Sleeve connecting device for cast-in-situ bored pile construction
The sleeve connecting device comprises a detachable sleeve and a permanent sleeve, an opening groove is formed in the bottom of the detachable sleeve, the inner wall of one side of the opening groove extends inwards to be provided with a positioning groove, the inner wall of the top of the permanent sleeve is fixedly connected with a first internally-connected cylindrical section through welding, and the inner wall of the top of the permanent sleeve is fixedly connected with a second internally-connected cylindrical section through welding. A positioning block is fixed to one side of the first internally-connected cylindrical section in a welded mode, the positioning block and the positioning groove are of a matched structure, the length and the width of the positioning block are the same as those of the positioning groove, and the diameter of the outer wall of the first internally-connected cylindrical section is the same as that of the inner wall of the detachable sleeve. The inner wall of the top of the first internally-connected cylindrical section is fixedly provided with a second internally-connected cylindrical section in a welded mode, the outer wall of the top of the second internally-connected cylindrical section is fixedly provided with an annular sealing edge in a welded mode, the diameter of the outer wall of the annular sealing edge is the same as that of the inner wall of the detachable sleeve, and a notch is formed in one side of the first internally-connected cylindrical section. The invention has the characteristic of no external expansion volume.
本发明公开了一种用于钻孔灌注桩施工的套管接连装置，包括可拆卸套管和永久套管，所述可拆卸套管的底部开设有开口槽，所述开口槽的一侧内壁向内延伸开设有定位槽，所述永久套管的顶部内壁通过焊接固定连接有内接圆柱段一，所述内接圆柱段一的一侧通过焊接固定有定位块，所述定位块与定位槽为配合结构，所述定位块与定位槽的长度和宽度相同，所述内接圆柱段一的外壁直径与可拆卸套管的内壁直径相同，所述内接圆柱段一的顶部内壁通过焊接固定有内接圆柱段二，所述内接圆柱段二的顶部外壁通过焊接固定有环形密封缘，所述环形密封缘的外壁直径与可拆卸套管的内壁直径相同，所述内接圆柱段一的一侧开设有缺口，本发明具有无外扩体积的特点。
