Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete curing, in particular to a spraying curing device and a concrete pouring and moisture spraying curing process. BACKGROUND

[0002] Concrete is one of the most important engineering materials in modern construction, and the early curing quality after its pouring and molding directly determines the final strength, durability and apparent quality of the structure. During the hardening process of concrete, the internal cement hydration reaction needs continuous and sufficient water.

[0003] If the ambient temperature is high, the air is dry, or the wind speed is large, the water on the surface of the newly poured concrete will evaporate and dissipate rapidly. Once the surface water loss rate exceeds the rate of internal water migration to supplement it, the surface layer of the concrete will stop effective hydration due to water shortage, which may lead to reduced surface strength, fine plastic shrinkage cracks, or even cause penetrating dry shrinkage cracks, thereby seriously damaging the integrity, waterproofness and service life of the structure, and increasing the repair cost in the later stage.

[0004] In order to ensure the full hydration of cement and avoid the generation of harmful cracks, moisture spraying curing has become a widely used and effective key process. This technology aims to maintain the surface layer of the concrete in a fully moist state by continuously or intermittently spraying water mist on the surface of the concrete, to create ideal conditions for hydration reaction and to play a certain role in cooling.

[0005] At present, the conventional concrete moisture spraying curing mainly relies on an automatic spraying system. The system continuously delivers atomized water to the concrete position through the nozzle to meet the curing needs of the concrete. However, since the temperature of the external environment is always changing, in low temperature, high humidity or rainy weather, the fixed flow and frequency of spraying often leads to water surplus, which not only wastes water resources, but also may wash away the concrete slurry, affect the surface strength, or even cause local slurry loss due to excessive water on the surface. In high temperature, strong sunlight, and strong wind weather conditions with strong evaporation, the same amount of spraying is seriously insufficient to compensate for the loss of water due to rapid evaporation, and the concrete surface still faces the risk of dehydration and cracking. SUMMARY

[0006] The present application aims to provide a spraying curing device and a concrete pouring and moisture spraying curing process to solve the problems raised in the background.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solutions: A spraying curing device, comprising: a base and a delivery pipe fixed on the base, and a heat conducting pipe fixed on the delivery pipe; Further comprising: The temperature control and conduction mechanism is arranged in the conveying pipe and connected with the heat conduction pipe, and can act when the temperature in the heat conduction pipe changes and adjust the conduction state of the conveying pipe. The spraying assembly is symmetrically arranged on the outer wall of the conveying pipe, and a plurality of spray heads are arranged on the spraying assembly in equidistant distribution. The water pressure balance mechanism is arranged on the spraying assembly, and a control mechanism connected with the spray head is arranged on the water pressure balance mechanism. The water pressure balance mechanism can adjust the conduction state of the spray head through the spraying assembly, and the spraying range of the spray head can be adjusted through the control mechanism.

[0008] As a further scheme of the present application, the temperature control and conduction mechanism comprises a piston disc slidingly and sealingly connected in the heat conduction pipe, a push rod penetrating the conveying pipe is fixed on the side wall of the piston disc, a first spring is sleeved on the push rod, and the two ends of the first spring are respectively abutted against the piston disc and the conveying pipe. The feeding assembly and the guide assembly are further arranged in the conveying pipe and connected with the push rod.

[0009] As a further scheme of the present application, the feeding assembly comprises a first sealing disc slidingly and sealingly connected with the push rod and fixed in the conveying pipe, a second sealing disc abutting against the first sealing disc is rotatably installed in the conveying pipe, a first conveying groove and a second conveying groove are respectively formed in the first sealing disc and the second sealing disc, and the first conveying groove and the second conveying groove are in conduction cooperation.

[0010] As a further scheme of the present application, the guide assembly comprises a spiral groove formed on the outer wall of the push rod, a rotating sleeve slidingly connected with the push rod is fixed on the second sealing disc, and a limiting block slidingly and fittingly embedded in the spiral groove is fixed on the inner wall of the rotating sleeve.

[0011] As a further scheme of the present application, the spraying assembly comprises a connecting ring fixed on the conveying pipe, a guide pipe and a supporting column are fixed on the connecting ring, the guide pipe is connected with the conveying pipe, a balance pipe is fixed on the end of the guide pipe, the supporting column is fixedly connected with the balance pipe, and the balance pipe is fixedly connected with the spray head.

[0012] As a further scheme of the present application, the water pressure balance mechanism comprises a buffer pipe fixed on both ends of the balance pipe, a displacement disc is slidingly and sealingly connected in the buffer pipe, a movable rod penetrating the buffer pipe is fixed on the side wall of the displacement disc, a limiting ring abuttingly cooperating with the buffer pipe is fixed on the movable rod, a second spring is sleeved on the movable rod, and the two ends of the second spring are respectively abutted against the displacement disc and the inner wall of the buffer pipe.

[0013] As a further scheme of the present application: the water pressure balancing mechanism further comprises a sealing plate fixed on the let go disc and sealingly fitted with the inner wall of the balancing pipe, and the sealing plate is formed with through holes symmetrically distributed and in conductive cooperation with the spray head.

[0014] As a further scheme of the present application: the regulating mechanism comprises a guide rail fixed on the balancing pipe, a movable plate slidingly installed on the guide rail, a push plate fixed at the end of the movable rod, and a connecting rod hingedly connected with the movable plate.

[0015] As a further scheme of the present application: the movable plate is formed with inclined grooves symmetrically arranged, and the spray head is fixed with limiting columns slidingly fitted with the inclined grooves.

[0016] A concrete pouring and moisturizing spray maintenance process comprises the following steps: Step one: water is delivered to the delivery pipe through the pipeline; Step two: when the outdoor temperature changes, the conductive state of the delivery pipe is adjusted under the action of the temperature control conductive mechanism; Step three: the water in the delivery pipe is delivered to the spray assembly through the temperature control conductive mechanism and is sprayed through the spray head for maintenance; Step four: when the water pressure in the spray assembly changes, the water pressure balancing mechanism is driven to move, so that the conductive amount of the plurality of spray heads and the delivery rate remain consistent, and at the same time, the regulating mechanism is driven by the water pressure balancing mechanism to adjust the spraying range of the spray head according to the delivery rate of the spray head.

[0017] Compared with the prior art, the present application has the following advantages: the present application senses the change of the ambient temperature through the heat pipe and drives the internal temperature control conductive mechanism to automatically adjust the sectional area of the water supply channel. When high temperature leads to intensified evaporation, the mechanism increases the opening degree and increases the water supply flow to actively compensate for the water loss. When low temperature slows down the evaporation, the mechanism reduces the opening degree and reduces the water supply flow to avoid water waste and surface over-wetting. In this way, no matter in what kind of climate conditions, the concrete surface can be maintained in the best wet state, completely eliminating the problems of early dehydration cracking or excessive wet flushing caused by the mismatch between the maintenance water amount and the environment. At the same time, the present application ensures the absolute reliability of the maintenance quality and achieves the efficient saving of water resources.

[0018] Through the cooperation of the spray assembly and the water pressure balancing mechanism, the water flow of each spray head can be kept constant. In the process of continuous work, any pressure fluctuation caused by flow change or slight difference in pipeline resistance can be compensated by real-time adjustment of the flow opening degree through the slight displacement of the let go disc, so that the inlet of all spray heads can always maintain a constant and equal pressure, ensuring that the water amount received per unit area at each place along the length and width directions of the maintenance surface is exactly the same, and realizing uniform maintenance without dead angles and differences.

[0019] When the temperature change causes the total water supply adjustment, the corresponding change of the balance pipe pressure not only adjusts the opening of the nozzle, but also synchronously adjusts the spray angle of all nozzles through the regulating mechanism. In high-temperature and large-flow conditions, the nozzle increases the flow and symmetrically expands the deflection angle, which disperses the increased water to a wider maintenance area. In low-temperature and small-flow conditions, the spray range is synchronously narrowed and the water is concentrated. In this way, the water can uniformly cover the target area in different conditions, which not only prevents the runoff or water accumulation caused by water concentration in high-temperature conditions, but also avoids the local insufficient wetting caused by too large range in low-temperature conditions.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0023] In addition, the elements in the present application are referred to as "fixed to" or "provided on" another element, which can be directly on another element or can have a middle element. When an element is considered to be "connected" to another element, it can be directly connected to another element or can have a middle element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0024] Please refer to Figures 1-10 In the embodiments of the present application, a spraying maintenance device comprises: A base 1 and a conveying pipe 2 fixed on the base 1, and a heat pipe 4 fixed on the conveying pipe 2; Further comprising: A temperature control and conduction mechanism arranged in the conveying pipe 2 and connected with the heat pipe 4, the temperature control and conduction mechanism being capable of acting when the temperature in the heat pipe 4 changes and adjusting the conduction state of the conveying pipe 2; A spraying assembly symmetrically arranged on the outer wall of the conveying pipe 2, and a plurality of spray heads 15 being equidistantly arranged on the spraying assembly; A water pressure balance mechanism arranged on the spraying assembly, and a regulating mechanism arranged on the water pressure balance mechanism and connected with the spray heads 15, the water pressure balance mechanism being capable of adjusting the conduction state of the spray heads 15 through the spraying assembly and adjusting the spraying range of the spray heads 15 through the regulating mechanism.

[0025] Specifically, the side wall of the conveying pipe 2 is connected with the water inlet pipe 3 connected with the main water pipeline, which is used for pumping water into the conveying pipe 2. When the concrete is sprayed for maintenance, the spraying amount usually needs to be adjusted according to the light intensity and temperature to prevent the problem of evaporation or excessive spraying due to changes in temperature and light intensity. For this purpose, when the water in the main water pipeline enters the conveying pipe 2 through the water inlet pipe 3, the water in the conveying pipe 2 will be delivered to the spraying assembly through the temperature control conduction mechanism, and under the action of the water pressure balance mechanism, the conduction amount of the spray head 15 is kept consistent. The water in the spraying assembly will be sprayed on the concrete for maintenance through the spray head 15. If the temperature is high during the noon period, in order to avoid the problem of excessive evaporation that leads to ineffective maintenance, the spraying amount needs to be increased. For this purpose, under the action of the temperature control conduction mechanism, the conduction state of the conveying pipe 2 is adjusted to increase the amount of water entering the spraying assembly. At this time, the water pressure in the spraying assembly is increased, thereby driving the water pressure balance mechanism to move, ensuring that the conduction state of the plurality of spray heads 15 is always consistent, and the spraying water pressure is also consistent. At the same time, under the action of the water pressure balance mechanism, the regulating mechanism is also driven to move. Under the action of the regulating mechanism, the spraying range of the spray head 15 is adjusted synchronously, thereby ensuring that the spraying amount is adjusted according to the temperature change, and the spraying maintenance is more uniform.

[0026] Please refer to Figures 1-5 The temperature control conduction mechanism includes a piston disc 8 slidingly and sealingly connected in the heat conducting pipe 4, the side wall of the piston disc 8 is fixed with a push rod 9 penetrating the conveying pipe 2, the push rod 9 is sleeved with a first spring 10, and the two ends of the first spring 10 are respectively abutted with the piston disc 8 and the conveying pipe 2; further comprising a feeding assembly and a guide assembly arranged in the conveying pipe 2 and connected with the push rod 9, the feeding assembly includes a first sealing disc 5 fixed in the conveying pipe 2 and slidingly and sealingly connected with the push rod 9, the conveying pipe 2 is rotatably installed with a second sealing disc 6 abutting with the first sealing disc 5, the first sealing disc 5 and the second sealing disc 6 are respectively provided with a first conveying groove 501 and a second conveying groove 601, the first conveying groove 501 and the second conveying groove 601 are in conduction and cooperation, the guide assembly includes a spiral groove 901 formed on the circumferential outer wall of the push rod 9, the second sealing disc 6 is fixed with a rotating sleeve 7 slidingly connected with the push rod 9, and the inner wall of the rotating sleeve 7 is fixed with a limiting block 701 slidingly fitted with the spiral groove 901.

[0027] In detail, the heat pipe 4 is made of heat conductive material, which has good heat conduction performance. The outer wall of the heat pipe 4 is formed with a through groove 401. The end of the delivery pipe 2 is formed with a key groove. The push rod 9 is fixed with a key matched with the key groove. The cooperation between the key groove and the key ensures that the push rod 9 cannot rotate circumferentially. The piston disc 8 divides the heat pipe 4 into two cavities. The cavity on the side away from the delivery pipe 2 is an expansion chamber. The cavity on the other side of the piston disc 8 is a displacement chamber. The expansion chamber is filled with an expansion gas which can expand when the temperature rises.

[0028] Please refer to Figure 4 In the initial state, the ambient temperature is low. At this time, the piston disc 8 is located at the end of the stroke on the side away from the delivery pipe 2, that is, the distance between the piston disc 8 and the delivery pipe 2 is the largest. The elongation of the first spring 10 in the natural state is larger than the maximum distance between the piston disc 8 and the delivery pipe 2. Therefore, the first spring 10 is in a pre-compressed state and always provides a pushing force to the piston disc 8 in the direction away from the delivery pipe 2. The piston disc 8 will be controlled by the push rod 9 to be located at the end of the stroke on the side close to the heat pipe 4. Under the action of the spiral groove 901 and the limiting block 701, the second delivery groove 601 and the first delivery groove 501 are in an offset state by rotating the sleeve 7 and the second sealing disc 6. That is, the conduction between the first delivery groove 501 and the second delivery groove 601 is the smallest. When it is necessary to spray and maintain, water can be delivered into the delivery pipe 2 through the water inlet pipe 3. The water flow accumulates in the delivery pipe 2 and exerts pressure on the bottom surface of the second sealing disc 6. Since the second sealing disc 6 below the first sealing disc 5 is in the maximum offset position in the initial state, the effective overlapping flow area of the first delivery groove 501 and the second delivery groove 601 on the two sealing discs is the smallest. Therefore, the water flow can only pass through the minimum overlapping cross-sectional area and enter the first delivery groove 501 which is partially communicated with the second delivery groove 601, so as to be delivered to the subsequent spray assembly flow channel at a relatively low basic flow. In this way, the basic water demand for concrete maintenance in a normal or low temperature environment can be met, so as to ensure the maintenance effect while saving water resources.

[0029] When the ambient temperature rises, especially when the direct sunlight causes the temperature in the expansion chamber of the heat pipe 4 to rise, the expansion gas filled in the expansion chamber expands under heat, generating an axial pushing force to push the piston disc 8 to move towards the delivery pipe 2. The pushing force overcomes the initial pre-tightening force of the first spring 10, driving the piston disc 8 and the push rod 9 rigidly connected thereto to axially translate. The movement of the push rod 9 further compresses the first spring 10, so that the reaction force of the first spring 10 is enhanced. The force and the gas expansion force constitute a dynamic balance which changes with displacement, ensuring smooth response of the mechanism and avoiding frequent operation or shaking due to slight temperature fluctuations, Subsequently, the push rod 9 will also drive the screw groove 901 to move, and under the action of the screw groove 901 and the limiting block 701, the axial movement of the push rod 9 is converted into the circumferential rotation movement of the rotating sleeve 7, thereby driving the second sealing disc 6 to rotate. The rotation of the second sealing disc 6 causes the second conveying groove 601 thereon to change in circumferential alignment relative to the first conveying groove 501 on the upper fixed first sealing disc 5. The coincident flow area of the two gradually increases from the initial minimum state, and the continuous increase in flow area directly reduces the local resistance of the water flow through this place. Under the condition that the water inlet pressure is basically constant, the water flow from the main flow passage of the conveying pipe 2 into the spray assembly per unit time is increased. In this way, in the entire spray system, the water supply can be positively and continuously matched with the ambient temperature. The water supply is actively increased during high-temperature periods to compensate for the water loss that may be caused by increased evaporation, thereby automatically maintaining the constant humidity required for concrete surface maintenance under variable environmental conditions, avoiding the risk of early dehydration and cracking of the concrete surface due to insufficient water replenishment during high-temperature and strong sunlight periods in the fixed flow spray, and automatically reducing the water volume during low-temperature periods to prevent excessive spraying and water resource waste.

[0030] Please refer to Figures 1-3 、 Figure 6 、 Figure 7 、 Figure 9 , the spray assembly comprises a connecting ring 11 fixed on the conveying pipe 2, a conduit 12 and a support column 13 are fixed on the connecting ring 11, the conduit 12 is connected with the conveying pipe 2 and the end of the conduit 12 is fixed with a balance pipe 14, the support column 13 is fixedly connected with the balance pipe 14, the balance pipe 14 is fixedly connected with the spray head 15, the water pressure balancing mechanism comprises a buffer pipe 16 fixed at both ends of the balance pipe 14, a let-in disc 17 is slidably and sealingly connected in the buffer pipe 16, an active rod 19 penetrating through the buffer pipe 16 is fixed on the side wall of the let-in disc 17, a limiting ring 1901 abutting against the buffer pipe 16 is fixed on the active rod 19, a second spring 20 is sleeved on the active rod 19, and the two ends of the second spring 20 respectively abut against the let-in disc 17 and the inner wall of the buffer pipe 16, the water pressure balancing mechanism further comprises a sealing plate 18 fixed on the let-in disc 17 and sealingly abutting against the inner wall of the balance pipe 14, and the sealing plate 18 is formed with through holes 1801 abutting against and communicating with the spray head 15.

[0031] Please refer to Figures 1-3 、 Figures 6-10The regulating mechanism comprises a guide rail 1401 fixed on the balance pipe 14, a movable plate 23 slidingly installed on the guide rail 1401, a push plate 21 fixed at the end of the movable rod 19, a connecting rod 22 hinged to the movable plate 23 on the push plate 21, and a limiting column 24 fixed on the nozzle 15 and slidingly fitted into the inclined groove 2301.

[0032] Please refer to Figure 7 Further, when the balance pipe 14 is not filled with water, the yield plate 17 is located at the end of the stroke close to the balance pipe 14, and the yield plate 17 controls the limiting ring 1901 to be in abutment with the buffer pipe 16 through the movable rod 19. At this time, the maximum distance between the yield plate 17 and the inner wall of the buffer pipe 16 is greater than the elongation of the second spring 20 in the natural state, and the second spring 20 always provides a pushing force to the yield plate 17 towards the balance pipe 14. In this state, the push plate 21 controls the movable plate 23 to be located at the end of the stroke away from the conveying pipe 2 through the connecting rod 22, so that the limiting column 24 is located at the end of the stroke on one side of the inclined groove 2301. Under the action of the inclined groove 2301 and the limiting column 24, the plurality of nozzles 15 are in a parallel state, and the spraying range formed by the combination of the plurality of nozzles 15 is the smallest. The yield plate 17 also controls the guide hole 1801 to be in a misaligned state with the nozzle 15 through the sealing plate 18. In this way, the nozzle 15 is in a sealed state. When the spraying maintenance is needed, the water in the conveying pipe 2 enters the balance pipe 14 through the guide pipe 12. Since the guide hole 1801 on the sealing plate 18 is completely misaligned with the inlet of the nozzle 15 in the initial state, the nozzle 15 is effectively sealed by the sealing plate 18. Therefore, the water flow entering the balance pipe 14 cannot be immediately sprayed from the nozzle 15, but rapidly accumulates in the closed cavity of the balance pipe 14, resulting in a continuous increase in the water pressure in the balance pipe 14. The water pressure will directly act on the water-facing surface of the displacement disc 17 and form an axial thrust pushing the displacement disc 17 to move away from the balance pipe 14, which overcomes the initial pre-tightening force of the second spring 20, drives the synchronous axial translation of the displacement disc 17, the sealing plate 18 fixed thereto, and the movable rod 19 and the push plate 21 connected integrally, the movement of the displacement disc 17 compresses the second spring 20, so that the reverse restoring force generated by the second spring 20 increases accordingly, and the displacement disc 17 also drives the sealing plate 18 to move, so that the through hole 1801 gradually moves towards the position matched with the nozzle 15, until the through hole 1801 and the nozzle 15 are in mutual communication, and the balanced water will be uniformly discharged through the plurality of nozzles 15, when the pressure established by the continuous injection of water flow in the balance pipe 14 and the sealing resistance exerted by the second spring 20 through the displacement disc 17 reach dynamic balance, the movement of the displacement disc 17 and the sealing plate 18 stops at a new position corresponding to the current water inflow; When reaching the balance position, there is a stable water pressure in the balance pipe 14, thereby ensuring that the working pressure at the inlet of each nozzle 15 is completely consistent, under the premise that the aperture of the nozzle 15 is consistent, the completely consistent inlet pressure ensures that the spraying rate and atomization effect of all nozzles 15 are highly uniform, thereby ensuring that the water amount and wetness received by each unit area of the concrete curing surface are the same, and achieving uniform curing without difference; In this process, the push plate 21 also controls the movement of the movable plate 23 through the connecting rod 22, thereby controlling the plurality of nozzles 15 to uniformly deviate to both sides with one of the nozzles 15 located at the center position of the balance pipe 14 as the center point through the inclined groove 2301 and the limiting column 24, so as to achieve the effect of automatically adjusting the spraying range of the nozzle 15 according to the spraying water pressure of the nozzle 15; When the ambient temperature changes, the temperature control communication mechanism first acts to change the total water inflow into the system, if the temperature rises, the total water inflow increases, which will temporarily break the original pressure balance in the balance pipe 14, and the higher water inflow will make the pressure in the pipe have a rising trend, thereby pushing the displacement disc 17 to further compress the second spring 20 and increase the alignment area of the through hole 1801 and the nozzle 15; This process on the one hand adapts to a larger flow by increasing the flow area to maintain that the pressure will not be too high; on the other hand, the additional displacement of the displacement disc 17 is transmitted to the movable plate 23 through the movable rod 19, the push plate 21, and the connecting rod 22, so that the movable plate 23 generates greater lateral sliding, the inclined groove 2301 on the movable plate 23 drives the limiting column 24 on each nozzle 15, forcing all nozzles 15 to further deviate to both sides on the basis of the original deviation angle, thereby significantly expanding the overall spraying coverage, the expansion of the spraying range disperses the increased water supply to a wider curing area, avoiding local water accumulation or water flow scouring caused by the concentration of water amount, so that while compensating for high-temperature evaporation, the humidity of the curing surface can still be uniformly distributed; Conversely, when the temperature decreases and the water inflow decreases, the second spring 20 is elastically released and pushes the let-in disc 17 to reset, simultaneously reducing the nozzle opening degree and the deflection angle, and shrinking the spraying range to match the reduced water inflow, so as to maintain the accurate distribution and efficient utilization of the water inflow.

[0033] A concrete pouring and moisturizing spraying maintenance process comprises the following steps: Step one: water is delivered to the delivery pipe 2 through a pipeline; Step two: when the outdoor temperature changes, the delivery pipe 2 is adjusted in the on-off state under the action of the temperature control on-off mechanism; Step three: the water in the delivery pipe 2 is delivered to the spraying assembly through the temperature control on-off mechanism and sprayed through the nozzles 15 for maintenance; Step four: when the water pressure in the spraying assembly changes, the water pressure balancing mechanism is driven to move, so that the on-off amount of the plurality of nozzles 15 and the delivery rate are kept consistent, and at the same time, the water pressure balancing mechanism drives the regulation mechanism to move to adjust the spraying range of the nozzles 15 according to the delivery rate of the nozzles 15.
