Ancient building overall-jacking method,

Abstract

The invention provides an ancient building overall-jacking method, and relates to the technical field of restoration and reinforcement of ancient buildings. The ancient building overall-jacking methodaims to solve the problems that when a jacking method in the prior art is used for an ancient building along a river, construction is inconvenient, and the cost is high. The ancient building overall-jacking method comprises the following steps that S1, an ancient building body is reinforced; S2, a cofferdam is constructed, and a foundation pit is excavated; S3, a foundation wall is reinforced; S4, supporting piles are inserted, an annular steel frame is placed; S5, a steel plate is arranged at the bottom of the foundation wall in a padded mode; S6, a jack is arranged between the steel plate and the annular steel frame for pre-jacking; S7, a prefabricated bearing platform is connected in an inserted mode; and S8, a new jack is arranged between the bearing platform and the steel plate, thejack between the annular steel frame and the steel plate is adjusted, and jacking is completed. According to the ancient building overall-jacking method, by arranging the supporting piles, the annularframe and the steel plate and additionally arranging hoisting equipment, pre-jacking is conducted, and thus the ancient building is lifted preliminarily; and then the prefabricated bearing platform is inserted transversely into the foundation pit, thus the ancient building along the river is stably jacked, construction is convenient, and the cost of the ancient building overall-jacking method islow.

Description

technical field [0001] The invention relates to the technical field of restoration and reinforcement of ancient buildings, in particular to an overall jacking method for ancient buildings. 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 rich and excellent buildings of all kinds through their own wisdom and hard work. However, due to the difficulty of long-term preservation of the brick and wood structure of Chinese buildings and the destruction caused by wars, very few of these excellent ancient buildings can be preserved. Even the preserved ancient buildings, due to long-term natural erosion, many have reached the point where they are crumbling and urgently need to be repaired. However, due to the fact that 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 i...

Problems solved by technology

[0004] This overall lifting method of ancient buildings can be applied to the restoration and reinforcement of most ancient buildings. However, in the southern region with a relatively developed water conservancy network, especially the ancient towns in the south of the Yangtze River, some ancient buildings are built along the river, and part of the foundations of the ancient buildings are located in the south of the Yangtze River. Below the water surface, although the integrated foundation facilitates the subsequent jacking operation, the foundation set below the water surface brings inconvenience to the pouring of the jacking device and the prefabricated cap, the construction is difficult and the operation cost is high, resulting in It is difficult to repair the ancient buildings along the river by the overall jacking method of some ancient buildings. Therefore, there is an urgent need for a jacking method that can be applied to the ancient buildings along the river.
