Inverted construction method and structure of bearing platform and base plate of basement under current-formed soils

Abstract

The invention discloses an inverted construction method and structure of a bearing platform and a base plate of a basement under current-formed soils. The inverted construction method includes that earth excavation of a foundation pit is a one-time excavation, the foundation pit is excavated and 5cm-50cm lower than an elevation position of the bottom surface of the bearing platform, a plain concrete cushion layer and a waterproof layer are sequentially constructed at the bottom of the foundation pit, position of the waterproof is at the elevation position of the bottom surface of the bearing platform, then the base plate and the bearing platform are constructed on the waterproof layers, and filling materials are filled in gaps in the bearing platform. The inverted construction method and structure is convenient to construct, safe and rapid and free of a brick molding die and a pit in a pit. The base plate is integrated with the bearing platform, so that strength of the bearing platform is greatly strengthened. The plain concrete cushion layer and the waterproof layer are convenient to construct and assemble and in a same plane, thereby achieving guaranteed waterproof effect. Concrete blocks supported in broken reinforced concrete are recycled and backfilled in the gaps in the bearing platform to construct a water filtering layer, thus saved materials, energy saving and environmental protection are achieved.

Description

technical field [0001] The invention relates to an inverted construction process and structure of a basement platform under flow-plastic soil quality, and belongs to the technical field of foundation construction technology. Background technique [0002] With the acceleration of urbanization and the decrease of land resources, human needs and dependence on underground space are becoming stronger and stronger, and the corresponding building foundations are getting deeper and deeper. The difficulty is getting higher and higher. Generally, grading or masonry brick molds are used. However, grading under the flow-plastic soil is prone to landslides and lead to rework, and the construction progress is slow, which seriously affects the construction progress of the entire floor. The flow-plastic soil The lower brick formwork is also prone to collapse, and the backfill of the backside soil of the brick formwork is easy to squeeze the brick formwork and cause collapse, which also s...
