantry frames, a pair of trolley tracks are installed on both sides of the middle of the top frame, an atomizing trolley is installed on the trolley tracks, an annular pipe bracket is installed above the atomizing trolley, an atomizing annular spray pipe is installed on the outer side of the annular pipe bracket, and atomizing nozzles are evenly distributed on the outer side of the annular spray pipe, with the angle of the atomizing nozzles corresponding to the tunnel wall; the atomizing trolley is used to drive the annular spray pipe to run along the trolley tracks.

[0005] A heating water tank is installed in the middle of the bottom beam on one side. The heating water tank is used for water heating in low-temperature construction environments. A water pump is installed in the heating water tank. A water pressure pipe is installed at the drain end of the water pump. A water pressure telescopic pipe is installed between the water pressure pipe and the inlet of the atomizing ring nozzle. The water pressure telescopic pipe is used for moving the atomizing ring nozzle.

[0006] Beneficial effects: When performing curing work on the secondary lining surface in a low-temperature environment inside a tunnel using the heating and atomizing spray curing trolley of this utility model, heated water can be provided through a heated water storage tank. The heated water is atomized by atomizing nozzles through an atomizing ring spray pipe. The atomizing trolley drives the atomizing ring spray pipe to comprehensively and evenly heat and moisturize the secondary lining surface, which can prevent the temperature of the secondary lining surface from dropping, accelerate the solidification effect of the secondary lining surface, and improve the construction quality and progress.

[0007] 1. Constant temperature and humidity control: The temperature and humidity environment of the secondary lining surface is maintained by heating water atomization. Hot water atomization accelerates the hydration and penetration reaction of concrete, shortens the curing cycle, improves the strength of the secondary lining, and reduces the risk of drying shrinkage cracking.

[0008] 2. Automatic spray curing: A ring-shaped longitudinal pipeline is used to cover the tunnel sidewalls and arch area to ensure uniform curing.

[0009] 3. Switching between heating water and steam: The heating water tank and the steam generator are connected in series with the pipeline system, which can switch between water and steam. When high temperature is required, the pipeline system switches to steam to steam the tunnel face for steam curing. Attached Figure Description
