What are the installation conditions of prefabricated running tracks?
Table of Contents
In today's context of increasing requirements for sports venues, prefabricated running tracks have become the first choice for many schools, stadiums and other places due to their excellent performance and convenient installation methods.
However, in order to successfully install a high-quality prefabricated running track, meeting certain installation conditions is the key. Today, let’s talk about the installation conditions of prefabricated running tracks in detail.
Basic ground conditions
Flatness requirements
The flatness of the basic ground is an important prerequisite for the installation of prefabricated running tracks. Ideally, the error of the basic ground should be controlled within ±3 mm for every 3 meters. If the ground flatness is not good, it will cause local unevenness after the prefabricated track is laid, affecting the athlete’s running experience and even increasing the risk of injury. For example, when running on an uneven track, the athlete’s footsteps have uneven points of force, which can easily cause problems such as joint sprains.
Strength and stability
The basic ground must have sufficient strength and stability. Generally speaking, cement concrete or asphalt concrete foundations are more common. The strength grade of cement concrete foundation should not be lower than C20, and its curing time should be sufficient to ensure that the strength meets the requirements. The asphalt concrete foundation should ensure its compaction and flatness to avoid looseness, cracks, etc. Only when the foundation ground is firm and stable can it provide solid support for the prefabricated running track and extend the service life of the track.
Cleanliness
Before installing the prefabricated running track, the foundation ground must be kept clean. There must be no dust, oil, debris, etc., otherwise it will affect the bonding effect between the track and the foundation ground. For example, oil stains will reduce the bonding force between the track and the ground, causing the track to easily bulge and fall off during use. Therefore, the foundation ground needs to be thoroughly cleaned and polished before installation.
Environmental conditions
Temperature conditions
Suitable temperature is crucial for the installation of prefabricated running tracks. Generally speaking, the installation temperature should be controlled between 10℃ and 35℃. Within this temperature range, the bonding performance and physical properties of the track material can be better exerted. If the temperature is too low, the curing speed of the glue will slow down, affecting the installation progress, and the bonding effect will also be affected; if the temperature is too high, the glue may cure too quickly, which is not conducive to the laying and adjustment of the track.
Humidity conditions
Air humidity is also one of the factors that need to be considered. The relative humidity of the air during installation should be maintained between 30% and 80%. If the humidity is too high, the base ground is easily damp, affecting the bonding between the track and the ground; if the humidity is too low, the track material may shrink due to drying and other problems. In addition, it is not suitable to install prefabricated running tracks in rainy and foggy weather conditions with high humidity.
Wind conditions
Excessive wind will also affect the installation of prefabricated running tracks. Generally speaking, the wind force during installation should not exceed level 5. Strong winds will cause the track materials to move during the laying process, affecting the accuracy and quality of the laying, and will also accelerate the volatilization of the glue and reduce the bonding effect.
Construction team and tool conditions
Professional construction team
The installation of prefabricated running tracks requires a professional construction team. Construction workers should have rich installation experience and professional knowledge, and be familiar with the characteristics and installation process of track materials. They can accurately cut, splice and lay the track to ensure the quality and performance of the track. For example, at the joints of the track, professional construction workers can handle the interface well, make it flat and firm, and avoid problems such as cracks.
Appropriate construction tools
The installation of prefabricated running tracks requires appropriate construction tools. Such as tape measures, utility knives, scrapers, rollers, etc. These tools can help construction workers accurately measure and cut track materials, evenly apply glue, and compact the track. For example, rollers can ensure that the track fits tightly with the base ground and improve the stability of the track.
The installation of prefabricated running tracks needs to meet many conditions, from the flatness, strength and cleanliness of the base ground, to the temperature, humidity and wind force of the environment, to professional construction teams and appropriate construction tools. Only when these conditions are met can a high-quality and high-performance prefabricated running track be installed to provide people with a safe and comfortable sports venue.
