Embodiment Construction

[0019] As shown in the figure, the serial net cage 1 for making sand barriers, sand retaining dams, sand dikes and sand walls is composed of the front side 2 of the net cage, the back side 3 of the net cage and the bottom surface 4 of the net cage to form a triangular cage body; The cage body is made into an equilateral triangle, and the height of the cage body is designed to be less than 90cm. The top edge of the front and the top edge of the back of the cage can be opened or closed and fixed. The front 2 and the back of the cage 3 The inner liner has geotextile 5. Arrange and connect the series net cages for making sand barriers in the desert according to the design of sand barriers, open the top side of the net cage to fill the net cage with desert sand to meet the design requirements, and close the top side to form a net cage sand barrier. To make the series-connected cages for the sand control dam, the cage body is made into an isosceles triangle, and the height of the c...

Abstract

The invented method provides a series mesh cage for constructing sand barriers, sediment storage dams, sand banks and sand walls, comprising a triangular cage body composed of a mesh cage front surface 2, a mesh cage rear surface 3, and a mesh case bottom surface 4, the inner of the front surface 2 and rear surface 3 of the mesh cage have earthwork cloth liners 5. The series mesh cage is used to construct sand barriers, sediment storage dams, sand banks and sand walls. Thereby sand in desert is used as building material for fathering desert. The invented mesh cage can be produced mechanically in large scale, and sand barriers, sediment storage dams, sand banks and sand walls made of mesh cages can be constructed mechanically.

Description

technical field [0001] The invention relates to the field of engineering technology, in particular to a series-connected net cage for making sand barriers, sand retaining dams, sand ditches and sand walls. Background technique [0002] Driven by storms, desert quicksand continuously intrudes into the grasslands and cultivated land on the edge of the desert. In the past few years, the area of ​​a county in my country was encroached by the desert every year. The construction of roads and railways that go deep into the hinterland of the desert not only has to face the problem of desert sand dunes piled up on the roadbed under the action of strong winds, but also has to face the problem of subgrade protection and subsidence of beach roads. At present, the method of using straw and treetop cuttings to make sand barriers to block quicksand can block quicksand to a certain extent, but cannot completely prevent quicksand from invading, and the long-distance transportation of straw i...
