Abstract

The invention relates to the field of side slope protection precast blocks, in particular to a precast block with drainage holes. The precast block with the drainage holes comprises a precast block body and drainage holes, the drainage hole penetrates through the prefabricated block, and a sleeve is arranged on the inner wall of the drainage hole; when the precast block is laid on the side slope, the included angle beta between the axial direction of the drainage holes and the direction perpendicular to the ground ranges from 80 degrees to 85 degrees. The embodiment of the invention provides a precast block with water drainage holes, and aims to solve the problem that a laid finished six-edge block and a broken stone hardcore are easily damaged and the water drainage function of a cone is influenced due to the fact that the precast block is drilled on site in the related technology.

Description

technical field [0001] The present application relates to the field of slope protection prefabricated blocks, in particular to a prefabricated block with drain holes. Background technique [0002] At present, the slope protection project includes plant protection and engineering protection. Among them, the prefabricated block is often used to lay the slope protection in the engineering protection, and the prefabricated block needs to be opened with a scupper. Otherwise, if there is water seepage in the slope, the slope will be soaked for a long time. Cause the slope to be unstable and easy to be washed or collapsed. [0003] In the related art, the method of laying prefabricated hexagonal blocks first, and then uniformly drilling scuppers according to the requirements of the design spacing is usually adopted in the construction of the abutment and culvert cone slope protection in China. However, on-site drilling is easy to damage the finished hexagonal blocks and gravel cus...
