Prefabricated ground and construction method

Abstract

The invention relates to a prefabricated ground. The prefabricated ground comprises a plurality of pile foundation assemblies arranged in a foundation and distributed in an array manner, main beams each erected between two corresponding adjacent pile foundation assemblies and a bottom plate supported on the main beams. Each pile foundation assembly comprises a preformed pile and a bearing table fixedly arranged at the upper end of the preformed pile. One aim of the prefabricated ground is to provide the prefabricated ground capable of increasing the engineering construction speed and quality. The prefabricated ground has the beneficial effects that the site construction speed of the prefabricated ground is high and is one few hundredth of the time needed for a conventional foundation treatment scheme, and therefore the investment recovery period is shortened, the overall cost input is reduced, and remarkable economic benefits are achieved; and deformation of the prefabricated ground in the using period is remarkably reduced relative to that of the conventional foundation treatment scheme, and the maintenance cost of house buildings in the using period can be reduced.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a prefabricated assembled floor and a construction method. Background technique [0002] my country's economically developed cities are mostly located in coastal soft soil areas, and soft soil foundation treatment is often required for large-scale construction. With the continuous development of my country's economy, the scale of construction is expanding day by day, and engineering construction also puts forward higher requirements for soft soil foundation treatment. For engineering construction on soft soil foundation, if effective reinforcement measures are not taken, the foundation will slip, crack or sink; if the foundation is not handled properly, it will easily cause the foundation to become unstable, causing excessive settlement or unevenness of the building Subsidence affects the safety of buildings. [0003] At present, the commonly used foundation treatment metho...

AI Technical Summary

Problems solved by technology

The thickness of soft soil in many areas is relatively large. Limited by the cost of foundation treatment, the post-construction settlement is often large, which affects the normal use of the project after completion, and may even cause project failure.
