Co 1 The invention relates to land reclamation and can be used in cleaning silt from drainage. There is a known method of cleaning the drainage from sedimentation of local drainage areas at the site where the sedimentation site opens the drainage line, extracts the silted drainage tubes, cleans and then re-places it in the trench, which is filled in by D3. The disadvantage of this method is the large amount of earthworks for opening and re-filling the drainage line. There is also known a method of cleaning the drainage from silting by washing, which includes the supply of washing water into the drain cavity through its source 2. A disadvantage of the known method is the high washing cost. The aim of the invention is to reduce the cost of wash water and shorten the cleaning time. This goal is achieved by the fact that a tampon made of a water-permeable, water-soluble material with a density lower than the density of water is inserted into the cavity of the flushed drain. Moreover, ice is used as a material for making a tampon. The drawing shows a drainage line at the place of silting erosion, a longitudinal section. The drainage area 1 is clogged with sediments of sludge 2. The living cross-section of the stream at the erosion site overlaps the tampon 3, made of ice. The jets 4 of the washing water 5 are throttled at the point of contact of the sediments of the sludge 2 and the tampon and intensively erode the sediments of the sludge 2. As the sediments are washed out, the tampon 3 moves along the eroded part of the sediments. The proposed method is implemented as follows. A tampon made of a waterproof material that is soluble in washing water and with a density lower than the density of washing water is introduced into the cavity of the drain 1. The material of the tampon 3 must be waterproof, since otherwise water will be filtered through it and it will not be possible to narrow the living cross-section of the stream at the site of sludge 2. 532 inside the drain of the washing water 5 to the place of erosion of silt 2. In the place of Archimedean force presses the tampon 3 to the upper part of the inner surface of the drain 1. Due to this, the washing water 5 rushes to the place of contact of the silt 2 and tampon 3 deposits. are powerful jet-4-washing water 5, which erode the sludge intensively furred mouth 2. If drains 1 goes into the closed collector, then after washout of sludge deposits tampon 2 3 passes into the manifold, dissolves and does not clog the drain. The tampon 3 is given a torpedo shape with a length of at least 1.5 and no more than three diameters of the drainage pipe. With a length of less than 1.5 times the diameter of the drainage pipe, the tampon dissolves until the sludge has eroded. With a length of more than three diameters, material and labor costs for its manufacture significantly increase without a noticeable increase in washing intensity. The diameter of the tampon 3 should not be less than 0.8 and not more than 0.9 diameter of the drainage pipe. Reducing the diameter of the tampon to less than 0.8. The diameter of the drainage pipe reduces the intensity of the erosion of the deposits, since the tampon does not provide a sufficient narrowing of the living section at the place of erosion of the deposits. Increasing the tampon diameter greater than 0.9 of the diameter of the drainage tube makes it difficult for it to move along the drainage line when the drainage pipes are displaced and reduces the drainage cleaning efficiency. Tampon 3 can be rationally performed with ice from the wash water. The polyethylene film is made into a mold, filled with wash water and frozen in a refrigeration unit. Under field conditions, household automobile refrigerators can be used. The ice pack is freed of polyethylene film and drains are introduced into the cavity. Then water is fed into it. Water is supplied by means of a flexible hose by gravity from a trough irrigator passing along the sources of drains. The flow of wash water 5 moves the tampon 3 to the place of deposition of sludge 2. There 3. 11411534
