[0022] The present invention is further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0023] Embodiment 1:

[0024] like Figure 1 As shown, in this embodiment, a spray maintenance device for the middle partition wall of a multi-arch tunnel includes a plurality of support devices 2 arranged on the middle partition wall, a spray pipe 3 arranged on the support device 2, and a plurality of spray nozzles 1 arranged on the spray pipe 3. The spray pipe 3 is connected to a spray mist maker 4 through a water outlet pipe, and the spray mist maker 4 is connected to a water inlet pipe 5.

[0025] The support device 2 is constructed on the middle partition wall, and the spray pipe 3 is installed on the support device 2. The length of the spray pipe 3 extending into the tunnel is designed according to the length of the middle partition wall, and the length of the spray pipe 3 can be equal to the length of the middle partition wall. When the middle partition wall needs to be maintained, water is transported to the spray mist maker 4 through the water inlet pipe 5. The spray mist maker 4 transports water to the inside of the tunnel, and then sprays it through the spray nozzle 1 to form water mist. The water mist is used to maintain the middle partition wall, and the water consumption can be reduced. The water mist can evenly cover the outer surface of the middle partition wall to ensure the effect of the maintenance of the middle partition wall. In addition, the spray pipe 3 can penetrate into the interior of the tunnel, and the staff does not need to enter the deep part of the tunnel, which makes the construction more convenient, is conducive to ensuring the safety of the staff, and facilitates the maintenance of the whole range of the middle partition wall.

[0026] Embodiment 2:

[0027] On the basis of the above embodiment, in this embodiment, the support device 2 is provided with a groove 21 for installing the spray pipe 3. The groove can be used to limit the spray pipe 3, so as to prevent the spray pipe 3 from being separated from the support device 2 due to the impact of water flow during the water supply process, thereby improving the stability of the spray pipe 3 and preventing the spray range of the spray nozzle 1 from being affected and affecting the maintenance effect of the middle partition wall.

[0028] In this embodiment, the support device 2 is provided with a slot 22 for mounting the spray nozzle 1. The slot 22 is used to mount the spray nozzle 1, so that the spray nozzle 1 can be kept fixed, the stability of the spray nozzle 1 can be improved, and the spray nozzle 1 can spray in a stable direction, so as to ensure that the sprayed water mist can cover the middle partition wall according to the design requirements.

[0029] In this embodiment, the clamping slot 22 is rotatably arranged on the supporting device 2. When the clamping slot 22 is rotated upward, it is convenient to install the spray pipe 3 into the groove 21, or to separate the clamping slot 22 from the spray nozzle 1, and to conveniently remove the spray pipe 3. When the clamping slot 22 is rotated downward, it is convenient to connect the clamping slot 22 with the spray nozzle 1, and the clamping slot 22 can also be used to play a certain limiting role on the spray pipe 3 to prevent the spray pipe 3 from falling from the supporting device 2.

[0030] In this embodiment, the support device 2 is provided in two rows and symmetrically arranged on both sides of the middle partition wall along the length direction of the middle partition wall, and the spray pipe 3 is U-shaped. This facilitates the simultaneous arrangement of the same spray pipe 3 on both sides of the middle partition wall, so that spraying can be achieved using one set of water supply devices, which is conducive to reducing construction costs.

[0031] In this embodiment, the clamping groove 22 is a U-shaped clip made of elastic material, and the elastic deformation of the clamping groove 22 is used to conveniently clamp the spray nozzle 1. An arc-shaped groove can be provided on the clamping surface where the clamping groove 22 contacts the spray nozzle 1, so as to conveniently restrict the spray nozzle 1 in the arc-shaped groove, prevent the spray nozzle 1 from being separated, and improve the position accuracy and stability of the spray nozzle 1.

[0032] Embodiment 3:

[0033] On the basis of the above embodiment, in this embodiment, the support device 2 is detachably connected with a sleeve 23, and the sleeve 23 is prefabricated in the middle partition wall. When constructing the middle partition wall, by prefabricating the sleeve 23 in the middle partition wall, after the construction of the middle partition wall is completed, the support device 2 can be quickly connected to the sleeve 23, which is conducive to improving construction efficiency, and when constructing the support device 2, there is no need to destroy the middle partition wall.

[0034] In this embodiment, a threaded hole is provided in the sleeve 23, and a screw 24 connected to the threaded hole is provided on the support device 2. The connection between the screw 24 and the threaded hole facilitates the rapid installation of the support device 2. Moreover, the support device 2 can be recycled after maintenance, and the sleeve 23 is left in the middle partition wall as a part of the middle partition wall, so that no construction waste is generated, and production costs are saved.

[0035] Embodiment 4:

[0036] On the basis of the above embodiment, in this embodiment, the spray pipe 3 is provided with several sections, and two adjacent sections of the spray pipe 3 are sealed and connected. This facilitates the self-assembly of the spray pipe 3 of a suitable length according to the length of the middle partition wall, while ensuring the maintenance effect and avoiding the waste of materials and resources.

[0037] In this embodiment, a plurality of pressure sensors are arranged at intervals in the spray pipe 3. The pressure sensor can detect the water pressure at various locations in the spray pipe 3 in real time, and can determine whether there is a water leak in the spray pipe 3 according to the water pressure, and can quickly check according to the sensor that detects abnormal water pressure. Marks can be set on the outside of the spray pipe 3 at the position of the sensor.

[0038] Embodiment 5:

[0039] On the basis of the above-mentioned embodiments, in this embodiment, a reel 6 is provided at the connection point between the spray pipe 3 and the water outlet pipe, and reel baffles 7 are provided at both ends of the reel 6. The spray pipe 3 can be wound around the outer surface of the reel 6 when not in use. The reel baffle 7 can limit the winding range of the spray pipe 3 and prevent the wound spray pipe 3 from slipping off from both ends of the reel 6.

[0040] In this embodiment, a T-shaped three-way hole is provided in the reel 6, and the spray pipe 3 and the water outlet pipe are arranged in the three-way hole and extend out from the outlet end of the three-way hole, so as to conveniently limit the connection between the spray pipe 3 and the water outlet pipe within the reel 6. When storing the spray pipe 3, the spray pipe 3 and the water outlet pipe can be wound around the reel 6 by rotating the reel 6, which has the advantages of convenient use and convenient storage.

[0041] In this embodiment, other contents not described are the same as those in the above embodiment, and thus will not be described in detail.

[0042] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
