Research on Construction Technology of Bored Pile for Highway Bridge Foundation
The construction of the highway bridge foundation mud wall protection is the most critical part of the expressway bridge construction,and its construction quality directly affects the quality of the whole project.So this paper proposes the construction technology of bored pile of highway bridge foundation.The steel with high strength and durability is selected as the cylinder material,and specific specifications are de-signed according to the engineering requirements.In the drilling stage,according to the three main stages of drilling,and drilling,with im-proved diameter of 2.5m in the drilling stage,the drill as the specific drilling device.
