For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.
[0037] In related technologies, such as Figure 1 As shown, the portion of the invert arch extending beyond the top surface of the backfill material 02 at both ends is called the low sidewall 01, and then the secondary lining is poured on the low sidewall 01. Currently, there are few maintenance measures for the low sidewall 01, almost no separate maintenance for the low sidewall 01, or only simple manual spraying maintenance, resulting in poor maintenance effect and hindering the stress distribution of the closed ring lining. Therefore, the technical solution of this application was developed, which is described below in conjunction with... Figures 1 to 3 To elaborate.
[0038] Example 1
[0039] like Figures 1 to 3As shown, the constant temperature spraying maintenance system for tunnel sidewalls of this utility model includes a pipe fixing bracket 1, a spray pipe 2, a water tank 4, a heating rod 6, and a temperature sensor.
[0040] like Figure 1 and Figure 2 As shown, the pipe fixing bracket 1 is located between the low side wall 01 and the filling body 02, as... Figure 3 As shown, the pipe fixing support 1 includes several circumferential supports 13 and several longitudinal supports 14. The circumferential supports 13 are arranged transversely along the tunnel, and the longitudinal supports 14 are arranged axially along the tunnel. Several longitudinal supports 14 are connected between adjacent circumferential supports 13. Figure 2 As shown, the circumferential support 13 includes an arc-shaped frame 131 and a right-angled frame 132. The right-angled frame 132 connects to the arc-shaped frame 131. The arc-shaped frame 131 is arranged along the inner sidewall of the low sidewall 01, and the right-angled frame 132 is matched to the position of the infill body 02; as shown. Figure 2 As shown, a plurality of first traveling pulleys 11 are provided along the outer side of the arc-shaped frame 131, and the first traveling pulleys 11 are attached to the low side wall 01. A plurality of second traveling pulleys 12 are provided along the outer side of the right-angle frame 132, and the second traveling pulleys 12 are attached to the filler 02, so that the pipe fixing bracket 1 can move along the length direction of the low side wall 01.
[0041] In this embodiment, as Figure 2 As shown, two first traveling pulleys 11 are spaced apart on the outer side of the arc-shaped frame 131, and a second traveling pulley 12 is provided on the outer side of the right-angle frame 132. The second traveling pulley 12 and one of the first traveling pulleys 11 are horizontally aligned and close to the top surface of the filler 02. This arrangement can lower the center of gravity of the circumferential support 13 and maintain the stability of the circumferential support 13. The other first traveling pulley 11 is close to the top surface of the low side wall 01, which helps to maintain the stability of the circumferential support 13.
[0042] like Figure 1 and Figure 2 As shown, the spray pipe 2 is connected to the pipe fixing bracket 1, and the spray pipe 2 is provided with a plurality of nozzles 22 at intervals on the side facing the low side wall 01; the water tank 4 is set on the movable arch bridge 03, and the water tank 4 is connected to the spray pipe 2; the heating rod 6 is set in the water tank 4, and the heating rod 6 heats the water in the water tank 4; the temperature sensor is set on the water tank 4, and the temperature sensor detects the temperature of the water in the water tank 4.
[0043] In one alternative implementation, such as Figure 1 and Figure 2As shown, the top edge of the right-angle frame 132 is flush with the top surface of the filling body 02. Since the movable arch bridge 03 occupies most of the working space of the filling body 02, a treadmill can be laid on the top edge of the right-angle frame 132 for construction workers to walk on, thus expanding the working space.
[0044] like Figure 3 As shown, the spray pipe 2 includes several circumferential pipes 23 and several longitudinal pipes 24. The circumferential pipes 23 are arranged along the circumferential support 13, and the longitudinal pipes 24 are arranged along the longitudinal support 14; as Figure 2 As shown, the spray pipe 2 is provided with several T-joints 21, and the T-joints 21 are connected to the spray head 22.
[0045] like Figure 1 As shown, a water tank mounting bracket 3 is provided on the movable arch bridge 03. The water tank mounting bracket 3 is equipped with a water pump 5, a controller and the water tank 4. The water pump 5 is connected to the water tank 4. The spray pipe 2 is connected to the water pump 5. The controller is electrically connected to the water pump 5, the heating rod 6 and the temperature sensor respectively. The controller can be an industrial computer or a PLC. The controller includes a time relay and can set the spray curing time.
[0046] This embodiment describes a constant-temperature spray curing system for tunnel sidewalls. By installing a pipe fixing bracket 1 that can move along the sidewall 01 to support and fix the spray pipe 2, and by placing a water tank 4 on a movable arch bridge 03, both the water tank 4 and the spray pipe 2 can move along the tunnel axis, achieving spray curing of the entire length of the sidewall 01 of the tunnel. By installing a heating rod 6 and a temperature sensor in the water tank 4, the sprayed water is ensured to be at a constant temperature, improving the spray curing effect. This spray curing system has a simple structure, is easy to use, and has good results.
[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
