Definitions

  • the invention relates to hydraulic engineering and can be used predominantly in hydro-technical dust structures with a large width of the passage opening, e.g. are used in protective dikes that are built near large port cities to protect them from flooding.
  • hydro-technical dam structure with a passage opening, a closure of the passage opening, which consists of at least one flap, which has a bluff body, which is connected to the base of the weir with the aid of a horizontal axis and is pivotably mounted about the said horizontal axis, a niche for accommodation the flap, which is carried out in the weir sole on the underwater side and a means for lifting and lowering the flap is known (US-A-3756032).
  • a disadvantage of this hydrotechnical structure is its low operational reliability, which is connected with the fact that during operation of the hydrotechnical structure, precoat deposits collect which prevent the flap from swinging away from the passage opening into the niche. If the flap is incompletely pivoted into the niche, the depth of the passage opening is reduced and this is inadmissible because damage to the hull can occur when a ship passes through the passage opening.
  • a hydrotechnical dust structure (US-A-4103497), in which, in contrast to the one described above, a means for removing precoat from the niche is provided.
  • This means is designed as a pipe that runs inside the bluff body.
  • the pipeline has an upper end that is open to the upper water side and a lower end that ends in the niche. If the bluff body is in the upper, ie in the operating position and there is a water level gradient between the upper and lower water, a water flow flows under the dynamic pressure via the pipe from the upper water into the niche and moves alluvial deposits.
  • This hydrotechnical structure has an insufficient effectiveness in washing away alluvial deposits, which reduces the operational reliability of the structure.
  • the insufficient effectiveness in flushing away the precoat is due to the fact that the said water flow is unable to remove precoat from the entire surface of the niche due to its great length, which reaches 15 to 20 m, and due to energy scatter into the surrounding medium.
  • the invention has for its object to provide a hydrotechnical dust structure in which the means for removing precoat from the niche is designed so that the effectiveness in removing these precoat and thus the operational reliability of the hydrotechnical dust structure can be increased.
  • This task is connected in a hydrotechnical accumulation structure with a passage opening, a closure of the passage opening, which on the width of the passage opening consists of at least one flap which contains a bluff body, by means of a horizontally arranged axis with the weir sole and can be pivoted about said horizontally arranged axis attached, a niche for accommodating the flap, which is carried out in the weir sole, a means for lifting and lowering the flap and a means for removing precoat from the niche according to the invention in that a trench is made in the base of the niche, which is covered by the bluff body when it is in the niche and, together with the lower wall of this bluff body, forms a channel which is closed on the circumference, the hydrotechnical structure having a pump for removing precoat from the said channel and said channel and said channel Pump together form said means for removing precoat from the niche.
  • the base of the niche is inclined towards the trench.
  • longitudinal dividing walls are set up in the trench, with the aid of which the said trench is divided into individual sections which are open on the bluff body side and the base area of the bluff body when it is in the niche located, interacts with these longitudinal dividing walls via sealing elements which are made of an elastic material.
  • This design allows alluvial deposits to be removed alternately from individual sections which, when the bluff body is located in the niche, represent circumferentially closed channels with a relatively small cross-section, which increases the effectiveness of removing alluvial deposits and pumps with a lower output can be used .
  • the hydrotechnical dam structure contains a protective weir 1 (FIG. 1) with a passage opening 2 and a closure of the passage opening 2, which consists of several flaps 3 which are arranged on the width of the passage opening 2.
  • the closure can also consist of a flap 3.
  • Each flap 3 contains a hollow bluff body 4 (Fig.2), which is connected to a weir sole 5 by means of a horizontally arranged axis 6 and has an opening 7 in its lower part, by means of which the inner cavity of this bluff body 4 with the surrounding one Medium is connected.
  • a niche 8 is designed to accommodate the flap 3 in the niche 8.
  • An inclined trench 9 is implemented in the recess 8.
  • the trench 9 can also be carried out without inclination.
  • a base 10 of the recess 8 is inclined towards the trench 9.
  • the angle of inclination of the base surface 10 can be determined in experiments without difficulty in such a way that precoats from the niche 8 roll optimally into the trench 9.
  • the bluff body 4, when it is located in the niche 8, is supported against the base 10 of this niche by its base 11 via the sealing elements 12 which are made of it and which are made of water-resistant rubber, for example.
  • the trench 9 forms together with the bottom 11 a channel closed on the circumference.
  • a pump 13 for supplying water to the trench 9 is arranged on one head of the protective weir 1 (FIG.
  • a means for lifting and lowering the flap is provided in the hydrotechnical structure, which means a (not shown) Compressed air source, which is connected via a pipeline 15 (FIG. 2) to the inner cavity of the bluff body 4 and includes a valve (not shown) for venting air from said inner cavity.
  • the trench 9 is divided by the longitudinal dividing walls 16 into individual sections 17, which are open on the side of the bluff body 4.
  • Each section 17 can either have its separate pumps 13 and 14 or be connected to these pumps, which are common to all sections, via a manifold (not shown).
  • the bluff body with the weir sole can not directly, but in another way, e.g. be connected via an intermediate frame.
  • the hydro-technical dam works as follows.
  • the passage opening 2 is sealed off (FIG. 2), ie when the bluff body is in the raised position and the recess 8 is open, the alluvial deposits entering the recess 8 roll over the inclined base surface 10 into the trench 9 and collect therein .
  • the bluff body 4 is pivoted about the axis 6 and housed in niche 8. Since there are practically no precoatings on the base 10 of the recess 8, the bluff body 4 is completely inserted into the recess 8 and the passage opening 2 is fully opened.
  • the mud pump 14 sucks precoat from the trench 9 and the pump 13 supplies the trench 9 with pressurized water from its other side, as a result of which the trench 9 is effectively cleaned.
  • the sealing elements 12 form a seal of the channel formed by the trench together with the bottom 11 of the bluff body 4 and thereby also contribute to the more effective cleaning of the trench 9.
