What is excavation support? Analysis of construction safety and common support types

What is excavation support

Excavation support (shoring) refers to the use of structural braces or materials in excavation projects tosupport the soil wallto prevent soil collapse and damage to surrounding structures. Its main purpose is to ensure the safety of excavation operations and prevent collapses caused by unstable soil.

The key technical principle of support

During the excavation process, the soil on both sides of the excavated trench or pit is prone to losing balance due to gravity or external forces, leading to shaking or collapse. The support system disperses static or dynamic soil pressure onto a sturdy structure through physical connections, effectively preventingsoil wall deformation or collapse, protecting on-site workers and equipment.

How to prevent collapse and accidents

• Securing the soil wall structure: Supports or columns 'fix' the surrounding soil to prevent loosening.
• Dispersed pressure: Distributes the natural downward force of the soil to the support, reducing soil movement.
• Reduce vibration impact: In areas near traffic or construction equipment, supports can absorb or slow down vibrations that cause structural damage.

Excavation support is not just an engineering aid, but also a safety measure for excavation.The first line of defenseProper support can prevent serious construction delays, financial losses, and even fatal accidents, making it an indispensable safety measure in every excavation project.

Why support is so important in excavation projects

In excavation projects, in Taiwan,shoring is not only a basic safety measure but also a key to ensuring smooth and legal construction. The following three aspects illustrate the importance of support:

Ensuring the safety of workers and equipment

During excavation, soil may collapse due to groundwater, soil loosening, or external forces, posing serious threats to workers and construction equipment.A good support system can effectively prevent wall collapse and reduce accident risks.Ensuring the safety of on-site personnel and the integrity of machinery, avoiding unbearable economic losses.

Complies with local building regulations and engineering standards.

All counties and cities have clear regulations on construction safety and soil support, especially in urban areas or underground public facilities construction, which are more stringent.Proper use of support systems can ensure the project complies with the Building Code and local government safety standards.To avoid violations leading to penalties or work stoppages, ensuring the legal operation of the enterprise.

Reduce project delays and construction costs

Cave-in walls not only threaten safety but also causeWork area sedimentation backfill, equipment maintenance, and even secondary excavationSignificantly delay progress and increase labor and material costs. Using appropriate support methods can stabilize soil conditions and improve construction efficiency.Avoid rework, saving time and expenses。

In the confined construction sites, especially suitable for flexible construction with small excavators (such as HY Excavator models 0.8 to 2.0 tons), combining effective support techniques to enhance safety and efficiency. For contractors aiming to reduce safety risks and control costs, this is an indispensable investment.

Common types of excavation support and excavation support techniques

InExcavation support (shoring)Choosing the right support system is crucial because it directly affects site safety and project efficiency. The following are some common and practicalexcavation support systemsthat are also frequently used in construction sites.Excavation support technology。

Hydraulic Shoring

Hydraulic shoring uses hydraulic cylinders to generate strong thrusts, supporting the soil wall and preventing collapse. This system is quick to install and adjustable, especially suitable for sites with limited depth and space. Hydraulic systems can greatly improveExcavation safety measuresand shorten construction time.

Wood shoring

Traditional timber supports are still widely used, especially in small or shallow excavation operations. Timber is inexpensive and readily available, but installation and removal are time-consuming, and it is not suitable for long-term or heavy-duty operations. To ensure safety, regular inspection of timber condition is necessary.

Pneumatic Shoring

Air pressure support also uses compressed air to open the support frame, suitable for quick support of medium to shallow excavations. This method is easy to install, lightweight, and especially suitable for urban excavation projects with limited space, making it a good choice for small to medium-sized projects.

Aluminum Hydraulic Shores

Aluminum hydraulic shores combine the lightweight of aluminum with the powerful hydraulic thrust, suitable for sites requiring frequent movement or confined spaces. This system is becoming increasingly popular in the United States because it shortens construction time, reduces labor burden, and improves overall construction efficiency.

Steel Sheet Piling

Steel sheet piles are commonly used in large-scale excavation projects, forming a continuous wall by inserting steel sheets into the soil to stabilize the soil and isolate groundwater. Although more expensive, they are very durable and suitable for long-term operations and deeper excavations.

For most small to medium-sized construction sites, we recommend usingHYExcavator small excavatorhydraulic or pneumatic supports, which ensure both efficiency and safety, complying with strictexcavation safety standards。

support installation and use during tunneling operations

Basic process and key points of support installation

In excavation projects,support system (shoring) is crucial to prevent soil collapse. The installation process typically includes:

• Site assessment: determining soil quality, depth, and surrounding environmental conditions.
• Design and Selection: Choose the appropriate support type based on on-site conditions (such as hydraulic supports, wooden supports, aluminum supports, etc.).
• Placement of Support Structure: Install the support frame upright in the trench or excavation edge according to the design dimensions.
• Fixation and Pressurization: Use hydraulic or pneumatic systems to ensure the support frame is secure, enhancing soil stability.

The correct installation process not only prevents slope collapse but also enhances overall operational safety, avoiding accidents.

The role of small excavators in support installation

For most urban areas or confined construction sites,small excavatorsit is a good helper to improve support installation efficiency. Its advantages are:

• Flexible operation: suitable for narrow spaces, able to quickly position support materials.
• Precise placement: capable of accurately placing large or heavy materials, shortening construction time.
• High compatibility: Compatible with hydraulic or pneumatic support systems, quickly adjusting fixed positions.

For example, the HYExcavator series of mini excavators, weighing 0.8 to 2.0 tons, designed specifically for construction sites, becoming an indispensable tool in support operations.

Common support application scenarios

Most excavation projects use supports based on different needs, especially in the following situations:

• Excavation of trenches exceeding safety standardsAvoid the danger of wall collapse.
• Loose or water-rich soil.Increase the stability of excavation sites.
• Construction sites near buildings or pipelines.Prevent ground displacement from damaging surrounding facilities.
• Heavy equipment frequently entering and leaving the site.Ensure operational environment safety.

In the above scenario, using appropriate support systems and small excavators not only effectively safeguards workers but also accelerates project progress and reduces costs.

In summary, the installation of excavation supports must be combined with soil conditions, project requirements, and mechanical assistance to achieve optimal safety and efficiency.

Safety precautions and best practices for excavation support

In excavation projects,Support structure (shoring) safetyis key to preventing collapses and accidents. Proper safety management not only protects workers and equipment but also compliesConstruction safety regulationsto avoid project delays and economic losses.

Assessment of excavation support front site

• Comprehensive evaluation of soil and terrain conditions: Understanding soil type, water content, and underground structures is the basis for selecting the appropriate support system. When soil is unstable, support strength must be reinforced.
• Inspect on-site space and equipment entry and exitEnsure that the mini excavator and support equipment can move in and out smoothly to minimize operational interference.
• Predict potential risk areassuch as near buildings, pipelines, or roads, and design appropriate support plans to enhance protection.
