复杂地质条件下锁扣钢管桩深水围堰施工

Construction of Deep-Water Cofferdam with Locking Steel Pipe Piles Under Complicated Geological Conditions

锁扣钢管桩深水围堰施工是建设桥梁过程中的重要组成部分。尤其是在面对深水情况时,是深基坑开挖过程中支护与止水的关键措施,能够充分保证桥梁建设的正常进度。但是在复杂的地质条件下,往往使用的技术和处理方法各有不同。所以,本文主要介绍复杂地质条件下锁扣钢管桩深水围堰施工的措施,以及介绍在施工过程中加工、插打、合龙以及挖泥封底等施工工艺,促进我国的桥梁建设事业发展,为我国建立多元立体的交通网奠定基础。

The construction of deep-water cofferdams with locking steel pipe piles is an important part in the process of bridge construction.Especially when facing deep water conditions,it is a key measure for supporting and stopping water during the excavation of deep foundation pits,which can fully guarantee the normal progress of bridge construction.However,under complex geological conditions,different technologies and treatment methods are often used.Therefore,this article mainly introduces the construction measures of deep-water cofferdams with locking steel pipe piles under complex geological conditions,as well as the construction techniques in the construction process,such as processing,drilling,closing,dredging and sealing,so as to promote the development of bridge construction in China and lay the foundation for establishing a diversified and three-dimensional transportation network in China.
