Description

The invention relates to the field of construction and can be used in the construction of retaining walls and bases on artificial embankments or soils with low bearing capacity, shore protection structures.

A shore protection structure is known that contains buns located normal to the shoreline and placed between them a wave extinguishing element made in the form of a wave energy suppression chamber having a pressure wall with slotted openings, a wave extinguishing roller placed under the pressure wall, wave extinguishing filters installed in the chamber, an accumulation well, made at the base of the chamber, and an artificial sandy beach adjacent to the inner wall of the chamber. The method of its construction is as follows: perform a quenching chamber with a wave extinguishing roller under its pressure wall and an accumulation well at the base; accumulate nano-forming soil material and wave extinguishing filters are grown in the accumulation well. The grown wave-damping filters build up the external slopes of the buns (RF patent No. 2097483 “Shore protection structure and the method of its construction.” Specialized research and production association “Baltberezashchita”).

This structure is applicable only to large water bodies, and the disadvantage is the complexity of the work on its construction.

Reinforcing tapes are woven into the enclosing surface made of interwoven flexible tapes, and the free ends are provided with additional load-bearing capacity by joining them in pairs, forming flexible loops. The disadvantage of this method is the complexity in the production of works and material consumption in its implementation.

A device of reinforced structures from flexible tapes is known (RF patent No. 2181407 with the priority of the invention “Method for creating soil-reinforced structures from flexible tapes and a device for its implementation.” Kasharina TP, Kasharin DV), which is a enclosing surface made of intertwined flexible tapes, the free ends of which give additional bearing capacity due to the connection in pairs, while forming flexible loops.

A device is known for retaining structures (AS No. 647391 with a priority of 04.25.1977 “Retaining structure.” V.N. Burdinsky, Yu.M. Kosichenko, B.I. Sergeev, TP Kasharin), consisting of blocks divided into two parts, front and anchor, which are formed by a zigzag panel.

The disadvantage of these devices is the complexity of the work, energy consumption, material consumption.

The present invention solves the problem of using soils with low bearing capacity as the foundations of buildings and structures.

This technical result is achieved by creating a soil-reinforced retaining structure consisting of a flat front wall made of a single panel of composite materials with a memory (nanomaterials) and attached to it by flexible connections of reinforcing elements in the form of horizontal armor shells and inclined armor bands, at the end of which an additional drainage shell is arranged, filled with a sorbent and connected to a drainage system that discharges contaminated runoff, and the lower and upper parts of the facial wall The threads are made in the form of anchor blocks, and a storm drain device is attached to the upper block.

Distinctive features of a soil-reinforced retaining structure are the presence of a front wall ending with an anchor block in its lower and upper parts, rectilinear armored shells and inclined, horizontal flat or corrugated armored ribbons straight or inclined with an additional sheath-draene, flexible ties, and they are threaded through the front wall flexible connection, ensuring its stability.

The proposed soil-reinforced retaining structure is illustrated in figures 1 and 2.

Figure 1 shows a soil-reinforced retaining structure. Figure 2 presents the sections.

A soil-reinforced retaining structure is a structure consisting of a front wall made of a single panel of composite materials having a memory (nanomaterials) 1, bulk soil 2, attached to it by flexible ties 3, reinforcing straight-line tape-shells 4 and inclined flat or corrugated armored tape 5 ending in a shell-drains 6, having special openings 7 and filled with a sorbent, connecting their entire series along horizontal or vertical planes connected to the drainage system 8, which discharges contaminated water, and the upper and lower parts of the front wall are made in the form of anchor blocks 9, while the storm drain device 10 is attached to the upper anchor block (Figs. 1 and 2).

The operation of the device reinforced retaining structure is as follows. After the construction device is installed, the front wall perceives external and internal (from bulk soil) loads and their distribution is performed according to the stress-strain state of the entire soil-reinforced massif, i.e. tensile stresses are perceived by reinforcing rectilinear sheathing tapes and inclined flat or corrugated tapes ending with a draene sheath collecting filtered water that is discharged through the drainage system, and the front (enclosing) wall in the upper and lower parts is reinforced with anchor blocks, and to the upper a storm drain device is attached. The material of the front wall and anchor tapes is made of nanomaterials with memory and restoring ability, allowing you to save the design position of the soil-reinforced structure in operation, ensuring the reliability and safety of the entire technical system.

During operation, in case of violation of the stress-strain array of the tape-sheath 4, inclined flat or corrugated armored tapes 5 bear the entire load and hold the front (enclosing) wall 1 of composite materials with memory (nanomaterials) in the design position, and the tape- the shells 4 are filled as necessary, increasing their volume and bearing capacity, filling the voids formed, and the corrugated armored tapes 5 increase their length, preserving the design positions of the structure, appearing schiysya drain polluted water is discharged through drain shell 6 into the drainage system, ensuring the reliability of the array as a whole.

The construction of a soil-reinforced structure is as follows (Fig.1 and 2).

First, a single faceplate panel 1 is laid on the prepared base from a composite material having a memory (nanomaterial) and secured with an anchor block 9. Then, soil 2 is filled, moistened, compacted, a movable formwork is installed to maintain a single faceplate panel 1 in the design position, then the tape-sheaths 4, inclined flat or corrugated armored tapes 5, are threaded into the front wall 1 and are laid according to the selected parameters: first inclined 5, horizontal and if corrugated 4 from composite materials with memory, then a drain shell 6 is placed, filled with sorbents with special openings 7, which allow the penetration of polluting waters and their purification with sorbents connected to the drainage system. Then, straight-line armored shells 4 are laid out, which are filled as necessary. After backfilling, the process is repeated again. In the upper part, the front wall 1 is fixed with an anchor block 9 connected to a stormwater discharge device 10. Armored shells 4 are filled as the structure deforms and sags, maintaining the design position of the entire soil-reinforced retaining structure, ensuring its safety as the foundation of buildings and structures on low soils bearing capacity, including municipal solid waste landfills or storage facilities, roads and railways, shore protection, etc.
