MITRE GATE IN RIVER PORT PRAHA LIBEŇ
(2005)

Mitre gate is installed in a mouth 12 m wide and it is 10,75 m high. The gate weights about 41,5 t. Both gates are equipped by linear mechanical drive made in „Strojírny Kukleny“ with max. power 150 kN. A groove is welded to the circumference of the gate to allow for placing a rubber seal. In the right part of the gate there is a little sluice gate controlled by linear mechanical drive TMP 71 - MSS Moldava. The lower bearing is equipped by the tube for supplying lubricant. The upper bearing is self-lubricating and is a standard SKF bearing and case for fitting on a wall ironing. In every gate niche there are six screw stops guaranteeing the position of the gates in the correct position.



SLUICE GATE FOR WATER POWER PLANT PŘELOUČ
(2003)

This two sluice gates is non-typical structure because of its size and difficult assembly in outlet channels. Gates are horizontally split and its location is fixed by pull-out pins. In the lower part of the gate is placed the inflow valve gate manually handling from the foot bridge of the drive mechanism. Both gates are partially balanced by concrete counter-weight. The seal made by standard lip rubber is placed on the all circumference of gates. Gates are hanging on the Gall's chains and on the upper position are equipped by arrest. The size of gates are 6x5,5 and 6x8 m.

The gate is produced and placed as one assembly piece composed of the gate body itself seated on two bearings in side shields, a strutting transverse threshold and side frames with aeration piping and cable bushing mounted and with antifreeze finish areas. The driving mechanism is located on the left-hand side pier, anchored partly on the side shield, partly in the pier concrete structure; it is connected with the gate via a pin bar.
This type is a protected industrial model.



WEIR GATE FOR RECONSTRUCTION OF A WEIR ON DŘEVNICE RIVER
(2001 & 2005)

A tilting gate weir of 22 m width is composed from two partial eleven-meter long tilting gates mounted on three ball bearings where the central bearing is common for the both parts. Each gate is formed by a bearing tube in the weir tilting axis and by a damming sheet with transverse braces. The tilting gate weir is unilaterally controlled from a machine room located in the pier side wall shaft. The movement within 90° scope is ensured by a hydraulic cylinder. The side shields are from stainless steel and they are provided with de-aerating piping. The damming height is 1,2m.

TILTING GATES FOR UPSTREAM NOSE OF GABČÍKOVO LOCK CHAMBERS
(1995)

The four closing gates serve for a quick temporary closing of the upstream nose, reducing of flow through the two lock chambers and for emergency operation of the lock chambers at the head gates failure. The tilting gates have active damming height of 5 m, however, they are designed to enable overflow of a water jet of 0.5 m height even at erect position of the damming structure. In one lock chamber of 34 m width there are two gates of 17 m width each while every one of them is anchored on four bearings. Each tilting gate has an independent drive by two double-action direct-line hydraulic motors and it is equipped with a mechanical locking.



GABČÍKOVO WATER DAM
(1999)

Rope-operated cleaning machine with a grab suspended on a rotating crane arm. The grab serves for removal of big objects which cannot be taken by the rope-suspended shovel. The collected waste is assembled in a mobile container. The working cycle is in steps and the machine travels on a dam crest, the whole process is controlled from a control room. The machine control may be switched over between automatic and manual ones. The cleaned depth of inlet is approx. 30 m.

KADAŇ SMALL HYDRO-ELECTRIC POWER PLANT
(1997)

A static two-arm cleaning machine equipped with a tilting shovel of 7,2 m width with a scraper bar. The arms movement is ensured by a sequential hydraulic mechanism with direct-movement hydraulic motors. The collected waste is loaded into two transport containers which are shifted out with a movable platform to the bridge deck.



PIVOT BRIDGE ACROSS THE LOCK VNOROVY II.
(1999)

This type of a pivot bridge of 100° movement scope has the deck width of 3,5 m and its total length is 15,6 m. The bridge is dimensioned for a normal loading capacity of 22 t and an exceptional loading capacity of at least 40 t. The bridge foundations and abutments are solved in such a way not to interfere with the lock chamber structures and not to influence them even by a static action. The bridge body itself is formed by a steel structure, concrete counter-weight and additional steel weight from sheets. A total period of the bridge switch-over between the both extreme positions is approx. 3,3 minutes.

PIVOT BRIDGE ACROSS THE LOCK UHERSKÝ OSTROH
(2002)

The pivot bridge with 100° movement scope has the deck width of 3,5 m and its total length is 15,6 m. The bridge is dimensioned for a normal loading capacity of 22 t and an exceptional loading capacity of at least 40 t. The bridge foundations and abutments are solved in such a way not to interfere with the lock chamber structures and not to influence them even by a static action. The bridge body itself is formed by a steel structure, concrete counter-weight and additional steel weight from sheets. A total period of the bridge switch-over between the both extreme positions is approx. 3,3 minutes.



THE FLOOD PROTECTION OF PALACE ŽOFÍN IN PRAGUE
(2005)

The stainless steal membrane flood wall protection which is 125 m length and 2 m high is the new flood protection solutions for standalone buildings. Easy and quick assembly and small storage space highly reduce costs of purchase, assembly and storage. This mobile flood wall protection is consists of vertical zinc coating pillars putting in the concrete base and stainless membranes which are connected with pillars by special locks. The minimal storage space allow to storage directly on the place of use.

RECONSTRUCTION OF RIVER BANK IN VESELI NAD MORAVOU
(2003)

The solution of reconstruction river banks in Veseli nad Moravou was created with more respect for historical monuments zone. For reconstruction was used well-tried bank protection which increase flood protection of over bank land by more aesthetic way.



PORT STAND IN PROTECTION RIVER PORT PRAGUE – SMICHOV
(2004)

Port stand consists of five pile clusters with axial length 30 m which are connected by floating moles with width 3 m. Between this moles and river bang there is the space for leisure and sporting boats with area of apx. 20 x 120 m. The stands is connected with river bank by movable foot bridge and by fixed foot bridge with the head of embankment where is situated the water and electrical connection point. On the bank are situated three headlight for lighting of both foot bridges.

DIRECT-FLOW TURBINES
(1998)

Turbine VC 1220 is of a direct-flow propeller type, controllable blades of an impeller. Turbine casing completes an hydraulic shape of a simple concrete channel in which water flow speed raises progressively. Turbine has its own hydraulic set intented for controlling. Control range is ± 10°, speed of blade adjustment 1°in 2 seconds.



PUMPING RAFT
(2003)

This pumping raft(with a pumping output of 350 l/s at max. delivery of 10 m) has the advantage of low weight, small dimensions (respecting road clearance limits) and the possibility of connecting canvas, metal or plastic hoses of DN 250 mm as auxiliary delivery piping. The water-pumping set is made up of two separated units located on two frames. If there is a fault on one of the units of water-pumping set the second can be used whilst carrying out repairs without leading to excessive tilting of the raft. The tube filters rotate and therefore easy to clean and can be quick dismantled using the special screw mechanism.
