Description

Technical Field

[0001] This invention relates to the field of pavement construction technology, and more specifically, to a method for on-site curing of pavement concrete. Background Technology

[0002] In the field of airport pavement concrete construction, after the concrete is poured and formed, it needs to undergo 14 days of continuous watering curing to ensure that the hydration reaction is fully carried out and ultimately reaches the design strength requirements. Currently, the industry generally adopts the traditional curing method of water truck sprinkling, and its specific operation process is as follows: 1. Water truck refilling: Before curing, the water truck needs to be dispatched to the water source to add water; 2. Round trip operation: After adding water, the water truck travels to the construction area to sprinkle water; 3. Circulation operation: When the water truck runs out of water, it needs to return to the water source to refill.

[0003] The aforementioned traditional maintenance methods have the following drawbacks: 1. Low efficiency: It takes at least 2 hours for a single water truck to go from filling water and driving to the site to completing the watering maintenance, and the coverage area of ​​each operation is limited; 2. Discontinuous water supply: Due to the limited capacity of the water truck, the watering operation is intermittently interrupted, and it is impossible to achieve 24-hour continuous moist maintenance; 3. Quality risk: During the maintenance interval, the moisture on the concrete surface evaporates rapidly, which can easily lead to large humidity fluctuations, induce drying shrinkage cracks, and reduce the durability of the pavement; In addition, the frequent dispatching of water trucks and manual operation significantly increase fuel, equipment and labor costs, especially when maintaining large areas of pavement. Summary of the Invention

[0004] The summary section introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. The summary section of this invention is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to determine the scope of protection of the claimed technical solution.

[0005] To at least partially solve the above problems, the present invention provides a method for on-site curing of pavement concrete, comprising the following steps: Step 1: Based on the concrete construction area on site, plan two maintenance pipeline routes at the edges of both sides of the pavement, and lay a maintenance pipeline structure on each of the two maintenance pipeline routes. Step 2: Insert the pumping pipe of the water pump into the drainage ditch, and connect the outlet pipe of the water pump to the two maintenance pipes through a tee. Step 3: Start the water pump. When the water pump is set up upstream of the drainage ditch, the water pump controls the water pumping pipeline to transport the water source in the drainage ditch to the two maintenance pipeline structures. When the water pump is set up downstream of the drainage ditch, the water pumping pipeline is connected to the water supply pipe to transport the water source in the water supply pipe to the two maintenance pipeline structures. The water is then sprayed onto the pavement concrete in the construction area through multiple outlets of the two maintenance pipeline structures.

[0006] Furthermore, the water supply pipe uses a soft water pipe with a diameter of DN32.

[0007] Furthermore, in step three, when starting the water pump, the output water pressure of the water pump is maintained at 0.4MPa by the variable frequency constant pressure water supply controller. After the maintenance pipeline structure is completely filled with water, the variable frequency constant pressure water supply controller automatically stops the operation of the water pump. When the water outlet valve at the outlet of the maintenance pipeline structure is opened, the variable frequency constant pressure water supply controller detects the pressure change in real time and automatically restarts the water pump, so that the water pump works automatically and continuously supplies water at constant pressure.

[0008] Furthermore, each maintenance pipeline is equipped with multiple water outlets with water valves at intervals. When the water outlet valves are opened, the water pump will automatically start to continuously supply water.

[0009] Furthermore, the maintenance pipeline structure includes: multiple main pipes connected in sequence, with the main pipe at the beginning connected to a tee, and the end of the main pipe at the end sealed.

[0010] Furthermore, the water pumping pipeline includes: a pipe body, one end of which is connected to the water pump inlet, and the other end of which is connected to a water pump filter to filter the water source pumped from the drainage ditch to the water pump.

[0011] Furthermore, the water filter includes: a cutoff plate with a flow outlet in the middle, the two ends of which are fixedly installed on the left and right ends of the inner wall of the drainage ditch; the rear ends of two filter plate structures are movably connected to the two sides of the front side of the cutoff plate, the front ends of the two filter plate structures are rotatably connected to the rear end of a triangular diverter head, the rear end of the triangular diverter head is connected to a guide rod that is laterally slidable in the center hole of the cutoff plate, the rear end of the guide rod is connected to a spherical stop block, and the triangular diverter head and the cutoff plate are connected by a tension spring sleeved on the guide rod; the cutoff plate and the two filter plate structures are arranged in a triangular fit, the cutoff plate is provided with a guide frame for connecting the pipe body, and the lower end of the pipe body is inserted into the filtration area formed between the cutoff plate and the two filter plate structures.

[0012] Furthermore, the filter plate structure includes: a filter plate, the front end of which is rotatably connected to the rear end of the triangular diverter head, and the rear end of which is rotatably connected to a translation baffle. The translation baffle slides and seals the outlet of the interceptor plate. There are two outlets, which are arranged opposite each other on both sides of the flow outlet. The outlets and the flow outlet are connected by a connecting hole for the translation baffle to slide. A translation slider fixed to the top of the translation baffle slides in the translation track at the top of the interceptor plate. A pressure-bearing tension spring is fixedly connected between the translation slider and a fixed plate fixed to the outer side of the top of the interceptor plate.

[0013] Furthermore, the filter plate includes: a filter plate frame and a stainless steel metal filter plate. The two ends of the filter plate frame are rotatably connected to the triangular diverter head and the translation baffle, respectively. The stainless steel metal filter plate is longitudinally inserted into the installation port in the middle of the filter plate frame through the longitudinal insertion port at the top of the filter plate frame.

[0014] Furthermore, the filter plate structure also includes: a portal-shaped slide seat that slides above the filter plate frame, the portal-shaped slide seat being clamped onto the upper surface of the stainless steel metal filter plate, a short shaft being fixedly connected to the top of the portal-shaped slide seat, one end of the short shaft being rotatably connected to the pull rod, the other end of the pull rod being rotatably connected to the bolt post, and the bolt post being threadedly connected to one side of the top of the cutoff plate.

[0015] Furthermore, a sludge scraper is connected to the gantry-shaped slide block, and the sludge scraper slides on the outer surface of the stainless steel metal filter plate.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects: This invention discloses a method for on-site curing of pavement concrete, which significantly improves curing efficiency. By laying a curing pipeline structure along both edges of the pavement, a water pump can be started to continuously supply water for curing, eliminating the need to travel back and forth to the water source, greatly saving time and improving curing efficiency. The curing pipeline structure can be planned and laid according to the on-site concrete construction area, enabling more comprehensive and uniform coverage of the construction area, avoiding the problem of limited coverage area per water truck operation, and allowing for curing of a large area of ​​pavement concrete at once. In addition, this invention uses a water pump to continuously deliver water from the drainage ditch to the curing pipeline structure, and sprays it onto the pavement concrete through multiple outlets, ensuring that the pavement concrete is always in a moist state, providing good conditions for hydration reaction. The continuous water supply curing method can effectively prevent rapid evaporation of moisture from the concrete surface, keeping the concrete surface humidity relatively stable, reducing the occurrence of shrinkage cracks, thereby improving the durability and quality of the pavement.

Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.

[0022] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0023] The following is in conjunction with the appendix Figures 1-17 The present invention will be described in further detail below.

[0024] Example 1: like Figures 1-10 As shown, a method for on-site curing of pavement concrete includes the following steps: Step 1: Based on the concrete construction area on site, plan two maintenance pipeline routes at the edges of both sides of the pavement, and lay a maintenance pipeline structure on each of the two maintenance pipeline routes. Step 2: Insert the pumping pipe of the water pump into the drainage ditch, and connect the outlet pipe of the water pump to the two maintenance pipes through a tee. Step 3: Start the water pump. When the water pump is set up upstream of the drainage ditch, the water pump controls the water pumping pipeline to transport the water source in the drainage ditch to the two maintenance pipeline structures. When the water pump is set up downstream of the drainage ditch, the water pumping pipeline is connected to the water supply pipe to transport the water source in the water supply pipe to the two maintenance pipeline structures. The water is then sprayed onto the pavement concrete in the construction area through multiple outlets of the two maintenance pipeline structures.

[0025] Step 3: When starting the water pump, the variable frequency constant pressure water supply controller maintains the output water pressure of the water pump at 0.4MPa. After the maintenance pipeline structure is completely filled with water, the variable frequency constant pressure water supply controller automatically stops the operation of the water pump. When the water outlet valve at the outlet of the maintenance pipeline structure is opened, the variable frequency constant pressure water supply controller detects the pressure change in real time and automatically restarts the water pump, so that the water pump can continuously supply water at a constant pressure.

[0026] The working principle and technical effects of the above scheme are as follows: First, based on the concrete construction area on site, a maintenance pipeline structure is planned and laid along both edges of the pavement. The pump's suction pipe is inserted into the drainage ditch, and the outlet pipe is connected to the two maintenance pipeline structures via a tee, creating a complete water supply path. This allows water from the drainage ditch to be pumped into the maintenance pipeline structure. When the pump is started, the variable frequency constant pressure water supply controller maintains the pump's output water pressure at 0.4 MPa, ensuring that water flows smoothly through the maintenance pipeline structure with appropriate force, thus filling the pipeline. Once the maintenance pipeline structure is completely filled with water, the variable frequency constant pressure water supply controller automatically stops the pump to avoid over-supply and unnecessary energy consumption. When the outlet valve at the outlet of the maintenance pipeline structure is opened, water flows out, causing a pressure change in the pipeline. The variable frequency constant pressure water supply controller detects this pressure change in real time and automatically restarts the pump, continuously adjusting its operating status to ensure a continuous constant pressure water supply and stable water pressure during the maintenance process.

[0027] In this invention, a method for on-site curing of pavement concrete utilizes a curing pipeline structure laid on both sides of the pavement, along with multiple water outlets. This allows water to be sprayed evenly onto the pavement concrete within the construction area, avoiding the uneven watering problems of traditional curing methods. This ensures that all parts of the pavement concrete are adequately moistened, promoting hydration and improving the overall strength and quality of the concrete. Constant pressure water supply guarantees a continuous and stable water flow during curing, maintaining relatively stable humidity on the pavement concrete surface. This stable humidity environment reduces the risk of shrinkage cracks caused by large humidity fluctuations, improving the pavement's durability and service life. Furthermore, the variable frequency constant pressure water supply controller automatically adjusts the pump's operation based on the actual conditions within the pipeline. It automatically stops the pump once the pipeline is full of water, preventing idling and excessive operation, thus reducing energy waste. When water is needed, it can be activated promptly and supplied at constant pressure, achieving rational energy utilization and reducing energy costs during the curing process.

[0028] When the water pump is installed upstream of the drainage ditch, it controls the pumping pipeline to deliver water from the ditch to the two maintenance pipeline structures. When the pump is installed downstream, the pumping pipeline connects to the water supply pipe, delivering water from the supply pipe to the two maintenance pipeline structures, ensuring a continuous water supply. Finally, the water is sprayed onto the pavement concrete in the construction area through multiple outlets in the two maintenance pipeline structures. Throughout the maintenance process, the variable frequency constant pressure water supply controller automatically detects pressure changes and controls the start, stop, and operation of the water pump, eliminating the need for frequent manual intervention. This not only reduces labor intensity but also improves the accuracy and timeliness of maintenance operations, reducing maintenance quality problems caused by human factors. Compared to traditional water truck sprinkling maintenance methods, this invention reduces the use of water trucks and related fuel, equipment, and labor costs. Simultaneously, the stable constant pressure water supply also reduces equipment damage and maintenance costs that may result from unstable water pressure. Rapid pipeline filling and stable constant pressure water supply can ensure efficient maintenance work, shorten the maintenance cycle, improve construction efficiency, enable pavement concrete to reach the design strength requirements more quickly, and speed up the progress of the entire project.

[0029] Example 2: like Figures 1-10 As shown, each maintenance pipeline structure is equipped with multiple water outlets with valves at intervals. When the valves are opened, the water pump automatically operates, providing a continuous water supply. One water outlet with a valve can be installed every 20 meters or 18 meters, depending on the actual construction conditions. The maintenance pipeline structure includes: multiple main pipes connected sequentially; flanges of adjacent main pipes are bolted together for sealing; the first main pipe connects to a tee; and the last main pipe has its end capped.

[0030] The working principle and technical effects of the above scheme are as follows: Multiple water outlets are spaced apart on each maintenance pipeline structure to ensure that the pavement concrete construction area receives moisture evenly. Water is pumped into the maintenance pipeline structure and sprayed onto the pavement concrete through the spaced outlets, ensuring the entire construction area is adequately moistened and that the hydration reaction proceeds fully in all parts of the concrete. Each outlet is equipped with a corresponding valve, allowing for flexible control over which areas require watering. During actual construction, the maintenance needs of different areas may be adjusted based on factors such as construction progress and the dryness of the concrete. By controlling the outlet valves, targeted maintenance can be applied to specific areas, improving the precision of the maintenance process. The maintenance pipeline structure uses multiple main pipes connected in sequence, facilitating flexible assembly according to the size and shape of the on-site concrete construction area. Main pipes of different lengths and specifications can be combined according to actual needs to adapt to pavement concrete maintenance projects of varying scales. This modular assembly method enhances the versatility and adaptability of the maintenance pipeline structure. The end caps on the main pipes at the ends are used to prevent water from flowing out and wasting water resources. At the same time, the end caps ensure that the water flows in the predetermined direction within the pipe, preventing turbulence and ensuring that water is smoothly and evenly sprayed onto the pavement concrete from each outlet.

[0031] Example 3: like Figures 1-10 As shown, the water pumping pipeline includes: a pipe body 1, one end of which is connected to the water pump inlet, and the other end of which is connected to a water filter 2, so as to filter the water source pumped from the drainage ditch to the water pump through the water filter 2.

[0032] The working principle and technical effects of the above scheme are as follows: Water in drainage ditches typically contains various impurities such as silt, leaves, and small stones. If these impurities directly enter the water pump, they can cause friction against precision components like the impeller and bearings inside the pump. A water filter can prevent larger impurities from entering the pump and causing blockages, ensuring its normal operation, improving equipment reliability and stability, and reducing maintenance interruptions due to equipment failure. Furthermore, water filtered by a water filter has a significantly reduced impurity content. During pavement concrete curing, clean water can contact the concrete more evenly, preventing impurities from adhering to the concrete surface and affecting water penetration and hydration reactions. This ensures the concrete fully absorbs water during curing, resulting in a more complete and uniform hydration reaction, thereby improving the concrete's strength and durability and guaranteeing the quality of pavement concrete curing.

[0033] Example 4: like Figures 1-10 As shown, the water filter 2 includes: a cutoff plate 3 with a flow port 301 in the middle, and the two ends of the cutoff plate 3 are fixedly installed on the left and right ends of the inner wall of the drainage ditch; the two sides of the front side of the cutoff plate 3 are movably connected to the rear ends of two filter plate structures 4, the front ends of the two filter plate structures 4 are rotatably connected to the rear end of the triangular diverter head 5, the rear end of the triangular diverter head 5 is connected to the guide rod 6 which is laterally slidable in the center hole of the cutoff plate 3, the rear end of the guide rod 6 is connected to a spherical stop block, and the triangular diverter head 5 and the cutoff plate 3 are connected by a tension spring 7 sleeved on the guide rod 6; the cutoff plate 3 and the two filter plate structures 4 are arranged in a triangular fit, and the cutoff plate 3 is provided with a guide frame for connecting the pipe body 1, and the lower end of the pipe body 1 is inserted into the filtration area formed between the cutoff plate 3 and the two filter plate structures 4.

[0034] The working principle and technical effects of the above scheme are as follows: The two ends of the intercepting plate 3 are fixedly installed on the left and right ends of the inner wall of the drainage ditch, fixing the entire water filter 2 in a specific position within the drainage ditch to ensure stable filtration of the water flow in the drainage ditch. When the water flows in the drainage ditch, the triangular diverting head 5 first contacts the water flow. Due to its triangular structure, it diverts the water flow to both sides, changing the direction of the water flow. In this invention, the intercepting plate 3 cuts off the water flow in the drainage ditch, and the outlet 301 is located in the middle of the intercepting plate 3, and is situated between the two... Inside the filter plate structure 4, the water flow, after being diverted by the triangular diverter head 5, needs to be filtered through the two filter plate structures 4. Large particles of impurities will be intercepted by the filter plate structures 4, and only the filtered water flow can flow out through the outlet 301. After the large particles of impurities are filtered out by the filter plate structures 4, the water flow enters the filtration zone formed between the interceptor plate 3 and the two filter plate structures 4. At this time, the pipe body 1, in conjunction with the water pump, pumps the water flow in the filtration zone to the maintenance pipeline structure, completing the entire process of water pumping, filtration and transportation.

[0035] In the water filter 2 of this invention, the filter plate structure 4 filters the water flow, effectively intercepting large particulate impurities in the drainage ditch water, such as silt, leaves, and branches. This ensures that the water entering the water pump and maintenance pipeline structure is relatively clean, reducing wear and clogging of the equipment caused by impurities, extending the service life of the equipment, and improving the reliability and stability of the maintenance system. The triangular diverter head 5 diverts the water flow, allowing it to pass through the filter plate structure 4 more evenly, avoiding the situation where the water flow concentrates and impacts a certain point, resulting in poor filtration. At the same time, the intercepting plate 3 intercepts and guides the water flow, making the water flow more orderly during the filtration process, thus improving filtration efficiency and quality.

[0036] In this invention, the intercepting plate 3, the triangular diverting head 5, and the two filter plate structures 4 work together. The triangular diverting head 5 plays a preliminary role in guiding the water flow, evenly directing the water flow to the filter plate structures 4 on both sides. The intercepting plate 3 further restricts the path of the water flow, ensuring that the water flow must pass through the filter plate structures 4 to continue flowing, thus ensuring that the water flow can be effectively filtered. With the cooperation of the triangular diverting head 5 and the intercepting plate 3, the two filter plate structures 4 form a relatively closed filtration area, increasing the contact area and time between the water flow and the filter plates, thereby improving the filtration effect.

[0037] Example 5: like Figures 1-10 As shown, the filter plate structure 4 includes: a filter plate 401, the front end of which is rotatably connected to the rear end of the triangular diverter head 5, and the rear end of which is rotatably connected to a translation baffle 402. The translation baffle 402 slides and seals the outlet 302 of the intercepting plate 3. There are two outlets 302, which are arranged opposite to each other on both sides of the flow outlet 301. The outlets 302 and the flow outlet 301 are connected by a connecting hole 303 for sliding displacement of the translation baffle 402. A translation slider 403 fixed to the top of the translation baffle 402 slides in the translation slide rail 304 at the top of the intercepting plate 3. A pressure-bearing tension spring 405 is fixedly connected between the translation slider 403 and the fixed plate 404 fixed on the outer side of the top of the intercepting plate 3.

[0038] The working principle and technical effects of the above scheme are as follows: The filter plate structure 4 in this invention is not fixed. When the water flow in the drainage ditch is large or the filter plate 401 is clogged and impurities are not discharged smoothly, the water flow after being diverted by the triangular diverting head 5 exerts greater pressure on the filter plates 401 on both sides. Since the rear end of the filter plate 401 is rotatably connected to the translation baffle 402, when the filter plate 401 is under greater pressure, it can drive the translation baffle 402 to slide in the drain port 302 of the intercepting plate 3 towards the connecting hole 303 and the flow port 301, thereby releasing the blockage of the drain port 302 of the intercepting plate 3. When the translation baffle 402 slides, it stretches the pressure spring 405. When the filter plates 401 on both sides approach each other, their front ends drive the triangular diverting head 5 to move away from the intercepting plate 3, and drive the guide rod 6 to slide in the central hole of the intercepting plate 3, keeping the two filter plates 401 in a relatively centered state. At this time, the water flow can be discharged through the drain port 302 to ensure stable water flow. The sliding baffle 402 slides into the connecting hole 303 and the flow port 301. When the inner ends of the two sliding baffles 402 of the two filter plate structures 4 are in contact, the flow port 301 is blocked. At this time, the flow port 301 stops the flow of water. When the water flows through the two drain ports 302, the two filter plate structures 4 are always in an inclined state. At this time, the water flow impacts the two filter plate structures 4, causing the impurities adhering to the two filter plate structures 4 to be washed off and carried away. Water flows out through the drain port 302, thereby alleviating the problem of blockage in the filter plate structure 4. When the water flow rate decreases or the blockage in the filter plate structure 4 is no longer effectively alleviated, the translation slider 403 resets under the elastic force of the pressure spring 405, thereby driving the translation baffle 402 to reset, so that the translation baffle 402 re-seals the drain port 302 and releases the blockage on the flow port 301, allowing the water to be filtered by the filter plate structure 4 and discharged through the flow port 301.

[0039] Example 6: like Figures 1-10 As shown, the filter plate 401 includes a filter plate frame and a stainless steel metal filter plate. Both ends of the filter plate frame are rotatably connected to the triangular diverter head 5 and the translation baffle 402, respectively. The stainless steel metal filter plate is longitudinally inserted into the mounting opening in the middle of the filter plate frame through the longitudinal insertion port at the top of the filter plate frame. The filter plate structure 4 also includes a portal-shaped slide 406 slidably mounted above the filter plate frame. The portal-shaped slide 406 is secured to the upper surface of the stainless steel metal filter plate. A short shaft 407 is fixedly connected to the top of the portal-shaped slide 406. The short shaft 407 is rotatably connected to one end of a pulling rod 408, and the other end of the pulling rod 408 is rotatably connected to a bolt post 409. The bolt post 409 is threadedly connected to one side of the top of the intercepting plate 3. A sludge scraper 410 is connected to the portal-shaped slide 406, and the sludge scraper 410 slides on the outer surface of the stainless steel metal filter plate.

[0040] The working principle and technical effect of the above scheme are as follows: When the filter plate 401 moves, the contact position between the filter plate frame and the portal slide 406 can be changed. The pulling rod 408 plays the role of limiting and increasing the structural strength. The sludge scraper 410 is connected to the portal slide 406. The sludge scraper 410 slides on the outer surface of the stainless steel metal filter plate. When the filter plate frame and the portal slide 406 slide relative to each other, the sludge scraper 410 slides on the outer surface of the stainless steel metal filter plate. With the impact of the water flow, the cleaning effect on the outer surface of the stainless steel metal filter plate is effectively improved. Here, the sludge scraper 410 scrapes away the impurities on the outer surface of the stainless steel metal filter plate, making it less likely to push the impurities into the inner side of the stainless steel metal filter plate, thus preventing the stainless steel metal filter plate from becoming clogged and worsened.

[0041] Example 7: like Figure 11-17 As shown, the present invention provides a method for on-site curing of pavement concrete by laying temporary curing water pipes on-site to continuously supply water to each working face through the pipes.

[0042] The method includes: Step 1: Based on the on-site concrete construction area, plan the maintenance pipeline 030 laying route along the edge of the runway, starting from inside the airport drainage ditch, and setting out water outlets 060 with water outlet valves every 20 meters.

[0043] Step 2: Material preparation: Prepare one three-level switch box, one 010 water pump, one 020 variable frequency constant pressure water supply controller, one variable frequency controller, 1000 meters of 6-meter-long 3-inch HDPE, 166 DN32 water outlets, and a number of bolts. Step 3: Assemble maintenance pipeline 030. At the starting point, install water pump 010 in the airport drainage ditch. Connect the outlet of water pump 010 to a main water supply pipe 040, and then connect it to a tee 050 via flanges to distribute water to two areas to supply the water needs of the pavement on both sides of the ditch. Then, along one side of the runway, splice the main pipes according to the planned laying route. During pipe splicing, bolt the flanges on both sides of the pipes and seal the ends of the pipes to form two maintenance pipelines 030. Connect the two maintenance pipelines 030 to the main water supply pipe 040 via tee 050. Step 4: Start the water pump 010 and control the water supply pressure of the water pump 010 at 0.4MPa. After the water supply main pipe 040 and maintenance pipeline 030 are filled with water, the variable frequency constant pressure water supply controller 020 will automatically control the water pump 010 to stop working. When downstream of the drainage ditch, connect the water supply pipe to the water pump 010 and open the water outlet valve. The water pump will then work automatically and continuously supply water to ensure sufficient water supply for on-site maintenance.
