Post-grouting device for inside and outside of pile end of tubular pile
The invention relates to the technical field of precast pile foundations, solves the problem that the prior art is greatly influenced by the welding technology, and discloses a tubular pile end inside and outside post-grouting device which comprises a first connecting layer, a second connecting layer, a closed ring piece and a plurality of grouting pipes. The first connecting layer is connected with the pile end; the second connecting layer is connected with the pipe pile; the opposite ends of the first connecting layer and the second connecting layer are provided with a first butt joint column and a second butt joint column respectively. The first butt joint column is connected with the second butt joint column; the closed ring sheet is detachably connected with the first connecting layer and the second connecting layer; a pouring space is reserved between the inner wall of the closed ring piece and the outer walls of the second butt joint column and the first butt joint column. The multiple grouting pipes penetrate through the first connecting layer and the second connecting layer in the length direction of the pipe pile. The grouting pipe comprises a pipe body and a plurality of pipe joints; the plurality of pipe joints are coaxially arranged at intervals; the pipe body is a continuous pipeline and coaxially penetrates through the multiple pipe joints. The sealing performance of the pipe pile in the sinking process can be ensured, and the uncertainty of the welding technology is reduced.
本申请涉及预制桩基的技术领域，改善了现有技术受到焊接技术影响较大的问题，公开了一种管桩桩端内外后注浆装置，其包括第一连接层、第二连接层、封闭环片和若干注浆管；第一连接层连接桩端，第二连接层连接管桩；第一连接层和第二连接层相对的一端分别设置有第一对接柱和第二对接柱；第一对接柱和第二对接柱相连接；封闭环片可拆解连接第一连接层和第二连接层；封闭环片的内壁与第二对接柱和第一对接柱的外壁之间留有浇筑空间；若干注浆管沿管桩长度方向贯穿第一连接层和第二连接层；注浆管包括管体和若干管节；若干管节同轴间隔设置；管体为连续管道，管体同轴贯穿若干管节。本申请能够确保管桩下沉过程中的密封性，减少焊接技术的不确定性。
