Problems solved by technology

The bottom plates of these nut blocks are poured with concrete and the block as a whole. Because there are many small drainage holes, it is difficult to prefabricate the demoulding and the quality is difficult to guarantee; and the water permeability of the nut block after the bottom seal becomes poor, and the block is easy to suck out destroy

Abstract

The invention provides a permeable cup-shaped nut block and a prefabricating method thereof. The permeable cup-shaped nut block comprises a nut block body and a three-impeller permeable board; the three-impeller permeable board is connected with the nut block body in an embedded mode; and the three-impeller permeable board comprises a circular disc, a first impeller, a second impeller and a thirdimpeller. Compared with traditional technologies, through the additional arrangement of three clamping grooves which are formed in the bottom of the nut block body at interval, a stone subcrust is cancelled; through the additional installation of the three-impeller permeable board on the clamping grooves, the use amount of aggregates is reduced, the manufacturing procedures are simplified, and thepurposes of realizing free permeability of air and water and improving the wave attenuating ability and stability are achieved; and soil can be filled in a cavity in the nut block body for greening,so an effect of better ecological landscape is realized.

Description

technical field [0001] The invention relates to a face protection block of seawall, revetment and breakwater engineering, in particular to a permeable cup-shaped nut block and a prefabrication method thereof. Background technique [0002] Most protective projects such as dikes, breakwaters, and bank revetments in coastal areas use artificial block face protection to weaken the impact of waves, reduce wave climbing, and reduce wave damage to building structures. Among them, the nut block face shield imported from abroad in the 1980s is widely used in seawall projects in Shanghai and Jiangsu due to its neat and beautiful appearance, simple and unified installation, relatively mature research results and design methods. [0003] Since the nut block is provided with up and down through wave-dissipating holes, in order to protect the internal soil, a rock cushion, crushed stone and geotextile filter layer are generally provided under the nut block. In the past ten years, in orde...
