Description

Technical Field

[0001] This utility model belongs to the field of continuous beam maintenance technology, specifically relating to a maintenance structure for railway continuous beams. Background Technology

[0002] Spray curing of cast-in-place continuous beams is a key step to ensure the normal hardening and strength development of concrete. In existing technologies, spray curing devices are often used to spray curing continuous beams.

[0003] For example, CN206721689U discloses a maintenance structure for a continuous railway beam. This utility model uses two combined maintenance pipelines to spray and maintain the flange plates, web plates, and bottom plates of the box girder. However, since the continuous beam uses a large amount of water during spray maintenance, it may consume a lot of water every day. If this water is directly discharged into the environment, it will waste water resources.

[0004] On the other hand, the wastewater generated by spray curing contains pollutants such as cement slurry, silt, and dust. If discharged directly without treatment, it may pollute the water, soil, and ecological environment near the curing device. For example, during spray curing, some incompletely hardened cement slurry on the surface of the continuous beam will be washed down and mixed into the wastewater. Cement slurry contains a large amount of calcium hydroxide, which makes the wastewater alkaline (pH value is usually between 12 and 13). During long-term spray curing, the wastewater dripping directly onto the continuous beam will cause soil alkalization at the curing location, affecting the soil's acid-base balance, inhibiting plant growth, and causing soil compaction, affecting the subsequent use of the soil at the curing location.

[0005] Therefore, a continuous beam curing structure that can filter and recycle wastewater from spray curing is needed to solve the above problems. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides a railway continuous beam maintenance structure, which solves the problems of water waste and soil damage caused by the large amount of wastewater generated during the spraying maintenance of continuous beams.

[0007] The purpose of this utility model can be achieved through the following technical solution: a railway continuous beam maintenance structure, including a continuous beam body and maintenance components, wherein the maintenance components are used to spray the surface of the continuous beam for maintenance, the maintenance components include a water storage tank, the rear end of the water storage tank is connected to a first water pump, a support frame is erected on the upper surface of the continuous beam body, and maintenance pipes are provided on the support frame.

[0008] It also includes a recycling component, which includes a water collection box, a recycling pipe, a second water pump, and a filter device. The water collection box is located below the continuous beam. The water collection box is connected to one end of the filter device through the recycling pipe. The other end of the filter device is connected to a water storage tank through the second water pump. The second water pump pumps the water in the water collection box through the recycling pipe and the filter device to the water storage tank.

[0009] Preferably, the maintenance pipeline includes a main pipeline, maintenance branch pipes, and atomizing nozzles. The main pipeline is connected to a first water pump and is arranged in a ring above the continuous beam. The main pipeline is connected to a water storage tank through the first water pump.

[0011] The first water pump, the second water pump, the third water pump, and the flow meter are electrically connected to the controller and are controlled by the controller.

[0012] The flow meter is used to monitor the water flow rate through the second water pump and transmit it to the controller, which controls the operation of the third water pump based on the water flow rate.

[0013] Preferably, the filtration device includes a filter box and a filter screen disposed inside the filter box, and the filter screen is provided with a sealing ring on its edge.

Furthermore, the recovered water is filtered through a recycling system and reused for spraying, ensuring its pH level remains unaffected. This approach saves water and reduces the impact of direct water dripping on the soil.

[0019] Furthermore, by monitoring the workload of the second water pump using a flow meter, the amount of curing wastewater can be monitored.

Detailed Implementation

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] Please see Figures 1-4 This embodiment provides a railway continuous beam maintenance structure, including a continuous beam body 1 and a maintenance component 2. The maintenance component is used to spray the surface of the continuous beam for maintenance. The maintenance component 2 includes a water storage tank 201. A first water pump 202 is connected to the rear end of the water storage tank 201. A support frame 204 is erected on the upper surface of the continuous beam body 1. Maintenance pipes are installed on the support frame 204.

[0028] It also includes a recycling component, which comprises a water collection box 207, a recycling pipe 208, a second water pump 209, and a filter assembly 3. The water collection box 207 is located below the continuous beam. When the maintenance component 2 sprays water onto the continuous beam, excess water drips down. The water collection box 207 effectively collects the water dripping from the continuous beam. One end of the recycling pipe 208 is connected to the filter assembly 3, and the other end of the filter assembly 3 is connected to the water storage tank 201 via the second water pump 209. The second water pump 209 pumps the water in the water collection box 207 through the recycling pipe 208 and the filter assembly 3 into the water storage tank 201. The filter assembly 3 includes a filter box 301 and a filter screen 303 installed inside the filter box 301. The filter screen 303 filters particulate matter in the water, reducing the clogging of the water pump caused by particulate matter. The edge of the filter screen 303 is provided with a sealing ring to prevent external substances from drifting into the filter box 301 and causing subsequent clogging.

[0029] Collecting water dripping from the continuous beam via the water collection box 207 conserves water resources. Furthermore, during the period before the continuous beam is fully hardened, the water dripping into the collection box 207 contains cement slurry and particulate matter. This cement slurry, derived from the concrete material of the continuous beam, contains calcium hydroxide, making the wastewater alkaline. Direct dripping onto the soil at the curing site would disrupt the soil's pH balance. However, by recycling the water from the continuous beam using the recovery assembly, it can be reused for spraying the concrete continuous beam without affecting its subsequent use. This saves water resources and reduces the direct impact of water dripping on the soil.

[0030] Of course, alkaline water can damage the recycling components and the transport pipelines and pumps used for the subsequent reuse and maintenance of the recycled water in component 2. This is especially true since most pumps and pipelines are made of metal materials (such as cast iron, steel, and stainless steel), which are easily corroded in alkaline environments. Alkaline water accelerates the breakdown of their surface oxide layers, causing the metal to gradually dissolve and form rust. Prolonged contact with alkaline water can affect the lifespan of the device. Therefore, it is advisable to place an acid neutralizer in the water collection tank to neutralize the alkaline water and reduce its impact on the device.

[0031] Due to the accumulation of substances on the filter screen 303 over long-term use, in one embodiment, the filter box 301 further includes a mounting groove 302, which is disposed on the inner side wall of the filter box 301. The filter screen 303 is slidably connected to the filter box 301 through the mounting groove 302. The filter box 303 also includes a magnet and a magnetic block 304 that cooperates with the magnet. The magnet is embedded in the mounting groove 302, and the magnetic block 304 is embedded on the side of the filter screen 303.

[0032] The recycled water source can be filtered through the filter screen 303. When the filter screen 303 needs to be removed and cleaned after prolonged use, it can be pulled upwards to remove it from the mounting slot 302. After cleaning, the filter screen 303 can be inserted back into the mounting slot 302, where the magnetic block 304 can be magnetically secured to the magnets on both sides of the mounting slot 302, ensuring the stability of the filter screen 303 during use.

[0033] To achieve comprehensive spray curing of the continuous beam, in this embodiment, the curing pipeline includes a main pipeline 203, curing branch pipes 205, and atomizing nozzles 206. The main pipeline 203 is connected to a first water pump 202 and is arranged in a ring above the continuous beam. The main pipeline 203 is connected to a water storage tank 201 through the first water pump 202. The curing branch pipes 205 are arrayed and connected below the main pipeline 203. A water collection box 207 is placed directly below the curing branch pipes 205 to maximize the collection of spray wastewater. The atomizing nozzles 206 are equidistantly arranged on the curing branch pipes. The maintenance branch pipe 205 is arranged in a ring at the bottom end of the continuous beam. The maintenance branch pipe 205 is U-shaped, and the water collection box is located directly below the maintenance branch pipe 205. When maintaining the main body 1 of the continuous beam, water can be injected into the water storage tank 201 first, and then the first water pump 202 can be turned on so that the first water pump 202 can pump water and transport it to the main pipe 203. Then the water will flow into the maintenance branch pipe 205 and be sprayed on both sides and the bottom of the main body 1 of the continuous beam through the atomizing nozzle 206 to achieve maintenance of the main body 1 of the continuous beam.

[0034] Due to variations in the dryness of the weather and the degree of hardening of the concrete continuous beam, the volume of curing wastewater generated will also vary. Therefore, in order to control the amount of water entering the storage tank 201 from the external water source by monitoring the amount of curing wastewater generated, in one embodiment, a third water pump, a controller, and a flow meter are also included. The storage tank 201 is connected to the external water source through the third water pump.

[0035] The first water pump 202, the second water pump 209, the third water pump and the flow meter are electrically connected to the controller and are controlled by the controller.

[0036] The flow meter is used to monitor the water flow rate through the second water pump 209 and transmit it to the controller. The controller controls the operation of the third water pump based on the water flow rate. By monitoring the amount of water flowing through the second water pump 209 through the flow meter, the amount of curing wastewater generated can be monitored. On the one hand, the amount of curing wastewater generated can be known through the workload of the second water pump 209 so as to control the operation of the third water pump. On the other hand, the amount of curing wastewater generated can be used to understand the hardening condition of the concrete continuous beam, because concrete continuous beams with different hardness absorb sprayed water to different degrees.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
