Detailed description of the invention
Inventive feature and other correlated characteristic are described in further detail by embodiment below in conjunction with accompanying drawing, with
It is easy to the understanding of technical staff of the same trade:
As depicted in figs. 1 and 2, in figure, labelling 1-15 is respectively as follows: protection stake 1, stake roof panel 2, supporting device 3, settles spacing group
Part 4, building base plate 5, piling hole 6, spacing crossbeam 7, anchor pole 8, adjusting nut 9, steel column 10, correcting and then reinforcing device 11, former work
Journey stake 13, truncated position 14, former engineering pile 15.
Embodiment: as depicted in figs. 1 and 2, the present embodiment is specifically related to a kind of high-rise correcting and then reinforcing method, the party
Method specifically includes following steps:
(1) running through building base plate 5 and install multiple correcting and then reinforcing device 11, each correcting and then reinforcing device 11 interval is arranged in each former work
Between journey stake 13, correcting and then reinforcing device 11 includes protecting stake 1 and supporting device 3；Supporting device 3 one end is shored in described protection
The stake roof panel 2 at stake 1 top, its other end shores the upper surface at building base plate 5.
Concrete, building base plate 5 is installed correcting and then reinforcing device and comprises the following steps: open on building base plate 5
If piling hole 6；Protection stake 1 passes piling hole 6 soil layer plugged to building base plate 5, and the top of protection stake 1 is higher than
The upper surface of building base plate 5；Stake roof panel 2 is fixedly installed to protect the top of stake 1；At the bottom of stake roof panel 2 and building
Supporting device 3 is installed between plate 5.In the present embodiment, stake roof panel 2 is made up of girder steel, and stake roof panel 2 is by the way of welding
Install to protection stake 1.
Correcting and then reinforcing device 11 also includes settling limit assembly 4, and sedimentation limit assembly 4 is for by building base plate 5 and guarantor
Fender pile 1 is attached；Sedimentation limit assembly 4 includes spacing crossbeam 7 and at least two anchor poles 8, and the middle part of spacing crossbeam 7 is set up
Top in stake roof panel 2；Two anchor poles 8 are symmetricly set in the both sides of protection stake 1, and the upper end of anchor pole 8 is adjusted nut 9 and limit
Position crossbeam 7 connects, anchoring lower ends is in building base plate 5.The installation of sedimentation limit assembly 4 comprises the following steps: by two anchors
Bar 8 is the most vertically installed on the building base plate 5 of protection stake 1 both sides；Upper surface at stake roof panel 2 places steel column
10；The two ends of spacing crossbeam 7 are mounted respectively to two described anchor poles 8, and spacing crossbeam 7 is positioned at the top of a roof panel 2, spacing
Crossbeam 7 can be along anchor pole 8 vertical motion, and steel column 10 is positioned at the underface of spacing crossbeam 7；Install on the top of each anchor pole 8 and adjust
Joint nut 9, adjusting nut 9 can limit the maximum height of spacing crossbeam 7.
(2) being blocked by the former engineering pile of part 13 of less for building settlement side, former engineering pile 13 blocks rear building and exists
To the side sedimentation that sedimentation is less, thus reduce the gradient of building；Block in former engineering pile 13, block position and be positioned at building
Below thing base plate 5 at 1m ~ 2m, the length of the truncated position 14 of former engineering pile 13 is more than the settling amount of building.In order to ensure building
Thing uniform settlement, carries out interval for former engineering pile 13 and blocks, control the number of the former engineering pile 13 blocked in former work simultaneously
About the half of journey stake 13 total amount.
During building settlement, controlled the rate of settling of building by sedimentation limit assembly 4；At building settlement
During, the load that the former engineering pile 13 being truncated bears is transferred to protection by building base plate 5, anchor pole 8, spacing crossbeam 7
The top of stake 1；Now by the adjusting nut 9 at regulation anchor pole 8 top, the maximum height of spacing crossbeam 7 can be adjusted, and then adjust
The subsidence range of whole building and the rate of settling.Sedimentation limit assembly 4 is so that the infall process of building is in controlled
State, it is to avoid after building loses the support of the former engineering pile of part 13, building the most quickly sinks to causing structural deterioration.
In the present embodiment, rectifying of leaned building returns the predetermined value of speed of inclining is 1 mm ~ 3mm/d；Speed of inclining when rectifying a deviation back is little
When predetermined value, apply downward pressure to building base plate 5, by instead by supporting device 3 by the withdrawal resistance protecting stake 1
Pressure building base plate 5, forces former engineering pile to settle；Simultaneously can be by controlling the top near former engineering pile 13 side blocked respectively
Support arrangement 3 and near the supporting device 3 of former engineering pile 15 side not blocked, the respectively former engineering pile of increment control algorithm 9 and not blocking
The settling amount of former engineering pile 15；Rectify a deviation back using supporting device 3 to increase inclines during speed, and use settles limit assembly 4
Control the rate of settling of building, it is to avoid back-pressure building base plate 5 causes settling excessive.
Building settlement, to behind precalculated position, carries out grouting and reinforcing to the truncated position 14 of described former engineering pile 13, makes simultaneously
Carry out sealing stake to piling hole 6 and protection stake 1 with slightly expanded concrete, recover the integrity of each structure.
The advantage of the high-rise correcting and then reinforcing method of the present embodiment is: (1) sedimentation limit assembly 4 and protection stake make
After former engineering pile blocks, the load that former engineering pile undertakes effectively shifts, it is to avoid structure is suddenly, quickly sink, it is ensured that the peace of structure
Entirely；(2) supporting device 3 can carry out back-pressure to the former engineering pile not blocked, and actively realizes sedimentation regulation, is finally reached correcting and then reinforcing
