Moselle Lock, Trier, Germany

Formwork, scaffolding, engineering: PERI supported site operations with a project-specific formwork and scaffolding concept.
From intake to outlet structure, the new, second lock has a total length of 312 m.
For realizing the Moselle Lock in Trier, around 45,000 m³ of concrete was processed during the construction period of almost 1.5 years.
The SCS Climbing System served as scaffolding for the 7.80 m high VARIO GT 24 Girder Wall Formwork for the second concreting cycle height.
The formwork carriage for the efficient construction of the longitudinal channels was also project-specifically planned right down to the last detail and assembled at the company´s assembly hall using PERI system components as far as possible.
A PERI supervisor supported the construction team on site to ensure efficient use of the formwork and scaffolding systems from the very start.
Example intake funnel: precisely manufactured and verifiably proven 3D boxed elements from the PERI formwork assembly facility made it possible to realize complex building geometries.
The lock structure to be constructed at a depth of 15 m had massive component dimensions and a high level of reinforcement.
During the construction of the Moselle Lock in Trier, a PERI project coordinator supported the site management in all technical, commercial and logistical aspects regarding the coordination of the planning and installation work as well as ensuring punctual supply of materials.
An important element of individual project support is the formwork assembly. PERI uses state-of-the-art machines to produce cut-to-size plywood sheets and all types of special formwork.
The formwork and reinforcement work in particular presented a major challenge. The main issue here was taking into consideration a large number of mounting components with extremely tight tolerance specifications.

Project data

Location: Trier, Germany

  • New, second Moselle lock with a total length of 312 m from intake to outlet structure
  • Positioned next to the existing 170 m long lock facility, the new lock chamber is 216 m long and features a usable width of 12.60 m and a height of 12.70 m
  • Filling and emptying by means of longitudinal channels on both sides together with transversely-positioned branch channels
  • Large-scale jobsite whereby around 45,000 m³ of concrete was processed during the construction period of almost 1.5 years

Requirements

  • Reinforced concrete structure with massive component dimensions and a high level of reinforcement, realized at a depth of 15 m within bored pile walls
  • Demanding construction project whereby numerous mounting parts and strict tolerance specifications had to be taken into consideration
  • In particular, the formwork and reinforcement work presented a major challenge

This construction site is yet again another highlight for me. The lock facility was a demanding construction project whereby numerous mounting parts with very tight tolerance specifications had to be considered. The coordination was perfect: PERI supplied the formwork elements completely prefabricated - and there was no component that didn´t fit. My appreciation goes out to all PERI engineers who worked with us with their high level of technical understanding – a big thank you. The collaboration could not have been better.

PERI solution

  • Comprehensive overall solution with a project-specific formwork and scaffolding concept based on close cooperation with the project management
  • Pre-fabrication of all recess units and timber formers at PERI´s assembly hall; these were used, for example, for intake funnels, gate recesses and floating bollards – designed for providing efficient striking operations as well as ensuring reusability.
  • Just-in-time deliveries of precisely pre-fabricated formwork elements – quantities and timing matched to construction site requirements
  • Comprehensive, continuous on-site support
  • PERI project coordinator for coordinating the planning and assembly work as well as ensuring punctual supply of materials
  • PERI supervisor for briefing site personnel on the correct and safe handling of the systems and special formwork used in the project
