Sleeve for elastic clamping type connection of prestressed concrete square pile and preparation method of sleeve
The invention provides a sleeve for elastic clamping type connection of a prestressed concrete square pile and a preparation method of the sleeve. The sleeve for connecting the prestressed concrete square pile in the elastic clamping mode comprises a sleeve body, a groove is formed in the top of the sleeve body, a through hole is formed in the inner wall of the bottom of the groove, and the preparation method of the sleeve for connecting the prestressed concrete square pile in the elastic clamping mode comprises the following steps that S1, material cutting is conducted; s2, ball pressing; s3, performing shaping; s4, stretching; s5, edge pressing; and S6, punching small holes. The sleeve for elastic clamping type connection of the prestressed concrete square pile and the preparation method of the sleeve have the advantages that the process is relatively simple, and the prepared sleeve is high in strength.
本发明提供一种弹卡式连接预应力混凝土方桩用套筒及其制备方法。所述弹卡式连接预应力混凝土方桩用套筒包括筒体，所述筒体的顶部设有凹槽，所述凹槽的底部内壁上开设有通孔，所述弹卡式连接预应力混凝土方桩用套筒的制备方法，包括以下步骤：S1：切料；S2：压球；S3：正形；S4：拉伸；S5：压边；S6：冲小孔。本发明提供的弹卡式连接预应力混凝土方桩用套筒及其制备方法具有工艺相对简单、制备出的套筒强度较高的优点。
