Inclination rectification reinforcing method for disaster damage diseased deep pile foundation building

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...

Problems solved by technology

[0008] ⑷ If cheating, cutting corners and poor quality are used during construction, it will cause damage to the pile foundation; if Figure 5a-5c As shown, it means that the slag in the hole is not completely cleaned during the construction of the cast-in-situ pile, so that the pile tip does not act on the bearing layer, and some piles fall on the boulder in the soil during the construction of the driven pile or the pressed pile, and there is a virtual soil layer under the boulder , Excessive speed of pipe extraction of immersed pipe grouting piles leads to necking damage of pile foundation
