Retard-bonded prestressed uplift pile connecting device and construction method thereof
The invention discloses a retard-bonded prestressed uplift pile connecting device and a construction method thereof, and aims to provide the retard-bonded prestressed uplift pile connecting device capable of effectively avoiding a problem of water seepage of a basement bottom plate as a result of water seepage between a sleeve and the basement bottom plate under the condition that the anti-floating requirement of a basement is met as well as a construction method thereof. The retard-bonded prestressed uplift pile connecting device comprises anchoring steel bars anchored in the basement bottom plate; an uplift pile located below the basement bottom plate; a lower prestressed anchoring device which comprises a lower anchorage device embedded in the lower portion of the uplift pile, a prestressed anchorage device fixed to the top of the uplift pile and a retard-bonded prestressed steel strand, wherein the retard-bonded prestressed steel strand comprises a lower prestressed steel strand connecting the lower anchorage device and the prestressed anchorage device; and an adapting piece connected with the prestressed anchorage device, wherein the anchoring steel bar is connected with the adapting piece.
本发明公开了一种缓粘结预应力抗拔桩连接装置及其施工方法，旨在提供一种能够在满足地下室抗浮要求的情况下，有效避免因套管与地下室底板间容易渗水，而导致地下室底板出现渗水的问题的缓粘结预应力抗拔桩连接装置及其施工方法。缓粘结预应力抗拔桩连接装置，包括：锚固钢筋,锚固钢筋锚固于地下室底板内；抗拔桩，抗拔桩位于地下室底板下方；下部预应力锚固装置，下部预应力锚固装置包括埋设在抗拔桩下部内的下部锚具、固定在抗拔桩的桩顶的预应力锚具及缓粘结预应力钢绞线，缓粘结预应力钢绞线包括连接下部锚具与预应力锚具的下部预应力钢绞线；转接件，转接件与预应力锚具相连接，所述锚固钢筋与转接件相连接。
