Preferably, steel stiffening plates are arranged at the joints of the steel pipe piles and the steel shear braces in the horizontal direction and the vertical direction, so that the local rigidity of the joints is increased, and the problem of stress concentration at the joints is reduced.
Preferably, the embedded steel bars are of U-shaped structures and are arranged in a double-limb mode, so that the connection effect of the steel pipe piles and the concrete strip foundation is enhanced, and the shear-resistant bearing capacity of connection is improved.
Preferably, the concrete strip foundation and the steel pipe pile are arranged in an orthogonal mode, so that the steel pipe pile is uniformly stressed, and unbalanced force caused by inclination of the concrete strip foundation is avoided.
Preferably, the concrete strip foundation is formed by open cut pouring so as to ensure the pouring quality of the strip foundation.
Preferably, the thickness of the filling soil on the concrete strip foundation is more than 0.5m, so that the concrete strip foundation is prevented from directly receiving the rainwater scouring effect, and carbonization and steel bar corrosion diseases of the concrete are reduced.
