Description

Technical Field

[0001] This application relates to the technical field of building alignment correction, and in particular to a method for building alignment correction. Background Technology

[0002] Currently, most old buildings along streets are low-rise buildings, often less than 20 meters high. With the increasing number of historical and cultural preservation residential renovation projects under the background of urban renewal, the demand for protection and deformation control of low-rise and multi-story old buildings is increasing. Over time, old buildings often have insufficient foundation bearing capacity to support the weight of the building itself, resulting in building tilting. However, old buildings face complex surrounding environments and narrow construction spaces. In addition, due to their age, the structural performance of old buildings is not resilient enough. Therefore, in the process of correcting the tilt of a building, it is necessary to ensure the safety of the building itself and also to ensure that the surrounding area of ​​the building being corrected meets the requirements of low disturbance.

[0003] In the prior art, a column jacking method is disclosed. The column jacking method refers to taking appropriate measures to cut off the columns at the locations where settlement is more significant in a frame structure building that is tilting, based on the actual site conditions. These columns are actually the foundation piles used to support the building. Then, the columns are jacked up. After the displacement of the jacked column reaches the design requirements, the cut-off columns are reinforced and the jacking force is removed, thereby achieving the purpose of correcting the tilt.

[0004] However, while the column-breaking and lifting method can reinforce the foundation of a building during the process of correcting its deviation, it requires cutting off the original structural columns, which is a complex construction process and causes significant damage to the original structure of the building. Summary of the Invention

[0005] In order to reduce damage to the original structure of the building during the correction process, this application provides a building correction method that simplifies the correction process.

[0006] This application provides a method for correcting building alignment, which adopts the following technical solution:

[0007] A method for correcting building deviation includes the following construction steps:

[0008] S1: Excavate foundation pits around the building, and reserve foundation piers between the foundation pit sidewalls and the building;

[0009] S2: Install sensing equipment on the foundation platform, set up monitoring points, and calculate the deformation of the building;

[0010] S3: A steel pipe assembly is embedded at the bottom of the raft foundation. The steel pipe assembly includes several high-pressure water jet cutting devices. Water is pumped through the high-pressure water jet cutting devices. The water flows from the input end to the output end of the high-pressure water jet cutting devices and continuously flushes the soil.

[0011] S4: Take the steel cage and press it into the high-pressure water jet cutting device;

[0012] S5: Fill the steel cage with aggregate and pour concrete into the steel cage;

[0013] S6: Repair the surface of the first foundation and water it for maintenance.

[0014] By adopting the above-mentioned technical solution and installing sensing equipment, the settlement of the building can be monitored in real time, and the building's posture can be controlled. This data can be fed back to the operators, who can then quickly formulate a response plan based on the feedback. A high-pressure water jet cutting device is used to spray water onto the soil-flushing section, causing the soil in that section to break down. Some water seeps into the settlement adjustment section, and under the building's own weight, the building compresses the soil in the settlement adjustment section, causing that soil to deform and flow towards the soil-flushing section. This adjusts the differential settlement of the building, achieving the purpose of correcting the building's tilt. Furthermore, after completing the water-flushing correction process, the operators do not need to dismantle the steel pipe assembly, which remains within the underground foundation. This simplifies the construction process, reduces labor intensity, and effectively enhances the structural stability of the underground foundation, reducing the likelihood of subsequent building settlement and ensuring the quality of the project.

[0015] Preferably, the construction step S2 includes the following processing steps:

[0016] S2.1: Determine the actual deformation of the building, including the building's tilt direction, tilt displacement, settlement height, tilt angle, underground soil conditions, building's own structure, and surrounding structure.

[0017] S2.2: Delineate the correction foundation line of the building, calculate the soil storage volume between the strip foundation and the correction foundation line, or between the raft foundation and the correction foundation line, and set the soil storage volume as the correction inclined platform.

[0018] S2.3: Divide the correction platform into the soil flushing section and the settlement adjustment section.

[0019] By adopting the above technical solution, the actual deformation of the building can be monitored in real time, so that operators can make corresponding plans based on the feedback. At the same time, the correction platform is divided into two parts, and the mud output of the correction platform is monitored accordingly. This allows for better control of the building's correction, ensuring that the building is subjected to uniform force during the correction process and that the construction rate remains uniform. This achieves the effect of low disturbance and low space correction, and realizes the purpose of refined control and dynamic deformation recovery.

[0020] Preferably, the construction step S3 includes the following processing steps:

[0021] S3.1: The number of high-pressure water jet cutting devices increases with the amount of soil stored in the correction ramp.

[0022] By adopting the above technical solution, on the one hand, the steel pipe assembly can enhance the structural strength of the underground foundation. On the other hand, the water pumped by the high-pressure water jetting device at the settlement adjustment section permeates from top to bottom, thereby gradually softening the soil at the top of the slope of the settlement adjustment section and gradually flowing towards the scouring section, achieving the effect of slightly adjusting the differential settlement of the building, which helps to reduce damage to the original structure of the building.

[0023] Preferably, before carrying out the construction step of implanting the steel pipe assembly, a pile cap is first set at the bottom slab of the raft foundation, and two reinforcing steel pipe piles are taken and symmetrically implanted into the pile cap along the length direction of the support column of the raft foundation.

[0024] By adopting the above technical solutions, a pile cap is set at the bottom slab of the raft foundation and reinforcing steel pipe piles are added to the raft foundation, which effectively improves the connection stability between the raft foundation and the second foundation, thereby providing a solid foundation for the building and reducing the possibility of further settlement of the building.

[0025] Preferably, after the pile cap is installed, an L-shaped reinforcing bar is taken, with the long side of the reinforcing bar inserted into the top of the reinforcing steel pipe pile and the short side extending out of the reinforcing steel pipe pile.

[0026] By adopting the above technical solution, the long side of the reinforcing steel bar is inserted into the top of the reinforcing steel pipe pile and the short side extends out of the reinforcing steel pipe pile. On the one hand, it can effectively resist stress concentration in the concrete structure, reduce the generation and expansion of concrete cracks, and play a crack-resistant role; on the other hand, it can be closely connected with the concrete structure, enhancing the overall rigidity and stability of the structure.

[0027] Preferably, after the pile cap is installed, the limiter is removed and inserted into the pile cap. The limiter is used to limit the position of the reinforced steel pipe pile.

[0028] By adopting the above technical solution, the reinforcing steel pipe pile can be limited under the action of the limiter, which can further reinforce the reinforcing steel pipe pile, thereby improving the connection stability between the raft foundation and the second foundation.

[0029] Preferably, the construction step S3.1 includes the following processing steps:

[0030] S3.1.1: Pump water through a high-pressure water jetting device, monitor the water pressure inside the high-pressure water jetting device, and ensure that the water velocity inside the high-pressure water jetting device installed at the settlement adjustment section is less than the water velocity inside the high-pressure water jetting device installed at the soil flushing section.

[0031] S3.1.2: Monitor the soil flow direction in the settlement adjustment section to ensure that the soil at the top of the slope of the settlement adjustment section flows towards the scour section.

[0032] By adopting the above technical solution, during the correction process, the water velocity in the high-pressure water jetting device set at the settlement adjustment section is ensured to be lower than that in the high-pressure water jetting device set at the soil flushing section. This ensures that the correction ramp always drains mud and water from the soil flushing section. Under the action of the building's own weight, the building squeezes the soil in the settlement adjustment section, causing the soil in that part to deform and flow towards the soil flushing section. This slightly adjusts the differential settlement of the building, achieving the purpose of correcting the building's tilt. It also makes the flow direction of the soil more orderly and controllable, which can improve the safety of the operation to a certain extent.

[0033] Preferably, the construction step S3 includes the following processing steps:

[0034] S3.2: Set the angle between the inclined surface and the bottom surface of the correction platform to C. Calculate the amount of soil discharged by the correction platform and the angle C in real time until 1°<C≤3°, then stop flushing and correction.

[0035] By adopting the above technical solution, the angle between the inclined plane and the bottom of the correction platform is set to C, and the angle of the angle C is controlled. As the building is used for a longer period of time, the angle C will be naturally calibrated and disappear. By reserving the error, on the one hand, the difficulty of correcting the building can be reduced, thereby reducing the cost of manpower and materials. On the other hand, the correction angle of the building can be controlled within a controllable range, thereby meeting the needs of future settlement of the building and reducing the occurrence of disorderly settlement of the building to a certain extent.

[0036] Preferably, in the construction step S5, when filling the reinforcing cage with aggregate and pouring concrete, a section of aggregate is first filled into the reinforcing cage, the corresponding pipe wall is vibrated by a vibrator, and then concrete is poured into the reinforcing cage filled with aggregate.

[0037] By adopting the above technical solution, the vibration helps to eliminate gaps and air bubbles in the concrete inside the drainage pipe, thereby improving the density and uniformity of the concrete and ensuring the strength and stability of the overall structure.

[0038] Preferably, in the construction step S1, reinforcing piles are inserted into the foundation platform, with at least 1m of distance between the reinforcing piles and the outer wall of the building, and multiple reinforcing piles are arranged along the outer perimeter of the building.

[0039] By adopting the above technical solution and implanting reinforcing piles on the foundation platform, the interference of the building's correction process on surrounding buildings can be reduced, the first foundation can be reinforced, the structural rigidity of the foundation layer can be improved, and the building is less likely to settle too quickly or too much, which helps to reduce damage to the original structure of the building.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. By installing sensing equipment, the settlement of the building can be monitored in real time and the building's attitude can be controlled. This data can be fed back to the operators, who can then quickly formulate a response plan based on the feedback.

[0042] 2. High-pressure water jet cutting device is used to spray water onto the soil flushing section, causing the soil in the flushing section to break down. Some of the water seeps into the settlement adjustment section. Under the action of the building's own weight, the building squeezes the soil in the settlement adjustment section, causing the soil in that part to deform and flow towards the flushing section, thereby adjusting the differential settlement of the building and achieving the purpose of correcting the building's tilt.

[0043] 3. After completing the flushing and correction process, operators do not need to disassemble the steel pipe assembly, which remains within the second foundation. This simplifies the construction process, reduces labor intensity, and effectively enhances the structural stability of the second foundation, thereby reducing the likelihood of subsequent settlement of the building and ensuring project quality.

[0051] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0052] This application discloses a method for correcting building deviations.

[0053] Reference Figure 1 and Figure 2 In the existing technology, old buildings facing the street are low-rise buildings with shallow foundations 1. Due to considerations of construction costs, these buildings 1 often use raft foundations 11 as the foundation of building 1. The underground foundation piles of the raft foundation 11 are distributed, that is, the spacing between the piles is large. The weight of building 1 relies on the strip foundation or raft foundation 11 to transfer the load to the soil layer. Building 1 is greatly affected by changes in the surrounding environment, groundwater level, geological density, and disturbances from nearby construction. Building 1 will experience uneven settlement and tilt to one side. Therefore, the settlement of building 1 is positively correlated with the tilt angle of building 1.

[0054] In this application, the raft foundation 11 includes a base plate 111 and support columns 112. The support columns 112 are assembled on the base plate 111, and the base plate 111 presses against the underground foundation. The number of support columns 112 depends on the situation. Several support columns 112 are distributed at intervals within the raft foundation, which can divide the raft foundation 11 into several foundation units. A pile cap 12 is provided in the area between the bottom and top surfaces of the base plate 111. The pile cap 12 is used to reinforce the two corners around the connection between the base plate 111 and the support columns 112. Then, two reinforcing steel pipe piles 13 are taken and symmetrically inserted into the pile cap 12 along the length of the support columns 112, so that the reinforcing steel pipe piles 13 are connected between the pile cap 12 and the underground foundation.

[0055] Reference Figure 2 and Figure 3Take an L-shaped reinforcing bar 15, insert the long side of the reinforcing bar 15 into the top of the reinforcing steel pipe pile 13, and extend the short side out of the reinforcing steel pipe pile 13. The number of reinforcing bars 15 on each reinforcing steel pipe pile 13 depends on the situation, but ensure that the short side of the reinforcing bar 15 faces the end away from the central axis of the reinforcing steel pipe pile 13.

[0056] Take the limiter 14 and insert it into the pile cap 12. The number of limiters 14 is consistent with the number of reinforced steel pipe piles 13. The limiter 14 is used to limit the position of the reinforced steel pipe piles 13. Each limiter 14 includes two sets of fixed insert rods 141 and fixed reinforcing bars 142. The two sets of fixed insert rods 141 are symmetrically inserted into the bottom plate 111 of the raft foundation 11 along the length direction of the reinforced steel pipe piles 13. The two fixed insert rods 141 that are directly opposite each other are connected by a fixed reinforcing bar 142. That is, both ends of the fixed reinforcing bar 142 are tied to the two fixed insert rods 141 at the same time.

[0057] Reference Figure 2 and Figure 5 Concrete is poured into the pile cap 12 at the top surface of the base plate 111. The concrete fills the connection gap between the reinforced steel pipe pile 13 and the base plate 111, fills the top of the limiter 14, and fills the top of the reinforcing steel bar 15, effectively improving the installation stability of the reinforced steel pipe pile 13, thereby improving the connection stability between the raft foundation 11 and the second foundation 42.

[0058] In this application, building 1 is constructed on raft foundation 11, and the underground foundation is divided into a first foundation 41 and a second foundation 42. The portion above the raft foundation 11 is the first foundation 41, that is, the area of ​​building 1 close to the ground, and the portion below the raft foundation 11 is the second foundation 42.

[0059] A method for correcting building deviation includes the following construction steps:

[0060] Reference Figure 4 and Figure 5 S1: Determine the location of building 1, mark the construction range of the foundation pit on the first foundation 41, reserve a foundation platform between the side wall of the foundation pit and building 1, ensure that the foundation platform is large enough to ensure the stability of the underground foundation around building 1, reduce the disturbance to the internal and external buildings 1 caused by subsequent correction construction, and at the same time ensure the construction space for operators in the foundation pit.

[0061] In this embodiment of the application, multiple reinforcing piles (not shown in the figure) are used. The reinforcing piles are used as sealing pile plates. The reinforcing piles are vertically inserted into the foundation cap. There is at least a 1m distance between the reinforcing piles and the outer wall of the building 1. The multiple reinforcing piles are arranged along the outer perimeter of the building 1 until the building 1 is surrounded. The top of the reinforcing piles extends out of the top of the foundation cap. The reinforcing piles are used to separate the building 1. Construction personnel are strictly prohibited from entering the interior of the building 1 during the correction process.

[0062] S2: Install sensing equipment on the foundation platform, set up monitoring points, and calculate the deformation of building 1.

[0063] S2.1: Determine the actual deformation of Building 1, including the building's tilt direction, tilt displacement, settlement height, tilt angle, underground soil conditions, the building's own structure, and the surrounding structure.

[0064] S2.2: Delineate the correction foundation line of building 1 and calculate the amount of soil to be stored between the raft foundation 11 and the correction foundation line.

[0065] Specifically, after the building 1 tilts, the second foundation 42 surface, which is parallel to the raft foundation 11, forms a right-angled triangle or right-angled trapezoid as the inclined surface. The amount of soil stored in this part is set as the correction platform 5, so that the entire correction platform 5 is located at the bottom of the raft foundation 11.

[0066] S2.3: Divide the correction platform 5 into a soil flushing section 51 and a settlement adjustment section 52. The soil flushing section 51 is located on the side of building 1 with greater settlement, and the settlement adjustment section 52 is located on the side of building 1 with less settlement.

[0067] Operators monitor the actual soil volume of the correction platform 5 in real time using sensing equipment. Based on the actual soil volume of the correction platform 5, they calculate the building tilt direction, building 1 tilt displacement, building 1 settlement height, and building 1 tilt angle, and generate a data table. Once the deformation value exceeds the allowable error, the correction construction is stopped immediately.

[0068] Reference Figure 4 and Figure 6 S3: A steel pipe assembly is implanted at the bottom of the raft foundation 11, and the output end of the steel pipe assembly is aligned with the soil flushing part 51 and the settlement adjustment part 52 of the correction inclined platform 5.

[0069] S3.1: The steel pipe assembly includes several high-pressure water jet cutting devices 61. The number of high-pressure water jet cutting devices 61 increases with the amount of soil stored in the correction inclined platform 5. That is, the number of high-pressure water jet cutting devices 61 set at the settlement adjustment section 52 is greater than the number of high-pressure water jet cutting devices 61 set at the soil flushing section 51. In this application, water is pumped by the high-pressure water jet cutting devices 61. The water flows from the input end to the output end of the high-pressure water jet cutting devices 61 and continuously flushes the soil flushing section 51 and the settlement adjustment section 52, so that a vacuum environment is formed around the output end of the high-pressure water jet cutting devices 61, causing the stress of the foundation soil of the inclined building 1 to be relieved, thereby causing the soil to undergo plastic flow.

[0070] S3.1.1: Pump water through the high-pressure water jetting device 61, monitor the water pressure inside the high-pressure water jetting device 61, and ensure that the water velocity inside the high-pressure water jetting device 61 located at the settlement adjustment section 52 is less than the water velocity inside the high-pressure water jetting device 61 located at the soil flushing section 51.

[0071] S3.1.2: Monitor the soil flow direction in the settlement adjustment section 52 to ensure that the soil at the top of the slope of the settlement adjustment section 52 flows towards the soil scouring section 51.

[0072] To prevent the steel pipe assembly from deforming due to pressure from the underground foundation, the operator can quickly impact the scouring section 51 by adjusting the water flow speed according to the actual underground foundation conditions, thereby disrupting the soil structure of the scouring section 51 and improving its disintegration effect. At the same time, the water pumped by the high-pressure water cutting jetting device 61 at the settlement adjustment section 52 permeates from top to bottom, gradually softening the soil at the top of the slope of the settlement adjustment section 52. Under the weight of the building 1, the building 1 compresses the soil in the settlement adjustment section 52, causing the soil in this part to deform and flow towards the scouring section 51.

[0073] Reference Figure 6 S3.2: Set the angle between the inclined surface and the bottom surface of the correction platform 5 to C, calculate the amount of soil discharged by the correction platform 5 and the angle C in real time, and stop flushing correction when 1°<C≤3°.

[0074] As building 1 is used for a longer period of time, the included angle C will be naturally calibrated and disappear. By reserving the error, the difficulty of correcting the deviation of building 1 can be reduced, thereby reducing the cost of manpower and materials. Furthermore, the deviation angle of building 1 can be controlled within a controllable range, thereby meeting the needs of future settlement of building 1 and reducing the occurrence of disorderly settlement of building 1.

[0075] S4: Take the steel cage and press it into the high-pressure water jet cutting device 61, so that the entire high-pressure water jet cutting device 61 is tightly wrapped with the steel cage, effectively enhancing the structural rigidity of the pipeline.

[0076] S5: Fill the steel cage with aggregate and pour concrete into the steel cage.

[0077] When filling the reinforcing cage with aggregate and pouring concrete, first fill a section of aggregate into the reinforcing cage, then vibrate the corresponding pipe wall with a vibrator, and then pour concrete into the reinforcing cage filled with aggregate. Continue to vibrate the corresponding pipe wall with a vibrator until the concrete flows out of the pipe hole and fills the gaps around the pipe. Monitor the condition inside the pipe. When there is no floating slurry and no air bubbles in the pipe, wait for the concrete in that section of the reinforcing cage to harden, and repeat the construction steps of filling aggregate and pouring concrete until the entire pipe is solidified.

[0078] By moving the material upwards point by point and vibrating it thoroughly, the gaps between the materials can be reduced, the density of the materials can be improved, and the structural rigidity of the high-pressure water jet cutting device 61 can be increased.

[0079] Compared with the existing raft foundation 11 building correction technology, it reduces the phenomenon of continuous correction after the completion of the building 1 correction, ensures the quality of the project, and improves the service life of the building 1. Compared with the existing non-raft foundation 11 building correction technology, it realizes the correction function of large offset angle, and the correction process will not interfere with the dense underground foundation piles, making it easier for construction personnel to operate and helping to speed up the construction efficiency.

[0080] S6: Repair the surface of the first foundation 41 and water it for maintenance.

[0081] Monitor the curing status of the steel pipe assembly. Once the steel pipe assembly reaches the curing standard, remove the reinforcing piles and use filler to seal the holes corresponding to the reinforcing piles.

[0082] A leveling layer 411 is laid on the top surface of the first foundation 41. Specifically, a leveling material is prepared by mixing an appropriate amount of sand, cement and gravel. The leveling material is spread evenly on the top surface of the first foundation 41. The leveling layer 411 is allowed to harden, and its surface is polished and watered for curing.

[0083] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
