Abstract
An annular shaped-charge and blasting housing and a use method thereof are provided. The annular shaped-charge and blasting housing includes a PVC segment and multiple notch grooves. Grooves are notched on a W-shaped PVC segment formed by machining. The notching angle of the groove and the spacing distance between the grooves can be adjusted according to use requirements. And, the W-shaped PVC segment after being cut may not be limited to have eight notch grooves, and the number of the notch grooves of a single one PVC segment can be adjusted according to actual working conditions. The PVC segment can be folded and closed to form the annular shaped-charge and blasting housing. Therefore, the housing of the embodiments is simple in production, the linear segment can be bended and folded by utilizing the plasticity of the PVC material. The manufacturing process of the housing is simple and feasible. The housing of the embodiments is convenient to use and can meet the requirements of the annular shaped-charge cutting in blasting engineering. Meanwhile, the housing of the embodiments are widely applied. Further, the housing is not only applicable to annular shaped-charge cutting for th…
