[0024] The grouting construction method of the large-diameter rock-socketed single pile of offshore wind power is further explained below in conjunction with the attached drawings.
[0025] figure 1 , 2 , 3 shows the prefabricated grouting pipe structure diagram of the steel pipe pile. The inner wall of the steel pipe pile 1 is provided with two first prefabricated grouting pipes 3 fixed by a plurality of first support rods 3a and two second prefabricated grouting pipes 4 fixed by a plurality of second support rods 4a. The first prefabricated The grouting pipe 3 and the second prefabricated grouting pipe 4 are evenly distributed on the inner wall of the steel pipe pile 1 alternately. The first prefabricated grouting pipe 3 communicates with a first grouting port 3b provided on the pile wall, and the second prefabricated grouting pipe 4 communicates with a second grouting port 4b provided on the pile wall. The second grouting port 4b is located above the first grouting port 3b, a...
