Description
Technical Field
The utility model relates to a natural lawn structure in football place specifically is a natural lawn structure is planted to compound bionical soil bed.
Background
Since the 70's of the last century, artificial grass was introduced into the football world, and large-scale disputes were raised in the international sports world, so far, the maturity of natural grass and artificial grass still plays a minor dispute in the sports world. Until the mid-80 s, the international standards for sports field turf sport quality evaluation were both issued by the international standards for foot (FIFA) and the british national sports committee, which made the debate of the two practical objective criteria. The main effects of artificial and natural grass on soccer include:
1. the impact of two field elasticities on soccer:
the natural grass plant fiber elasticity of the natural lawn football field is limited, so that the elasticity of the football on the natural lawn is small, the height of the high-altitude ball or the bounce ball bounced after falling to the ground is not very high, and the football is convenient for players to receive, stop and control the ball. However, the artificial grass in the artificial turf football field is made of plastic fibers, so that the artificial turf football field is determined to have good elasticity, and the force of the football flying from high altitude or in half-air, which is rebounded when falling on the football field, is also large.
2. The effect of two field friction forces on soccer:
the friction force of plant grass fibers of the natural lawn football field to the football is not large, so that the football is determined to roll on the natural lawn at a high speed and at a long distance. However, the friction force of the chemical fiber grass on the football is large in the artificial turf football field, the ball falls on the artificial turf and is difficult to feel, the rolling speed is slow, and the rolling distance is relatively short.
3. The effect of two field soccer fields on player's joint damage:
when people watch live broadcasting in a competition, the picture that the whole natural turf is lifted off under violent confrontation can be often seen, the turf is considered to be weak, the root of the turf and even the taking off of the turf together with soil substantially protect all joint parts, and on the artificial turf, colloidal particles are pushed away, so that all joints and ligaments bear higher stress in the violent actions, and the artificial turf is naturally easy to pull and damage.
The flatness of natural turf is difficult to compare favorably with that of artificial turf, and joint damage is easily caused due to depressions on the ground; on the other hand, kicking a ball on a natural lawn can cause a player to generate an impulse which makes a difficult action, such as a sliding shovel, an inverted hook and the like, and actually can increase the probability of injury.
4. The influence of the drainage function of two kinds of place football court to football:
drainage systems are the most important foundation for lawns in football fields. The drainage problem is first considered in the construction of a soccer field. The drainage system of the artificial lawn comprises overground drainage and underground drainage, the overground drainage is generally drained through a certain gradient (0.2% -0.5%), and the field can be set to be high in the middle and low around so as to be beneficial to draining accumulated water. In addition, sandy loam which has good water permeability and is beneficial to water permeability is selected. However, the football field which is more advanced is provided with an underground drainage system because the ground drainage is only relied on and is slower. Underground drainage systems are typically designed with drainage pipes in the foundation. The drain pipe is generally made of tile pipes, concrete pipes and other materials. There are many kinds of layout, and different layout densities are designed according to different rainfalls. When water accumulates in the court, water permeates into the bottom of the foundation layer from the lawn cushion layer of the permeation grate and is collected to the main pipe by the drainage branch pipe to flow out of the court; the drainage system of natural turf is substantially identical to that of artificial turf.
The artificial grass has the advantages that the artificial grass has many advantages that natural grass cannot be compared with natural grass, as is well known, the artificial grass needs to be maintained for two days in a match with a natural grass kicking, the artificial grass can be used in all seasons and all weather for 24 hours without interruption, and the later maintenance cost is basically lower.
Thus, the FIFA certified artificial grass has three indicators: the durability of the grass surface, the motor response of the football on the surface, and the motor response of the players on the surface. The indexes are detected in a laboratory and in the field respectively, the indexes are selected to be that the data of the artificial turf is expected to be closer to the data of the natural turf, and the excellent artificial turf can be very close to the motion indexes such as shock absorption, ball rebound and rolling, steering values and the like. However, the manufacturing costs of an artificial lawn are also high if the artificial lawn can meet the FIFA standard.
In view of the above, the natural artificial mixed system lawn has come to the end, and the natural artificial mixed system lawn combines the natural lawn and the artificial lawn, and is developed by making up for the deficiencies of the natural lawn, and the natural artificial mixed system lawn not only has the advantages of trampling resistance and wear resistance of the artificial lawn, but also has the speciality and safety of the natural lawn so as to meet the use requirements of sports fields.
At present, natural and artificial mixed lawns have two methods:
1. implanted InSitu implanted mixing system
The implanted mixed system lawn is prepared by implanting artificial Polypropylene (PP) filament of 20cm length into the surface of the ground by computer-controlled machine, wherein 18cm of artificial filament is buried underground, 2cm of artificial filament is exposed out of the ground, and the implantation density is 2 × 2 cm. The implantation operation can be carried out before sowing, after lawn formation or on turf blocks.
The implanted hybrid system lawn is also called a permanent hybrid system lawn, and the hybrid system lawn cannot be moved, disassembled and replaced after being finished, and cannot be cultivated in a lawn base and cannot be rolled up in advance. Because of using large-scale implantation machine, the construction cycle is long, the cost of restoration is high. The artificial grass filaments have low density, generally about 1000-.
2. Carpet type Carpet
The grass blanket type natural artificial mixed system lawn is characterized in that an artificial grass blanket is laid on a root system layer, artificial grass filaments are combed and erected after sand and other polymer substances are filled in the artificial grass blanket and then sowed, and a natural grass root system penetrates through the bottom of the grass blanket and keeps the system stable. The field can be constructed and sowed on site, and can also be moved into the field after being planted in advance in a lawn base.
Depending on the type of artificial grass carpet used, a woven hybrid system lawn and a tufted hybrid system lawn are classified.
Weaving type artificial lawn: the weaving type artificial grass is characterized in that warp yarns are arranged on a warp beam of a weaving machine, weft yarns are arranged on the weaving machine along the direction vertical to the warp yarns, artificial grass silk yarns are arranged on a creel behind the weaving machine and are woven into a base fabric, the artificial grass silk yarns participate in the weaving of the base fabric along the warp yarns in a parallel mode, and jacquard weaving treatment is carried out on the artificial grass silk yarns by using jacquard equipment of the weaving machine; each artificial grass yarn is raised out after 2-10 weeks of winding in the base fabric to form a cluster of grass yarns, and 6-12 warp yarns are arranged between any two adjacent grass yarn clusters; 3-8 weft yarns are arranged between any adjacent 2 grass silk tufts in the vertically arranged grass silk tufts.
Tufted hybrid system lawn: the tufting type artificial grass is that artificial grass filaments are tufted on a base cloth by knitting; then, coating the latex on the back of the base cloth, and uniformly spreading the latex by using a scraper to completely cover the base cloth; the second mode is that the glue-coated fence plate is evenly coated on the base cloth at the root of each bundle of grass filaments, and after cooling and solidification, a spaced-type back glue layer is formed, and the artificial turf is obtained. The artificial grass filaments are made of polyethylene materials, and the base cloth is made of polypropylene materials; the base cloth is single-layer PP base cloth, double-layer PP base cloth or single-layer PP base cloth and grid cloth. The glue barrier panel spacing can be adjusted to be 3/4, 5/8, 1/2, 3/16 equidistant parallel hollowed out panels. The latex is carboxylic styrene-butadiene latex or polyurethane latex. The glued fence board is made of one of similar materials such as steel, aluminum alloy, polytetrafluoroethylene and the like. The artificial grass filaments have low extraction force and poor reinforcing effect; the base cloth is provided with the back adhesive, so that the environment is not completely protected; the artificial grass filaments are lodged and have poor greening effect.
The obvious disadvantages of the natural and artificial mixed lawns are:
when the natural grass is dormant, the football field is still the use effect of the artificial lawn, and the inherent defects of the artificial lawn exist; moreover, the reseeding and variety replacement of natural grass seeds cannot be realized.
On the basis of artificial grass woven fabric, natural grass is planted by enlarging the porosity of the fabric, the construction requirement is harsh, the process is complex, and the manufacturing cost is high, so that a few acceptable customers prove that the lawn is not a popular lawn.
