Problems solved by technology

[0003] 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 is insufficient. As a result, it is difficult to determine the jacking position; the low structural strength will lead to a decrease in the safety of the jacking, which brings engineering difficulties to the jacking of ancient buildings

Embodiment Construction

[0040] For a better understanding and implementation of the invention, taking a certain ancient pavilion jacking project as an example, the overall jacking method for ancient buildings of the present invention is specifically described.

[0041] 1. Structural analysis of the ancient pavilion before it was lifted

[0042] 1. The ground of the Yuan Dynasty on which the ancient pavilion stands should have been higher than the groundwater level at that time in the Yuan Dynasty, and the water content should have been much lower than it is now, and its ground endurance should have met the requirements at that time. However, when the Yellow River silt buried the ground around the pavilion, the groundwater level rose accordingly and was higher than the surface in the Yuan Dynasty.

[0043] 2. According to the on-site survey, the underground water level of the site is relatively high, about 2.4-2.6 meters away from the current surface, which belongs to the type of pore diving. After t...

Abstract

The invention discloses an integral jacking method of heritage buildings. The method comprises six aspects of existing state reinforcement, precipitation, underpinning, jacking, monitoring and in-position repair, wherein during the underpinning, the measures of manufacturing tray beams, piling static pressure pile, casting fundamental apron piece and the like are used for constructing a substantial underpinning foundation for the jacking of the heritage buildings, so as to successfully realize the integral jacking of the heritage buildings with weak structure and foundation. The integral jacking method of heritage buildings has extremely important practical effect for saving and repairing the prior heritage buildings.

Description

Technical field [0001] The invention involves the repair and reinforcement technology of ancient buildings, and especially involves the overall top upgrade method of ancient buildings in ancient buildings. Background technique [0002] my country is an ancient civilization with a history of 5,000 years. In the process of history, generations of ancestors created rich and excellent buildings through their own wisdom and hard work.However, because the characteristics of Chinese buildings are not easy to retain for a long time and damage in war, these excellent ancient buildings can be retained very little.Even if the ancient buildings reserved, many of them have been crumbling due to the long -term natural erosion, and they are urgently waiting to be repaired. [0003] However, because the ancient buildings are mostly brick and wood structures, the structure strength is low, the overall stability is poor, and the foundation stiffness is insufficient. These defects need to be diffic...
