Shield tunnel anti-floating structure and construction method thereof
The invention discloses a shield tunnel anti-floating structure and a construction method thereof, and aims to provide the shield tunnel anti-floating structure which is good in shield tunnel anti-floating effect, does not intrude into a tunnel building limit, and does not affect pipeline routing and train operation in a tunnel building space, and the construction method of the shield tunnel anti-floating structure. A shield tunnel anti-floating structure comprises an anti-floating unit, and the anti-floating unit comprises a preset steel plate fixed to the inner wall of a shield segment, a reserved grouting hole is formed in the position, where the preset steel plate is located, of the shield segment, and a steel plate via hole corresponding to the reserved grouting hole is formed in the preset steel plate; the cement-soil pile is located in a soil layer on the outer side of the shield segment, and one end of the cement-soil pile is close to or abuts against the outer wall of the shield segment; and one end of the anti-floating component is fixedly connected with the preset steel plate, and the other end of the anti-floating component sequentially penetrates through the steel plate via hole and the reserved grouting hole and is inserted into the cement soil pile.
本发明公开了一种盾构隧道抗浮结构及其施工方法，旨在提供一种不仅盾构隧道抗浮效果好，而且不侵入隧道建筑限界，不影响隧道建筑空间内的管道走线和列车运营的一种盾构隧道抗浮结构及其施工方法。一种盾构隧道抗浮结构，包括抗浮单元，其包括：预置钢板，固定在盾构管片内壁上，预置钢板所在的盾构管片处设有预留注浆孔，且预置钢板上设有与预留注浆孔对应的钢板过孔；水泥土桩，位于盾构管片外侧的土层内，水泥土桩一端靠近或抵接在盾构管片的外壁上；抗浮构件，抗浮构件一端与预置钢板固定连接，抗浮构件另一端依次穿过钢板过孔与预留注浆孔并插入水泥土桩内。
