承德地区钢铁水泥总厂30万吨水泥生产线施工过程中,多数单位工程设备基础预留螺栓孔较多,而且深度较大,最深的达2.7米。设备基础由于体积大,当混凝土浇筑完毕,下部混凝土已终凝。因此,用传统下木橛子或木盒的方法已无法施工。针对这种情况,我们采用了两种新的施工方法,即预制细石混凝土板盒法和纤维板盒灌 During the construction of the 300,000-ton cement production line of the Chengde Iron and Steel Cement Plant, most of the units of the engineering equipment had more bolt holes reserved, and the depth was relatively large, reaching a maximum depth of 2.7 meters. Because of the large size of the equipment foundation, when the concrete is poured, the lower concrete has finally set. Therefore, it has not been possible to construct using conventional wooden rakes or wooden boxes. In response to this situation, we have adopted two new construction methods, namely the prefabricated fine concrete slab box method and fiberboard box irrigation.
