By presenting the Award the EA CR appreciated the design and execution of the bridge structure which with its range, geometric parameters (length of spans, height of pillars)

and procedure of building of a unique bridge structure designed with application of several calculation models which made it possible to create a materially balanced

and slender structure which is an evidence of the high level of bridge engineering in the Czech Republic.

 

The structure of the bridge is fitted with permanent stable points, which during building made it possible to perform measurements and monitoring of the geometry

of the bridge serving for the calibration of models with respect to the real effects of the final shaping of concrete on the behaviour of the structure. It is also fitted with

tensiometers for  long-time monitoring of the behaviour of the bridge structure during building and operation and allows calibration of contemporary mathematical

models of the rheological  properties of concrete, long-time losses of prestressing and the long-time effect of concrete and  prestressing reinforcement.

The long-time monitoring of the structure will thus be an essential contribution to the development of the theory and technology of building of bridges and also for

the future designs of bridge structures of this type.

The siphon variant of a swirl turbine for the utilization of the energy of water flowing over weirs is based on the fact that the turbine has no guider. It comprises only an impeller, a shaft and a generator. The turbine is of the self-service type. The hydraulic section is designed to enable the machine at the moment of start to operate at a synchronous operating speed as a pump. This causes  flooding of the siphon with water and the machine is automatically transferred into the generator, i.e. turbine rigime.   The machine can be stopped very easily – again fully automatically by means of an air-inlet valve located at the highest point of the transfer elbow. Because the siphon arrangement does not require a turbine room, the building expenses are minimum. This concept can exploit the energy of water flowing over a weir with minimum financial investment. Owing to the operating conditions - hydraulic efficiency up to 86% and a greater through-flow  - swirl turbines are fit for use on rivers already from a surface slope of 1 m.

The project of a small run-of-the-river hydraulic power station with a siphon-based swirl turbine was implemented in the Želina locality. This was the world premiere of the concept of a low-cost swirl turbine for run-of-the river hydroelectric power stations. The power station was put into operation on July 1, 2016.

  A System of Road Traffic Constructions of the Prague City Ring Road in the Myslbekova St. – Pelc Tyrolka Section

 

to a team from METROSTAV, J.S.C.

led by

 Ing. Miloslav Hadrava, FEng.

 

 

By presenting the award the EACR appreciated the realization of a system of road constructions – The Blanka Tunnel Complex – designed to releave a significant part of the capital from heavy traffic. The Blanka Tunnel Complex is an extensive technical and organizationally complicated structural system. It required cooperation of many teams from various investors and suppliers and teams of project engineers. The implementation was exceptionally complex also due to the fact that traffic restraints in Prague had to be minimized. The team from METROSTAV finished the the construction successfully. The advanced technologies used in the costruction took full account of the complex geological conditions. From a technical viewpoint the Blanka Tunnel Complex is by one generation ahead of tunnela previously built in Prague. The system of traffic constrol in the tunnel compex guarantees high safety and fluency of traffic and the ventilation system is expceptionally environmentally friendly. The project showed the ability of Czech project engineers and suppliers to build such a masterpiece which which was monitored with great interest even from abroad.

Award for 2014

 The award for 2014 was presented in the category for an outstanfing project to a team of designers from VÚTS (Research Institute of Textile Machines) J.S.C. , Liberec, headed by Ing. Petr Jiráček, Ph.D.

 

Cam grinding machine BRV-300 CNC

 

By presenting this award the EACR appreciated the advanced concept of this machine tool which unites technological processes of precision milling, measurement and subsequent grinding and quenching of cams. A 3-axis control system was developed for this mechine. The exceptionality of the system of the cam grinding machine, the concept of which was developed at VÚTS is based on the fact that another way how to control the motion of production axes is to use two interconnected electronic cams. The system also processes the values of eccentricity of placing of the cam on the rotational axis C and transforms it into the coordinate system of the machine. The values of the output driving registers are generated in a PLC user defined function. The outline of the cam is measured without having to remove the cam from the machine and the measured values are used to correct production data generated by the user defined function. Precision milling and measurement of the shape without removing the machined part from the machine tool simplifies production and makes it possible to achieve higher accuracy of milling and hence reduction of the grinding allowance.

Award for 2013
The award for 2013 was presented in the category for an outstanding project to a team of designers of steel structures of open pit mining equipment from NOEN, J.S.C.Uničov, headed by Ing. Jan Marek, CSc. "Steel Structure of Bucket Wheel Excavator KK 1300".
 
By presenting this award the EACR appreciated the statical, dynamic, form and strength optimization of the design of a new, type K1300 bucket wheel excavator. In contrast to an older, type K2000, equally powerful excavator, the weight of the new type was reduced by 11% and the production costs also by 11%, which represent a total cost reduction of CZK 158 mio.
The KK1300 is the first bucket wheel excavator dynamically tuned from the beginning of its development  in a way ensuring that the operating frequencies of the bucket crowding including further harmonic frequencies exhibit the highest possible rigidity when the bucket is engaged in the cut. In addition the KK1300 excavator is equipped with a specially tunmed and damped operator´s cabin suspension and a switch room which protect the operator and the expensive electrical equipment from vibrations. After a two-year pilot operation at the Doly Bílina mining company, the function of the KK1300 excavator was rated excellent. It is expected that in the nearest future this type of excavator could be a good export commodity of Czech engineering industry.
