Fig. 1 is a sectional view of a silt dam of the present invention stacked with box-type net molds.
Fig. 2 is a perspective view of the box net form of fig. 1.
[ 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.
