Blanking guide pipe construction device and method for cast-in-situ bored pile
The invention discloses a cast-in-situ bored pile discharging guide pipe construction device and method.The device comprises a supporting frame, a plurality of pushing adjusting type pipe conveying mechanisms and a plurality of pressure detection mechanisms which are in one-to-one correspondence are installed on the supporting frame, and one end of each pushing adjusting type pipe conveying mechanism abuts against the peripheral face of a discharging guide pipe; one end of each pressure detection mechanism abuts against the peripheral face of the discharging guide pipe, a feeding type guide pipe connecting mechanism is installed on the supporting frame, and a driving mechanism is installed on the supporting frame. According to the method, feeding, continuing and lowering operation of the discharging guide pipe is achieved based on the device, after lowering is completed, concrete pouring is conducted, and the discharging guide pipe is gradually lifted and recycled. It is ensured that the discharging guide pipe is lowered and lifted up according to the preset speed, the problem that the continuous discharging guide pipe deflects in the process is solved, mutual scraping and pulling of the discharging guide pipe and a reinforcement cage are avoided, the quality of a cast-in-place pile is improved, and the labor intensity is reduced. The method is suitable for the technical field of cast-in-situ bored pile construction.
本发明公开了一种钻孔灌注桩下料导管施工装置及方法，装置包括支撑架，支撑架上安装有一一对应的多个顶推调整式输管机构和多个压力检测机构，各顶推调整式输管机构的一端顶接于下料导管的外周面上，各压力检测机构的一端顶接于下料导管的外周面上，支撑架上安装有上料式导管接续机构，支撑架上安装有驱动机构；方法基于上述的装置来实现对下料导管的上料、接续及下放作业，待下放完毕后，进行混凝土灌注，并逐渐上提、回收下料导管。本发明确保下料导管按照预定的速度下放及上提，并且在此过程中防止接续的下料导管出现偏斜的问题，避免下料导管与钢筋笼相互刮拉，提高灌注桩的质量，降低劳动强度。本发明适用于钻孔灌注桩施工的技术领域。
