Description

Technical Field

[0001] This utility model relates to the field of foundation construction technology, specifically a pile for reinforcing settlement foundations. Background Technology

[0002] In construction engineering, the stability of the foundation directly affects the safety and service life of the entire building. However, due to complex and variable geological conditions, especially in areas with soft soil foundations or prone to settlement, traditional foundation treatment methods often fail to meet the requirements for long-term stability. Traditional foundation reinforcement methods, such as replacement and dynamic compaction, can improve the bearing capacity of the foundation to some extent, but their effectiveness is limited and costs are high when dealing with areas with greater depth or particularly complex geological conditions. Furthermore, these methods may have a significant impact on the surrounding environment during construction, such as noise and vibration, which is detrimental to construction in urban areas.

[0003] To address the aforementioned issues, some foundation reinforcement pile products have emerged on the market. However, most of these products suffer from drawbacks such as simple structure, limited reinforcement effect, and complex construction. For example, some piles only increase bearing capacity by increasing pile diameter or length, neglecting the interaction between the pile and the surrounding soil; or the pile design is complex, making construction difficult and costly, thus hindering large-scale application. Utility Model Content

[0004] The purpose of this utility model is to provide a pile body for reinforcing settlement foundations to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a settlement foundation reinforcement pile, comprising an external fixed pile, wherein the outer wall of the external fixed pile is irregularly perforated with multiple permeation and reinforcement holes, the top of the external fixed pile is perforated with a grouting cavity, the inner wall of the grouting cavity is provided with an inner connecting column, the top of the inner connecting column is perforated with an inner through cavity, and the inner wall of the inner through cavity is provided with a reinforcing extension column.

[0006] As a further embodiment of this utility model: a plurality of connecting and fixing columns are uniformly and fixedly connected to the inner wall of the pouring cavity near the inner connecting column, and the ends of the plurality of connecting and fixing columns away from the outer fixing pile are fixedly connected to the outer wall of the inner connecting column.

[0007] As a further improvement of this utility model, the outer wall of the reinforcing extension column is uniformly and fixedly connected with multiple connecting limit blocks.

[0008] As a further improvement of this utility model: the inner wall of the inner through cavity, which matches the position of the multiple connecting limiting blocks, is uniformly provided with multiple through limiting grooves, and the multiple through limiting grooves are all opened through.

[0009] As a further embodiment of this utility model: the outer diameter of the plurality of connecting limiting blocks is matched with the inner diameter of the through limiting groove, and the plurality of connecting limiting blocks are slidably engaged with the through limiting groove.

[0010] Compared with existing technologies, the beneficial effects of this utility model are as follows: By irregularly opening multiple permeation reinforcement holes in the external fixed pile, the surrounding soil can form a tighter bond with the pile after it is implanted into the foundation, thereby improving the overall stability of the foundation. The design of the grouting cavity and the internal through-cavity allows for grouting after pile implantation, further enhancing the bond between the pile and the surrounding soil and improving the bearing capacity of the foundation. Simultaneously, the reinforced extension column increases the overall rigidity of the pile, effectively resisting foundation settlement.

[0011] The pile structure of this invention is rationally designed, with stable connections between components that are easy to install. During construction, no complex machinery is required, reducing construction difficulty and cost. Due to the irregular distribution of the permeation reinforcement holes on the external fixed pile, the pile can adapt to the foundation reinforcement needs under different geological conditions. Whether it is soft soil foundation or foundation prone to settlement, the pile of this invention can provide effective reinforcement.

[0012] Compared to traditional foundation reinforcement methods, the piles of this invention generate less noise and vibration pollution during construction, meeting environmental protection requirements. Furthermore, due to their simple construction and high efficiency, they also save energy and resources. Attached Figure Description

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Specific Implementation Example 1:

[0023] The settlement foundation reinforcement pile of this utility model was used in the foundation reinforcement project of a high-rise building.

[0024] First, the location and depth of the piles are determined based on the geological survey report. Then, a pile driver is used to drive the external fixed pile 1 into the foundation, ensuring that the permeation reinforcement hole 2 is in full contact with the surrounding soil. Next, the inner connecting column 4 is inserted into the grouting cavity 3 and fixedly connected to the external fixed pile 1 via the connecting fixing column 31. Afterward, the reinforcing extension column 5 is inserted into the inner through cavity 41, ensuring that the connecting limiting block 51 slides and engages with the through limiting groove 42. Finally, grouting is performed through the grouting cavity 3 and the inner through cavity 41. After the grout solidifies, the foundation reinforcement project is completed.

[0025] Actual monitoring showed that the foundation settlement of the high-rise building was significantly reduced, and the overall stability was significantly improved. Specific Implementation Example 2:

[0027] The settlement foundation reinforcement pile of this utility model was also used in the foundation reinforcement of a certain bridge project.

[0028] Because bridge engineering requires high bearing capacity of the foundation, the number and density of piles were increased during construction. After the external fixed pile 1 was installed, in addition to conventional grouting, geogrids and other reinforcing materials were laid around the piles to further improve the overall stability of the foundation. Actual testing showed that the foundation bearing capacity of the bridge project met the design requirements, and no significant settlement occurred during use.

[0029] Please see Figures 1-4 In this embodiment of the present invention, a settlement foundation reinforcement pile includes an outer fixed pile 1. Multiple permeation reinforcement holes 2 are irregularly perforated through the outer wall of the outer fixed pile 1. A pouring inner cavity 3 is perforated through the top of the outer fixed pile 1. An inner connecting column 4 is provided on the inner wall of the pouring inner cavity 3. An inner penetrating cavity 41 is perforated through the top of the inner connecting column 4. A reinforcing extension column 5 is provided on the inner wall of the inner penetrating cavity 41. Multiple connecting fixing columns 31 are uniformly fixedly connected to the inner wall of the pouring inner cavity 3 near the inner connecting column 4. The ends of the multiple connecting fixing columns 31 away from the outer fixed pile 1 are all fixedly connected to the outer wall of the inner connecting column 4.

[0030] Multiple connecting limit blocks 51 are uniformly fixedly connected to the outer wall of the reinforcing extension column 5. Multiple through-limit grooves 42 are uniformly formed on the inner wall of the inner through cavity 41, matching the positions of the multiple connecting limit blocks 51. All through-limit grooves 42 are through-holes. The outer diameter of each connecting limit block 51 matches the inner diameter of the corresponding through-limit groove 42, and the multiple connecting limit blocks 51 are slidably engaged with the corresponding through-limit grooves 42.

[0031] The working principle of this invention is as follows: Multiple permeation reinforcement holes 2 are irregularly opened through the outer wall of the external fixed pile 1, allowing moisture and fine particles in the surrounding soil to enter the interior of the pile or the gap between the pile and the soil through the holes. During the grouting process, the grout can fully penetrate into these gaps, forming a tight bond with the soil, thereby improving the overall strength and stability of the foundation.

[0032] The design of the inner cavity 3 and the inner through cavity 41 allows for grouting after the pile is implanted. During the solidification process, the grout forms a bond with the pile and the surrounding soil, tightly connecting the pile to the soil. This bond not only increases the bearing capacity of the pile but also enhances the overall stability of the foundation.

[0033] The reinforcement of the extension column 5 increases the overall rigidity of the pile. Under external forces, the reinforcement extension column 5 can effectively resist deformation and settlement, maintaining the stability of the pile. At the same time, the sliding engagement design between the connecting limiting block 51 and the through limiting groove 42 ensures a stable connection between the reinforcement extension column 5 and the inner connecting column 4, further improving the overall performance of the pile.

[0034] The pile structure design of this utility model takes into account the interaction between the pile and the surrounding soil. After the pile is implanted, grouting is used to form a tight bond between the pile and the soil, achieving a synergistic effect between the pile and the soil. This synergistic effect not only improves the bearing capacity of the foundation but also enhances its resistance to settlement.
