Description

一种船载混凝土生产***及方法Shipborne concrete production system and method 技术领域Technical Field
本发明属于水上混凝土拌合技术领域，涉及一种船载混凝土生产***及方法。The invention belongs to the technical field of water concrete mixing, and relates to a shipborne concrete production system and method.
背景技术Background technique
水下混凝土浇筑混过程中，混凝土连续生产和环保是非常关键的因素。布置在陆地上的混凝土生产设施，长距离运输混凝土会大大降低混凝土浇筑的经济性，对于桥墩等小方量分散的混凝土浇筑项目，该项缺点表现更为突出。In the process of underwater concrete pouring, continuous concrete production and environmental protection are very critical factors. For concrete production facilities arranged on land, long-distance concrete transportation will greatly reduce the economy of concrete pouring. For concrete pouring projects with small and dispersed volumes such as bridge piers, this disadvantage is more prominent.
现有技术中，已有发明人设计混凝土搅拌船，例如公开号为CN 104260209 A的中国专利申请，提出了一种内河航道水上移动混凝土搅拌船，该专利通过调整安装设备的位置和空间布局，提高船体的平衡性，但没有考虑船体在装载和生产的动态过程中如何维持船体的平衡性，也没有兼顾清淤功能和利用清淤物生产砂石和生产用水，且该混凝土搅拌船没有考虑污废处理，混凝土搅拌船上的生产和生活污水对水体污染较大，易造成生态破坏和影响。In the prior art, some inventors have designed concrete mixer boats. For example, the Chinese patent application with publication number CN 104260209 A proposes a mobile concrete mixer boat for inland waterways. The patent improves the balance of the hull by adjusting the position and spatial layout of the installation equipment, but does not consider how to maintain the balance of the hull during the dynamic process of loading and production, nor does it take into account the dredging function and the use of dredged materials to produce sand and gravel and production water. In addition, the concrete mixer boat does not consider waste treatment. The production and domestic sewage on the concrete mixer boat seriously pollutes the water body, which is easy to cause ecological damage and impact.
