FIELD: construction.
SUBSTANCE: invention relates to construction and can be used in erection of cluster pads (engineering preparation) for drilling rigs during development of oil and gas deposits in complex engineering and geological conditions. Method for erection of subgrade of cluster pad for drilling rig, in which reinforcing layers are formed layer by layer in form of cages from geosynthetic materials, for this purpose, a web of geosynthetic material of each layer is laid, ground is poured on it and compacted, after which free edges of the material are brought over the ground and fixed. Each reinforcing layer is arranged with two packs of cages located on both sides of the line of direction of movement of the drilling rig and at a distance determined in accordance with design features of the drilling rig. Material with breaking strength of 100–1,000 kN/m is used as material of cages.
EFFECT: reduction of uneven settlement in transverse direction, provision of subgrade with high operational stability.
