Description

 The method for constructing dumps relates to methods for carrying out work in hydraulic engineering, in particular, to methods for constructing landfills for disposing of production and consumption wastes during oil and gas production.

 There is a method of constructing a landfill, which consists in its construction on the territory where clay and heavy loam are located at the base (see UDC 502.3 (470) Protasov V. F. Ecology, health and environmental protection in Russia. - M.: Finance and statistics 1999, p. 430).

 However, this method has significant disadvantages.

 For the construction of the landfill, it is necessary to find a new land plot, which entails certain costs for finding an appropriate place for the subsequent allotment of the land plot and for the construction of a landfill for the disposal of production and consumption waste on it. In addition, lands that could be used for agricultural purposes are alienated. This method of constructing landfills is unacceptable for the wetlands of Western Siberia, where there are no clay and heavy loam in the underlying upper horizons.

 Closest to the proposed one is the method of creating alluvial artificial foundations (see UDC 622,692.23.072 Kolomeytsev VT Construction of foundations for cluster drilling in Western Siberia. Overview. Ser. "Oilfield construction". - M .: VNIIOENG, 1981, 17-18) with the subsequent construction of landfills on them in accordance with SNiP 2.01.28-29 "Landfills for the disposal and burial of toxic industrial waste."

 However, this method has a significant drawback, namely, for its implementation, it is necessary to carry out the removal of a new land plot, to wash or fill the soil of the base from mineral soil, and then build a landfill. In other words, the implementation of this method requires a relatively high cost.

 The aim of the invention is the efficient use of land resources, reducing costs for the construction of landfills for the disposal of waste harmful effects on the environment.

 This goal is achieved by the fact that the disposal of production and consumption waste is carried out on the site between the external and internal debris, which is built around the provisions of abandoned wells.

 The drawing shows a diagram of the implementation of the technical solution.

 The scheme consists of entrance 1 to the well pad 2 with external bunding 3, the positions of abandoned wells 4, around which an internal bunding 5 has been constructed.

 The method is implemented as follows.

 For the landfill, a well pad 2 is selected, on which there are abandoned wells 4. The internal debris 5 is constructed from mineral soil. Depending on the distance between the positions of the abandoned wells 4, the internal debris 5 is made around each position of the abandoned wells 4 or one internal delineation 5 around all positions of the abandoned wells 4. Waste is delivered to cluster pad 2 through entry 1 and placed on the cluster pad 2 between inner 5 and external bunding 3. The pad 2, if necessary, is divided into parts, each of which is filled with waste separately.

 The beneficial effect of this technical solution consists in the rational use of suitable land for its intended purpose and previously allocated land to the nature user, reducing the cost of constructing landfills for disposal from waste, and harmful effects on the environment.
