Description

Rigid foundation polyurethane plastic runway

Technical field

The utility model relates to runway, relates in particular to rigid foundation polyurethane plastic runway.

Background technology

Plastic cement race track be have certain flexible.When the strength ratio of sportsman in motion process is larger; tend to ankle to cause unexpected injury; on sports ground, if plastic floor, because its raw material is so hard unlike raw materials such as cement, itself just has certain spring function; so in motion process; the resilient characteristic of plastic floor will be given invisible bounce of athletic ankle, thereby can alleviate the injury to health, and effectively protection motion is healthy; therefore, plastic cement race track is widely used in each sports ground.

Yet, existing plastic cement race track, generally on original soil rammed layer, laying mixed earth, as foundation, then is laid plastic coat on basis, the plastic cement race track of this structure, to poor, easily there is the problems such as local dent, simultaneously in its rigid phase, do not do tight waterproofing work, therefore, its waterproof effect is poor, in addition, the plastic layer of tradition runway is that surface layer adds bottom double-decker, its poor flexibility, is used a period of time, and surface is aging gradually, flexibility decrease, the comfortableness of motion reduces, and the stressed increase in sportsman foot joint, easily causes damage etc.

The beneficial effects of the utility model are: the rigid foundation polyurethane plastic runway that the utility model provides, its basis adopts lays successively hardcore bed and cement stone dust stabilized zone on original soil rammed layer, on cement stone dust stabilized zone, lay steel concrete again, so, its basic rigidity is higher, structure is more firm, simultaneously, between reinforced concrete floor and cement stone dust stabilized zone, lay a PVC waterproofing membrane layer, between reinforced concrete floor and plastic layer, lay a waterproof reinforced layer, so, the water resistance of whole plastic cement race track improves greatly, guarantee the dry and comfortable state of the long-term maintenance of plastic layer, long service life, be difficult for aging, in addition, plastic layer adopts the lamination layer structure of polyurethane adhesive grain layer, elastic polyurethane bubble layer and black particle bottom, in traditional structure, set up elastic polyurethane bubble layer, to strengthen the elasticity of plastic cement race track, its elasticity is better than traditional runway, reduce sportsman foot joint stressed, the sportsman foot joint that adequately protected, has guaranteed the comfortableness of moving.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model embodiment;

In figure: polyurethane adhesive grain layer 10; Elastic polyurethane bubble layer 11; Black particle bottom 12; Waterproof reinforced layer 20; Reinforced concrete floor 30; PVC waterproofing membrane layer 40; Cement stone dust stabilized zone 50; Hardcore bed 60; Original soil rammed layer 70.

The realization of the utility model object, functional characteristics and advantage, in connection with embodiment, are described further with reference to accompanying drawing.

The specific embodiment

Below with reference to drawings and the specific embodiments, describe the technical solution of the utility model in detail, so as clearer, understand invention essence of the present utility model intuitively.

Shown in Fig. 1, the utility model provides a kind of rigid foundation polyurethane plastic runway, when guaranteeing rigidity, have good elasticity and water resistance, this runway comprises plastic layer, waterproof reinforced layer 20, reinforced concrete floor 30, PVC waterproofing membrane layer 40, cement stone dust stabilized zone 50 and hardcore bed 60 from top to bottom successively.

Because adopting, basis on original soil rammed layer 70, lays successively hardcore bed 60 and cement stone dust stabilized zone 50, on cement stone dust stabilized zone 50, lay steel concrete again, so the rigidity on basis is higher, structure is more firm, guarantee plain being laid on basis of plastic layer, time is used, and there will not be the problems such as plastic cement race track surface depression.Simultaneously, in order to improve water resistance, between reinforced concrete floor 30 and cement stone dust stabilized zone 50, lay a PVC waterproofing membrane layer 40, between reinforced concrete floor 30 and plastic layer, lay a waterproof reinforced layer 20, so double layer water-proof structure design, can make the water resistance of whole plastic cement race track greatly improve, and guarantees the dry and comfortable state of the long-term maintenance of plastic layer, long service life, is difficult for aging.
