Embodiment

[0050] There is an ancient building with masonry structure. After investigation, it is determined that its foundation is a soft soil gravel foundation that has been simply treated. Due to the poor integrity of the foundation, the building has undergone slight uneven settlement after being affected by groundwater erosion and stratum movement for a long time. Caused the east side of the building to sink by 10cm. If the foundation reinforcement and deviation correction are not carried out in time, it will cause irreparable damage to the upper ancient buildings.

[0051] After measurement, the size of the ancient building is: 8m×5m×6m; the load of the superstructure is: 5000KN; the depth of the foundation is: 2m; The size is: 1.3m×5.5m×0.3m. Temporary protective structures shall be set up for the superstructure before construction.

[0052] 1. Excavate a construction pilot pit on the surface soil 3 around the building, and the depth of the pilot pit is 2.3m. Assemble a horizont...

Abstract

A method of horizontal foundation replacement combined with pile jacking, reinforcement, and deviation correction, which belongs to the field of foundation reinforcement and deviation correction, can solve the problems of foundation reinforcement and deviation correction of ancient buildings on poor integrity, broken and loose foundations, and excavates pilot pits around the building. Excavate the original foundation of the building horizontally in the pilot pit, replace it with prefabricated reinforced concrete slabs, and finally use tensioning screws to tighten multiple prefabricated reinforced concrete slabs, and set ring beams around them. Finally, the weak and broken original foundation was replaced with a complete reinforced concrete slab foundation. Just below the new foundation, jacks are set to push down the steel pipe piles section by section to stabilize the rock formation, correct the uneven settlement and building inclination, and finally complete the foundation replacement and reinforcement and correction of the inclined ancient buildings with uneven settlement. The invention has fast construction speed, requires less manpower and material resources, and has less disturbance to the superstructure and is safer, and the integrity and stability of the reinforced concrete slab foundation after the final replacement are higher than other replacement methods.

Description

technical field [0001] The invention belongs to the technical field of foundation reinforcement and deviation correction, and in particular relates to a method for horizontal foundation replacement combined with pile jacking, reinforcement and deviation correction. Background technique [0002] In the history of our country for more than 5,000 years, countless skilled craftsmen have left ancient buildings on the vast land of our country that can fully reflect the architectural level, customs, and religious etiquette. These ancient buildings are priceless treasures of our country. However, limited by the backward construction level in ancient times, many ancient buildings are directly built on the ground of crushed stones and rammed earth which is simply handled. Sex and carrying capacity are relatively poor. Under the disturbance of underground seepage, weathering, stratum movement, and surrounding building construction, the foundation is not uniformly stressed, and if thin...
