Large-angle high-thickness slope surface concrete pouring graded grid

Abstract

The invention discloses a large-angle high-thickness slope surface concrete pouring graded grid. The large-angle high-thickness slope surface concrete pouring graded grid is composed of meshes and a supporting mounting system; the supporting mounting system is paved along the slope surface, and galvanized electrowelding steel wire gauze is adopted in the meshes; and the width of the graded grid isslope surface concrete thickness minus the thickness of an upper protective layer and a lower protective layer and the diameter of an upper layer of steel bars and a lower layer of the steel bars, aninterval of the meshes placing is determined through the galvanized steel wire mesh theory maximum ash blocking quantity water level and a perpendicular distance from a slope surface intersection tothe meshes, so that the meshes better block ash, and the concrete slope slipping phenomenon is controlled. According to a field slope surface structure, the limitation of concrete pouring slump limitand the pouring procedure of concrete, the concrete is poured in two layers, and vertical partition meshes are arranged and pouring is carried out by dividing left and right parts of each layer. Whenthe concrete is poured, pouring phenomena of large area and high pressure do not exist, and the slope surface is stable. The problems of increased operating personnel operating quantity, slow construction speed, low efficiency, prolonged construction period and the like are solved.

Description

technical field [0001] The invention relates to the fields of water conservancy and municipal engineering, in particular to a large-angle and high-thickness concrete pouring grid. Background technique [0002] In the slope construction of water conservancy and municipal engineering, large-angle and high-thickness reinforced concrete slopes are often encountered. During the construction process, due to the steep slope and large slope thickness, it is difficult to control the flow of concrete along the slope direction. During the construction, a large amount of flow falls, which leads to problems such as exposed steel bars, poor flatness, super high bottom, and waste of materials. Secondly, the falling concrete needs to be transported twice by construction workers, resulting in increased workload of operators, slow construction speed, low efficiency, and extended construction period. [0003] Chinese patent 201520724556.5 discloses a steel structure suitable for repairing wed...
