Pile hole detection device in pile foundation construction
The invention discloses a pile hole detection device in pile foundation construction, which comprises a reference positioning part mounted on a steel casing, a main retractor is arranged on the reference positioning part, the main retractor is connected with a falling disc through a lifting rope, the reference positioning part comprises a disc body and a central turntable, a central round hole is formed in the disc body, and the central turntable is connected with the main retractor through a lifting rope. The central turntable is assembled in a central circular hole of the disc body and consists of a base position ring plate and an inner tray; compared with the prior art, the device has the beneficial effects that when the depth of a pile hole of a pile foundation is detected, the falling disc is lifted to the bottom of the pile hole, in the process, whether the falling disc is in a horizontal state or not can be observed by observing whether the lengths of the two auxiliary ropes are equal or not, and at the moment, the lifting rope is in a vertical state; in addition, when the device is used for detecting the pile hole, accumulated water does not affect the detection accuracy even if the accumulated water exists at the bottom of the pile hole.
本发明公开了一种桩基施工中桩孔检测装置，包括安装在钢护筒上的基准定位部，基准定位部上设置有主卷收器，主卷收器通过吊绳连接有坠盘，基准定位部包括圆盘体和中心转盘，圆盘体上设置有中心圆孔，中心转盘装配在圆盘体的中心圆孔内，中心转盘由基位环板和内托盘组成；与现有技术相对比，本发明的有益效果是：在对桩基的桩孔深度检测时，将坠盘吊送至位于桩孔底部，此过程中，通过观察两个辅助绳的长度是否相等，可以观察到坠盘是否为水平状态，此时吊绳为竖直状态，可以避免吊绳倾斜而影响检测结果的准确度，另外，通过本装置对桩孔进行检测，即使桩孔底部存在着积水，积水不会对检测准确度造成影响。
