扭王字块（accropode），护面块体的一种，由三个杆件组成，两端杆件平行，中间的杆件正交于两端杆件，形状上像汉字的“王”字中间一横90度扭转，又叫“扭王体”或“钩连块体”。材料为混凝土，通过定型模板一次性浇筑完成，一般为纯混凝土浇筑，但当扭王字块重量大于40t时，应予配置钢筋或其他防断裂的加强措施，例如加大腰杆的直径尺寸等，以加强块体的抗断裂能力。一般安放在防波堤最外面一层，通过削弱波浪的冲击力保护防波堤。
Accropode is a kind of armor block, which is composed of three bars. The bars at both ends are parallel, and the bars in the middle are orthogonal to the bars at both ends. The shape of Accropode is like the Chinese character "Wang" with a 90 degree twist in the middle. It is also called "Accropode" or "hook block". The material is concrete, which is poured by setting formwork at one time, which is generally pure concrete pouring. However, when the weight of Accropode is greater than 40t, reinforcement or other anti fracture strengthening measures should be provided, such as increasing the diameter of waist pole, etc., to strengthen the anti fracture capacity of the block. It is usually placed on the outermost layer of the breakwater to protect the breakwater by weakening the impact of waves.
