Reinforcing and Reconstruction Device for Whole-body Baotuan Dam and Earth-rock Dam

Abstract

The invention discloses a device and a construction method for the reinforcement and reconstruction of a whole-body hugging dam and an earth-rock dam body, comprising an earth-rock dam body, an implanted steel pile and a steel concrete composite layer; It is driven into the earth-rock dam body, and the other end is left on the surface of the dam body. The steel-concrete composite layer includes sand-gravel concrete and anti-cracking steel mesh. The anti-cracking steel mesh covers the surface of the dam body and is fixed with each implanted steel pile, and the sand-gravel concrete is filled and covered. Anti-cracking steel mesh; the structure of the present invention makes the original soil and rock that can maintain the stability of the dam body and can resist and prevent water pressure leakage, erosion and damage only by the friction and cohesion between the original soil sand and gravel particles and the self-weight compactness. The dam body, the implanted steel pile, and the composite layer of steel concrete form a whole-body hugging structure like "the chopsticks are united and cohesive together", forming a solid dam like a whole rock and mountain, making it shear, flexural, compressive, and impact resistant. Has been greatly enhanced and a qualitative leap, and can be seamless and less seam surface beautiful.

Description

technical field [0001] The invention belongs to the technical field of construction, reinforcement and reconstruction of dam bodies of rivers, reservoirs and agricultural water canals, relates to a device and method for reinforcement and reconstruction of earth-rock dam bodies, and in particular to a full-body hugging dam and a reinforcement and reconstruction device for earth-rock dam bodies and the like. its construction method. Background technique [0002] Existing river reservoirs and agricultural canal dams mostly exist in the form of earth-rock dams, which can be divided into earth dams, earth-rock mixed dams and rockfill dams according to the material structure of the dam body. This kind of retaining dam body formed by dumping, accumulation, rolling, planning and other methods mainly relies on the friction and cohesion between the original soil sand and gravel particles and the self-weight compactness to maintain the stability of its own dam body. And to achieve its...

Problems solved by technology

Although the former is of high quality and neatly stacked, it is time-consuming, labor-intensive, and expensive; although the latter has a stable structure and is quite satisfactory, the modeling and solidification process is complicated and expensive, and there are too many gaps in the building block combination and splicing of the front and rear. Disadvantages and problems such as straight and rigid appearance, lack of aesthetics, difficult construction, many safety hazards, high construction cost, waste of material resources, etc.
