Embodiment 1

[0024] Such as figure 1 As shown, in this embodiment, a spray maintenance device for a partition wall in a multi-arch tunnel includes several support devices 2 arranged on the partition wall, spray pipes 3 arranged on the support device 2 and several settings The spray nozzle 1 on the spray pipe 3 , the spray pipe 3 is connected with the spray fog machine 4 through the water outlet pipe, and the spray fog machine 4 is connected with the water inlet pipe 5 .

[0025] The support device 2 is constructed on the 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 partition wall, and the length of the spray pipe 3 can be equal to that of the middle partition wall. The length of the partition wall. When it is necessary to maintain the partition wall, the water inlet pipe 5 is used to deliver water to the spray fog machine 4, and the spray fog machine 4 transpor...

Embodiment 2

[0027] On the basis of the above embodiments, 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 position of 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 the water flow during the water supply process, thereby improving the stability of the spray pipe 3 and avoiding the spray nozzle 1. The spray range is affected and affects the maintenance effect of the partition wall.

[0028] In this embodiment, the supporting device 2 is provided with a slot 22 for installing the spray nozzle 1 . The spray nozzle 1 is installed by using the card slot 22, which is convenient to keep the spray nozzle 1 fixed, improves the stability of the spray nozzle 1, makes the spray nozzle 1 spray in a stable direction, and ensures that the sprayed water mist can cover the middle partition wall according to the design requirements .

Embodiment 3

[0033] On the basis of the above embodiments, in this embodiment, the support device 2 is detachably connected with a sleeve 23, and the sleeve 23 is prefabricated in the partition wall. During the construction of the partition wall, by prefabricating the sleeve 23 in the partition wall, after the construction of the partition wall is completed, it is convenient to quickly connect the support device 2 with the sleeve 23, which is conducive to improving construction efficiency, and the construction of the support device 2, there is no need to destroy the partition wall.

[0034] In this embodiment, the sleeve 23 is provided with a threaded hole, and the supporting device 2 is provided with a screw 24 connected with the threaded hole. The fast installation of the supporting device 2 is facilitated by the connection between the screw rod 24 and the threaded hole. And after the maintenance is completed, the support device 2 can be recycled, and the sleeve 23 remains in the partit...

Abstract

The invention discloses a spraying maintenance device and maintenance method for a partition wall in a multi-arch tunnel. The spraying maintenance device comprises a plurality of supporting devices arranged on the partition wall, spraying pipelines arranged on the supporting devices and a plurality of spraying nozzles arranged on the spraying pipelines; and the spraying pipelines communicate with a spraying mist making machine through water outlet pipes, and the spraying mist making machine communicates with a water inlet pipeline. The spraying maintenance device and maintenance method have the beneficial effects that according to the scheme, the spraying pipelines stretching into the tunnel can be utilized to spray water mist to the partition wall for maintenance, the protection effect can be enhanced, workers do not need to stretch into the tunnel, construction is more convenient and faster, and the safety of the workers can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of partition wall construction, in particular to a spray maintenance device and maintenance method for partition walls in multi-arch tunnels. Background technique [0002] The partition wall is constructed inside the tunnel and will occupy a large space in the tunnel, resulting in the remaining space in the tunnel being separated on both sides of the partition wall and relatively narrow. Maintenance is required after the partition wall is deflected during construction. However, due to the small remaining space inside the tunnel, manual watering is difficult, and the profile of the partition wall is irregular, so it is difficult to perform maintenance by manual watering. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a spray curing device and curing method for partition walls in multi-arch tunnels, which are used t...
