📋 Tender Overview
Have you seen the water ballet in the construction pit at Groningen station To make the new pedestrian passage we have to go into depth. That is why contractor Strukton is working on a wet excavation of the second construction pit.A construction pit full of waterThis construction pit can be found directly behind the station building and is called phase two. In order not to disturb the bottom of the construction pit and to ensure that the cockpit remains stable we fill the tub with water. Pontoons float in the water. These are special platforms on which excavators are located. These excavators suck sand and silt from the soil. The construction pit will eventually be slightly deeper than ten meters below sea level.The hose with the nozzle remains at the surface of the water with the help of floats. The sand and silt are pumped through pipes to the ground depot on the construction site. To maintain the water level water is continuously supplied from the Hoornsediep.Pouring drilling and braidingA little further south work is still underway on the future bus station of Groningen. This bus station will consist of two bus decks with the platform in the middle. Over the past month concrete has been poured into the northern bus deck. The reinforcement is still being worked on on the southern bus deck. Reinforcement is a technical reinforcement that is applied in a structure or in building material in this case the concrete. The reinforcement work takes a long time and is done in stages. Every time a piece is finished cuttings are drilled to further expand the concrete structure.Braiding reinforcement is hard work. All steel bars are braided together by hand. To make the work a little easier the steel is already delivered in the right shape and length. The steel weavers weave the reinforcing steel together on site into a large reinforcement network.
