The underwater riprap deviceis high in transportation efficiency and longin service life.

Description

Technical field [0001] The invention relates to the technical field of underwater engineering construction equipment, in particular to an underwater rock dumping device. Background technique [0002] In the construction of the breakwater protection surface, some large rocks are often added to increase the strength of the breakwater, especially in deep waters. The traditional method of adding large rocks during the construction process is a net bag or grab bucket for transportation and throwing. Stones are thrown in net bags, the construction accuracy is difficult to control, and the life of the net bags is short. The use of grabs for stone dumping has limited volume and low construction efficiency. Therefore, a design with high construction accuracy and high construction efficiency is designed. The long-life stone dumping device is of great significance. Summary of the invention [0003] An object of the present invention is to solve at least the above-mentioned problems and to p...

Problems solved by technology

[0002] In the construction of breakwater protection, some large stones are often added to increase the strength of the breakwater, especially in deep waters. During the construction process, the traditional way of adding large stones is to transport and throw them with net bags or grab buckets. For riprapping stones, it is difficult to control the construction accuracy by using a net bag, and the broken net bag has a short service life; using a grab bucket for riprap, the volume of the grab bucket is limited, and the construction efficiency is low. Therefore, a design with high construction accuracy and high construction efficiency, Long-life ripraps make a lot of sense
