北京轻汽工程是中建一局二公司的重点项目,第一期工程冲压联合厂房建筑面积近40000m~2。该厂房的设备地沟是整个工程的心脏部位。地沟上安装多台进口冲压设备,其基础深达9m。各条地沟相连通,总计混凝土工程量8000m~3。设计要求采用B_8级C23级混凝土,沟壁板外侧做聚氨酯防水涂层。由于该地区地下水位高(-1m)、基础深和施工条件所限,设备地沟的混凝土工
Beijing Light Automotive Engineering Co., Ltd. is a key project of the Second Construction Company of China Construction First Bureau. The construction area of the first-phase project stamped joint workshop is nearly 40,000 m2. The facility’s equipment trench is the heart of the entire project. Several imported stamping equipments are installed on the trench, and its foundation is 9m deep. Each trench is connected and the total concrete volume is 8000m~3. The design requires the use of B_8 grade C23 concrete, with polyurethane waterproof coating on the outside of the groove wall. Due to the high groundwater level in the area (-1m), foundation depth, and construction conditions, concrete equipment for equipment trenches
