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

[0026] Such as figure 1 As shown, the protective hook body includes an intermediate body 3, and the two ends of the intermediate body 3 are connected to the hook body 1 and the hook body 2 with openings, and the hook body 1 and the hook body 2 are composed of hollow columns.

[0027] The hook body 1 is a curved hook with an opening on one side formed by connecting a bottom 11 to an inner arm 12 and an outer arm 13 , and 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 an inner arm 22 and an outer arm 23 , and the inner arm 22 is connected to the intermediate body 3 . The intermediate body 3 has the same length as the bottom 11, the inner arm 12, the outer arm 13 of the hook body 1, the bottom 21, the inner arm 22, and the outer arm 23 of the hook body 2, and the hook body 1, the hook body 2 and the intermediate body 3 form a Space cube, hook body 1, hook body 2 and inter...

Embodiment 2

[0032] 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, hook body 1, hook body 2 and intermediate body 3 are connected by a sheath, and the rest are the same as in embodiment 1;

[0033] 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 2.0 g / cm 3 , the wall thickness of the connecting body is the same as the thickness of the reinforcing rib, both are 4mm. The area of ​​hook body 1 is 400mm*400mm, the cross-sectional area of ​​hook body 1 is 40mm*20mm, the ratio of the area of ​​hook body 1 to the cross-sectional area of ​​hook body 1 is 200:1, the area of ​​hook body 2 is 400mm*400mm, and the cross-sectional area of ​​hook body 2 It is 40mm*20mm, and the ra...

Embodiment 3

[0035]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". Body 3 is integrally formed, and the rest are the same as embodiment 1;

[0036] 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 2.0 g / cm 3 , the wall thickness of the connecting body is the same as that of the reinforcing rib, both are 2mm. The area of ​​the hook body 1 is 600mm*300mm, and the cross-sectional area of ​​the hook body 1 is 3600mm 2 , the ratio of the hook body 1 area to the hook body 1 cross-sectional area is 50:1, the hook body 2 area is 600mm*300mm, and the hook body 2 cross-sectional area is 3600mm 2 , The ratio of the hook body 2 area to the hook body 2 cross-sectional area is 50:1. After the hook bod...

Abstract

The invention discloses a protective hooking body. The protective hooking body comprises a middle body. Two ends of the middle body are connected with hook bodies which are respectively provided with an opening, the middle body and / or the hook bodies are composed of hollow cylindrical bodies, the size of a closed plane formed by end-to-end connection of the hook body is the hook body size, the cross sectional size of the hook body cylindrical body is the hook body cross sectional size, and the ratio of the hook body size and the hook body cross sectional size is 50:1-200:1. 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 hook body size and the hook body cross sectional size is limited in a specific range, the structure can not deform easily and has good strength, and the protective hooking body can be widely used in bank protection, bridge pier protection, navigation channel protection, and engineering construction of dams and the like.

Description

technical field [0001] The invention relates to a protective hook-connected body, in particular to a protective hook-connected body in which the components themselves can be hooked separately in a scattered throwing state. 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 r...
