step three: taking a common steel pipe as a raw material, cutting one section of the common steel pipe, forming a jack at the lower end of the common steel pipe by using a drilling machine to prepare a cylindrical auxiliary component 33, inserting a pin shaft 33a into the jack, wherein the outer diameter of the auxiliary component 33 is 4-8mm larger than the diameter of a connecting component;
step four: when the first wall body 44 is poured, the lower ends of a plurality of connecting members 11 are uniformly embedded on the upper side of the first wall body 33a, a restraining member 22 is coaxially embedded on the periphery of the lower end of each connecting member 11, and the first wall body 33a is waited for to be completely solidified;
step five: when the second wall body 55 is poured, the lower ends of a plurality of auxiliary components 33 are uniformly embedded into the upper side of the second wall body 5, a constraint component 22 is coaxially embedded into the periphery of the lower end of each auxiliary component 33, and the second wall body 55 is waited for being completely solidified;
