(57) Abstract:

The method and apparatus is intended to strengthen the earthen structures erected or built on a weak Foundation, including swampy. The method includes drilling using a casing of wells along the structure by cutting through his body, the underlying layer of peat and depth in the mineral bottom. Then in wells consistently lower working electrode, which is connected to the electro-installation, fill the wells hardening material and produce electrical discharges in the lower part of the well and rise to the formation along the rows of wells impervious walls of the formed closely adjacent to each other or split piles. Device for strengthening includes a movable platform, consisting of four connected by a flexible connection sections, and supports in the form of two rows of tubes along the buildings in the drilled wells. Tube most remote from the longitudinal axis of the construction of some form supporting elements, supports, and pipe another some form of casing elements to work on strengthening. At first during the section hosted platform drilling rig, IRS - rotary valve for extracting tubes from wells. The invention provides a reduction in labor and materialsfrom, reducing turnaround time and improving the quality of strengthening and durability of the structure. 2 S. p. f-crystals, 5 Il.

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.

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.
