Problems solved by technology

[0003] The purpose of the present invention is to overcome the tunnel lining and carry out water spray maintenance through the tunnel maintenance trolley. The concrete surface is uniformly sprayed with water through the nozzle. If the concrete surface is still dry, a large amount of water spray is used to moisten the concrete surface, and a large amount of water flows to the ground. Due to the small amount of water attached to the concrete surface during the water spray curing process, the concrete surface still cannot guarantee a long-term wetness. The surface of the concrete is sprayed. Water maintenance is difficult to achieve the expected effect. Through reasonable design, a method for using the trolley for tunnel lining maintenance and film coating is provided. The lining film maintenance trolley of the present invention drives the film covering mechanism through the film covering trolley, and through the film covering mechanism The film roll is installed on the film roll insertion shaft, and the film is adhered to the surface of the inner wall of the lining concrete by the rolling of the film roll for moisturizing and maintenance. After the film is covered, the moisture emitted in the concrete after the tunnel lining is demoulded can be retained for a long time. On the surface of the concrete, the time for moisturizing and curing the lining concrete is longer, which improves the curing effect and does not cause rapid absorption or volatilization and drying of the concrete surface; reduces the waste of water resources, optimizes the production environment, and can ensure that the lining concrete during maintenance Moisturizing the inner wall, improving construction progress and quality

Embodiment 1

[0018] At least two gantry frames 19 are arranged at the front end and the rear end of the lining film-covered maintenance trolley 1, and the lower ends of the columns on both sides of the gantry frame 19 are respectively provided with trolley lifting support frames 18; Bottom beams are arranged between them, and walking wheels 2 are respectively set between the two ends of the bottom beams on both sides and the ground; telescopic platforms 8 are arranged symmetrically in the lower and middle parts of both sides of the lining film-covered maintenance trolley 1, and the top of the lining film-covered maintenance trolley 1 The top platform 9 is symmetrically arranged on both sides, and the top platform 9 and the telescopic platform 8 are respectively set as manual operation platforms; the outer side of the lining film-covered maintenance trolley 1 corresponds to the lining concrete inner wall 10. A pair of arc-shaped trolley tracks 3, a pair of trolley A trolley channel is set be...

Embodiment 2

[0023]After the film coating at the bottom of the film-coated roll is completed, the film-coating pressure roller 14 is stretched out through the automatic lifting frame 12, and the film-coating pressure roller 14 is laminated by pressing the back of the film and lining the inner wall of the concrete 10. At the same time, open the The valve of the airflow cleaning nozzle 16 and the starting trolley driving device 5 pull the film-coated trolley 4 to move upward along the trolley track 3 through the pull rope 7; during the walking process of the film-coated trolley 4, the airflow cleaning nozzle 16 will pass the airflow to the surface of the lining concrete inner wall 10. The dust is cleaned continuously; at the same time, the film of the film roll on the film roll insertion shaft 15 is pulled out, the film pressure roller 14 rotates, and the top presses the film and the inner wall of the lining concrete 10 for continuous film coating; When the trolley 4 runs to the other end of ...

Embodiment 3

[0025] After the film-covering maintenance in the first construction section, the film-covering trolley 4 returns to the starting end, lowers the lining film-covering maintenance trolley 1 through the trolley lifting support frame 18, and runs forward through the traveling wheels 2 until it is less than the width of the film-covering roll 1. Stop after reserving the width of the lap joint, repeat the process of film maintenance in the first construction section above, and carry out the film maintenance construction of the rear lining concrete inner wall 10 continuously by the film coating trolley 4.

Abstract

The invention provides a use method of a tunnel lining maintenance film-coating trolley. The use method comprises the steps that film-coating maintenance is conducted on the inner wall of lining concrete, and a film-coating roll is manually mounted by an operator; a valve of an airflow cleaning nozzle is opened, a trolley driving device is started, a film-coating trolley is pulled through a pulling rope to walk upwards along a trolley track, and dust on the surface of the inner wall of the lining concrete is continuously cleaned through airflow by the airflow cleaning nozzle; meanwhile, a film-coating roll on a film roll inserting shaft is pulled out, and a film-coating pressing roller rotates to jack and press the film-coating roll to be continuously attached to the inner wall of the lining concrete for film coating; and film-coating maintenance construction of the inner wall of the lining concrete at the rear section is continuously conducted through the film-coating trolley. According to the lining film-coating maintenance trolley, the film-coating trolley drives a film-coating mechanism to conduct moisturizing maintenance on the surface, attached to the inner wall of the lining concrete, of the film-coating roll, moisture emitted in the concrete is reserved on the surface of the concrete for a long time, moisturizing of the inner wall of the lining concrete during maintenance can be ensured, the construction progress is accelerated, and the construction quality is improved.

Description

technical field [0001] The invention relates to the use of a tunnel lining maintenance trolley, in particular to a method for using a tunnel lining maintenance trolley. Background technique [0002] At present, in the tunnel construction process, the concrete surface of the tunnel lining needs to be maintained after the tunnel lining construction is demoulded. Usually, the concrete surface is maintained by spraying water; the existing tunnel lining is maintained by spraying water through a tunnel maintenance trolley. During the maintenance process of the tunnel maintenance trolley, the concrete surface is evenly sprayed with water through the nozzle, and the concrete surface is quickly absorbed or volatilized after spraying water. Sometimes, the concrete surface is still dry after spraying water. In order to moisten the concrete surface, a large amount of spray is used. A large amount of water flows to the ground and pollutes the production environment. Due to the small amou...
