Embodiment Construction

[0040] The invention provides a method for adjusting and rectifying the load stress of a deep pile foundation building due to disaster damage and disease. According to the pile type, foundation soil quality and water level, number of floors, inclination and surrounding environmental conditions, the load stress adjustment and rectification method of the broken pile at the top of the pile can be selected. tilting method or pile side frictional stress regulation and rectification method.

[0041] 1. Adjustment and rectification method of pile load and stress at the pile top:

[0042] When the lower end of the pile is the bearing capacity provided by the supporting force of the rock, compact soil layer or pebble layer foundation (end-bearing pile or intermediate pile), the tilt correction operation should be adjusted first by the load stress of the broken pile at the top of the pile, or supplemented by pile side Method of rectifying tilt by adjusting frictional stress.

Abstract

The invention provides an inclination rectification reinforcing method for a disaster damage diseased deep pile foundation building. The inclination rectification reinforcing method comprises the following steps of selecting all piles or part of piles within a scope of a foundation of a building to be sunken to reversely incline; sequentially cutting the piles in different lengths based on the design requirements; connecting through a hydraulic jack and/or a steel plate pumping regulating device; gradually reversely inclining the building by regulating the device; or forcibly inclining the building to sink and reversely incline stably and slowly as the loading stress of the pile is increased by transferring bearing force of the cut broken pile on a retaining pile. The invention also provides an inclination rectification reinforcing method for a disaster damage diseased deep pile foundation building. With the adoption of the method, the bearing capacity of the pile is reduced by reducing the supporting friction resistance of the soil of the side foundation of some pile of the building so as to reversely incline the building to the side. The method can be applied to carrying out disaster resisting, disaster relieving and treating diseases to the deep pile foundation multi-rise or high-rise building based on common pile types.

Description

technical field [0001] The patent of the present invention relates to a method for rectifying the inclination of a building, in particular to a building with a common pile type deep pile foundation due to natural disasters such as earthquakes, floods, landslides, mud-rock flows, tsunamis, or mistakes in survey, design, and construction. It is the rectification method of the building when the building is tilted, excessive subsidence, crack damage, broken pile and other diseases. Background technique [0002] The buildings referred to in the present invention refer to public or civil office, commercial or residential buildings, and have prefabricated reinforced concrete piles, prestressed pipe piles, on-site concrete pouring piles, steel pipe piles, large-diameter Buildings based on single piles or group piles such as pipe columns or pipe piles, jet grouting piles, mixing piles, etc. Such as Figure 1a-Figure 1f As shown, they are reinforced concrete driving (or vibrating) pr...
