Semi-prefabricated underground continuous wall and construction method thereof
The invention discloses a semi-prefabricated underground continuous wall and a construction method thereof. The continuous wall comprises a lower prefabricated wall and an upper post-poured wall. The lower prefabricated wall comprises a plurality of prefabricated wall sections; a connecting rib is arranged at the tops of the prefabricated wall sections; the adjacent prefabricated wall sections are connected by use of a steel pipe joint, and a plurality of through holes are formed in the wall, connected with the prefabricated sections, of the steel pipe joint. The upper post-poured wall is a cast-in-place reinforced concrete structure; a spiral stirrup is vertically arranged in the middle of the reinforcement cage of the upper post-poured wall; the part, exceeding the prefabricated wall sections, of the steel joint is arranged in the spiral stirrup; the reinforcement cage is connected and fixed with the connecting rib. The semi-prefabricated underground continuous wall is integrated with the advantages of the cast-in-place underground continuous wall and the prefabricated underground continuous wall, and the easily occurring defects of the cast-in-place underground continuous wall and the prefabricated underground continuous wall can be avoided reasonably. The lower part of each wall section is the prefabricated wall section, and therefore, the construction difficulty of the continuous wall is greatly reduced and the construction quality of the continuous wall is easy to guarantee.
