Anti-drag cast-in-place pile with rigid isolating layer and construction method of anti-drag cast-in-place pile
The invention discloses an anti-drag cast-in-place pile with a rigid isolation layer and a construction method of the anti-drag cast-in-place pile, and belongs to the technical field of pile foundation construction. The anti-drag cast-in-place pile comprises a reinforcement cage, concrete and the rigid isolation layer, the rigid isolation layer is of a multi-section cylindrical structure, and each section of cylindrical structure is formed by combining two semicircular tile structures; the two semicircular tile structures are connected and fixed at the joint, the adjacent cylindrical structures are connected and fixed, the rigid isolation layer is of a thin-wall structure, the outer side of the rigid isolation layer is coated with an anti-drag material, the rigid isolation layer is fixed to the outer side of the reinforcement cage, the concrete is poured into the rigid isolation layer, and the concrete, the reinforcement cage and the rigid isolation layer jointly form an anti-drag cast-in-place pile structure. The construction method comprises the following steps: forming holes in the cast-in-place pile; preparing a reinforcement cage; lowering a reinforcement cage; and pouring concrete. The rigid isolation layer is segmented and sectioned, construction is facilitated, the outer side of the rigid isolation layer is coated with the drag reduction material and wrapped with the protective film, and the drag reduction effect is more remarkable.
本发明公开了一种带刚性隔离层的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、刚性隔离层，所述刚性隔离层为多节圆筒状结构，每节圆筒状结构由两片半圆状瓦片结构组合而成，两片半圆状瓦片结构在交接处连接固定，相邻圆筒状结构之间连接固定，刚性隔离层为薄壁结构，外侧涂覆有减阻材料，刚性隔离层固定在钢筋笼外侧，混凝土浇筑在刚性隔离层内部，与钢筋笼和刚性隔离层共同形成减阻灌注桩结构。施工时按照如下方法操作：灌注桩成孔；钢筋笼制备；下放钢筋笼；混凝土浇筑。本发明通过将刚性隔离层分段、分瓣处理，更利于施工，刚性隔离层的外侧涂覆有减阻材料并裹覆保护膜，减阻效果更加显著。
