Through the pipe quick connectors, connect the high-pressure pipes on the water spray pipe part 98 with the output pipes on the spraying device 4, connect the high-pressure pipes on the injection pipe part I 96 with the output pipes on the fog-making device 3, and connect the high-pressure pipes on the injection pipe part II 95 with the output pipes on the steam generator 2, so that the steam generator 2, the fog-making device 3 and the spraying device 4 are in working states. The high-pressure pump of the spraying device 4 conveys high-pressure water into the water spray pipe part 98, and the water spray hole body of the water spray pipe part 98 sprays out water bodies, and the tunnel secondary lining body is wetted by the sprayed water bodies. After the wetting treatment of the tunnel secondary lining body is completed, make the spraying device 4 in a non-working state. The fog-making device 3 conveys normal temperature water mist into the injection pipe part I 96, and the L-shaped channel of the injection pipe part I 96 sprays the normal temperature water mist towards the spherical part II 94. The steam generator 2 conveys high-temperature water steam into the injection pipe part II 95, and the L-shaped channel of the injection pipe part II 95 sprays the high-temperature water steam towards the spherical part II 94.

[0124] When verifying the present invention, the inventor discarded the prior art features that are only used for the construction of the second lining of the tunnel, resulting in the construction and maintenance of the second lining of the tunnel being in separate time periods. First, the technical feature of the linkage operation of the construction of the front-section tunnel second lining and the maintenance of the rear-section tunnel second lining in cold regions was proposed, obtaining the first unexpected technical effect: realizing the placement of the rear trolley components for the maintenance operation of the tunnel second lining, ensuring the vehicle passing performance required for the construction operation of the front-section tunnel second lining, and no longer occurring the interference phenomenon between the construction and maintenance operations of the tunnel second lining, obtaining the second unexpected technical effect: realizing the maintenance period based on the construction period of the tunnel second lining, improving the maintenance effect of the tunnel second lining, obtaining the third unexpected technical effect: realizing the maintenance sealing interval on the tunnel second lining by the support cover assembly 5, increasing the area of the maintenance sealing interval on the tunnel second lining, obtaining the fourth unexpected technical effect: realizing the end contact sealing of the tunnel second lining by the movable disk seat 55, the sealing strip 56 and the scissors lift 57, and improving the end sealing effect of the tunnel second lining under the power action of the telescopic cylinder I 575 and the telescopic cylinder II 576, obtaining the fifth unexpected technical effect: realizing the covering contact sealing of the tunnel second lining by the sealing film 58, the intermediate rod 59 and the hanging ring 50, and improving the support strength of the sealing film 58 and the covering sealing effect of the tunnel second lining under the hoisting action of the intermediate rod 59 and the hanging ring 50, obtaining the sixth unexpected technical effect: realizing the wetting treatment of the tunnel second lining by the spraying device 4 and the water spraying pipe part 98, realizing the upward spraying of water flow, and improving the wetting effect of the tunnel second lining, obtaining the sixth unexpected technical effect: realizing the release of a suitable temperature and high humidity maintenance medium gas into the maintenance sealing interval by the steam generator 2, the fog-making device 3, the cylinder shell part 97, the spraying pipe part I 96, the spraying pipe part II 95 and the spherical part II 94, preventing the occurrence of step-like temperature and humidity value changes, and meeting the maintenance factor requirements of the tunnel second lining in a construction site with an extreme temperature step difference, obtaining the seventh unexpected technical effect: realizing the docking of the support cover assembly 5 and the tunnel second lining trolley body 1 by the connecting rod 6, the ear seat 7 and the pin shaft 8, and realizing the adjustment of the distance between the support cover assembly 5 and the tunnel second lining trolley body 1 to meet the space requirements of the linkage operation of the construction and maintenance of the tunnel second lining.

[0125] In the second embodiment of the present invention, the tunnel second lining trolley body 1 and the rear trolley components are connected in accordance with the way of the linkage operation of the construction of the front-section tunnel second lining and the maintenance of the rear-section tunnel second lining in cold regions.

[0126] In this embodiment, the rear trolley component is connected to the tunnel secondary lining trolley body 1 in a follow-up maintenance manner for the tunnel secondary lining body at the construction site with the difference in extreme temperature steps after construction.

[0127] In this embodiment, the rear trolley component is provided to include a support cover assembly 5 and a nozzle assembly 9.

[0128] In this embodiment, it further includes a first accessory device, and the first accessory device is arranged between the rear trolley component and the tunnel secondary lining trolley body 1. The first accessory device is provided to include a steam generator 2, a fog-making device 3, and a spraying device 4.

[0129] In this embodiment, it further includes a second accessory device, and the second accessory device is arranged between the rear trolley component and the tunnel secondary lining trolley body 1. The second accessory device is provided to include a connecting rod 6, an ear seat 7, and a pin shaft 8.

[0130] The second embodiment of the present invention is based on the first embodiment. In the second embodiment of the present invention, the steps are as follows: The tunnel secondary lining trolley body 1 realizes the powered movement docking of the rear trolley component, and the rear trolley component realizes the follow-up maintenance of the tunnel secondary lining body at the construction site with the difference in extreme temperature steps after construction, realizing the linkage operation of the construction of the front-section tunnel secondary lining body and the maintenance of the rear-section tunnel secondary lining body in cold regions.

[0131] The second embodiment of the present invention is based on the first embodiment. The application process of the present invention: Currently, in the maintenance technical methods for tunnel secondary lining, generally there are wet maintenance by sprinkling water or combined with covering wet materials, maintenance by covering plastic film, and steam maintenance. Wet maintenance is more suitable for areas with moderate temperatures. In contrast, film maintenance and steam maintenance can provide a certain heat insulation environment, so they are more suitable for low-temperature or cold regions. However, only the steam generator is used for steam curing of the secondary lining concrete, and its humidity adjustment is relatively single. It may be difficult to keep the concrete surface evenly moist. Especially in large-area linings, steam is not easy to cover comprehensively, resulting in insufficient local maintenance. And it is easy to cause excessive energy waste. Especially in an environment with poor airtightness, steam is easy to escape, reducing the maintenance efficiency. With the expansion of the tunnel construction scope, in extreme environments such as plateaus, extremely cold regions, and arid areas, environmental problems such as water resource shortage, difficulty in maintaining temperature, and large temperature difference between day and night limit the maintenance effect, and the maintenance temperature and humidity cannot immediately meet the changes brought by the environment. This requires further improvement and innovation of maintenance technologies, especially the research and development of maintenance equipment and technologies suitable for these special environments.

[0132] The spraying and steam integrated curing trolley combines spraying with hot steam, significantly reducing the curing cost and energy waste. It can adapt to various complex tunnel environments, greatly improving the efficiency and accuracy of the curing operation, enhancing the efficiency and quality of the secondary lining curing of the tunnel, and providing a more energy-saving and environmentally friendly solution for tunnel engineering projects.

[0133] It consists of a main frame, a top extension system, and a walking system. The main frame is 12m long longitudinally, which is used to bear the self-weight of the trolley and serves as the installation platform for devices such as the electrothermal steam generation system, the spraying system, the water tank, and the sealing system. The top extension system supports the trolley to be sealed and extended to the surface of the secondary lining to form a tight sealed space. The walking mechanism consists of a speed reducer, an anti-sliding device, rubber tires, etc., providing the functions of the trolley moving forward, backward, and standing still.

[0134] It consists of end face radial sealing, bottom longitudinal sealing, and toroidal sealing. The end face radial sealing uses sponges (rectangular sponges + cylindrical sponges), which are fixed on the toroidal support of the trolley frame. During operation, it is closely attached to the surface of the lining concrete through the telescopic hydraulic cylinder. The connection of the arc-shaped frame of the filling layer adopts a hinged method, and the arc-shaped frames on both sides of the filling layer are telescoped by the cylinder. The bottom longitudinal sealing uses sponges of the same structure, which are fixed on the longitudinal support of the trolley frame and spread along the inner contour surface of the lining. The end is connected to the section sponge. The sponges for end face radial sealing and bottom longitudinal sealing are both wrapped with high-strength tensile fireproof steam sealing covers on the outside, which can ensure the service life of the sponges. The toroidal longitudinal sealing also uses high-strength tensile fireproof steam sealing covers, forming a sealed space for the lining concrete with a surface covered by a waterproof and heat-insulating composite material and the end sealed by sponges. The sealing system should ensure that the temperature fluctuation value ≤ ±2°C and the humidity fluctuation value ≤ ±5% during the constant temperature and humidity curing period.

[0135] The diameter of the cylindrical sponge is 36.4cm, the rectangular sponge is 30cm long and 10cm wide. During normal use, the telescopic hydraulic cylinder can stretch left and right by 40cm, and the width of the end sponge is controlled within 20 - 30cm. Calculate the maximum curing space for a double-track tunnel = 22.3m * 0.3m * 12m = 80.4m³.

[0136] The curing system mainly includes an electrothermal steam generation system and a warm water spraying system.

[0137] The electrothermal steam generation system consists of an electrothermal steam generator, steam pipelines, steam nozzles, 2m 3It consists of a steam water tank, etc. The steam generated by the steam generator is transported through the steam pipeline into the sealed space, mainly to raise the temperature of the lining curing, and at the same time the system ensures the internal humidity. It includes 2 electric steam generators of 60kW and 2 of 48kW, 6 main pipelines and 6 secondary pipelines for steam transmission, and 216 steam spray nozzles with a 120° wide-angle cone (at an interval of 30cm, a total of 36*6 = 216). The secondary pipelines are located at the 3rd, 4th, and 5th longitudinal support rods of the trolley. The 120° wide-angle cone steam spray nozzles can prevent the high-temperature steam from directly acting on the concrete and causing local damage. In the calculated sealed curing space, the steam can fill the curing space within 10 minutes.

[0138] It consists of a spray pump, a heater, and a 2.6m 3 water tank and a spray transmission pipeline. The 4 spray pipelines are respectively located at the 4th and 6th longitudinal support rods on both sides of the trolley. The secondary pipe is perforated every 50cm, with a total of 88 spray heads, and the spraying angle is perpendicular to the concrete surface. The heater keeps the temperature of the sprayed water at about 30°C to avoid too low local curing temperature. Spraying warm water at 30°C can quickly reduce the curing environment temperature, and when the temperature is higher than 35°C, the cooling is automatically started.

[0139] Combination of spraying and steam: The equipment is equipped with both an electric high-temperature steam and a warm water spraying system. According to the concrete curing requirements, the system evenly distributes an appropriate amount of steam and sprayed water on the concrete surface through the spraying device to ensure that the concrete is evenly heated and moistened, promote the hydration reaction, and accelerate the strength growth.

[0140] The technological process and operation key points of the spray-steam integrated curing trolley are as follows: (1) Before starting work, check various parts of the equipment such as the power system, steam generator, spraying system, transmission pipeline, etc., and adjust the equipment settings according to the actual environmental conditions. And ensure that the equipment safety protection devices are normal, including electrical overload protection, overpressure relief device, and waterproof measures.

[0141] (2) Turn on the power of the equipment, push the curing trolley forward closely behind the secondary lining trolley. After reaching the designated position, confirm the sufficient water volume in the water storage tank. According to the environmental data and curing requirements, set the spraying water volume, steam temperature, and curing time through the control panel, and start the top extension system to push the section seal and bottom seal to the surface of the secondary lining to form a tight sealed space.

[0142] (3) During the curing process, first start the spraying system to quickly wet the surface of the secondary lining. At the same time, start the electric steam generation system to transport the steam to the concrete surface to ensure the temperature and humidity of the curing environment. During the curing process, confirm the sealing of the curing environment to meet and maintain the temperature and humidity standards.

[0143] After the curing is completed, manually stop the spraying and steam systems according to the preset curing time. The professional personnel record the temperature and humidity data during the curing process, clean the equipment, and check for blockages in the spraying system or dirt in the steam pipeline to ensure the normal operation of the equipment during the next curing.

[0144] The present invention has the following characteristics: 1. Due to the design of the tunnel secondary lining trolley body 1 and the rear trolley components, through the tunnel secondary lining trolley body 1, a powered movement docking of the rear trolley components is achieved.

This solves the technical problem that existing ones can only be used for the construction of the tunnel secondary lining layer body, resulting in the construction and curing of the tunnel secondary lining layer body being in separate time periods. Therefore, the construction effect of the tunnel secondary lining layer body is improved.

[0145] 2. Due to the design of the support cover assembly 5 and the nozzle assembly 9, a covering and curing sealed interval curing of the tunnel secondary lining layer body is achieved.

[0146] 3. Due to the design of the steam generator 2, the fog-making device 3, and the spraying device 4, the factors required for curing the tunnel secondary lining in cold regions are met.

[0147] 4. Due to the design of the connecting rod 6, the ear seat 7, and the pin shaft 8, a socket connection between the tunnel secondary lining trolley body 1 and the rear trolley components is achieved.

[0148] 5. Due to the limitation of the numerical range of the structural shape, the numerical range is a technical feature in the technical solution of the present invention, rather than a technical feature obtained through formula calculation or a limited number of tests. Tests show that the technical features within this numerical range have achieved good technical effects.

[0149] 6. Due to the design of the technical features of the present invention, through the combined action of the technical features alone and among each other, tests show that each performance index of the present invention is at least 1.7 times that of the existing performance indexes, and it has good market value through evaluation.

[0150] There are also other technical features related to the connection between the tunnel secondary lining trolley body 1 and the rear trolley components for the linkage operation of the construction of the front-section tunnel secondary lining layer body and the curing of the rear-section tunnel secondary lining layer body in cold regions, which are all embodiments of the present invention. And the technical features of the above-mentioned embodiments can be combined arbitrarily. To meet the requirements of the Patent Law, the Patent Implementing Regulations, and the Examination Guidelines, the embodiments of all possible combinations of the various technical features in the above-mentioned embodiments will not be described one by one.
