[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0021] In order to enable those skilled in the art to better understand the device of the present invention, the present invention is described in detail below using the Yajiang County Hongxing "1+N" project, Section I, 500MW photovoltaic power station as an example:

[0022] Use Portland cement with a strength grade of no less than 42.5 or 52.5. Use hard, durable, and clean crushed stone as the coarse aggregate, with a maximum nominal particle size no larger than 26.5 mm. Use hard, clean sand with a fineness modulus of 2.5 or greater as the fine aggregate. Use removable wooden formwork (coated with an environmentally friendly release agent) to create a 26 cm thick concrete pavement.

[0023] like Figure 1 As shown, a pavement based on bamboo reinforced concrete and a construction method thereof include the following steps:

[0024] Step 1. Prepare an appropriate amount of 4-5 year old bamboo, process it into bamboo strips with a width of 2.5 cm, a thickness of 0.8-1.0 cm, a horizontal length of 152.5 cm, and a vertical length of 450 cm. Then tie the bamboo strips into a bamboo reinforcement net with a length of 4.5 meters and a width of 1.525 meters. Use wire or other materials to tie the vertical and horizontal joints of the bamboo reinforcement firmly to prevent looseness. Prepare concrete, coarse and fine aggregates, and concrete additives suitable for the local climate and load requirements.

[0025] Admixtures should be selected that meet national standards, and the dosage should be determined based on testing. Jointing materials should be expansion joint plates that can adapt to the expansion and contraction of the concrete panel, remain stable during construction, have a high elastic recovery rate, and exhibit excellent durability. Joint filling materials should exhibit strong adhesion to the concrete slab wall, exhibit good resilience, be insoluble in water, and be impermeable.

[0026] Step 2. Mix the concrete, erect the formwork on the qualified roadbed, and apply environmentally friendly release agent;

[0027] The concrete mix ratio is determined through experiments to ensure that the concrete has good workability, strength and durability. The mix ratio design should take into account the influence of factors such as cement type, aggregate type and gradation, and admixtures on the performance of concrete.

[0028] Removable wooden formwork (coated with environmentally friendly release agent), single piece length 2m, thickness and pavement shape strictly determined according to the test research plan, and joints sealed.

[0029] Step 3. Fix the bamboo mesh at the middle height of the mold;

[0030] like Figure 2 and Figure 3 The bamboo reinforcement mesh is placed in the center of the pavement, 13 cm from the bottom, with the horizontal reinforcement at the bottom and the vertical reinforcement at the top, with all the green bamboo facing down and the yellow bamboo facing up. When pouring the concrete pavement, steel support or mortar pads are used to fix the bamboo reinforcement mesh.

[0031] Step 4. Concrete pouring;

[0032] The embodiment adopts manual paving with a thickness of 260mm. The thickness and paving quality of the concrete should be checked at any time during the paving process, and problems should be dealt with in time. After the concrete is paved, it should be vibrated immediately. Use a vibrating rod for vibration, and the vibration time should be determined according to the slump of the concrete and the performance of the vibrating equipment, generally 15-30 seconds. Avoid over-vibration or missed vibration during vibration to ensure that the concrete is dense. The concrete surface after vibration should be leveled, and a vibrating beam or a trowel can be used for leveling. The flatness and cross slope of the concrete surface should be controlled during leveling to make the pavement surface flat and smooth, and the drainage slope meets the requirements. After the concrete surface is leveled, it should be roughened or embossed to increase the anti-skid performance of the pavement. The depth of roughening or embossing is generally 1 to 2 mm, and the texture should be clear and uniform.

[0033] Step 5. Concrete curing.

[0034] After concrete pavement construction is completed, curing should be carried out promptly. This can be done by sprinkling water, covering, or spraying curing agents. Curing generally takes 7 to 14 days. During this period, the concrete surface should be kept moist and protected from direct sunlight, wind, and rain.

[0035] The results are as attached Figure 3 As shown, this device has a good effect.

[0036] Finally, it should be noted that the above embodiments are merely preferred embodiments of the present invention and are used to illustrate the device of the present invention, rather than limiting it, and certainly not limiting the patent scope of the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the width of the device described in the aforementioned embodiments can still be modified, or some of the dimensions thereof can be adjusted. These modifications do not deviate the essence of the corresponding device from the scope of the device of the embodiment of the present invention. In other words, any changes or modifications that are made to the main design concept and spirit of the present invention without any substantive meaning, as long as the technical problems they solve are still consistent with the present invention, should be included in the protection scope of the present invention. In addition, the direct or indirect application of the device of the present invention in other related technical fields should also be included in the patent protection scope of the present invention.
