Abstract

Use: in hydraulic engineering construction, in particular in engineering structures on rivers to protect coastal areas from eroding coastal floods. SUMMARY OF THE INVENTION: A flood protection structure includes hollow blocks mounted on a foundation. Inside the blocks, plates are installed in their cavities with the possibility of vertical movement. As the water level rises, the plates are displaced along the upward guides, thereby protecting the coastal areas from erosion. 3 hp f-ly, 4 silt

Description

The invention relates to hydraulic construction, in particular to engineering structures on rivers to protect coastal areas from erosion and flooding of the coastal strip.

The purpose of the invention is to increase the reliability of coast protection from flooding.

Fig about 1 shows the construction, side view; On. FIG. 2 - the same, top view; Fig 3 is a section A-A in Fig 0 1; on big.4 - section BB in Fig „1„. . ...

The flood protection structure contains coastal sloping clothing made in Lorma sectional ducts 1, superimposed by plates 2 with the ability to move within sections 3 along profiled guides 4, made both inside sectional ducts 1 at a given distance from each other, and beyond clothing in height H, corresponding to the calculated horizon of tornado effects. Profiled guides 4 at the top

its parts 5 are fixed to the counterforts of frame triangular configuration 6, resting with their lower beam 7 on the upper natural planned base of the slope 8, the lower zone of the sectional ducts 1 is made with holes 9 for water flow, in turn the shaped guides 4 are made in their middle parts of the section in the form of a square 10 or a circle, of which, at a variant of the square 10, free vertices 11 are located along the axis. symmetry of the width of the box 1, and the upper part 5 of the guides 4 above the box 2. and made an I-beam configuration 12 with their implementation in the cross section of the middle part also in the form of squares 10 or a circle. The guides of the triangular configuration 14 along the normal to the water flow, containing trapezoidal section beams 15 facing the narrowed edges 16 inside the frame 14 h, are rigidly fixed to the guides of the 4 sectional ducts 1 on the ground 13 side. The lateral edges 17 of the plates 2 are made

in accordance with the broken edges 18v 2, the specified guides 4 are obtained. Furthermore, between the spaces between the concrete tooth, the concrete tooth 19 and the lower edge 20 19 and the lower edge 20 of the plates 2 in the plates 2 in the duct sections 1 are 5 sections 3 on the lower parts of the duct, there is a space 21 with its 1 fixed for the purpose of ensuring the provision of forces by the limit stops 22 of the plates 2 stroke.

Protective structure against floods Profiled guides 4 works as follows. Provide rigidity of boxes 1 and

When raising the level of low tide waters, JQ are thus elements for water flow up to the level of flood water, the attachment to them of the buttresses 6 and 14 penetrate through the openings 9 in the spaced and dividing walls between sections 21, limited in height 3

a ton tooth, 19 and the bottom face 20 When the flood waters of the slab 2 of the slabs 2 and exerting pressure is shifted along the guides 5 from the top to the bottom of the lower face 20, lifts the plates of its part 5 to the lower position 2 upwards in the section along the direction of the yu occupies the space of the links 3 of the boxing 4, both inside the sectional ducts 1 with the plates supported by 2 lower edges 1, and in height H up to the calculated 20 on the stops 22 of the stroke. Clamping up the water level. At the same time, the provision of beams 7 in the ground 13 ensures that when this flow is effected, the pressure of the frames 6 ”is applied to the plates 2, which are displaced to the upper

zone 5 of guides 4, this Formula of Invention is transmitted by pressure on guides 4, which keep this pressure due to closure 25 1 o Protective structure from the triangular buttresses triggered to them, mounted on the foundation and configuration 6, taking into account the support including hollow blocks with open-bottom beams 7 counterforts 6 on the fuses for entering water, made the upper base otkazennymi in their lower parts, and with the release of 8 and their pinch. Moreover, the implementation of 30 spaced in their cavities with the possibility of guides 4 in the upper part of vertical movement of protective 5 I-beams 12 configuration is not elements, at the same time. In the lower part it only increases their rigidity, but the block also has limiters to reassure the density of elements - plates 2 to guides 4 taking into account the length of 35 S ee so that, in order to increase the middle part in the cross section of Nepni, the protection of the coast from the squares 4 or 10 in the Form of flooding, is provided with at stan- ding of the circle, preventing the foam and foam from falling in the same plane along the outflow medium beyond the limits of the protective sediment by the lower and upper buttresses of the weapon 040 TRAUGOLN Forms in the cross section of the frame frame. made from the front, rear triangular configuration 14 from the side and horizontal beams, with the top of the ground 13 being normal to the water buttresses installed on the natural flow, to the guides 4 in the zone of the coronately planned upper base of the bars 1 provide reliable Work E5 slope and lower mounted in the slope, sloping clothing, taking into account in addition, the protective elements of the existing forces of passive resistance, are not in the ID of the plates, the internal cavities held by the box 1 due to the profiled units are equipped with profiled the triangular surface equalized for slabs, the blocks are supported on frames 14, namely, by means of trapezoidal-50, the front beams of the lower buttresses, 15 beams facing the front beams of the upper buttresses, also with burned edges 16 inside the frame 14. by the profiled guides of the same, the execution of the lateral boundaries of the 17 slave plates, and the lateral faces of the slabs have the contours 2, in accordance with the broken edges, the shape of the profiled guides of the 18 guides 4 ensures reliable 55 a sliding articulation.2 The construction according to claim 1, which is tl and is due to the fact that the profiled limiters 22 guides in the cross section in the zone of the lower ridges of the 20 plates are square. eight Fig F IG 3 fip4
