Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to a prefabricated temporary road structure based on solid waste modules. Background Technology

[0002] Prefabricated temporary pavement structures are temporary access systems composed of high-strength panels (such as steel plates and composite material panels), supporting structures (supports and joists), and connecting accessories (bolts and clips). They can be quickly assembled, disassembled, and reused, and are primarily used in construction and emergency rescue scenarios. During installation, the site is first cleaned and leveled. Then, the supporting structures are laid according to the design spacing and the height is calibrated. Subsequently, the prefabricated panels are placed one by one on the supporting structures, and adjacent panels are fixed with connecting accessories to ensure seamlessness and stability. Finally, the flatness and load-bearing capacity are checked, and the system can be put into use after confirmation.

[0003] When multiple prefabricated temporary pavement blocks are spliced ​​together, they are prone to misalignment when subjected to force. The core reason is that the connection strength and support stability at the splicing point are insufficient, and they cannot resist the horizontal thrust and vertical shear force when vehicles pass by. This can easily cause bumps and impacts when vehicles pass by, affecting traffic safety. Utility Model Content

[0004] The purpose of this invention is to provide a prefabricated temporary road structure based on solid waste modules to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, a prefabricated temporary road structure based on solid waste modules is provided, including a prefabricated road surface A, a prefabricated road surface B on one side of the prefabricated road surface A, and a docking buffer telescopic mechanism is installed between the prefabricated road surface B and the prefabricated road surface A. The prefabricated road surface A includes a prefabricated slab, and a docking groove is opened on the side wall of the prefabricated slab, and a docking end is installed inside the docking groove. Multiple sets of lifting holes are equally spaced on the prefabricated slab, and metal guard plates are fixed at both ends of the prefabricated slab.

[0006] Furthermore, the precast pavement A also includes a water channel and a buffer seat, and the water channel is opened on the surface of the precast slab and is inclined.

[0007] Furthermore, the buffer seat is fixed to the bottom of the precast slab, and multiple sets of buffer openings are equidistantly provided on the buffer seat, the buffer openings being regular hexagonal.

[0008] Furthermore, the docking buffer telescopic mechanism includes a prefabricated docking seat, and both ends of the prefabricated docking seat are provided with docking ends, and both the docking ends and the docking groove are dovetail-shaped.

[0009] Furthermore, the docking buffer telescopic mechanism also includes a buffer sleeve, which is a rectangular structure made of rubber, and a prefabricated docking seat is inserted inside the buffer sleeve.

[0010] Furthermore, the buffer sleeve has end sleeves on both sides, and the end sleeves are fitted onto the outside of the mating end. The buffer sleeve also has expansion joint filling seats on both the upper and lower surfaces.

[0011] Furthermore, the expansion joint filler is sandwiched between precast pavement A and precast pavement B, and the length of the expansion joint filler is consistent with that of precast pavement A and precast pavement B.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This solution achieves efficient mechanical interlocking by connecting the prefabricated docking seat and docking end on the docking buffer telescopic mechanism with the docking grooves on prefabricated pavement A and prefabricated pavement B through an interlocking fit. When a vehicle travels on the road, the horizontal shear force and vertical warping force generated will directly act on the connection point. The tight fit between the docking end and the docking groove forms a robust rigid connection point, which can effectively resist and disperse these external forces, and prevent possible lateral and longitudinal misalignment and vertical warping between prefabricated pavement A and prefabricated pavement B, thus ensuring the integrity, flatness and driving safety of the temporary pavement.

[0014] 2. This solution utilizes the fact that the rigid precast pavement A and precast pavement B will generate huge internal stress when they expand; while the soft joint filler is compressed and absorbs most of the expansion stress through its own deformation, perfectly protecting the core connecting components and pavement panels; avoiding the situation where precast pavement A and precast pavement B are rigidly squeezed together, and the expansion force would force the two panels to tilt upwards or downwards, seriously affecting driving safety and stability.

Detailed Implementation

[0021] Please see Figure 1-5 This utility model provides a prefabricated temporary road structure based on solid waste modules, including a prefabricated road surface A100, a prefabricated road surface B200 on one side of the prefabricated road surface A100, and a docking buffer telescopic mechanism 300 installed between the prefabricated road surface B200 and the prefabricated road surface A100. The prefabricated road surface A100 includes a prefabricated slab 11, and a docking groove 12 is opened on the side wall of the prefabricated slab 11. At the same time, a docking end 32 is installed inside the docking groove 12. Multiple sets of lifting holes 14 are equally spaced on the prefabricated slab 11, and metal guard plates 15 are fixed at both ends of the prefabricated slab 11.

[0022] Working principle: Precast pavement A100 and precast pavement B200 are first hoisted to the target position using hoisting equipment. At this time, the docking buffer telescopic mechanism 300 is used to connect precast pavement A100 and precast pavement B200 together. Specifically, the docking ends 32 of the precast docking seat 31 on the docking buffer telescopic mechanism 300 are respectively inserted into the docking grooves 12 opened on the side walls of precast pavement A100 and precast pavement B200. At the same time, the buffer sleeve 33 is sleeved on the outside of the docking end 32. The buffer sleeve 33 is provided with two sets of contraction joint filling seats 35, which are clamped between precast pavement A100 and precast pavement B200. When precast pavement A100 and precast pavement B200 expand in summer, the soft contraction joint filling seats 35 can be squeezed, directly squeezing the precast pavement A100 and precast pavement B200, causing the pavement to bulge and break.

[0023] The prefabricated docking seat 31 and docking end 32 on the docking buffer telescopic mechanism 300, together with the docking groove 12 on the prefabricated pavement A100 and prefabricated pavement B200, form an interlocking mechanism, achieving efficient mechanical interlocking. During rapid assembly, this interlocking method eliminates the need for cumbersome bolt tightening or welding; simply aligning the docking end 32 and embedding it into the docking groove 12 is sufficient, greatly improving construction speed. More importantly, when vehicles travel on the road, the horizontal shear force and vertical warping force generated will directly act on the connection point. At this time, the tight fit between the docking end 32 and the docking groove 12 forms a robust rigid connection point, which can effectively resist and disperse these external forces, just like setting multiple mortise and tenon joints between two pavement panels. This prevents possible lateral and longitudinal misalignment and vertical warping between the prefabricated pavement A100 and prefabricated pavement B200, ensuring the integrity, flatness, and driving safety of the temporary pavement.

[0024] As a preferred embodiment, the precast pavement A100 also includes a water channel 13 and a buffer seat 16, and the water channel 13 is opened on the surface of the precast slab 11, while the water channel 13 is inclined.

[0025] like Figure 1 and Figure 5 As shown: The inclined water channel 13 can significantly accelerate the diversion and discharge of water on the road surface by utilizing gravity, effectively preventing rainwater from accumulating on the surface of the precast slab 11, thereby greatly improving the anti-skid performance of the road surface and driving safety.

[0026] The buffer seat 16 is fixed to the bottom of the precast slab 11, and multiple sets of buffer openings 161 are equally spaced on the buffer seat 16, with the buffer openings 161 being regular hexagonal.

[0027] like Figures 1-5 As shown: The buffer seat 16 fixed to the bottom of the precast slab 11 and the multiple sets of regular hexagonal buffer openings 161 arranged at equal intervals on it together constitute a high-strength honeycomb support structure. The buffer seat 16 is made of high-strength rubber, which can not only evenly distribute the upper load to the foundation, greatly enhance the load-bearing capacity and deformation resistance of the precast slab 11, but also form a tight fit with the soft foundation, producing an excellent anchoring effect, thereby effectively suppressing the horizontal displacement and settlement of the precast slab 11 under vehicle load, and ensuring the firmness, stability and flatness of the entire temporary road surface.

[0028] As a preferred embodiment, the docking buffer telescopic mechanism 300 includes a prefabricated docking seat 31, and both ends of the prefabricated docking seat 31 are provided with docking ends 32, and both the docking ends 32 and the docking groove 12 are dovetail-shaped.

[0029] The docking buffer telescopic mechanism 300 also includes a buffer sleeve 33, which is a rectangular structure made of rubber, and a prefabricated docking seat 31 is inserted inside the buffer sleeve 33.

[0030] Both sides of the buffer sleeve 33 are provided with end sleeves 34, and the end sleeves 34 are fitted onto the outside of the mating end 32. Both the upper and lower surfaces of the buffer sleeve 33 are provided with expansion joint filling seats 35.

[0031] The expansion joint filler 35 is sandwiched between the precast pavement A100 and the precast pavement B200, and the expansion joint filler 35 has the same length as the precast pavement A100 and the precast pavement B200.

[0032] like Figure 1-4 As shown: When the rigid precast pavement A100 and B200 expand, they generate significant internal stress. The flexible joint filler 35, compressed like a spring, absorbs most of this expansion stress through its own deformation, perfectly protecting the core connecting components and the pavement slab. This prevents the rigid compression of precast pavement A100 and B200, which could cause the two slabs to warp upwards or downwards, severely impacting driving safety and stability. The joint filler 35 converts the horizontal expansion force into vertical compression deformation, ensuring the two pavement slabs remain on the same plane, greatly maintaining the continuity and smoothness of the temporary pavement. During thermal expansion, the joint filler 35 is tightly compressed between precast pavement A100 and B200. This pressure makes it contact the side of the plate more tightly, forming a dynamic sealing effect; this can effectively prevent sand, soil and other debris from getting into the gap; when the temperature drops and the road surface contracts, the contraction joint filler 35 rebounds, which can also prevent debris from getting stuck in the gap, ensuring the normal function of the contraction joint; as the first line of defense, the contraction joint filler 35 bears the main compression and friction; it protects the more expensive mating end 32 and buffer sleeve 33 from direct rigid impact and excessive wear; when the vehicle drives over the road joint, the soft contraction joint filler 35 provides a smooth transition, avoiding direct impact between the wheel and the hard edge; even in the expanded state, the joint becomes flexible due to the presence of the filler, which significantly reduces driving noise and the "bumpy" impact, improving the driving quality.

[0033] Before laying precast pavement A100 and precast pavement B200, the ground to be paved must first be leveled. The paving material for the foundation can be a solid waste base, which includes municipal solid waste pellets and graphite tailings. The slag or fly ash produced by municipal solid waste incineration must first undergo harmless treatment to remove heavy metals and harmful organic matter before it can be used as an auxiliary material, mainly for low-grade pavements or pavement base and subbase. Graphite tailings have a relatively stable composition. After pretreatment such as crushing, screening, and purification, they can be used as aggregates or fillers in pavement structures, and their application scenarios are wider than those of incineration waste pellets. Some graphite tailings have good hardness and wear resistance, and can replace natural sand and gravel for pavement base or subbase to improve the structural load-bearing stability. Ultrafine graphite tailings powder can also be used as filler to improve the crack resistance and aging resistance of asphalt mixtures.
