Problems solved by technology

[0004] Soil compaction is one of the important manifestations of soil degradation, especially the subsurface soil compaction, which restricts the growth of plant roots underground. In the middle and late stages of plant growth, if there is little rainfall and high evaporation, soil compaction seriously affects the water absorption of plants. making the soil unfit for plants

Embodiment 1

[0048] Such as figure 1 As shown, a clamping sleeve for soil improvement construction, the clamping sleeve 1 includes a first clamping plate 2 and a second clamping plate 3, the first clamping plate 2 and the second clamping plate 3 have a C-shaped section, and the first clamping plate 2 It is arranged symmetrically with the second splint 3 . The first splint 2 and the second splint 3 are rotationally connected, and the connection point is located on the outer side of the first splint 2 and the second splint 3 . When both ends of the first splint 2 and the second splint 3 abut against each other, a circular groove 4 is formed on the inner walls of the first splint 2 and the second splint 3 . Both the inner walls of the first splint 2 and the second splint 3 are provided with a flexible rubber layer 5 .

[0049] Such as figure 2 As shown, the side wall of the first splint 2 away from the rotating end is provided with a slot 6 , the slot 6 faces the second splint 3 , and the...

Embodiment 2

[0054] A soil improvement method, comprising the steps of:

[0055] S1, such as image 3 As shown, the vacuum tube 17 is inserted in the original soil layer by a drilling rig; the vacuum tube 17 is evenly distributed with several roots in the original soil layer, and the lower end of the vacuum tube 17 is fixedly equipped with a drill bit 17.1, so that the vacuum tube 17 is inserted in the original soil layer; Figure 4 As shown, the side wall of the vacuum tube 17 is provided with a through hole 18, and the through hole 18 is provided with a breathable water-proof membrane 19; as image 3 As shown, the vacuum tube 17 is provided with a regulating valve 20, and the regulating valve 20 can be used to control the opening of the vacuum tube 17;

[0056] S2, such as image 3 As shown, a sponge layer 21 and a sandstone layer 22 are sequentially laid on the original soil layer; the sponge layer 21 is filled with a soil improvement solution for improving the compaction of the origi...

Abstract

The invention discloses a soil improvement method. The method includes the following steps of S1, inserting a vacuum pipe into an original soil layer; S2, laying a sponge layer, a sand stone layer anda sealing membrane on the original soil layer in sequence; S3, making the vacuum pipe penetrate through a through groove; S6, installing a vacuum pump at one end of the vacuum pipe, and turning on the vacuum pump, wherein a soil improvement liquid in the sponge layer is pressed into the original soil layer by barometric pressure under driving of the vacuum pump, so that the pores of a hardened soil layer are enlarged, and the moisture of the hardened soil layer is increased; S7, sequentially detaching the vacuum pump, the sealing membrane, the sand stone layer, the sponge layer and the vacuumpipe; S8, utilizing a rotary cultivator to plough land, applying organic fertilizer onto the soil layer, and additionally laying a layer of loose soil on the organic fertilizer. During function of the vacuum pump, air pressure in the soil can be reduced, the soil improvement liquid in the sponge layer permeates into the original soil layer under the action of the barometric pressure, and therefore hardening of the soil layer is alleviated. Meanwhile, during permeation of the soil improvement liquid, the pores of the original soil layer can be enlarged, so that more convenience is provided forfollowing plough when hardening of the soil is alleviated.

Description

technical field [0001] The invention relates to the technical field of soil improvement, in particular to a soil improvement method. Background technique [0002] Soil compaction is an important problem in the sustainable development of agriculture. [0003] As countries around the world pay more and more attention to the sustainable development of agriculture, higher requirements are put forward for the sustainability of soil production capacity. Especially in the severe situation of my country's large population, little arable land, and food security, how to ensure the sustainable production capacity of soil is particularly important. [0004] Soil compaction is one of the important manifestations of soil degradation, especially the subsurface soil compaction, which restricts the growth of plant roots underground. In the middle and late stages of plant growth, if there is little rainfall and high evaporation, soil compaction seriously affects the water absorption of plant...
