Description

Technical Field

[0001] The invention relates to the technical field of sports venues, in particular to a sand pit with a loosening function. Background Art

[0002] As is known, sand pits are often used for long jump training. Since the sand pits are exposed outdoors, long periods of non-use will cause the sand in the sand pits to harden, especially in winter and rainy seasons. Rainwater and snow water enter the sand pits, making them more rigid. Rigid sand pits make it impossible to train, especially in the sand pits in schools. The sand in the sand pits is very hard after each holiday and school starts. Before training, the sand must be loosened before use. If some structures are set on the sand pits to protect them, the sand will fly during training, causing some protective structures to be damaged and affecting their service life.
