Internal support system and basement structure system three-in-one method for foundation pit supporting

Abstract

The invention provides an internal support system and basement structure system three-in-one method for foundation pit supporting, and belongs to the technical field of building construction. According to the internal support system and basement structure system three-in-one method for foundation pit supporting, an enclosing pile wall, a horizontal internal support and vertical pillar piles used for foundation pit supporting are constructed in the excavation stage of a foundation pit; and after excavation of the foundation pit is completed, the enclosing pile wall, the horizontal internal support and the vertical pillar piles separately act on a basement structure external wall, a basement structure floor and basement structure columns, so that an internal support system and a basement structure system for foundation pit supporting are combined. By adoption of the internal support system and basement structure system three-in-one method for foundation pit supporting, the problems thatan existing temporary internal supporting horizontal structure and stand columns need to be removed and an enclosing pile wall for foundation pit supporting is discarded after construction, and consequentially, labor consumption and material consumption are high, a large quantity of construction waste is generated, resources are severely wasted, environmental friendliness cannot be achieved, and the construction period is prolonged are solved.

Description

Technical field [0001] The invention relates to a three-in-one method for a foundation pit supporting internal support system and a basement structural system, and belongs to the technical field of building construction. Background technique [0002] Nowadays, urban construction land is tight. Many plots between buildings and structures have been used, or the old areas in the city have been renovated. The surrounding areas of these places have been built. The basement of the new building has many floors and the foundation is excavated. When pit, the foundation pit is very deep, but the method of anchoring outside the foundation pit cannot be used. Generally, the method of internal support is adopted, such as occlusal pile + internal technical support, underground continuous wall + internal technical support, etc. Pit supporting methods. These supporting systems include supporting pile wall structures, horizontal supporting structures, columns, etc., and most of these are concrete...

AI Technical Summary

Problems solved by technology

[0003] The invention provides a three-in-one method of foundation pit support internal support system and basement structure system to solve the problem that the existing internal support temporary horizontal structure and columns need to be chiseled after construction and the pile wall structure of foundation pit support is damaged. Abandonment will consume a lot of manpower and material resources, and generate a lot of construction waste, which is not only a waste of resources, but also not environmentally friendly, and it also prolongs the construction period.
