Construction method for fixing anti-floating cage by pipe sinking cast-in-place pile shoe and cage bottom hook net
The invention relates to the technical field of immersed tube cast-in-place pile construction, and discloses an immersed tube cast-in-place pile shoe and cage bottom hook net fixed anti-floating cage construction method which comprises the following steps that S10, a pile shoe is prefabricated, and a plurality of pile shoe barbs are arranged at the bottom of the pile shoe; s20, pile position measurement and setting-out are conducted, and pile shoes are embedded; s30, the pile machine is in place, and the pile shoe is sleeved with the bottom end of the sleeve; s40, the casing pipe is sunk, and the pile shoe is sunk to the designed elevation along with the casing pipe; s50, a reinforcement cage is hung in the sleeve; a grid frame is additionally arranged at the bottom end of the reinforcement cage, and the barb part hooks the grid frame; s60, pile body concrete is poured into the casing pipe; and S70, the casing pipe is pulled out through vibration to form a pile. When the reinforcement cage is hoisted and placed, the grid frame at the bottom of the reinforcement cage is hooked with the pile shoe barb on the pile shoe, and once the reinforcement cage floats upwards due to stress, the pile shoe at the bottom of the sleeve firmly hooks the reinforcement cage through the pile shoe barb, so that the reinforcement cage can be effectively prevented from floating upwards, and the service life of the reinforcement cage is prolonged. And the pile body quality of the cast-in-place pile is prevented from being influenced by upward floating of the reinforcement cage.
本发明涉及沉管灌注桩施工的技术领域，公开了沉管灌注桩桩靴与笼底钩网固定防浮笼施工方法，包括以下步骤：S10：预制好桩靴，桩靴底部设有多个桩靴倒钩；S20：桩位测量放线，埋设桩靴；S30：桩机就位，套管的底端套入桩靴；S40：沉入套管，并使桩靴随套管一起沉入至设计标高；S50：在套管内吊放钢筋笼；在钢筋笼的底端加设网格架，倒钩部勾住网格架；S60：在套管内灌注桩身混凝土；S70：振动拔出套管成桩。在吊放钢筋笼时使钢筋笼底部的网格架与桩靴上的桩靴倒钩相钩连，一旦出现钢筋笼受力上浮的情况时，套管底的桩靴通过桩靴倒钩将钢筋笼牢固钩挂住，从而可有效防止钢筋笼上浮，避免了因钢筋笼上浮导致灌注桩的桩身质量受到影响。
