Abstract

The invention belongs to the technical field of cement base material underwater foundation construction, and particularly relates to a construction method of underwater concrete grouting. The construction method includes the following steps of cofferdams, pipes burying, enrockment, mechanical drainage and grouting. According to the technical scheme, compared with the prior art, the construction method has the following advantages that lateral supports do not need to be pre-arranged in the cofferdams; the amount of the mechanical drainage is reduced, and the cost is lowered; and the qualities of stone piling and grouting are high, and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of underwater foundation construction of cement-based materials, and in particular relates to an underwater concrete pouring construction method. Background technique [0002] With the development of social economy and the continuous progress of science and technology, the resources needed for the development of human society are also increasing. In the context of increasingly scarce land resources, the development of marine resources, which accounts for 70% of the earth's area, is particularly important. Therefore, the development and utilization of marine resources is the only way for the development of human society. Marine structures, such as sea-crossing bridges, offshore platforms, seawalls, revetments, breakwaters, subsea tunnels and artificial islands, have also become research hotspots in the engineering field. [0003] The method of cofferdam drainage is generally used for underwater concrete pour...
