Temperature requirements for the construction of plastic runwaysPlastic track is a widely used sports ground layer, and its construction quality has an important impact on the performance and safety of athletes. In the construction process, temperature is an important influencing factor and plays a vital role in the quality of construction. This article will introduce the construction temperature requirements of plastic runways in detail to help construction personnel better control the construction quality.
1. The influence of temperature on the construction of plastic runway.
Temperature is one of the key factors affecting the construction quality of plastic runways. In a high-temperature environment, plastic materials are prone to deformation and flow, resulting in a decrease in material performance and affecting the construction effect. In the low temperature environment, the elasticity of the plastic material will deteriorate, the hardening speed will be slowed down, and it is easy to produce cracks and other problems. Therefore, choosing the right construction temperature is an important prerequisite to ensure the quality of construction.
Second, the construction temperature requirements of the plastic runway.
According to practical experience, the suitable temperature range for plastic runway construction is generally between 15 and 30. In this temperature range, the performance of plastic materials is relatively stable, which can ensure the construction quality. Specifically, the following points need to be paid attention to during the construction process:
1.Basic temperature control.
During the construction process, it is necessary to ensure that the base temperature is within a certain range. In general, the basal temperature should be above 15 to ensure that the speed of foundation hardening and drying meets the requirements. If the base temperature is too low, the temperature can be increased by adding heating equipment.
2.Material temperature control.
Plastic materials should also be controlled by temperature during transportation and storage. Make sure that the temperature of the material is not lower than 15 to avoid the material becoming hard and brittle. At the same time, before the material is mixed, each component material should be preheated to a suitable temperature to ensure the stable performance of the material after mixing.
3.Construction environment temperature.
During the construction process, it is necessary to pay attention to the changes in the ambient temperature and try to avoid construction in extreme temperatures. If you encounter weather changes such as sudden cooling, you should take timely measures such as increasing insulation materials to keep the temperature of the construction environment stable. At the same time, during construction, direct sunlight and other conditions that affect the base temperature should be avoided.
4.Hardening time vs. temperature.
The hardening rate of plastic runway material is closely related to temperature. In the appropriate temperature range, the hardening time decreases as the temperature increases. Therefore, the hardening time should be adjusted according to the actual situation during the construction process to ensure the performance and life of the runway.
5.Temperature monitoring and recording.
During the construction process, the construction environment temperature and base temperature should be monitored and recorded regularly. This helps to find and solve the construction quality problems caused by temperature problems in time, and at the same time provides reference and basis for subsequent construction.
3. Measures to cope with temperature changes.
In order to cope with the impact of temperature changes on the construction of plastic runways, the following measures can be taken:
1.Choose the right base material: Choose the right base material according to the local climatic conditions and construction season to resist problems such as deformation and cracks at different temperatures.
2.Use the right additives: During the construction process, some additives can be used to improve the properties of plastic materials. For example, plasticizers can be used in high-temperature environments to improve the flexibility and durability of materials; Cold resistants can be used at low temperatures to improve the elasticity and hardening rate of the material.
3.Strengthen construction monitoring: In the construction process, monitoring should be strengthened, and construction quality problems caused by temperature changes should be found and solved in a timely manner. For example, if the basal temperature is found to be too low or too high, measures should be taken to adjust it in time; If the material properties are found to be unstable, the material should be replaced or the formula adjusted in time.
4.Training of construction personnel: Training of construction personnel of plastic runways to improve their understanding of the impact of environmental factors such as temperature on construction quality. At the same time, construction personnel should be regularly assessed and evaluated to ensure that they have qualified skills and qualities.
5.Establish a quality management system: Establish a sound quality management system and clarify the quality requirements and standards for the construction of plastic runways. At the same time, the construction quality should be regularly inspected and evaluated to ensure that the construction quality meets the requirements and continues to improve.
