Cast-in-situ bored pile underwater concrete pouring guide pipe automatic lifting device and method
The invention discloses a cast-in-situ bored pile underwater concrete pouring guide pipe automatic lifting device and method. The cast-in-situ bored pile underwater concrete pouring guide pipe automatic lifting device comprises an elevator, a guide pipe fixing device controller and a concrete surface height measuring device, wherein the elevator is composed of an automatic lifting machine, a clamping mechanism and a rotating disc, the clamping mechanism is connected with the rotating disc through a connecting arm I, an electric lifting rod is arranged on the automatic lifting machine, a mechanical support used for supporting a funnel is installed on the upper portion of the electric lifting rod, and the concrete surface height measuring device is composed of a liquid pressure sensor and anultrasonic detection device. According to the automatic lifting device, the lifting speed of the automatic lifting machine is preset by analyzing the underwater concrete pouring volume and the pile body diameter of a cast-in-situ bored pile, and the height of a guide pipe buried into the concrete surface is judged through the pressure sensor and the ultrasonic detection device, so that the lifting speed is automatically adjusted, the guide pipe can be stably lifted at a constant speed during underwater concrete pouring, and the depth of the guide pipe buried in concrete is controlled.
本发明公开了一种钻孔灌注桩水下砼灌注导管自动提升装置及方法，包括提升机、导管固定装置控制器及混凝土面高度测量装置，所述提升机由自动升降机、夹取机构、旋转盘组成，所述夹取机构通过连接臂Ⅰ与旋转盘相连，所述自动升降机上设有电动升降杆，所述电动升降杆上部安装有用于支撑漏斗的机械支架，所述混凝土面高度测量装置由液体压力传感器与超声波检测装置组成。本发明通过分析钻孔灌注桩水下砼灌注方量与桩身直径预设自动升降机提升速度，通过压力传感器和超声波检测装置判断导管埋入混凝土面的高度，从而对提升速度进行自动调节，可以在水下砼灌注时匀速平稳的提升导管，控制导管埋入混凝土的深度。
