Construction method for preventing hole wall from collapsing by manually digging hole through section steel support combination
The invention discloses a construction method for preventing a hole wall from collapsing by manually digging a hole through a section steel support combination, and relates to the technical field of pile foundation engineering hole-forming construction. An H-shaped steel reinforcing ring and a #-shaped square steel horizontal supporting piece are circumferentially embedded in a reinforced concrete retaining wall on the inner wall of a hole to form a reinforcing supporting structure, so that the collapse risk of the hole wall is reduced. The structural steel supporting combination of the H-shaped steel reinforcing ring and the #-shaped square steel horizontal supporting piece is adopted as a supporting structure for reinforcing the hole wall, the risk that the hole wall collapses in the manual hole digging operation process is effectively reduced, safety accidents possibly occurring in manual hole digging construction are reduced, and the construction efficiency is improved.
本发明公开了一种型钢支撑组合用于人工挖孔防止孔壁坍塌的施工方法，涉及桩基工程成孔施工技术领域，采用如下技术方案：人工挖孔作业过程中，通过在孔内壁上的钢筋混凝土护壁中周向埋置H型钢加强圈与井字形方钢水平支撑件形成加强支撑结构，以降低孔壁坍塌风险。本发明通过采用H型钢加强圈和井字形方钢水平支撑件的型钢支撑组合作为加强孔壁的支撑结构，有效降低了人工挖孔作业过程中孔壁坍塌的风险，降低了人工挖孔施工中可能发生的安全事故，提高了施工效率。
