Description

Laterite sports field

Technical Field

The utility model relates to an indoor outer stadium field, concretely relates to laterite sports ground.

Background

Tennis court is classified into three types of hard ground (acrylic court such as Mei Net and Australian Net), grassland (e.g., Wen Net), and red court (e.g., French Net). Wherein the advantages of a laterite field are: the tennis ball is low in manufacturing cost, comfortable to exercise, healthy and environment-friendly, and is deeply favored by vast amateur tennis lovers, particularly middle-aged and old people. In the hope of being very popular, tennis courts on sandy soil fields exceed 100 pieces, and tennis lovers playing on sandy soil fields usually account for more than seven people participating in activities.

Although popular, the laterite tennis court has its own disadvantages, such as poor flatness and troublesome routine maintenance, including: sprinkling water, sanding, marking and the like. The most troublesome thing is the marking work, which wastes time and is not easy to mark neatly, and the frequent line sweeping and marking easily causes the unevenness of the wired place on the field, thereby causing the irregular bounce of the ball, greatly influencing the mood of the personnel participating in the activity and simultaneously influencing the popularization and the use of the sandy soil field.

For years, the domestic construction process of the sand tennis court does not have a set of shaping method and standard, and only depends on experience for construction. The traditional method is called construction with three combined soils: the clay-lime-sand concrete is composed of materials such as clay, lime, sand and the like, the combination of the three materials has no fixed proportional relation, and a field constructed by pure clay is also used by experience. These sites have obvious disadvantages after being put into use, such as: the flatness and the hardness of the field do not meet the standard; the white and grey fields are added to be hardened, and the fields without the white and grey fields are soft; the site is sticky and cannot be used after raining or watering; short field service cycle and the like.

The laterite tennis court contact is carried out from nine seven years to four years, the practical construction stage is carried out in 2001, and through years of research and repeated comparison experiments, the laterite tennis court is determined to be made of the following main materials: the red clay tennis court is constructed by selecting red clay, machine-made red sand, red brick powder, industrial raw salt, clear water sand and the like by a machine, and by constructing dozens of red clay tennis court sites such as inner Mongolia Party, inner Mongolian government, inner Mongolian political agreement, inner Mongolian national tax office, Hohao iron road office, Mongolian cow group and the like, abundant experience is accumulated, a whole set of red clay tennis court construction process and a permanent line manufacturing method are successfully mastered, so that the quality of the red clay tennis court is fundamentally improved, the construction by the method not only ensures the court quality, but also greatly prolongs the service life of the red clay tennis court, the maintenance period of the former sandy clay court is generally about three years, and the effective service life of the court is prolonged to more than eight years. Especially, the release of the permanent line of the laterite field thoroughly solves the problems that the sandy soil field is difficult to line and keep the line difficult, thereby fully showing the concept of attractive appearance, practicability, comfort and environmental protection of the laterite tennis field in front of the world population and receiving the high praise reputation of tennis enthusiasts.
