Protection structures of sea- breaker (tetrapod, quadric-pad, and three bars)
Breakers are wall structures which produce a calm laver by depreciation of wave power at beach. The calm environment may be used by breaker arms for jetty, porterage and secure operation of floats and also protection of port facilities. In addition of above mentioned cases, breakers may control flow of sedimentation by improvement of entrance conditions of ports and direction of marine flows and creation of various balances of water flow.
Types of breaker:
There are two main breakers: mass and bulwark
It has different types such as natural stone, concrete blocks and a combination of stone and concrete blocks. Concrete forms such as tetrapod, acropod, quadric-pod, and three bars are used in this type. Many samples of tetrapod, etc. have been produced in Parsian Ghaleb Industrial Group and performed at northern beaches.
New Jersey is a concrete obstacle for directing vehicle. They are manufactured in prefabricated concrete pieces connectable to each other and act as return director while strike of vehicle side and decrease damage. This device is used as a guard for pedestrians, protect from civil project workers against vehicles, provisional obstacles and security obstacles, and also dam, prevention from fire distribution in forest, river director, and making roads in several lines.
Culvert is a channel which is used for directing water of a channel or sewage from one side of hill to another side. Culvert is a structure which is made at the lowest point of depth line. Culverts under waters are water pipes which their length is more than width of road. There are various methods for culver manufacturing and concreting. Coverage of culvert may be molded by modular molds of Parsian Ghaleb. Another way is to manufacture a special mold suitable for the dimensions of culvert which is able to be displaced by hydraulic equipment for several concrete steps. This type of mold is designed and manufactured based on considered plan of executer in Parsian Ghaleb industrial group. Another ways is to manufacture a special mold for providing prefabricated concrete pieces based on dimensions of culvert. All options may be negotiated by us.
Modular ascending system
This method is proposed for most structures which have little and limit formwork capacity due to rapid and inexpensive execution and also use of modular formwork system.
In this system, a rigid solid panel is made by using flat panels and their connection to each other by pipes and soljers which is easily installed at height by lift.
