Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction monitoring, and in particular to a tunnel combined repair to separate repair construction monitoring device and a use method in a small clearance environment. Background Art

[0002] Tunnel engineering is an important part of modern transportation construction. The choice of construction method is directly related to the economic efficiency, safety, environmental friendliness and social benefits of the project. In the tunnel planning and design stage, common construction schemes include separate construction (i.e. separate tunnels) and combined construction (i.e. continuous arch tunnels or single-hole bidirectional tunnels);

[0003] Separate tunnels: Due to the dual-hole design, each tunnel independently carries one-way traffic, and its initial construction cost is relatively high, requiring separate tunnel excavation, support, lining and other projects. However, in the long run, separate tunnels are conducive to traffic organization and reduce additional investment due to expansion or maintenance in the later stage;

[0004] Jointly built tunnels: By sharing the tunnel space, some excavation and support works are reduced, and the initial construction cost is relatively low. However, for large-span or difficult jointly built tunnels (such as double-arch tunnels), the construction technology and materials are more demanding, which may increase the unit cost.

[0005] At present, the construction process is being used to prevent the occurrence of construction environmental pollution incidents and ensure that the impact of construction activities on the surrounding environment and residents' lives is minimized. Once the concentration of dust and harmful gases (such as carbon monoxide, nitrogen oxides, sulfur dioxide, etc.) generated in the air in the tunnel construction area rises to a certain level and construction work is carried out in this environment for a long time, the health of construction workers and the air quality of the construction environment cannot be guaranteed. The prior art generally sets up air quality monitoring points at the entrances and exits of tunnels and in construction areas, and regularly monitors the concentration of pollutants in the air using air detectors. According to subsequent monitoring results, measures such as sprinkling water to reduce dust and ventilation are taken. The health of construction workers cannot be guaranteed through regular inspections and means such as sprinkling water to reduce dust and ventilation. Therefore, the present application provides a tunnel joint repair to separate repair construction monitoring device and a method of use in a small clearance environment to meet the needs.

[0024] By setting a hollow resistance plate installed on the vertical pressure rod, it can contact and squeeze the corresponding two arc-surface resistance blocks during the downward movement, so that the two arc-surface resistance blocks can translate in opposite directions to each other in the annular groove. During the translation process, the two arc-surface resistance blocks will slide on the corresponding sliding rods to limit the movement, thereby squeezing the corresponding installed springs.

[0043] like Figure 1 and Figure 8As shown, an embodiment of the present invention provides a tunnel joint repair to separate repair construction monitoring device in a small clearance environment, including a purification chassis 1, an air dispersion port is provided on one end of the purification chassis 1 near the top, an air detector 11 is fixedly connected to the top of the purification chassis 1, dust outlet grooves 12 are provided on both sides of the bottom of the purification chassis 1, and material plugs 13 can be intermittently and tightly clamped in the inner walls of the two dust outlet grooves 12, a purification part 2 is also provided in the purification chassis 1, and the purification part 2 includes a suction pump 21 for sucking air, a suction pipe 22 is fixedly connected to one end of the suction pump 21, and a movably sleeved on the other end of the suction pipe 22 A hollow ball valve 23, the other end of which is movably sleeved with a wind bucket 24, an intermittent pressing structure is provided between the wind bucket 24 and the suction tube 22, for allowing the wind bucket 24 to swing, a partition 28 is fixedly connected to the inner wall of the purification chassis 1, a plurality of air holes 29 are provided through the bottom end of the partition 28, three filter screens 230 are staggered and fixedly connected to the inner wall of the partition 28, activated carbon is placed in the inner cavity of each filter screen 230, for purifying harmful substances in the building air, piston water sprinkling structures are provided on both sides of the top of the partition 28, for reducing dust contained in the air;

[0044] The intermittent pressing structure includes a small wind wheel 25 movably sleeved on a section of the rod body of the suction tube 22, and cams 26 are fixedly connected to both ends of the small wind wheel 25. One end of the two cams 26 can be intermittently fitted and slidably connected to the outer wall of both sides of one end of the wind bucket 24, thereby realizing the angle swing of the wind bucket 24.

[0045] The outer wall of one end of the suction pump 21 is fixedly connected to the outer wall of one end of the purification chassis 1 , and a delivery pipe 27 is fixedly connected to the top of the suction pump 21 , and the other end of the delivery pipe 27 is fixedly connected to one end of the purification chassis 1 .

[0046] By adopting the above scheme, the suction pump 21 will suck the gas through the suction pipe 22 and the wind bucket 24, and the gas passing through the suction pipe 22 will drive the small wind wheel 25 to rotate, and the rotating small wind wheel 25 will drive the cams 26 installed oppositely at both ends to rotate in real time, so that the two cams 26 will alternately press the side wall of the wind bucket 24 during the rotation process, causing the linked hollow ball valve 23 to tilt and swing synchronously, thereby increasing the intermittent suction of gas at different angles when the wind bucket 24 passively inhales gas, and improving the flexibility and applicability of the suction process of the wind bucket 24. , and then the gas entering the purification chassis 1 through the delivery pipe 27 will naturally rise, and some dust impurities contained in it will be filtered through a plurality of air holes 29 on the bottom end of the partition 28, so that the gas can rise without impurities, and the continuously rising gas will contact the filter screen plate 230. The filter screen plate 230 installed at multiple inclined angles can make the gas repeatedly contact the filter screen plate 230 in a baffled manner, and then it will be subjected to multi-stage purification through multiple filter screen plates 230, so that some harmful gases contained in the air can be purified, and finally discharged from the air diffuser on the purification chassis 1.

[0047] like Figure 5 and Figure 7 As shown, the two piston water-spraying structures each include a water tank 238 and a rubber piston plate 237 that is fitted and slidably connected in the water tank 238, a plurality of vertical pressure rods 239 are fixedly connected to the bottom end of the rubber piston plate 237, and a hollow abutment plate 240 is fixedly connected to the rod body of each vertical pressure rod 239, and a plurality of annular grooves 241 are provided in the inner wall of the bottom end of the water tank 238, and a water outlet hole 242 is provided at the upper and lower ends of each annular groove 241, and water can be sprayed out from each corresponding water outlet hole 242 by moving the plurality of hollow abutment plates 240 downward, thereby realizing dust reduction operation;

[0048] A large wind wheel 231 is movably sleeved on a section of the plate body of the partition 28, and a rotating plate 232 is fixedly connected to both ends of the large wind wheel 231. A T-shaped handle 233 is fixedly connected to the side wall of one end of each rotating plate 232, and a hinge plate 234 is slidably connected to the T-shaped handle 233. An arc-shaped long groove 235 is opened through the plate body of the hinge plate 234, and the T-shaped handle 233 and the inner wall of the arc-shaped long groove 235 are fitted and slidably connected. A U-shaped push-pull plate 236 is hinged on the top of the hinge plate 234, and the U-shaped push-pull plate 236 and the bottom end of the water tank 238 are slidably connected. The top of the U-shaped push-pull plate 236 and the bottom end of the rubber piston plate 237 are fixedly connected, and a water pipe is fixedly connected to one end of the water tank 238, and a water plug can be intermittently and tightly clamped in the inner wall of one end of the water pipe.

[0049] The above scheme is adopted: the continuous rise of gas after passing through multiple filter plates 230 will drive the large wind wheel 231 to rotate, and the rotating large wind wheel 231 will synchronously drive the rotating plates 232 on both ends to rotate, and the rotation of the rotating plates 232 will drive the T-shaped handle 233 to slide in the arc-shaped long groove 235 in the hinge plate 234. Therefore, when the T-shaped handle 233 is passively rotated 90 degrees, it will slide down to the bottom of the arc-shaped long groove 235. The subsequent continuous rotation of the T-shaped handle 233 will drive the U-shaped push-pull plate 236 to move downward through the hinge plate 234. The downward movement of the U-shaped push-pull plate 236 can synchronously drive the rubber piston plate 237 to slide down in the water tank 238, and then the rubber piston plate 237 can drive the installed multiple vertical pressure rods 239 to move downward synchronously.

[0050] like Figure 7 and Figure 8 As shown, the two piston water sprinkler structures also include two arc-surface blocks 243 that are fitted and slidably connected in each annular groove 241, and the outer wall of each hollow resistance plate 240 can be fitted and slidably connected with the inner wall of each water outlet hole 242, and the outer wall of each hollow resistance plate 240 can also be fitted and slidably connected with the outer wall of one end of each group of arc-surface blocks 243, and a rod groove 244 is opened in one end of each group of arc-surface blocks 243, and a sliding rod 245 is slidably connected in each group of rod grooves 244, and one end of each group of sliding rods 245 is fixedly connected to the inner walls at both ends of each group of annular grooves 241, and a spring 246 is fixedly connected between the outer wall of one end of each group of arc-surface blocks 243 and the inner walls at both ends of each group of annular grooves 241.

[0051] The above scheme is adopted: the hollow resistance plate 240 installed on the vertical pressure rod 239 can contact and squeeze the corresponding two arc-surface resistance blocks 243 during the downward movement, so that the two arc-surface resistance blocks 243 can translate in opposite directions in the annular groove 241. During the translation of the two arc-surface resistance blocks 243, they will slide on the corresponding slide rods 245 to limit the position, thereby squeezing the corresponding installed springs 246. Through the springs 246, the two arc-surface resistance blocks 243 can be reset after the two arc-surface resistance blocks 243 are not limited by external force. As a result, the water placed in the water tank 238 can be dispersedly sprayed through the hollow resistance plate 240 and the opened water outlet 242 under the condition of piston squeezing, thereby reducing the dust in the purification chassis 1, making it convenient for subsequent workers to take out the material plug 13 in the dust outlet trough 12, and carry out a unified cleaning process for the dust in the purification chassis 1, thereby avoiding the possibility of secondary dust entrainment during cleaning.

[0052] The working principle provided by the present invention is that the air quality index of the tunnel construction site can be monitored in real time through the air detector 11 installed on the top of the purification box 1. If the concentration of harmful gases exceeds the standard, the result will be automatically converted into an electrical signal output through the air detector 11, thereby realizing the function of automatically starting the suction pump 21 and performing air quality detection. The suction pump 21 after starting will suck the gas through the suction pipe 22 and the wind bucket 24. The gas passing through the suction pipe 22 will drive the small wind wheel 25 to rotate. The rotating small wind wheel 25 will drive the cams 26 installed oppositely on both ends to rotate in real time. Therefore, the two cams 26 will alternately press the side walls of the wind bucket 24 during the rotation, causing the linked hollow ball valve 23 to rotate synchronously. The tilted swing can improve the intermittent suction of gas at different angles when the wind bucket 24 passively inhales gas, thereby improving the flexibility and applicability of the suction process of the wind bucket 24. Then, the gas entering the purification box 1 through the pipe 27 will naturally rise, thereby filtering some dust impurities contained in it through a plurality of air holes 29 on the bottom end of the partition 28, so that the gas can rise without impurities. The continuously rising gas will contact the filter screen plate 230. The filter screen plates 230 installed at multiple tilted angles can make the gas repeatedly contact the filter screen plate 230 in a baffled manner, and then perform multi-stage purification on it through multiple filter screen plates 230, so that some harmful gases contained in the air can be purified and finally discharged from the air diffuser on the purification box 1;

[0053] When the gas continues to rise after passing through the multiple filter screens 230, it will drive the large wind wheel 231 to rotate. The rotating large wind wheel 231 will synchronously drive the rotating plates 232 on both ends to rotate, and the rotation of the rotating plates 232 will drive the T-shaped handle 233 to slide in the arc-shaped long groove 235 in the hinge plate 234. Therefore, when the T-shaped handle 233 is passively rotated 90 degrees, it will slide down to the bottom of the arc-shaped long groove 235. The subsequent continuous rotation of the T-shaped handle 233 will drive the U-shaped push-pull plate 236 to move downward through the hinge plate 234. The downward movement of the U-shaped push-pull plate 236 can synchronously drive the rubber piston plate 237 to slide down in the water tank 238, and then the rubber piston plate 237 can drive the installed multiple vertical pressure rods 239 to move downward synchronously. The hollow resistance plate 240 installed on the vertical pressure rod 239 can contact and squeeze the corresponding two arc-shaped resistance blocks 243 during the downward movement, so that the two arc-shaped resistance blocks 243 are pressed downward. The stopper 243 translates in opposite directions within the annular groove 241. During the translation process, the two arc-surface stopper 243 will slide on the corresponding slide bar 245 to limit the position, thereby squeezing the corresponding installed spring 246. The spring 246 can drive the two arc-surface stopper 243 to reset after the two arc-surface stopper 243 is not limited by external force. As a result, the water placed in the water tank 238 will be dispersedly sprayed through the hollow stopper plate 240 and the opened water outlet 242 under the condition of piston squeezing, thereby reducing the dust in the purification chassis 1, making it convenient for subsequent workers to take out the material plug 13 in the dust outlet trough 12, and uniformly clean the dust in the purification chassis 1, thereby avoiding the possibility of secondary dusting during cleaning. Therefore, while monitoring the air quality of the construction environment in real time, it can also be immediately processed accordingly, greatly improving the construction environment of the staff.

[0054] It should be added that once the suction pump 21 is started, it will continue to work for 20 minutes, so even if the concentration of air exceeds the standard temporarily locally, the air in a large area will be purified by this device.

[0055] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the following preferred embodiments of the present invention, but those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.

10. A method for using a monitoring device for tunnel joint repair to separate repair construction in a small clearance environment, using the monitoring device for tunnel joint repair to separate repair construction in a small clearance environment as claimed in any one of claims 1 to 9, characterized in that: The specific operation process is as follows: S1. The suction pump will suck the gas through the suction pipe and the wind bucket, and then the gas entering the purification box through the delivery pipe will rise naturally, and then some dust impurities contained in it will be filtered through several air holes on the bottom of the partition, so that the gas can rise without impurities. The continuously rising gas will contact the filter screen plate. The filter screen plates installed at multiple inclined angles can make the gas repeatedly contact the filter screen plate in a baffled manner, and then it will be purified in multiple stages through multiple filter screen plates, so that some harmful gases contained in the air can be purified; S2. The hollow resistance plate installed on the vertical pressure rod can contact and squeeze the corresponding two arc-surface resistance blocks during the downward movement, so that the two arc-surface resistance blocks can translate in opposite directions in the annular groove. During the translation of the two arc-surface resistance blocks, they will slide on the corresponding sliding rods to limit the movement, thereby squeezing the corresponding installed springs. As a result, the water placed in the water tank will be dispersedly sprayed through the hollow resistance plate and the opened water outlet holes under the condition of piston squeezing, thereby reducing the dust in the purification box, making it convenient for subsequent workers to take out the material plug in the dust outlet trough and carry out a unified cleaning process for the dust in the purification box, avoiding the possibility of secondary dusting during cleaning.
