AI Technical Summary

Technical Problem

In existing technologies, a reinforced concrete outer wall still needs to be set between the foundation pit support structure and the structural infill wall, resulting in duplicated load-bearing functions and wasted project investment.

Method used

The foundation pit support structure is fixedly connected to the floor slab to form a cavity, and a drainage system is set at the bottom of the cavity. The traditional reinforced concrete exterior wall is eliminated. The foundation pit support structure undertakes the function of retaining soil and stopping water, while the structural infill wall undertakes the function of partitioning.

Benefits of technology

It achieves functional decoupling, reduces material usage and construction difficulty, ensures a dry basement space, and features a simple structure, economical cost, and reliable waterproofing.

Abstract

The basement structure comprises a foundation pit supporting structure configured to be arranged continuously along a foundation pit edge for retaining soil and water, each floor slab of the basement is connected with the foundation pit supporting structure; a structural filling wall configured to be arranged between adjacent floor slabs; and a cavity located between the foundation pit supporting structure and the structural filling wall, the cavity being jointly defined by the foundation pit supporting structure, the structural filling wall and the floor slabs, and a drainage system being arranged at the bottom of the cavity. The basement structure of the present application cancels the traditional basement reinforced concrete outer wall, forms an effective structural force transmission path through the fixed connection of the foundation pit supporting structure and each floor slab, ensures the force reliability of the whole system, thereby bearing the retaining soil and water function by the foundation pit supporting structure and bearing the indoor partition function by the light structural filling wall, realizes the function decoupling, and greatly reduces the material consumption and construction difficulty.
