Modular plastic ground and ground foundation

Abstract

The invention provides a modular plastic ground and a ground foundation, comprising a prefabricated coiled material and a foundation; the coiled material includes an arc first coiled material and a linear second coiled material, the foundation is releasably connected with the prefabricated coiled material and includes a plurality of foundation modules, and the foundation modules are hollow, so that the weight of the foundation modules is reduced, transporting is facilitated, manufacturing cost is reduced, and entering the modules for maintenance in later time is facilitated; a drain passage and a leveling device are provided. Modifications are made based on the prior art, the coiled material is designed into the arc first coiled material and the linear second coiled material, applying secondary force to change the shape is not required regardless of straight or bent passages, the coiled materials present uniform freeze-heaving coefficient after being laid, and later deformation rate is low; in addition, the drain passage is arranged in the foundation modules, the foundation has the advantages of construction simplicity, shorter construction cycle, uniform foundation module elasticity and the like, and the structural life of the foundation is prolonged.

Description

technical field [0001] The invention relates to the technical field of sports infrastructure, in particular to a modular plastic field and field foundation applied to runways, football fields, basketball courts, roads and the like. Background technique [0002] Taking the prefabricated plastic runway site and site foundation as an example, prefabricated plastic runways have been used in previous large-scale events such as the Olympic Games and the Athletics World Championships. The paving process has also been used since the 1970s. The layer is well done, and drainage ditches are set on both sides of the base layer, and then artificial runways are laid on the base layer. The prefabricated rubber runway is packaged in the form of coils when it leaves the factory. As people spend more and more leisure time, sports is one of the favorite activities in people's leisure time. Therefore, the scientific and humanized sports facilities are directly related to the personal safety of ...

Problems solved by technology

[0005] b. Bulge: It often appears at the bend. Due to the pulling deformation, the surface tension of the inner and outer rings is inconsistent, and the lateral pressure of the inner ring is too large, resulting in a bulge. The repair method is mostly to use a wedge to remove the excess part of the coil to reduce the horizontal Horizontal pressure, so more gaps are generated, affecting the quality and appearance of the runway, and more likely to cause sports injuries

[0006] Therefore, the method of stretching the curvature of the coil on site is prone to problems such as cracks and bulges. Not only the later repair is laborious and laborious, but also it is easy to cause damage to athletes during exercise.

[0007] 2. The construction of the traditional site foundation is roughly the same as that of the highway roadbed. The steps include: earthwork excavation---plain soil tamping and rolling----backfilling sand and gravel material rolling-----backfilling three-ash soil rolling--- -Backfill cement stabilization layer and roll compaction---concrete surface layer. The above steps have a long construction period, and the foundation is usually realized by using local soil quality and then compacted. After the construction of the artificial runway, for example, when it rains or when the artificial runway is cleaned with water, water, air, and settlement between the base layer and the artificial runway are often caused by the drainage and exhaust of the base layer. Due to inconsistent frost heave coefficients, problems such as frost cracking and other problems occur in the foundation. In severe cases, bubbling occurs, affecting the use of the runway, and even causing damage to the runway. Moreover, the aging problem of the foundation is serious. For example, the cement concrete foundation has been exposed to the sun and rain for a long time. Invasion, etc., prone to weathering and sanding, causing the plastic surface of the runway to delaminate from the foundation, and in severe cases, causing the entire runway to be paralyzed, requiring re-paving and construction, which greatly wastes manpower and material resources
