Description

Technical Field

[0001] This invention relates to the field of anchorage structures, and more particularly to an anchorage structure for a permanent and temporary combined fastening system. Background Technology

[0002] In the construction of long-span bridges, anchorage structures are a common type of anchorage, primarily used for anchoring points in structures such as the backstays of arch bridges, the stay cables of cable-stayed bridges, and the main cables of suspension bridges. However, traditional anchorage structures have several drawbacks, including material waste, unstable anchoring force, high maintenance costs, and poor safety. These issues limit the development and application of anchorage structures.

[0003] Traditional anchorage structures typically involve excavating deep foundation pits, pouring concrete gravity anchors, and connecting the concrete anchorages with anchor plates. However, this method requires a large amount of steel and concrete, resulting in material waste and high maintenance costs. Furthermore, the anchoring force of traditional anchorage structures is often difficult to guarantee, potentially jeopardizing the overall structural safety. Additionally, deep foundation pit structures require extensive earthwork and long construction periods, while reinforced concrete anchorages demand substantial amounts of steel and concrete, leading to further material waste and high maintenance costs.

[0004] In existing technologies, commonly used anchor structures typically employ reinforced concrete or prestressed concrete, and their structure mainly consists of anchorage seats at the anchoring end, steel strands, and prestressed steel bars. These existing technological solutions have the following drawbacks:

[0005] Material waste: Traditional anchor structures require a large amount of materials such as concrete and steel to support and fix the structure, resulting in material waste.

[0006] Unstable anchoring force: Some existing anchoring solutions are prone to displacement or tilting when encountering natural disasters such as strong winds or earthquakes, thus affecting the stability of the structure.

[0007] Poor safety: Some existing anchor structures are prone to structural damage or collapse when encountering extreme weather or natural disasters, posing significant safety hazards. Summary of the Invention

[0008] The purpose of this invention is to provide a permanent-temporary combined anchoring system structure to solve the technical problems of material waste, unstable anchoring force, and poor safety in existing anchor structures. It utilizes techniques such as anchoring with the pile foundation of the bridge approach bridge, supplementing with anti-slide piles to enhance the anchoring force, connecting the anti-slide piles and the approach bridge pile foundation with a concrete structure operating chamber, and using sandbags to load the top surface of the structure. This ensures the stability and safety of the entire structure while also saving materials and costs.

[0009] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0010] A permanent and temporary combined anchoring system includes a bridge approach bridge pile foundation, anti-slide piles, and a reinforced concrete connection structure. The reinforced concrete connection structure is located between the bridge approach bridge pile foundation and the anti-slide piles, and its two sides are connected to the bridge approach bridge pile foundation and the anti-slide piles, respectively. Embedded pipes are pre-embedded in the anti-slide piles and the reinforced concrete connection structure. The pre-embedded pipes are inclined, and an operating space is provided at the bottom of the reinforced concrete connection structure. The pre-embedded pipes are connected to the operating space.

[0011] Furthermore, the adjacent surfaces between the reinforced concrete connection structure and the operating space are set as inclined surfaces, with the angle between the inclined surfaces and the pre-embedded pipes between 60-90°. The operating space is used for operators to perform their work.

[0012] Furthermore, a load-bearing pre-embedded steel reinforcement frame is pre-embedded inside the inclined surface, and a pre-embedded plate is pre-embedded on the outside of the load-bearing pre-embedded steel reinforcement frame. The pre-embedded pipe passes through the pre-embedded plate, which is a steel plate structure.

[0013] Furthermore, the steel strand is inserted into the pre-embedded pipe, and an anchor seat is welded onto the pre-embedded plate. The anchor seat is fixedly connected to the steel strand, and the angle between the anchor seat and the steel strand is 90°.

[0014] Furthermore, several sandbags are placed at the top of the bridge approach pile foundation, anti-slide piles, and reinforced concrete connection structure. The sandbag load increases the safety of the structure and reduces the amount of concrete used.

[0015] Furthermore, the anchoring is achieved by using the bridge approach bridge pile foundation cap. Anchors are fixed to the cap by setting embedded parts in front of the bridge approach bridge pile foundation cap. The embedded parts are made of high-strength steel to ensure the firmness and durability of the anchoring. The embedded parts are fixedly connected by a reinforced concrete connection structure.

[0016] Furthermore, the anti-slide piles enhance the anchoring force, utilize underground rock mass for anchoring, reduce the volume of gravity anchoring, and are made of reinforced concrete.

[0017] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0018] This invention utilizes a combination of techniques, including anchoring the bridge approach bridge's pile foundation, reinforcing the anchoring force with anti-slide piles, connecting the anti-slide piles and the approach bridge's pile foundation with a concrete structure operating chamber, and using sandbags to load the top surface of the structure. These techniques ensure the stability and safety of the entire structure while reducing material and maintenance costs. The concrete structure operating chamber connects the anti-slide piles and the approach bridge's pile foundation. Steel pipes are pre-embedded within the connecting structure according to the backstay positions. The chamber provides operating space, and pre-embedded plates, anchorages, and steel strands are installed. Simultaneously, the steel strands are tensioned within the chamber. Furthermore, the use of sandbags to load the top surface of the structure increases structural safety and saves costs. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the present invention, and these aspects of the invention can be implemented even without these specific details.

[0022] like Figure 1 As shown, a permanent-temporary combined anchoring system includes a bridge approach bridge pile foundation 1, anti-slide piles 4, and a reinforced concrete connecting structure 5. The reinforced concrete connecting structure 5 is located between the bridge approach bridge pile foundation 1 and the anti-slide piles 4, and its two sides are connected to the bridge approach bridge pile foundation 1 and the anti-slide piles 4, respectively. Embedded pipes 3 are pre-embedded in the anti-slide piles 4 and the reinforced concrete connecting structure 5, and the pre-embedded pipes 3 are inclined. An operating space 7 is provided at the bottom of the reinforced concrete connecting structure 5, and the pre-embedded pipes 3 are connected to the operating space 7. This system utilizes techniques such as anchoring the bridge approach bridge pile foundation, supplementing with anti-slide piles to enhance anchoring force, connecting the anti-slide piles and the approach bridge pile foundation with a concrete operating chamber, and using sandbags to load the top surface of the structure. These methods ensure the stability and safety of the entire structure while also saving materials and costs.

[0023] In this embodiment of the invention, the adjacent surfaces between the reinforced concrete connection structure 5 and the operating space 7 are set as inclined surfaces, with the angle between the inclined surface and the embedded pipe 3 between 60-90°. The operating space 7 is used for operators to perform their work. This reduces material and maintenance costs while ensuring stability and safety. An angle between 60-90° improves the handling performance.

[0024] In this embodiment of the invention, a pre-embedded reinforcing steel frame 6 is embedded inside the inclined surface, and a pre-embedded plate 9 is embedded outside the pre-embedded reinforcing steel frame 6. The pre-embedded pipe 3 passes through the pre-embedded plate 9, and the pre-embedded plate 9 is a steel plate structure.

[0025] In this embodiment of the invention, a pre-embedded pipe 3 is inserted into a steel strand, and an anchor seat 8 is welded onto a pre-embedded plate 9. The anchor seat 8 is fixedly connected to the steel strand, and the angle between the anchor seat 8 and the steel strand is 90°. The anchor structure of this invention adopts a permanent and temporary combined fastening system. One side of the structure is anchored using the pile foundation of the bridge approach bridge, and the other side is reinforced with anti-slide piles to enhance the anchoring force, thereby meeting the stress requirements. A concrete structure operating chamber is used in the middle to connect the anti-slide piles and the approach bridge foundation. Steel pipes are pre-embedded in the connecting structure according to the backstay position. The chamber has operating space, where the pre-embedded plate, anchor seat at the anchoring end, and steel strand are installed. At the same time, the steel strand is tensioned in the chamber. In addition, sandbags are used to load the top surface of the structure of this invention to increase structural safety and save costs.

[0026] In this embodiment of the invention, several sandbags 2 are installed at the top of the bridge approach bridge pile cap 1, anti-slide piles 4, and reinforced concrete connection structure 5. The sandbags 2 increase the structural safety and reduce the amount of concrete used. Using sandbags to load the top surface of the structure increases structural safety, reduces concrete usage, and saves costs.

[0027] In this embodiment of the invention, the bridge approach bridge pile foundation 1 is used for anchoring. An anchor is fixed on the pile foundation by setting an embedded part at the front of the bridge approach bridge pile foundation 1. The embedded part is made of high-strength steel to ensure the firmness and durability of the anchoring. The embedded part is fixedly connected by a reinforced concrete connection structure 5.

[0028] In this embodiment of the invention, the anti-slide pile 4 enhances the anchoring force, utilizes underground rock mass for anchoring, reduces the volume of gravity anchoring, and is made of reinforced concrete.

[0029] For pile foundation anchoring, one side of the structure of this invention utilizes the pile foundation anchoring of a bridge approach bridge. An anchor is fixed to the pile foundation by setting an embedded part at the front of the anchor. The embedded part can be made of high-strength steel to ensure the firmness and durability of the anchoring.

[0030] Anti-slide piles enhance anchorage force, and anti-slide piles are also used for anchorage on the other side of the structure. These anti-slide piles utilize underground rock mass for anchorage, reducing the volume of gravity anchorage. Reinforced concrete is used for the anti-slide piles, and the rock penetration depth and structural dimensions are determined based on geological surveys, with construction carried out according to requirements.

[0031] The anchorage connection structure and the tunnel are connected by a concrete operating tunnel to link the pile caps and anti-slide piles of the bridge approach spans. Steel pipes are pre-embedded in the operating tunnel according to the backstay positions. An operating space is provided within the tunnel, where embedded plates, anchorage end anchors, and the steel strands of the tensioning system are installed. The tunnel serves as the tensioning operation position, and the steel strands of the tensioning system enter the tunnel through the embedded pipes for tensioning and anchoring.

[0032] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
