[0042] The following further details the present utility model in combination with the full text:

[0043] Embodiment 1:

[0044] Combined with the attached Figures 1 to 5This embodiment provides a lining concrete sprinkling and curing device for tunnel construction, including a water tank 1 for storing water and installing a sprinkler device to sprinkle water in the tunnel, and also including a water pump 101 fixedly connected to the top of the water tank 1 for pumping water. The output end of the water pump 101 is fixedly connected to a telescopic hose 102, and the end of the telescopic hose 102 away from the water pump 101 is fixedly connected to a fixed pipe 103. One end of the water pump 101 is fixedly connected to a water pumping pipe, and the end of the water pumping pipe away from the water pump 101 is located in the water tank 1.

[0045] As a preferred embodiment, a water inlet 5 for filling water into the water tank 1 is fixedly connected to the top of the water tank 1, an observation port 6 for observing the water amount in the water tank 1 is provided on one side of the water tank 1, a push handle 7 for pushing the water tank 1 to move is arranged on the top of one side of the water tank 1, and a universal wheel 8 for moving the water tank 1 is arranged at the bottom of the water tank 1.

[0046] It should be noted that there are four groups of universal wheels 8 evenly distributed on the water tank 1, the observation port 6 is made of transparent glass to facilitate observation of the water level in the water tank 1, and a rechargeable battery (not shown) is arranged on the top of the water tank 1 to power the water pump 101 and the electric telescopic rod 401.

[0047] In order to facilitate replacement and ensure sealing during watering, a water spray assembly is arranged. The water spray assembly includes an arc tube 104 fixed to one end of the fixed tube 103 and a connection sealing assembly for installing the connector 203.

[0048] As a preferred embodiment, the water spray assembly also includes: a water spray port 201, fixedly connected to the arc tube 104 for connecting to the connector 203; a threaded head 202, arranged at the end of the water spray port 201 away from the arc tube 104 for fixing the connector 203.

[0049] As a preferred embodiment, the connection sealing assembly includes: a retaining ring 204, fixed in the connecting head 203; a rubber gasket 205, arranged in the connecting head 203 and the rubber gasket 205 fits between the retaining ring 204 and the water outlet 201 to improve the sealing during the connection; a limiting ring 206, arranged on the connecting head 203; a nut 207, threadedly connected to the threaded head 202 to fix the water outlet 201 and the connecting head 203.

[0050] It should be noted that the inner diameter of the rubber gasket 205 is smaller than the inner diameter of the retaining ring 204, and the outer diameter of the rubber gasket 205 is consistent with the inner diameter of the connecting head 203. The inner wall of the connecting head 203 fits against the outer wall of the water outlet 201. The water outlet 201 and the connecting head 203 are fixed by tightening the nut 207 on the threaded head 202. The rubber gasket 205 is convenient for disassembly and replacement and has better sealing than directly threading the connecting head 203 to the water outlet 201.

[0051] As a preferred embodiment, five groups of water spray nozzles 201 are evenly distributed on the fixed pipe 103. The limiting ring 206 fits against the threaded head 202, and the nut 207 fits against the limiting ring 206.

[0052] It should be noted that the shape of the arc-shaped pipe 104 is arc-shaped, and the five groups of water spray nozzles 201 are evenly distributed, so that the inner wall of the tunnel can be sprayed simultaneously from multiple angles, ensuring the uniformity of water spraying.

[0053] Embodiment 2:

[0054] On the basis of Embodiment 1, an adjustment assembly is arranged to adjust the water spraying pressure according to the width and height of the tunnel. The adjustment assembly includes an adjustment plate 301 that slides inside the connection head 203 to adjust the water outlet pressure.

[0055] As a preferred embodiment, the adjustment assembly further includes: a threaded rod 302, which is rotatably connected through the connection head 203 and is used to drive the adjustment plate 301 to move to adjust the size of one end of the connection head 203; a turning handle 303, which is arranged at both ends of the threaded rod 302 to facilitate the rotation of the threaded rod 302; a limiting groove 304, which is arranged inside the connection head 203 for installing the adjustment plate 301 and the threaded rod 302.

[0056] As a preferred embodiment, two groups of adjustment plates 301 are provided and are symmetrically distributed. The threaded rod 302 is provided with two groups of opposite thread structures. The adjustment plate 301 slides inside the limiting groove 304, and the threaded rod 302 passes through the limiting groove 304.

[0057] It should be noted that by rotating the threaded rod 302 to drive the two groups of adjustment plates 301 to move in opposite directions, when the two groups of adjustment plates 301 move towards the middle at the same time, the outlet of the connection head 203 becomes smaller, which can increase the water outlet pressure, make the water spray farther, and is suitable for tunnels with a larger width. Moreover, each connection head 203 can be adjusted independently, making it more suitable for use in various tunnels.

[0058] Embodiment 3:

[0059] On the basis of Embodiments 1 and 2, a lifting mechanism is arranged to spray water on tunnels with a higher height. The lifting mechanism includes an electric telescopic rod 401 fixedly connected to the top of the water tank 1 for adjusting the height of the arc-shaped pipe 104.

[0060] As a preferred embodiment, the lifting mechanism further includes a mounting plate 402 fixedly connected to the top of the electric telescopic rod 401 for installing the fixed pipe 103 and the arc-shaped pipe 104. The fixed pipe 103 is fixedly connected through the mounting plate 402. The telescopic hose 102 is located below the mounting plate 402. Two groups of electric telescopic rods 401 are provided and are located on both sides of the telescopic hose 102.

[0061] It should be noted that when spraying water, the pressure in the telescopic hose 102, the fixed pipe 103, and the arc-shaped pipe 104 increases. The two groups of electric telescopic rods 401 simultaneously push the mounting plate 402 to move up and down, ensuring the stability during water spraying. After the mounting plate 402 rises, the distance between the connecting head 203 and the tunnel top is shortened. During the rising process of the mounting plate 402, the telescopic hose 102 will be stretched. The telescopic hose 102 belongs to the commonly known technology in this field.

[0062] The operation steps are as follows: Fill water into the water tank 1 through the water injection port 5. Then, the operator holds the push handle 7 and pushes the device into the tunnel through the universal wheels 8. Start the water pump 101 to pump the water in the water tank 1 through the telescopic hose 102 and the fixed pipe 103 into the arc-shaped pipe 104, and then spray water through the water spray port 201 and the connecting head 203 to sprinkle and cure the lining concrete in the tunnel. Start the electric telescopic rod 401 to push the mounting plate 402 to move upward. At this time, the telescopic hose 102 is stretched, and the arc-shaped pipe 104 moves upward to spray water on the tunnel with a higher height. And by rotating the rotating handle 303 to drive the threaded rod 302 to rotate, the two groups of adjusting plates 301 can be made to move towards the middle simultaneously, making the water outlet port of the connecting head 203 smaller, increasing the water spraying pressure so that the water can be sprayed farther. When the connecting head 203 needs to be replaced, only need to unscrew the nut 207 from the threaded head 202, and then the connecting head 203 can be removed.

[0063] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown throughout the text is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the creative concept of the present utility model, design structurally similar ways and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
