Method for rapidly separating embedded part from pile head of cast-in-place pile
The invention discloses a method for rapidly separating a cast-in-place pile head from an embedded part, and belongs to the technical field of pile foundation construction. The method comprises the steps that a plurality of sliding sleeves slide to the positions of main reinforcements of the reinforcement cage on an annular sliding rail to be sleeved with the sliding sleeves; after the reinforcement cage is hoisted into the pile hole, the reinforcement cage is slowly put down; a single-strand first steel wire rope and a single-strand second steel wire rope penetrate through the second folding isolator and the third folding isolator respectively and then are divided into two strands; pouring the concrete to a position 10 centimeters above the designed elevation and then stopping pouring; after the pile foundation is excavated, steel bars are inserted into the invalid pile head horizontal drill holes, and the pile head can be directly hoisted; and after the invalid pile head is hoisted and broken, the semicircular first folding isolator is dismounted, polished and coated with a release agent and then can be reused. The device is easy to install and convenient to operate, pile head concrete can be effectively and rapidly isolated in the pile foundation pouring process, one-time pile breaking in the later period is facilitated, and the construction operation time is shortened.
本发明公开了一种灌注桩桩头快速分离预埋件的方法，属于桩基施工技术领域。本发明的步骤为：将若干个滑动套筒在环形滑轨上分别滑至钢筋笼主筋位置套上；将钢筋笼吊入桩孔中后，缓慢放下；将单股第一钢丝绳、第二钢丝绳分别从第二折叠隔离器、第三折叠隔离器内穿过后并作两股；将混凝土灌注至设计标高以上10公分处后停止灌注；待桩基开挖后，在无效桩头水平钻孔插入钢筋，即可直接吊起桩头；无效桩头起吊破除后，拆除半圆第一折叠隔离器打磨涂刷脱模剂后可再次利用。本发明安装简单，操作便捷，能够有效快速的在桩基灌注过程中隔离桩头混凝土，方便后期一次性破桩，减少施工作业时间。
