Steel pipe pile static axial bearing capacity detection device and detection method
The invention relates to a steel pipe pile static axial bearing capacity detection device and detection method. The device comprises an upper steel pipe joint, a lower steel pipe joint and a controllable deformation load box body, wherein the upper steel pipe joint and the lower steel pipe joint have the same specification; the controllable deformation load box body comprises a top plate, a bottomplate and an outer protection tube; the top plate and the bottom plate are of annular structures; the top plate is fixed in the upper steel pipe joint; the bottom plate is fixed in the outer protection tube; the lower part of the outer wall of the outer protection tube is fixed in the lower steel pipe joint; a plurality of first threaded through holes are formed in the top plate; second threadedthrough holes corresponding to the plurality of first threaded through holes are formed in the bottom plate; the first threaded through holes and the corresponding second threaded through holes are connected through locking screw rods; a plurality of jacks are arranged between the top plate and the bottom plate; and the upper ends of the locking screw rods are detachably connected with displacement measuring rods. The steel pipe pile static axial bearing capacity detection device and detection method have the advantages that the bending moment, the shearing force, the pressure and the pullingforce of a pile body during the pile sinking can be effectively resisted; the top plate and the bottom plate are firmly connected and can be easily separated; the displacement measuring rods can be recovered and repeatedly used; and the detection data is accurate and reliable.
本发明涉及一种钢管桩静轴向承载力检测装置及检测方法，其中装置包括上钢管节、下钢管节和可控制变形荷载箱体，上钢管节和下钢管节的规格相同；可控制变形荷载箱体包括顶板、底板和外护筒，顶板和底板为环形结构，顶板固定在上钢管节内，底板固定在外护筒内，外护筒的外壁下部固定在下钢管节内；顶板上设有多个第一螺纹通孔，底板上设有与多个第一螺纹通孔对应的第二螺纹通孔，第一螺纹通孔与对应的第二螺纹通孔之间通过锁紧螺杆连接；顶板和底板之间设有若干千斤顶；锁紧螺杆的上端可拆卸连接有位移测杆。本发明可有效地抵抗沉桩时桩身的弯矩、剪切力、压力和拉力，顶板和底板牢固连接并容易分开，可回收并重复利用位移测杆，检测数据准确可靠。
