Slide Gate


► Function

These equipments are probably the most widely known for the regulation of open canals and distribution systems. They can be adapted to different width and height dimensions. In addition, they can work with large water levels (bottom intakes) or on the surface. Sealing can be one-way or bi-directional, through continuous rubber seals.


According to the hydraulic loads to which they are exposed and other operating conditions, flat gates can be of the sliding type (with sliding skids) or the wagon type (with wheels on a roller track).


  • They allow sectioning the water flow in the canal or in lateral reservoirs to the canal.
  • They allow simple level regulation according to the upstream and downstream levels of the flow section.​


► Application

  1. Intake works on rivers.
  2. Bypass structures in irrigation canals and intake structures in reservoirs or lateral dams.
  3. Bottom outflows of dams or reservoirs.


► Features and Tips for use

Inspired by a simple hydraulic conception, they are totally robust and devoid of any mechanical complication, which allows them to adapt to the most severe working conditions. They can be automated.

Features

  • Robust manufacturing.
  • Wide choice of lifting systems applicable (direct, gear and screw, toothed rack reducer, oil hydraulic cylinder, galle chain, etc.).
  • Allows manual or automated operation (remote control).
  • Operational guarantee in severe weather conditions.
  • High sealing performance.
  • No solids are retained at the bottom of the canal.
  • Low and simple maintenance.

Tips about use

  • According to the type of installation, they can be of the "in-wall", "wall-mounted" or "framed wall-mounted" type.
  • Civil works of standby, with a certain quality level, are normally required.
  • ​ Automatic Siphons can be mounted on the same structure, offering both a bottom discharge for cleaning and a safety element for upper intake in a single unit.

Tilting Weir (Overshot) Gate


► Function

This equipment can be installed in canals or rivers. They allow maintaining a minimum level upstream, whatever the flow rate. As the flow increases, they drop until they completely fold back, allowing the flow to circulate without overflowing upstream.


  • They guarantee a minimum upstream level for lateral bypasses or river intakes.
  • They allow water to be stored in the riverbed itself for irrigation, landscaping or as a sports reservoir.


► Application

  1. Intakes in rivers, with "mobile weirs" in natural watercourses.
  2. Control of discharge levels for measuring in irrigation canals.
  3. Maximum level control in head chambers of hydroelectric power plants.
  4. Mobile weir in dams.
  5. On demand flow control in a canal, operating in association with a measuring structure.
  6. Landscaping creating calm water areas of tourist and/or sporting interest.


► Features and Tips for use

Inspired by a simple hydraulic conception, they are totally robust and devoid of any mechanical complication, which allows them to adapt to the most severe working conditions. They can be automated.

Features

  • Precise and robust mechanisms.
  • Do not require electrical energy to be dropped.
  • Flood safety device.
  • Elevates the water level without retention of floating material.
  • Small variations in level translate into large variations in throughflow.
  • Large widths can be covered without intermediate piers.
  • For mobile weirs.
  • Low and simple maintenance.
  • Fish ladders can be mounted.

Tips about use

  • Mechanical actuation is available for smaller dimensions and oil-hydraulic for medium to large dimensions.
  • The height of the equipment can be reduced by placing it on a permanent weir or a slide or radial type gate, offering flexibility to the installation.
  • May leak minimally.
  • It is suggested that protective fencing be installed to minimize possible vandalism to the actuators.

Distributors


► Function

This equipment can be installed in canals or reservoir outlets. They can supply a practically constant flow rate, independent of upstream level fluctuations (within certain limits indicated in the corresponding diagrams).


  • They guarantee a constant flow rate for free water discharge.
  • ON/OFF opening.
  • Manual operation (can be automated on demand).


► Application

  1. Canal bypasses for equitable flow distribution.
  2. Oulet Control in reservoirs with little level variation (avoids excessive water consumption).
  3. Outlet control in reservoirs with high level variation (associated to other TEMEC equipment).


► Features and Tips for use

Inspired by a simple hydraulic conception, they are totally robust and devoid of any mechanical complication, which allows them to adapt to the most severe working conditions. They can be automated.
