Lining with pipe jacking
Pipe jacking process: installation and coating
The Reinforced concrete pipe driving permite instalar tubos en subterráneo sin necesidad de abrir zanja, mediante sistemas de empuje hidráulico y guiado láser desde un pozo de ataque. Este método es ideal para zonas urbanas, cruces ferroviarios o carreteras, donde las excavaciones abiertas no son viables.
Durante la ejecución, se inyectan fluidos como bentonita o polímeros para facilitar el empuje, reducir la fricción y estabilizar el terreno. El resultado es una instalación rápida, precisa y segura, con mínima afección en superficie.

Pipe types and pipe driving techniques
En función del terreno, diámetro y uso final, se emplean distintos tipos de tubería:
Hormigón armado, por su resistencia estructural y durabilidad.
Gres vitrificado, ideal para redes de saneamiento.
Acero, en suelos inestables o cruces especiales.
Durante el proceso se puede aplicar mortero de trasdós para estabilizar el tubo, y usar métodos auxiliares como el empuje guiado, escudo cerrado o guiado automático.
Este tipo de instalación está regulada por la ASTM D2321, normativa internacional para la colocación estructural de tuberías en obras subterráneas mediante métodos sin zanja.

What is pipe ramming and how is it performed?
The pipe ramming is a process in which prefabricated cylindrical pipes are installed in a subway tunnel. It is carried out by pushing the pipes from an attack shaft, using thrust cylinders that transfer the stress to the tunnel boring machine located at the face. During installation, bentonite or polymers can be injected to reduce friction and facilitate advancement.
What are the types of pipes used in ramming?
In the pipe rammingDepending on the project and soil conditions, various types of pipes are used. The most common include the reinforced concrete pipeThe most common types of pipes are the steel pipe, the polycrete or polyester resin pipe, and the ceramic or stoneware pipe. Each type of pipe is selected according to its characteristics and the required resistance.
What role do intermediate stations play in pipe ramming?
The intermediate stations in the pipe ramming are installed in long lengths to distribute the thrust stresses over several pipe segments. These stations help maintain process stability and reduce the risk of pipe deformation or failure, especially in long projects.
How is the tightness of the pipes ensured during installation?
Each drive pipe is fitted with a gasket on the nozzle to ensure a tight seal. watertightness. In addition, a "dolly" is incorporated into the pipe tail to absorb irregularities and facilitate a secure joint between the pipes, preventing leaks and ensuring efficient integration with the concrete.
What is the microtunneling or closed shield technique and how is it applied?
The microtunneling or closed shield technique is a method of subway excavation that uses a closed shield tunnel boring machine to perform excavation and lining simultaneously. This technique is ideal for difficult conditions and is used to install pipelines in tunnels with high precision and control.
What safety measures are taken during the pipe driving process?
During the pipe rammingIn addition, several safety measures are implemented, such as constant monitoring of ground conditions and equipment, regular maintenance of machinery, and training of personnel. Support and stabilization systems are also used to prevent problems during installation and ensure a safe working environment.
