Embodiment 1

[0052] The method for uplifting and reinforcing a subsidence building 1 with a cave 7 at the bottom in the background art is used for illustration. In this embodiment, the foundation soil at the bottom of the building includes backfilling earth and stone layers. A construction method for high-rise building settlement reinforcement and uplift correction, comprising the following construction steps:

[0053] Step 1, forming the curtain wall 3: as Figure 4 and Figure 5 As shown, holes are drilled vertically downward around the bottom plate 2 of the foundation of the building 1 to form a plurality of spaced curtain holes 31; the hole positions are about 2.0m to 2.7m away from the outer wall, and the hole spacing is 2.0m. The drilling depth is determined according to the geological survey data and in combination with the actual drilling conditions on site. Generally, the curtain hole 31 goes deep to 1m inside the bedrock layer 91. When there is a cave 7 directly below the curtai...

Embodiment 2

[0064] Such as figure 2 and image 3 As shown, half of the bottom plate 2 of the foundation of the building 1 is located in the excavation area, and half is located in the filling area, and the building 1 is settled on one side of the filling area. The method of strengthening and lifting includes the following construction steps:

[0065] Step 1. Forming the Curtain Wall 3: Combining Figure 8-Figure 10 , drill holes vertically downward around the base plate 2 of the building 1 foundation, and form a plurality of spaced curtain holes 31 in the filling area, and the curtain holes 31 go deep into the bottom of the filling. Then grouting in the curtain hole 31, the grouting range overlaps each other to form a U-shaped curtain wall 3, the curtain wall 3 encloses the backfill earth and stone layer below the base plate 2 of the building 1 foundation, and covers the building 1 range. Internal and external backfill earth and rocks are isolated. Preferably, the curtain hole 31 goe...

Embodiment 3

[0070] Such as Figure 11 and Figure 12As shown, most of the base plate 2 of the foundation of the building 1 is located in the excavation area, and only one corner is located in the filling area of ​​the existing river channel 10, and the settlement of the building 1 occurs only at this corner. In this case, it is only necessary to construct the curtain hole 31 on the two sides of the corner, and grout to form an L-shaped curtain wall 3 and to connect with the excavation area, and then perform grouting to the filling area below the base plate 2 Reinforcement; finally, a lifting grouting hole is constructed obliquely downward between the curtain wall 3 and the bottom plate 2 of the building 1, and the lifting pressure grouting is performed at the bottom of the reinforcement body 4.

Abstract

The invention relates to a construction method for high-rise building settlement reinforcement lifting deviation rectification. The construction method comprises the following steps that holes are vertically drilled downwards around a building bottom plate to form a plurality of curtain holes penetrating into foundation soil at intervals; grouting is conducted in the curtain holes, the grouting ranges are mutually meshed and overlapped to form a curtain wall, and the curtain wall encloses foundation soil below the bottom plate of the building foundation and isolates the foundation soil insideand outside the building range; a plurality of vertical reinforcing grouting holes are formed in the bottom plate, grouting is conducted, the soil body close to the bottom plate is completely reinforced, and a reinforcing body is formed; and downward drilling is conducted to form a lifting hole, the lifting hole goes deep into the bottom of the reinforcing body, pressure grouting is conducted on the bottom of the lifting hole, foundation soil is continuously filled and compacted along with continuous increase and rapid solidification of grout in the curtain wall, lifting force is formed, and the building is gradually lifted to the set lifting height. The construction method has the effects that the building can be effectively lifted, and secondary sedimentation can be prevented.

Description

technical field [0001] The invention relates to the technical field of uplifting deviation rectification and reinforcement of subsidence buildings, in particular to a construction method for uplifting deviation correction of high-rise building settlement reinforcement. Background technique [0002] Currently, if figure 1 As shown, a high-rise building 1 is a raft foundation, and below the raft foundation (that is, the floor 2 ) are a 50cm thick plain concrete layer 95 , a 5-6m thick rubble concrete layer 94 and a broken bedrock layer 91 . There are multiple small karst caves 7 in the broken bedrock layer 91 , the small karst caves 7 within the scope of the base plate 2 have been filled before the construction of the building 1 , but the peripheral karst caves 7 outside the scope of the base plate 2 have not been treated. During the construction of the building 1 , due to the gravity of the building 1 expanding outward in a trumpet shape, the surrounding karst caves 7 are sq...
