Orthogonal reinforced concrete abatis and preparation method thereof

Abstract

The invention relates to an orthogonal reinforced concrete abatis and a preparation method thereof. The orthogonal reinforced concrete abatis is formed by connecting three reinforced concrete rod pieces of the same length perpendicularly and orthogonally and refers to a structural unit with a certain space. The orthogonal reinforced concrete abatis is characterized in that the three reinforced concrete rod pieces are perpendicularly and orthogonally connected in the following way that the three reinforced concrete rod pieces are perpendicularly fixed with one another by metal connectors at thepositions nearby the length midpoint of each reinforced concrete rod piece. The orthogonal reinforced concrete abatis is simple in structure, and raw material cost can be reduced. The orthogonal reinforced concrete abatis consists of square reinforced concrete rods of the certain specifications and thus can be processed conveniently at the place where raw materials are abundant, and manufacturingand transportation cost is reduced. Transportation, loading and unloading are facilitated. The abatis can be made by means of simple assembling after the raw materials arrive at the construction site, and hence assembling and construction cost is reduced. The protective effect on a riverbed is equal to that of a concrete six-sided tetrahedron.

Description

technical field [0001] The invention relates to a water conservancy facility, in particular to a reinforced concrete orthogonal mosaic in river bank revetment and bridge pier protection projects. The invention also relates to a preparation method of the reinforced concrete orthogonal mosaic. Background technique [0002] River revetment engineering facilities are divided into two types: physical anti-scour revetment facilities and deceleration non-scour revetment facilities. Among them, the deceleration and non-scouring revetment facilities are generally light renovation buildings. For example: wooden branches, hanging willows, reinforced concrete grid rows, etc. These facilities can locally change the water flow pattern, reduce the flow velocity in the protected area, change the erosion and silting situation, and achieve the effect of silting and slope protection. However, wooden branches and hanging willows are easy to rot and wash away, and the maintenance work require...

[0006] However, the above-mentioned reinforced concrete tetrahedral hexagon permeable frame structure is composed of six concrete rods. After the concrete rods are transported to the construction site, four nodes of the frame need to be welded, and three rods at each node are welded to form a tetrahedron hexagon. The permeable frame structure has high working intensity; a
