Description

Hydraulic engineering flood prevention emergency precast block

Technical Field

The utility model belongs to the technical field of hydraulic engineering, especially, relate to a hydraulic engineering flood prevention precast block that speedily carries out rescue work.

Background

In the hydraulic engineering project, important flood control projects need to reserve certain flood control emergency materials, and the rock block is one of the main emergency materials. The exploitation of the rock block inevitably causes environmental pollution to a certain extent, and the excessive exploitation even causes environmental damage. In recent years, the country pays more and more attention to environmental protection, and the quarrying is limited, so that the supply of the quarrying in partial regions is in short supply. And the gravity center of the block stone is centered, and the block stone is easy to roll under the impact of water flow.

Detailed Description

In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings.

Referring to fig. 1-4, a water conservancy flood prevention and emergency rescue precast block comprises a block body, wherein the block body is an octahedron, the octahedron comprises four hexagonal surfaces 2 with the same size and four equilateral triangle surfaces 3, the hexagonal surfaces 2 are formed by connecting three long sides 6 with the same length and three short sides 7 with the same length end to end, the long sides 6 are connected with the short sides 7 end to end, an included angle between the adjacent long sides 6 and the short sides 7 is 120 degrees, six long sides 6 are used as extension lines to form a regular tetrahedron, and a lifting hook 4 is arranged on the equilateral triangle surface 3.

Furthermore, a reinforcing mesh 5 is arranged on the lower layer of the hexagonal surface 3.

Furthermore, the number of the lifting hooks 4 is four, and the lifting hooks are respectively anchored on the four equilateral triangle faces 3.

Furthermore, the top of the lifting hook 4 is an arch 41, and the bottom of the lifting hook 4 is provided with a left and a right symmetrical bottom hooks 42 which are bent outwards.

Furthermore, the lifting hook 4 is made by bending a steel bar.

When in manufacturing, the top of the steel bar is bent into an arch 41, the bottom is bent upwards and outwards, and the steel bar is symmetrically formed left and right to form a bottom hook 42, so that the lifting hook 4 is manufactured;

four reinforcing steel bar meshes 5 which have the same shape as the hexagonal surface and are slightly smaller in area are overlapped together, the long sides of two adjacent reinforcing steel bar meshes 5 are connected together by reinforcing steel bars to form a reinforcing steel bar framework, and the short sides form an equilateral triangle;

installing lifting hooks, wherein bottom hooks 42 of the lifting hooks are respectively hooked on the reinforcing steel bar meshes 5 on the two sides;

assembling a mould and placing the mould on a vibration table, wherein the inner structure surface of the mould comprises three hexagonal surfaces and four equilateral triangle surfaces, and the shape and the area of the inner structure surface are respectively the same as those of the hexagonal surfaces 2 and the four equilateral triangle surfaces 3;

and placing the steel reinforcement framework provided with the lifting hook into a mould, pouring concrete, vibrating for compacting, maintaining for 3-7 days, and demoulding to obtain the water conservancy project flood prevention and emergency rescue precast block.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all the modifications and equivalents of the technical spirit of the present invention to any simple modifications of the above embodiments are within the scope of the technical solution of the present invention.
