Characteristic (Bottom feed vibroflotation device barge type)

Bottom feed vibroflotation device barge type effectively solves the construction problems faced by underwater Vibroflotation Gravel Pile Construction in the following aspects:

a) Construction platform problem: underwater construction needs to form construction space through cofferdam construction, otherwise it is necessary to set up construction platform or configure construction barge on the water surface.

b) Supporting equipment: due to the particularity of underwater construction, it is necessary to configure a large number of complex special supporting tools and equipment suitable for underwater construction.

c) The process of pile and stone delivery under water must be an effective problem. In the previous underwater construction cases using the traditional vibroflotation method, due to the existence of the above problems, the vibroflotation construction cost is higher, the efficiency is low, and the construction quality is difficult to guarantee.
