Pile head breaking method based on steel bar sleeve
The invention discloses a pile head breaking and removing method based on a steel bar sleeve and belongs to the technical field of pile foundation construction, a steel bar cage of a pile head comprises a plurality of longitudinal bars which are annularly and evenly distributed and annular stirrups connected with the longitudinal bars, and the pile head breaking and removing method comprises the following steps that parts are prefabricated, and the steel bar cage, a floating ring, a threaded limiting block, the sleeve and a sealing cover are prefabricated in a factory; the floating ring is provided with a center hole for a longitudinal bar of the reinforcement cage to penetrate through, and the threaded limiting block is provided with a threaded hole matched with the longitudinal bar. Mounting a sleeve on the pile head; lowering a reinforcement cage, namely lowering the reinforcement cage to a specified elevation by using a crane; concrete is poured, concrete is poured into the pile hole, and during pouring, the concrete is prevented from being directly poured on the surface of the floating ring; the pile head is broken, and pile head concrete is broken; and the pile head is hoisted, the broken pile head is hoisted, and it is guaranteed that the steel bars cannot be damaged in the hoisting process. The method can prevent buoyancy of concrete grout from affecting the casing pipe, and the construction efficiency is improved.
本发明公开了一种基于钢筋套管的桩头破除方法，属于桩基施工技术领域，桩头的钢筋笼包括若干环形均布的纵筋以及连接所述纵筋的环形箍筋，桩头的破除方法包括以下步骤：预制零部件，工厂预制钢筋笼、浮动环、螺纹限位块、套管和封盖，在浮动环上开设用于钢筋笼的纵筋穿过的中心孔，所述螺纹限位块上开设有与纵筋配合的螺纹孔；桩头安装套管；下放钢筋笼，钢筋笼采用吊车下放至指定标高；灌注混凝土，向桩孔内灌注混凝土，浇筑时，避免混凝土直接倾注在浮动环表面；顶断桩头，顶断桩头混凝土；桩头起吊，将顶断的桩头吊起，保证钢筋不会再起吊过程中发生破坏。本发明方法可以防止混凝土浆液的浮力对套管造成影响，提高施工效率。
