Description

Technical Field

[0001] This invention relates to the field of road construction engineering, and specifically to a device and method for treating transverse joints in road construction. Background Technology

[0002] During the construction of the base or subbase of highway pavement, construction may be interrupted for more than 2 hours due to construction organization, section division, work surface conversion, or other reasons. In this case, it is necessary to set up construction transverse joints in a standardized manner to ensure a smooth connection during subsequent construction, thereby guaranteeing the flatness of each structural layer of the pavement and the overall driving comfort of the road surface.

[0003] In the later stages of road base construction, transverse joints need to be treated. Currently, the common method for treating these transverse joints is to use a filling device to inject asphalt material into the transverse joint. Traditional construction transverse joint filling devices have limited functions, require operators to hold the spray pipe, cannot control the distance between the asphalt nozzle and the transverse joint, and can only pour in a small amount of asphalt each time. The asphalt is relatively viscous, the filling speed is slow, and the filling requires too much experience, making it inconvenient to use. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a device and method for treating transverse joints in road construction. This invention addresses the common problem that existing methods for treating transverse joints involve using a filling device to inject asphalt material into the joint. Traditional transverse joint filling devices are limited in function, cannot control the distance between the asphalt outlet and the joint, can only inject a small amount of asphalt at a time, and have a slow filling speed due to the viscous nature of the asphalt. Furthermore, the filling process requires a high level of experience and is not convenient to use.

[0005] The technical solution to achieve the above objectives is:

[0006] This invention provides a device for treating transverse joints in road construction, comprising:

[0007] Supply section, the supply section being used to contain and fill materials;

[0008] The spraying section includes a spray pipe communicating with the supply section. A spray head is sleeved on the end of the spray pipe away from the supply section. A spring is sleeved on the outside of the spray pipe and the spray head. The two ends of the spring are fixedly connected to the spray pipe and the spray head, respectively.

[0009] A further improvement of the road construction transverse joint treatment device of the present invention is that the spraying head includes: a first connecting sleeve and a movable frame;

[0010] The first connecting sleeve is sleeved on the outer side of the injection pipe at the end away from the supply part, and the first connecting sleeve can slide relative to the injection pipe;

[0011] The spring is sleeved on the outside of the first connecting sleeve, and one end of the spring is fixedly connected to the first connecting sleeve.

[0012] The mobile frame is sleeved on the outside of the first connecting sleeve, and the mobile frame can move on the road surface.

[0013] A further improvement of the road construction transverse joint treatment device of the present invention is that a second connecting sleeve is provided at the end of the spray pipe away from the supply part;

[0014] One end of the spring is connected to the outside of the second connecting sleeve;

[0015] The first connecting sleeve is slidably disposed outside the second connecting sleeve.

[0016] A further improvement of the road construction transverse joint treatment device of the present invention is that the axial length of the second connecting sleeve is greater than the axial length of the first connecting sleeve.

[0017] A further improvement of the road construction transverse joint treatment device of the present invention is that the movable frame includes: a connector fixedly sleeved on the outside of the first connecting sleeve and two movable wheels rotatably connected to both sides of the connector.

[0018] A further improvement of the road construction transverse joint treatment device of the present invention is that the movable frame includes: a connector slidably sleeved on the outside of the first connecting sleeve and two movable wheels rotatably connected to both sides of the connector.

[0019] A further improvement of the road construction cross joint treatment device of the present invention is that the spray head further includes a cleaning part disposed on the front side of the first connecting sleeve, which can clean the road surface.

[0020] A further improvement of the road construction transverse joint treatment device of the present invention is that the supply unit includes: a movable base and a storage bin disposed on the base;

[0021] The storage bin is connected to the injection pipe and provides filling material to the injection pipe.

[0022] A further improvement of the road construction transverse joint treatment device of the present invention is that the supply unit further includes: a jet pump, the input end of which is connected to the storage bin, and the output end of which is connected to the jet pipe.

[0023] The present invention also provides a method for treating transverse joints in road construction, comprising the following steps:

[0024] The operator holds the spray pipe and points the spray head toward the construction joint, applying downward pressure to make the spray head press against the road surface at the construction joint.

[0025] The supply unit delivers filling material to the spray head, and the spray head then delivers the filling material into the transverse slit.

[0026] When the operator feels the force of the filling material acting on the spray pipe while holding the spray pipe, the operator moves the spray pipe forward along the direction of the construction joint to inject the filling material into the next area until the current joint construction is completed.

[0027] The beneficial effects of this invention are: the operator aligns the spraying head with the transverse seam to be constructed, and after the spraying head is supported against the transverse seam, it delivers filling material into the transverse seam. After the filling material fills the transverse seam, it will push against the spraying head in the opposite direction. When the operator feels the pressure of the sprayed filling material acting on the spraying head, it means that the transverse seam treatment is completed. The placement position of the spraying head and the amount of filling material sprayed can be controlled more easily, making the treatment of the transverse seam smoother and faster.

[0034] In road construction, the treatment of transverse joints is a crucial step in ensuring road quality and smoothness. Current common methods for treating transverse joints mainly rely on manual operation or simple mechanical filling devices. These devices typically achieve filling by directly pouring or squeezing molten asphalt material into the transverse joint. However, this method has several limitations:

[0035] Traditional filling devices mostly only have simple conveying functions, lacking precise control and adjustment capabilities, and cannot adapt to the treatment needs of transverse joints of different widths and depths. Because the device cannot precisely control the distance between the asphalt nozzle and the transverse joint, construction workers often need to make multiple attempts and adjustments to ensure accurate filling, which is both time-consuming and labor-intensive. Asphalt itself is quite viscous, and the pouring speed is limited by the material's fluidity and equipment performance, resulting in only a small amount of asphalt being poured in at a time, requiring repeated operations to complete the filling of the entire transverse joint, leading to low construction efficiency. The construction effect largely depends on the operator's experience and skill; for inexperienced construction workers, it is difficult to guarantee the uniformity and quality of the filling.

[0036] To overcome the shortcomings of the prior art, this invention provides a road construction transverse joint treatment device, the core of which lies in the introduction of a retractable spray head design. This head automatically adjusts its position according to the depth of different transverse joints, ensuring that asphalt material is precisely aligned and filled into the joint. Through the retractable spray head design, this invention can accurately deliver the filling material into the transverse joint in one go, reducing the number of repeated adjustments and fillings, and significantly improving construction efficiency.

[0037] After the spray nozzle fills the transverse gap, it is pushed back and automatically retracts. This process ensures that the filling material is fully filled, avoids unnecessary waste and uneven road surface caused by overfilling, and guarantees the construction quality.

[0038] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] See Figure 1 The three-dimensional representation of the road construction transverse joint treatment device of the present invention is shown. Figure 1 See also Figure 2 The three-dimensional representation of the road construction transverse joint treatment device of the present invention is shown. Figure 2 See also Figure 3 The three-dimensional representation of the road construction transverse joint treatment device of the present invention is shown. Figure 3 .

[0040] Combination Figure 1 , Figure 2 and Figure 3 As shown, the present invention provides a road construction transverse joint treatment device that efficiently and accurately handles common transverse joint problems in road construction, ensuring road surface smoothness and durability, including: a supply unit 21 and a spraying unit 31.

[0041] The supply section 21 is used to hold filling materials, such as asphalt, concrete repair material, or special sealant. These materials are selected according to the road surface material and repair requirements to ensure effective filling and sealing of transverse joints.

[0042] The supply section 21 is a sealed container to prevent the material from becoming damp, hardened, or contaminated during storage. It is equipped with a stirring or heating device to maintain the material's fluidity and viscosity, facilitating subsequent spraying.

[0043] The spraying section 31 includes a spraying pipe 32 that communicates with the supply section 21. A spraying head 33 is fitted onto the end of the spraying pipe 32 away from the supply section 21. A spring 332 is fitted onto the outside of the spraying pipe 32 and the spraying head 33. The two ends of the spring 332 are fixedly connected to the spraying pipe 32 and the spraying head 33, respectively. The spraying pipe 32 ensures that the material can flow smoothly from the supply section 21 to the spraying head 33, and the spraying head 33 accurately sprays the material into the cross joint of the road surface.

[0044] The material in the supply section 21 is precisely and evenly sprayed into the road surface cross joints through the spray head 33.

[0045] When the spray head 33 is supported on the road surface, the extension and retraction of the spring 332 can make the spray head 33 finely adjust its position in the vertical direction, ensuring that the spray head 33 maintains an appropriate distance and angle with the transverse seam, thereby improving the accuracy and efficiency of filling.

[0046] The precise control and telescopic function of the spray head 33 ensures that the filling material can be evenly and accurately filled into the transverse joints, avoiding problems such as unevenness and incomplete filling that may occur with traditional manual filling, thus improving the smoothness and durability of the road surface.

[0047] See Figure 4 The image shows an enlarged view of part A of the road construction transverse joint treatment device of the present invention.

[0048] like Figure 4 As shown, in a preferred embodiment of the road construction transverse joint treatment device of the present invention, the spray head 33 includes: a first connecting sleeve 331 and a moving frame 333.

[0049] The first connecting sleeve 331 is sleeved on the outer side of the injection pipe 32 at the end away from the supply part 21. The first connecting sleeve 331 can slide relative to the injection pipe 32, which not only protects the injection pipe 32, but also provides mechanical support for the extension and retraction of the injection head 33 through relative sliding with the injection pipe 32.

[0050] Spring 332 is sleeved on the outside of first connecting sleeve 331. One end of spring 332 is fixedly connected to first connecting sleeve 331. The presence of spring 332 provides elastic support for spray head 33, so that spray head 33 can have a certain buffer and self-adaptive ability when in contact with road surface, ensuring the stability and accuracy of spraying process.

[0051] The movable frame 333 is sleeved on the outside of the first connecting sleeve 331. The movable frame 333 can move on the road surface. It is not only a support structure for the entire spraying part 31 on the road surface, but also enables the entire device to carry out continuous filling operations along the transverse cracks of the road surface through its mobility.

[0052] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, a second connecting sleeve 33 is provided at the end of the spray pipe 32 away from the supply part 21.

[0053] One end of the spring 332 is connected to the outside of the second connecting sleeve 33, and the first connecting sleeve 331 is slidably disposed on the outside of the second connecting sleeve 33.

[0054] The second connecting sleeve 33 not only provides a stable connection point for the spring 332, but also, through its structural design, allows the first connecting sleeve 331 to slide smoothly on its outer side. This enhances the connection strength and stability between the components of the injection unit 31.

[0055] The first connecting sleeve 331 is slidably mounted on the outside of the second connecting sleeve 33, allowing the spray head 33 to be finely adjusted in the vertical direction. When the spray head 33 contacts the transverse joint of the road surface, the distance and angle between the spray head 33 and the transverse joint can be automatically adjusted by sliding the first connecting sleeve 331 on the second connecting sleeve 33 to adapt to different road conditions and transverse joint depths.

[0056] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, the axial length of the second connecting sleeve 33 is greater than the axial length of the first connecting sleeve 331. This allows the first connecting sleeve 331 to have a longer sliding distance inside the second connecting sleeve 33, thereby increasing the adjustment range of the spray head 33 in the vertical direction. When the spray head 33 contacts the road surface and is subjected to pressure, the first connecting sleeve 331 can slide smoothly over a longer distance to adapt to different road surface heights and transverse joint depths.

[0057] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, the movable frame 333 includes: a connector 334 fixedly sleeved on the outside of the first connecting sleeve 331 and two movable wheels 335 rotatably connected to both sides of the connector 334.

[0058] The connecting member 334 serves as the main body of the movable frame 333. The middle portion of the connecting member 334 is shaped to fit over the outer side of the first connecting sleeve 331, and is fixedly connected to the first connecting sleeve 331 by bolts, welding, or other methods. The connecting member 334 can then move together with the first connecting sleeve 331, transmitting the moving force to the moving wheels 335. The two moving wheels 335 are connected to the connecting member 334 via rotatable connections (such as bearings, bushings, etc.). The design of the moving wheels 335 allows the device to roll easily on the road surface, reducing frictional resistance and improving movement efficiency.

[0059] During construction, when it is necessary to move the device to fill transverse joints at different locations, the operator can do so by pushing or pulling the device. The connecting piece 334, acting as the support and transmission component of the moving frame 333, transmits external force to the moving wheels 335. The moving wheels 335 roll on the road surface, propelling the entire device along a pre-set route. Because the moving wheels 335 and the connecting piece 334 are rotatably connected, the device maintains a relatively stable state during movement, reducing filling quality problems caused by vibration or shaking.

[0060] In another preferred embodiment of the road construction transverse joint treatment device of the present invention, the movable frame 333 includes: a connector 334 slidably sleeved on the outside of the first connecting sleeve 331 and two movable wheels 335 rotatably connected to both sides of the connector 334. The connector 334 is slidably connected to the first connecting sleeve 331, which improves the shock absorption capability of the device.

[0061] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, the movable frame 333 further includes: a brake 336 disposed at the end of the connector 334 and installed adjacent to the movable wheel 335, the brake 336 being used to control the stop of the movable wheel 335.

[0062] During construction, when the device moves to the transverse joint that needs to be filled, the moving wheel 335 is stopped by operating the brake 336 mechanism. Once the brake 336 is activated, the brake pads respond quickly and act on the moving wheel 335, stabilizing the device in a very short time, allowing subsequent filling work to proceed while ensuring the device is accurately positioned. Specifically, a brake lever 36 is provided on the spray pipe 32 for controlling the brake 336.

[0063] In a preferred embodiment of the road construction cross joint treatment device of the present invention, the spray head 33 further includes a cleaning part 34 disposed on the front side of the first connecting sleeve 331, which can clean the road surface.

[0064] The cleaning unit 34 is positioned before the spray head 33 sprays material. This allows the cleaning unit 34 to pre-treat the road surface before the spraying operation, removing impurities, dust, and other unfavorable factors from the cross joints and their surroundings.

[0065] The cleaning unit 34 includes a water spray device, brushes, a vacuum cleaner, or a combination thereof. When the unit is moved to the location of the cross-section that needs filling, the cleaning unit 34 is activated. The water spray device sprays high-pressure water to wash away dust and debris from the surface; the brushes further remove stubborn stains by rotating or vibrating; and the vacuum cleaner collects the washed-away or brushed-off debris, keeping the work area clean.

[0066] The cleaning unit 34 and the spray head 33 work together to form a complete operation process. The cleaning unit 34 pre-treats the road surface to ensure that the transverse joints and their surrounding areas are clean and free of impurities; the spray head 33 then sprays material into the transverse joints to complete the filling operation. This ensures that the material can better penetrate into the transverse joints and form a tight bond with the road surface. This helps to improve the density and durability of the fill and reduce quality problems caused by impurities.

[0067] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, the supply unit 21 includes: a movable base 22 and a storage bin 23 disposed on the base 22.

[0068] The storage bin 23 is connected to the injection pipe 32 to provide filling material for the injection pipe 32.

[0069] The entire supply system can move along with the road construction cross-joint treatment device, maintaining a stable relative position with the spray head 33. The base 22 is made of a robust and durable material to support the weight of the storage bin 23 and its internal materials, and to ensure stability during movement.

[0070] To ensure that during the filling operation, the supply unit 21 can always closely follow the nozzle 33 and provide materials in a timely manner.

[0071] The storage bin 23, mounted on the base 22, is the main container for storing filling materials. It has a certain volume to hold sufficient material for extended operation. The storage bin 23 and the spray head 33 form a complete material supply system. When the spray head 33 requires material, the material in the storage bin 23 is transported to the spray head 33 through pipes and sprayed out through the nozzles to fill the transverse cracks in the road surface.

[0072] To achieve precise control over the material supply, the storage silo 23 may be equipped with devices such as flow control valves and pressure sensors. These devices can monitor the flow rate and pressure of the material and adjust the conveying speed as needed to ensure that the nozzle 33 receives a stable and appropriate supply of material.

[0073] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, the supply unit 21 further includes: a jet pump 24, the input end of the jet pump 24 being connected to the storage bin 23, and the output end of the jet pump 24 being connected to the jet pipe 32.

[0074] When the jet pump 24 starts, it pressurizes the sucked material and sends the pressurized material into the jet pipe 32 through the output end.

[0075] To achieve precise control over the operation of the jet pump 24, the supply unit 21 may also be equipped with a corresponding control device. The control device can monitor the operating status of the jet pump 24 (such as flow rate, pressure, etc.) and adjust the operating parameters of the jet pump 24 (such as speed, power, etc.) as needed to ensure the stability and accuracy of material supply.

[0076] The material conveying efficiency is significantly improved. The jet pump 24 pressurizes the material, increasing the jetting speed and range. This allows the material to fill the road surface cracks more accurately, reducing filling quality problems caused by insufficient or uneven spraying. The pressurization also helps the material penetrate deeper into the cracks, improving the density and durability of the fill.

[0077] See Figure 5 The image shows an enlarged view of part B of the road construction transverse joint treatment device of the present invention.

[0078] like Figure 5 As shown, in a preferred embodiment of the road construction transverse joint treatment device of the present invention, the spray pipe 32 is provided with a handle 35.

[0079] The handle 35 is designed for easy gripping by operators and allows for flexible adjustment of the direction and angle of the spray nozzle 32 as needed. During the treatment of transverse joints in road construction, the spray nozzle 32 is typically held by hand. The addition of a handle 35 allows operators to grip the spray nozzle 32 more easily, reducing hand fatigue, improving work efficiency, and facilitating easy adjustment of the direction and angle of the spray nozzle 32 to ensure accurate spraying of material into the transverse joints. This is particularly important for filling transverse joints of different shapes, sizes, and depths. Specifically, a brake lever 36 is mounted on the handle 35 for convenient control of the brake 336.

[0080] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, a controller 37 is provided on the handle 35. The controller 37 is connected to the jet pump 24 and the cleaning part 34, and controls the start and stop of the jet pump 24 and the cleaning part 34, so as to control the construction status more conveniently.

[0081] In a preferred embodiment of the road construction transverse joint treatment device of the present invention, a storage battery 38 is provided on the spray pipe 32. The storage battery 38 is used to power the entire device, specifically to power the cleaning unit 34, the spray pump 24 and the controller 37, thus expanding the application scenarios of the device.

[0082] The present invention also provides a method for treating transverse joints in road construction, comprising the following steps:

[0083] The operator holds the spray pipe 32 and points the spray head 33 toward the construction transverse joint, applying downward pressure to press the spray head 33 onto the road surface at the construction transverse joint. This not only ensures that the spray head 33 can directly act on the transverse joint, but also creates a certain sealing effect between the spray head 33 and the transverse joint through the top support effect, which helps to accurately inject the filling material.

[0084] The supply unit 21 delivers filling material to the spray head 33. After receiving the material, the spray head 33 sprays it into the transverse slit at a certain pressure and speed.

[0085] When the operator feels the force of the filling material acting on the spray pipe 32 while holding the spray pipe 32, the operator moves the spray pipe 32 forward along the direction of the construction transverse joint to inject the filling material into the next area until the current transverse joint construction is completed.

[0086] When the nozzle 33 stops retracting, it means that the nozzle 33 has been compressed to its limit. Therefore, the height of the transverse seam has reached the design height. The operator can move the nozzle 31 to the next area to be constructed and repeat the above steps to fill it.

[0087] By precisely aligning and supporting the injection head 33, the filler material is ensured to be injected directly and accurately into the transverse crack, avoiding material waste and repeated filling. This facilitates the even distribution and deep penetration of the filler material within the transverse crack. The filled transverse crack not only has a smooth appearance but also high density and durability.

[0088] The present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
