Description

Technical Field

[0001] This application relates to the field of foundation reinforcement technology, specifically a highly protective rooted pile pier structure. Background Technology

[0002] In civil engineering, especially in bridge construction, foundation reinforcement technology has always been one of the key technologies to ensure the safety and stability of buildings. Traditional foundation reinforcement methods mainly include driven piles and cast-in-place piles. These methods can improve the bearing capacity of the foundation to a certain extent, but they still have certain limitations when facing complex geological conditions. In recent years, with the development of new building materials and technologies, some innovative foundation reinforcement technologies have been gradually applied to actual projects, such as composite piles and prestressed anchor cables. These new technologies not only improve the bearing capacity of the foundation, but also show significant advantages in terms of construction efficiency and environmental protection.

[0003] Driven piles: Precast piles are driven into the soil using mechanical force. Suitable for hard soils but not for soft soil environments. Advantages include fast construction speed and relatively low cost; disadvantages include significant disturbance to the surrounding soil, potentially causing ground settlement. Cast-in-place piles: Piles are formed by drilling and then pouring concrete. They are highly adaptable and can be used in various geological conditions. Advantages include effective settlement control and reduced impact on the surrounding environment; disadvantages include long construction periods and higher costs. Composite piles: Combining the advantages of driven piles and cast-in-place piles, the strength of the pile is increased by injecting cement grout or other reinforcing materials inside the precast pile. This method can improve the performance of a single pile type to some extent, but it still cannot completely overcome the problem of poor pile foundation stability under complex geological conditions.

[0004] While traditional pile foundation technology can meet engineering requirements to a certain extent, its compressive strength and long-term stability are still insufficient in harsh environments such as soft soil foundations. Especially for deep foundation engineering, simply increasing the pile length or diameter is not enough to fundamentally solve the problem and can easily lead to pile foundation damage or even safety hazards to the entire building. In order to solve the above problems, a highly protective rooted pile pier structure is proposed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a highly protective rooted pile pier structure, which significantly improves the bearing capacity and stability of pile foundations under soft soil conditions and reduces the risk of building settlement.

[0006] To achieve the above objectives, this application provides the following technical solution: a highly protective root-planted pile pier structure, comprising a pier, with a root-planted pile fixedly connected to the bottom end of the pier, a reinforcing mechanism provided between the pier and the root-planted pile, the reinforcing mechanism comprising multiple connecting ribs, each of the connecting ribs having multiple intertwined reinforcing ribs installed on its exterior, the upper and lower ends of each connecting rib and reinforcing rib being fixedly connected to the sides of the pier and the root-planted pile respectively, a protective mechanism provided on the exterior of the root-planted pile, the protective mechanism comprising a protective sleeve fixedly connected to the outer surface of the root-planted pile, the top end of the protective sleeve being fixedly connected to the outer surface of the pier, and a lead core connecting seat embedded at the connection between the pier and the root-planted pile.

[0007] The above-mentioned scheme, through the reinforcement mechanism, can evenly transfer the force on the pier to the root pile. Since the bottom of the root pile extends deep into the ground, its strong grip can effectively resist horizontal displacement and vertical settlement. At the same time, the lead core connector embedded between the pier and the root pile can effectively improve the vibration resistance of the structure, thereby improving the stability of the structure. Furthermore, the protective mechanism set between the pier and the root pile effectively prevents harmful substances from entering the root pile, protecting the root pile from damage, extending the service life of the structure, reducing maintenance costs, and making it more practical.

[0008] Furthermore, the reinforcing ribs are made of high-quality carbon steel wire.

[0009] The above solution, by limiting the material of the reinforcing ribs, can increase the overall structural stiffness and shear resistance.

[0010] Furthermore, the casing is made of highly corrosion-resistant stainless steel.

[0011] The above solution optimizes the protective effect of the casing by limiting its material, preventing harmful substances from entering the root pile and protecting it from damage.

[0012] Furthermore, a buffer material, namely polyurethane foam, is filled between the casing and the root pile.

[0013] The above-mentioned solution utilizes cushioning materials to effectively absorb external impact energy, thereby improving the protective effect of the protective mechanism.

[0014] Furthermore, the lead core connector includes two connecting steel plates and an outer rubber protective layer. The two connecting steel plates are respectively embedded inside the pier and the root pile. The upper and lower ends of the outer rubber protective layer are respectively fixedly connected to the two connecting steel plates on their sides that are close to each other.

[0015] The above solution provides protection for the internal components by setting an outer rubber protective layer, preventing them from being corroded by the external environment and improving the service life and durability of the lead core connector.

[0016] Furthermore, a lead core column is fixedly connected to the inner wall of the outer rubber protective layer, and a filler layer is filled between the lead core column and the outer rubber protective layer.

[0017] The above scheme allows the lead core column to absorb and dissipate vibration energy through plastic deformation under vibration, thereby reducing the vibration response of the structure.

[0018] Furthermore, the interior of the filling layer consists of multiple layers of steel plates and a rubber layer filled between the steel plates.

[0019] The above scheme provides flexible deformation capability by limiting the composition of the filling layer, allowing the lead core connector to undergo large displacement in the horizontal direction, and also increases the overall stiffness and load-bearing capacity of the lead core connector.

[0020] Furthermore, the outer surface of the bottom of the rooted pile is coated with an impermeable layer.

[0021] The above solution effectively prevents groundwater from seeping into the root piles by setting an impermeable layer, thus extending their service life.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This highly protective root-planted pile pier structure, through its reinforced mechanism, can evenly transfer the force on the pier to the root-planted pile, dispersing external loads, reducing stress concentration, and improving the overall stability of the structure. Because the bottom of the root-planted pile extends deep into the ground, its strong grip can effectively resist horizontal displacement and vertical settlement. Simultaneously, the lead-core connecting seat embedded between the pier and the root-planted pile effectively enhances the structure's vibration resistance, thereby improving its stability. Furthermore, the protective mechanism between the pier and the root-planted pile effectively prevents harmful substances from entering the root-planted pile, protecting it from damage, extending the structure's service life, reducing maintenance costs, and making it more practical.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a high-protection root-planted pile pier structure includes a pier 1, with a root-planted pile 2 fixedly connected to the bottom end of the pier 1. A reinforcing mechanism 3 is provided between the pier 1 and the root-planted pile 2. The reinforcing mechanism 3 includes multiple connecting ribs 301, and multiple intertwined reinforcing ribs 302 are installed on the outside of each connecting rib 301. The reinforcing ribs 302 are made of high-quality carbon steel wire. By limiting the material of the reinforcing ribs 302, the rigidity and shear resistance of the overall structure can be increased. The upper and lower ends of each connecting rib 301 and reinforcing rib 302 are respectively connected to the pier 1 and the root-planted pile 2. The two sides are fixedly connected, and the connecting ribs 301 and reinforcing ribs 302 work together to improve the shear resistance of the pier 1, prevent the structure from cracking and deforming under extreme loads, and disperse external loads, reduce stress concentration, and improve the overall stability of the structure. The outer surface of the bottom of the root pile 2 is coated with an anti-seepage layer 6. The anti-seepage layer 6 can effectively prevent groundwater from seeping into the root pile 2 and extend its service life. It should be noted that the bottom of the root pile 2 penetrates into the ground through the anti-seepage layer 6 and is in close contact with the foundation.

[0032] Please see Figure 1 , Figure 3 and Figure 4The root pile 2 is provided with a protective mechanism 4. The protective mechanism 4 includes a protective sleeve 401 fixedly connected to the outer surface of the root pile 2. The top of the protective sleeve 401 is fixedly connected to the outer surface of the pier 1. The protective sleeve 401 can isolate external corrosive substances. The protective sleeve 401 is made of highly corrosion-resistant stainless steel. By limiting the material of the protective sleeve 401, the protective effect of the protective sleeve 401 can be optimized, preventing harmful substances from entering the root pile 2 and protecting the root pile 2 from damage. The space between the protective sleeve 401 and the root pile 2 is filled with a buffer material 402. The buffer material 402 is polyurethane foam. The buffer material 402 can effectively absorb external impact energy, improve the protective effect of the protective mechanism 4, effectively extend the service life of the structure, and reduce maintenance costs.

[0033] Please see Figure 3 and Figure 4 A lead core connector 5 is embedded at the connection between the pier 1 and the root pile 2. The lead core connector 5 includes two connecting steel plates 501 and an outer rubber protective layer 502. The two connecting steel plates 501 are respectively embedded inside the pier 1 and the root pile 2. The upper and lower ends of the outer rubber protective layer 502 are respectively fixedly connected to the sides of the two connecting steel plates 501 that are close to each other. The outer rubber protective layer 502 can protect the internal components, prevent them from being corroded by the external environment, and improve the service life and durability of the lead core connector 5. A lead core column 503 is fixedly connected to the inner wall of layer 502. A filling layer 504 is filled between the lead core column 503 and the outer rubber protective layer 502. The lead core column 503 can absorb and dissipate vibration energy through plastic deformation under vibration, thereby reducing the vibration response of the structure. The interior of the filling layer 504 is composed of multiple layers of steel plates and rubber layers filled between the steel plates. By limiting the composition of the filling layer 504, flexible deformation capability can be provided, allowing the lead core connector 5 to undergo large displacement in the horizontal direction, and also increasing the overall stiffness and load-bearing capacity of the lead core connector 5.

[0034] In this embodiment, a highly protective root-planted pile pier structure, through the reinforcement mechanism 3, can evenly transmit the force on the pier 1 to the root-planted pile 2. Since the bottom of the root-planted pile 2 extends deep into the ground, its strong grip can effectively resist horizontal displacement and vertical settlement. At the same time, the lead core connecting seat 5 embedded between the pier 1 and the root-planted pile 2 can effectively improve the vibration resistance of the structure, thereby improving the stability of the structure. Furthermore, the protective mechanism 4 set between the pier 1 and the root-planted pile 2 effectively prevents harmful substances from entering the interior of the root-planted pile 2, protecting the root-planted pile 2 from damage, extending the service life of the structure, reducing maintenance costs, and making it more practical.

[0035] The working principle of the above embodiment is as follows: When the building above the pier 1 is subjected to a load, the force is first transmitted to the pier 1, and then evenly distributed to the root piles 2 through the connecting ribs 301 and reinforcing ribs 302. Since the bottom of the root piles 2 extends deep into the ground, their strong grip can effectively resist horizontal displacement and vertical settlement. Furthermore, the anti-seepage layer 6 can effectively prevent the seepage of groundwater. At the same time, the lead core connecting seat 5 can buffer the transmitted force and the generated vibration. Specifically, the lead core column 503 has a low yield strength and good plastic deformation capacity. When the force is transmitted through the lead core connecting seat 5, the lead core column 503 undergoes plastic deformation during shear deformation, thereby absorbing and dissipating the energy of the force. The rubber layer in the filling layer 504 allows for large horizontal deformation while having low stiffness, which can extend the force transmission cycle. This flexible deformation plays a role in buffering the transmitted force to a certain extent. With the cooperation of the internal components of the lead core connector 5, it can provide a certain rigidity support structure and absorb and dissipate external forces, achieving good buffering and vibration isolation effects and improving the stability of the structure. The casing 401 can prevent harmful substances from entering the root pile 2 and protect the root pile 2 from damage. The buffer material 402 filled between the casing 401 and the root pile 2 can effectively absorb external impact energy, thereby optimizing the protective effect of the casing 401 and making the structure have high reliability and service life.
