The side wall 1 of the elevator shaft foundation pit is a reinforced concrete structure and a waterproof structure constructed on site according to design requirements. A new side wall 2 is formed by adding a reinforced concrete structure around the side wall 1 of the elevator shaft foundation pit according to the original design method. The method for constructing the new side wall 2 is the same as that for constructing the side wall 1 of the elevator shaft foundation pit. The new side wall 2 is made of anti-seepage concrete. A water drainage interlayer 4 with a width of 80-100 mm is reserved between the side wall 1 of the elevator shaft foundation pit and the new side wall 2.
