(57) Abstract:

The invention is intended to strengthen earthworks, constructed or erected on a weak Foundation, including swampy. The method involves drilling along the construction of wells using casing. For each path are drilling at least three rows of wells with the upper surface of the earthen structures with cutting through his body and the peat layer and the depth in the underlying layer of peat mineral bottom of 1.0 - 1.5 m wells consistently lower working electrode, which is connected to the electro-installation, fill well-curing electrically conductive material and produce at the level of the bottom of the well a specified number of electrical discharges. Then raise the casing with the electrode up to the top of the well and not removing the electrode, made up of solid electrically conductive material and re-produce electric discharges at the level of the top of the wells. This form combines the piles of each row of gratings, on top of which is placed a layer of substrate material. The method provides a reduction in labor and materialsfrom, improving the durability of reinforced construction and quality strengthening the relates to the field of construction, including transport, road and hydraulic engineering and can be used to reinforce earthen structures for various purposes, including embankment subgrade, dams, earthworks, intended for the construction of various structures, etc. of the objects erected on the weak, including marshy grounds.

There is a method of strengthening earthworks, including mines by drilling from the surface slant wells and installing them in tether anchors with downhole locks, and wells are spirally along the axis of the glide plane, with a depth of penetration of the diameter of the helix is reduced (see SU inventor's certificate, 1717725, CL E 02 D 17/20, 1992).

FIELD: building, particularly hydraulic structure reinforcement.

SUBSTANCE: method is performed in two-stages. The first stage involves forming vertical elongated flat ground massifs secured by hardening material. Massifs are created in crest embankment area and in upper area of embankment slope so that massifs are spaced minimal available distance from crest and pass through embankment body, including land-sliding upper embankment slope area. Massifs are anchored in mineral bottom by lower edges thereof and are arranged at least in three rows and there are at least three massifs in each row. Method for massifs forming involves driving double-slotted injectors directly in embankment ground or in wells formed in embankment and having plugged wellhead; orienting injector slots perpendicular to hydraulic pressure head vector direction in embankment area to be reinforced; injecting hardening material under increased pressure across horizons from top to bottom or in reverse direction, wherein injection is initially performed under 5-15 atm pressure and at minimal rate in each second injector of one outermost row beginning from extreme ones; feeding hardening material in previously missed injectors in this row; supplying injectors of another extreme row with hardening material in the same way; feeding hardening material to ejectors of medium rows under 10-20 atm pressure; performing the second reinforcement stage as material hardens to obtain 70% strength. The second reinforcement stage involves forming vertical elongated flat massifs of secured ground anchored in mineral bottom by lower edges thereof and arranged at least in three rows, wherein each one includes at least three massifs. Massifs extend at the angle exceeding embankment slope angle to horizontal line. Massifs are formed with the use of double-slotted injectors in remainder embankment area. Injector slots are directed perpendicular to hydraulic pressure head vector direction in embankment area to be reinforced. Hardening material is ejected in above succession, wherein hardening material pressure is equal to design process pressure enough for direction of feeding hardening material through injector slots and lesser than hardening material injection pressure of the first reinforcement stage.

EFFECT: increased reliability of structure reinforcement; prevention of land-slide on structure slopes.

SUBSTANCE: method involves compacting ground of embankment body and cones; forming drainage layers and water-draining chutes on coating; creating pad with variable rigidity decreasing in direction from bridge along embankment for length equal to approach slab length; arranging approach slab having upward gradient in bridge direction. Pad of embankment body is formed by creating cast-in-place piles along with surface compaction of upper cast-in-place pile parts and upper embankment layer, wherein transversal cast-in-place piles form strips having medium rigidity jointly with ground forming embankments. The medium rigidity is reduced from maximal value at bridge pier to minimal one at approach slab end opposite to bridge pier.

EFFECT: reduced embankment subsidence under approach slab due to decreased pad and draining material displacement in horizontal direction.

FIELD: manufacture of plant covers used for beautification of streets, squares, construction of sportive grounds, as well as for landscape designing.

SUBSTANCE: method involves spraying organic adhesive onto fine-mesh basalt net by means of specially designed equipment for filling meshes to thereby create strong carrier base. Net is perfectly ecologically safe and allows seeds to be uniformly sown over the entire area of lawn. Adhesive used for providing lawn is functioning as nutritive compound for seeds and is used simultaneously for protecting seeds from external influence of moisture and air during prolonged periods. After drying in first drying chamber, mixture of lawn grass seeds is sown onto carrier base through dosing hopper, followed by applying onto given mixture of organic adhesive and drying in second drying chamber. After discharge from drying chamber, ready dry lawn is cut into parts of various lengths, wound into roll and hermetically packed in polyethylene film for further storage and transportation. Lawn is placed on site by unwinding roll onto preliminarily prepared ground and spilling nutrient mixture thereon, followed by heavy irrigation to provide for sprouts emergence. Nutrient mixture and lawn grass seed mixture compositions are worked out depending on climatic zone and composition of parent ground on which lawn is to be provided.

EFFECT: increased efficiency by providing uniform sowing of seeds over the entire lawn area, and damage-free transportation and handling of grown lawn.
