Description

TECHNICAL FIELD

[0001] The present application relates to the field of additive formulations for self-repairing sand-gravel concrete, and more particularly, to an additive formulation for self-repairing sand-gravel concrete and a method of use. BACKGROUND

[0002] Roads are infrastructure for vehicles and pedestrians to pass through. Currently, road pavements are mainly divided into cement concrete pavements and self-repairing sand-gravel concrete pavements. Self-repairing sand-gravel concrete pavements refer to pavement structures formed by mixing asphalt (i.e., petroleum-derived binder) and mineral aggregates (such as gravel, stone chips, etc.). They have the characteristics of strong durability, convenient construction, and low maintenance cost.

[0003] Currently, after the self-repairing sand-gravel concrete pavement is constructed and formed, the pavement needs to be cut for joint treatment, which can control crack propagation and facilitate drainage. The goal of cutting is to cut a number of joints in the pavement along the width direction of the pavement. These joints have both ends penetrating the pavement. When the operator directly operates the pavement cutting machine to complete the cutting operation, the cutting effect is greatly influenced by the operator's technical ability, working state, and other factors, and it is difficult to ensure that the cutting effect meets the expected result. For example, the joints are prone to be skewed and deviate from the predetermined extension direction. In particular, when a large number of joints need to be cut and the operator needs to keep a curved state during the cutting process, the probability of operator's mistake will also increase. SUMMARY

[0004] The present application provides an additive formulation for self-repairing sand-gravel concrete and a method of use to solve the technical problem that the cutting effect cannot be guaranteed to meet the expected result when the operator directly operates the pavement cutting machine to complete the cutting treatment of the self-repairing sand-gravel concrete pavement.

[0013] In this embodiment of the invention, the infusion assembly further includes a separator and a drive structure. The drive structure is connected to the wall of the storage tank and is electrically connected to the controller. The separator is connected to the drive structure and is used to divide the storage tank into a first sub-tank and a second sub-tank.

[0014] In this embodiment of the invention, a covering component is also included, which is installed on the support frame.

[0015] In an embodiment of the invention, the covering component includes a connecting part connected to the support frame and at least one detachable covering part connected to the connecting part. The connecting part and the covering part can be enclosed with the self-healing gravel concrete road surface to form a receiving cavity for accommodating the support frame, the moving component, the cutting component, the limiting component, and the control component.

[0016] In this embodiment of the invention, a first adhesive is connected to the connecting part, and a second adhesive corresponding to the first adhesive is connected to each of the covering parts.

[0017] In this embodiment of the invention, the covering portion is configured as multiple portions; At least one cover has a connecting part, a pushing part, and a water-absorbing part.

Each lateral moving unit includes a vertical output part and a bidirectional rolling element connected to the vertical output part. The vertical output part is mounted on the support frame and electrically connected to the controller. The bidirectional rolling element is used to drive the support frame to move in a direction perpendicular to the first direction.

[0032] like Figure 8 As shown, in this embodiment of the invention, the slit cutting mechanism 33 includes a plurality of telescopic members 331 connected to the connector 32 and a plurality of slit cutting members 332 connected one-to-one with each telescopic member 331. All slit cutting members 332 are electrically connected to the controller 51. The telescopic members 331 are used to adjust the height of the slit cutting members 332.

[0033] like Figure 2 , Figure 7 , Figure 9 As shown, in this embodiment of the invention, an infusion assembly 6 is also included for delivering liquid to at least a portion of the slit assembly 3; The infusion assembly 6 includes a reservoir 61, a cover 62, and an electric control unit 63.

[0034] like Figure 10 As shown, in this embodiment of the invention, the infusion assembly 6 further includes a separator 64 and a drive structure 65. The drive structure 65 is connected to the wall of the storage tank 611 and is electrically connected to the controller 51. The separator 64 is connected to the drive structure 65 and is used to divide the storage tank 611 into a first sub-tank and a second sub-tank.

[0035] like Figure 3 , Figure 12 As shown, in this embodiment of the invention, a covering component 7 is also included, which is installed on the support frame 1. The covering component 7 can be enclosed with the self-healing sand and gravel concrete road surface to form a receiving cavity for accommodating the support frame 1, the moving component 2, the cutting component 3, the limiting component 4, and the control component 5.

[0036] like Figure 12 As shown, in this embodiment of the invention, the covering component 7 includes a connecting part 71 connected to the support frame 1 and at least one covering part 72 detachably connected to the connecting part 71. The connecting part 71 and the covering part 72 can be enclosed with the self-healing gravel concrete road surface to form a receiving cavity for accommodating the support frame 1, the moving component 2, the cutting component 3, the limiting component 4, and the control component 5.

[0037] like Figure 12 As shown, in this embodiment of the invention, a first adhesive member 8 is connected to the connecting part 71, and a second adhesive member 9 corresponding to the first adhesive member 8 is connected to both the covering part 72.

[0038] like Figure 13 As shown, in this embodiment of the invention, the covering portion 72 is configured as a plurality of portions; At least one cover 72 has a connecting part 721, a pushing part 722, and a water-absorbing part 723. The connecting part 721 is detachably connected to the connecting part 71. The pushing part 722 and the water-absorbing part 723 are both detachably connected to the connecting part 721. The pushing part 722 is used to push debris on the self-healing gravel concrete road after the receiving cavity is formed. The water-absorbing part 723 is used to absorb liquid on the self-healing gravel concrete road after the receiving cavity is formed.

[0039] In this embodiment of the invention, a third adhesive member 13 and a fourth adhesive member 14 are connected to the connecting sub-component 721; Along the extension direction of the pusher component 722, the thickness of both the pusher component 722 and the absorbent component 723 gradually decreases; Both the push component 722 and the absorbent component 723 are elastic.

[0040] like Figure 2 , Figure 4 , Figure 6 As shown, in this embodiment of the invention, at least one lateral moving unit 10 is also included. Each lateral moving unit 10 includes a vertical output part 101 and a bidirectional rolling element 102 connected to the vertical output part 101. The vertical output part 101 is installed on the support frame 1 and is electrically connected to the controller 51. The bidirectional rolling element 102 is used to drive the support frame 1 to move in a direction perpendicular to the first direction.

[0041] like Figure 11 As shown, in this embodiment of the invention, the support frame 1 has an inner cavity 11, and the support frame 1 is provided with a plurality of observation ports 12 communicating with the inner cavity 11.

[0042] The working process of this invention is as follows: The construction device is responsible for cutting joints in self-healing gravel concrete roads. Its main support structure is the support frame 1, and the moving component 2 drives the support frame 1 and other structures to move. The cutting component 3 is the actual cutting structure that performs the cutting process. During the cutting process, the moving component 2 is restricted in its direction of movement by the limiting component 4, and the drive structure 65 in each component is controlled by the control component 5, specifically by the controller 51. For example, the controller 51 controls the operation and stop of the cutting component 3. In some cases, when using the construction device, the operator moves the device to a predetermined position and then pushes it to move; that is, the operator supplies driving force to the device so that the moving component 2 drives the support frame 1 and other structures to move. The controller 51 controls the operation of each component, and the operator can control the controller 51 in ways including but not limited to voice control and button pressing.

[0043] When an operator directly manipulates the cutting assembly 3 to complete the cutting process, the cutting effect is greatly affected by factors such as the operator's technical ability and working condition, making it impossible to guarantee that the cutting effect will meet expectations. For example, the road joint is prone to skew and deviate from the predetermined extension direction, especially when there are many road joints to be cut, the probability of operator error also increases. Compared with the method of the operator directly manipulating the cutting assembly 3 to complete the cutting process, in this invention, the operator is mainly responsible for pushing the support frame 1 to move the entire construction device, and secondly responsible for controlling the operation and stopping of the cutting assembly 3 and other structures through the controller 51. By setting the limiting component 4, the movement direction of the moving component 2 is restricted. During the cutting process, it can be restricted to move bidirectionally along the predetermined extension direction of the road joint, thereby preventing the road joint from deviating from the predetermined extension direction. In this invention, during the actual slit cutting process, the operator is kept at a certain distance from the slit cutting assembly 3. Therefore, the impact of dust and gravel generated by the slit cutting assembly 3 on the operator is reduced. For example, the amount of dust dissipates more before contacting the operator, and the total amount of gravel that can contact the operator is reduced. In addition, in this invention, the operator's back does not need to be kept bent for several time periods during the entire slit cutting process, thereby reducing the negative impact of the slit cutting process on the operator's body.

[0044] During the cutting process, the moving component 2 drives the cutting component 3 to move. The rotating part 211 and the bidirectional rolling part 212 are the smallest constituent units of the moving component 2. When the rotating part 211 is fixed relative to the support frame 1, the bidirectional rolling part 212 can only move bidirectionally in two symmetrically distributed directions. Only when the rotating part 211 moves relative to the support frame 1 does the movable direction of the bidirectional rolling part 212 change. The bidirectional rolling part 212 can adopt various structures, such as the roller structure on a skateboard, as long as it has bidirectional movement function, no specific limitation is made here.

[0045] Before the slit is cut, the limiting component 4 restricts the movable direction of the moving component 2. In some cases, the drive unit 411 within the limiting component 4 is configured as a combination of a motor, a connecting rod, and a connecting wire. The connecting rod is mounted on the support frame 1 and has an arc-shaped structure. The motor is connected to the support frame 1 or the connecting rod and is electrically connected to the controller 51. The limiting part 412 is slidably connected to the connecting rod and connected to the connecting wire. Initially, part of the connecting wire is wound around the outside of the motor output end, and the limiting part 412 is away from the two adjacent corresponding bidirectional rolling parts 212. During the limiting stage, the motor unwinds the connecting wire, and the limiting part 412 slides between the two bidirectional rolling parts 212 belonging to the same group of moving mechanisms 21 under the action of gravity. The limiting part 412 is the actual limiting structure. When the limiting part 412 moves between the corresponding two bidirectional rolling parts 212, the rotating part 211 cannot drive the bidirectional rolling part 212 to rotate around the axis of the rotating part 211, thereby locking the moving direction of the bidirectional rolling part 212. Before the limiting part 412 moves between the corresponding two bidirectional rolling parts 212, the operator can separate the corresponding bidirectional rolling parts 212 from the road surface to avoid the bidirectional rolling parts 212 obstructing the movement of the limiting part 412. The reset part 413 can be configured as a spring structure. After the bidirectional rolling parts 212 are separated from the self-healing gravel concrete road, the reset part 413 can pull the corresponding rotating part 211 to reset, so that the structure that may obstruct the limiting part 412 loses its function of obstructing it before the limiting part 412 moves to the predetermined position.

[0046] In the cutting assembly 3, the drive component 31 can be an electric cylinder. The drive component 31 can adjust the height of the cutting mechanism 33 via the connecting component 32. The cutting component 332 can be an electric cutter, and the telescopic component 331 can be an electric telescopic rod. By setting multiple cutting components 332 and multiple telescopic components 331, the height of each cutting component 332 can be different by adjusting its own length. Thus, each cutting component 332 can cooperate to cut different depths of the road, reducing the difficulty of cutting and the probability of the cutting progress being affected by damage to the cutting component 332 during long-term cutting.

[0047] During the cutting process, the liquid storage component can supply cooling water to the cutting component 3, which can extend the service life of the cutting component 3 by reducing its temperature during cutting. It can also form a lubricating layer between the cutting component 3 and the road surface to reduce friction during cutting. Furthermore, it can clean the cutting component 3, completing at least part of its maintenance. The liquid storage component can also supply water to the road surface, thereby reducing the amount and range of dust emission, making it easier for operators to observe the cutting condition. Simultaneously, it can lower the road surface temperature, potentially aiding in the cutting of self-healing aggregate concrete. Considering that high temperatures can soften self-healing aggregate concrete, making cutting more difficult and affecting the quality, lowering the road surface temperature can improve cutting efficiency and quality in hot seasons or areas with high temperatures. The liquid storage component can also partially cover the cutting component 3 to limit the dispersion of gravel generated during road cutting, reducing subsequent cleanup difficulty and preventing injury to operators from flying gravel. The liquid storage component can also precisely spray water onto the cutting component 3 and the road surface near the cutting component 3, thereby reducing water consumption while ensuring the above-mentioned effects. Excessive water consumption may affect subsequent construction processes, such as reducing the adhesion of paint or adhesives. Therefore, this design reduces the difficulty of subsequent water removal. Optionally, the electric control component 63 includes an electric control valve and a water outlet pipe. The water outlet pipe is installed at the opening of the liquid outlet 612, and the electric control valve is installed on the water outlet pipe. The electric control valve is electrically connected to the controller 51.

[0048] The storage tank 611 is used to store water. Through the partition 64, the storage tank 611 is divided into a first sub-tank and a second sub-tank, and the sizes of the first and second sub-tanks can change as the partition 64 moves. The first and second sub-tanks can be used to store water and lubricating oil, respectively. Taking water in the first sub-tank and lubricating oil in the second sub-tank as an example, initially, the outlets 612 are all connected to the first sub-tank. When lubricating oil is needed, the drive structure 65 drives the partition 64 to move, so that the outlets 612 are all connected to the second sub-tank. At this point, the lubricating oil replaces the water in contact with the cutting assembly 3. Optionally, the drive structure 65 is configured as a single-axis robot.

[0049] Covering component 7 is used selectively during the cutting process. When in use, covering component 7 can be enclosed with the self-healing aggregate concrete road surface to form a cavity for accommodating support frame 1, moving component 2, cutting component 3, restraining component 4, and control component 5, thereby protecting the cutting component 3 and other structures. Covering component 7 is especially suitable for use in rainy weather and can prevent water ingress and damage to the cutting component 3 and other structures.

[0050] After the cover assembly 7 is put into use, it can completely limit the range of dust emission and gravel dispersion during the cutting process, avoiding negative impacts on the operator's health caused by dust and gravel. The use of the cover assembly 7 can affect the propagation of noise, thereby reducing the impact of noise generated by the cutting assembly 3 on surrounding personnel and improving the operator's working environment. The arrangement of the first adhesive member 8 and the second adhesive member 9 facilitates the fixation of the cover 72 when it is not in use, preventing the cover 72 from changing from a retracted state to an unfolded state during the movement of the support frame 1.

[0051] The multiple covering sections 72 make the use of the covering assembly 7 more versatile. For example, the distribution range of gravel can be limited in a specific direction according to usage needs. At the same time, when the covering assembly 7 is partially damaged, the entire covering assembly 7 can be avoided. For the covering section 72, which includes a connecting part 721, a pushing part 722, and a water-absorbing part 723, the connecting part 721 is used to connect with the connecting part 71. The specific connection method includes, but is not limited to, adhesive bonding. When in use, at least part of the pushing part 722 is in contact with the ground, thereby pushing the gravel to move, so as to eliminate the subsequent gravel cleaning steps or reduce the difficulty of subsequent gravel cleaning. The water-absorbing part 723 can be made of materials such as super absorbent resin. When it moves with the pushing part 722, it can absorb the water that leaves the infusion assembly 6 and falls to the ground, avoiding the possibility that the subsequent construction process may be affected by the accumulation of too much water on the ground. The third adhesive component 13 and the fourth adhesive component 14 can be made of materials such as Velcro or adhesive soft board. When the third adhesive component 13 and the fourth adhesive component 14 are bonded together, the end of the pusher component 722 with the lower thickness can be kept perpendicular to the road surface. Then, after the end of the pusher component 722 with the lower thickness is inserted into the road crack, the pusher component 722 can clean the debris in the road crack, and the water-absorbing component 723 can absorb the water in the road crack. It should also be noted that both the pusher component 722 and the water-absorbing component 723 are elastic, and the thickness of each part of the pusher component 722 and the thickness of each part of the water-absorbing component 723 are different. This can achieve the purpose of the pusher component 722 filling the road crack and the purpose of the part of the pusher component 722 outside the road crack to move the debris accumulated on both sides of the top of the road crack, thereby preventing these debris from easily falling back into the road crack after the pusher component 722 is removed. The structure of the bidirectional rolling element 102 can, in some cases, be considered as a combination of the rotating part 211 and the bidirectional rolling part 212. When viewed this way, the rotating part 211, belonging to the bidirectional rolling element 102, cannot rotate relative to the vertical output part 101 around its own axis. The bidirectional rolling element 102 is used to move the support frame 1 in a direction perpendicular to the first direction. Thus, the lateral movement unit 10 can replace the moving component 2 to move the support frame 1 and other structures for a certain period of time, avoiding the need to repeat all the above operations after a single road joint is cut, especially the need to readjust the movable direction of the bidirectional rolling part 212 after moving the support frame 1 to the next predetermined position. During the process of the lateral movement unit 10 replacing the moving component 2, the operator can repeatedly perform the operation of separating the bidirectional rolling part 212 from the road surface. When one end of the support frame 1 separates from the ground, the vertical output part 101 drives the bidirectional rolling element 102 closer to the road surface, and then the operator lifts the other end of the support frame 1. At this time, the lateral movement unit 10 replaces the moving component 2 in contact with the road surface. In some cases, the vertical output part 101 can be directly activated, omitting the other operations mentioned above. Example

[0052] On the other hand, embodiments of the present invention also provide a method for using self-healing aggregate concrete, including the following steps: Move support frame 1 to the predetermined position; Activate controller 51 to restrict the operation of component 4 in order to limit the movement direction of moving component 2; The cutting assembly 3 operates to cut the road surface; The moving component 2 moves under the influence of an external force.

[0053] The construction device is responsible for cutting joints in the self-healing gravel concrete road. Its main support structure is the support frame 1, and the moving component 2 plays the role of driving the support frame 1 and other structures to move. The cutting component 3 is the cutting structure that actually performs the cutting process. During the cutting process, the moving component 2 is restricted by the limiting component 4, and the driving structure 65 in each component is controlled by the control component 5. Specifically, it is controlled by the controller 51. For example, the controller 51 controls the operation and stop of the cutting component 3.

[0054] In some cases, when using the construction device, the operator moves the construction device to a predetermined position, and then the operator pushes the construction device to move it. That is, the operator sends driving force to the construction device so that the moving component 2 drives the support frame 1 and the rest of the structure to move.

[0055] The embodiments of this example have been described above. However, this example is not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this example, and all of them are within the protection scope of this example.
