Ultra-long double-pile-casing structure for uplift test pile detection and using method thereof
The invention discloses a super-long double-pile-casing structure for uplift test pile detection and a using method of the super-long double-pile-casing structure, and belongs to the technical field of test pile detection. The device comprises a first segment and a second segment connected with the first segment. The first section comprises a lower section inner pile casing and a lower section outer pile casing. The outer wall of the lower-section inner pile casing is connected with the upper end of the lower-section outer pile casing through a first temporary fixing device; the lower-section inner pile casing is connected with the connecting piece; the lower end of the lower-section outer pile casing is connected with the supporting table; the supporting table and the connecting piece are in sealed connection through an annular gasket. The lower section outer pile casing is sleeved with a connecting pile casing; the second section comprises an upper section inner pile casing and an upper section outer pile casing; the upper end of the upper-section inner pile casing is connected with the upper end of the upper-section outer pile casing; and the lower end of the upper-section outer pile casing is connected with the outer wall of the upper-section inner pile casing through a second temporary fixing device. The construction difficulty can be reduced, precise installation of the double pile casings and concentricity of the inner pile casing and the outer pile casing in the field splicing process of the double pile casings can be achieved, testing of the pull-out test pile can be achieved, and the test result is accurate and efficient.
本发明公开了一种用于抗拔试验桩检测的超长双护筒结构及其使用方法，属于试验桩检测的技术领域。本发明包括分节一和与其连接的分节二；分节一包括下节内护筒和下节外护筒；下节内护筒外壁和下节外护筒上端通过第一临时固定装置连接；下节内护筒与连接件连接；下节外护筒下端与支撑台连接；支撑台与连接件之间通过环形垫片密封连接；下节外护筒外套有连接护筒；分节二包括上节内护筒和上节外护筒；上节内护筒上端和上节外护筒上端连接；所述上节外护筒下端与上节内护筒外壁通过第二临时固定装置连接。本发明既能够减少施工难度，实现双护筒精准安装、双护筒现场拼接过程中内外护筒同心，又能够实现抗拔试验桩的测试，且试验结果准确高效。
