卸荷板在车陂涌除险加固工程中的应用

Application of Unloading Plate to Chebei River Surge Reinforcement Project

车陂涌车陂公园对面段长约95 m的堤顶路面出现了变形开裂,经现场调查及分析计算,主要原因是因为现状堤岸挡墙无序加高,导致挡墙结构安全储备不能满足要求,加上堤后道路经常行走重车,存在一定的安全隐患,为确保堤防及周边建筑物的安全,需对该段堤岸进行除险加固处理。因河涌周边建筑物密集,对堤岸进行整体拆除重建,代价将相当昂贵,可操作性非常低;而根据实际地形情况,采取增设卸荷板结构的形式,在工期、造价及实施难度上都能较好的满足要求。该方法结构简单,可操作性强,非常适用于城中村、密集小区、临近道路等地段城市河涌的抢险加固工程。

The part of Chebei creek to the opposite side of Chebei Park,had about 95 m longed formation cracks at the top of the road. Through field investigation and analysis,the main reason is the present situation of embankment retaining wall disorderly heightening,leading to safety retaining wall structure can ＇t meet the requirements. And after the road embankment often walking heavy vehicles,there are some security risks. In order to ensure embankment and the safety of the surrounding buildings,the embankment reinforcement treatment is in urge need. Due to the creek dense surrounding buildings,the bank overall demolition and reconstruction,the price will be very expensive and operability is very low; However,according to the actual situation,adding the unloading board structure form can meet the requirement of construction period,cost,demand the difficulty of implementation. This method has the advantages of simple structure,easy operation,strong operability,and is very suitable for the village,dense area,road area of the city near the river rescue and reinforcement engineering.
