Embodiment 1

[0034] Example 1: Please refer to figure 1 and figure 2 , the reinforcement pile 11 is a high-pressure rotary grouting composite pile, and the diameter of the reinforcement pile 11 located below the reinforced concrete slab of the building foundation is greater than the diameter above the bottom of the reinforced concrete slab of the building foundation, which is suitable for buildings that are more sensitive to settlement .

[0035] Preferably, the reinforcement pile 11 is poured with a high-strength self-compacting castable 15 under the reinforced concrete slab of the building foundation.

Embodiment 2

[0036] Example 2: Please refer to image 3 and Figure 4 , the reinforcement pile 11 adopts miniature piles, including tree root piles or steel pipe piles, the reinforcement pile 11 is arranged on the inner and outer sides of the reinforced concrete plate of the building foundation, and the reinforcement pile is located A reinforced concrete cap 16 connected to the building's basic structure planting bar is provided above the slab, which is suitable for buildings sensitive to settlement.

[0037] The construction method of the rectifying and strengthening structure of the inclined building specifically includes the following steps:

[0038]Step 1, laying pile holes penetrating through the reinforced concrete slab of the foundation of the building along the outline of the building on the inclined side of the building, and making reinforcement piles 11 in the pile holes to support the building;

[0039] Step 2: Arranging one or more rows of correction holes 12 inclined toward ...

Abstract

The invention relates to a rectification and reinforcement structure for an inclined building and a construction method thereof. The rectification and reinforcement structure for the inclined buildingcomprises a plurality of reinforcing piles which penetrate through a reinforced concrete slab of a foundation of a building on the inclined side of the building along the outline of the building andone or more rows of rectification holes formed in the opposite side of the inclined side of the building along the outline of the building. The rectification holes are formed by means of being inclined to the inner side of the foundation of the building. The direction of the rectification holes are corrected by a high-pressure jet machine in the rectification holes. The rectification holes are reinforced by high-pressure jet of cement slurry after high-pressure jet of high-pressure air-water on the foundation of the building and the elevation range below the foundation of the building. According to the rectification and reinforcement structure for the inclined building and the construction method thereof, the reinforcing piles are used for reinforcing the inclined side of the building, therectification holes are formed in the opposite side of the inclined side of the building, high-pressure air-water forced landing rectification technology is used for enabling the building to be subjected to rotating rectification by using the inclined side as the axis, and according to the monitoring data, the speed, rotating speed and air-water pressure of high-pressure jet machine are adjusteddynamically and informationally to punch and cut soil with any depth; and the construction is simple, efficient and easy to operate, the cycle is short, the structural safety of the building is not affected.

Description

technical field [0001] The invention relates to the technical field of building deflection correction, in particular to a deflection correction and reinforcement structure for an inclined building and a construction method thereof. Background technique [0002] In the process of building construction, foundation problems occur due to survey, design, construction, management errors, groundwater extraction, natural disasters, etc. Uniform settlement causes the structure of the building to tilt, and foundation problems mainly include: insufficient bearing capacity of the foundation, overall sliding damage or excessive settlement, damage to the foundation itself, and failure of the foundation especially under other special adverse geological conditions. [0003] Existing building deflection rectification methods mainly include the forced landing method, which uses technical measures on the opposite side of the building to increase its settlement to achieve the purpose of rectify...
