Three-drive penetration detection and pile bottom springback measurement device and method for rammed and expanded pile
The invention relates to the technical field of building construction, in particular to a device and method for detecting the three-drive penetration of a rammed and expanded pile and measuring the springback of the bottom of the rammed and expanded pile, and the distance of the top surface of a hammer is directly measured each time through a laser range finder. According to the utility model, the data is transmitted to the mobile phone in time through the Bluetooth, the penetration and the final rebound amount of each time of compaction are mastered in time, the error problem caused by the fact that the tightness of the steel wire rope needs to be considered during manual measurement of the steel wire rope is avoided, the error reaches a millimeter level, and the measurement accuracy is improved. The detection precision is improved, potential safety hazards caused by manual measurement of hoisting equipment are avoided, and three-drive penetration detection and pile bottom springback measurement are rapid, correct and safe.
本发明涉及建筑施工技术领域，具体涉及一种夯扩桩的三击贯入度检测和桩底回弹的测量装置和方法，通过激光测距仪每次直接测量锤顶面的距离，由于钢质材料非标准柱锤的不可压缩性，即相当于直接测量了载体每次夯击的贯入度及最后的反弹量，通过蓝牙将数据及时传递给手机，即时掌握每一次夯击的贯入度以及最终回弹量，避免了人工测量钢丝绳要考虑钢丝绳绷紧度带来的误差问题，使得误差达到毫米极，提高了检测精度，也避免了在起吊设备人工测量带来的安全隐患，使得三击贯入度检测和桩底回弹的的测量快捷，正确，安全。
