Abstract
Description
Technical Field
[0001] This utility model relates to an intelligent maintenance vehicle for waterproof concrete on high-speed railway bridge decks, belonging to the technical field of road and bridge construction equipment. Background Technology
[0002] In high-speed railway construction projects, waterproofing of the bridge deck is crucial. The bridge surface between the high-speed railway track slabs needs to be waterproofed, which generally involves spraying waterproof coating, laying waterproof membrane, and then laying waterproof concrete. After the concrete is laid, it needs to be cured by watering.
[0003] Due to the extremely narrow construction area on high-speed railway bridge decks, only about 2 meters wide, it is unsuitable for large-scale equipment construction. Currently, the curing of waterproof concrete on high-speed railway bridge decks still largely relies on manual labor, a traditional method with significant drawbacks. Firstly, manual curing is inefficient and cannot meet the demands of large-scale, fast-paced construction in high-speed railway projects. Secondly, the arbitrariness and lack of standardization in manual operation can easily lead to uneven coverage of the concrete surface, resulting in localized neglect or over-curing, which in turn affects the concrete strength and waterproofing performance. Furthermore, the complex construction environment of high-speed railway bridge decks, requiring manual curing operations at heights and on narrow surfaces, exposes workers to safety risks such as falls from heights, posing significant safety hazards. Additionally, traditional curing methods often involve direct water spraying, resulting in severe water waste and contradicting green construction principles. Utility Model Content

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0028] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", "front end", "rear end", "both ends", "one end", "the other end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0029] This utility model is an intelligent maintenance vehicle for waterproof concrete on high-speed railway bridge decks. The vehicle has a small structural size and is mainly suitable for the maintenance of waterproof concrete in the narrow area between track slabs on high-speed railway bridge decks. The maintenance is achieved by spraying water.
[0030] As shown in the figure Figure 2 As shown, the maintenance vehicle includes a main support frame 3, a traveling seat 1, and a spraying assembly. Traveling wheels 2 are installed at both ends of the main support frame 3, which drive the entire machine. The spraying assembly is mounted on the main support frame 3 and is used to spray water onto the concrete bridge deck for curing.
[0031] Regarding the installation of the traveling wheels 2, traveling seats 1 can be installed at both ends of the main support 3, and the traveling wheels 2 can be mounted on the traveling seats 1. Alternatively, the traveling seats 1 can be integrated with the main support 3 as a single unit. (Specific details are as follows...) Figure 6 As shown. Figure 6 The two ends of the main support frame are covered with plates, which also cover the main support frame.
[0032] Specifically, the spray assembly includes a water tank 4 and several nozzles 5. Multiple nozzles 5 are provided, and the nozzles 5 are connected to the water tank 4 via pipes. Typically, the nozzles 5 are mounted on the pipes. A water pump is installed at the outlet of the water tank 4, and the pipes are connected to the water pump. The nozzles 5 are capable of spraying water mist.
[0033] In specific implementation, such as Figure 3 As shown, nozzles 5 are located on the lower end face of the main support 3, and are mounted on a pipe section fixed to the lower end face of the main support 3. Furthermore, to ensure water spraying at all locations, nozzles 5 are arranged in rows, with multiple rows typically consisting of 2-3 rows. The nozzles 5 in each row are evenly spaced. Adjacent rows of nozzles 5 are staggered longitudinally to achieve comprehensive water spraying. When setting multiple rows of nozzles 5, the end of the pipe branches into multiple pipes to accommodate the various rows of nozzles 5.
[0034] The maintenance vehicle of this technical solution can also be equipped with a water spray gun 8, which is used to spray water to replenish areas that have not been sprayed. Figure 4 As shown, the water gun 8 is also connected to the water tank 4 via a pipe. It can share the pipe and water pump with the nozzle, or it can have its own pipe and water pump. The water gun 8 can be handheld. The operator stands on the platform 7 at the rear and uses the water gun 8 to spray water to replenish any areas that are short of water. Usually, the aforementioned nozzles can ensure effective spraying, and the water gun 8 is an optional configuration. Figure 4 The image shows a water gun 8, which is connected to a water tank via a pipe (the pipe is not shown in the image).
[0035] This intelligent maintenance vehicle typically has a platform frame 7 installed on the front end of the main support 3, or a platform plus 7 can be installed on the rear end of the main support. Workers can repair any defective areas in real time on the front platform frame 7. A covering component is installed on the rear platform frame 7 for the application of geotextile or curing membrane.
[0036] Specifically, such as Figure 5 As shown, the paving assembly includes a paving support 10 for holding the rotating reel 8 and a guide roller 9 for guiding the paving material. The rolled paving material is placed on the paving support 10 by rotating the reel 8. Then, during operation, the paving material is released and adhered to the concrete bridge deck via the guide roller 9. Applying a curing membrane or geotextile promptly after water spraying can improve the paving effect and thus enhance the concrete curing process.
[0037] The main support frame 1 of this maintenance vehicle is equipped with a large-capacity water tank, which can be 1000L, to ensure an ample water supply. Atomized spraying via nozzles achieves water conservation.
[0038] The maintenance vehicle's wheels are driven by a motor and a reducer, and the control system is equipped with a remote control, enabling remote control operation.
[0039] When in operation, the maintenance vehicle travels along the retaining wall on the side of the high-speed rail track slab. Rubber wheels are preferred for the traveling wheels. Furthermore, anti-collision wheels 11 are installed on the outer sides of both ends of the main support 1, with at least two anti-collision wheels 11 on each side, to ensure that the maintenance vehicle can travel smoothly and normally on the retaining wall.
[0040] This utility model of a high-speed railway bridge deck waterproof concrete intelligent curing vehicle has a compact structure, making it suitable for construction in confined areas on high-speed railways. By setting multiple atomizing nozzles, it achieves a highly efficient and water-saving spraying effect. Uniform atomized spraying keeps the concrete humidity at ≥90%, reducing shrinkage cracks by 80%. In conjunction with geotextile covering, it inhibits moisture evaporation and increases the concrete compressive strength to 115% of the design value, greatly improving the construction quality.
[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
