specific Embodiment approach 1

[0026] Specific implementation mode one: refer to Figure 1 to Figure 7 Specifically illustrate this embodiment, a kind of anti-icing protection method of river bank in cold area described in this embodiment, it comprises the following contents:

[0027] First of all, under the condition of ensuring that the bank of the slope is smooth, the geotextile 3 is laid on the bank of the slope, and the bottom reinforcement mesh 7 is laid on the upper surface of the geotextile 3, and then a plurality of connection vertical bars 10 are arranged in a plum blossom shape and multiple connections are made. One end of the vertical bar 10 is welded on the bottom reinforcement mesh 7, and multi-layer stone masonry 2 is laid on the bottom reinforcement mesh 7;

[0028] Secondly, lay the top layer of steel mesh 8 on the paved masonry 2, and then weld the other ends of a plurality of connecting vertical bars 10 to the top layer of steel mesh 8. After the internal welding is completed, use a plura...

Embodiment

[0032] An anti-icing erosion protection method for riverbanks in cold regions. According to the design requirements, the sloped riverbanks are first cut, leveled, and compacted;

[0033] Lay geotextiles, bottom reinforcement mesh, stone masonry, top reinforcement mesh and concrete cover in sequence from the bottom to the top of the slope river bank. Among them, the bottom reinforcement mesh is required to be woven, the mesh size is 25cm×25cm, and spot welding is positioned; masonry If the size of the stone is greater than 30cm, it is required to prohibit riprapping during masonry to ensure that the surface of the stone masonry is flat and there are no large gaps; the top layer of steel mesh requires spot welding for positioning, and the mesh size is 50cm×50cm;

[0034] After laying the bottom reinforcement mesh, first weld a number of connecting vertical bars inside the bottom reinforcement mesh. In order to connect the bottom reinforcement mesh and the bottom layer to ensure t...

Abstract

The invention discloses an ice-erosion-prevention protection method of a cold-region river bank, and relates to the field of protection of floating ice impact. In order to solve the problems that an existing sticking slope type protection structure is light, thin, small in self weight, low in interface strength and free of effectively resisting ice floe impact, geotextile and a bottom layer reinforcing mesh are sequentially laid on the slope river bank from bottom to top; a plurality of connecting vertical ribs are arranged in a plum blossom shape and are welded to the interior of the bottom layer reinforcing mesh, stone masonry is placed, a top layer reinforcing mesh is laid, the multiple connecting vertical ribs are welded together, and a plurality of side sealing reinforcing steel bars are evenly welded between two outer sides of the laid top layer reinforcing mesh and the laid bottom layer reinforcing mesh and are used for sealing the stone masonry; the round faces of a plurality of semi-spherical steel shells are evenly welded to the top layer reinforcing mesh, a concrete cover face is adopted to cover the top layer reinforcing mesh, and the spherical faces of the multiple semi-spherical steel shells are exposed out; finally, slope shoulders and fixing feet are arranged on the top ends and the bottom ends of the slope river bank correspondingly in a built manner, the whole protection structure is built, and the method is used for ice impact and erosion prevention of the river bank.

Description

technical field [0001] The invention relates to a protection method applicable to preventing ice erosion of rivers in cold regions. It belongs to the field of protection against drift ice impact. Background technique [0002] The bank slopes of rivers above 30° north latitude in my country are generally damaged by ice floe impacts. The impact of ice floe on bank slopes along the way can directly cause river bank collapse or weaken the stability of river banks, resulting in soil erosion. At present, the protection of domestic bank slopes is mainly based on slope protection, and the main structures are dry stone, mortared stone, prefabricated concrete slabs, Renault pads and other structures. Therefore, during the drift ice period, serious damage will occur in the upstream and top thrust section of the river. Dry masonry, masonry masonry and precast concrete slabs are loose in structure, poor in integrity, and small in self-weight are the main reasons for their damage. Renau...
