A kind of integral jacking method of ancient buildings

Abstract

The invention discloses an integral lifting method for an ancient building. The technical scheme is characterized in that (1) the ancient building is reinforced; (2) a foundation of the ancient building is underpinned; (3) the ancient building is lifted integrally. The method comprises the following steps: arranging a plurality of jacks which are distributed on a foundation apron piece in a matrix form along the width direction of the ancient building into one group in sequence; arranging a plurality of groups of the jacks along the length direction of the ancient building; during first lifting, reducing the lifting heights of the plurality of groups of jacks in sequence from left to right along the length direction of the ancient building; during second lifting, reducing the lifting heights of the plurality of groups of jacks in sequence from right to left along the length direction of the ancient building, wherein the highest point during the first lifting is the lowest point during the second lifting; lifting the ancient building by the first lifting and the second lifting alternatively in sequence. By adopting the integral lifting method for the ancient building, high lifting efficiency and a stable structure are realized, and damage to the ancient building is prevented.

Description

technical field [0001] The invention relates to ancient building repair and reinforcement technology, more specifically, it relates to an ancient building overall jacking method. Background technique [0002] my country is an ancient civilization with a history of 5,000 years. In the course of history, generations of ancestors have created a variety of buildings through their own wisdom and hard work. However, due to the characteristics of brick and wood structures in Chinese buildings, it is not easy to preserve them for a long time. As well as war damage and other reasons, very few of these excellent ancient buildings can be preserved. Even if the preserved ancient buildings, due to long-term natural erosion, many of them have reached the point where they are crumbling and need to be repaired urgently. [0003] Because most of the ancient buildings are of brick and wood structure, the structural strength is low, the overall stability is poor, and the foundation rigidity is ...

AI Technical Summary

Problems solved by technology

[0003] Because most of the ancient buildings are of brick and wood structure, the structural strength is low, the overall stability is poor, and the foundation rigidity is not enough. It is difficult to determine the jacking position; the low structural strength leads to a decrease in the safety of the jacking, which brings engineering difficulties to the jacking of ancient buildings, and ancient buildings are excellent protected buildings, which requires maintaining their original The architectural style, structure and function will not be changed by any damage
