Description

Technical Field

[0001] The invention belongs to the technical field of automatic concrete spraying and curing, and in particular relates to a full-frame-adaptive coil-type automatic concrete spraying and curing system. Background Art

[0002] In the field of modern construction engineering, concrete structures are widely used. Concrete curing is a key link to ensure the quality, durability and safety of concrete structures. Traditional concrete curing methods mostly rely on manual operations, which not only consumes a lot of manpower and time, but also has uneven curing effects due to human factors, making it difficult to ensure the uniformity and stability of curing. With the development of the construction industry, the requirements for construction efficiency and project quality are constantly rising, and an efficient, intelligent and accurate concrete curing system is urgently needed.

[0003] At present, common concrete curing technologies include manual watering curing, covering and moisturizing curing, and some simple automatic sprinkler devices. Manual watering curing mainly relies on workers to regularly sprinkle water on the concrete surface; covering and moisturizing curing covers the concrete surface with plastic film, geotextile and other materials to retain moisture; some automatic sprinkler devices use a simple timed spraying method, using a timer to control the opening and closing of a water pump or valve to achieve periodic spraying.

[0004] Manual watering maintenance is labor-intensive and the working environment of workers is poor. Due to the instability of manual operation, uneven and untimely watering is prone to occur, resulting in uneven quality of concrete maintenance. Although covering moisturizing maintenance can maintain the humidity of the concrete surface to a certain extent, it cannot accurately control the humidity and temperature, and the concrete maintenance effect for large areas or complex structures is poor. The existing simple automatic sprinkler device lacks intelligent control and cannot adjust the sprinkler parameters in real time according to the actual maintenance needs of the concrete, such as humidity and temperature changes. The sprinkler pipeline layout is single and difficult to adapt to different construction scenarios, which can easily cause waste of water resources and poor maintenance effects. Summary of the invention

[0005] In view of this, the present invention provides a full-frame adaptive coil-type concrete automatic spraying curing system, which can solve the problems of high labor cost, unstable curing effect, inability to adapt to complex construction scenes and waste of water resources in traditional concrete curing methods.

[0006] The present invention is achieved in that:

[0007] The present invention provides a full hall formwork adaptable coiled pipe type automatic concrete spraying curing system, which includes pipelines, joints, nozzles, fixed pipe clamps and coiling devices. The pipelines are fixed on the concrete steel frames through the fixed pipe clamps, and adjacent pipelines are connected and fixed through the joints. The nozzles are connected to the ports of the pipelines, and the nozzles are used to spray water on the surface of the concrete. The side of the nozzle in contact with the concrete surface is provided with a hemispherical water outlet, and the amount of water sprayed by the nozzle on the concrete surface is normally distributed on the plane, and the amount of water sprayed by adjacent nozzles shows an opposite normal distribution curve. The pipelines are wound on the coiling devices, and the coiling devices adjust the tightness of the pipelines through axle wheels.

[0008] On the basis of the above technical solutions, a full hall formwork adaptable coiled pipe type automatic concrete spraying curing system of the present invention can also be improved as follows:

[0009] Among them, the pipelines adopt PVC transparent flexible hoses; the fixed pipe clamps adopt stainless steel elastic fixing clip combinations, including large and small clip pieces, which are docked through nuts.

The large clip piece is designed in an arc shape to fit the surface of the pipeline, and the small clip piece is used for auxiliary fixing. The nut is used to adjust the distance between the large and small clip pieces, so that the fixed pipe clamp is tightly fitted and fixed with the pipeline;

[0010] There are multiple fixed pipe clamps, which are respectively fixed at the turning points, branch points and middle positions of the straight sections of the pipelines to disperse the stress of the pipelines and avoid deformation and fracture of the pipelines due to their own gravity or external forces.

[0011] Furthermore, the joint adopts a positive three-way structure, and the internal channel is designed to be streamlined to reduce the water flow resistance and ensure uniform distribution of water flow to each branch pipeline. The joint is connected to the pipeline through threads, and a rubber sealing ring is arranged at the connection position to enhance the sealing performance.

The middle part of the pipeline is wound on the wire coil, and the wire feeding and winding mechanism and the wire arranging mechanism are arranged on both sides of the wire coil. The pipeline is connected to the wire feeding and winding mechanism and the wire arranging mechanism. The wire feeding and winding mechanism includes a wire feeding mechanism and a wire winding mechanism. The wire arranging mechanism is a wire arranging screw, which is arranged between the wire coil and the wire feeding mechanism and is used to automatically arrange wires following the wire feeding action of the wire feeding mechanism and the wire winding action of the wire winding mechanism;

[0013] The wire feeding mechanism includes a driving gear, a driven gear and a wire feeding motor. The driving gear is fixedly connected to the output shaft of the wire feeding motor, and the wire feeding motor is used to drive the driving gear to rotate. There are two driven gears, which are respectively arranged on both sides of the driving gear, and both driven gears are in contact with the driving gear. The driven gear and the output shaft of the driving gear are connected by a circumferential screw. A pipe pressing wheel is arranged at the top of the wire feeding mechanism. There are two pipe pressing wheels, which are respectively in contact with the driven gears, and the pipeline passes through the space between the pipe pressing wheel and the driven gear.

[0014] The wire winding mechanism includes a wire winding motor and a belt. The wire winding motor is arranged at one side of the wire reel, and the wire winding motor is fixedly connected to the central axis of the wire reel through the belt. The belt connects the output shaft of the wire winding motor and the central axis of the wire reel.

[0015] Further, the shaft wheel is arranged on the wire reel. The shaft wheel includes a convex shaft, a limiting member, a spring and a spring pressing disc.

Concave cavities corresponding to the protrusions are arranged on the shaft wheel, and the protrusions and the concave cavities cooperate with each other. The limiting member is arranged on one side of the convex shaft away from the wire reel. The spring and the spring pressing disc are sequentially arranged between the convex shaft and the limiting member, and are used to adjust the friction force of the spring and the spring pressing disc on the belt through the distance between the limiting member and the wire reel to maintain the consistency of the linear tension.

[0016] Further, a pressure pump is arranged inside the nozzle. The pressure pump includes a housing, a feed inlet, a material outlet, a wire sealing plug structure and a pumping pump. The pumping pump is arranged inside the housing. A liquid flow cavity is arranged between the housing and the pumping pump. One end of the liquid cavity is connected to the feed inlet, and the other end is connected to the material outlet. The feed inlet is used to pump the liquid inside the pipeline into the pressure pump, and the material outlet is used to convey the liquid to the nozzle. The wire sealing plug structure is arranged on one side inside the housing and is used to store wires.

[0017] Further, the nozzle includes a plurality of water outlets, and a pressure increasing swirl structure is arranged inside each water outlet. The pressure increasing swirl structure includes a liquid inlet end and a liquid outlet end. The liquid inlet end is arranged close to the pressure pump, and the liquid outlet end is arranged close to the concrete surface. The cross-sectional area of the liquid inlet end is larger than that of the liquid outlet end.

[0018] Two symmetrical funnel-shaped structures are arranged inside the liquid outlet end. The ends with smaller cross-sectional areas of the two funnel-shaped structures are connected integrally, and the funnel-shaped structures form a fluid channel.

[0019] Furthermore, an anti-backflow structure is provided inside the pipeline. The anti-backflow structure includes two parts, namely a direct-flow part and a bent-flow part. The direct-flow part is arranged at the middle position of the anti-backflow structure, and the bent-flow parts are arranged on both sides of the direct-flow part; the bending degree of the bent-flow part is 160°, and it is connected through the side wall of the direct-flow part; there are 11 bent-flow parts, which are arranged in a cross pattern on both sides of the direct-flow part.

[0020] Furthermore, the cross-section inside the pipeline is V-shaped. The bottom of the V shape is arc-shaped, and the radius is 1 / 3 of the side of the V shape; the included angle of the V shape is 45 - 60°, which is used to control the running path of the flowing liquid inside the pipeline and reduce the resistance of its movement inside the pipeline, precipitate the impurities in the water flow at the bottom of the V shape to avoid clogging the nozzle and prevent damage to the inner surface of the pipeline; the central axis of the cross-section of the pipeline is perpendicular to the horizontal plane, and the projections of the two sides on the horizontal plane are symmetrical about the central axis of the cross-section; on both side walls inside the pipeline, there are protrusions extending towards the central axis symmetrically about the central axis, and the protrusions are used to drive the impurities to the bottom of the pipeline.

[0021] Furthermore, an electromagnetic control valve is provided on the pipeline connecting to the water source. The electromagnetic control valve includes a valve and an electromagnetic coil part connected to the valve. The valve includes a valve sleeve, a spring, a valve core, and a push rod. The spring, the valve core, and the push rod are sequentially arranged inside the valve sleeve. The valve core and the push rod are integrally formed. An output port and a return port are opened on the side wall of the valve sleeve. The output port is composed of four square openings evenly distributed along the circumferential direction. On the outer side of the valve core, there are protrusions extending radially outwards that cooperate with the output port; one end of the valve core is provided with a tubular part for accommodating the spring, and the outer diameter of the spring is slightly larger than the outer diameter of the valve core;

[0022] The electromagnetic coil part is composed of a housing, a coil tubular yoke, and a plunger. The coil is arranged inside the housing, the tubular yoke is arranged on the inner circumferential side of the coil, and the plunger is arranged inside the tubular yoke; the electromagnetic coil part is used to control the opening and closing of the valve.

[0023] The beneficial effects of adopting the above improvement scheme are as follows: Using a PVC transparent hose ensures that the water flow in the system is visible, facilitating the monitoring of the flow state. The pipeline is fixedly connected to the concrete steel frame through stainless steel elastic fixing clips, and can withstand a certain external force without deformation. The middle part of the pipeline is fixed, and the bending parts and branch points are reinforced to avoid deformation or fracture caused by gravity or external force.

[0024] With the hemispherical water outlet design, the spray volume of the nozzle is normally distributed on the plane, and the spray volume of adjacent nozzles presents an opposite normal distribution curve, which effectively ensures uniform spray coverage and avoids uneven moisture distribution on the concrete surface.

[0025] The fixed pipe clamp is composed of stainless steel elastic clips, including large and small pieces. The distance between the clips is adjusted by nuts, which can tightly fix the pipeline and prevent the normal distribution of water flow from being affected by pipeline deformation. The design and adjustment method of the clips enable the pipeline to be stably fixed on the concrete steel frame.

[0026] The joint structure adopts a positive tee structure, and the internal channel is streamlined to reduce water flow resistance and ensure that the water flow can be evenly distributed to each branch pipeline. The joint connects the pipeline through threads and uses a rubber sealing ring to enhance the sealing performance and prevent water leakage.

[0027] The pipeline is wound on the reel and the tension is adjusted by the shaft wheel. The reel design includes a wire feeding and wire collection mechanism and a wire management mechanism to ensure the tension and neat arrangement of the pipeline. The wire feeding mechanism consists of a driving gear, a driven gear and a wire feeding motor. By driving the driving gear to rotate, the wire feeding and wire collection of the pipeline are adjusted.

[0028] The wire management mechanism is composed of a wire management screw, which follows the action of the wire feeding and wire taking-up mechanisms to adjust the arrangement of the pipelines to prevent the pipelines from being tangled unevenly.

[0029] A booster pump is installed inside the nozzle. Water is pumped from the pipe to the booster pump through the extraction pump, and then the booster swirl structure provides high-pressure water flow to ensure that the water flow output by the nozzle is uniform and stable. The booster swirl structure adopts a funnel-shaped design, which can effectively accelerate the water flow and ensure uniform spraying.

[0030] The pipeline is equipped with an anti-backflow structure, which is divided into a straight flow part and a curved flow part, to prevent water from flowing back and affecting the normal operation of the system. The design of the curved flow part helps to guide the water flow and the precipitation of impurities, avoid clogging the nozzle, and ensure smooth water flow.

[0031] The water source part connected to the pipeline is equipped with an electromagnetic control valve, which can automatically control the switch of water flow to ensure the accurate operation of the sprinkler system. The design of the electromagnetic valve includes an electromagnetic coil and a valve assembly. The electromagnetic coil controls the opening and closing of the valve and adjusts the water supply through electromagnetic control.

[0032] Compared with the prior art, the beneficial effects of the full-frame adaptive coil-type concrete automatic spraying and curing system provided by the present invention are:

[0033] (1) The electromagnetic control valve can accurately control the spraying time, frequency and water volume according to the curing requirements of concrete, ensuring that the concrete surface always maintains an appropriate humidity and temperature, effectively improving the strength and durability of concrete. Compared with the traditional film covering and moisture preservation curing method, the strength of concrete at 600℃ is increased by 3 - 5 Mpa.

[0034] (2) The system realizes automatic operation, and the proportion of the automatic operation time in the total curing time reaches more than 90%, reducing manual participation and greatly shortening the curing cycle. At the same time, the quick installation and disassembly design of the coiled hose spraying system and the convenient storage method improve the installation and removal efficiency of the spraying system during the construction process. Compared with the traditional curing method, the curing efficiency is increased by at least 200%.

[0035] (3) It reduces the labor cost and waste of water resources, accurately controls the water spraying volume, and avoids over - curing. By improving the quality of concrete curing, it reduces the defects and rework costs caused by improper curing.

[0036] (4) The flexible pipeline layout and various nozzle selections of the coiled hose spraying system can meet the concrete curing requirements of different building structures such as complex full - hall formwork systems, and have wide applicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0065] 1. Intelligent water valve:

[0066] Select a wireless WiFi gateway intelligent controller. This controller can be used with a 1-to-4 water valve to achieve distributed switch control of multiple water pipes. It has a stable remote control function. In an environment 50 meters away from the device with 3 walls blocking, through the mobile phone APP operation, the average response time is 2 seconds, and the command transmission success rate reaches 99%.

After installation, pair through mobile phone Bluetooth or wireless network to ensure a stable connection between the water valve and the control device. During the debugging process, users can set and test various functions through the mobile phone APP to ensure that the water valve can accurately respond to commands.

[0068] 2. Pipeline: Use a PVC transparent hose as the main water pipe. This hose has good flexibility, the bendable angle is not less than 120°, and there is no rupture after bending 500 times. It has a certain corrosion resistance. After being placed in the simulated construction site environment for 5 days, the material performance has no obvious decline.

[0069] 3. Joint:

[0070] The main connections are made using straight tee joints, and butt joints, end plugs, etc. are used for auxiliary connections. Among them, the 8 / 12 quick-connect type tee joint body is made of high-strength engineering plastic, and its surface has been specially treated for wear resistance. Its interface size is precisely matched for use with 8 / 12mm PVC transparent hoses. On the premise of meeting the use functions, it has the ability of quick installation and disassembly, and the installation time is shortened by at least 30% compared with the traditional method. The joint is firmly connected, and under the water pressure of 0.2 - 0.8 MPa, the leakage rate is lower than 5%. The internal channel of the straight tee joint is designed to be streamlined to reduce water flow resistance and ensure uniform water distribution to each branch pipeline; the butt joint is connected by means of screw tightening, and a rubber sealing ring is provided at the connection part to enhance the sealing performance; the end plug is made of solid plastic material and is tightly connected to the PE hose to prevent water leakage.

[0071] 4. Sprinkler head: A 6.0 large-flow fogging quick-connect copper sprinkler head is arranged every 500mm. The sprinkler head body is made of forged brass and its surface has been nickel-plated to enhance its corrosion resistance. Under the water pressure of 0.3 - 0.6 MPa, the spray coverage radius of the sprinkler head is not less than 0.55 meters, and the deviation of spray uniformity is controlled within ±10%. The internal of the sprinkler head adopts a special swirl structure design, so that the water flow forms a high-speed rotating eddy current inside the sprinkler head, thus realizing a uniform and large-range spray effect. The sprinkler head has good anti-clogging performance. When continuously used for 50 hours in simulated spray water containing certain impurities, the clogging rate is lower than 5%, and the service life is not less than 1000 hours. The sprinkler head is connected to the PE hose through a quick-connect interface, and the installation is convenient. Just insert the sprinkler head into the corresponding interface of the PE hose to achieve a tight connection, and the connection part is well sealed to prevent water leakage.

[0072] 5. Fixed pipe clamp: A stainless steel elastic fixed clip combination is used as the fixed pipe clamp, and the large and small clips are butt-jointed using small nuts. The combination of stainless steel elastic clips with sizes C40*15 wide and C10*10 wide has the best effect. The large clip is 40mm long and 15mm wide, and the small clip is 10mm long and 10mm wide. Both are made of 304 stainless steel, with good elasticity and corrosion resistance. The large clip is designed in an arc shape to better fit the surface of the PE hose. The small clip is used for auxiliary fixation. By butting the large and small clips with a small nut, it can be adjusted according to the diameter of the PE hose to ensure that the clip fits tightly with the pipeline. After installation, the entire spray pipeline is hung on the small head of the pipe clamp to ensure the stability of the pipeline.

[0073] During the use process, first uniformly install pipe clamps on the scaffold at the pre-laid height of the spray pipeline. After installation, the entire spray pipeline is hung on the small heads of the pipe clamps to ensure the stability and safety of the pipeline. Pipe clamps are set at the turning points, branch points, and appropriate positions of the long straight sections of the pipeline to disperse the stress of the pipeline and avoid deformation or fracture caused by the self-weight of the pipeline or external forces. When installing the pipe clamps, ensure that the clamping pieces are closely attached to the pipeline to avoid inconsistent nozzle directions or affecting the fixing effect of the pipeline due to loosening.

[0074] 6. Coiler:

[0075] The overall size of the coiler is 50cm × 30cm × 35cm. The shell is made of high-strength engineering plastic material, with good wear resistance and impact resistance, and can adapt to the complex environmental conditions of the construction site. Its internal structure is designed to specifically fit 8 / 12mm PE water pipes. During the material preprocessing stage, the PE hose already connected with the nozzle and joint can be tightly wound around the coiler. The winding process is smooth and will not damage the hose. The coiler is equipped with a convenient handle and an adjustable axle wheel device. The axle wheel device can flexibly adjust the tightness of the coil to ensure that when winding and unwinding the hose, the pipeline can be closely arranged and the retraction and extension of the pipeline can be easily achieved. At the construction site, the coiler can be directly connected to the floor water valve. Its water inlet is designed to precisely match the water valve interface, with a firm connection and good sealing to avoid water leakage. Construction workers can conveniently move, install, and collect the spray pipeline by pushing the coiler, greatly improving the construction efficiency.

[0076] As Figure 7-8 shown, the third embodiment of the present invention is the installation steps of the spray protection system:

[0077] 1. Draw the layout diagram of the spray pipeline in the construction section

[0078] When drawing the layout diagram of the spray pipeline in the construction section, it is necessary to comprehensively consider the actual situation on site, including the size and shape of the concrete structure and the layout of the construction area. First, according to the construction drawings and on-site measurement data, determine the direction of the spray pipeline and the layout positions of the nozzles. The nozzle spacing should be uniform to ensure comprehensive spray coverage and avoid maintenance blind spots.

[0079] During the drawing process of the layout diagram, refer to the following data:

[0080] (1) When the floor height is 3.0m or less, lay a spray pipeline at a position 500mm below the slab bottom.

[0081] (2) When the floor height is 3.0 - 6.0m, lay a spray pipeline at each of the positions 500mm below the slab bottom and 2500mm above the ground.

[0082] (3) Set the nozzle layout spacing at 500mm intervals

[0083] (4) The distance between the framework and the wall can meet the spraying requirements when it is between 400mm and 600mm.

[0084] (5) When the length of the spraying section exceeds 80m, consider burying reserved pipelines in the floor slab to connect to the floor water intake points, which can be used as the water intake points for the entire layout section to reduce the exposure of exposed wires.

[0085] 2. Prefabrication of spraying pipelines

[0086] In the material preparation stage, prefabricate the nozzles at a spacing of 500mm in advance, connect them to the 8 / 12mm PE hose through tees, and use a coiler to wind and store the connected pipelines to ensure a tight connection with the water inlet of the coiler for convenient on-site installation. When prefabricating, adjust the orientation of the nozzles as early as possible to avoid inconsistent nozzle directions on-site due to pipeline bending, winding, etc.

[0087] 3. Installation of intelligent water valves

[0088] The installation of intelligent water valves should ensure that the connection between the water valve and the water intake point is correct. Usually, threaded connection can be used, and waterproof tape is wound at the threaded part to ensure the water tightness of the interface, and a special pre-filter is connected to prevent blockage of the pipeline and nozzles. After the installation of the water valve is completed, a water pressure test should be carried out to ensure its sealing performance and reliability. The control equipment of the water valve should be paired with the mobile phone APP, connect and adjust the supporting gateway to realize the functions of remote timing and real-time control. According to the pipeline layout and branch situation, a water distribution valve can be set to facilitate the control of the water switch for different sections.

[0089] 4. Installation of special fixed pipe clamps

[0090] The installation of special fixed pipe clamps should be carried out according to the pipeline layout drawing to ensure the stability and safety of the pipelines. The fixed pipe clamps should be evenly distributed, especially at the pipeline turning points, branch points, and appropriate positions on the longer straight sections. During installation, ensure that the clip is closely attached to the pipeline to avoid loosening.

[0091] Use a combination of C40*15 wide and C10*10 wide stainless steel elastic fixed clips with good corrosion resistance as fixed pipe clamps. The large and small clips are butt-connected with small nuts. During use, first install the pipe clamps uniformly on the framework at the pre-laid height of the spraying pipeline. After the installation is completed, the entire spraying pipeline is hung on the small head of the pipe clamp to ensure the stability and safety of the pipeline.

[0092] Add pipe clamps at the pipeline turning points, branch points, and appropriate positions on the longer straight sections to disperse the stress of the pipeline and avoid deformation or fracture caused by the self-weight or external force of the pipeline. When installing the pipe clamps, ensure that the clip is closely attached to the pipeline to avoid inconsistent nozzle directions or affecting the fixing effect of the pipeline due to loosening.

[0093] During pre-assembly, adjust the orientation of the nozzles as early as possible to avoid large inconsistencies in the field nozzles due to reasons such as pipeline bending and winding, and reduce the difficulty of on-site adjustment.

[0094] 5. Installation of spray curing pipelines and nozzles

[0095] The nozzles are pre-assembled at a spacing of 500 mm in advance, connected to the pipeline through a tee, wound and stored using a coiler, and connected to the water inlet of the coiler, which can achieve convenient on-site installation.

[0096] The installation of spray curing pipelines and nozzles shall be carried out according to the layout drawing to ensure the uniform distribution of nozzles and the spray effect. The nozzles should be precisely controlled according to the water demand for on-site curing to achieve the purpose of water conservation and efficient spraying. After installation, local fine-tuning of the nozzle pipeline and spray effect testing shall be carried out to ensure that the nozzles are unblocked and the spraying is uniform.

[0097] For building structures with different storey heights, when the storey height is 3.0 m and below, a spray pipeline is arranged at a position 500 mm below the slab bottom; when the storey height is 3.0 - 6.0 m, a spray pipeline is arranged at a height of 500 mm below the slab bottom and 2500 mm above the ground respectively. The distance between the scaffold and the wall within the range of 400 mm - 600 mm can meet the spray requirements. When the length of the spray section exceeds 80 m, consider burying a reserved pipeline in the floor slab to connect to the floor water intake point, which can be used as the water intake point for the entire section of this layout to reduce the exposure of exposed wires.

[0098] For the column part, prefabricated coiled pipes and nozzles with special arrangement spacing are arranged. The nozzle arrangement spacing is set according to the column side length D + 1000 mm (Note: applicable when D ≤ 800 mm. When D > 800 mm, a single nozzle on one side cannot meet the spray effect), and the nozzles are installed later using extended adjustable-angle nozzles.

[0099] During the formwork construction stage, the distance between the scaffold and the frame column must be strictly required, and it is advisable to be 500 mm, with an allowable deviation of ±50 mm. Otherwise, the requirements of the standardized prefabricated pipeline cannot be met.

[0100] 6. Steam curing

[0101] After the installation of the spray curing pipeline and nozzles is completed, steam curing shall be carried out. According to the curing requirements of the concrete, set the spray time and frequency to ensure that the concrete is properly cured at different stages. The remote monitoring function of the intelligent control system shall ensure the normal operation of the spray system. In an environment with an average construction site temperature of 20 - 30 °C and a humidity of 60% - 80%, it is advisable to set the spray duration to 3 min / time and the spray interval to 15 min. Actually, it can be flexibly adjusted according to the wet and dry degrees of the on-site components.

[0102] 7. Demolition of curing equipment

[0103] After the concrete achieves the expected curing effect (usually continuous moist curing for 14 days), the curing equipment shall be demolished. During the demolition process, careful operation shall be carried out to avoid damaging the spraying equipment. The demolished equipment shall be properly stored, cleaned and maintained for subsequent use.

[0104] Specifically, the principle of the present invention is as follows: When in use, first, lay the PVC transparent hose pipeline in the concrete curing area according to the predetermined design drawings, and ensure the reinforcement and fixation of the distance and bends between the pipelines. Fix the pipeline with stainless steel elastic clips to prevent the pipeline from moving or deforming due to external force or other factors. Install the nozzles as required and adjust their directions and heights. The nozzles should be evenly distributed on the entire concrete surface to ensure that the water mist can cover the entire area and avoid uneven water distribution. Connect the water inlet end of the pipeline to the water source and ensure that the water pressure of the water source is sufficient to support the operation of the system. If the system design includes a booster pump, ensure the normal power supply of the pump. Use an electromagnetic control valve to regulate the opening and closing of the water flow. Start or close the solenoid valve according to the demand, and precisely control the water flow supply through the electric control system. Set the appropriate spraying cycle and duration, usually based on the curing time of the wet surface, to avoid overwatering or insufficient water. After starting the system, the nozzles will start spraying water, and the sprayed water mist will cover the concrete surface. As required, the flow rate, spraying range, spray intensity, etc. of the nozzles can be adjusted to ensure uniform coverage and achieve the best curing effect. Ensure the normal working condition of the booster pump, which can provide stronger water flow pressure to ensure uniform spraying of the nozzles. Regularly check the water flow status of the system to ensure smooth water flow, without blockage or leakage. If it is found that the nozzles are blocked or there are problems with the pipeline, they should be cleaned and maintained in a timely manner. Monitor the coverage of moisture to avoid drought or excessive moisture in local areas due to system failures.
