RU181463U1 - Frame protection wall over the crest of existing dams for flood protection - Google Patents

Abstract

The main direction of the proposed utility model is the installation of a protective wall along the crest of existing earth dams to increase the volume of the watercourse in the event of an emergency caused by flooding. The frame of the protective wall is made of asbestos-cement pipes with a diameter of 100 mm. Racks 4.0 m long are installed in wells with a diameter of 150-200 mm and a depth of 1.0 m. Fastening by transverse and longitudinal beams is carried out by steel plates from a standard channel on bolted joints. Cladding with galvanized profiled sheets is carried out on overlays attached to the posts from a C-shaped galvanized profile with an overlap device for one butt wave. The joint is filled with a fiberglass pad impregnated with epoxy resin. The total height of the protective wall is 3.0 m. On the upper beams, a running floor is 1.0 m wide with a cable fence. The construction of the frame and cladding is carried out without the use of lifting equipment by a limited number of performers.

Description

Frame construction made of asbestos-cement pipes, lined with galvanized profiled sheets, performed along the crest of existing fence dams in emergency situations caused by flooding.

The prior art:

An analogue of the proposed utility model is the methods of building up existing dams in order to increase the throughput of rivers and canals in emergency situations:

- filling an additional ridge over existing soil (sand) with compaction;

- laying sandbags along the crest;

- device reinforced concrete walls on the existing ridge.

The closest analogue (patent HU 0800458 A2, E02B 7/20, E02B 7/34, published March 29, 2010, author - KOZMA KAROLY [HU]) proposes the extension of the dam crest with flat sheets with a retaining frame made of tubular structures assembled in blocks, which differs significantly from the proposed utility model in terms of cladding and retaining frame materials, in the technology of manufacturing products and their installation, increased labor intensity, timing and cost of work.

The difference of the proposed utility model is

- speed of construction of the protective wall in emergency situations;

- the use of economical materials for the construction of a frame protective wall;

- ease of construction, without the use of lifting mechanisms, by a limited number of performers.

The technical result of the proposed utility model

Arrangement of a protective wall along the crest of existing dams to increase the throughput of rivers and canals in the event of a flood threat.

The objective of the technical result when using

Prompt erection of a protective wall along the crest of existing dams with a frame structure made of asbestos-cement pipes and cladding from galvanized profiled flooring.

Utility Model Feature

On the ridge of existing dams, vertical posts made of asbestos-cement pipes with a standard length of 4.0 m are installed in drilled 1 m deep boreholes and are tied in the transverse and longitudinal directions by segments of asbestos-cement pipes with a diameter of 100 mm and a length of 2.0 m.

The rigidity of the nodes is ensured by steel plates with bolted joints.

On racks facing the channel, lining of a galvanized C-shaped profile is attached to the screws, to which the lining of galvanized profiled sheet is installed.

Docking of the profiled sheet is carried out through a single wave with the filling of fiberglass impregnated with epoxy resin.

Utility Model Implementation

The proposed utility model can be implemented on any earthen protective dams in the event of a flood threat.
