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

[0027] Such as 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, hook body 1, hook body 2 and intermediate body 3 form a space cube.

[0028] 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.

[0029] 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 circular arcs u...

Embodiment 2

[0033] 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;

[0034] 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 hook body is the same as the thickness of the reinforcing rib, both are 4mm; the side length of hook body 1 and hook body 2 is 400mm*300 mm, the length of intermediate body 3 is 480mm, and the cross-sectional area of ​​hook body 1 and hook body 2 is 40mm* 30mm, the length of the intermediate body: the side length of the hook body is 1.2:1. After the assembly of the hook body ...

Embodiment 3

[0036] 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;

[0037] The material used for the protective hook connecting body shown in this embodiment is plastic polypropylene+BaSO with large specific gravity 4 , the specific gravity is 2.0g / cm 3 , the wall thickness of the hook body is the same as the thickness of the reinforcing rib, both are 2mm; the side length of the hook body 1 and the hook body 2 is 600mm*300mm, the length of the intermediate body 3 is 480mm, and the cross-sectional area of ​​the hook body 1 and the hook body 2 is 3600mm 2 , The length of the intermediate body: the side length of the hook body is 0.8:1. After the assembly of the hook body is completed, the...

Abstract

The invention discloses a protective hooking body. The protective hooking body comprises a middle body. Opened hook bodies are arranged at two ends of the middle body, and the ratio of the length of the middle body and the side length of the hook bodies is 1.2:1-0.8:1. Other restraining devices do not need to be added between hooking body units, the hooking body units can be automatically hooked by being cast, integrity is good, a casting area of hooking bodies forms a porous structure, water flow can be effectively reduced, and the functions of energy dissipation and erosion control can be achieved. The ratio of the length of the middle body and the side length of the hook bodies is limited, hooking capacity of the hooking body units can be improved due to the structure, the hooking body units can be easily hooked with each other when randomly placed, separation of the hooking body units is difficult, and the protective hooking body can be widely used in engineering construction of bank protection, bridge pier protection, navigation channel protection, dams and the like.

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 bet...
