WAN XINWEI

The invention discloses a soft foundation structure of a playground lawn and a construction method thereof.The soft foundation structure comprises drainage blind pipes, a punning layer, a rubble layer, a granite layer, a plastic permeable soft base layer and a lawn layer, the punning layer is located at the bottommost end, the lower surface of the rubble layer makes contact with the upper surface of the punning layer, and the drainage blind pipes are arranged in the rubble layer; the lower surface of the granite layer is in contact with the upper surface of the gravel layer, the lower surface of the plastic permeable soft base layer is in contact with the upper surface of the granite layer, and the lower surface of the lawn layer is in contact with the upper surface of the plastic permeable soft base layer. The construction method is simple, the built soft foundation has the hardness more suitable for human body movement and is more environment-friendly, the site water seepage rate can be increased, an artificial lawn and a natural lawn can be freely switched, the project cost is reduced to a certain degree, and the construction method is suitable for football fields, baseball fields, softball fields, rugby fields, battlefield fields, golf fields and other playgrounds.

本发明公开了一种运动场草坪的软基础结构及其施工方法，包括排水盲管、夯实层、碎石层、米石层、可塑透水软基层和草坪层，夯实层位于最底端，碎石层的下表面与夯实层的上表面接触并且多根排水盲管设置在碎石层中，米石层的下表面与碎石层的上表面接触，可塑透水软基层的下表面与米石层的上表面接触，草坪层下表面与可塑透水软基层的上表面接触。本发明施工方法简单，建成的软基础有更适合人体运动的硬度，更加环保，又可以加快场地渗水速率，可以让人造草坪和天然草坪自由切换，在一定程度上减少项目成本，适用于足球场、棒球场、垒球场、橄榄球场、板球场、高尔夫球场等运动场。
