Bag type multi-isolation type anti-drag cast-in-place pile and construction method thereof
The invention discloses a bag type multi-isolation type anti-drag cast-in-place pile and a construction method thereof, and belongs to the technical field of pile foundation construction, the bag type multi-isolation type anti-drag cast-in-place pile comprises a reinforcement cage, concrete, an isolation film, an anti-drag film and an isolation bag, the lower end of the isolation film is connected with the reinforcement cage through a fixing strip, the isolation bag adheres to the lower end of the isolation film, the isolation film is wrapped with the anti-drag film, and the anti-drag film is arranged in the isolation bag. The lower end of the drag reduction film is bonded with the side, close to the drag reduction film, of the isolation bag, and the drag reduction film is extruded on the reinforcement cage through the isolation bag after grouting of the isolation bag. The construction method comprises the following steps: forming holes in the cast-in-place pile; lowering a reinforcement cage; grouting the isolation bag; and pouring concrete. The surface of the cast-in-place pile is covered with a multi-layer film structure, and therefore the problem that in the construction process of a soft soil area or a soil filling area and after-construction settlement influences a pile foundation is solved.
本发明公开了一种囊式多重隔离型减阻灌注桩及其施工方法，属于桩基施工技术领域，包括钢筋笼、混凝土、隔离膜、减阻膜、隔离囊袋，隔离膜的下端通过固定条带与钢筋笼连接，隔离囊袋粘结在隔离膜下端，减阻膜包裹在隔离膜外部，减阻膜的下端与隔离囊袋靠近减阻膜的一侧粘结，并在隔离囊袋注浆后通过隔离囊袋挤压在钢筋笼上。施工时按照如下方法操作：灌注桩成孔；下放钢筋笼；隔离囊袋注浆；混凝土浇筑。本发明通过在灌注桩表面覆盖多层膜结构进而达到消除软土地区或者填土地区施工过程中及工后沉降对桩基础影响的问题。
