The application challenges and solutions of support oil cylinders in complex geological conditions

With the continuous development and deepening of construction engineering, the utilization of underground space has become increasingly frequent, especially in complex geological conditions such as high ground stress, fractured rock layers, and rich aquifers. Excavation and support work of foundation pits have become particularly important. As a key component of the foundation pit support system, the stability and reliability of the support oil cylinder's performance are directly related to the safety and progress of the entire foundation pit project. This article will explore the application challenges of support oil cylinders in complex geological conditions and propose corresponding solutions.

1、 Application challenges

The geological conditions are variable

Under complex geological conditions, geological structures are diverse, such as soft soil, hard rock, karst, etc. Each geological structure has different requirements for the bearing capacity and stability of the support oil cylinder. Meanwhile, changes in geological conditions may also lead to issues such as displacement and settlement of the support oil cylinder during construction.

Difficulty in construction

Under complex geological conditions, excavation and support construction of foundation pits are difficult and require the use of various support technologies and equipment. As one of them, the installation, debugging, and use of the support oil cylinder require professional technical personnel to operate. In addition, the safety risks during the construction process are relatively high, and effective safety measures need to be taken to ensure the safety of construction personnel.

Environmental factors impact

Environmental factors such as temperature, humidity, and groundwater level may also have an impact on the performance of the support oil cylinder. For example, in high temperature environments, cylinder seals are prone to aging and failure; In high humidity environments, oil cylinders are prone to rust and corrosion; The change in groundwater level may also cause changes in the buoyancy of the oil cylinder, thereby affecting its stability.

2、 Solution

Strengthen geological exploration and monitoring

Before excavation of the foundation pit, a detailed geological survey and monitoring should be carried out to understand information such as geological structure, groundwater level, rock mechanical properties, etc., providing scientific basis for the design and construction of the support oil cylinder. Meanwhile, during the construction process, changes in geological conditions should be monitored in real time, and the support plan should be adjusted in a timely manner to ensure the stability and safety of the support oil cylinder.

Choose the appropriate support cylinder model

Select the appropriate support oil cylinder model based on geological conditions and construction requirements. For example, in soft soil areas, oil cylinders with larger bearing capacity and better stability can be selected; In hard rock areas, oil cylinders with higher stiffness and smaller deformation can be selected. At the same time, it should be ensured that the sealing performance and corrosion resistance of the oil cylinder meet the engineering requirements.

Improve construction technology level

Strengthen the training and technical exchange of construction personnel, improve their professional skills and safety awareness. During the installation, debugging, and use of the support oil cylinder, it is necessary to strictly follow the operating procedures to ensure construction quality and safety. At the same time, a sound construction management system should be established to strengthen quality control and safety supervision during the construction process.

Take effective environmental protection measures

Effective environmental protection measures should be taken to address the impact of environmental factors on the performance of support cylinders. For example, in high-temperature environments, cooling measures should be taken to reduce the working temperature of the oil cylinder; In high humidity environments, anti-corrosion and rust prevention measures should be strengthened for oil cylinders; In areas with significant changes in groundwater level, measures such as drainage or grouting should be taken to reduce the impact of groundwater level on oil cylinders.

In summary, the application of support oil cylinders in complex geological conditions faces many challenges. However, by strengthening geological exploration and monitoring, selecting appropriate support oil cylinder models, improving construction technology, and taking effective environmental protection measures, these challenges can be effectively addressed to ensure the safety and smooth progress of foundation pit engineering.
