河道护坡模具生产原理依据对不同区域的河道护坡砖型号而言，因为各个地区针对河道护坡塑料模具有专门的设计方案，所以需要的模具型号、外形都是不同的，比如湖北地区使用锁块护坡模具较 多，河南地区使用自锁式护坡模具较多，河北地区使用连锁护坡模具较多。所以根据地区对河道治理方案的不同、河道水质差异的不同，所设计的河道护坡砖都是符合各自区域特征的。
The production principle of river slope protection mould is based on the model of river slope protection brick in different regions. Because each region has a special design scheme for river slope protection plastic mould, the mould model and shape needed are different. For example, there are more lock block slope protection moulds in Hubei region, more self-locking slope protection moulds in Henan region, and chain slope protection moulds in Hebei region More. Therefore, according to the difference of river treatment plan and water quality in different regions, the designed river revetment bricks are in line with the characteristics of their respective regions.
