Precast concrete tunnel segments: purpose and application

Concrete elements of a tunnel can be called ‘sewer tunnel segments’, ‘shield tunnel segments’, ‘high-precision concrete segments’ or ‘precast concrete tunnel segments’.

Precast concrete tunnel segments are used for the reinforcement of underground facilities (tunnels, sewer lines, mine shafts) built in urban areas, laying of underground utilities, and construction in harsh hydrogeological conditions.

Round tunnel segments that are connected into a single concrete ring are the most popular ones. Precast concrete tunnel segments are connected with tie rods and equipped with rubber gaskets, which ensure leakproofness of the structure in the course of the construction of the tunnel.

The segments of a ring are connected through concave-convex pipe ends, which do not break even during opening.
Depending on the purpose of the tunnel, segments’ dimensions will vary.

Steel moulds for precast concrete tunnel segments by M-Konstruktor

The M-Konstruktor plant manufactures steel moulds for precast concrete tunnel segments. One mould can be used for the production of 8 tunnel elements, which form a single segment of a tunnel pipe.

At your request, we will manufacture moulds for precast concrete tunnel segments of required diameters and dimensions.
A steel mould is equipped with core drivers that are used to create hollows in the concrete product, which allow the consolidation of the elements into a single structure.

The mould’s hinged sides make the finished concrete products demoulding process much easier.


Developed in-house
The M-Konstruktor plant offers manufacturing of steel moulds for reinforced concrete products proprietary designed in accordance with applicable technical requirements.
High Quality
In-process monitoring at every step of the steel moulds manufacturing allowing to guarantee its proper quality.
Easy demoulding
Steel moulds are equipped with hinged sides for easy demoulding. M-Konstruktor steel mould locks are fixed with external hexagon nut allowing to use pneumatic or electrical nut runner. That makes demoulding to go faster. The package also include the torque link with openings for catbar which makes operation more convenient.
