Construction method for reverse opening well shaft
The invention discloses a construction method of a reverse opening well shaft, which comprises the following steps of: driving a steel casing underground until the bottom of the steel casing is in contact with the outer wall of a pipe joint of an underground jacking pipe; earthwork in the steel casing is excavated, and a working face in the steel casing is cleaned; a steel shaft with the height ranging from 50 cm to 60 cm is hoisted to the inner bottom of the steel casing, the position of the steel shaft is manually adjusted, and the steel shaft and the jacking pipe joint are welded; filling quick-drying waterproof mortar between the steel shaft and the steel casing; removing the outer steel plate of the pipe jacking section in the steel shaft, breaking the concrete of the pipe section and cutting off the steel bar of the pipe section; the hoisting concrete prefabricated shaft is mounted at the upper part of the steel shaft; and plain concrete is filled between the concrete prefabricated shaft and the steel casing and is vibrated and compacted. When the method is adopted to construct the steel shaft, the space in the steel casing is used as the working space, and the working space reaches the maximum.
本发明公开了一种反开井井筒施工方法，包括步骤为：向地下打设钢护筒，直至钢护筒底部与地下顶管的管节外壁接触；开挖钢护筒内土方并清理钢护筒内工作面；将高度为50cm‑60cm的钢井筒吊放至钢护筒内底部并人工调整钢井筒位置，将钢井筒与顶管管节焊接；在钢井筒与钢护筒之间填筑快干防水砂浆；除位于钢井筒内区域的顶管管节的外包钢板、破除管节混凝土并切除管节钢筋；吊放混凝土预制井筒安装于钢井筒上部；在混凝土预制井筒与钢护筒之间填筑素混凝土并振捣密实。采用本方法在施工钢井筒的时候，以钢护筒内的空间为工作空间，工作空间达到最大。
