Description

TECHNICAL FIELD

[0001] The application relates to the technical field of semi-rigid base reflective crack and cement concrete pavement overlay crack treatment, in particular to a pavement anti-cracking patch on-site processing and laying device. BACKGROUND

[0002] Highways mainly adopt the structure of cement stabilized semi-rigid base asphalt, and the reflective crack of the cement stabilized semi-rigid base is a stubborn problem of the asphalt pavement. At the same time, the reflective crack treatment is the primary problem to be solved in the "black" overlay pavement engineering of the cement concrete pavement. So far, the polymer modified asphalt anti-cracking patch material, that is, the roll-shaped material with self-adhesion, waterproof and anti-cracking effects, which is composed of the surface reinforcing layer of the engineering fiber woven fabric, the upper and lower impregnated coating of the polymer modified asphalt colloid and the bottom isolation film of the polyester film, is an important technical approach to prevent, treat and inhibit the delay of the reflective crack.

[0003] The traffic and transportation industry standard "Polymer Modified Asphalt Anti-Cracking Patch for Asphalt Overlay" JT / T 971 stipulates that the anti-cracking patch is divided into two types of hot-adhesion type anti-cracking patch and self-adhesion type anti-cracking patch according to the construction mode, and the specifications are as follows: the thickness is 2 mm or 3 mm, and the width is 24 cm, 32 cm or 48 cm, and the width and the length per roll can be customized according to the requirements. For a long time, the anti-cracking patch mainly adopts the operation mode of factory production, packaging transportation and manual film tearing and laying on site. Due to the influence of the natural climate environment in different regions, the surface temperature of the lower bearing layer (semi-rigid base or cement concrete), the properties of the traditional anti-cracking patch material and the like, the traditional anti-cracking patch often faces the following problems in the step-by-step construction: 1. The anti-cracking patch is frequently loaded and unloaded and transported, and is prone to extrusion deformation and adhesion problems; 2. In order to enhance the interlayer adhesion of the pavement, the lower bearing layer is usually treated by milling and roughening to form a concave-convex texture structure. Since the equal-thickness polymer modified asphalt colloid produced by the traditional factory cannot effectively fill the gaps of the existing reflective cracks, on the one hand, the colloid cannot be fully compacted with the lower bearing layer, and on the other hand, the engineering fiber woven fabric cannot be fully spread, which reduces the water sealing and tensile capacity of the anti-cracking patch colloid and the fiber woven fabric to different degrees; secondly, the dynamic adaptability of the equal-thickness colloid to different structures of the lower bearing layer is poor, and when too much colloid adhesion is not needed, the pavement is prone to strip oil bleeding after the hot-mixed asphalt mixture is overlaid; 3. When the environmental temperature or the surface temperature is slightly low, the anti-cracking patch is usually laid by using open flame, which is easy to cause colloid high-temperature aging and fiber woven fabric structure damage; 4. Since the colloid of the anti-cracking patch is in a constant temperature solid state, when the dust of the lower bearing layer cannot be completely cleaned, the anti-cracking patch and the lower bearing layer are prone to isolation, and after the construction vehicle is rolled, the failure and damage such as rolling up and tearing off often occur; 5. The anti-cracking patch is mainly laid by manual operation, and when a large area is operated, a rubber-tired road roller is usually needed to be equipped to promote adhesion, which is low in work efficiency and high in indirect cost.

[0034] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0035] In the present disclosure, the orientation words such as "up, down" used herein generally refer to the "up, down" of the corresponding components in the use state in the direction of gravity, and "inner, outer" refers to the "inner, outer" relative to the outline of the corresponding component itself. In addition, the terms "first", "second", etc. used in the present disclosure are used to distinguish one element from another element, and do not have sequentiality and importance. In the following description, when referring to the drawings, the same reference signs in different drawings represent the same or similar elements, unless otherwise explained.

[0036] Reference Figures 1 to 7 , a road anti-cracking patch on-site processing and laying device, comprising:

[0037] The main vehicle frame 1, the auxiliary vehicle frame 2, the colloidal spraying assembly 3, the colloidal stirring and feeding device 4, the woven cloth laying assembly 5, and the pumping assembly 6.

[0038] The auxiliary vehicle frame 2 can be connected to the front or side of the main vehicle frame 1. In actual construction sites, the direction of the reflective cracks is random, which can be parallel to the pavement extension direction, perpendicular to the pavement extension direction, or inclined to the pavement extension direction. When the reflective cracks are parallel to the pavement extension direction, the auxiliary vehicle frame 2 can be arranged in front of or on the side of the main vehicle frame 1. When the cracks are perpendicular to the pavement extension direction, the width of the pavement is usually limited (especially for single-lane or local reflective crack treatment), and the main vehicle frame 1 itself occupies a certain length and turning radius. If the auxiliary vehicle frame 2 is arranged in front of the main vehicle frame 1, the space occupied by the main vehicle frame 1 itself makes it impossible to lay the pavement reflective cracks in the starting section. Therefore, when the reflective cracks are perpendicular to the pavement extension direction, it is not convenient to arrange the auxiliary vehicle frame 2 in front of the main vehicle frame 1 for construction. Therefore, connecting the auxiliary vehicle frame 2 to the side of the main vehicle frame 1 can treat pavement reflective cracks in any direction.

[0039] Reference Figure 1 The auxiliary vehicle frame 2 is connected to the side of the main vehicle frame 1 as an example.

[0040] The colloidal spraying assembly 3 is arranged in front of the auxiliary vehicle frame 2 in the direction of travel, and is used to spray colloidal to the pavement reflective crack area to be treated. Reference Figure 1 and Figure 2 The colloidal stirring and feeding device 4 is arranged on the main vehicle frame 1 and has a colloidal outlet 401. The colloidal stirring and feeding device 4 is used to provide a crack-resistant adhesive and sealing waterproof colloidal. The woven cloth laying assembly 5 is arranged on the auxiliary vehicle frame 2 and is located behind the colloidal spraying assembly 3, and is used to lay woven cloth to the pavement reflective crack area after spraying colloidal. The pumping assembly 6 includes a colloidal pump 601, a first colloidal conveying pipe 602 connected between the colloidal pump 601 inlet and the colloidal outlet 401, and a second colloidal conveying pipe 603 connected between the colloidal pump 601 outlet and the colloidal spraying assembly 3. The pumping assembly 6 is used to pump the colloidal provided by the colloidal stirring and feeding device 4 to the colloidal spraying assembly 3.

[0041] In the above embodiment, the colloidal agitating and feeding device 4 is arranged on the main frame 1 and the sub-frame 2, the colloidal spraying assembly 3 is arranged at the front of the sub-frame 2, and the woven cloth laying assembly 5 is arranged at the rear of the sub-frame 2. The colloidal agitating and feeding device 4 is connected to the colloidal spraying assembly 3 through the pumping assembly. When the reflective crack of the road surface needs to be treated, the colloidal agitating and feeding device 4 is started to provide colloidal, and after the colloidal is prepared, the sub-frame 2 is adjusted to be parallel to the reflective crack, and the reflective crack is located in the middle of the woven cloth laying assembly 5. The colloidal spraying assembly 3 is started to spray colloidal to the reflective crack area of the road surface, and then the woven cloth laying assembly 5 lays the woven cloth on the reflective crack area of the road surface which has just been sprayed with colloidal, to form the anti-cracking patch.

[0042] The colloidal for the anti-cracking patch can be a polymer modified asphalt colloidal. The woven cloth can be an engineering fiber woven cloth. The reflective crack of the road surface treated by the in-situ processing and laying device of the road anti-cracking patch can be processed and laid in-situ by the hot-melt or room-temperature liquid polymer modified asphalt colloidal and the impregnated and fused engineering fiber woven cloth, and the crack sealing, waterproofing, interface bonding and the like of the semi-rigid base reflective crack or the construction joint, expansion joint and crack of the cement concrete pavement can be completed in-situ at one time, so that the traditional anti-cracking patch construction process is avoided, the construction process, turnover link and construction defects are avoided, the sealing, waterproofing, bonding and anti-cracking effects of the anti-cracking patch are fully played, and the construction efficiency and construction quality of the anti-cracking patch are improved.

[0043] The polymer modified asphalt colloidal for the anti-cracking patch can be a road heating type sealing glue, and can be a high-temperature type suitable for a minimum air temperature not lower than 0℃, a normal type not lower than -10℃, a low-temperature type not lower than -20℃, a cold type not lower than -30℃, and a severe cold type not lower than -40℃. The polymer modified asphalt colloidal can also be a room-temperature liquid polymer modified asphalt colloidal such as a high-solid-content high-viscosity modified emulsified asphalt, an epoxy modified emulsified asphalt, and a polyurethane cold pouring joint glue.

[0044] According to the embodiment of the present application, referring to Figure 3 The colloidal spraying assembly 3 can include a nozzle fixing rod 301 connected with the sub-frame 2, and a plurality of colloidal nozzles 302 connected with the nozzle fixing rod 301. Each of the colloidal nozzles 302 is in communication with the second glue conveying pipe 603 through a third glue conveying pipe 303, and the plurality of colloidal nozzles 302 are arranged horizontally perpendicular to the traveling direction of the sub-frame 2. In this way, the colloidal can be sprayed more uniformly through the plurality of colloidal nozzles 302. According to the embodiment of the present application, referring to Figure 3In some embodiments, the spray head fixing rod 301 is in sliding connection with the sub-frame 2, and a first lifting oil cylinder 304 can be further arranged between the spray head fixing rod 301 and the sub-frame 2. Thus, the height of the spray head fixing rod 301 can also be adjusted, and the user can adjust the thickness of the gel spraying by adjusting the height of the spray head fixing rod 301 in combination with the pumping speed of the 601 pump.

[0045] According to the embodiments of the present application, referring to Figure 4 , the woven fabric laying assembly 5 comprises a woven fabric roll 501, a U-shaped tensioning rod 502, and a scraper 503.

[0046] The woven fabric roll 501 comprises a rotating shaft and a woven fabric wound on the rotating shaft, the woven fabric roll 501 is in rotating connection with the sub-frame 2, the rotating shaft is perpendicular to the traveling direction of the sub-frame 2, and the woven fabric has a free end; the woven fabric for the anti-cracking paste is an engineering fiber woven fabric, and the roll-shaped fiber woven fabric can be selected in different materials (glass fiber cloth, polyester fiber cloth, anti-cracking base cloth, etc.), different tensions (25KN-100KN), and different widths (20cm-50cm, such as 20cm, 24cm, 32cm, 48cm, etc.).

[0047] The U-shaped tensioning rod 502 has two first arm rods 5021 and a first bottom rod 5022 connecting the two first arm rods 5021, and the tensioning rod is hinged on the sub-frame 2 through the two first arm rods 5021. When the free end of the woven fabric is pasted on the road surface reflection crack area, the first bottom rod 5022 abuts against the side of the woven fabric away from the road surface reflection crack area. The scraper 503 is connected to the two first arm rods 5021 through two connecting rods, and the lower end of the scraper 503 is close to the road surface reflection crack. The scraper 503 is used to apply pressure to the woven fabric towards the road surface.

[0048] In the above embodiments, when the sub-frame 2 travels with the main frame 1 and treats the reflection crack, the colloid spraying assembly 3 located at the front part of the sub-frame 2 first sprays the colloid, the free end of the woven fabric is manually pasted on the starting section of the reflection crack, the main frame 1 travels, and the sub-frame 2 travels with the main frame 1. Under the action of the U-shaped tensioning rod 502 and the scraper 503, the woven fabric can be reliably pasted on the road surface reflection crack, wherein the U-shaped tensioning rod 502 can keep the woven fabric in a tensioned state to prevent the woven fabric from being wrinkled due to redundancy when pasted on the road surface, and the scraper 503 can smooth the woven fabric and make the woven fabric more tightly pasted on the road surface reflection crack area.

[0049] According to the embodiments of the present application, referring to Figure 5The first bottom rod 5022 is slidably connected with a first sliding block 504, and the first sliding block 504 is connected with a cutting knife 505. The first sliding block 504 is slid along the first bottom rod 5022, and the cutting knife 505 can cut the woven fabric between the woven fabric roll 501 and the road surface. In this way, when the treatment of a section of the reflective crack on the road surface is completed, the woven fabric can be cut off by sliding the first sliding block 504 to drive the cutting knife 505.

[0050] According to the embodiment of the present application, referring to Figure 5 The woven fabric laying assembly 5 further comprises a U-shaped resistance rod 506, which comprises two second arm rods 5061 and a second bottom rod 5062 connecting the two second arm rods 5061. The U-shaped resistance rod 506 is hinged on the auxiliary frame 2 through the two second arm rods 5061, and a tension spring 507 is arranged between each second arm rod 5061 and the auxiliary frame 2, so that the second bottom rod 5062 abuts against the outer surface of the woven fabric roll 501. By arranging the resistance rod, the woven fabric roll 501 can be prevented from rotating too fast and causing the woven fabric to collapse and accumulate.

[0051] According to the embodiment of the present application, referring to Figure 5 and Figure 6 The side of the main frame 1 facing the auxiliary frame 2 is provided with two vertical lifting slide rods 101, each of which is provided with a first sliding groove, and a second sliding block 102 is arranged in the first sliding groove. A horizontal translation main slide rod 103 is connected to the two second sliding blocks 102, and a second lifting oil cylinder 104 for driving the translation main slide rod 103 to lift is arranged between the translation main slide rod 103 and the main frame 1. The side of the translation main slide rod 103 facing the auxiliary frame 2 is provided with a second sliding groove, and two third sliding blocks 105 are arranged in the second sliding groove. The auxiliary frame 2 is slidably connected with the main frame 1 through the two third sliding blocks 105. The translation main slide rod 103 is further provided with two slide rail clamping devices 106 for fixing the positions of the third sliding blocks 105.

[0052] In this way, on the one hand, the auxiliary frame 2 can be lifted in the vertical direction due to the arrangement of the lifting slide rod 101, the second sliding block 102 and the second lifting oil cylinder 104 on the main frame 1. This can make the road anti-crack patch on-site processing and laying device more convenient to adjust. For example, when the road anti-crack patch on-site processing and laying device is treating the reflective crack on the road surface, the auxiliary frame 2 can be adjusted to a lowered state, and when no construction work is needed, the auxiliary frame 2 can be adjusted to a raised state to facilitate the rapid movement of the road anti-crack patch on-site processing and laying device.

[0053] On the other hand, since the main frame 1 is further provided with the translation main slide rod 103 and the third slide block 105, the auxiliary frame 2 can move in the horizontal direction along the translation main slide rod 103, that is, in the direction of travel of the main frame 1, so that the road anti-cracking patch in-place processing and paving device can treat the reflection cracks perpendicular to the extension direction of the road surface. Specifically, when the reflection cracks are perpendicular to the extension direction of the road surface, the main frame 1 and the auxiliary frame 2 are first adjusted to be parallel to the reflection cracks and the main frame 1 is fixed, and the auxiliary frame 2 is slid relative to the main frame 1 by pushing the auxiliary frame 2 by hand to treat the reflection cracks perpendicular to the extension direction of the road surface. However, in this case, since the auxiliary frame 2 itself occupies a certain length, the end of the translation main slide rod 103 cannot be paved in place, and can only be manually operated, thereby increasing the labor of the workers. In order to solve this problem, referring to Figure 5 and Figure 6 , the main frame 1 further comprises two translation auxiliary slide rods 107, and the two translation auxiliary slide rods 107 are respectively provided with third slide grooves, and the two translation auxiliary slide rods 107 are foldably connected to the two ends of the translation main slide rod 103; when the translation auxiliary slide rod 107 is unfolded, the third slide groove is in the same horizontal plane as the second slide groove. In this way, by adding foldable translation auxiliary slide rods 107 to the two ends of the translation main slide rod 103, the auxiliary frame 2 can be first slid onto the translation auxiliary slide rod 107 at one end of the translation auxiliary slide rod 107 at the beginning of the construction operation, and the auxiliary frame 2 can be slid onto the translation auxiliary slide rod 107 at the other end of the translation auxiliary slide rod 107 at the end of the construction operation, thereby extending the translation range of the auxiliary frame 2, and further ensuring that there is no dead angle in the construction site, and realizing full coverage of the anti-cracking patch on the reflection cracks.

[0054] According to the embodiments of the present application, referring to Figure 5 , the auxiliary frame 2 can further comprise a telescopic connecting rod 201 and a universal support wheel 202, and the bottom of the auxiliary frame 2 is connected to the universal support wheel 202 through the telescopic connecting rod 201. By providing the telescopic connecting rod 201, the universal support wheel 202 can be further adjusted so that the universal support wheel 202 can support the auxiliary frame 2, thereby keeping the auxiliary frame 2 horizontal.

[0055] According to the embodiments of the present application, referring to Figure 7 , the main frame 1 has a walking wheel 108 and a direction wheel 109; the number of the walking wheel 108 is two, which is located in front of the bottom of the main frame 1, and the number of the direction wheel 109 is two, which is located at the back of the bottom of the main frame 1. The main frame 1 is further provided with a steering wheel for driving the direction wheel 109 to swing.

[0056] According to the embodiments of the present application, referring to Figure 2The colloidal stirring feeding device 4 comprises a heating tank 402 and a stirring assembly 403; the heating tank 402 comprises a tank body and a tank cover; the stirring assembly 403 comprises a stirring motor arranged on the tank cover and a stirrer connected to an output shaft of the stirring motor, the stirrer extending into the tank body; a temperature sensor for measuring the temperature of the colloidal in the heating tank 402 can also be arranged on the heating tank 402; the bottom of the tank body is provided with the colloidal outlet 401.

[0057] The implementation principle of the in-situ processing and laying device for the road anti-cracking patch is described below according to specific operation steps:

[0058] Step 1: Prepare the polymer modified asphalt colloidal and the woven cloth roll 501 in advance, adjust the in-situ processing and laying device for the road anti-cracking patch to the parallel direction of the reflection crack, place the woven cloth laying assembly 5 at the opposite center position of the reflection crack according to the on-site laying width, and adjust the starting position of the woven cloth laying assembly 5 to keep consistent with the end of the reflection crack.

[0059] Step 2: Set the colloidal heating temperature, laying speed, pumping speed, etc., after the colloidal reaches the set temperature, start the stirring assembly 403 and the pumping assembly 6, and debug the colloidal spraying parameters (spraying height, spraying width, spraying thickness).

[0060] Step 3: Place the selected width of the woven cloth under the scraper 503, adjust the height of the U-shaped tension rod 502 to make the woven cloth tightly adhere to the road surface.

[0061] Step 4: Start the colloidal spray head 302, advance according to the set speed, and simultaneously spray the colloidal and lay the woven cloth, and after reaching the laying length of the reflection crack, automatically cut the woven cloth, that is, complete one operation.

[0062] Step 5: Repeat the operation according to the above steps according to the distribution of the reflection crack.

[0063] Compared with the prior art, the technical scheme of the in-situ processing and laying device for the road anti-cracking patch has the following technical advantages:

[0064] 1. The in-situ processing and laying device for the road anti-cracking patch adopts a synchronous operation mode, and the hot-melt or normal-temperature liquid polymer modified asphalt colloidal and the engineering fiber woven cloth are processed and laid in-situ, and the cracks of the reflection crack of the semi-rigid base layer or the construction joint, expansion joint and crack of the cement concrete pavement are sealed and waterproofed, and the interface is bonded, which is completed at one time, avoids the complicated procedures, turnover links and construction defects of the traditional anti-cracking patch, fully plays the sealing, waterproofing, bonding and anti-cracking effects of the anti-cracking patch, and improves the construction efficiency and construction quality of the anti-cracking patch.

[0065] 2、According to the natural climate conditions of different areas and the damage degree of reflective cracks, the specifications of polymer modified asphalt colloid and engineering fiber woven cloth can be dynamically selected. Among them, the polymer modified asphalt colloid used for anti-cracking paste gives priority to road heating type sealant, which can be selected for high temperature type suitable for minimum temperature not lower than 0℃, ordinary type not lower than -10℃, low temperature type not lower than -20℃, cold type not lower than -30℃ and severe cold type not lower than -40℃, and can also be used for high solid content high viscosity modified emulsified asphalt, epoxy modified emulsified asphalt, polyurethane cold pouring seam glue and other normal temperature liquid polymer modified asphalt colloid; the engineering fiber woven cloth used for anti-cracking paste can select roll-shaped fiber woven cloth with different materials (glass fiber cloth, polyester fiber cloth, anti-cracking base cloth, etc.), different tensile forces (25KN-100KN) and different widths (20cm-50cm, such as 20cm, 24cm, 32cm, 48cm, etc.); present processing, not only ensures the quality of anti-cracking paste raw materials from the source, but also improves the adaptability and construction flexibility of anti-cracking paste under different working conditions.

[0066] 3、According to the pump speed of the pump, the colloid nozzle, the lifting device and the width of the woven cloth, the laying speed, and according to the width of the reflective crack gap and the surface texture structure depth of the original pavement, the spraying width and thickness of the hot melt polymer modified asphalt colloid can be dynamically adjusted; during the spraying process of the hot melt colloid, not only the filling and sealing effect of the reflective crack gap is realized, but also the immersion and fusion process of the colloid and the fiber woven cloth is completed at the same time; at the same time, the colloid after spraying is in a high temperature state, and the scraping and compaction extrusion effect of the fiber woven cloth rubber scraper makes the colloid and the fiber woven cloth tightly bond with the existing pavement, effectively ensuring the laying flatness and compactness of the anti-cracking paste and improving the comprehensive anti-cracking and waterproof effect of the anti-cracking paste.

[0067] 4、During construction, the equipment is adjusted to the parallel direction of the reflective crack, the longitudinal center of the fiber woven cloth with different widths, the colloid spraying center and the center position of the reflective crack are kept relatively consistent, which effectively ensures the uniformity of the stress of the anti-cracking paste on both sides of the reflective crack gap and improves the overall tensile and anti-cracking effect of the woven cloth.

[0068] 5、The woven cloth laying assembly and the main frame can be lifted up and down and can also slide horizontally, which ensures that there is no dead angle in the on-site construction of the laying assembly and realizes the full coverage laying operation of the anti-cracking paste on the reflective crack.

[0069] 6、The synchronous and efficient construction operation mode can effectively save construction cost, reduce material waste and improve the treatment effect and use durability of the reflective crack.
