Description

The invention relates to hydraulic engineering, in particular to flood control measures.
There is a method of protecting territories from flooding in river basins by accumulating floods in temporary reservoirs that form using dam dams, while dam dams are placed on the tributaries of the river, along which floods are expected to arrive, and they are placed sequentially one after another, each of which are made in the form of a stone filtering embankment with a self-regulating spillway, and the body of the stone filtering embankment is placed in a steep canyon of the river and formed by an explosion (RF patent No. 2389845 C2, priority date 01/10/2006, ata publication 20.05.2010, the authors Apollonov YE, KOLOSOV MA et al.).
The disadvantages of this method are the high labor costs and increased danger of the method of forming a stone filtering embankment by the explosion of the body, as well as the susceptibility of the dam dam to active mudding, due to which the pass deteriorates and overflow becomes possible.
A known method of dealing with flooding from floods, adopted as a prototype, according to which a collapsible structure is assembled along the river bank from spacer elements consisting of a metal-plastic pipe with concrete aggregate inside, while spacer elements are assembled into a triangular prism by fixing them with clamps around the transverse reinforcement with the formation of nodes, on the pressure side, a waterproof fabric with waterproofing is laid on the spacer elements, and a drainage ditch with a pump for collection and removal of filtered water (RF №2312949 C1 patent priority date of 19.06.2006, publication date 20.12.2007, author Lamerdonov ZG, prototype).
The disadvantage of the prototype is the low efficiency of both the construction method and the constructed flood control structure, due to the following reasons:
- firstly, the design features of a collapsible structure, made throughout in the form of a single structure of one unchanged prism, which leads to the need to erect the entire structure before the flood begins, does not allow for a rational installation of the prism taking into account the terrain, as well as to ensure effective impervious protection;
- secondly, using metal-plastic pipes filled with concrete, which, as you know, practically does not work in tension, which leads to the need to use composite, high-strength and expensive materials of metal-plastic pipes, which bear all the loads;
- thirdly, the insufficiently reliable flexible design of the waterproofing of the pressure head;
- fourthly, the lack of an effective anti-filtration device when installing the structure on the dam, which inevitably leads to leakage, and in case of damage to the waterproof fabric, to the destruction of the structure.
In addition, the prototype method is time-consuming and costly, since the reliability of the structure being constructed is ensured by the implementation of the lower tiers of more massive spacers, and the reliability of the connecting node of the spacer element is ensured by the reinforcement installed in it only after concrete has gained strength in the pipe, the standard duration of which is 28 days.
The objective of the invention is to increase the efficiency of the flood protection method by ensuring safe flood costs through soil structures, while ensuring the integrity of the flood protection structure, reducing labor costs during its construction and the possibility of using it on terrains with difficult terrain.
To solve the problem in a flood protection method, including the construction of bank protection structures in low-pressure and flood-prone sections or on water-resistant soil structures in the form of a collapsible pressure structure against an overflow flow with the waterproof protective devices secured from the side of the inclined pressure section and with the possibility of dismantling according to at the end of the flood, according to the invention, a collapsible pressure structure with support units of modular type is erected and, at the same time, the modules are assembled in the form of rod tetrahedra of a quick-detachable design according to the scheme of a three-hinged arch or according to the scheme of a welded or collapsible arch, the modules are installed at a distance from each other or next to the topography and the shape of the outlines of the pressure structure and fix them either in the ground with supporting elements, or on a foundation laid on a waterproofing layer, an array is installed in the modules that provides resistance to hydrostatic pressure, and the modules are interconnected with Strongly sheets and / or rods which are secured in modules nodes via connecting elements, and on the pressure side is set waterproofing protective means forming a waterproof protection in a pressure zone with rigid and / or flexible design of the upstream side.
According to the invention, waterproof slabs of the pressure zone or blank precast panels are used as waterproofing protective means, with which they form a rigid construction of the pressure face.
According to the invention, waterproof protection in the pressure zone is carried out using a complex of waterproofing protective equipment.
According to the invention, a reinforcing mesh is fixed to the pressure structure, marks with soil are laid on it, covered with a waterproof roll coating that is fixed to the structure, and a flexible structure of the pressure face is formed.
According to the invention, the waterproof protection is made in the form of an external ceiling of a waterproof material and a shield.
According to the invention, before installing a collapsible nanor structure on a water-bearing soil structure, waterproofing preparation of the base of the structure is carried out, while waterproof soil is laid and compacted, on which prefabricated tape foundation elements are laid for mounting a pressure structure on them.
According to the invention, factory-ready modules can be used in the method.
Figure 1 shows the General scheme of flood overflow of water in low areas; figure 2 shows a cross section aa along the lowering section of figure 1; figure 3 schematically shows a collapsible pressure structure of a modular type in plan; figure 4 shows various structural solutions for the assembly of modules and support elements; figure 5 - options for the implementation of waterproof protection: a) the design of hard protection using waterproof plates or panels, b) the design of flexible protection using a set of waterproofing protective equipment, and c) using waterproof fabric; figure 6 shows a diagram of the use of a protective structure against the overflow of water through an earth dam.
According to the claimed method of flood protection, the construction of shore protection structures is carried out in areas that are lowered and prone to flooding, including with a complex terrain having a curvilinear configuration (Fig. 1), as well as on water-resistant soil structures (Fig. 6). The protective structure is erected in the form of a collapsible pressure head structure 1 of a modular type with support nodes and with an inclined pressure face (Fig. 1, Fig. 2, Fig. 3). Modules 2 are assembled in the form of rod tetrahedra of a quick-detachable structure according to the scheme of a three-hinged arch, which allows you to assemble the structure quickly and taking into account the terrain (Fig. 4). It is also possible to perform a modular design according to the scheme of a welded or collapsible arch. In this case, prefabricated modules can be used to reduce labor costs during installation. Modules 2 in the form of rod tetrahedra are installed on the ground at a distance from each other or next to taking into account the features of the relief, the shape of the outline of the pressure structure, and also taking into account the orientation when forming the inclined pressure face. Depending on the state of the soil, the modules are fixed with, for example, abutment teeth 3 directly in the soil or on the foundation, which is used as prefabricated tape foundation elements 4, laid on compacted waterproof soil, such as clay (figure 4). To ensure stability against hydrostatic pressure, an array 5 is additionally placed or pre-installed in the modules, for example, a concrete block. The tetrahedron shaped modules installed in this way are reliable support nodes of the erected protective anti-flood design, which are interconnected to form an inclined pressure face. To do this, use connecting rods 6 and shields 7, which are fixed in the nodes of the modules using known connecting elements, for example bolted connections (not shown conditionally). On the pressure side, on the edge of the rod tetrahedra or on the rods forming the ribs 8, waterproofing protective devices are installed and waterproof protection is created in the pressure zone with a rigid or flexible design of the pressure face (Fig. 5).
In this case, the rigid structure of the pressure face is formed by fastening waterproof plates or blind precast panels 7 (Fig. 5a).
Alternatively, a reinforcing mesh is fixed to the pressure structure, marks with soil 9 are laid on it, covered with a waterproof roll coating that is fixed to the structure, and thereby form a flexible combined construction of the pressure face (Fig. 5b).
Alternatively, a flexible design of the pressure face is created by tensioning the waterproof fabric sheath K) directly on the structure rods or shields (Fig. 5c).
Installation of a collapsible pressure head structure on a water-bearing soil structure 11 is carried out from the reinforced pressure side. At the same time, there is no need to complete the construction of the soil structure and labor costs for its strengthening are reduced. To ensure waterproofing protection of the water-bearing soil structure before the installation of the structure, waterproofing preparation of the base of the structure is carried out and prefabricated foundation elements 4 are used. In this case, waterproof soil 12, in particular clay, is laid and compacted, prefabricated tape foundation elements 4 are laid and the pressure structure is mounted on them (Fig. .6).
Thus, the claimed method creates an effective barrier in the form of a collapsible design of a modular type with reliable support nodes operating in shear, which can be dismantled at the end of interference.
The inventive method of flood protection has several advantages due to the structural features of the built-in protective collapsible structure of a modular type, and is more effective than the known methods, as it provides less labor-intensive construction on an area with a complex relief of the flood protection structure, which has a high antifiltration and structural reliability, while characterized by mobility, the ability to assemble in place from th element with all the features of the terrain and can be dismantled after leveling, the ability to prevent flooding lowered portions and overflows through the water retaining ground structures while maintaining the integrity of the protective structure with substantial savings in material costs.
