Multi-span height difference foundation slab structure and construction method thereof

Abstract

The invention discloses a multi-span height difference foundation slab structure and a construction method thereof. The multi-span height difference foundation slab structure comprises a first foundation slab, a second foundation slab, a third foundation slab, a fourth foundation slab and a fifth foundation slab, a first side wall is arranged between the second foundation bottom plate and the first foundation bottom plate, and the first side wall, the first foundation bottom plate and the second foundation bottom plate are integrally formed; a first basement outer wall and a second side wall are arranged between the third foundation slab and the second foundation slab; the second side wall and the second foundation slab are integrally formed; a third side wall is arranged between the fourth foundation slab and the first foundation slab, and a fourth side wall is arranged between the fourth foundation slab and the second foundation slab; the fourth foundation slab, the fourth side wall and the second foundation slab are integrally poured and formed; a second basement outer wall and a fifth side wall are arranged between the fifth foundation slab and the fourth foundation slab; and the fifth side wall and the fourth foundation slab are integrally formed. The technical problems that a foundation slab of a traditional foundation slab structure is large in hidden danger of water leakage, and construction procedures are increased are solved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a multi-span height difference foundation floor structure and a construction method thereof. Background technique [0002] Generally, the height difference of the basement base plate is small (within 2m), and the basement structure is constructed according to the basement exterior wall when the height of the basement structure is low. Backfill soil for exterior wall waterproofing and thermal insulation, build brick tire membrane, and finally construct high-span foundation floor. Considering the construction procedures of foundation floor waterproofing and exterior wall waterproofing and heat preservation, the construction process is added according to the high and low-span foundation floor, and the foundation floor is left in place. Construction joints will increase the hidden danger of water leakage at the base plate. SUMMARY OF THE INVENTION [0...
