Description

Technical Field

[0001] This utility model relates to the field of guardrail spraying maintenance, specifically to a road concrete guardrail spraying maintenance device. Background Technology

[0002] Spray curing of road concrete guardrails primarily involves using spray curing trucks to keep the concrete surface moist and prevent shrinkage cracks. Existing spray curing trucks straddle the concrete guardrails, directly spraying the surface through nozzles on both sides. Direct spraying helps prevent excessive evaporation, especially when the surface turns white or cracks appear, requiring longer spraying times per session. However, this traditional spray curing method has several drawbacks: the spray curing trucks need frequent movement, resulting in low water utilization; direct spraying easily wastes water and cannot maintain continuous moisture; and the fixed nozzle positions make it difficult to adapt to concrete guardrails of different heights and shapes.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0016] like Figure 1-2 As shown, this application proposes a road concrete guardrail spraying maintenance device, including a concrete guardrail on the side of the road, the upper part of the concrete guardrail is covered with a water-absorbing and moisture-retaining covering layer, the top of the covering layer is provided with a spray pipe arranged along the extension direction of the concrete guardrail, the spray pipe is connected to a water supply system, and multiple clamping and fixing frames are provided on the covering layer.

[0017] As a road safety facility, concrete guardrails require a surface that is kept moist to prevent shrinkage cracks. The covering layer is made of absorbent and moisture-retaining materials, such as non-woven fabric or sponge composites, capable of absorbing and slowly releasing moisture. Sprinkler pipes, preferably made of PVC or PE, are arranged along the entire length of the top of the guardrail, distributing water evenly through drip holes. The water supply system can utilize direct municipal water supply or a combination of a water tank and pump. Clamping brackets, made of metal or plastic, are used to press the covering layer firmly onto the guardrail surface to prevent displacement or detachment.

[0018] This device achieves continuous moisture retention and maintenance of concrete guardrails through a combination of a covering layer and spray pipes. The spray pipes evenly deliver water to the covering layer, which absorbs the moisture and slowly releases it, creating a stable moisturizing environment. Compared to the traditional method of direct spraying by a sprinkler truck, this solution reduces water evaporation loss and improves water resource utilization. The fixing frame ensures a tight fit between the covering layer and the guardrail, preventing displacement of the covering layer due to wind or vehicle vibration. The entire device has a simple structure, is easy to install and maintain, and can achieve long-term effective maintenance of concrete guardrails.

[0019] Furthermore, this application also proposes that the fixing frame includes a horizontal bar arranged on top of the concrete guardrail, with side pressure bars that clamp the sides of the covering layer slidably connected to both ends of the horizontal bar.

[0020] The horizontal bar is made of metal, and its length can be adjusted according to the width of the concrete guardrail. The side clamping bar is slidably connected to the horizontal bar via a sliding sleeve, which has a guide groove to ensure smooth sliding. As a preferred embodiment, the sliding sleeve is made of engineering plastic to reduce frictional resistance. The end of the side clamping bar is equipped with a rubber anti-slip pad to increase the contact friction with the covering layer. Specifically, the clamping force of the side clamping bar can be adjusted by changing the position of the sliding sleeve, maintaining effective fixation even when the thickness of the covering layer changes.

[0021] This technical solution solves the problem of traditional fixing devices being unable to adapt to cover layers of varying thicknesses through an adjustable side pressure bar structure. The sliding connection design between the horizontal bar and the side pressure bar allows the fixing frame to be flexibly adjusted according to the actual thickness / width of the cover layer, ensuring a tight fit between the cover layer and the concrete guardrail surface. Compared to the direct spraying method in the prior art, this fixing structure effectively prevents cover layer displacement and maintains a stable moisture retention effect. As a result, the curing quality of the concrete guardrail is significantly improved, avoiding uneven moisture evaporation caused by a loose cover layer.

[0022] Furthermore, this application also proposes that a sliding sleeve that is slidably connected to the transverse rod is connected to the side pressure rod, and a locking screw is provided on the sliding sleeve.

[0023] Specifically, the sliding sleeve is made of metal or high-strength plastic and has an internal groove that matches the cross-sectional shape of the transverse rod, allowing it to slide freely along the length of the transverse rod. The locking screw has a threaded structure, and its rotation generates radial pressure on the sliding sleeve, thus fixing it to the transverse rod. This is one preferred embodiment.

[0024] Therefore, this technical solution achieves flexible adjustment and reliable fixation of the side pressure bar position through the cooperation of the sliding sleeve and the locking screw. In practice, construction workers can first slide the sliding sleeve to the predetermined position, and then tighten the locking screw to complete the fixation; the entire process can be completed without auxiliary tools. Compared with traditional welding or bolt fixing methods, this structure ensures clamping stability and can quickly adjust the clamping position according to changes in the thickness of the cover layer, effectively solving the problem of insecure fixation of the cover layer caused by deviations in guardrail dimensions.

[0025] Furthermore, this application also proposes that an arc-shaped buckle be provided at the center of the transverse bar to restrict the movement of the sprinkler pipe.

[0026] The arc-shaped buckle is a metal or plastic component with a certain degree of elasticity. Its inner diameter is slightly smaller than the outer diameter of the sprinkler pipe, and it achieves clamping and fixation through elastic deformation. In practice, the arc-shaped buckle can be made of one piece. The inner surface of the arc-shaped buckle can be provided with anti-slip textures or rubber pads to enhance friction. During installation, first place the sprinkler pipe in the preset position on the horizontal bar, and then fasten the arc-shaped buckle from top to bottom to keep the sprinkler pipe stable.

[0027] This technical solution uses arc-shaped clamps to position and constrain the spray pipes, effectively solving the problem of spray pipe displacement caused by water flow impact or external forces in traditional direct laying methods. Specifically, the constraint effect of the arc-shaped clamps prevents axial movement of the spray pipes when the water supply pressure changes, avoiding uneven curing caused by drip hole misalignment. Compared with the mobile spraying method of spray maintenance vehicles in the background technology, this solution achieves precise control of the curing water volume through a fixed spray system combined with a mechanical limiting structure, reducing water waste caused by pipe displacement.

[0028] Furthermore, this application also proposes that the upper part of the spray pipe has several drip holes.

[0029] The drip holes can be arranged uniformly or non-uniformly, and their diameter can be adjusted according to actual spraying needs. The shape of the drip holes can be circular, elliptical, or other suitable shapes. In practice, the spacing between the drip holes can be set to 100-300mm, and the diameter can be set to 2-5mm. The drip holes can be perpendicular to the axis of the spray pipe or inclined at a certain angle to change the direction of water flow. As a preferred embodiment, the drip holes are arranged in a staggered pattern on both sides of the upper part of the spray pipe.

[0030] This technical solution achieves uniform spray curing of concrete guardrails by creating drip holes at the top of the spray pipe. Compared to the direct spraying method in existing technologies, the drip hole design can control the water flow rate, avoiding water waste or uneven curing caused by excessive water flow. Specifically, the drip holes allow the water to be released slowly in a dripping manner, prolonging the contact time between the water and the covering layer and improving the moisture retention effect. Therefore, this solution effectively solves the technical problems of excessive water flow and short-lasting curing effect in traditional spray curing, achieving more efficient water resource utilization and more stable curing results.

[0031] Furthermore, this application also proposes that the water supply system includes a mobile water tank installed on the road, which delivers water along the water supply pipe to the interior of the sprinkler pipe via a water supply pump installed on the side.

[0032] Specifically, the mobile water tank can be made of engineering plastic with wheels, and its volume is designed to be 500-1000 liters depending on the actual maintenance needs. The water pump is preferably a gasoline engine water pump, which is directly driven by the gasoline engine, with a flow rate adjustable from 5-15 L / min. The water supply pipe uses pressure-resistant PE flexible tubing with an inner diameter of 20-25 mm, and is detachably connected to the spray pipe via quick-connect fittings. As a preferred embodiment, the mobile water tank can be equipped with a water level sensor and an automatic power-off protection device, which automatically stops the water pump when the water level falls below a set threshold.

[0033] This technical solution addresses the issues of bulky size and inconvenient movement associated with traditional sprinkler maintenance vehicles through a modular water supply design. The independent water supply unit, consisting of a mobile water tank and a water pump, can be flexibly deployed near the maintenance section as needed, enabling long-distance water delivery via supply pipes. Compared to existing technologies that require the entire sprinkler system to be mounted on a maintenance vehicle, this design significantly reduces equipment weight and ease of movement. The modular structure of the water supply system also facilitates maintenance and repair; if a component malfunctions, it can be replaced individually without shutting down the entire sprinkler system. The adjustable flow rate of the water pump can adapt to the varying water replenishment needs of concrete guardrails under different climatic conditions, and the water pressure can be increased to enhance sprinkler intensity in hot, dry weather.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
