Abstract

The invention and innovation provide a prestress protection device which comprises three to five protection units. Each protection unit comprises a prestress anchor rod (1), a prestress reinforcement (2) and an arc-shaped protection structure (3), one end of each prestress anchor rod (1) is heated, headed and pressed to be in a square cap shape, and is welded to one end of the corresponding prestress reinforcement (2), circular rings are welded to the other ends of the prestress reinforcements (2), and the arc-shaped protection structures (3) penetrate through the circular rings, and are movably connected with the prestress reinforcements (2) through the circular rings. The arc-shaped protection structures (3) of the three to five protection units are connected together to form the complete prestress protection device. Due to the technical scheme, newly-planted new saplings or infirm old saplings can be effectively fixed through the prestress protection device and can be effectively prevented from being pulled up by the roots or broken off in the severe weather of rainstorm and the like, and environment is maintained better.

Description

technical field [0001] The invention specifically relates to a prestressed protective appliance. Background technique [0002] With the rapid development of the global economy, environmental pollution has become more and more serious. People have gradually realized this problem and started extensive afforestation to save the damaged environment. However, many small saplings that have just been implanted in the soil are broken by violent wind and rain when experiencing harsh wind and rain, and even uprooted seriously, which brings great difficulties to people's afforestation work and is not conducive to effective prevent environmental degradation. Contents of the invention [0003] The purpose of the invention is to provide a prestressed protection tool for afforestation with simple structure and practicality. [0004] The technical solution created by the present invention is: a prestressed protective appliance, including 3-5 protective units, and a protective unit inclu...
