Description

Technical Field

[0001] This invention patent relates to the technical field of plastic paving. Specifically, it relates to a plastic paving method for the edge of an overpass bridge. Background Art

[0002] Plastic paving is a method of laying the ground using plastic materials, which has the advantages of being green and environmentally friendly, ultra-light and ultra-thin, having strong anti-slip properties, and being fireproof and flame-retardant. It is widely used in various pedestrian activity venues.

[0003] After long-term use, the plastic surface layer will face problems such as hardness change, fading, blistering, etc. It may even crack and detach, directly exposing the surface layer such as concrete, posing certain potential safety hazards for passage.

[0004] In the existing paving methods, it is common to directly pour concrete to form a concrete layer after excavating a trench at the construction site. Then, after spraying an adhesive on the concrete surface layer, the plastic surface layer is laid. Although this method has a short construction period and high efficiency, due to the different characteristics of different ground base surfaces and the lack of specific construction for each layer, after paving, it is prone to cracking, peeling, and breaking away, unable to meet the requirements of the overall construction quality. Summary of the Invention

[0005] The purpose of this invention is to provide a plastic paving method for the edge of an overpass bridge, aiming to solve the problem of poor overall construction quality in the plastic paving construction for the edge of an overpass bridge in the existing technology.

[0006] This invention is implemented as follows and includes construction steps:

[0007] 1), Clean up the sundries at the construction site on the edge of the overpass bridge to expose the plain soil layer of the construction site;

[0008] 2), Use a vibrating roller to vibrate and compact the plain soil layer to make the plain soil layer reach the set density;

[0009] 3), Lay gravel on the plain soil layer to form a gravel layer. There are gravel intervals in the gravel layer. Use the vibrating roller to vibrate and compact the gravel layer; Spread sand on the compacted gravel layer and sweep the sand to make the sand embed in the gravel gaps in the gravel layer;

[0010] 4), Pour and lay concrete on the gravel layer to form a concrete layer;

[0011] 5), Lay a bonding adhesive on the concrete layer to form a bonding layer on the concrete layer;

[0012] 6), Arrange a plastic surface layer on the bonding layer, and use a rolling cylinder to roll and press along the plastic surface layer to make the plastic surface layer combine with the bonding layer as a whole.

[0013] Further, in the construction step 1), an excavator is used to clean up sundries on the construction site so that the plain soil layer is exposed.

[0014] Further, in the construction step 3), after the sand material is embedded in the gravel intervals, a water sprinkler is used to spray water on the gravel layer, and the water penetrates into the gravel intervals to moisten the sand material embedded in the gravel intervals.

[0015] Further, in the construction step 3), after spraying water on the gravel layer, a vibrating roller is used to vibrate and roll the gravel layer multiple times.

[0016] Further, in the construction step 4), after a concrete layer is formed on the gravel layer, a plastic cloth is covered on the concrete layer. The plastic cloth covers the concrete layer, and water is regularly sprayed on the plastic cloth to cure the concrete layer. After the concrete layer is cured for the set time, the plastic cloth is removed.

[0017] Further, in the construction step 5), after the bonding adhesive is laid on the concrete layer, a trowel is used to horizontally scrape the bonding adhesive so that the bonding adhesive is evenly spread to form the bonding layer.

[0018] Further, in the construction step 6), the plastic surface layer is rolled and paved on the bonding layer in a rolling manner so that the plastic surface layer is laid flat on the bonding layer.

[0019] Further, in the construction step 6), during the process of rolling and paving the plastic surface layer on the bonding surface, the rolling cylinder synchronously rolls and presses against the plastic surface layer so that the plastic surface layer placed on the bonding layer is integrated with the bonding layer.

[0020] Further, in the construction step 3), before laying the gravel layer, elastic rods arranged longitudinally are provided on the plain soil layer. The lower part of the elastic rod has an insertion section, and the insertion section is inserted and fixed in the plain soil layer; the upper part of the elastic rod has a bending section, and the bending section is arranged in multiple bends; a plurality of elastically arranged elastic strips extend outward from the outer periphery of the bending section;

[0021] In the construction step 3), after the gravel layer is formed on the plain soil layer, the bending section is wrapped in the gravel layer and is compressed and deformed under the pressure of the gravel layer. The elastic strips extend away from the bending section and are embedded in the gravel layer and are compressed and deformed under the pressure of the gravel layer.

[0022] Further, in the construction step 3), a flexible mesh layer made of an elastic material is connected to the top of the bending section. After the gravel layer is formed on the plain soil layer, the flexible mesh layer is laid on the top of the gravel layer;

[0023] In the construction step 4), when the concrete layer is formed on the gravel layer, the bottom of the concrete layer is embedded downward into the gravel intervals of the gravel layer, and the flexible mesh layer is embedded in the concrete layer.

[0024] Compared with the prior art, the plastic pavement laying method for the bridge side of the overpass provided by the present invention has the following construction advantages:

[0025] 1), By thoroughly cleaning sundries, the plain soil layer is firmly combined with the subsequently laid materials, and a vibrating roller is used to make the plain soil layer reach the set compactness, effectively enhancing the stability and bearing capacity of the base layer, and solving the problems of uneven settlement and insufficient bearing capacity caused by improper treatment of the base layer.

[0026] 2), Spread sand on the gravel layer, and enhance the stability and drainage performance of the gravel layer by vibrating and rolling and sweeping the sand into the gravel gaps, so that the concrete layer on the gravel layer can reduce the soaking and erosion of rainwater, avoid perforation and cracking, thereby providing a good laying foundation for the bonding glue, improving the bonding strength between layers, and making the layer-to-layer combination firm and not easy to separate.

[0027] 3), The bonding layer and the plastic surface layer are closely combined into one body, improving the flatness of the plastic pavement, enhancing the durability and crack resistance of the plastic surface layer, and ensuring the overall construction quality of the plastic pavement on the bridge side of the overpass.

[0035] Refer to Figures 1-3 As shown, it is a preferred embodiment provided by the present invention.

[0036] The plastic paving method for the bridge side of the overpass includes construction steps:

[0037] 1) Clean the sundries in the construction site on the bridge side of the overpass to expose the plain soil layer of the construction site;

[0038] 2) Use a vibrating roller to vibrate and compact the plain soil layer to make the plain soil layer reach the set density;

[0039] 3) Lay gravel on the plain soil layer to form a gravel layer. There are gravel intervals in the gravel layer. Use a vibrating roller to vibrate and compact the gravel layer; Spread sand on the compacted gravel layer and sweep the sand to make the sand embed in the gravel gaps in the gravel layer;

[0040] 4) Pour and lay concrete on the gravel layer to form a concrete layer;

[0041] 5) Lay a bonding adhesive on the concrete layer to form a bonding layer on the concrete layer;

[0042] 6) Arrange a plastic surface layer on the bonding layer and use a rolling cylinder to roll and press along the plastic surface layer to make the plastic surface layer and the bonding layer combine into one.

[0043] The above-provided plastic paving method for the bridge side of the overpass has the following construction advantages:

[0044] 1) By thoroughly cleaning the sundries, the plain soil layer is firmly combined with the subsequently laid materials. Using a vibrating roller to make the plain soil layer reach the set density effectively enhances the stability and bearing capacity of the base layer, and solves the problems of uneven settlement and insufficient bearing capacity caused by improper treatment of the base layer.

[0045] 2) Spread sand on the gravel layer, and embed the sand into the gaps between the gravels through vibration rolling and sweeping, which enhances the stability and drainage performance of the gravel layer, enables the concrete layer on the gravel layer to reduce the soaking and erosion of rainwater, avoids perforation and cracking, thus providing a good laying foundation for the bonding adhesive, improving the bonding strength between layers, and making the interlayer bonding firm and not easy to separate.

[0046] 3) The bonding layer and the plastic surface layer are closely combined into one body, improving the flatness of the plastic paving, enhancing the durability and crack resistance of the plastic surface layer, and ensuring the overall construction quality of the plastic paving on the side of the overpass.

[0047] In this embodiment, in construction step 1), an excavator is used to clean up sundries on the construction site so that the plain soil layer is exposed. In this way, the cleaning efficiency of the construction site is effectively improved, ensuring thorough cleaning and providing a good foundation for subsequent construction.

[0048] In this embodiment, in construction step 3), after the sand is embedded in the gravel intervals, a water truck is used to spray water on the gravel layer, and the water seeps into the gravel intervals to moisten the sand embedded in the gravel intervals. In this way, the bonding force between the sand and the gravel layer is enhanced, the loss of the sand is prevented, and the long-term stability of the gravel layer is maintained.

[0049] In this embodiment, in construction step 3), after spraying water on the gravel layer, a vibrating roller is used to vibrate and roll the gravel layer multiple times. By further compacting the gravel layer, the density and bearing capacity of the gravel layer are improved, providing a solid support for subsequent laying.

[0050] In this embodiment, in construction step 4), after a concrete layer is formed on the gravel layer, a plastic cloth is covered on the concrete layer. The plastic cloth covers the concrete layer, and water is regularly sprayed on the plastic cloth to cure the concrete layer. After the concrete layer is cured for the set time, the plastic cloth is removed. By maintaining the wet state of the concrete layer, the uniform hardening of the concrete is promoted, and the strength and durability of the concrete layer are improved.

[0051] In this embodiment, in construction step 5), after the bonding adhesive is laid on the concrete layer, a squeegee is used to horizontally scrape the bonding adhesive to make the bonding adhesive spread evenly to form a bonding layer. In this way, the uniformity and bonding strength of the bonding layer are improved, providing a good bonding foundation for the laying of the plastic surface layer.

[0052] In this embodiment, in construction step 6), the plastic surface layer is rolled and paved on the bonding layer so that the plastic surface layer is laid flat on the bonding layer. In this way, the laying efficiency and flatness of the plastic surface layer are improved, providing convenience for subsequent pressing.

[0053] In this embodiment, in construction step 6), during the process of rolling and spreading the plastic surface layer on the bonding surface, the rolling cylinder rolls synchronously and presses against the plastic surface layer, so that the plastic surface layer placed on the bonding layer is integrated with the bonding layer. Through the pressing of the rolling cylinder, the adhesion between the plastic surface layer and the bonding layer is enhanced, ensuring the stability and durability of the plastic paving.

[0054] In this embodiment, in construction step 3), before laying the gravel layer, elastic rods arranged longitudinally are provided on the plain soil layer. The lower part of the elastic rod has an insertion section, and the insertion section is inserted and fixed in the plain soil layer; the upper part of the elastic rod has a bending section, and the bending section is arranged in multiple bends; multiple elastic strips arranged in a bend extend outwards from the outer periphery of the bending section;

[0055] In construction step 3), when the gravel layer is formed on the plain soil layer, the bending section is wrapped in the gravel layer and is compressed and deformed under the pressing of the gravel layer. The elastic strips extend away from the bending section and are embedded in the gravel layer and are compressed and deformed under the pressing of the gravel layer.

[0056] By setting the elastic rods, the connection strength between the gravel layer and the plain soil layer is enhanced, making the entire plastic paving structure more elastic, enabling it to better adapt to ground changes and uneven settlements, improving the anti-deformation ability and overall anti-vibration performance of the plastic paving on the bridge side of the overpass, thereby improving the overall construction quality.

[0057] In this embodiment, in construction step 3), a flexible mesh layer made of elastic material is connected to the top of the bending section. When the gravel layer is formed on the plain soil layer, the flexible mesh layer is laid on the top of the gravel layer;

[0058] In construction step 4), when the concrete layer is formed on the gravel layer, the bottom of the concrete layer is embedded downward into the gravel spaces of the gravel layer, and the flexible mesh layer is embedded in the concrete layer.

[0059] Through the embedding of the flexible mesh layer, the integrity between the gravel layer and the concrete layer is enhanced, reducing the cracking risk caused by temperature changes or traffic loads. In addition, because the load can be more evenly dispersed and local stress concentration is reduced, the durability of the plastic paving is also improved.

[0060] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
