In the course of installation of column, two column center measurement, column spacing is 12.80 meters, the top is 0.914 meters from the ground.
The basic process of tennis court construction:
The first step: planning, site selection.
Before the construction of any project, the first step is to develop a detailed plan. If you want to build a tennis court, before the project is carried out,the first question you must consider is the court should adopt the surface layer? Is the soil surface or modern synthetic plastic surface? Two types have advantages and disadvantages, but the synthetic materials surface in recent years has been improved, its advantage is obvious. The acrylic plastic surface layer has been widely used and recognized.Secondly, it needs to choose the tennis court address, and according to the surrounding environment, planning out the most reasonable construction plan. The main factors are: soil condition, soil layer thickness, groundwater position, the stadium direction, cement or asphalt based selection, multi pitch connected space interval size the construction of the tennis court. According to local conditions, but at least occupy 19 x 37m site.
The second step: foundation construction.
In the future planning and design, to start the foundation construction. The quality level of a tennis court,largely depends on its foundation quality.Therefore, the foundation construction must choose professional construction team building, according to the site requirements, in strict accordance with the construction standards of construction, strict checks site based. Specific requirements are: cement foundation, reinforced concrete foundation. It should be used in commercial concrete laying success once. Join the bar is in order to increase the overall site, to prevent cracking. Every field of the net is below the middle, has to be a contraction joints. The asphalt is based on local ‘s environment,From the ground to dig down the corresponding depth, and then fill the shop of different materials, and gradually make it rolling, the density of not less than 2.35 tons / m3. The asphalt surface should be no pits, no honeycomb, no oil pollution, and ensure the high temperature in the summer when the oil return.
Both the cement foundation and asphalt surface, require the smoothness of the height difference is not greater than 3 mm, which is 3 meters with pressure bar any measurement check on the site, the flatness error average value is less than 3 mm. For outdoor stadium, surface drainage slope of 1:100 to 1:150 (the difference between drainage slope in the ordinary civil engineering do).
In addition, in the foundation construction, be sure to prepare some of the ancillary facilities in advance of avoid leakage,the future will undermine the integrity of the foundation.
The third step: tennis courts, venues around the network, tennis wall, lighting systems and other ancillary facilities
After the basic completion of construction, according to some previous pre buried facilities, backstop and lamppost mounted around the ground, and as far as possible to build a schedule of tennis wall, in order to practice.
The fourth step: laying the ground surface layer
Site based maintenance is completed, other ancillary facilities are properly installed, the surface layer part next to the tennis court to do the key. Although according to different basis, there are a number of different processing methods, and the laying of each product are not the same, but in general, the laying of the surface layer mainly contains the following steps:
1 .clean up and repair base:
Some of the potholes, dent repair, and then cleaning or washing the entire site, note that the repair site must be dry (usually 24 hours) can continue the construction.
2 .adhesive layer:
On the basis of the surface layer need to be coated with a layer of adhesive, it can be closely adhered to the surface of the cement, and the surface of the plastic material closely, but also to prevent the emergence of degumming, peeling and other issues
3 .laying foundation reinforcement layer:
In order to enhance the strength of the site, flatness and service life, the main raw material of plastic surface layer of acrylic acid and quartz sand, water, according to a certain proportion of mixing into a kind of emulsion, evenly laid on the site.
4 .layer filling layer:
By adding acrylic acid based layer material of quartz sand mixing paved, mixed with quartz sand is not only resistant, but also according to the amount of how to control the speed of the ball.
5 .face oil laying:
It is mainly mixed with a certain proportion of water from acrylic acid, and is evenly spread on the filling layer, which has the characteristics of bright color, anti ultraviolet ray fading and certain abrasion resistance.
The fifth step: draw the line, hang the net.
After the face oil laying,it is necessary to carry out the plastic surface at the last step---drawing line.When drawing the line, should pay attention to, must be in strict accordance with the standard size of two small thin pre painted excellent line, and repeatedly check in check. There is no mistake, attached to the two thread the outer side with stickers, and then a special site in them. Then draw a line paintbrush torn stickers, and fit the Internet column, hanging on the net and center pull. So far, through the above five steps, a standard tennis court even finished.
