AI Technical Summary

Technical Problem

Traditional pile group settlement control methods suffer from slow project progress, high costs, and unreasonable load sharing between new and old piles, resulting in large differential deformations that may lead to cracking or damage to the pile cap.

Method used

The system employs both old and new pile leveling systems, combining electric control and traditional mechanical adjustment. Through the coordinated action of devices such as motors, springs, load plates, and hydraulic rods, the settlement of old piles is adjusted, while the settlement of new piles is monitored by flexible reinforcement capsules and strain gauges, thereby achieving differential settlement control.

Benefits of technology

It improves the efficiency and accuracy of pile group settlement control, prevents uneven settlement between new and old piles, prevents engineering accidents, and reduces time and economic costs.

Abstract

本发明涉及群桩沉降调控技术领域,具体为一种混合群桩不均匀沉降调控装置,在多根旧桩之间贯入新桩,新桩与多根旧桩组成新旧混合桩基,具体包括:旧桩调平系统,包括设置在各个旧桩顶部的沉降调整装置,以及设置在各个旧桩桩侧的侧向防位移装置;新桩调平系统,设置在新桩的桩侧及桩底,用于调节新桩的竖向位移并为新桩提供侧向支撑。与现有技术相比,本发明能够有效预防新旧混合群桩不均匀沉降的发生,群桩沉降时发生倾斜,以及防止沉降时桩周土体变形对邻近桩基沉降的影响。相较于重新打桩或拔桩所花费的人力物力财力大大的减少。与现有技术相比,本发明具有结构配置简洁、施工安装便捷、差异沉降调控效果显著及造价经济等优点。
