Description

Technical Field

[0001] This utility model relates to the field of highway engineering technology, and more specifically, to an automatic water spraying and humidity control device for highway water-stabilized layer construction. Background Technology

[0002] In highway construction, controlling the moisture content of the water-stabilized layer is crucial for ensuring structural strength and durability. Current construction methods commonly employ sprinkling water on the surface of the water-stabilized layer for moisture control, but this method has significant limitations.

[0003] On the one hand, moisture tends to remain on the surface, failing to penetrate deeper into the soil, leading to internal water shortage and excessive surface moisture. This results in uneven moisture content within the structure, affecting compaction and overall stability. On the other hand, excessive watering easily leads to surface runoff, wasting water resources and potentially eroding surface materials, reducing construction quality. To improve penetration, some construction companies have attempted to insert nozzles or pipes directly into the soil layer. However, because the water-stabilized layer contains gravel and granular materials, the nozzles are prone to clogging, causing uneven watering and even equipment damage, making it difficult to meet the requirements for continuous and stable moisture control. Utility Model Content

[0004] The purpose of this invention is to provide an automatic water spraying and humidity control device for the construction of water-stabilized layers in highways, which can effectively achieve uniform water penetration into the soil layer and reduce the risk of nozzle clogging.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic water spraying and humidity control device for highway water-stabilized layer construction includes:

[0007] The spray bar is hollow and has a pointed cone-shaped bottom. A receiving groove is provided around the bottom of the spray bar, and multiple first nozzles communicating with the interior of the spray bar are provided in each receiving groove. A pipe joint is provided at the top of the spray bar.

[0008] A sliding sleeve is slidably disposed on the spray bar. A deformable piece corresponding to the receiving groove is fixedly disposed at the bottom end of the spray bar. The deformable piece is fitted against the conical sidewall of the spray bar. A sealing strip is fixedly disposed on the inner side of the deformable piece. The sealing strip is inserted into and closed in the receiving groove. The sliding sleeve can slide along the axial direction of the spray bar to drive the deformable piece to open and drive the sealing strip to disengage from the receiving groove.

[0009] A shielding plate, which is arranged in an umbrella shape and sleeved on the spray bar, is movable along the axial direction of the spray bar and fixed to the moved position. The shielding plate is made of a metal plate and can deform under force to change the size of the opening.

[0010] Furthermore, the shielding plate has multiple deformation joints circumferentially arranged around its perimeter, and the top wall of the shielding plate is covered with a rubber layer.

[0011] Furthermore, the shielding plate is fixedly mounted on the slide cylinder, the slide cylinder is slidably sleeved on the slide sleeve, and a rubber ring is embedded in the inner wall of the slide cylinder, the rubber ring abutting against the slide sleeve.

[0012] Furthermore, the spray bar has a plurality of second nozzles circumferentially opened near its lower end, and the sliding sleeve has a third nozzle corresponding to each of the second nozzles. When the sliding sleeve slides along the axial direction of the spray bar to a predetermined distance and opens the receiving groove, the third nozzle communicates with the second nozzles.

[0013] Furthermore, the spray bar is provided with a limiting ring to restrict the sliding sleeve from sliding to a predetermined distance.

[0014] Furthermore, a blade is fixedly provided on the back side of each of the deformable pieces.

[0015] Furthermore, the blade has a deformation notch at the bending position of the deformable piece.

[0016] Furthermore, the pointed portion of each deformable piece near the spray bar is also pointed.

[0017] Furthermore, the third nozzle is inclined toward the ground and is an atomizing nozzle.

[0018] Furthermore, the pipe joint is a rotary joint.

[0019] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0020] 1. This utility model, through the cooperation of a deformable plate and a sealing strip at the bottom of the spray bar, can seal the receiving groove and nozzle when not in operation, preventing soil particles, sand, and other impurities from entering the spray bar and causing blockage. When the sliding sleeve moves down, driving the deformable plate to open, the sealing strip disengages from the receiving groove, the nozzle is opened, and the opening of the deformable plate can also provide some support to the surrounding soil or sand, thereby forming a stable water outlet channel, ensuring that the water flows smoothly and penetrates evenly into the water-stabilized layer. This structure can effectively avoid nozzle clogging problems and improve the uniformity and penetration effect of water spraying.

[0021] 2. This utility model utilizes an umbrella-shaped metal plate structure for the shielding plate, which can shield and guide the sprayed water during water spraying, preventing water from splashing directly onto the soil surface or causing excessive runoff. Simultaneously, the shielding plate can be deformed and adjusted in size to adapt to different construction conditions, achieving control over the spraying area and guiding the water flow direction. This design helps improve water utilization efficiency, ensuring concentrated water infiltration into the target area, thereby further enhancing the moisture control effect.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] The following is for reference Figures 1-4As shown in the illustration, and further explained with reference to specific embodiments, this embodiment provides an automatic water spraying and humidity control device for highway water-stabilized layer construction, including a spray bar 100. The spray bar 100 is a circular rod, hollow in shape, with a pointed cone-shaped bottom end. A receiving groove 110 is provided circumferentially at the bottom of the spray bar 100. The receiving groove 110 is an elongated groove, and each receiving groove 110 has multiple first nozzles 120 communicating with the interior of the spray bar 100. A pipe joint 140 is provided at the top of the spray bar 100. The pipe joint 140 is a rotary joint for easy connection to pipes.

[0030] The spray boom 100 is also equipped with an operating lever 500 welded to its top, facilitating the gripping and insertion or rotation of the spray boom 100 by operators. The spray boom 100 is preferably made of corrosion-resistant metal to ensure strength and durability under high-pressure water flow and abrasive particle environments. The internal water passage of the spray boom 100 is connected to the pipe joint 140. The rotary joint reduces the torsional stress of the external pipeline during docking or flipping, facilitating quick connection and disassembly on site.

[0031] Reference Figure 2 and Figure 4 As shown, the sliding sleeve 200 is slidably mounted on the spray bar 100, and an operating lever 500 is also welded onto the sliding sleeve 200 for easy gripping and pushing by the operator. A deformable piece 210 corresponding to the receiving groove 110 is integrally provided at the bottom end of the spray bar 100. The deformable piece 210 is fitted against the conical sidewall of the spray bar 100, and a sealing strip 211 is fixedly provided on the inner side of the deformable piece 210. The sealing strip 211 is inserted into and sealed within the receiving groove 110. The sliding sleeve 200 can slide along the axial direction of the spray bar 100 to drive the deformable piece 210 to open and cause the sealing strip 211 to disengage from the receiving groove 110. To achieve reliable closure and opening, the deformable plate 210 should preferably be made of a metal material with elastic recovery capability (such as spring steel with good resilience), and the sealing strip 211 should preferably be made of a wear-resistant elastic material (such as rubber or elastic polymer). The shape of the sealing strip 211 can be a lip-shaped or T-shaped insert to form an effective seal with the receiving groove 110 in a static state, preventing fine particles and dirt from entering the first nozzle 120. The axial displacement of the sliding sleeve 200 can be achieved by manually pushing the operating rod 500 or by cooperating with the mechanical drive component to achieve a controllable opening stroke.

[0032] The shielding plate 300 is arranged in an umbrella shape and fitted onto the spray boom 100. The shielding plate 300 can move along the axial direction of the spray boom 100 and be fixed in its moved position. The shielding plate 300 is made of metal plate and can deform under force to change its opening size. Since the shielding plate 300 is located outside the soil layer, its function is to shield, guide, and buffer the sprayed water flow, thereby reducing splashing and runoff, and facilitating the concentration and guidance of the water flow to the soil surrounding the spray boom 100. A lockable positioning element or fastening structure is provided between the shielding plate 300 and the spray boom 100 to facilitate adjustment of the shielding plate 300's position at different construction depths and spray radii. The material and thickness of the shielding plate 300 must balance deformability and durability, and also consider ease of on-site replacement and maintenance.

[0033] As an optional embodiment, the shielding plate 300 has multiple expansion joints 310 around its perimeter to accommodate deformation. The top wall of the shielding plate 300 is covered with a rubber layer 320, which serves to block water and accommodate deformation. The arrangement and spacing of the expansion joints 310 should ensure that the shielding plate 300 can be controllably folded in the expected direction without cracking under stress. The rubber layer 320 not only improves the shielding and guiding capacity of water flow but also provides protection and buffering for the contact surface, reducing wear between the metal and the soil surface. The rubber layer 320 material should preferably be an aging-resistant and wear-resistant elastomer, and can be reliably bonded to the metal plate using layered bonding or hot-pressing lamination processes.

[0034] Furthermore, the shielding plate 300 is fixedly mounted on the slide cylinder 330, which is sleeved on the sliding sleeve 200. A rubber ring 331 is embedded in the inner wall of the slide cylinder 330, and the rubber ring 331 abuts against the sliding sleeve 200 to achieve positioning. The slide cylinder 330 serves as a support and moving part of the shielding assembly, and its length can be designed to be relatively long to cover several third nozzles 220 or to cooperate with the sliding sleeve 200 to form an adjustable closed length. The slide cylinder 330 and the sliding sleeve 200 form a hydrostatic seal and friction fit through the embedded rubber ring 331, thereby preventing water leakage along the axial direction and providing a certain positioning resistance to fix the position of the slide cylinder 330. The position and cross-sectional shape of the rubber ring 331 need to be selected according to the working pressure and abrasion conditions to ensure that the sealing performance is maintained after multiple movements.

[0035] As an optional embodiment, the spray bar 100 has multiple second nozzles 130 circumferentially arranged near its lower end. A third nozzle 220 is provided on the sliding sleeve 200 corresponding to each second nozzle 130. When the sliding sleeve 200 slides along the axial direction of the spray bar 100 to a predetermined distance and opens the receiving groove 110, the third nozzle 220 communicates with the second nozzles 130. Thus, the second nozzles 130 and third nozzles 220 are not initially opened. This segmented nozzle arrangement allows for phased or zoned spraying: after the spray bar 100 is inserted and reaches a predetermined depth, the sliding sleeve 200 shifts and simultaneously opens the first nozzle 120, connecting the second nozzle 130 and the third nozzle 220, forming a seepage path from the inside out and from the bottom up. This reduces the risk of water accumulation on the surface causing runoff and allows for a moisture control process that first wets the deeper layers and then addresses the surface.

[0036] It should be noted that, due to the relatively long length of the slide cylinder 330, its position can be adjusted to close the third nozzle 220, or open it as needed. Simultaneously, the shielding plate 300 provides a shielding function. The mobility of the slide cylinder 330 allows for zone selection: by pushing or pulling the slide cylinder 330 to cover or expose different groups of third nozzles 220, the spray ring to be opened can be selected according to construction needs, facilitating localized strengthening or weakening of humidity control. To ensure precise positioning, a scale, groove, or quick-locking mechanism can be installed between the slide cylinder 330 and the sliding sleeve 200 for rapid on-site adjustment and resetting.

[0037] As an optional embodiment, the spray bar 100 is provided with a limiting ring 400 to restrict the sliding sleeve 200 from sliding to a predetermined distance. The limiting ring 400 is provided to prevent the sliding sleeve 200 from overtraveling. The limiting ring 400 can adopt an adjustable retaining ring or a threaded locking structure. By adjusting the limiting position, it can adapt to the opening requirements of different soil types and construction depths. Moreover, the material and fixing method of the limiting ring 400 must ensure stability and reliability during the opening and closing cycle.

[0038] Reference Figure 2 , Figure 3As shown, each deformable piece 210 has a fixed blade 212 on its back side, which enhances its ability to penetrate underground. After deformation, the deformable piece 210 can open up more soil, preventing blockage of the first nozzle 120. The blade 212 has a deformation notch 2121 at the bending position of the deformable piece 210 to accommodate deformation. The blade 212 is fixed to the back of the deformable piece 210 by welding or riveting. The cutting edge of the blade 212 is heat-treated to increase its hardness, which is beneficial for penetrating cohesive or gravelly soil. The deformation notch 2121 reserved in the bending area of ​​the blade 212 allows the blade 212 to undergo controllable deformation when the deformable piece 210 opens, avoiding stress concentration or breakage, while ensuring that the blade 212 can continue to separate and open up the surrounding soil in the open state.

[0039] Furthermore, each deformable piece 210 has a pointed tip near the nozzle 100 for easy insertion into the soil. The pointed deformable piece 210 serves as a guide and cutter during initial insertion, and together with the blade 212, it reduces the insertion force. Driven by the sliding sleeve 200, it completes the opening action with relatively small kinetic energy, thereby forming a relatively stable water spray cavity after opening, which facilitates water infiltration and lateral diffusion, and reduces the probability of the nozzle being blocked by particles.

[0040] As an optional embodiment, the third nozzle 220 is inclined towards the ground and is an atomizing nozzle. The inclined arrangement of the atomizing third nozzle 220 allows the sprayed water to form fine droplets that diffuse along the soil surface or in the intended direction. These fine droplets have a larger specific surface area and better adsorption, which is beneficial for forming a continuous wetting layer between soil particles, reducing surface runoff and improving infiltration efficiency. The atomizing nozzle can be equipped with a backwashing function to self-clean through short-term high-pressure flushing in case of clogging risk, extending the continuous working time on site.

[0041] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
