Description

Technical Field

[0001] This invention relates to the field of public road technology, specifically to a method and equipment for constructing modular roads. Background Technology

[0002] After a highway is built and opened to traffic, its quality will gradually decrease due to wear and impact from wheels, erosion and weathering from natural forces such as rainstorms, floods, wind and sand, snow, sun, and melting ice, as well as human damage and defects left over from construction.

[0003] Over time, the following conditions occur on the road surface: 1. Sections of the road surface are prone to bulging, leading to frequent vehicle bounces. This can easily cause traffic accidents, reduce driving speed, and affect road surface usability and vehicle lifespan. 2. During vehicle operation, high temperatures and frequent braking cause ruts, bumps, cracks, and other defects in the road surface.

[0004] The traditional repair method involves first using a bulldozer to remove the damaged section of the road surface to create a pit. A layer of fine sand and gravel is then laid inside the pit, followed by concrete pouring. Workers level the concrete, cover it with a waterproof tarpaulin, and wait for it to harden. Then, asphalt and gravel are laid on top, and a roller compactor is used to repeatedly compact and level the asphalt and gravel. Traffic is allowed to resume after the asphalt has hardened.

[0005] The aforementioned methods involve long construction periods, requiring excessive time for concrete and asphalt to harden, and necessitate the use of large construction vehicles, resulting in high maintenance costs. Therefore, a new type of prefabricated pavement is proposed to address the issues of high maintenance costs and long construction periods. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides a construction method for prefabricated road construction equipment:

[0007] Step 1: Based on the thickness of the prefabricated road slab layers and the fill layer, use a bulldozer to remove the raised, cracked, and bulging areas of the old road surface. Mill and excavate the old road surface to remove the raised, bulging, and cracked areas. After the bulldozer has cleaned up the surface, the underlying base layer is exposed. Then, the removed road debris and fragments are cleaned up, forming a rectangular area to be repaired on the road surface.

[0008] Step two involves base treatment, including load-bearing capacity testing of the base pavement, repairing the base to meet required standards based on the test results, and determining the size and shape of the required slabs according to the pavement's load-bearing capacity and intended use, and then prefabricating reinforced concrete slabs.

[0009] Step 3: Lay a 3mm thick layer of fine stone asphalt on the concrete slab and wait for the asphalt to harden.

[0010] Step four: While waiting for the asphalt to harden, lay supports on the base layer according to the size of the concrete slabs. After the asphalt hardens, lay the precast reinforced concrete slabs on the supports and level the concrete slabs so that each concrete slab is on the same horizontal plane, thus forming a slab layer.

[0011] Step 5: Mix the high-strength micro-foamed mortar according to the mix ratio, and pour the mortar between the base layer and the slab layer to form a filling layer between the base layer and the slab layer.

[0012] Step 6: Inject tack coat into the gaps between the concrete slabs. After the tack coat has hardened, apply high-elasticity sealant over it to seal the gaps between the concrete slabs.

[0013] Step 7: Place warning signs around the repaired area. After the high-elasticity sealant has hardened, remove the warning signs and open the road to traffic.

[0014] A modular road construction device includes multiple poles arranged in an equidistant matrix to form a support for concrete slabs. Each pole has an adjustment section at its center, with a cross-shaped groove along its length. A cross-shaped slider slides within the groove, with its end extending beyond the groove and connected to a receiving plate. A partition plate is connected to the top of the receiving plate, and the bottom edge of the concrete slab overlaps the receiving plate. Adjacent concrete slabs are separated by partition plates.

[0015] The cross groove is provided with a vertical screw rod. The lower end of the screw rod is pivotally connected to the bottom of the inner wall of the cross groove. The upper end of the screw rod is threaded through the cross slider and extends to the top of the insertion rod. The top of the screw rod is provided with a rod cap.

[0016] It also includes a connecting plate, which is located between two adjacent inserts. The end of the connecting plate can mate with the receiving piece, and a level is embedded in the top of the connecting plate.

[0017] Preferably, the front end of the receiving plate is used to dock with the connecting plate, the rear end of the receiving plate is connected to the insertion groove, the end of the cross slider is inserted into the insertion groove, the partition is provided with multiple liquid outlet holes at equal intervals, the multiple liquid outlet holes are interconnected, the rear end of the receiving plate is connected to a flexible tube, the flexible tube is connected to the liquid outlet hole, and the upper end of the flexible tube extends to the top of the insertion rod.

[0018] Preferably, the bottom of the receiving plate is raised, and a sliding cavity is formed in the raised part. An iron pin is slidably fitted in the sliding cavity. A spring is connected between the pin and the inner wall of the sliding cavity. The end of the connecting plate is provided with a slot corresponding to the sliding cavity. A magnet is embedded in the slot. Under the influence of magnetic force, the pin can be attracted into the slot.

[0019] Preferably, the connecting plate is in the shape of an inverted "T" and consists of a longitudinal part and a transverse part. The longitudinal part is welded to the transverse part, the bottom edge of the concrete slab overlaps the transverse part, and the longitudinal part is aligned with the partition.

[0020] Preferably, a large hole adapted to the screw is provided at the center of the top of the insertion rod, and a small hole adapted to the flexible hose is provided at the top of the insertion rod.

[0021] Preferably, the cross slider has a large threaded hole at its center and a small threaded hole at its end. The screw rod is threadedly connected to the large threaded hole. A bolt is provided above the end of the cross slider. The lower end of the bolt passes through the insertion groove and is threadedly connected to the small threaded hole. A ring is connected between the ends of the cross slider, and the ring surrounds the adjustment section.

[0022] Preferably, the insert rod body and the groove located below the adjustment section are provided with a load-bearing rod.

[0023] This invention provides a method and equipment for constructing modular roads. It offers the following advantages:

[0024] This modular road construction method and equipment uses insert rods, cross-shaped sliders, receiving plates, and connecting plates to form a support structure for precast concrete slabs. The height of the cross-shaped sliders is adjusted using a spirit level and screws to ensure all concrete slabs are on the same horizontal plane, thus forming slab layers. Mortar is injected between the slab layers and the base layer as a filler layer, providing a vibration damping effect on the road surface. This method replaces traditional road maintenance methods, accelerating the road repair process and reducing the required construction time. It also increases maintenance efficiency, reduces the use of construction vehicles, and ultimately lowers maintenance costs. Attached Figure Description

[0032] Examples of embodiments of the present invention Figure 1-6 As shown, a construction method for using prefabricated road construction equipment is provided:

[0033] Step 1: Based on the thickness of the prefabricated road slab layers and the fill layer, use a bulldozer to remove the raised, cracked, and bulging areas of the old road surface. Mill and excavate the old road surface to remove the raised, bulging, and cracked areas. After the bulldozer has cleaned up the surface, the underlying base layer is exposed. Then, the removed road debris and fragments are cleaned up, forming a rectangular area to be repaired on the road surface.

[0034] Step two involves base treatment, including load-bearing capacity testing of the base pavement, repairing the base to meet required standards based on the test results, and determining the size and shape of the required slabs according to the pavement's load-bearing capacity and intended use, and then prefabricating reinforced concrete slabs.

[0035] Step 3: Lay a 3mm thick layer of fine stone asphalt on the concrete slab and wait for the asphalt to harden.

[0036] Step four: While waiting for the asphalt to harden, lay supports on the base layer according to the size of the concrete slabs. After the asphalt hardens, lay the precast reinforced concrete slabs on the supports and level the concrete slabs so that each concrete slab is on the same horizontal plane, thus forming a slab layer.

[0037] Step 5: Mix the high-strength micro-foamed mortar according to the mix ratio, and pour the mortar between the base layer and the slab layer to form a filling layer between the base layer and the slab layer.

[0038] Step 6: Inject tack coat into the gaps between the concrete slabs. After the tack coat has hardened, apply high-elasticity sealant over it to seal the gaps between the concrete slabs.

[0039] Step 7: Place warning signs around the repaired area. After the high-elasticity sealant has hardened, remove the warning signs and open the road to traffic.

[0040] A modular road construction equipment includes multiple insertion poles 1 arranged in an equidistant matrix. The insertion poles 1 form a support frame for concrete slabs. An adjustment section 11 is welded to the center of each insertion pole 1. The adjustment section 11 has a cross-shaped groove 12 along its length, within which a cross-shaped slider 2 slides. The end of the cross-shaped slider 2 extends beyond the cross-shaped groove 12 and is fixedly mounted with a receiving plate 3. A spacer 32 is welded to the top of the receiving plate 3. The bottom edge of the concrete slab overlaps the receiving plate 3, and adjacent concrete slabs are separated by the spacer 32. The lower end of each insertion pole 1 is inserted into the base layer.

[0041] A vertical screw 6 is provided inside the cross slide groove 12. The lower end of the screw 6 is pivotally connected to the bottom of the inner wall of the cross slide groove 12. The upper end of the screw 6 is threaded through the cross slide block 2 and extends to the top of the insert rod 1. A rod cap 61 is welded to the top of the screw 6. The rod cap 61 is provided to facilitate the worker to rotate the screw 6.

[0042] It also includes a connecting plate 4, located between two adjacent inserts 1. The end of the connecting plate 4 can mate with the receiving piece 3, and a level 5 is embedded in the top of the connecting plate 4. Figure 2 As can be seen, a groove is formed at the top of the connecting plate 4, and the level 5 is placed inside this groove. After the level 5 is no longer in use, it is removed from the top of the connecting plate 4.

[0043] The support column, consisting of insert rod 1, cross slider 2, and receiving plate 3, supports the corners of the precast concrete slab. This allows for a gap between the concrete slab and the base layer, facilitating subsequent mortar pouring.

[0044] The connecting plate 4 connects all the supporting columns together. After the connecting plate 4 is aligned with the receiving plate 3, observe whether the bubble in the level 5 is centered. This is used to determine whether the height of each concrete slab is the same.

[0045] The front end of the receiving plate 3 is used to mate with the connecting plate 4, and the rear end of the receiving plate 3 is welded with a insertion groove 31, into which the end of the cross slider 2 is inserted. The partition plate 32 has multiple liquid outlet holes 321 at equal intervals, and the multiple liquid outlet holes 321 are interconnected. A flexible hose 33 is fixedly installed at the rear end of the receiving plate 3, and the flexible hose 33 is connected to the liquid outlet holes 321. The upper end of the flexible hose 33 extends above the insertion rod 1.

[0046] Combined with appendix Figure 2 Each concrete slab forms a slab layer. Mortar is poured between the slab layer and the base layer. After the mortar solidifies, the gaps between the slabs are filled. Tack coat is injected into hose 33 and sprayed out from the outlet hole 321. The tack coat accumulates continuously in the gaps between the concrete slabs until it is flush with the upper surface of the concrete slab.

[0047] This setup replaces the traditional method of dripping tack coat into the gaps between concrete slabs. It ensures the tack coat fills all areas of the gaps precisely, preventing air bubbles from remaining or the tack coat from failing to reach deeper areas. This improves the adhesion between slabs.

[0048] The bottom of the receiving plate 3 is raised, and a sliding cavity 34 is formed in the raised part. An iron pin 36 is slidably fitted in the sliding cavity 34. A spring 35 is welded between the pin 36 and the inner wall of the sliding cavity 34. The end of the connecting plate 4 has a slot 41 corresponding to the sliding cavity 34. A magnet 42 is embedded in the slot 41. Under the influence of magnetic force, the pin 36 can be attracted into the slot 41. This serves to fix the receiving plate 3 and the connecting plate 4.

[0049] The connecting plate 4 is in the shape of an inverted "T" and consists of a longitudinal part and a transverse part. The longitudinal part is welded to the transverse part, the bottom edge of the concrete slab overlaps the transverse part, and the longitudinal part is aligned with the partition 32.

[0050] The top center of the insertion rod 1 has a large hole 15 that matches the screw 6, and the top of the insertion rod 1 has a small hole 16 that matches the hose 33.

[0051] A large threaded hole 21 is provided in the center of the cross slider 2, and a small threaded hole 22 is provided at the end of the cross slider 2. The screw 6 is threadedly connected to the large threaded hole 21. A bolt 24 is provided above the end of the cross slider 2. The lower end of the bolt 24 passes through the insertion groove 31 and is threadedly connected to the small threaded hole 22. A ring 23 is connected between the ends of the cross slider 2, and the ring 23 surrounds the adjustment section 11.

[0052] The insert rod 1 has a groove 13 located below the adjustment section 11, and a load-bearing rod 14 is welded into the groove 13.

[0053] Working principle: Based on the dimensions of the precast concrete slabs, vertical holes are first drilled in the base layer, and the lower end of the insert rod 1 is placed into the hole. The lower end of the load-bearing rod 14 contacts the surface of the base layer. The receiving plate 3 is fixed to the end of the cross slider 2.

[0054] Next, place the connecting plate 4 between the two insert rods 1, and insert the pin 36 in the receiving piece 3 into the slot 41 at the end of the connecting plate 4. Visually inspect the level 5 and manually rotate the screw 6 to adjust the height of the cross slider 2.

[0055] Raise the receiving plate 3 and connecting plate 4 to the required height. Remove the level 5 from the top of the connecting plate 4. Pass the hose 33 through the small hole 16. Repeat the above steps to assemble the bracket on the base layer and place the concrete slab on the bracket. Finally, apply the tack coat.

[0056] In summary, this modular road construction method and equipment, through the cooperation of insert rod 1, cross slider 2, receiving plate 3, and connecting plate 4, forms a support frame for precast concrete slabs. The height of the cross slider 2 is adjusted using a level 5 and screw rod 6, ensuring that all concrete slabs are on the same horizontal plane to form a slab layer. Mortar is injected between the slab layer and the base layer as a filler layer, providing a vibration damping effect on the road surface. This method replaces traditional road maintenance methods, accelerating the road repair process and reducing the required construction time. It also increases maintenance efficiency, reduces the use of construction vehicles, and ultimately lowers maintenance costs.
