济南美里湖开发区最近利用黄河淤泥开发生产出了一种多孔砖。这不仅为烧砖找到了源源不断的原料 ,而且为黄河清淤、疏浚河道作出了重大贡献。生产粘土砖要消耗大量的上好土地 ,且日益受到限制 ,而黄河不断沉积的淤泥又不断抬高河床 ,迫使河水上溢 ,出现险情。利用黄河淤泥生产 The Lianyungang Lake Development Zone in Jilin has recently used the Yellow River silt to develop a porous brick. This not only finds a steady supply of raw materials for bricks but also makes a significant contribution to the dredging and dredging of the Yellow River. The production of clay bricks consumes a large amount of good land and is increasingly restricted, and the continuously deposited silt of the Yellow River continues to raise the riverbed, forcing the river to overflow and causing dangerous conditions.
