Description

The invention relates to the field of construction and can be used to strengthen and arrange the foundations and foundations of buildings and structures.

A known method of creating a soil-reinforced structure [1].

A device of a soil-reinforced structure is known, which is a structure in whose body additional hollow shells are laid, and their cavities are filled with a working medium under pressure during construction and operation with the possibility of being arranged along, across and locally in a checkerboard pattern [1].

The reason that prevents obtaining the desired result is to create the front wall of the shell, which complicates the design.

Known micropile, which contains an injection pipe, at the lower end it is fixed to an expanding shell of easily deformable and waterproof material with a strength that ensures its integrity when pumping concrete or water-cement slurry, and holes are made in the expanding shell to more fully fill it with concrete mix [2] .

The reason that prevents obtaining the desired result is the local impact on the soil mass.

There is a method of creating a geotube, the erection of which occurs through a pipe-hose supplying a water-ground mixture, and a pipe is mounted from the opposite end of the shell connected to a pipeline that removes clarified water. Filling is fixed by monometers [3].

This method does not meet the technical solution, because unable to maintain the design position of the soil mass during the operational period.

The proposed soil-reinforced base contains a system of longitudinal fillable shells 1 of composite materials, presumably nanomaterials with memory, and transverse multi-shell elements 2 also of composite materials with memory, for example, nanomaterials, special anchor elements 3, corrugated flexible connections 4, bulk (technogenic) or natural soil mass 5, injection pipe 6, controlled gate valves 7, valves 8 connecting shells with gate valves, measurement sensors are stressed o-deformed state (VAT) of the soil mass 9, the control panel 10, the end part of the shell 11 with holes 12, which ensure clarified water to enter the drainage well 13, followed by pumping to the treatment plant 14, thereby strengthening the foundation (foundation) of the structure 15 ( see figure 1, 2).

The method of erecting a soil-reinforced base (foundation) is as follows: shell 1 of a composite material having a memory (nanomaterial) is introduced (laid) into a technogenic or natural massif in the longitudinal direction, then transverse multi-shell elements 2 of composite material are mounted on them, and they can have inside one or several shells possessing a memory of various composite materials (nanomaterials). After this, the soil mass 5 is filled in and the next rows are repeated or they are introduced into the natural mass using special devices (for example, a guided head of television and radio equipment) through the prepared well.

After this, soil is filled and the next layer of transverse elements 2 and longitudinal filled shells is laid, and the valve of the end part of the longitudinal 1 and transverse 2 shells is connected to the injection pipe 6 with a valve 7. Filler is fed into the longitudinal 1 and transverse multi-shell elements 2 through the injection pipe 6 moreover, special anchor elements 3 of the longitudinal shells 1 are also filled, additionally ensuring the reliability of the system, clarified water is supplied through the end part of the shells 11 and holes 12 in renazhnuyu system followed by pumping it into a sewage treatment plant 14, with subsequent use for technical purposes. If during operation the soil mass or shell systems 1 and 2 are deformed, then they change their parameters according to the memory of the composite material and restore the design position of the base due to load reformation and use special flexible connections 4 that make it possible to change the position of shells 1 and 2, ensure the safety of the base of the structure 15 as a whole.
