AP BT4-8 inverted siphon-dam hybrid structure

SURFACE WATER CONTROL: AN INTEGRATED SOLUTION FOR CROSSING CHANNELS AND WATER FLOWS

In case of expansion and development of surface water management systems, it may be necessary to solve the crossing of canals and watercourses.

AQUAPROFIT Co. has developed this concealed structure combined with a dam for such cases. The concealment structure is integrated on the upstream side with a tilting dam structure like an ear shaft.

D 1.800 mm bújtató és távműködtetésű, vasbetonfalas duzzasztó kombinált műtárgy, a vízpótló Főcsatorna átvezetése a Korcsina csatorna alatt (Lakócsa, Ős-Dráva projekt)

D 1.800 mm inverted siphon and remote controlled, reinforced concrete siphon-dam hybrid structure, transitioning the water replacement Main Channel under the Korcsina canal (Lakócsa, Ancient-Dráva Project)

The lower plane of the base plate of the two structures is the same. The front wall of the concealed structure is made up of remaining sheet piles, which are folded down to the upper plane of the base plates on the influence side. These battens also provide an extension of the leak path.

The battens are closed by a monolithic reinforced concrete beam on the upper plane of the structure. The front wall of the ear shaft receives the prefabricated reinforced concrete pipe of the weir. The inner diameter of the reinforced concrete pipes is 1600 mm. The element connected to the ear shaft is formed with an angular break, thus tilting the water to be passed through the enclosure under the bed of the crossed channel.
