Whole-body huddling dam and earth-rock dam body reinforcing and reconstructing device and construction method

Abstract

The invention discloses a whole-body huddling dam and earth-rock dam body reinforcing and reconstructing device and a construction method. The device comprises an earth-rock dam body, implanted steelpiles and a steel-concrete composite layer, wherein the implanted steel piles are densely distributed on the earth-rock dam body at different points, one end of each implanted steel pile is driven into the earth-rock dam body, the other end of each implanted steel pile is left on the surface of the dam body, the steel-concrete composite layer comprises gravel concrete and an anti-cracking steel mesh, the anti-cracking steel mesh covers the surface of the dam body and is fixed with the implanted steel piles, and the gravel concrete fills and covers the anti-cracking steel mesh. According to thedevice, the earth-rock dam body which maintains the stability of the dam body just by means of the friction cohesion characteristic and the self-weight compactness among original earth-rock sand-stone particles in the past and resists and prevents water pressure leakage, scouring and damage, the implanted steel piles and the steel-concrete composite layer form a full-body huddling structure, thefull-body clustering structure is formed in the mode that many chopsticks are combined, force is gathered and clustered, a firm dam similar to a rock mountain as a whole is formed, the shear resistance, the fracture resistance and the impact resistance of the dam are greatly improved, qualitative leap is achieved, and the dam can be seamless, has few seams and is attractive in surface.

Description

technical field [0001] The invention belongs to the technical field of construction, reinforcement and transformation of river reservoir dams and agricultural water canal dams, and relates to an earth-rock dam reinforcement and transformation device and method, in particular to a whole-body group dam and earth-rock dam reinforcement and transformation device and its construction method. Background technique [0002] Existing river reservoirs and agricultural water canal dams mostly exist in the form of earth-rock dams, which can be divided into three types: earth dams, earth-rock mixed dams and rockfill dams according to the material structure of the dam bodies. This kind of retaining dam body formed by throwing filling, accumulation, rolling, planning and other methods mainly relies on the frictional cohesion characteristics between the original soil sand and gravel particles and the density of its own weight to maintain the stability of its own dam body. And realize its r...

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.
