Construction method for reconstructing bridge on expressway
The invention relates to a construction method for reconstructing a bridge on an expressway. The construction method comprises the following steps that 1, isolation protection is performed, wherein steel sheet pile cofferdam supporting is performed after a road surface is broken; 2, supporting is performed, specifically, anti-sliding piles are driven in the forward direction to serve as supports,and high-speed driving safety of a unconstructed side is guaranteed; 3, hole digging is performed, specifically, manual hole digging is performed on a to-be-constructed road surface to a pile top elevation; 4, pile foundation construction is performed, specifically, pile foundation construction is performed from a bottom of a hole dug manually in the step 3; 5, pile splicing is performed, specifically, pile splicing column construction is performed at a pile top in a manual hole digging hole; and 6, pier column construction is performed, specifically, pier column construction is performed in the manual hole digging hole in the step 3, and the inner wall of the hole is supported through a supporting structure.
本发明涉及一种高速公路改建桥梁的施工方法，包括以下步骤：步骤1，隔离防护：在路面破处后进行钢板桩围堰支护；步骤2，支撑：顺路向打设抗滑桩做为支撑，保证未施工一侧高速行车安全；步骤3，挖孔：在待施工路面上采用人工挖孔至桩顶标高；步骤4：桩基施工：从步骤3人工挖孔孔洞的底部进行桩基施工；步骤5，桩接：在人工挖孔孔洞内桩顶处进行桩接柱施工；步骤6，墩柱施工：在步骤3的人工挖孔孔洞内进行墩柱施工，并利用支撑结构对孔洞内壁进行支撑。
