Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and particularly relates to a tunnel lining maintenance device. Background Art

[0002] At present, the secondary lining concrete of tunnels is maintained by manual watering and a multi-functional bench for knocking, detecting, and maintaining. The concrete strength is detected by a rebound instrument. However, during the implementation process, due to the limitations of manual watering maintenance, large on-site operation workload, and weak worker responsibility, the maintenance effect is not good. Also, due to the reasons that the maintenance construction of the second-generation multi-functional maintenance bench requires a long distance in the tunnel and the cooperation of a loader, etc., the maintenance quality cannot be effectively and continuously adhered to, and the strength of the lining concrete fails to meet the construction requirements. Summary of the Invention

The water blocking mechanism includes a driving mechanism and a water blocking plate. The driving mechanism is used to drive the water blocking plate to move, so as to open or close the second water seepage holes. The driving mechanism is electrically connected to the water level monitoring mechanism. When the water level monitoring mechanism detects that the water level in the first longitudinal pipe is higher than the first water seepage hole, the driving mechanism can drive the water blocking plate to open the second water seepage holes, and when the water level in the first longitudinal pipe is lower than the first water seepage hole, the driving mechanism can drive the water blocking plate to block the second water seepage holes.

[0009] Further, filter cloths are wrapped around the first water seepage holes of the first longitudinal pipe, and the second water seepage holes of the second longitudinal pipe and the transverse pipe.

[0010] Further, the driving mechanism includes a traction module, a traction rope and a spring. The traction module is located outside the second longitudinal pipe or the transverse pipe. The two ends of the traction rope are respectively connected to the water blocking plate and the traction module. The traction module pulls the water blocking plate downward through the traction rope to open the second water seepage holes. One end of the spring is connected to the water blocking plate, and the other end is connected to the bottom surface of the second water seepage pipe or the transverse pipe. The spring is used to drive the water blocking plate to abut against the second water seepage holes to close the second water seepage holes.

[0011] Further, each driving mechanism is connected to the water level monitoring mechanism through an electric wire, and the electric wire is fixed in the transverse pipe and / or the second longitudinal pipe through a wire clip.

[0012] Further, the water level monitoring mechanism includes a first detection electrode and a second detection electrode. The outer ends of the first detection electrode and the second detection electrode are both located below the first water seepage hole and are arranged at intervals.

[0013] Further, the water inlet is arranged on the first longitudinal pipe, and the water outlet is arranged on the lowermost second longitudinal pipe.

[0014] Further, the tunnel lining maintenance device further includes an arched framework, and the pipe rack is connected to the framework.

[0015] Further, a protective housing is arranged outside the traction module.

[0016] Further, temperature sensors are arranged on both the first longitudinal pipe and the second longitudinal pipe.

By measuring the temperature, controlling the temperature and humidity to improve the strength and surface density of the tunnel lining concrete, the pipe rack can be poured into the tunnel interior with concrete. The first longitudinal pipe and the second longitudinal pipe both extend along the extension direction of the tunnel. The surface of the pipe rack is equipped with a temperature sensor, and there are a certain number of small holes (the first water seepage hole and the second water seepage hole) evenly distributed near the top of the surface of the pipe rack. Different temperatures of water can be injected into the pipe rack through the water inlet, and the water flows to each position of the pipe rack. When the water level detection mechanism detects that the water level in the pipe rack rises to the first water seepage hole of the first longitudinal pipe at the highest position, each driving mechanism is driven to move the water blocking plate that blocks the second water seepage hole away, so as to open all the second water seepage holes, ensuring that water flows out from the first water seepage hole and the second water seepage hole at the same time. When the water injection into the pipe rack stops, the water level of the first longitudinal pipe at the highest position first drops. When it is lower than the water level detection mechanism, water no longer flows out from the first water seepage hole. At the same time, the driving mechanism drives the water blocking plate to block the second water seepage hole again, so as to achieve the effect of opening and closing the first water seepage hole and the second water seepage hole at the same time, and the temperature and humidity regulation of each part of the tunnel is carried out synchronously.

Specific embodiments

[0025] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0026] As Figures 1 - 4 shown, the tunnel lining maintenance device provided by the embodiment of the present invention includes a pipe rack. The tunnel lining maintenance device further includes an arched frame 8, which can be formed by tying steel bars, and the pipe rack can be connected to the frame by wire.

[0027] The pipe support includes a first longitudinal pipe 1 and a second longitudinal pipe 17 arranged in parallel. The first longitudinal pipe 1 is higher than the second longitudinal pipe 17. On the left side of the first longitudinal pipe 1, there are multiple second longitudinal pipes 17 whose vertical positions decrease in sequence. Among the multiple second longitudinal pipes 17 on the left side of the first longitudinal pipe 1, for two vertically adjacent second longitudinal pipes 17, the upper second longitudinal pipe 17 is closer to the first longitudinal pipe 1 in the left-right direction than the lower second longitudinal pipe 17. Among the multiple second longitudinal pipes 17 on the right side of the first longitudinal pipe 1, for two vertically adjacent second longitudinal pipes 17, the upper second longitudinal pipe 17 is closer to the first longitudinal pipe 1 in the left-right direction than the lower second longitudinal pipe 17. Between the first longitudinal pipe 1 and the two second longitudinal pipes 17 adjacent to it on the left and right, and between two vertically adjacent second longitudinal pipes 17, they are all connected by a cross pipe 2. The first longitudinal pipe 1, the second longitudinal pipe 17, and the cross pipe can all be connected by welding. There is a first water seepage hole 4 on the top wall of the first longitudinal pipe 1; there is a second water seepage hole 18 on the top walls of the second longitudinal pipe 17 and the cross pipe 2. The outer walls of the first water seepage hole 4 and the second water seepage hole 18 are wrapped with a filter mesh 5 to prevent the concrete from blocking the water seepage holes during pouring.

[0028] An inlet 6 and an outlet 7 are provided on the pipe support. The inlet 6 and the outlet 7 extend out of the tunnel, and water at a certain temperature can be input / output into / from the pipe support through the inlet 6 and the outlet 7 from the outside of the tunnel.

[0029] Temperature sensors 3 are provided on the outer wall of the pipe support. The number of temperature sensors 3 can be multiple. Temperature sensors 3 are arranged on the first longitudinal pipe 1 and each second longitudinal pipe 17 to detect the temperature at various positions in the tunnel and centrally control the temperature.

[0030] A water level monitoring mechanism is provided at the top wall of the first longitudinal pipe 1; a water blocking mechanism corresponding to the second water seepage holes 18 one by one is provided in the second longitudinal pipe 17 and the transverse pipe 2. The water blocking mechanism includes a driving mechanism and a water blocking plate 11. The driving mechanism is used to drive the water blocking plate 11 to move, so as to open or close the second water seepage holes 18. The driving mechanism is electrically connected to the water level monitoring mechanism. When the water level monitoring mechanism detects that the water level in the first longitudinal pipe 1 is higher than the first water seepage hole 4, the driving mechanism can drive the water blocking plate 11 to open the second water seepage holes 18, and when the water level in the first longitudinal pipe 1 is lower than the first water seepage hole 4, the driving mechanism can drive the water blocking plate 11 to block the second water seepage holes 18. By measuring the temperature, controlling the temperature and humidity to improve the strength and surface compactness of the tunnel lining concrete, the pipe rack can be cast in the tunnel with concrete. The first longitudinal pipe 1 and the second longitudinal pipe 17 both extend along the extension direction of the tunnel. The surface of the pipe rack is equipped with a temperature sensor 3, and there are a certain number of small holes (the first water seepage hole 4 and the second water seepage hole 18) evenly distributed near the top of the surface of the pipe rack. Water with different temperatures can be injected into the pipe rack through the water inlet 6. The water flows to various positions of the pipe rack. When the water level detection mechanism detects that the water level in the pipe rack rises to the first water seepage hole 4 of the first longitudinal pipe 1 at the highest position, each driving mechanism drives to move the water blocking plate 11 that blocks the second water seepage holes 18 away, so as to open all the second water seepage holes 18, ensuring that water flows out of the first water seepage hole 4 and the second water seepage holes 18 at the same time. When the water injection into the pipe rack stops, the water level in the first longitudinal pipe 1 at the highest position first drops. When it is lower than the water level detection mechanism, water no longer flows out of the first water seepage hole 4. At the same time, the driving mechanism drives the water blocking plate 11 again to block the second water seepage holes 18, so as to achieve the effect of opening and closing the first water seepage hole 4 and the second water seepage holes 18 at the same time, and the temperature and humidity regulation of each part of the tunnel is carried out synchronously.

[0031] The curing operation includes monitoring the temperature of each section, and at the same time injecting water with a suitable temperature into the pipe rack according to the temperature level, so that the temperature and humidity of this section can be guaranteed to be in the most suitable situation for concrete curing. After the curing is completed, grouting treatment is directly carried out on the pipe rack. This curing device can not only achieve the purpose of curing by adjusting the temperature and humidity, but also recycle the water in the curing process, and can also avoid the situation of water accumulation on the ground in the tunnel. At the same time, the pipe rack can also improve its strength and bearing capacity, and finally can significantly improve the tunnel lining quality, concrete strength and surface compactness. In addition, this device can not only make the casting and curing of the secondary lining seamless, but also cure multiple sections of lining at the same time without interference, so as to improve the curing construction efficiency.

[0032] The driving mechanism includes a traction module 16, a traction rope 13, and a spring 12. The traction module 16 is located outside the second longitudinal pipe 17 or the cross pipe 2. Both ends of the traction rope 13 are respectively connected to the water baffle 11 and the traction module 16. The traction module 16 pulls the water baffle 11 downward through the traction rope 13 to open the second water seepage holes 18. One end of the spring 12 is connected to the water baffle 11, and the other end is connected to the bottom surface of the second water seepage pipe or the cross pipe 2. The spring 12 is used to drive the water baffle 11 to abut against the second water seepage holes 18 to close the second water seepage holes 18. The traction module 16 of the driving mechanism corresponding to the second longitudinal pipe 17 is located outside the second longitudinal pipe 17, and the traction module 16 of the driving mechanism corresponding to the cross pipe 2 is located outside the cross pipe 2. When the water level detection mechanism detects that the water level in the pipe rack rises to the first water seepage holes 4 at the highest position of the first longitudinal pipe 1, each driving mechanism is driven to pull the water baffle 11 that blocks the second water seepage holes 18 downward, so as to open all the second water seepage holes 18 and ensure that water flows out of the first water seepage holes 4 and the second water seepage holes 18 simultaneously. When the water injection into the pipe rack stops, the water level of the first longitudinal pipe 1 at the highest position drops first. When it is lower than the water level detection mechanism, water no longer flows out of the first water seepage holes 4. At the same time, the traction module 16 no longer pulls the water baffle 11, and the spring 12 drives the water baffle 11 to move upward to block the second water seepage holes 18.

[0033] Each of the driving mechanisms is connected to the water level monitoring mechanism through a wire 15, and the wire 15 is fixed in the cross pipe 2 and / or the second longitudinal pipe 17 through a wire clip 9. The wire clip 9 is in a "concave" shape and can be connected to the pipe wall by screws. The wire 15 is led out to the outside of the pipe rack through the water inlet 6 or the water outlet 7.

[0034] The water level monitoring mechanism includes a first detection electrode 10 and a second detection electrode 19. The outer ends of the first detection electrode 10 and the second detection electrode 19 are both located below the first water seepage holes 4 and are arranged at intervals. After the water level in the first longitudinal pipe 1 rises above the outer ends of the first detection electrode 10 and the second detection electrode 19, the first detection electrode 10 and the second detection electrode 19 are conducted, so as to detect that the water level reaches the first water seepage holes 4.

[0035] The water inlet 6 is arranged on the first longitudinal pipe 1, and the water outlet 7 is arranged on the lowermost second longitudinal pipe 17. Water flows to the second longitudinal pipe 17 gradually from top to bottom.

[0036] A protective housing 14 is arranged outside the traction module 16 to prevent damage to the traction module 16 during pouring. The traction module 16 can be a small winch.

[0037] The tunnel lining maintenance device includes a water circulation mechanism. The water circulation mechanism is connected to the water inlet 6 and the water outlet 7 to realize the recycling of water and save resources.

[0038] After the tunnel maintenance is completed, grouting treatment can be carried out on the pipe rack to make the pipe rack become a part of the tunnel.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
