摘要
近年来,石马河河道两岸修建了大量建筑,部分河段有占滩及缩窄河道现象。石马河现状基本上无堤防,河道壅塞重、防洪标准低、排洪能力差,易造成洪涝灾害。石马河干流塘厦镇段现状十余座桥梁不满足防洪设计要求,阻水严重,需进行改扩建。论文以莲湖新桥拆除为例,阐述桥梁拆除施工方案的选择、拆除原则与重难点,详细介绍了莲湖新桥的拆除过程。
In recent years,a large number of buildings have been built on both sides of the Shima River,and some sections of the river have occupied the beach and narrowed the river.The current situation of Shima River is basically no levee,heavy congestion,low flood control standards,poor flood discharge capacity,easy to cause flood disaster.At present,more than ten bridges in Tangxia Town section of the main stream of Shima River do not meet the design requirements of flood control and have serious water obstruction,so they need to be rebuilt and expanded.Taking the demolition of Lianhu New Bridge as an example,the paper expounds the selection of the construction scheme,the principles and difficulties of the demolition,and introduces the demolition process of Lianhu New Bridge in detail.
