Tunnel Forms Formwork
Implementation of buildings consisting of walls and slabs using tunnel shapes
Tunnel Forms Formwork is used in building structures which are both from walls and slabs. They are designed somehow in which half of each slab with its adjoining wall and two integrated formworks become mantled as an L-shape all at the same time. After reinforcement, concrete is poured. The location of mechanical and electrical installations can be anticipated in this system and the formworks get opened and closed uninterraptedly. Mantling by a crane is done in a minimum time.
Tunnel formworks are used for lining channels, shafts and deviational tunnels. Tulle-shaped forms, in terms of assembling and disassembling, are categorized in two parts:
- Hydraulic forms
- Mechanical forms
In hydraulic forms, assembling and disassembling segments of form is carried out through using hydraulic jacks while in mechanical forms, it is carried out through suing manual or hydraulic jacks. Usually, in large segments, hydraulic system is used and this is due to heaviness of segments. Using hydraulic in small forms is a very hard task technically while in inner parts form of tunnel will create limitation.
The formwork of a prefabricated part is designed and manufactured somehow that it can be used for numerous numbers of times in addition to its simple opening and closing. Therefore, the stability of these formworks should be highly valued at the designing stage. These formworks are often heavy and have huge dimensions and so cranes are used for operating them.
The advantages of Tunnel Forms Formwork:
What is tunnel molds formwork?
Tunnel molds are divided into two groups in terms of opening and closing:
- hydraulic molds
- Mechanical molds
In hydraulic molds Opening and closing mold segments using hydraulic jacks and in mechanical molds using manual jacks Or oiled.
The hydraulic system is usually used in large sections and this is due to the weight of the segments.
The use of a hydraulic system in small molds is technically difficult and will not limit the internal parts of the tunnel mold
- You can specify the thickness, dimensions, surface , materials and style because we can do it
