Reinforcing method and reinforcing structure for replacing strip foundations by raft foundations

Abstract

The invention discloses a reinforcing method and a reinforcing structure for replacing strip foundations by raft foundations. The reinforcing method comprises the following steps of: (1) excavating two foundation pits in the grounds on two sides of each of the strip foundations correspondingly; (2) in each strip foundation, scooping out a plurality of holes which are successively arranged at intervals along the length direction of each of the strip foundations; (3) putting a bound cantilever beam reinforcement cage in each of the holes; (4) putting two bound boundary beam reinforcement cages in the foundation pits on two sides of each of the strip foundations correspondingly; (5) binding bottom plate basic reinforcing steel bars between the two boundary beam reinforcement cages between every two strip foundations; and (6) pouring concrete into the holes and the foundation pits. The reinforcing method plays a hooping role to the original strip foundations, the original structure is not damaged during construction, reinforcement equal to increase of the cross section is performed on the original structure, and the formed raft foundations more effectively bear an upper load.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a reinforcement method and a reinforcement structure for a strip foundation. Background technique [0002] Due to the needs of social development, some major national projects and urban planning projects that are related to people's livelihood and the environment have conflicts with existing buildings during construction, and some ancient buildings with a long history are unique and uninhabitable. At present, my country has strengthened the protection of these buildings. In addition, in civil buildings and industrial buildings at present, due to the change of the function of the building, the increase of the bearing capacity and other reasons, the original building needs to be reinforced to meet the requirements of use. The foundation is the load-bearing component below the ground of the building. All the loads passed down from the superstructure of the building are transfer...

AI Technical Summary

Problems solved by technology

When anchor static pressure piles are used for reinforcement, the strength of the foundation is increased, so that the original strip foundation is reinforced. This reinforcement method does not increase the strength of the strip foundation. This reinforcement method is used when the strength of the strip foundation is seriously insufficient. Easy to generate side pressure with a certain degree of danger
