[0002] In today's society, with the development of the social economy, large high-rise buildings and underground space structures are rapidly developing, and foundation pit engineering is gradually advancing towards deeper and larger requirements. Foundation pit engineering has developed rapidly and is widely used, providing great convenience for the construction and use of buildings. Foundation pit support is the support, reinforcement, and protection measures adopted for the sidewalls of the foundation pit and surrounding facilities to ensure the safety of foundation excavation, foundation construction, and the surrounding buildings and structures. It should be given full attention by construction personnel. In traditional foundation pit support systems, the struts are prone to swaying during hoisting due to the lack of an effective positioning and guiding mechanism, making it difficult to accurately install them into the intended positions. This not only increases construction difficulty and prolongs the construction period, but also affects the stability of the entire foundation pit support structure due to inaccurate strut installation, posing a potential threat to construction safety. Therefore, developing a foundation pit support system that can effectively solve the above problems is of significant practical importance. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0016] Example 1: This utility model provides the following... Figures 1-3 The illustrated foundation pit support device includes symmetrically arranged sheet piles 1, steel columns 2, and struts 3 positioned between the sheet piles 1. Multiple insertion holes 21 are equidistantly provided on the steel columns 2. Multiple mounting blocks 22 are equidistantly arranged on one side of the steel columns 2. A positioning component 23 is movably mounted above the mounting blocks 22, and the positioning component 23 is used for positioning the steel columns 2 during installation. The design of the positioning component 23 ensures accurate installation of the struts 3, guaranteeing the reliability of the connection between the struts 3 and the steel columns 2, thereby enhancing the structural stability of the entire foundation pit support device and providing a more reliable safety guarantee for foundation pit construction.

[0017] Furthermore, the steel sheet pile 1 is driven into the soil according to the specifications using a vibratory impact pile driver. An impact mechanism is set between the body and the clamp of the vibratory pile driver. The vibration generated by the vibrator acts on the pile through the impact block. While the vibrator is vibrating up and down, it generates an impact force, which rapidly impacts the pile body while it is vibrating, greatly enhancing the penetration effect of the pile body.

[0018] Furthermore, multiple support plates 11 are equidistantly arranged on one side of the sheet pile 1. The support plates 11 are electrically welded to the sheet pile 1, and the support plates 11 are used to assist in the welding of the steel column 2 to the sheet pile 1. The support plates 11 arranged on one side of the sheet pile 1 can provide auxiliary support for the welding of the steel column 2 to the sheet pile 1, making the welding operation more convenient and stable, helping to improve the welding quality, and further enhancing the overall performance of the foundation pit support device.

[0019] Furthermore, a T-shaped groove 221 is provided on the mounting block 22.

[0020] Furthermore, the positioning component 23 includes a positioning block 231, a plug-in block 232, and a guide block 233. The positioning block 231 is U-shaped, the plug-in block 232 is fixedly connected to the back of the positioning block 231, and the guide block 233 is fixedly connected to the inner side of the positioning block 231. By setting the positioning component 23 on the steel column 2, the plug-in block 232 of the positioning component 23 is inserted into the insertion hole 21 of the steel column 2, and the guide block 233 is slidably connected to the sliders 31 on both sides of the support rod 3. This provides precise positioning and guidance for the support rod 3, effectively avoiding the problem of easy shaking and inaccurate positioning of the support rod 3 during hoisting in traditional devices, and greatly improving the installation accuracy of the support rod 3.

[0021] Furthermore, the plug block 232 is inserted into the socket 21 at the location where the support rod 3 is to be installed.

[0022] Furthermore, the two sides of the support rod 3 are fixedly connected to the slider 31, and the slider 31 is slidably connected in the T-shaped groove 221.

[0023] Example 2: This utility model provides the following... Figures 1-3 The building foundation pit support device shown includes symmetrically arranged steel sheet piles 1, steel columns 2, and support rods 3 arranged between the steel sheet piles 1. Multiple insertion holes 21 are equally spaced on the steel columns 2. Multiple mounting blocks 22 are equally spaced on one side of the steel columns 2. A positioning component 23 is movably arranged above the mounting block 22. The positioning component 23 is used for the installation and positioning of the steel columns 2.

[0024] Furthermore, the slider 31 is slidably connected to the guide block 233, which is used to assist the slider 31 in sliding into the T-shaped groove 221.

[0025] Working principle: First, a vibratory impact pile driver is used to drive the steel sheet piles 1 into the soil according to specifications. Then, when installing the steel column 2, support plates 11, equidistantly arranged on one side of the steel sheet pile 1, provide support for the steel column 2, making the welding operation between the steel column 2 and the steel sheet pile 1 more stable. With the assistance of the support plates 11, construction personnel can more easily carry out the welding work between the steel column 2 and the steel sheet pile 1, ensuring welding quality and thus guaranteeing the structural stability and reliability of the entire foundation pit support device.

[0026] When installing the support rod 3, insert the plug 232 of the positioning component 23 into the plug hole 21 on the steel column 2 corresponding to the position where the support rod 3 is to be installed, and snap the positioning component 23 onto the steel column 2 to provide a positioning reference for the subsequent installation of the support rod 3.

[0027] During the hoisting of the support rod 3, the sliders 31 fixedly connected to both sides of the support rod 3 are aligned with the T-shaped grooves 221 of the mounting blocks 22 on the steel column 2. The guide blocks 233 of the positioning assembly 23 act as guides, guiding the sliders 31 to slide smoothly into the T-shaped grooves 221. As the sliders 31 slide within the T-shaped grooves 221, the support rod 3 gradually approaches and accurately reaches the predetermined installation position, achieving rapid and accurate installation of the support rod 3. Finally, high-strength bolts are used to thread-tighten and fix the sliders 31 to the steel column 2.
