Professional plastic runway installation process introduction
With the continuous improvement of people's living standards, the demand for fitness consumption is also increasing. Many schools and residential communities are paving on plastic track playgrounds.
The plastic runway is a kind of track that is widely used. It is made of professional materials through professional technology. This plastic runway is in strict accordance with national standards during the production process, and has a high safety factor. The purpose of designing the plastic runway is to prevent athletes from falling and falling when running. The plastic runway uses special materials to ensure that athletes will not fall when falling while running. Because of this feature, the plastic runway is Everywhere, especially schools, because there are many sports in schools, in order to avoid fall injuries, and have good ventilation.
Let Xiao Bian introduce the plastic runway pavement process today:
First, confirm before pavement
1. It is advisable to measure the site size in the field, draw floor plans and pavement maps, and order according to plans to reduce and control losses;
2. Please confirm the specifications, quantity and color of the received goods and the consistency of the order, and check the quantity of the goods on the spot.
3. The arrow at the bottom of the web shows the running direction of the athlete, that is, the orientation of the installation.
4. Please spread the same batch of rolls on the same site to avoid subtle color differences;
5. Adhesives must use special adhesives for this product. Before use, please confirm the fixed ratio and dosage, and use them at the fixed ratio within the specified time;
6. Ensure that the goods and packages are dry (humidity ≤ 10%) and clean before laying, and lay in the specified temperature range (10 °C Celsius ≤ Permissible Temperature ≤ 40 °C Celsius);
7. Must be confirmed by professional measurement technicians in accordance with the design requirements of the track and field mark line, and marked with a strong and clear mark, after the review is correct, can be applied to coil shop;
8. Irregular surface relief is not a product defect.
Second, the preparation
1. Enclosure treatment shall be performed around the site to prevent the miscellaneous personnel and vehicles from entering the construction work surface;
2. Confirm the construction work area to facilitate the entry and exit of goods, storage, and convenience of overlapping of the hydropower facilities;
3. Two-component adhesives need to be separately stored in groups, and set a clear sign of safe ban on fire;
4. The mixing and stirring of the adhesive requires a portable electric mixer and two dry iron drums;
5. The mixed adhesive must be scraped with a special toothed plastic or iron scraper;
6. The special roll holder should be used to move and unwind the coils.
7. The cutting of the coiled material must be done according to the actual site measurement after cutting according to the paving map drawn in advance.
8. The special cutting tool (hand-held grinding wheel or cutting plywood tool) is required for the cutting of the coil.
Third, the basic quality requirements of asphalt
1. Flatness: The foundation should have a certain strength and stability. The base cannot produce cracks and uneven frost heave due to freezing. Flatness pass rate above 95%, 3 meters ruler gauge error within 3mm.
2. Slope: Horizontal
3. Quality of asphalt mixture: use asphalt with low wax content; mix the mixture to the field temperature ≥ 130 °C; compaction temperature ≥ 120 °C, final pressure temperature ≥ 70 °C; roller pressure not less than two times There are no obvious wheel tracks; the density and flatness are measured and adjusted at any time.
4.Strength and stability: The surface is even and solid, smooth without cracks, no lumps, no pockmarks, smooth smooth joints without obvious height difference. The particle size of the fine asphalt concrete surface gravel is 2-5mm, the oil content is 5.8-6.4%, the grindstone size of the coarse asphalt concrete layer is 6-20mm, and the oil content is 4.6%-5.8%. The density of compaction shall not be less than 95%. After medium-sized roller compactor passes, there are no significant wheel marks, no soft peeling, loose loose soil and waves.
5. Drainage: The drainage system must drain water two hours after heavy rain.
6. Curing period: The basic maintenance period is 28 days, reduced during high temperature and rainy season.
Fourth, the paving process introduced
1. Design requirements confirmation
According to the design drawings and the owner's final plan, the design radius and lane width are determined. The recommended radius of conventional 400M track and field is 36.5m, and the lane width is 1.22m.
Determine the field field race and track project configuration.
Determine the design thickness, the thickness of the conventional main track and semicircle is 13mm, the thickness of the thickened area is 20mm, and the thickness of the obstacle pool area is 25mm.
