Description

Technical Field

[0001] This invention relates to the field of highway construction technology, and in particular to an environmentally friendly construction device and method for highways. Background Technology

[0002] A highway, or expressway for short, is a road specifically designed for high-speed automobile travel. Highways are multi-lane roads with separate lanes for each direction of traffic and fully controlled access. The average daily traffic volume of a highway should ideally be over 15,000 passenger cars, with a design speed of 80 to 120 kilometers per hour. Therefore, the quality of highway construction directly affects the stability and service life of the highway. The highway subgrade, as a crucial component of a highway, bears the load and transfers it underground. The quality of subgrade construction directly impacts the performance of the highway. Because highways need to support heavy vehicles and have high traffic volumes, the load-bearing capacity of the subgrade is severely tested. Consequently, after a certain period of use, highways are prone to cracking, uneven surfaces, and subsidence, placing immense pressure on highway maintenance, disrupting normal traffic flow, and increasing the risk of traffic accidents in cracked or subsided areas.

[0003] Developing highway engineering designs based on eco-friendly principles is a significant trend in our times. Given my country's rapid social and economic development, high-quality highway engineering design is of paramount practical importance. Furthermore, with the deepening of sustainable development concepts, the design and construction of numerous infrastructure projects increasingly demand eco-friendliness. While the construction phase has a short but significant impact on the surrounding environment, traditional extensive construction methods require considerable construction space, generate substantial dust from their materials and processes, have low resource utilization rates, and release harmful substances, affecting vegetation and soil. Therefore, when environmentally friendly alternatives to construction materials cannot be readily available, it is necessary to improve highway construction methods from a technological perspective.

[0004] During highway construction, passing construction vehicles or strong winds stir up dust from the ground, causing dust pollution at the construction site. Simultaneously, dust escapes from the construction sites during processes such as cement, concrete, and asphalt preparation and mixing. Workers within a certain distance of the construction site inhale this dust, impacting their health and affecting the cleanliness of unconstructed sections. Excessive dust can even obstruct the visibility of highway drivers, leading to serious adverse consequences. Existing technologies often rely on water spraying equipment to suppress dust over large areas, achieving some effect. However, this often requires extensive equipment deployment and large water volumes, leading to water waste and insufficient water supply during prolonged construction. Furthermore, large-area water spraying cannot effectively contain the escaped dust within a small area; some harmful dust particles still adhere to water droplets and settle after spreading a certain distance, thus affecting a certain area and contradicting the original intention of environmentally friendly construction. To address these issues, an environmentally friendly highway construction device and method are designed. Summary of the Invention

Detailed Implementation

[0054] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0055] Please see Figure 1-8 An environmentally friendly construction device and method for highways, comprising:

[0056] Water tank 1, there are multiple water tanks 1 arranged in a row, water tank 1 is used to store water for dust suppression;

[0057] A rotatable connecting mechanism is set between two adjacent water tanks 1 to connect the water tanks 1 and allow the two adjacent water tanks 1 to rotate relative to each other. After connecting multiple water tanks 1, the angle between adjacent water tanks can be adjusted. After the angle of multiple water tanks 1 is adjusted, they can form an arc shape as a whole, or even form an enclosed structure when there are enough of them. This can enclose a small area of ​​construction site to suppress dust within a small area, prevent a large amount of dust from escaping or reduce the area of ​​dust escaping. At the same time, the water consumption for dust suppression spraying in a small area is also relatively reduced.

[0058] The interception net is set above the water tank 1 to intercept dust escaping from the construction site. The interception net includes telescopic support rods and a mesh layer 2. The telescopic support rods are arranged in two sets symmetrically on both sides of the upper surface of the water tank 1. The mesh layer 2 is stretched and fixedly connected to the two sets of telescopic support rods. That is, after the two sets of telescopic support rods are extended, they support the mesh layer 2 and allow the mesh layer 2 to unfold. When installing the mesh layer 2 on the telescopic support rods, it can be suspended by setting hooks on the telescopic support rods or fixed by directly binding the corners of the mesh layer 2 to the telescopic support rods. This allows the mesh layer 2 to be disassembled for easy transportation, cleaning, and replacement.

[0059] The device includes atomizing nozzles 3, which spray water mist to help dust settle, resulting in better dust suppression and water conservation. A supporting beam 4 connects the two sets of telescopic support rods on the water tank 1. A four-way connector 5 is installed on the supporting beam 4, and three sets of atomizing nozzles 3 are connected to the four-way connector 5. These three sets of atomizing nozzles 3 spray water mist in three directions: towards the grid layer 2, in the opposite direction to the grid layer 2, and directly above, to intercept dust escaping from the construction site. The four-way connector 5 allows the three sets of atomizing nozzles 3 to work in three different directions. The first stream of atomized water is directed towards the grid layer 2 to wet it and intercept dust; the second stream is directed towards the construction site in the opposite direction to the grid layer 2 to directly intercept dust; and the third stream is directed directly above to increase the enclosure height of the device over the site. This achieves the environmentally friendly construction effect of saving water, suppressing dust, and reducing the dust range.

[0060] Furthermore, casters 6 are provided at the bottom of water tank 1 to facilitate the movement of water tank 1 and to make it easy to adjust the position between each water tank 1.

[0061] Furthermore, a water pump 7 is installed inside the water tank 1. The water pump 7 is connected to the four-way valve 5 through a water pipe so as to pump out the water in the water tank 1 and spray the atomized water through the atomizing nozzle 3 to achieve dust suppression.

[0062] Furthermore, the rotatable connection mechanism includes:

[0063] The first support plate 8 is horizontally fixed on one side of the lower surface of the water tank 1;

[0064] A horizontal opening 9 is provided at one end of the first support plate 8, and a plug 10 is provided at the end position of the horizontal opening 9 to block one side of the horizontal opening 9.

[0065] The first ring 11 has an opening 12, and the first ring 11 extends into the horizontal notch 9 and is fitted onto the plug 10;

[0066] The second support plate 13 is horizontally fixed on the other side of the lower surface of the water tank 1, and the second support plate 13 is correspondingly arranged with the first support plate 8 on the adjacent water tank 1.

[0067] The second ring 14 has one end fixedly connected to the second support plate 13. The second ring 14 is vertically arranged and can enter the inner side of the first ring 11 through the opening 12.

[0068] And a positioning mechanism, which is set on the first support plate 8 to restrict the rotation of the first ring 11.

[0069] Specifically, when connecting two adjacent water tanks 1, the first ring 11 is first rotated so that the opening 12 faces outward from the horizontal notch 9. This allows the second ring 14, which is connected to the second support plate 13, to enter the inner side of the first ring 11 through the opening 12, creating an interlocking connection between the first ring 11 and the second ring 14. The two rings can rotate relative to each other, allowing the adjacent water tanks 1 to rotate relative to each other, achieving an arc-shaped arrangement or even an encircling arrangement. Then, the opening 12 is rotated to the inner side of the horizontal notch 9. A positioning mechanism acts at the opening 12 to restrict the rotation of the first ring 11, ensuring a stable connection between the first ring 11 and the second ring 14.

[0070] Furthermore, the positioning mechanisms include:

[0071] The positioning pin 15 is disposed inside the horizontal notch 9 and slides inside the horizontal notch 9. One end of the positioning pin 15 is used to insert into the opening 12 on the first ring 11 to restrict the rotation of the first ring 11.

[0072] A strip-shaped guide opening 16 is provided on the lower surface of the first support plate 8 and is connected to a horizontal notch 9.

[0073] And to move the slider 17, one end of which is connected to the lower surface of the positioning pin 15, and the other end extends from the strip guide port 16 into the horizontal notch 9.

[0074] Specifically, by sliding the slider 17 within the strip guide opening 16, the positioning pin 15 is guided to move. By pushing the slider 17 outside the first support plate 8 with a finger, the positioning pin 15 is moved into the insertion opening 12 to play a limiting role, thereby restricting the rotation of the first ring 11.

[0075] Furthermore, the telescopic support rod includes a middle support rod 18, a lower support rod 19, and an upper support rod 20;

[0076] Both the middle support rod 18 and the lower support rod 19 are hollow tube structures. The lower support rod 19 passes through the middle support rod 18 and slides inside the middle support rod 18. The upper support rod 20 passes through the middle support rod 18 and the lower support rod 19. The lower support rod 19 and the upper support rod 20 extend from both ends of the middle support rod 18 to extend their working length to both ends of the middle support rod 18. Then, when all three are fully extended, they can support the grid layer 2 at a certain height, so that the grid layer 2 can better suppress the spread of dust.

[0077] The middle support rod 18 has a strip-shaped clearance opening 21 communicating with its interior on one side, and the lower support rod 19 has a guide opening 22 communicating with its interior on one side. Two sets of first limiting sliders 23 are provided at the upper end of the lower support rod 19, located on both sides of the guide opening 22. The two sets of first limiting sliders 23 slide within the strip-shaped clearance opening 21. The lower end of the upper support rod 20 is provided with a second limiting slider 24 that can slide within the strip-shaped clearance opening 21 and the guide opening 22. The upper end of the middle support rod 18 has a first bolt 25 for fastening the lower support rod 19 on its upper side surface. The lower end of the middle support rod 18... A second bolt 26 is provided to fasten the lower support rod 19, thereby achieving height positioning of the middle support rod 18, the lower support rod 19, and the upper support rod 20 through bolt tightening. Specifically, when the telescopic support rod is retracted, the first limiting slider 23 and the second limiting slider 24 slide within the strip-shaped clearance opening 21, which also prevents the lower support rod 19 and the upper support rod 20 from detaching from the middle support rod 18, allowing the lower support rod 19 to fully extend into the middle support rod 18, and then the upper support rod 20 to extend into the middle support rod 18 and continue to extend into the lower support rod 19 to complete the retraction. Therefore, in order to better achieve the continued extension of the upper support rod 20 into the lower support rod 19, the lower end of the upper support rod 20 is designed as a smooth spherical surface to facilitate its extension into the lower support rod 19. The gap between the two sets of first limiting sliders 23 is equal to the guide notch 22 to allow the second limiting slider 24 to pass through.

[0078] The two ends of the support beam 4 are each connected between the two sets of upper support rods 20 in the two telescopic support rods. The support beam 4 is located at the upper end of the upper support rod 20, thereby supporting the four-way 5 and the atomizing nozzle 3 at a higher position.

[0079] Furthermore, the upper support rod 20 is an elastic rubber support rod, which enables the upper support rod 20 to achieve elastic deformation.

[0080] Furthermore, the mesh layer 2 is made of cotton rope mesh. The pure cotton material is absorbent, and the mesh layer 2 is more likely to attract dust after absorbing water.

[0081] Furthermore, a swing rod 27 is provided on both ends of the water tank 1. One end of the swing rod 27 is rotatably connected to the side surface of the water tank 1, and the other end swings on a plane parallel to the side surface of the water tank 1. A traction rope 28 is connected between the swing end of the swing rod 27 and the middle support rod 18 on the corresponding side.

[0082] When the swing rod 27 swings to a vertical position, the traction rope 28 is straightened and the middle support rod 18 remains in a vertical position; when the swing rod 27 swings to a horizontal position, the traction rope 28 pulls the upper end of the middle support rod 18 to make the middle support rod 18 bend.

[0083] A buckle 29 is provided between the swing end of the swing rod 27 and the side surface of the water tank 1 to fix the swing rod 27 in a horizontal state when it swings to a horizontal state.

[0084] Specifically, when the swing rod 27 swings to a horizontal state, it is fixed in a horizontal state by the buckle 29. Then, the traction rope 28 keeps the middle support rod 18 in a bent state. At this time, the grid layer 2 is also in a bent shape with the middle support rod 18. Under the enclosed water tank 1 structure, the upper enclosed opening becomes smaller, making it more difficult for dust to escape. Combined with the atomizing nozzle 3 spraying in three different directions, the construction of environmentally friendly dust suppression is better realized.

[0085] All electrical components in this device are existing technologies, and their electrical connections and controls are common knowledge familiar to those skilled in the art, and will not be described in detail here.

[0086] A construction method based on an environmentally friendly construction device for highways, comprising the following steps:

[0087] Step 1: Determine the construction location and scope of the construction site that will generate dust, and then determine whether this device is suitable for use.

[0088] Step 2: Based on the planned number of water tanks 1 determined in Step 1, multiple water tanks are connected by a rotatable connection mechanism to enclose the construction site. During this process, the water tanks 1 are connected by the rotatable connection mechanism, and the distribution angle between the water tanks can be adjusted.

[0089] Step 3: Unfold the telescopic support poles of the interception net and fix the mesh layer on the telescopic support poles so that the mesh layer is fully unfolded to achieve the best interception effect on dust.

[0090] Step 4: Fill the water tank 1 with water and start the device to spray three streams of atomized water through the atomizing nozzle 3. It is common knowledge that water is pumped by a water pump and atomized by the atomizing nozzle 3. This device is only designed to use the atomizing nozzle 3 to achieve different effects at three different angles.

[0091] Step 5: After the atomizing nozzle 3 in Step 4 is working, direct the first stream of atomized water towards the grid layer 2 to wet the grid layer 2 and thus intercept dust. Direct the second stream of atomized water towards the construction site in the opposite direction to the grid layer 2 to directly intercept dust. Direct the third stream of atomized water towards the top to increase the enclosure height of the device over the site, thereby enabling the device to achieve the environmentally friendly construction effect of saving water, suppressing dust, and reducing the dust range.

[0092] Step Six: After the work is completed, disassemble the device for transportation. The disassembled device is smaller in size, making it easier to load, carry, and transport, which also improves the ease of use of the device.

[0093] In summary, this device, by installing an interception net on the water tank and combining it with nozzles that spray atomized water in three directions, effectively intercepts dust within a certain area. Furthermore, multiple water tanks and the interception net are connected side-by-side via a rotatable linkage mechanism, allowing for adjustment of the distribution angle between the tanks. This effectively encloses the construction site within a small area, preventing dust from spreading widely and settling on surrounding roads and land, while also reducing water consumption. This better achieves environmentally friendly highway construction. Moreover, the device is convenient and flexible to use, making it highly practical and convenient.

[0094] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
