[0015] Retaining piles, also known as support piles, are a series of pile structures installed around an excavation pit to retain soil and water during excavation. Their main function is to prevent soil and groundwater intrusion during excavation, ensuring the stability of the pit and construction safety. As a crucial component of the pit support system, retaining piles play a vital role in ensuring the smooth progress of underground engineering projects.

[0016] Retaining piles are widely used in various underground engineering projects, especially in situations requiring deep foundation pits. Here are some typical application scenarios: High-rise building foundation construction: Deep foundation pits are often required for the construction of basements in high-rise buildings. Retaining piles effectively prevent slope instability and groundwater leakage, ensuring construction safety. Subway engineering: The construction of subway stations and tunnels often involves deep foundation pit excavation. Retaining piles support the foundation pit slopes, prevent soil collapse, and block groundwater intrusion, ensuring the smooth progress of subway projects. Underground utility tunnel construction: As an important component of urban infrastructure, underground utility tunnels also require foundation pit excavation during construction. Retaining piles ensure the stability of the foundation pit and prevent soil and groundwater from interfering with the construction of the utility tunnel. Bridge foundation construction: In bridge foundation construction, especially when bridges need to cross rivers, lakes, or other bodies of water, the excavation depth is often significant. Retaining piles prevent slope instability and ensure the stability of the bridge foundation.

[0017] There are many types of retaining piles. Based on differences in materials, construction methods, and functions, they can be divided into the following categories: Steel sheet piles are steel sections with interlocking joints. Their cross-sectional shapes include U-shaped (also known as "Larsen sheet piles"), Z-shaped, and channel-shaped. These steel sheet piles of different shapes can be interconnected through interlocking joints to form a continuous retaining structure. Steel sheet piles are easy to construct, have moderate rigidity, and are suitable for various soil conditions, but waterproofing measures are necessary. Cement mixing piles use cement as a curing agent. A cement mixing machine injects cement into the soil and mixes it thoroughly, causing a series of physicochemical reactions between the cement and the soil, hardening the soft soil and increasing the foundation strength. Cement mixing piles have good water-stopping performance and are suitable for soft soil strata. High-pressure jet grouting piles are constructed by drilling holes and using high-pressure rotating nozzles to inject cement slurry into the soil layer, mixing it with the soil to form a continuously overlapping cement-reinforced structure. High-pressure jet grouting pile construction requires less land, has less vibration, and lower noise, but the cost is higher, and it is not suitable for special soil types where the injected slurry cannot solidify. Drilled cast-in-place piles are constructed by creating pile holes in the foundation soil on-site using methods such as mechanical drilling, steel pipe extrusion, or manual excavation, then placing a reinforcing cage inside and pouring concrete. Drilled cast-in-place piles have high rigidity, are suitable for deep and large foundation pits, and have minimal impact on the surrounding strata and environment. PC (Precast Concrete) piles combine Larssen piles with steel pipes to create piles with various cross-sectional combinations. This type of pile increases cross-sectional stiffness, enhances its ability to retain soil and water, and provides better retaining capacity. SMW (Soil Movable Water) piles insert H-beams or other materials (usually H-beams, but sometimes Larssen sheet piles or steel pipes) into cement-soil piles, integrating load-bearing and seepage prevention / water-blocking functions. SMW piles have high strength, good water-stopping properties, and the inserted steel sections can be pulled out and reused, making them economical. Diaphragm walls are continuous reinforced concrete walls formed by excavating deep trenches along both sides of the axis of a deep excavation project using trenching machinery on the ground, placing a reinforcing cage inside the trench, and pouring underwater concrete. Diaphragm walls have high rigidity, large excavation depth, high strength, small displacement, and good water resistance, and can also serve as part of the main structure. However, they are more expensive.

[0018] Positioning frames, as a crucial positioning and support device, are widely used in various engineering and technical fields. Their basic definition is: a device used to fix, support, and position various equipment, workpieces, or structures. They are typically made of metal or other robust materials and have a specific shape and structure to meet specific positioning and support requirements. Positioning frames ensure the stability and accuracy of equipment, workpieces, or structures during processing, installation, or use by providing precise support and positioning.

[0019] Positioning frames come in many varieties and can be categorized as follows based on different classification standards: Metal positioning frames: Made of metal materials such as steel and aluminum alloys, they feature high strength, corrosion resistance, and high temperature resistance, suitable for heavy-duty and harsh environments. Non-metallic positioning frames: Made of non-metallic materials such as plastics and rubber, they are lightweight, corrosion-resistant, and easy to process, suitable for lightweight and precision applications. Three-dimensional positioning frames: With a three-dimensional spatial structure, they can provide positioning and support in both horizontal and vertical directions, suitable for positioning and support of complex structures. Planar positioning frames: Primarily provide positioning and support in a two-dimensional plane, suitable for processing and installing planar workpieces or structures. General-purpose positioning frames: Applicable to various equipment and workpieces, with wide versatility. Special-purpose positioning frames: Designed for specific equipment or workpieces, offering higher precision and adaptability. Machining positioning frames: Used for positioning and support in machining to ensure machining accuracy and workpiece stability. Construction positioning frames: Used for positioning and support in construction to ensure the stability and accuracy of buildings. Medical equipment positioning frames: Used for positioning and support in medical surgery to ensure the precision and safety of the procedure.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Reference Figs. 1-2 As shown, this embodiment provides an adjustable retaining pile positioning frame, including symmetrically arranged guide rods 1. One end of the top surface of the two guide rods 1 is fixedly installed with a positioning rod 2 by a positioning bolt 4. The end of the guide rod 1 away from the positioning rod 2 is fixedly connected to the ground by a positioning bolt 4. Multiple guide rods 1 are freely stacked and assembled according to the plane line of the retaining pile by the positioning bolt 4.

[0023] The positioning frame is composed of symmetrically arranged guide rods 1 and positioning rods 2, which can be freely stacked and assembled to adapt to the planar shape of the retaining piles and can form angles, making it suitable for different situations. This design improves the flexibility and applicability of the positioning frame, enabling it to adapt to retaining piles of different shapes and sizes, thereby improving construction efficiency and accuracy. This utility model adopts a retaining pile construction positioning frame that can be adjusted according to different retaining pile sizes and planar shapes, making it highly versatile. The materials used in this utility model are common; the guide rods 1 and positioning rods 2 can be made of square steel, steel pipes, angle steel, etc., based on available materials, making them simple to manufacture and quick to put into use. This utility model can be disassembled and moved, increasing the applicability of this device in different project constructions.

[0024] To further optimize the design, several positioning holes 3 are provided on both the positioning rod 2 and the guide rod 1, with these holes spaced equally apart. These positioning holes 3 provide a fixed position for the positioning bolts 4, making the connection between the positioning rod 2 and the guide rod 1 more stable and precise. Simultaneously, the equally spaced positioning holes 3 also facilitate adjustment of the height and position of the positioning frame, further improving its flexibility and applicability.

[0025] The design is further optimized by using positioning bolts 4 to secure the guide rod 1 and positioning rod 2 by passing them sequentially through the positioning holes 3 on both. This fixing method is not only simple and convenient but also ensures a firm and reliable connection between the positioning rod 2 and the guide rod 1. Furthermore, the presence of the positioning holes 3 allows for adjustment of the position of the positioning bolts 4 as needed, thereby enabling precise adjustment of the height and angle of the positioning frame.

[0026] The design was further optimized by stacking and assembling the guide rods 1 by sequentially passing the positioning bolts 4 through the positioning holes 3 on the guide rods 1. This stacking and assembly method allows the positioning frame to expand and contract freely as needed to accommodate retaining piles of different lengths. Simultaneously, the presence of the positioning holes 3 ensures that the stacked positioning frame remains stable and precise, thereby improving construction efficiency and accuracy.

[0027] A further optimized design incorporates a positioning pad 5 fixedly connected to the bottom of the positioning bolt 4, with the positioning pad 5 in contact with the ground. The positioning pad 5 increases the contact area between the positioning bolt 4 and the ground, thereby improving the stability and load-bearing capacity of the positioning bolt 4. Simultaneously, the positioning pad 5 prevents the positioning bolt 4 from being directly pressed into the ground, thus protecting the integrity of the ground. This design further enhances the stability and load-bearing capacity of the positioning frame, ensuring safety and accuracy during construction.
