The invention relates to hydraulic construction and can be used as shore protection structures in erodible channels of rivers, canals and other structures.

A device for mounting slopes of river channels or channels gabion [1] , consisting of a metal mesh shell and filler in the form of active metallurgical slag. The disadvantage of this technical solution are:

the shape of the frame of the gabion is variable and can be deformed during operation and lead to the destruction of attachment in General;

- mount over time may break down due to mechanical sufoziya, removal of fine particles Foundation through the pores of the gabion, so as not provided protivokorrozionnoe protection;

- durability of fastening, consisting of such spaces is small due to the destruction of fastening due to corrosion and abrasion mesh in direct contact with the sediment without the protective layer.


the design is quite a complex technical solution that makes it not reliable and expensive cost;

- mounting in direct contact with the fluid flow and transported sediments and therefore may be subject to rapid wear and destruction in a short time, it is especially dangerous to use this mount on debris flows;

- efficacy of mounting is greatly reduced when in the river or the canal have ysenia the efficiency and reliability of coastal protection riverbeds and channels from erosion and durability lifetime of shore protection structures.

This objective is achieved in that on the prepared base bottom and slopes, cross-sections of the riverbed or channel tightly laid a layer of stones, the dimensions of which are approximately equal. The densely lined with a layer of stones, square or rectangular in plan for the device structural joints laid a layer of high-strength mortar or concrete that is aligned with the height and tightly fills the space formed between the stones. On the layer of high-strength mortar is placed in the mesh roll, which in the extended form deepens and prisypaetsja top of another small layer of high-strength mortar or concrete in such a way as not to fill the previously formed structural expansion joints. The cell size of the mesh does not exceed the size of the stones of the underlying layer and thus improves the adhesion of stones and mesh. The mesh netting and a layer of mortar or concrete tightly fits the second layer of stones that are larger than the dimensions of the underlying layer. Laying stones when this is carried out in such a way that as they dig down to increase the efficiency of coupling layers between them.

This design armoutbearer credit is nymi blocks with four sides by mesh netting. Armorycalifornia mount works on bending load so that tensile forces are taken up by mesh netting, and compression works or top of the rubble concrete, or lower part, depending on the direction of action of the active load. If the active load is directed downward, the stretched area is the lower layer, if the up - top. Structural expansion joints filled solid or recorded during operation armoutbearer fastening. Designated break armoutbearer fastening filled with concrete. High dynamic and static loads, the number of layers of stones and grids can be more respectively two and one and depends on the magnitude and direction of action of these loads.

Mesh concrete design gives more flexibility than conventional valves, as opposed to the armature it has painotalo shape and tensile structures, in which it is located, tends to return to its original position. The reinforcement mesh netting is especially effective when the action of the load, which is the vibrational-vibrational in nature and is constantly changing in module and direction. PR is s, as mesh netting under tension in one direction is compressed in the transverse and accordingly compresses the concrete in the transverse direction, it is well known that the load-carrying capacity of concrete in compression is ten times more than in tension.

Armorycalifornia mount can be made in the plan in the form of immutable armoutbearer frame, broken by the length of the structural expansion joints and cells rectangular or square shape. At the bottom of the cells arranged protivokorrozionnoe device in the form of the inverse filter, which prevents the removal of small soil particles that are deposited on the bottom of the channel or riverbed, and this causes deformation of the cross section. On protivokorrozionnoe device in the cell is tightly stacked stones of large size or stones, having a greater mass. To prevent possible deformation from the effects of water flow, as well as to enhance the rigidity of the cells and structures armoutbearer mounting generally diagonally in the plane of the placement of the mesh corners of the cells are connected by stretch marks and make them immutable triangular shape in plan.

In Fig.1 shows a cross-section of the riverbed or channel arkabutla butobetonnymi mount bed and banks with three layers of stones; in Fig.3 - armorycalifornia fastening channel of the river or canal, a top view; Fig.4 - node a in Fig.1; Fig.5 - node In Fig.2; Fig.6 is a cross section of riverbed or channel frame form of accommodation embotelladora mounting; Fig.7 is a top view of the riverbed or channel frame form of accommodation embotelladora mounting; Fig. 8 - section C-C in Fig.7 in the version with two layers of stones; Fig.9 - section C-C in Fig.7 in the version with three layers of stones.

The channel cross-section 1 consists of a bottom 2 and slopes of 3, which is arranged armorycalifornia fastening, consisting of aromatology 4 blocks, which are divided in terms of structural expansion joints 5 into squares or rectangles. Place the knuckle mounting filled with concrete 6. Armorycalifornia mount consists of layers of stones 7, between which is placed the valve in the form of mesh netting 8 in the concrete layer 9. Structural expansion joints 5 are filled with bulk material 10. In the case of frame shape armoutbearer mounting in the cell 11 is provided protivostoyanie device 12, which is tightly stacked stones 13. Cell 11 having a rectangular or square shape in plan, diagonally in the plane of tubetone mount is assembled and operates as follows. On the prepared bottom 2 and the slopes of the 3 cross-section of the channel 1 is tightly laid a layer of stones 7, the dimensions of which are approximately equal. The densely lined with a layer of stones 7 squares or rectangles for the device structurally-joints 5 is laid a layer of high-strength solution 9, which is aligned in height. On the layer of high-strength solution 9 is placed mesh roll 8, which in the extended form deepens and prisypaetsja top of another small layer of high-strength solution of 9 thus, in order not to fill the previously formed structural expansion joints 5. The cell size of the grid netting 8 does not exceed the size of the stones 7 underlying layer and thus improves the adhesion of stones 7 and the mesh 8. The couplings 8 and coat tightly fits the second stone layer 7, the dimensions of which are larger than the underlying layer.

This design armoutbearer mounting has increased flexibility due to the presence of structural joints 5 and the connection between armorycalifornia blocks with four sides by mesh netting 8. Armorycalifornia mount works on bending load so that tensile forces are taken up by mesh netting 8, and on the Noi load.

Structural expansion joints 5 are filled with bulk material 10 or recorded during operation armoutbearer fastening. Designated break armoutbearer fastening filled with concrete 6. High dynamic and static loads, the number of layers of stones 7 and meshes Rabitz 8 may be greater than, respectively, two and one and depends on the magnitude and direction of action of these loads. Mesh netting 8 concreted design gives greater flexibility than conventional valves, as opposed to the armature it has painotalo shape and tensile structures, in which it is located, tends to return to its original position. Tensile armoutbearer block of 4 with mesh netting 8 greatly increases the carrying capacity of its tensile strength, so as mesh netting 8 under tension in one direction is compressed in the transverse and accordingly compresses the concrete in the transverse direction, it is well known that the load-carrying capacity of concrete in compression is ten times more than in tension.

Armorycalifornia mount can be made in the plan in the form of immutable armoutbearer frame, broken by the length of the structural expansion joints 5 and with cells 11 Prao filter, which prevents the removal of small soil particles that are deposited on the bottom 2 channel or riverbed, and this causes deformation of the cross-section of the channel 1. On protivokorrozionnoe device 12 in cell 11 tightly stacked stones 13.

To prevent possible deformations, as well as to enhance the rigidity of the cells 11 and designs armoutbearer mounting generally diagonally in the plane of the placement of the mesh 8 corners are connected by braces 14 and attach to the cells 11 immutable triangular shape in plan.

The proposed solution has a number of advantages over other previously known. The proposed technical solution can be used in local construction material, which is the most cheap and affordable. Design flexibility is a great advantage of this construction as it is in the water and to avoid possible deformation of the bottom and the base is impossible, but it will cause a distortion of the structure, which is not dangerous for this type of mounting. Gabion destroyed easily installed in the operating process.

The reinforcement mesh netting is especially effective when the action of the load, which are vibratio the prioritization of known similar solution is cheaper due to economies of concrete, as well as reliable protection from abrasion mesh during operation. While durability of these structures more than previously known similar technical solutions.

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.
