[ detailed description ] embodiments

Referring to the attached drawings 1 and 2 in the specification, the utility model relates to a siltation dam stacked by box type net moulds, which is constructed by a dam foundation 1, a side slope, a plurality of box type net moulds 3 and the like.

Wherein the side slopes (not shown) are located above two sides of the dam foundation 1. The dam foundation 1 and the side slope are recessed to form a limiting groove 2, and the limiting groove 2 can be formed by adopting a manual excavation or ramming mode; the box-type net mould 3 at the lowest layer is partially sunk in the limiting groove 2, so that the box-type net mould 3 is limited, and the box-type net mould 3 is prevented from shifting. The concave depth of the limiting groove 2 is not less than 30cm, and the limiting groove is arranged along the length direction of the silting dam.

The box-type net moulds 3 are stacked between the dam foundation 1 and the side slope layer by layer. The upper and lower adjacent two layers of box-type net moulds 3 are arranged in a staggered way. In this embodiment, the box type net formwork 3 has a hollow rectangular structure and an open top surface, so as to be filled with sandstone 4, and the box type net formwork 3 is stacked layer by layer, and the open top surface of the box type net formwork in the lower layer is closed by the bottom surface of the box type net formwork in the upper layer.

The box-type net mold 3 comprises a steel reinforcement framework 31, and a ribbed net 33 is bound on four outer side faces and a bottom face of the steel reinforcement framework 31 through steel wires 32, which can be seen from the attached figure 2 in the specification, wherein only a part of the ribbed net 33 is shown in the figure. The steel reinforcement framework 31, the steel wires 32 and the reinforced net 33 are light in weight and convenient to carry, so that the steel reinforcement framework, the steel wires 32 and the reinforced net are convenient to transport to a construction site for assembling.

The box type net formwork 3 is filled with the sandstone 4, the structural strength of the dam body can be greatly improved, and the sandstone 4 is restrained by the ribbed net 33 of the box type net formwork 3.
