Deviation rectifying and strengthening structure for shallow-foundation building and construction method of deviation rectifying and strengthening structure

Abstract

The invention discloses a deviation rectifying and strengthening structure for a shallow-foundation building and a construction method of the deviation rectifying and strengthening structure for the shallow-foundation building. The deviation rectifying and strengthening structure comprises a pile bearing table, anchor rod static pressure piles, pile sealing plates and a filling layer. The pile bearing table is an original building shallow foundation obtained after building deviation rectifying or is formed by additionally arranging a foundation part on the original building shallow foundation obtained after building deviation rectifying. Pressure pile holes are formed in the upper surface of the pile bearing table, the static pressure piles are located in the pressure pile holes, and the pile tops of the static pressure piles are located in hole sections, located in the original building shallow foundation or pile bearing table, in the pressure pile holes. Concrete is poured in the pressure pile holes, anchor ribs are arranged on the pile tops of the anchor rod static pressure piles, and the anchor ribs are anchored in the concrete in the pressure pile holes. Pressure pile anchor rods penetrate in the bearing table from the upper surface of the bearing table and are located on the peripheries of the pressure pile holes, the upper ends of the pressure pile anchor rods are exposed out of the upper surface of the pile bearing table, and concrete is poured in the positions of the pressure pile holes so that the pressure pile anchor rods can be sealed into the concrete to form the pile sealing plates. By means of the deviation rectifying and strengthening structure for the shallow-foundation building and the construction method of the deviation rectifying and strengthening structure for the shallow-foundation building, when deviation rectifying treatment is conducted on the shallow-foundation building, the effect of strengthening the original foundation not meeting the requirement is achieved.

Description

technical field [0001] The invention belongs to the building structure correction and strengthening technology, in particular to a shallow foundation building deviation correction and reinforcement structure, which can reinforce the foundation of the building while correcting the shallow foundation building, and also relates to the shallow foundation building deviation correction and reinforcement method of construction of the structure. Background technique [0002] Some inclined buildings often have the problem that the foundation bearing capacity does not meet the requirements at the same time. Building deviation correction methods generally include excavation correction method, precipitation treatment method, surcharge pressure correction method and broken column jacking method, etc. [0003] The excavation correction method is to excavate part of the soil under the foundation on the side with the smaller settlement of the inclined building, causing the soil under the f...

AI Technical Summary

Problems solved by technology

The disadvantages of the above-mentioned several building deviation correction methods are: the first three deviation correction methods have a limited range of application, and they are all only dealing with the building tilt problem.

When the building is tilted and the bearing capacity of the foundation does not meet the requirements, none of the above three methods can solve the problems of the building tilt and the bearing capacity of the foundation at the same time; In the process of rectifying the deviation, the foundation of the building is reinforced, but this method needs to cut off the original structural column, the construction process is complicated and causes great damage to the original structure of the building
