Shoring Systems (KRINGS)

Parallel shoring

Heavy-duty yet smooth-running, the high-strength PV (parallel shoring) system simplifies operations by fixing the vertically mobile carriage at the position required for effective load discharge. The carriage keeps the slide-rails aligned absolutely parallel and enables the carriage and the individual panels to slide smoothly with little friction. This principle pays off particularly during removal. The panels can also be withdrawn without difficulty from great depths. The carriage is available in rectangular and U-versions, with the latter achieving greater vertical clearance and even better structural loading values.

Robust yet smooth-running, the high-strength EG PV (parallel shoring) single-rail system greatly simplifies operations. The fixing of the vertically displaceable carriage in the position required for stability ensures that loads are discharged effectively at just the right point. The absolutely parallel alignment of the slide-rails enables the frame and the individual panels to slide smoothly, which pays off particularly during removal.

The system is suitable for constructing cast-in-situ concrete sewers. Once the concrete has set, the concrete base slab braces the base of the rails. The carriage can then be raised to the top to create sufficient working space for sewers up to 3 m high. To cater for greater trench widths, the carriage can be widened by adding flanged extension bars.

KRINGS Single slide-rail inner-city parallel shoring

KRINGS Single slide-rail inner-city parallel shoring

During urban trenching operations, pipes and cables crossing the trench are commonplace, which rules out the use of large-area shoring systems. A cost-effective and versatile solution in such cases is inner-city parallel shoring that combines the beams and carriages of parallel shoring with DKU universal piling frame elements for guiding sheet piles.

Shoring module installation and pile insertion are performed largely without causing vibration – an important aspect of excavation work in inner-city locations where roads and buildings are often in the immediate proximity of the trench.

Basic data

  • Module length: 2.77 m / 4.27 m
  • Length slide rail: 4.00 m
  • Height sheet pile element: 1.00 m
  • Length sheet piles (KD VI/8): variable

KRINGS Double slide rail system, parallel shoring, DG PV

KRINGS Double slide rail system, parallel shoring, DG PV

Identical to the EG PV single slide-rail system, the DG PV double sliderail system meets the highest standards of economy and flexibility. The carriage is available in rectangular and U-versions. This system thus creates far greater working space than rival systems. The carriages are vertically displaced in accordance with the manufacturer’s structural loading specifications. This means they can be fixed in the desired installation position for optimum load discharge. At the same time, the boogie car also ensures that the slide-rails are kept absolutely parallel.

When constructing in-situ concrete sewers, the carriage can be raised right up as soon as the concrete base slab has set. This creates the greatest possible working space, permitting the construction of sewers up to 5.0 m high. To cater for larger trench widths, the system can be widened by inserting flanged extension bars.

Basic data

  • Shoring depth: max. 7.00 m
  • Pipe culvert height: variable
  • Panel length: 2.00 m – 7.00 m
  • Height base panel: 2.32 m
  • Height top panel: 1.33 m

KRINGS Corner post EG Eck / DG Eck

KRINGS pit shoring consists of a small number of highly effective shoring components with which shoring solutions for practically any type of pit can be realised – regardless of its size, depth or shape. Special corner slide-rails and the proven shoring panels form a self-contained, versatile system for securing shaft walls.

The slide-rail system pits can be used in many different ways, such as for launch and reception pits for pipe jacking and also for tank pits, manholes and construction pits as bored pile shoring, and other excavation projects.

Basic data

  • Shoring depth: max. 5.50 m
  • Panel length: 2.00 m – 7.00 m
  • Height base panel: 2.32 m
  • Height top panel: 1.30 m

Double slide rail system, parallel shoring, DG FP

Double slide rail system, parallel shoring, DG FP

The DG FP double slide-rail version with the sprung socket is the logical further development of the box system into a guided overlapping shoring system, i.e. slide-rail shoring forming a self-contained overlapping system. Slide-rail shoring is designed among other things for loose soils and can therefore only be installed using the dig-and-push method. In the FP version the sprung socket is attached directly to the slide-rail and positioned in the grid of holes dictated by the needs of load discharge.

The world's best-selling slide-rail system is based on the first sliderail shoring of the seventies. This patented dual-chamber shoring system uses the principle of shoring panels sliding past one another. During removal, relatively low pulling force is therefore required because the panels can be withdrawn individually. This makes the use of a medium-size excavator possible. Ideal trench depths: 4 to 6 m.

Basic data

  • Shoring depth: max. 7,40 m
  • Pipe culvert height: max. 1,50 m
  • Earth pressure: max. 23,85 - 55,80 kN/m²
  • Panel length: 2,00 m - 7,00 m
  • Height base panel: 2,32 m
  • Height top panel: 1,30 m

KRINGS piling frame element BLU

KRINGS piling frame element BLU

Just like the large DKU piling frame element, the smaller BLU variant is a low-deformation, universal and cost-effective trench shoring method particularly suitable for inner-city applications with pipes and cables crossing the trench. The piling frame element that serves as the upper guide for the piles introduced vertically into the ground is ideal for the laying of gas and water pipes and other service lines. In the dig-and-push process, the digger pushes the piles into the ground immediately after excavation, causing little vibration.

The assembly and prior adjustment of the piling frame element are similar to that of edge-supported shoring systems. The support brackets can be used in two different ways. For use in the trench, the support brackets are attached to the top of the element. If used outside the trench, the brackets are attached to the bottom of the element. KRINGS spindle systems are used as supporting elements.

GIGANT aluminum lightweight shoring

GIGANT aluminum lightweight shoring

GIGANT aluminum lightweight shoring is the ideal solution for trenches in urban areas. The modular system is made of aluminum and closes the gap between steel systems, which are frequently too heavy, and timber planks. The range is divided into several areas, in order to cater for the varying requirements of today’s construction sites. The modular system can be combined and supplemented as required.

The lightweight sections (max. 43 kg) can be brought to the site with a small commercial vehicle or trailer. The aluminum boards can then be quickly connected by hand on site using aluminum couplers to form a shoring unit of the desired depth. All conventional trench widths and depths < 6 m and degrees of difficulty (transverse electrical lines, non-cohesive soils, tight working areas) can be handled using the standardized aluminum lightweight GIGANT shoring, even without heavy equipment. The free working area between the sewer struts of up to 2.85 m, trench widths of up to 2.26 m and a pipe culvert height of up to 2.80 m leave plenty of space for excavation and pipe laying work. The system is ideal for laying cables as well as gas and water lines in open construction, creating launch and reception pits for underground pipe and cable laying, installing and maintaining house connections, inspection work, landscape gardening, and a whole host of other purposes.

Basic data

  • Installation depth: max. 6 m
  • Trench width: max. 2.26 m
  • Weight: 43 kg (per component)

KRINGS Dragbox

KRINGS Dragbox

The mobile trench box for open terrain

In addition to the KRINGS trench boxes designed for the familiar processes of placement in the finished trench or dig-and-push, there are also Drag Boxes. This type of trench box is widely used in the USA, for instance, and is enjoying growing popularity in Germany because of its many advantages for certain projects and conditions.

The Drag Box has cutting edges at its front end (in the pulling direction). The dimensions of the panel are adapted to the needs of the project. Due to its especially rugged construction, large pipe clearances are also possible. The dimensions are limited only by the performance range of the hydraulic excavator employed.

The panel length should offer space for twice the pipe length, i.e. the average length of the Drag Box is approx. 4.0 m to 5.0 m. As it is pulled by an excavator in the direction of sewer installation, the usual processes of placement and lowering, storage at the side of the trench and re-placement can be dispensed with. The Drag Box is shifted as the trench advances, i.e. the excavator employed shifts the box into its new position after pipe-laying and partial backfilling.

The main applications are sewer construction projects in open terrain. This type of shoring is particularly cost-effective if there are no or few pipes or cables crossing the trench. Pipes are laid solely within the protective confines of the Drag Box, so staff working in the trench enjoy maximum safety.

Further information on the Drag Box is available on request.

KRINGS Sheet pile element KKP (before 092009)

KRINGS Sheet pile element KKP (before 092009)

This rapid, cost-cutting shoring system (also known to experts as vertical shoring) is the inner-city complement to proven large-area steel shoring. Particularly in sections frequently crossed by pipes and cables, this type of shoring has a large number of economic advantages combined with its extreme ease of use. With dig-and-push installation by a digger at the end of the trench, efficient operations are assured even in busy streets and confined spaces.

The use of existing shoring components from the rest of the KRINGS product range helps to cut costs considerably. The strut elements are compatible with large-area steel shoring. Its combination with large-area shoring in sections without crossing pipes and cables is also highly economic. For this purpose, the frame panels are fitted at the ends with guide profiles for insertion in slide-rails.

KRINGS Sheet pile machine DPV

KRINGS Sheet pile machine DPV

The KRINGS DPV pressed-pile shoring system was designed for the construction of new and modernisation of existing sewers and drains in narrow streets with buildings in the immediate vicinity. It can be used safely and inexpensively in all soils. Unlike conventional, linear sewer trenches, the DPV method involves a moving trench which is only open at the point where the sewer pipes are actually being laid.

This point-based approach reduces the volume of excavated soil considerably and minimizes the risk of subsidence. A shaft shored on all sides and with the length of the DPV unit is excavated down to the base of the sewer trench. The sheet piles are hydraulically pressed in while the trench is being dug. The trench walls are securely shored with sheet piles and walers. If the trench is crossed by cables or pipes, the sheet pile in question is locked in position above the cable or pipe while the other sheet piles are pressed past the obstacle into the ground.

Basic data

  • Shoring length: 5.50 m / 6.70 m
  • Shoring width: 1.00 m – 3.00 m
  • Shoring depth: 4.50 m / 5.50 m
  • Pressing force: 7.65 t / 9.00 t
  • Number of sheet piles: 14 pcs. / 18 pcs.
