BOX SHORING AND TRENCH SHORING - SHORING SYSTEMS AND ACCESSORIES FOR TRENCH SHORING FROM TERRA INFRASTRUCTURE

Shoring systems have become an integral part of civil engineering projects. Even if every construction site has specific challenges that need to be overcome, the basic requirements for shoring are always the same: high safety thanks to stability, minimal impact on the ground outside the shoring and the largest possible working areas with sufficient space, regardless of the trench width and shoring depth. Preventing a collapse ensures the safety of employees and surrounding structures. What began in 1949 with the founding of the company by Emunds and Staudinger in connection with the securing of coal mines, today comprises an extensive product range with slide rail shoring, trench boxes and plank chamber shoring of the product brands E+S and KRINGS, which are united under the umbrella of terra infrastructure.

The introduction of trench shoring systems has fundamentally changed work in civil engineering. Where workers previously had to reckon with collapses due to vibrations, soil or traffic loads, soaking or drying out, today our products, which are tailored to the individual application, support the trench and excavation walls safely and reliably. Accidents and structural damage can be prevented in this way.

SAFETY HAS THE HIGHEST PRIORITY - TRENCH SHORING FROM E+S AND KRINGS

However, construction site equipment today is not only safer and of higher quality than in the second half of the 20th century. Nowadays, we pay particular attention to resource conservation and sustainability by using recyclable systems. A lot has happened in 75 years of trench shoring. Safety is still our top priority. But as individual as the project is, the requirements today are just as specific. That's why we offer our customers a wide range of systems from E+S and KRINGS. Whether it is the E+S linear and box shoring for demanding construction projects with very large and wide excavation pits, or a versatile box system from KRINGS, which takes up very little space for storage and transportation: The right solution can be found for every application in terms of economy and process technology.

UNIQUE IN THE WORLD

Within our product range, the linear shoring system stands out in particular with its high performance and versatility, especially when securing excavations with large widths and depths. E+S linear shoring is a globally unique method in which rigid carriages keep the beams and thus the shoring panels at a distance. Everything runs linearly - always at the same distance from the opposite side. This ensures more effective, faster and noticeably more economical work. A major advantage of the system results from the special design of the beam. It allows the shoring panels to be swung in from the side.

Innovations in the area of our shoring systems can also be expected in the future. We are continuously developing our systems in line with the growing requirements on construction sites. This contributes to safe and economical construction processes that can be implemented quickly and to the complete satisfaction of everyone involved.

IT ALL STARTED WITH SAFETY IN COAL MINES

When Josef Emunds and Günter Staudinger founded the company of the same name in 1949, they initially specialized in safety products for underground mining in coal mines. The experience and knowledge they gained here helped them when the coal mining industry went into crisis and Emunds+Staudinger (E+S) developed the first steel shoring element that could be used as a trench retaining wall in underground construction. In 1964, the civil engineering trade association issued the first official approval for steel shoring elements as a safety device for civil engineering. E+S continued to work on improvements. Constantly increasing demands on the quality and performance of the material used led to the development of reusable complete systems that could be adjusted to different trench widths and installed at different trench depths in just a few simple steps. Large-area steel shoring became increasingly important. These are load-bearing hollow steel profile walls that are held at a distance with adjustable spreaders and form a shoring box.

TERRA INFRASTRUCTURE: CONCENTRATED SHORING EXPERTISE UNDER ONE ROOF

In 2004, E+S took over the rental and sales business of its competitor KRINGS. Today, both brands are united under the terra infrastructure umbrella. This provides customers with concentrated shoring expertise that can be used to master the specific challenges of each individual construction site. Regardless of the trench width and shoring depth, the various systems all meet the most important requirements: high safety through stability, low impact on the ground outside the shoring and the largest possible working spaces. The objectives have remained the same for 75 years. At that time, however, nobody dared to dream of today's technical possibilities and the variety of product solutions.

HOW DO PROP AND SECURE THROUGH SHORING WORK?

Shoring is an important structural measure in civil engineering and geotechnics that is used to ensure the stability of trench and excavation walls and to secure them. It is often used to prevent soil from slipping and to increase the safety of construction sites:

1. planning and design:

Before starting to secure a trench or excavation, careful planning of the construction project is necessary. Engineers analyze the ground conditions, the trench depth and the surrounding conditions. On this basis, a decision is made as to which type of shoring should be used.

2. types of shoring:

There are different types of shoring, including:

Box shoring
Slide rail shoring
Sheet pile shoring

The choice of system depends on various factors, including the depth and width of the trench, the type of soil, water conditions and the duration of use.

3. execution:

Site preparation: The site is prepared by clearing the area and creating access routes where necessary.

Installation: Before the shoring is installed, the selected system is pre-assembled in full or in parts. Sufficient space must be provided on the construction site for installation.

Installation of the shoring and excavation: The selected shoring is installed. Depending on the system, this may require different techniques and equipment. The trench is excavated taking into account the planned depth and width. Depending on the soil conditions and the selected shoring system, the excavation is carried out either before or parallel to the installation of the shoring system.

4. monitoring and maintenance:

During construction, continuous monitoring of the stability of the shoring is required to ensure that no settlement or movement occurs. This can be done by regular inspections and the use of measuring instruments. Adjustments may need to be made to ensure safety.

5. final work

After completion of the construction work, the shoring elements are dismantled, unless they remain permanently.

WHAT IS THE TYPICAL APPLICATION OF TRENCH SHORING?

The most common applications in construction and geotechnical engineering include

Excavation pits and trenches: Trench shoring is used during construction to stabilize walls and prevent soil slippage. This is particularly important in urban areas where space is limited and neighboring structures need to be protected.
Infrastructure projects: When laying pipes, tubes or cables, shoring systems such as trench boxes are often required to secure the trenches and carry out the work safely.
Road and path construction: In the course of this construction work, pipes and drainage systems are often laid that require temporary securing using trench shoring systems.
Sewer and pipe renovation: When renovating or replacing old or damaged pipes, sewers or lines, shoring systems are required to secure the excavation pit.
Environmental and remediation projects: When remediating contaminated soils, shoring can be used to simplify soil excavation and thereby contain the spread of contaminants.
