高速公路互通地道桥工程中的回旋钻施工技术探讨

Exploration of Rotary Drilling Construction Technology in Highway Interchange Tunnel Bridge Engineering

高速公路作为不同地区经济、文化联通的桥梁,是我国陆地交通体系的重要组成部分。保证高速公路工程施工质量对推动当地经济发展、解决民生问题有着重要意义。在路桥工程施工中,路基强化是极其重要的施工环节,虽然钻孔灌注桩施工技术日益成熟,但如果施工工艺选择不合理,依然会影响整体施工质量和工程进度。基于此,结合某高速公路互通地道桥工程案例,探究回旋钻施工技术应用措施,同时分析施工技术的应用难点,并提出相应的解决措施,旨在保障钻孔灌注桩整体的施工质量水平、提高路基工程使用安全性能、保障高速公路工程的综合建设效益。

As a bridge connecting the economy and culture of different regions,a highway is an important component of China's land transportation system.Ensuring the construction quality of highway engineering is of great significance for promoting local economic development and solving people's livelihood problems.In the construction of road and bridge engineering,roadbed reinforcement is an extremely important construction link.Although the construction technology of bored piles is becoming increasingly mature,improper construction techniques can still affect the overall construction quality and project progress.Based on this,this article combines a case study of a highway interchange bridge project to explore the application measures of rotary drilling construction technology.At the same time,it analyzes the application difficulties of construction technology and proposes corresponding solutions,aiming to ensure the overall construction quality level of bored piles,improve the safety performance of roadbed engineering,and ensure the comprehensive construction benefits of highway engineering.
