The present invention relates to the field of hydraulic construction, in particular to the field of protection of submerged crossings of the erosion of the bottom layer of sweats on their construction and laying carry on the shore with the help of crane equipment and the underwater part manually using divers (Alperin I. E., Bykov, L. S., Gurevich Century, the Strengthening of the banks of navigable canals, rivers and reservoirs. - M., "Transport", 1973, 216 S.; Ivanov, I. A. improving the technology of construction of channels and fastening them gabions in the area of deep soil freezing. Hydraulic engineering and land reclamation construction. Prof. thesis., - M., 2000).

However, the complexity, high cost and low level of mechanization of work produced does not allow a wide use of gabions, despite their obvious advantages.

Closest to the proposed design is developed in France specialized unit for underwater laying of geotextile in order to protect the bottom of the river from erosion (application FR No. 2734291, IPC 7 E 02 At 3/12, 1998), including pontoon boats, dryer stacked mesh tape, tank rock ballast output holes.

But the known device cannot provide the Assembly and placement of gabion structures in the water flow, especially in the area of the passage underwater pressure pipelines.

The objective is to increase the degree of mechanization and quality of the construction and placement of gabions in the water flow.

The decision is floating drum for stacked mesh tape, tank rock ballast output holes, according to the invention equipped with a roller conveyor for gabion tape consisting width of several baskets of cells over which sequentially placed bunker for rock ballast and dryer mesh belt, and the area of the roller conveyor to the hopper is made horizontal, and then with a gradient of 5-7and the outlet of the hopper is equipped with hydraulically controlled valves, and the number of output holes corresponds to the number of baskets of cells along the width of the gabion tape.

Several sections of roller conveyor after the drum can be performed live.

In Fig.1 shows the installation of the underwater laying of gabions, side view; Fig.2 - the same, top view; Fig.3 - depicts gabion tape, composed of a wire mesh ribbon.

Installation for underwater laying gabion includes pontoon boats 1, the roller conveyor 2, a hopper 3 having in the bottom a few outlets with hydraulically controlled valves, the drum 4 for mesh tape. Section 10 of the roller conveyor 2 is a horizontal section 11 - UKL the crossings from the degradation of using the proposed setup is as follows.

Gabion structure is a mesh boxes-cells collected from the wire mesh in the form of gabion tape filled with rock ballast.

The wire is delivered to the craft 1, mounted on the horizontal section 10 of the roller conveyor 2 and manually collect gabion tape 8, consisting in width from a few boxes of cells, for example three. On the pontoon boat has a 9 excavator, equipped with grab bucket. With the help of craft 1 download rock ballast, which then fill the hopper 3. The hopper 3 is mounted above the roller conveyor 2 and has at the bottom a few outlets, equipped with a hydraulically controlled valves. The number of output holes corresponds to the number of baskets of cells along the width of the gabion tape. With open flaps of rock ballast from the hopper 3 is filled in the boxes-cell gabion tape, which under the action of its own weight moves along the inclined portion 11 of the roller conveyor 2. Bias in 5-7enough for smooth movement gabion structures on the roller conveyor 2 under the action of its own weight. For hopper 3 on the conveyor 2 has a drum 4 with the nao on top. End ready gabion structures connected with ropes 6 onshore winch 7. Then gabion structures on the inclined area of the roller conveyor 2 is immersed in water. For more quick and smooth immersion several sections of roller conveyor 2 may be driven.

To place laying on the bottom of the water flow gabion construction tighten using ropes 6 winches 7 installed on the shore. Precision styling is achieved with the help of special sites set on a course of movement of the vessel.

We offer installation for underwater laying of the gabion can increase the level of mechanization and quality of work that allows greater use of gabion structures in hydraulic engineering.

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.
