The invention belongs to a self-closing grouting sleeve structure for constructional engineering in the technical field of constructional engineering, and further relates to a self-closing grouting method for constructional engineering. A grout outlet hole (1) is formed in a sleeve body (7) of the self-closing grouting sleeve structure for the constructional engineering, a sliding piston (3) and a fixed piston (6) are arranged in the grout outlet hole (1), a sliding rod (5) is connected to the sliding piston (3) and movably penetrates through the fixed piston (6), and a plurality of one-way springback spring pieces (4) are arranged on the inner wall of the sleeve body (7) and extend towards the fixed piston (6). According to the constructional engineering self-closed grouting sleeve structure and the constructional engineering self-closed grouting method, the grout leakage phenomenon of the grout outlet hole of the grouting sleeve in the existing grouting process can be effectively avoided, so that grout leakage of the grout outlet hole is effectively prevented, and the grouting compactness and the grouting efficiency are improved.

本发明属于建筑工程技术领域的建筑工程自闭式灌浆套筒结构，本发明还涉及一种建筑工程自闭式灌浆方法。所述的建筑工程自闭式灌浆套筒结构的套筒本体(7)设置出桨孔(1)，出桨孔(1)内设置滑动活塞(3)和固定活塞(6)，滑动活塞(3)上连接滑动杆(5)，滑动杆(5)活动穿过固定活塞(6)，套筒本体(1)内壁设置多个单向回弹弹簧片(4)，单向回弹弹簧片(4)向固定活塞(6)方向延伸。本发明所述的建筑工程自闭式灌浆套筒结构及建筑工程自闭式灌浆方法，能够有效解决现有灌浆过程中灌浆套筒出浆孔漏浆现象，从而有效防止出浆孔漏浆、提高灌浆密实度和灌浆效率。
