AI Technical Summary

Technical Problem

The existing pile pull-out test device is too expensive, and the need to prefabricate a second support pier increases the overall cost.

Method used

Design a connection locking device for pile pull-out test, including an anchor plate, a first anchor beam, a connecting rod, a second anchor beam, a locking device, and a guiding device. The locking device fixes the reinforcing bars, and the anchor plate and connecting rod are driven by a jack to realize the pull-out test of the reinforcing bars, avoiding the need to build a second pier.

Benefits of technology

The cost of pile pull-out tests has been reduced by simplifying the device structure, reducing unnecessary construction steps, and improving testing efficiency.

Abstract

本实用新型提供一种基桩抗拔试验连接锁定装置,包括锚定板、设置在锚定板下方的第一锚定梁以及连接锚定板和第一锚定梁的连接杆,在第一锚定梁上方设有至少两个用于夹住钢筋的第二锚定梁,在第二锚定梁上方设有用于固定钢筋的固定件,在第二锚定梁上还设有夹紧钢筋的锁紧装置,在第一锚定梁和第二锚定梁之间设有导向装置,这样,通过锁紧装置就可以把第二锚定梁与钢筋固定在一起,第二锚定梁通过导向装置与第一锚定梁连接在一起,通过千斤顶向上带动锚定板向上运动,通过连接杆带动第二锚定梁向上运动,从而带动钢筋向上运动,从而测试基桩的抗拔性。这样就不需要像原有设计那样建造第二支墩,从而降低做基桩抗拔试验过程中的成本。
