Large-diameter circular rectangular secant pile connecting system and construction technology
The invention discloses a large-diameter circular-rectangular secant pile connecting system and a construction technology, the system comprises circular secant piles, rectangular secant piles and T-shaped joints, the circular secant piles and the rectangular secant piles alternately form the circular-rectangular secant piles, slotted holes are milled at the joints for mounting the T-shaped joints, the joints comprise first joints and second joints, and the first joints and the second joints are connected through bolts. A first connecting rib is arranged on the reinforcement cage of the first connector, a second connecting rib is arranged on the reinforcement cage of the second connector, a C-shaped connector is welded to the end of the first connecting rib, a C-shaped opening of the connector faces the second connecting rib, and a locking head is welded to the end of the second connecting rib. The C-shaped connector sleeves the outer side of the second connecting rib to form a fastened anti-pulling structure, the C-shaped connector and the second connecting rib are put down, then concrete is poured, the C-shaped connector and the second connecting rib are both embedded and fixed into the secant pile to form a permanent rigid structure, and the connecting strength of the circular secant pile and the rectangular secant pile is improved; the problems that the connecting position of the circular-rectangular secant piles is insufficient in tensile capacity, and a connector is prone to cracking due to tension are solved.
本发明公开了一种大直径圆矩咬合桩连接系统及施工工艺，该系统包括圆咬合桩、矩咬合桩和T型接头，圆咬合桩和矩咬合桩交替形成圆‑矩咬合桩，在连接处铣出槽孔用于安装T型接头，该接头包括第一接头和第二接头，且在第一接头的钢筋笼上设置第一连接筋，第二接头的钢筋笼上设置第二连接筋，第一连接筋的端头焊接设有C形态接口，该接口呈C型开口朝向第二连接筋，第二连接筋的端头焊接设有锁定头，C形态接口套在第二连接筋外侧后形成紧固的防拉结构，将两者下放再浇筑混凝土，使两者都嵌入固定于咬合桩内形成永久性的刚性结构，提高圆咬合桩和矩咬合桩的连接强度，解决了圆‑矩咬合桩连接处抗拉能力不足和连接头容易受拉开裂的问题。
