Problems solved by technology

[0003]With the development of engineering science and technology, more and more people began to study structural types that can improve beach protection and bottom protection damage. In the late 1980s, domestic water conservancy Han Yingguan of the Northwest Institute of Water Conservancy Sciences of the Ministry of Finance and others proposed a permeable frame with four sides and six sides, which has been well applied in revetment reinforcement, but there are still some deficiencies in practical application, which are mainly reflected in the following two aspects: (1) In actual use, the four-sided and six-sided permeable frame needs 3 to 5 binding and throwing due to the weak connection between the four-sided and six-sided permeable frames. However, the overall stability is still insufficient, and displacement occurs under the action of water flow, which reduces the protective effect. ; (2) The welding joints of the four-sided and six-sided permeable frame members are easy to corrode and crack, and the members are scattered, resulting in complete destruction of the structure

Embodiment 1

[0025] like figure 1 As shown, the protective hook body includes an intermediate body 3, and the two ends of the intermediate body 3 have an open hook body 1 and a hook body 2. The hook body 1 is formed by connecting a bottom 11 to an inner arm 12 and an outer arm 13. A curved hook with an opening on the side, the inner arm 12 is connected to the intermediate body 3; the hook body 2 is a curved hook with an opening on one side formed by connecting a bottom 21 to the inner arm 22 and the outer arm 23, the inner arm 22 and the intermediate body 3 are connected, and the intermediate body 3 forms a space cube with the body 1 and the hook body 2.

[0026] The hook body 1 and the hook body 2 are composed of hollow columns, and the cross sections of the hook body 1, the hook body 2 and the intermediate body 3 are "U" shaped.

[0027] The inner walls of the hook body 1 and the hook body 2 are connected with a number of reinforcing ribs, the reinforcing ribs are two sets of tangent ci...

Embodiment 2

[0031] The cross section of hook body 1, hook body 2 and intermediate body 3 is a rectangular cross section. There are several reinforcing ribs connected to the inner walls of hook body 1 and hook body 2. The reinforcing ribs are grid-shaped. The space is detachable, the hook body 1, the hook body 2 and the intermediate body 3 are connected by a snap ring, and the rest are the same as in embodiment 1;

[0032] The material used for the protective hook body shown in this embodiment is plastic polypropylene+BaSO with a large specific gravity. 4 , the specific gravity is 2.0g / cm 3, the wall thickness of the connecting body is the same as that of the reinforcing rib, both are 4mm; the center of gravity of the space cuboid formed by the intermediate body 3, the hook body 1 and the hook body 2 falls on the geometric center of the space cuboid, and the radius is the dimension of the space cuboid A ball that is 1 / 8 of the sum of length, width and height, that is, the radius of the ce...

Embodiment 3

[0034] The cross section of hook body 1, hook body 2 and intermediate body 3 is a circular cross section. There are several reinforcing ribs connected to the inner walls of hook body 1 and hook body 2. The reinforcing ribs are in the shape of "Z". Between the body 3 is a circular arc transition section integrally formed, the rest is the same as embodiment 1;

[0035] The material used for the protective hook body shown in this embodiment is plastic polypropylene+BaSO with a large specific gravity. 4 , the specific gravity is 2.0g / cm 3 , the wall thickness of the connecting body is the same as the thickness of the reinforcing rib, both are 2mm; the center of gravity of the space cube formed by the intermediate body 3, the hook body 1 and the hook body 2 falls on the geometric center of the space cube as the center, and the radius is the dimension of the space cube The ball is 1 / 12 of the sum of the lengths of the three sides, that is, the radius R of the center of gravity ball...

Abstract

The invention discloses a protective hook-connected body, which comprises an intermediate body. Both ends of the intermediate body have hooks with openings. The intermediate body and the hook body form a space quadrilateral. It is inside a sphere that is 1 / 8 of the sum of the length, width and height of the space cube. There is no need to add other constraints between the units of the hook-connected body of the present invention. Through throwing, the units can be actively connected with each other, and the integrity is better. The throwing area of ​​the hook-connected body forms a porous structure, which can effectively reduce the water flow and play a role. To the effect of energy dissipation and anti-shock. Limiting the range of the center of gravity of the space cube can improve the hooking ability between the hooking units. If they are randomly placed, they can be easily linked to each other, and it is more difficult to separate. It can be widely used in shore beach protection, bridge pier protection, and waterway protection. and construction of dams.

Description

technical field [0001] The invention relates to a protective structure, in particular to a protective hook-connected body in which the components themselves can be hooked separately in the state of loose throwing. Background technique [0002] The past examples of waterway protection projects show that the destruction of the beach protection or bottom protection in the waterway protection buildings is one of the main reasons for the damage of the protection buildings and the instability of the beach and water. At present, most of the protection measures for the beach and the foundation sand body of the protective building from erosion are to use the weight of the beach or bottom protection body to maintain the stability of the beach or bottom protection. This kind of completely passive protection, under the condition of relatively high water flow, due to the pulsation of the water flow and other reasons, it is more common to cause local washing on the edge of the row or betw...
