The EPDM paving construction of plastic runway involves multiple links and steps, which requires a professional construction team and suitable materials to complete.
1. Preparation before construction.
Before construction, adequate preparation is required. First of all, it is necessary to determine the construction site to ensure that the site is flat, dry, free of oil and debris, etc. Secondly, it is necessary to select the appropriate EPDM material to ensure that its quality meets the standard requirements. At the same time, prepare the required construction tools and equipment, such as mixers, laying machines, cutters, etc.
Second, the basic treatment.
Before EPDM laying, the foundation needs to be treated. First, the foundation is cleaned to remove debris and dust from the surface. Then, check the flatness and slope of the foundation to make sure it meets the requirements. If necessary, it can be sanded, filled, etc. Finally, the foundation is waterproofed to prevent moisture from seeping into the runway.
3. Preparation of EPDM materials.
The preparation of EPDM material is an important part of the laying process. First of all, according to the formula ratio provided by the manufacturer, the EPDM particles, catalysts, pigments and other raw materials are mixed. Then, use a blender to blend the ingredients well until no particulate matter is present. The prepared EPDM material should be stored in a dry, ventilated place, away from direct sunlight and moisture.
Fourth, paving construction.
Paving construction is the core link of EPDM paving construction of plastic runway. First of all, according to the design requirements, determine the paving thickness and slope of the runway. Then, the prepared EPDM material is evenly laid on the foundation using a laying machine. During the laying process, it is necessary to pay attention to controlling the laying speed and thickness to ensure that the laying is uniform and free of bubbles and hollowing. At the same time, it is necessary to clean up the debris and waste generated during the laying process in time.
5. Curing treatment.
After the installation is completed, it needs to be cured. In general, EPDM materials require a curing time of more than 24 hours after installation. During the curing period, it is necessary to avoid personnel stepping and heavy objects to avoid affecting the curing effect of the runway. Once curing is complete, further inspection and trimming can be carried out to ensure that the runway surface is flat and smooth.
6. Runway marking.
After the curing of the runway is completed, the runway marking is required. According to the design requirements, use professional marking equipment and pigments to draw the required lines and signs on the runway. During the marking process, it is necessary to pay attention to the clarity and accuracy of the lines to ensure that the athletes can clearly see the signs and lines during the competition and use.
7. Acceptance and maintenance.
After the marking is completed, the EPDM paving construction of the plastic runway is basically completed. Next, acceptance and maintenance work is required. First, a comprehensive inspection of the runway is carried out to ensure that it meets the design requirements and quality standards. If there is any nonconformity, rectification and repair should be carried out in time. Then, carry out regular maintenance and maintenance of the runway, such as cleaning, weeding, repairing, etc., to prolong the service life of the runway and maintain a good use effect.
8. Safety precautions.
In the process of EPDM paving of plastic runway, attention should be paid to safety matters. Construction personnel should wear safety helmets, gloves and other protective equipment to avoid injury. At the same time, it is necessary to comply with the safety regulations and operating procedures of the construction site to ensure the smooth progress of the construction process.
