Embodiment Construction
[0021] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0022] exist figure 1 , 2 , 3, A represents the facing soil side of the underground diaphragm wall, B represents the back soil side of the underground diaphragm wall, and C represents the ground.
[0023] The construction method for strengthening and sealing the I-shaped steel joints of the underground diaphragm wall includes the following specific steps:
[0024] Step 1. Weld the reinforcement cage in the first-phase construction groove section 3 of the underground diaphragm wall with the I-steel joint 1, and pre-embed two grouting grouts with a diameter of 25 to 30 mm on the side A of the flange plate facing the soil of the I-steel joint. Steel pipe 2; the top of grouting steel pipe 2 is 20-30cm higher than the ground C. The two grouting steel pipes are respectively located at both ends of the flange plate of the ...
