Abstract

The invention relates to soil reclamation. The purpose of the invention is to reduce the pollution of drainage waters. Drainage systems are laid on the drainage and humidification system and connected to the collector. Then in the direction of 60-90 ° to the drains deep loosening is carried out with constant depth. The depth of loosening choose 15-20 cm less than the depth of laying drains. Simultaneously with deep loosening, the treatment of loosened soil is carried out by a chemical meliorant, and the thickness of the soil-soil layer is regulated, reducing it to the place of laying the drain. The water in the loosened layer enters the drain, and its main flow comes from the soil that has not been treated with chemical meliorative, which prevents contamination of the drainage water.

The invention relates to soil amelioration 1 can be used in the construction of drainage and wetting systems and is an improvement: a technical solution according to author. No. 1 tU733.

The aim of the invention is to reduce the cost of construction and pollution of drainage water.

The method of soil reclamation is carried out in the following way. ; Drainage systems are laid on the drainage system and connected to the collector. Then, in the direction of 60-90 to the drains, deep loosening is carried out with a constant (downstream) depth. The depth of loosening is selected by 15–20 cm less than the depth of the flap of the drains. Simultaneously with deep IMM loosening, the treatment of the loosened soil is carried out by a chemical meliorator, 11 (the thickness of the treated layer is p | eguliruet, reducing to the place of mortgaging). The interdiscipline, which coincides with the position of the depression curve in the drainage mode.

To implement the method, it is advisable to use the following loosening unit: on a crawler track (type T-130) a cistern with a compressor (type RUP-8) is mounted, the rear part of which is equipped with a dispenser with a supply pipe. When loosening is carried out, the ripper is buried and the chemical meliorant is supplied by the compressor through the pipe. The supply of the compressor is periodically changed, decreasing to drains, which provides the variable TOL1TSIN soil treatment with chemical meliorant "

The water in the loosened layer enters the drain, and the main stream of water comes from the soil that has not been treated with chemical ameliorative, which prevents contamination of the drainage water. There is practically no water flow along the lower part of the loosened soil and the undiluted soil, their drying occurs mainly as a result of drying. Since part of the soil has been treated with a chemical meliorant, this prevents its rapid compaction by the running gear of the machines, the upper part of the loosened soil is slightly compressed, since it is rarely in overmoistened condition and subjected to the structured action of drains

In the humidifying regime, water is supplied to the drains, as a result of which a level of water rises up near them, which through the loosened soil enters the middle part of the interdiscipline. Since the sole of the loosened layer does not have bulges in the middle of the interdiscipline, this provides an intensive outflow of water from the drain, which is also facilitated by the fact that the most permeable soil treated with chemical meliorants is located in the middle of the interdisc, where the pressure gradient is minimal, but the movement of the water continues.
