Description

Technical Field

[0001] This invention belongs to the field of foundation pit reinforcement and protection, and more specifically, it provides a protective structure and method for foundation pit reinforcement in geotechnical engineering. Background Technology

[0002] Geotechnical engineering foundation pit support and reinforcement refers to the reinforcement and protection measures taken to ensure the safety of the underground structure construction underway or to be constructed and the surrounding environment by using appropriate and reliable support for the foundation pit sidewalls and the surrounding environment.

[0003] The choice of support structure for foundation pits should be determined through a comprehensive economic, technical, and environmental analysis and comparison, taking into account factors such as the surrounding environment, underground structure conditions, excavation depth, engineering geological and hydrogeological conditions, construction conditions, construction season, and local engineering experience. Geotechnical engineering places high demands on foundation pit conditions, requiring the use of testing methods to investigate and study the construction site, analyze and assess the geological conditions and natural environment of the construction site, and ensure measures are taken to guarantee the strength and stability of the foundation and prevent unacceptable deformation.

[0004] When continuous construction is required during foundation pit protection, proper drainage is essential to prevent collapse. Furthermore, dewatering must be considered during excavation and construction. Based on a search of existing patents and current equipment, it has been found that support rods have several drawbacks and limitations, such as the connection between the hinges and the ground; and the tendency for top landslides or water accumulation to occur with support plates. Geotechnical engineering, involving personal safety, places high demands on foundation pit conditions, requiring analysis and assessment of the geological conditions and natural environment of the construction site. Therefore, foundation pit support has become a crucial and urgent problem to be solved in the current foundation pit excavation process.

[0005] Currently, there is a lot of patent research on solutions for specific engineering geological conditions, surrounding environment and foundation pit type or high slope deep foundation pit support, but there are few practical methods for selecting a safe, reliable, economical and reasonable horizontal, vertical and lateral support and protection solution for special geological environments or complex natural environments. Summary of the Invention

[0006] Therefore, in view of this, in order to solve the support problems existing in the above-mentioned engineering foundation pits, the present invention provides a protective structure and method for reinforcing foundation pits in geotechnical engineering. The mechanism and method provided by this solution are simple to operate, economical and safe, have minimal impact on the surrounding environment of the foundation pit, and can reliably reinforce and protect the foundation pit of geotechnical engineering, playing an important role in reducing the displacement of the retaining structure, protecting surrounding buildings and underground pipelines, and minimizing displacement.

Specifically, the vertical support system consists of two uprights (left and right), a central upright, and multiple horizontal bars. This vertical support system includes a sleeve mounted on the central upright that can slide along the upright's axis, evenly distributed pin holes, and hydraulic devices. Each hydraulic device has two fixed horizontal bars, and these horizontal bars are linearly symmetrical with respect to the axis of the hydraulic device, and their lengths are adjustable. The horizontal support system consists of two horizontal bars (left and right), two horizontal crossbars, a central support system, and four diagonal bars. This horizontal support system includes a sleeve mounted on the central upright that can slide along the upright's axis, evenly distributed pin holes, and hydraulic devices. Each hydraulic device has two fixed horizontal bars, and the horizontal bars on each hydraulic device are linearly symmetrical with respect to the axis of the hydraulic device, and their lengths are adjustable. The central support system includes a hydraulic device with four horizontal bars fixed on it. Each horizontal bar is linearly symmetrical with respect to the axis of the hydraulic device.

[0011] Furthermore, pin holes are evenly distributed on the two horizontal crossbars.

[0012] Furthermore, the hydraulic devices on the central support system and the hydraulic devices in the vertical support system are not the same equipment. The hydraulic devices on the central support system are mainly used to support the left and right horizontal bars in the horizontal support system, while the hydraulic devices in the vertical support system are mainly used to support the left and right vertical bars in the vertical support system.

[0013] Furthermore, each of the four diagonal braces has a pin at its top, away from the central support system. The pin at the top of the diagonal brace can be inserted into the two horizontal crossbars to adjust the protective width of the lateral support system.

Based on the analysis and judgment of the geological conditions and natural environment of the construction site, a scheme is developed to adjust each system to ensure the strength and stability of the foundation and to prevent unacceptable deformation, thereby improving the stability of the support system.

[0027] Sleeves that can slide along the axis of the poles are installed on the central vertical pole of the vertical support system and the horizontal crossbar of the horizontal support system.

The size and dimensions of the support system can be set according to the specific environment of the construction site. The operation is simple, safe and reliable.

[0028] A grid mesh was installed in the lateral support system to effectively prevent the pit sidewalls from sliding into the pit, making the support effect of the protective support system more prominent and reducing the weight of the entire support system, which is beneficial for on-site construction and handling.

[0029] Drainage holes are installed in the lateral support system to facilitate the drainage of accumulated water in the foundation pit, prevent the collapse of the foundation pit sidewalls, and the flow rate of the drainage holes is adjustable to prevent external water from flowing into the foundation pit or the drainage outlet from being blocked.
