Description

Technical Field

[0001] This invention relates to the field of road reinforcement equipment technology, and in particular to a road reinforcement device for construction. Background Technology

[0002] With the acceleration of urbanization and the gradual improvement of people's living conditions, more and more cities are building villas and other buildings in the suburbs. Before some suburbs were developed, the roads were mostly dirt roads. In order to ensure the construction progress, a solid road surface is usually built before construction.

[0003] In existing technologies, to ensure the progress of road repair, prefabricated road structures are commonly used for paving, with precast concrete slabs being the most common. To reduce transportation difficulties, existing precast concrete slabs are typically short in length, with multiple slabs laid sequentially to form a road surface for vehicles. However, these precast concrete slabs are usually simply placed on the ground without corresponding reinforcement or connection measures. Rainwater flows through the gaps between adjacent slabs onto the ground, and the slabs are prone to warping after being driven over by vehicles, which can affect the smoothness of the dirt road surface and negatively impact the normal use of the road structure. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a road surface reinforcement device.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a road surface reinforcement device, comprising a plurality of precast slabs arranged along the length of the road surface, adjacent precast slabs in the length direction of the road surface being hinged to each other, a T-shaped connecting block integrally formed on one side of each precast slab, a T-shaped connecting groove for the T-shaped connecting block to engage on the other side of each precast slab, adjacent precast slabs in the width direction of the road surface being connected to each other by the T-shaped connecting block and the T-shaped connecting groove, a positioning hole communicating with the T-shaped connecting groove being provided in the precast slab, and a locking component connected to the positioning hole being provided on the precast slab to achieve the reinforcement effect.

[0006] By adopting the above technical solution, two adjacent precast slabs along the road length direction are hinged to each other, and two adjacent precast slabs in the road width direction are connected by T-shaped connecting blocks and T-shaped connecting grooves. The locking component connects and reinforces the two precast slabs in the road width direction, ensuring the stability of the road reinforcement device composed of multiple precast slabs during use. This reduces the probability that rainwater seeps into the ground from the gaps between adjacent precast slabs, causing the precast slabs to easily lift under vehicle pressure and ultimately affecting the road surface smoothness and structural strength.

[0007] Furthermore, the T-shaped connecting block has an installation hole extending into the precast slab on the side away from the precast slab, corresponding to the positioning hole. The locking assembly includes a positioning post that slides with the inner wall of the mounting hole and is inserted into the positioning hole, and a tension spring fixed to the end of the positioning post away from the positioning hole. The end of the tension spring away from the mounting hole is fixed to the inner wall of the mounting hole. The top of the positioning post has an abutment groove with a right-angled trapezoidal cross-section. The inner wall of the abutment groove on the side away from the tension spring is an inclined surface. The locking assembly also includes a tightening bolt that is threaded to the top of the precast slab and extends into the abutment groove. The lower end of the tightening bolt abuts against the inclined surface of the abutment groove.

[0008] By adopting the above technical solution, during the gradual tightening of the clamping bolts, the lower end of the clamping bolts abuts against the inclined surface of the abutment groove, causing the positioning post to move towards the positioning hole. During this process, the tension spring gradually extends, and the positioning post engages with the positioning hole, thus ensuring the horizontal fixation between adjacent precast slabs. This, combined with the T-shaped connecting block and T-shaped connecting groove, ensures the stability of the road reinforcement device composed of multiple precast slabs during use. When disassembling adjacent precast slabs, workers only need to unscrew the clamping bolts. Because the lower end of the clamping bolts abuts against the inclined surface of the abutment groove, the positioning post gradually retracts into the mounting hole under the tension of the tension spring, allowing workers to pull out and separate the two adjacent precast slabs vertically.

[0009] Furthermore, a clearance ramp is provided at the intersection between the bottom of the precast slab and the side wall of the precast slab near its hinge axis. The first drainage ditch and the second drainage ditch are respectively provided on both sides of the road edge. A trapezoidal support pipe is provided between the first drainage ditch and the second drainage ditch. The cross-section of the trapezoidal support pipe is an isosceles trapezoid. The inclined surface of the trapezoidal support pipe cooperates with the clearance ramp. Dovetail-shaped connecting strips are fixed on the outer walls on both sides of the trapezoidal support pipe. The precast slab is provided with a dovetail-shaped connecting groove that communicates with the clearance ramp and engages with the dovetail-shaped connecting strip. Trapezoidal water inlets are provided at the positions corresponding to the first drainage ditch and the trapezoidal support pipe, and at the positions corresponding to the second drainage ditch and the trapezoidal support pipe. Multiple water inlets are provided at the top of the trapezoidal support pipe.

[0010] By adopting the above technical solution, the inclined surface facilitates workers to directly press the precast slab and retract the positioning post into the mounting hole. Once the positioning post aligns with the positioning hole, workers tighten the clamping bolt until its upper end is flush with the top of the precast slab. Under the pressure of the clamping bolt, the positioning post engages with the positioning hole, completing the connection and fixing between the two precast slabs. The trapezoidal support pipe provides excellent support for two adjacent flat precast slabs, ensuring the stability and structural strength of the precast slabs during use. The dovetail connecting strip on the trapezoidal support pipe engages with the dovetail connecting groove on the precast slab, ensuring the stability of the connection between the trapezoidal support pipe and the precast slab. The inlet allows rainwater seeping between two adjacent precast slabs to enter the trapezoidal support pipe and then exit through the trapezoidal inlet into the first or second drainage ditch, ensuring effective road drainage.

[0011] Furthermore, a T-shaped block is fixed on the side of the first drainage channel near the second drainage channel, which engages with the T-shaped connecting groove. A T-shaped groove is provided on the side of the second drainage channel near the first drainage channel, which engages with the T-shaped connecting block. A positioning hole communicating with the T-shaped groove is also provided at the position corresponding to the T-shaped block in the second drainage channel. An installation hole extending into the precast slab is also provided on the side of the T-shaped block away from the precast slab at the position corresponding to the positioning hole.

[0012] By adopting the above technical solution, the T-shaped block and T-shaped groove are designed to facilitate the connection of the precast slabs on both sides of the road surface with the first drainage ditch and the second drainage ditch respectively. The positioning holes and installation holes are designed to facilitate the locking components to fix the precast slabs with the first drainage ditch or the second drainage ditch.

[0013] Furthermore, a support member is fixed between the inner top wall and the inner bottom wall of the trapezoidal support tube, and the length direction of the support member is consistent with the length direction of the trapezoidal support tube.

[0014] By adopting the above technical solution, the support component plays a good supporting role for the trapezoidal support tube, ensuring the structural strength of the trapezoidal support tube and its supporting effect on the precast slab during use.

[0015] Furthermore, an abutting slope is provided at the intersection of the end of the positioning post away from the tension spring and the bottom surface of the positioning post.

[0016] Furthermore, each of the precast slabs is provided with an anchor rod through the middle, and a cover plate is fixed to the upper end of the anchor rod. The top of the precast slab is provided with a receiving groove for the cover plate to be inserted and fitted. The sidewall of the anchor rod is evenly provided with a plurality of anti-pull-out grooves to enhance the pull-out resistance of the anchor rod.

[0017] By adopting the above technical solution, in order to enhance the connection strength between the precast slab and the ground, after assembling multiple precast slabs, simply hitting the cover plate will allow the anchor rod to be inserted into the ground. The anti-backlash groove ensures the anchoring effect of the anchor rod and reduces the probability of the precast slab loosening.

[0018] Furthermore, the upper end of the cover plate is provided with a placement hole extending into the anchor rod. The side wall of the anchor rod is provided with a communication port communicating with the placement hole. There are two communication ports arranged symmetrically. The anchor rod is provided with a reinforcement component for strengthening the connection strength between it and the ground. The reinforcement component includes an installation unit. The installation unit includes a threaded post threadedly connected to the inner wall of the placement hole near its opening, a fixing rod fixed to the bottom wall of the placement hole, and an installation plate rotatably connected to the lower end of the threaded post. The reinforcement component also includes reinforcement units connected to both the installation plate and the fixing rod. There are two sets of reinforcement units, each located in one of the two communication ports. As the threaded post rotates, the two sets of reinforcement units gradually extend out of the communication ports and gradually insert into the soil.

[0019] Furthermore, the reinforcement unit includes a first connecting rod hinged to the mounting plate, a second connecting rod hinged to the fixed rod near its upper end, a reinforcement rod hinged to the end of the second connecting rod away from the fixed rod, and a third connecting rod hinged to the end of the reinforcement rod near the axis of the anchor rod. The end of the first connecting rod away from the mounting plate is hinged to the middle section of the second connecting rod. The third connecting rod is parallel to the second connecting rod. The reinforcement rod is parallel to the anchor rod. The end of the third connecting rod away from the reinforcement rod is hinged to the fixed rod.

[0020] By adopting the above technical solution, in order to further enhance the anchoring effect of the anchor rod, the workers only need to tighten the threaded column, which will cause the threaded column to move downward. Since the mounting plate is rotatably connected to the lower end of the threaded column, the mounting plate pushes the second link through the first link. Since the second link is hinged to both the reinforcing rod and the fixing rod, and the third link is parallel to the second link, and the reinforcing rod is parallel to the anchor rod, the reinforcing rod gradually moves away from the anchor rod and inserts into the soil, thus achieving the purpose of further reinforcing the precast slab and ensuring the effectiveness of the road reinforcement device.

[0021] Furthermore, the upper end of the threaded column is provided with an internal hexagonal groove.

[0022] In summary, the present invention has the following beneficial effects: 1. This application reduces the probability that rainwater seeps into the ground through the gaps between adjacent precast slabs, causing the precast slabs to warp under vehicle pressure and ultimately affecting the road surface smoothness and structural strength. 2. To further enhance the anchoring effect of the anchor rod, the worker only needs to tighten the threaded post, causing it to move downwards. Since the mounting plate is rotatably connected to the lower end of the threaded post, the mounting plate pushes the second link through the first link. Because the second link is hinged to both the reinforcing rod and the fixing rod, and the third link is parallel to the second link, and the reinforcing rod is parallel to the anchor rod, the reinforcing rod gradually moves away from the anchor rod and inserts into the soil, thus achieving the purpose of further reinforcing the precast slab and ensuring the effectiveness of the road reinforcement device.

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0026] like Figure 1-11 As shown in the figure, this application discloses a road surface reinforcement device, including a plurality of precast slabs 1 arranged along the length of the road surface. Adjacent precast slabs 1 along the length of the road surface are hinged to each other. A T-shaped connecting block 11 is integrally formed on one side of the precast slab 1, and a T-shaped connecting groove 12 for the T-shaped connecting block 11 to engage with the T-shaped connecting block 11 is provided on the other side of the precast slab 1. Adjacent precast slabs 1 along the width of the road surface are connected to the T-shaped connecting groove 12 through the T-shaped connecting block 11. A positioning hole 13 communicating with the T-shaped connecting groove 12 is provided in the precast slab 1, and a locking component 2 connected to the positioning hole 13 is provided on the precast slab 1 to achieve the reinforcement effect.

[0027] Two adjacent precast slabs 1 along the length of the road surface are hinged to each other, and two adjacent precast slabs 1 along the width of the road surface are connected by a T-shaped connecting block 11 and a T-shaped connecting groove 12. The locking component 2 connects and reinforces the two precast slabs 1 along the width of the road surface, ensuring the stability of the road surface reinforcement device composed of multiple precast slabs 1 during use. This reduces the probability that the precast slabs 1 will easily lift under the action of vehicles after rainwater seeps into the ground from the gaps between adjacent precast slabs 1, ultimately affecting the smoothness and structural strength of the road surface.

[0028] The T-shaped connecting block 11 has an installation hole 111 extending into the precast slab 1 at a position corresponding to the positioning hole 13 on the side away from the precast slab 1. The locking assembly 2 includes a positioning post 21 that slides with the inner wall of the mounting hole 111 and is inserted into the positioning hole 13, and a tension spring 22 that is fixed to the end of the positioning post 21 away from the positioning hole 13. The end of the tension spring 22 away from the mounting hole 111 is fixed to the inner wall of the mounting hole 111. The top of the positioning post 21 has an abutment groove 211 with a right-angled trapezoidal cross section. The inner wall of the abutment groove 211 away from the tension spring 22 is an inclined surface. The locking assembly 2 also includes a tightening bolt 23 that is threaded to the top of the precast slab 1 and extends into the abutment groove 211. The lower end of the tightening bolt 23 abuts against the inclined surface of the abutment groove 211.

[0029] During the gradual tightening of the clamping bolt 23, the lower end of the clamping bolt 23 abuts against the inclined surface of the abutment groove 211, causing the positioning post 21 to move towards the positioning hole 13. The tension spring 22 gradually extends during this process, and the positioning post 21 engages with the positioning hole 13, thus ensuring the horizontal fixation between two adjacent precast slabs 1. This, combined with the T-shaped connecting block 11 and the T-shaped connecting groove 12, ensures the stability of the road reinforcement device composed of multiple precast slabs 1 during use. When disassembling adjacent precast slabs 1, the worker only needs to unscrew the clamping bolt 23. Because the lower end of the clamping bolt 23 abuts against the inclined surface of the abutment groove 211, the positioning post 21 gradually retracts into the mounting hole 111 under the tension of the tension spring 22, allowing the worker to pull out and separate the two adjacent precast slabs 1 vertically.

[0030] A clearance ramp 14 is provided at the intersection between the bottom of the precast slab 1 and the side wall of the precast slab 1 near its hinge axis. A first drainage ditch 3 and a second drainage ditch 4 are respectively provided on both sides of the road edge. A trapezoidal support pipe 5 is provided between the first drainage ditch 3 and the second drainage ditch 4. The cross-section of the trapezoidal support pipe 5 is an isosceles trapezoid. The inclined surface of the trapezoidal support pipe 5 matches the clearance ramp 14. Dovetail connecting strips 51 are fixed on the outer walls on both sides of the trapezoidal support pipe 5. A dovetail connecting groove 15 is provided on the precast slab 1, which communicates with the clearance ramp 14 and is engaged with the dovetail connecting strip 51. A trapezoidal water inlet 6 is provided at the position corresponding to the first drainage ditch 3 and the trapezoidal support pipe 5, and at the position corresponding to the second drainage ditch 4 and the trapezoidal support pipe 5. Multiple water inlets 52 are provided at the top of the trapezoidal support pipe 5.

[0031] The inclined surface 14 allows workers to directly press the precast slab 1, causing the positioning post 21 to retract into the mounting hole 111. Once the positioning post 21 aligns with the positioning hole 13, workers tighten the clamping bolt 23 until its upper end is flush with the top of the precast slab 1. Under the pressure of the clamping bolt 23, the positioning post 21 engages with the positioning hole 13, completing the connection and fixing between the two precast slabs 1. The trapezoidal support tube 5 provides excellent support for the two adjacent flat precast slabs 1, ensuring the stability and structural strength of the precast slabs 1 during use. The dovetail connecting strip 51 on the trapezoidal support tube 5 engages with the dovetail connecting groove 15 on the precast slab 1, ensuring the stability of the connection between the trapezoidal support tube 5 and the precast slab 1. The inlet 52 allows rainwater that seeps between two adjacent precast slabs 1 to enter the trapezoidal support pipe 5, and then exits through the trapezoidal inlet 6 into the first drainage ditch 3 or the second drainage ditch 4, thus ensuring the drainage effect of the road surface.

[0032] A T-shaped block 31, which engages with a T-shaped connecting groove 12, is fixed on the side of the first drainage channel 3 closest to the second drainage channel 4. A T-shaped groove 41, which engages with a T-shaped connecting block 11, is provided on the side of the second drainage channel 4 closest to the first drainage channel 3. A positioning hole 13, communicating with the T-shaped groove 41, is also provided on the second drainage channel 4 at the position corresponding to the T-shaped block 31. An installation hole 111, extending into the precast slab 1, is also provided on the side of the T-shaped block 31 furthest from the precast slab 1 at the position corresponding to the positioning hole 13. The T-shaped block 31 and the T-shaped groove 41 facilitate the connection of the precast slabs 1 on both sides of the road surface to the first drainage channel 3 and the second drainage channel 4, respectively. The positioning hole 13 and the installation hole 111 facilitate the locking component 2 to fix the precast slab 1 to the first drainage channel 3 or the second drainage channel 4.

[0033] To ensure the structural strength of the trapezoidal support pipe 5 during use and its supporting effect on the precast slab 1, a support member 53 is fixed between the inner top wall and the inner bottom wall of the trapezoidal support pipe 5. The length direction of the support member 53 is consistent with the length direction of the trapezoidal support pipe 5. To facilitate the rapid installation of the precast slab 1, an abutting slope 24 is provided at the intersection between the end of the positioning post 21 away from the tension spring 22 and the bottom surface of the positioning post 21.

[0034] An anchor rod 7 is installed through the middle of each precast slab 1. A cover plate 71 is fixed to the upper end of the anchor rod 7. A receiving groove 16 is provided on the top of the precast slab 1 for the cover plate 71 to be inserted and fitted. Multiple anti-retraction grooves 72 are evenly provided on the side wall of the anchor rod 7 to enhance the pull-out resistance of the anchor rod 7. In order to enhance the connection strength between the precast slab 1 and the ground, after multiple precast slabs 1 are assembled, the anchor rod 7 can be inserted into the ground simply by hitting the cover plate 71. The anti-retraction grooves 72 ensure the anchoring effect of the anchor rod 7 and reduce the probability of the precast slab 1 loosening.

[0035] The upper end of the cover plate 71 is provided with a placement hole 711 extending into the anchor rod 7. The side wall of the anchor rod 7 is provided with a communication port 73 communicating with the placement hole 711. There are two communication ports 73 arranged symmetrically. The anchor rod 7 is provided with a reinforcement component 8 for strengthening the connection strength between it and the ground. The reinforcement component 8 includes an installation unit 81. The installation unit 81 includes a threaded post 811 threadedly connected to the inner wall of the placement hole 711 near its opening, a fixing rod 812 fixed to the inner bottom wall of the placement hole 711, and an installation plate 813 rotatably connected to the lower end of the threaded post 811. The reinforcement component 8 also includes a reinforcement unit 82 connected to both the installation plate 813 and the fixing rod 812. There are two sets of reinforcement units 82 located in the two communication ports 73 respectively. During the rotation of the threaded post 811, the two sets of reinforcement units 82 gradually extend out of the communication port 73 and gradually insert into the soil. In this embodiment, the upper end of the threaded post 811 is provided with an internal hexagonal groove 8111.

[0036] The reinforcement unit 82 includes a first link 821 hinged to the mounting plate 813, a second link 822 hinged to the fixed rod 812 near its upper end, a reinforcement rod 823 hinged to the end of the second link 822 away from the fixed rod 812, and a third link 824 hinged to the end of the reinforcement rod 823 near the axis of the anchor rod 7. The end of the first link 821 away from the mounting plate 813 is hinged to the middle section of the second link 822. The third link 824 is parallel to the second link 822. The reinforcement rod 823 is parallel to the anchor rod 7. The end of the third link 824 away from the reinforcement rod 823 is hinged to the fixed rod 812.

[0037] To further enhance the anchoring effect of the anchor rod 7, the worker only needs to tighten the threaded post 811 through the internal hexagonal groove 8111, thereby causing the threaded post 811 to move downward. Since the mounting plate 813 is rotatably connected to the lower end of the threaded post 811, the mounting plate 813 pushes the second connecting rod 822 through the first connecting rod 821. Since the second connecting rod 822 is hinged to the reinforcing rod 823 and the fixing rod 812, and the third connecting rod 824 is parallel to the second connecting rod 822, and the reinforcing rod 823 is parallel to the anchor rod 7, the reinforcing rod 823 gradually moves away from the anchor rod 7 and inserts into the soil, thus completing the purpose of further reinforcing the precast slab 1 and ensuring the effectiveness of the road reinforcement device.

[0038] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
