Abstract

The invention discloses a building pile foundation protection method. The method comprises the following steps of adopting manual excavation at the position of tunnel excavation close to the buildingpile foundation to expose part of the surface of an existing pile foundation; after the surface of the pile foundation is exposed, designing a special-shaped steel plate according to the pile foundation to ensure that the special-shaped steel plate is attached to the surface of the pile foundation; drilling an anchor hole on the special-shaped steel plate; installing the special-shaped steel plateon the pile foundation, correcting the position of the special-shaped steel plate, and filling and grouting between the special-shaped steel plate and the pile foundation; after the maintenance period, mounting an anchor cable in the anchor hole, and performing prestress tensioning; and chiseling rock soil except the pile foundation layer by layer from top to bottom, and installing special-shapedsteel plates and tensioning anchor cables step by step according to the steps. The building pile foundation protection method does not damage existing limit-invading building pile foundations, ensures the safety of the upper building structure of the pile foundation, adopts the special-shaped steel plate and prestressed anchor cables, has simple structure, clear stress and convenient construction, adopts a mode of excavating step by step and supporting simultaneously, and avoids the structure from being in an unfavorable stress state in the construction process.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a method for protecting pile foundations of buildings. Background technique [0002] For many years, my country's urban development has followed the extensive model of extension and centrifugal, and the degree of urban land use intensification is relatively low. With the rapid increase of urban population, cars have gradually become a popular means of transportation, and a series of "urban diseases" such as space congestion, traffic jams, and environmental degradation have emerged. In order to build a pedestrian-friendly city, the voice of "transferring traffic to the ground and returning green to the people" is getting louder and louder. With the increasing shortage of urban resources, the three-dimensional, intensified and high-density development of urban space is also the general trend. Especially in some urban core areas and urban built-up areas, there is not m...
