Problems solved by technology

However, it has the following disadvantages: when laying and installing, the tightness of the laying of multiple cylinder structures is poor, and there is no connection relationship between two adjacent components, which is not conducive to ensuring the tightness of its coverage, which may affect the sand-fixing ability of the components ;The fixing device only plays a fixed role and has a single function

Embodiment 1

[0037] A sand-fixing, tree-planting, rain-retaining, water-retaining and sand-controlling board, comprising a board body 1 and a fixing rod 2 with an equilateral triangle in cross section, such as figure 1 and figure 2 As shown, the center of the plate body 1 is provided with a circular planting hole 3 that runs through the upper and lower surfaces of the plate body 1. The plate body 1 surrounds the planting hole 3 to form three equally spaced top corners. The planting hole 3 The inner bottom is provided with an annular support sheet 4, the upper surface of the support sheet 4 is provided with a degradable base protective film 5, and the plate body 1 is laid with a regular hexagonal honeycomb structure;

[0038] Such as figure 1 and figure 2 As shown, the upper surface of the top corner part facing the planting hole 3 is provided with a rain collecting port 6, and the upper surface of the top corner part is an arc surface gradually lowering from its tip to the position of ...

Embodiment 2

[0047] The difference between this embodiment and embodiment 1 is:

[0048] In this example, if figure 2 As shown, the upper port of the planting hole 3 gradually lowers toward the inner circumference of the horizontal plane where the rain collecting port 6 is located along the edge. When it rains, it can reduce the amount of rainwater flowing into the planting hole 3 along the upper surface of the top corner of the plate body 1, so as to prevent excessive irrigation of rainwater.

[0049] In this example, if image 3 As shown, the free end of the positioning rod 17 is provided with a sharp portion. The sharp end of the positioning rod 17 is more conducive to inserting the positioning rod 17 into the sand, thereby promoting the fixing effect of the fixing rod 2 on the board body 1 .

[0050] In this example, if Figure 7 As shown, every six plate bodies 1 that form a regular hexagonal area include two types of plate bodies 1 with an equal number. The three connecting stri...

Abstract

The invention discloses a sand-fixing, tree-planting, rain-retaining, water-retaining and sand-controlling board, which belongs to the field of desert control facilities, and comprises a board body whose cross section is an equilateral triangle. The surface is provided with a rain-collecting port surrounding the planting hole, and the rain-collecting port is connected to an inclined rain-collecting channel. The rain-collecting channel is connected to the water storage chamber. It includes an inner rod and an outer tube. The lower end of the outer tube and the lower end of the inner rod are respectively hinged with a connecting rod and a positioning rod. The other end of the connecting rod is hinged at the middle of the positioning rod; A fixing hole matching the fixing rod is provided on the slat, and both the outer tube and the inner rod include a vertical fixing section and a rotating support section connected by a rotating shaft. The invention can realize better functions of windproof and sand-fixing and rain-collecting and water-retaining, and the fixing structure has triple functions of connecting board body, fixing board body and supporting trees, and has high application value.

Description

technical field [0001] The invention relates to the field of desert control facilities, in particular to a sand-fixing board for sand-fixing, planting, tree-collecting, rain-retaining, water-retaining and sand-controlling. Background technique [0002] Desert ecology is deteriorating, and dust and sandstorms are frequent, affecting social life and endangering economic development. With the trend of warming and drying the global climate, desert control is becoming more and more urgent. The arid sandy area has a dry climate, little rainfall, strong evaporation, strong winds, loose soil, and flowing sand. At present, people mainly use barriers to fix sand and plant trees and grass to curb the desertification process, and some results have been achieved. However, the desert area is vast and the natural conditions are complex. Except for a few areas that rely on abundant water resources and use engineering irrigation to make vegetation reconstruction better, in places where irrig...
