水泥預制防潮石模具主要用于南方地帶，海邊、碼頭等地區使用，起到波浪阻力的作用。 　　　　四腳空心塊作為一種常見的消浪塊體，與扭王字塊、四腳錐體和扭工字塊等相比，該塊體不僅具有投資少、施工方便、外形美觀、孔隙率高等優點，而且利用與相鄰塊體之間的摩擦力保持單個塊體的穩定，使每個塊體水動力穩定性的差異性很小、整體穩定性更好，此產品應用在氣候條件不惡劣的外海或趕潮段的護面消浪結構中。 　　常見的規格尺寸：15015040cm、13013030cm、11011030cm、909030cmThe cement prefabricated damp proof stone mould is mainly used in the south, seaside, wharf and other areas, playing the role of wave resistance. As a common wave dissipating block, the four foot hollow block not only has the advantages of less investment, convenient construction, beautiful appearance and high porosity, but also uses the friction between adjacent blocks to maintain the stability of a single block, so that the difference of hydrodynamic stability of each block is very small and the overall stability is better, This product is used in the structure of wave protection and dissipation in the open sea or in the tidal section where the weather conditions are not bad. Common sizes: 150 150 40cm, 130 130 30cm, 110 110 30cm, 90 90 30cm
