Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of building reinforcement, and particularly to a method for reinforcing anti-floating piles of waterfront buildings. Background Art
[0002] As a kind of anti-pulling pile, the anti-floating pile mainly bears tensile force, and its force size changes with the change of the groundwater level. In waterfront buildings, the main function of the anti-floating pile is to prevent the building from floating, tilting or being damaged due to the buoyancy of groundwater, and to ensure the safety and stability of the building.
[0003] After the anti-floating pile of a waterfront building is damaged, it needs to be reinforced. Traditional reinforcement methods for broken or damaged anti-floating piles mostly adopt methods such as increasing structural weights and anti-floating anchor cables. In the industry, the anti-floating anchor cable method is the mainstream for the reinforcement of broken or damaged anti-floating piles. This method refers to establishing an anchor cable with one end anchored in the building floor slab and the other end anchored in the bearing layer of the foundation to achieve the functions of anti-floating, reinforcing the foundation, reducing foundation deformation and uneven settlement. However, when using the anti-floating anchor cable method to reinforce the anti-floating pile, a large number of materials need to be prepared, and the process is complex, requiring processes such as anchor rod hole formation, anchor rod hoisting, and hoisting. There are many preparatory procedures in the early stage, and the construction steps are relatively complex. Summary of the Invention
[0004] The technical problem to be solved by the present invention is that in the prior art, when using the anti-floating anchor cable method to reinforce the damaged anti-floating pile, the process is complex and the construction steps are relatively cumbersome.
[0005] To solve the above technical problem, the present invention provides a method for reinforcing anti-floating piles of waterfront buildings, which includes the following steps:
[0006] Step S1: Build drainage outlets on both sides of the bearing platform, and pump out the accumulated water outside the anti-floating pile through the drainage outlets;
[0007] Step S2: After the accumulated water outside the anti-floating pile is drained, excavate the foundation pit downward and build a detection platform;
[0008] Step S3: After the detection platform is built, install a strain detection receiver on the detection platform. The strain detection receiver can obtain the horizontal height H1 from the bottom end of the bearing platform to the crack of the anti-floating pile, and build a construction platform. The horizontal height from the top end of the bearing platform to the construction platform is H2;
[0009] Step S4: After the construction platform is built, widen the bearing platform. At H1 below the bearing platform, remove the protective layer of the anti-floating pile, install a steel reinforcement cage, and connect the widened part of the bearing platform with the steel reinforcement cage of the anti-floating pile with steel bars;
[0010] Step S5: After the steel bars are welded, pour concrete above the construction platform according to the specified length, width and height to form a concrete block.
[0011] In one embodiment, in step S1, a water pump is used to pump out the accumulated water around the anti-floating pile.
[0012] In one embodiment, in step S1, the anti-floating pile includes a pile body and a protective layer arranged on the outer periphery of the pile body, and both the pile body and the protective layer are formed by casting concrete.
[0013] In one embodiment, in step S3, the horizontal height H1 from the bottom end of the bearing platform to the crack of the anti-floating pile and the horizontal height H2 from the top end of the bearing platform to the construction platform satisfy the relationship: H1≥4.5m, H2 = 5m or H1<4.5m, H2 = H1 + 2.5m.
[0014] In one embodiment, in step S4, the steel reinforcement cage is sleeved on the outer periphery of the anti-floating pile, and the steel reinforcement cage is used to fix the crack of the anti-floating pile.
[0015] In one embodiment, in step S5, during the process of pouring the concrete block, the protective layer of the anti-floating pile is replenished.
[0016] In one embodiment, in step S5, a strengthening member is arranged between the construction platform and the bearing platform to improve the strength of the concrete block.
[0017] In one embodiment, in step S5, after the foundation pit is filled, a pressure limiting valve is installed on the bottom plate of the bearing platform and a drainage pressure is set.
[0018] Further, in step S5, the length, width and height of the concrete block are calculated by the formula: N_float=(G_self + G_weight + T_anti - pull)×k, where N_float is known and represents the anti-floating bearing capacity required by the anti-floating pile. G_self is known and represents the self-weight above the bearing platform. T_anti - pull is known and represents the safety value after converting the original anti-floating bearing capacity. The method of calculating T_anti - pull is to multiply the anti-floating bearing capacity at the time of anti-floating pile design by a reduction coefficient, and the recommended value range is (0.5 - 0.7). G_weight is unknown and represents the weight of the concrete block to be designed and built. G_weight = ρVg. V uses length×width×h0. The length and width can be freely designed when they are greater than the length and width of the original bearing platform. k is a safety factor, and the recommended value range is (1.05 - 1.5), which is determined according to the importance of the building.
[0019] In one embodiment, drainage wells are respectively arranged on both sides of the bearing platform. The water inlet end of the pressure limiting valve is communicated with the foundation pit, and the other end is communicated with the drainage well, which is used to drain the accumulated water in the foundation pit higher than the local normal water level.
[0020] In one embodiment, the number of pressure limiting valves is multiple, and the multiple pressure limiting valves are wound around the outer periphery of the drainage well.
[0021] Compared with the prior art, the beneficial effects of the anti - floating pile reinforcement method for waterfront buildings in the embodiments of the present invention are as follows: 1) Cut the bottom plates on both sides of the bearing platform, construct drainage outlets, pump out the accumulated water outside the anti - floating piles through the drainage outlets, excavate the foundation pit downward, and construct a detection platform. Drain the accumulated water to prevent it from affecting the subsequent construction, ensure a dry working environment, and facilitate the implementation of subsequent steps. The excavation of the foundation pit provides space for subsequent construction, and the detection platform is used for subsequent monitoring of cracks in the anti - floating piles; 2) Install a strain detection receiver on the detection platform to obtain the horizontal height H1 from the bottom end of the bearing platform to the crack of the anti - floating pile, construct a construction platform, determine the horizontal height H2 from the top end of the bearing platform to the construction platform, accurately obtain the position of the crack of the anti - floating pile through the strain detection receiver, and at the same time establish a construction platform at the corresponding position in combination with the position of the crack of the anti - floating pile, providing a basis for subsequent reinforcement work; 3) After the construction platform is completed, remove the protective layer of the bearing platform and widen the bearing platform. At a position H1 below the bearing platform, remove the protective layer of the anti - floating pile and install a steel reinforcement cage. Connect the widened part of the bearing platform with the steel reinforcement cage using steel bars. After the steel bars are welded, pour concrete above the construction platform according to the specified length, width, and height to form a concrete block. Widen the bearing platform to increase its anti - floating bearing capacity. Through the steel reinforcement cage connecting the bearing platform and the anti - floating pile, enhance the structural connection between the two, improve the overall stability. By pouring concrete, a new structural part is formed, further enhancing the connection between the anti - floating pile and the bearing platform, and improving the overall anti - floating ability and stability.
[0022] In the embodiments of the present invention, through the design of anti - floating piles, concrete blocks, and bearing platforms, the anti - floating structure of the waterfront building forms an integral whole, effectively improving the anti - floating bearing capacity that the anti - floating piles can provide. At the same time, the cracks in the anti - floating piles are covered by the concrete blocks, reducing the vertical load pressure on the anti - floating piles. Brief Description of the Drawings

[0037] Embodiment 1
[0038] As Figures 1 to 4 and Figure 9 shown, the embodiment of the present invention preferably provides a method for reinforcing anti - floating piles of a waterside building, which includes the following steps:
[0039] Step S1: Construct drainage openings 11 on both sides of the bearing platform 1, and pump out the accumulated water outside the periphery of the anti - floating pile 2 through the drainage openings 11. Specifically, cut the bottom plates on both sides of the bearing platform 1, and use a water pump to drain the accumulated water to prevent it from affecting subsequent construction, ensuring a dry working environment for the implementation of subsequent steps.
[0040] Step S2: After the accumulated water outside the periphery of the anti - floating pile 2 is drained, excavate the foundation pit downward and construct a detection platform 3. The excavation of the foundation pit provides space for subsequent construction, and the detection platform 3 is used for subsequent monitoring of cracks in the anti - floating pile 2.
[0041] Step S3: After the detection platform 3 is constructed, install a strain detection receiver on the detection platform 3. The strain detection receiver can obtain the horizontal height H1 from the bottom end of the bearing platform to the crack of the anti - floating pile, and construct a construction platform 4. The horizontal height from the top end of the bearing platform to the construction platform is H2. Specifically, accurately obtain the position of the crack of the anti - floating pile 2 through the strain detection receiver, and at the same time, establish a construction platform 4 at the corresponding position in combination with the position of the crack of the anti - floating pile 2, providing a basis for subsequent reinforcement work.
[0042] Step S4: After the construction platform 4 is constructed, widen the bearing platform 1. At a position H1 below the bearing platform 1, remove the protective layer of the anti - floating pile 2, and connect the widened part of the bearing platform 1 with the steel reinforcement cage of the anti - floating pile 2 with steel bars. Widen the bearing platform 1 to increase its anti - floating bearing capacity, and enhance the structural connection between the two by connecting the steel reinforcement cage of the bearing platform 1 and the anti - floating pile 2, improving the overall stability.
[0043] Step S5: After the steel bars are welded, pour concrete above the construction platform 4 according to the specified length, width and height to form a concrete block 5. By pouring concrete, a new structural part is formed, further enhancing the connection between the anti - floating pile 2 and the bearing platform 1, and improving the overall anti - floating ability and stability.
[0044] As some embodiments of the present invention, as shown in the figure, in step S1, a water pump is used to pump out the accumulated water around the anti-floating pile 2. Using a water pump can quickly and effectively pump out the accumulated water, avoiding the adverse effects of the accumulated water on the construction process and structural stability. At the same time, after the accumulated water is pumped out, it provides a drier and safer working environment for subsequent construction steps such as foundation pit excavation, construction of the detection platform 3, and construction of the construction platform 4.
[0045] As some embodiments of the present invention, as Figure 1 shown, in step S1, the anti-floating pile 2 includes a pile body 21 and a protective layer 22 provided on the outer periphery of the pile body 21. Both the pile body 21 and the protective layer 22 are formed by concrete casting. Due to the high strength and durability of concrete, the anti-floating pile 2 can bear large vertical and horizontal loads, thus effectively resisting the buoyancy of groundwater.
[0046] As some embodiments of the present invention, as Figure 1 shown, the horizontal height H1 from the bottom end of the bearing platform 1 to the crack of the anti-floating pile 2 and the horizontal height H2 from the top end of the bearing platform 1 to the construction platform 4 satisfy the relational expression: H1≥4.5m, H2 = 5m. The horizontal height H1 from the bottom end of the bearing platform 1 to the crack of the anti-floating pile 2 ≥4.5m is regarded as the crack position of the anti-floating pile 2 being far from the bearing platform 1. At this time, the deep crack will significantly weaken the overall anti-floating bearing capacity of the pile body and reduce its mechanical properties such as compressive and flexural properties. Therefore, H2 is set to 5m.
[0047] As some embodiments of the present invention, as Figure 1 shown, in step S4, a steel reinforcement cage is sleeved on the outer periphery of the anti-floating pile 2 for fixing the crack of the anti-floating pile 2. The steel reinforcement cage can prevent the crack from further expanding, reduce the penetration of water and harmful substances, and thus extend the service life of the anti-floating pile 2.
[0048] As some embodiments of the present invention, as Figures 1 to 4 shown, in step S5, during the process of pouring the concrete block 5, the protective layer 22 of the anti-floating pile 2 is replenished. Replenishing the protective layer 22 of the anti-floating pile 2 is of great significance to the entire reinforcement project. It can not only prevent the anti-floating pile 2 from being eroded by the external environment and extend its service life, but also enhance the overall stability and safety of the structure and provide better support and protection for the upper structure.
[0049] As some embodiments of the present invention, as Figures 3 to 4 shown, in step S5, a strengthening member is provided between the construction platform 4 and the bearing platform 1 for improving the strength of the concrete block 5. In step S5, setting a strengthening member to improve the strength of the concrete block 5 is an effective reinforcement measure. This step can not only enhance the connection strength between the construction platform 4 and the widened part of the bearing platform 1, but also improve the anti-floating bearing capacity and anti-cracking performance of the entire building structure.
[0050] As some embodiments of the present invention, as Figure 9 shown, in step S5, after the foundation pit is filled, a pressure limiting valve 6 is installed on the bottom plate of the bearing platform 1, and the drainage pressure is set. By setting the pressure limiting valve 6, the set value of the pressure limiting valve 6 is adjusted to set an appropriate drainage pressure. This step aims to balance the relationship between the groundwater level and the safety of the building structure. When the counterweight of the concrete block 5 is small, the water level of the overall building structure is adjusted so that the water level of the building structure is set below the normal water level to ensure that the building structure does not float from the water surface.
[0051] As some embodiments of the present invention, as Figure 9 shown, drainage wells 7 are respectively arranged on both sides of the bearing platform 1. The water inlet end of the pressure limiting valve 6 is communicated with the foundation pit, and the other end is communicated with the drainage well 7, which is used to discharge the accumulated water in the foundation pit higher than the local normal water level. The design of the drainage well 7 and the pressure limiting valve 6 effectively avoids the situation that the water level is too high caused by local floods, etc., resulting in insufficient anti-floating bearing capacity provided by the building structure and the building structure floating. When the water level in the foundation pit is higher than the local normal water level, the pressure limiting valve 6 allows water to flow from the accumulated water in the foundation pit through its water inlet end into the drainage well 7, thereby realizing the drainage function, effectively reducing the water head in the foundation pit, discharging more water into the sump, and reducing the anti-floating bearing capacity required by the structure to achieve the purpose of balancing with the anti-floating bearing capacity.
[0052] As some embodiments of the present invention, as Figure 9 shown, the number of the pressure limiting valves 6 is multiple, and the multiple pressure limiting valves 6 are arranged around the outer periphery of the drainage well 7. When the multiple pressure limiting valves 6 are arranged around the outer periphery of the drainage well 7, they can more effectively disperse and control the pressure from the drainage system. This arrangement not only improves the overall safety of the system, but also helps to optimize the drainage efficiency and ensure the smooth flow of water. In addition, the use of multiple pressure limiting valves 6 can also provide redundancy, that is, if one pressure limiting valve 6 fails or malfunctions, the other pressure limiting valves 6 can still continue to work, thereby ensuring the continuity and reliability of the system.
[0053] Embodiment 2
[0054] As Figures 5 to 8 shown, on the other hand, the present invention provides a method for reinforcing anti-floating piles of a waterfront building, and the difference from Embodiment 1 is only that: the value of H1, H1 < 4.5m, H2 = H1 + 2.5m.
[0055] As some embodiments of the present invention, as shown in the figure, in step S3, the horizontal height H1 from the bottom end of the bearing platform 1 to the crack of the anti-floating pile 2 and the horizontal height H2 from the top end of the bearing platform 1 to the construction platform 4 satisfy the relationship: H1 < 4.5m, H2 = H1 + 2.5m. When the horizontal height H1 from the bottom end of the bearing platform 1 to the crack of the anti-floating pile 2 is < 4.5m, it is considered that the crack position of the anti-floating pile 2 is relatively close to the bearing platform 1. At this time, the crack of the anti-floating pile 2 has a relatively weak overall anti-floating bearing capacity for the pile body. Therefore, the horizontal height from the top end of the bearing platform 1 to the construction platform 4 is set to H2 = H1 + 2.5m. At the same time, the height of the concrete block 5 decreases as H2 decreases, on the premise of reducing the initial construction, to ensure that the anti-floating bearing capacity and anti-cracking performance of the building structure meet the requirements.
[0056] In summary, compared with the prior art, the anti-floating pile reinforcement method for a waterfront building provided by the embodiments of the present invention has the following beneficial effects: 1) Cut the bottom plates on both sides of the bearing platform 1, pump out the accumulated water outside the anti-floating pile 2 through the drain port 11, excavate the foundation pit downward, and construct the detection platform 3 to remove the accumulated water to prevent it from affecting the subsequent construction, ensure a dry working environment, and facilitate the implementation of subsequent steps. The excavation of the foundation pit provides space for subsequent construction, and the detection platform 3 is used for subsequent monitoring of the cracks of the anti-floating pile 2; 2) Install a strain detection receiver on the detection platform 3 to obtain the horizontal height H1 from the bottom end of the bearing platform 1 to the crack of the anti-floating pile 2, construct the construction platform 4, and determine the horizontal height H2 from the top end of the bearing platform 1 to the construction platform 4. The position of the crack of the anti-floating pile 2 can be accurately obtained through the strain detection receiver, and at the same time, the construction platform 4 at the corresponding position is established in combination with the position of the crack of the anti-floating pile 2, providing a basis for subsequent reinforcement work; 3) After the construction platform 4 is completed, remove the protective layer of the bearing platform 1 and widen the bearing platform 1. At a position H1 below the bearing platform 1, remove the protective layer of the anti-floating pile 2, connect the widened part of the bearing platform 1 with the steel cage of the anti-floating pile 2 with steel bars. After the steel bars are welded, pour concrete above the construction platform 4 according to the specified length, width and height to form the concrete block 5. Widen the bearing platform 1 to increase its anti-floating bearing capacity, enhance the structural connection between the two by connecting the steel cage of the bearing platform 1 and the anti-floating pile 2, improve the overall stability, and form a new structural part by pouring concrete, further enhancing the connection between the anti-floating pile 2 and the bearing platform 1 and improving the overall anti-floating ability and stability. In Embodiment 1 and Embodiment 2 of the present invention, through the design of the anti-floating pile 2, the concrete block 5 and the bearing platform 1, the anti-floating structure of the waterfront building forms a whole, effectively improving the anti-floating bearing capacity provided by the anti-floating pile 2. At the same time, the crack of the anti-floating pile 2 is covered by the concrete block 5, reducing the vertical load pressure on the anti-floating pile 2.
[0057] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can still be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
