Description

Technical Field

[0001] The utility model belongs to the technical field of water conservancy and hydropower engineering slopes, and in particular relates to a self-locking assembly frame slope protection. Background Art

[0002] Frame beam slope protection is widely used in slopes with poor stability. Its main function is to maintain the stability of the slope, prevent soil loosening and loss, and improve the integrity of the slope. In existing projects, frame beam slope protection adopts a variety of forms, which can be roughly divided into cast-in-place reinforced concrete structure and traditional prefabricated assembly. Cast-in-place reinforced concrete structure frame beam is widely used. The traditional construction process mainly includes foundation excavation, formwork support, steel bar binding, concrete pouring, formwork removal and maintenance, etc. The process is cumbersome and the quality is difficult to control. Traditional prefabricated assembly slope protection is mostly bonded by mortar or fixed by anchor rods. The connection between units is not firm, which is easy to slide and break, and the overall protection effect of the slope is not good.

[0003] The Chinese patent document with publication number CN105586853A discloses a combined concrete lattice slope protection and a construction method thereof. The combined precast concrete lattice slope protection structure includes a main block and a cushion block. The main block is approximately a cuboid structure, and the end faces of the cuboid are respectively formed by two mutually perpendicular end faces, and the two end faces are perpendicular to the bottom face of the cuboid; the cushion block is composed of a square (or rectangular) base and four square (or rectangular) bosses. The cushion blocks are distributed on the dam in a square shape, and the spacing between the cushion blocks is equal to the length of the main block. A main block is placed between every two cushion blocks to form a precast concrete lattice slope protection. However, the lattice slope protection structure of the document has the problem that it cannot be locked along the beam direction. If settlement occurs in this direction, the main block will slide down, resulting in discontinuity of the slope protection, and the problem that the connection between the units is not firm and easy to slide and break is not solved.
