Corrugated pipe for high-density polyethylene prestressed concrete and preparation method of corrugated pipe
The invention relates to a corrugated pipe for high-density polyethylene prestressed concrete and a preparation method of the corrugated pipe. The corrugated pipe comprises a plastic inner pipe, a plastic plate strip spirally wound and fixed on the plastic inner pipe, a pair of lap joint strips, a V-shaped buffer strip spirally wound on the plastic plate strip, a steel strip wrapped outside the buffer strip, and a corrugated strip wrapped outside the plastic plate strip and the steel strip. The preparation method comprises the following steps that firstly, the prefabricated product B is spirally wound on the prefabricated product A, an opening of the buffer strip faces the lap joint strip, then the outer side surfaces of the plastic plate strip and the wrapping strip are coated with bonding resin, and the corrugated pipe is obtained. According to the corrugated pipe, the influence of vibration on the corrugated pipe can be effectively reduced, so that the corrugated pipe has impact resistance and compression strength; in addition, according to the method, the stability of the corrugated pipe structure can be improved while the machining steps are reduced, and therefore the impact resistance of the corrugated pipe can be guaranteed.
本发明涉及一种高密度聚乙烯预应力混凝土用波纹管及其制备方法，波纹管包括塑料内管、螺旋缠绕固定于所述塑料内管上的塑料板带、一对搭接带、螺旋缠绕于所述塑料板带上的V字形的缓冲带、包裹于所述缓冲带外的钢带、包覆于所述塑料板带和钢带外的波纹带；制备方法包括以下步骤，先将预制品B螺旋缠绕于预制品A上，并使缓冲带的开口朝向搭接带，再用粘结树脂涂覆于塑料板带和包覆带的外侧表面，得到波纹管。本发明的波纹管能有效减小震动对其的影响，使波纹管具有抗冲击性能和耐压强度；另外，本发明的方法在减少加工步骤的同时，能提高波纹管结构的稳定性，从而能保证波纹管抗冲击性能。
