Description

The invention relates to the field of hydraulic engineering construction and can be used in the installation of retaining and regulatory structures (retaining-metrological, retaining-aeration) on a soil-filled foundation, for supplying water to consumers, during the construction of coastal protection structures, as well as a flood protection structure in various emergency situations.

The known design of the supporting-regulatory structure of double-acting and the method of its construction (RU, RF Patent No. 2246583, C2 E02B 7/02, BI No. 30 from 10.27.2006). The double-acting supporting and control structure includes a flexible flatbet reinforced on the base, an upper supporting and regulating wall with a retaining front plate, flexible side flaps, a vertical wall that provides damping energy of the iridescent flow, flexible tooth-abutment, rigid and flexible connections, lower supporting and regulating a wall with a corresponding retaining front plate. A flexible flatbet is reinforced on the basis of soil-filled anchors with which it is connected by flexible connections. A flexible tooth-firm rigid bond is attached to a flexible flatbet in its center.

The disadvantage of the above design in the base part is that, with significant hydrodynamic influences, the front plate, which supports the base, loses its design position and moves together with the base in the direction of flow, while dangerous filtering processes begin to develop between the bottom and the flexible flute, which can lead to loss of stability.

The known design of the retaining and aeration regulatory structure and the method of its construction (RU, RF Patent No. 2141552, E02B 7/02, BI No. 3 of 11/20/1999). During the construction of the retaining and aeration regulatory structure, a flexible flatbet consisting of a flexible ponur and a flexible apron is assembled. At the beginning of the flexible ponur, a flexible tooth with a fastening is arranged, which is placed in a pre-prepared trench and rammed. When mounting structural elements to a rigid mount, placed on a flexible ponder, a central spillway, side vents, a holding plate and an aerator are mounted.

The disadvantage of this design in the base part is the low operational reliability of the structure, since when a flexible tooth with an attachment or flexible anchorages fails, the entire structure will gradually lose stability.

The closest technical solution is the design of the retaining and regulatory structure on a ground filled flute bet and the method for its implementation (RU, RF Patent No. 2009125513, E02B 7/02, BI No. 1 of 01/10/2011), including a water-tight casing with water outlet upper and lower windows, fixed in the upper part due to the anchor supports, and in the lower part - on the soil-filled flash bet made of soil-filled shells interconnected by flexible connections, and the channel anchors are made of soil-filled or other multi-shell elements ov.

The disadvantage of the design in terms of the base is its complexity, which requires a certain amount of time for its installation and installation.

The essence of the invention is the creation of the base retaining and regulatory structures with a high degree of reliability, ease of operation and the ability to quickly erect.

The technical result is an uninterrupted supply of water to water consumers due to the durability and operational safety of the base of the supporting and regulatory structure.

The technical result is achieved due to the construction of the base of the retaining and regulatory structure, which consists of multilayer shells connected to the base by internal flexible flexible bonds, which are tapes of heavy-duty material, fixed inside the shells along the entire length, i.e. one tape connects two shells.

The base of the retaining and regulatory structure is used mainly on inter-farm land reclamation canals and small waterways with a width of up to 10.0 m and a depth of 1 to 5.0 m.

Multilayer fillable shells with internal flexible flexible connections are made to order at the enterprise (Russia, Rostov Region, Aksai, Promyshlennaya St., 1a) from Unisol fabric (http://www.texclub.ru), manufactured according to TU V .2.7.-21.1-34989706-001: 2007 "Cellulose fiber material" Unisol "(" Unisol "), 0.41 ÷ 0.78 mm thick.

Multilayer shells are a container for aggregate (for example, in our case, dry sifted sand) with a length of 1.0 to 2.0 meters and a diameter of 0.25 ÷ 0.5 m, and flexible flexible ties are a tape elastic heavy-duty material (for example "Kevlar-Polyamide" according to TU 1319-001-27480011-01 "Carbon clusters are highly ordered. Technical conditions") with a thickness of 0.1 ÷ 0.15 m and a length equal to the length of the multilayer shell. The length and diameter of the multilayer shells are selected depending on the characteristics of the channel. For greater stability, filled shells adjacent to the coastal slopes (extreme) make a larger diameter (1.5–2.0 times more than the main shells laid along the bottom of the watercourse). The free ends of the flexible flexible bonds connecting the multilayer shells are made approximately (± 5 cm) long, equal to the radius of the shells, and serve to create additional elasticity and stability under load during their deformation, creating an additional emphasis.

Multilayer casings with flexible flexible connections are mounted at the factory, and a metal-polymer cable (according to TU 1259-002-25435667-2005 "Metal-polymer cable. Technical conditions") is soldered inside the shell, which comes out of the shells in the form of mounting loops for ease of movement and installation in the mainstream. The outlets of the metal-polymer cable are additionally waterproofed with building silicone (for example, Weicon Silicone according to DIN 50021/53167 Corrodibility class). Mounting loops are arranged at a distance of 1/4 from the ends of the shell. At the end of the shells, a 0.1 m long gap is made to fill the filler near the installation site.

A container of multilayer shells is transported assembled by road to the installation site of the retaining and regulatory structure.

The construction of the base of the retaining regulatory structure is carried out in the following sequence.

The channel of the reservoir is prepared, cleaned of large debris and clay preparation is made with a thickness of 10-15 cm. The preparation is carried out by an excavator of the type EO-4112 A “Dragline” hitch with a perforated bucket.

The filling with the filler of the multilayer shells is carried out in the following sequence: a technological pit with a slope is arranged (for the convenience of fixing, filling and sealing of filled shells), into which empty multilayer shells are fed from one side, filled manually with a filler through a VT-10 technological funnel (with a short length base) or by means of mechanization (for example, sand pump PB 100 / 31.5 or its modifications) - with a large length of the base. The slots into which the filler is filled are sealed with a manual ultrasonic welding machine for gluing the K-100 film (www.piaterka.ru/images/oborud-vesy/cas/CAS_ruk/CK-100.pdf). The design, as it is filled, is moved beyond the mounting loops by vehicles.

The finished base of the retaining and regulating structure is installed into the channel using mechanical means - hoists, for example, hoisting systems of the type ST-135-25 (with a watercourse width of up to 5 m), or they are attached via slings to a crane (for example, KS-45-71 7 K-1 “Ivanovets”, boom length 9.21 m, boom reach 2.0–20.0 m, load capacity 25 t, wheeled chassis) on the opposite bank of the installation site, and when the boom is retracted, the base is set into the prepared channel by dragging ( with a watercourse width of 5 to 10 m).

The base of the retaining and regulatory structure maintains a stable position due to its own weight, gravity of the water and adhesion to the prepared bottom.

For fastening the membrane-cable-stayed dam on the basis of the retaining-regulatory structure, two screw-in anchors are additionally provided in the channel (for example, steel grade 3 according to GOST 24379.1-80 “Foundation bolts (anchor)”).

The proposed base retaining and regulatory structures is illustrated by the drawings in figures 1-5. Figure 1 presents a diagram of the base of the retaining regulatory structure (top view). Figure 2 presents a diagram of the base of the retaining regulatory structure (side view). Figure 3 shows the node A. In figure 4, the layout of the mounting loops. Figure 5 shows the position under load of the free ends of elastic flexible ties.

The base of the retaining and regulatory structure is made of multilayer filled shells 1 (Figs. 1-5), extreme multilayer shells of larger diameter 2, interconnected by elastic flexible connections 3 (Fig. 3). To move the structure, mounting loops 4 are provided (Fig. 4), which are the exposed, free parts of the metal-polymer cable 5 soldered inside along the multilayer sheath. The filler is sand 6, its filling is done through slots 7. The places for the metal-polymer cable to go out 8 are waterproofed.

The base of the retaining regulatory structure works as follows: when installing on the base of the supporting regulatory structure, the base of the retaining regulatory structure is deformed, i.e. a change in the stress-strain state, while the multilayer filled shell 1, the outer multilayer shell of a larger diameter 2 and elastic flexible bonds 3 change their position. Depending on the efforts arising in the process of work, the base acquires stability and elasticity due to the bending of flexible flexible bonds 3 and tension of metal-polymer cables inside the shells 5, providing a high level of reliability and safety.
