Problems solved by technology

Existing methods such as in-situ sand fixation and spraying have certain limitations in the desert environment. For example, the uniformity of the surface coating of the spraying method is poor, and it is easy to have weak reinforcement areas; in addition, the spraying method only forms a layer on the surface of the desert. The solidified thin layer has weak mechanical properties and is easily damaged under human and mechanical disturbances, which is not conducive to long-term effective windproof and sand fixation

Embodiment 1

[0027] The present embodiment provides a kind of windproof and sand-fixing method of farming type microbial treatment desert surface, it is characterized in that:

[0028] Construction is carried out by using a tillage vehicle 3 mainly including a microbial solution storage tank 4 , a cementation solution storage tank 5 and tillage and spraying equipment 10 .

[0029] The main part of the tillage vehicle 3 is a vehicle frame with a walking system. The microbial solution storage tank 4 and the cementing liquid storage tank 5 are installed on the vehicle frame.

[0030] A stirring tank 8 is also installed on the vehicle frame. The liquid inside the microbial solution storage tank 4 and the cementing liquid storage tank 5 is pumped into the stirring tank 8 through the 1# water pump 6 and the 2# water pump 7 respectively. After being stirred by the stirring device inside the stirring tank 8 , the liquid inside the stirring tank 8 is supplied to the tillage and spraying equipment...

Embodiment 2

[0041] The main technical solution of this embodiment is the same as that of Embodiment 1. Further, the main part of the farming vehicle 3 is a frame with a walking system. The microbial solution storage tank 4 and the cementing liquid storage tank 5 are installed on the vehicle frame.

[0042] A stirring tank 8 is also installed on the vehicle frame. The liquid inside the microbial solution storage tank 4 and the cementing liquid storage tank 5 is pumped into the stirring tank 8 through the 1# water pump 6 and the 2# water pump 7 respectively. After being stirred by the stirring device inside the stirring tank 8 , the liquid inside the stirring tank 8 is supplied to the tillage and spraying equipment 10 through the 3# water pump 9 .

[0043] The front end of the vehicle frame is tillage and sprinkler equipment 10 . The tillage and spraying equipment 10 includes a plow frame and several plowshares 14 . The plow frame 13 of the tillage and spraying equipment 10 includes a sp...

Abstract

The invention discloses a method for preventing wind and stabilizing sand on a desert surface through tillage type microbiological treatment. Two storage tanks are carried at the front part of the tillage vehicle and are respectively used for storing a microbial solution and a cementing solution; a stirring tank is fixed to the rear portion of the tillage vehicle, a water suction pump is used for sucking a microbial solution and a cementing solution into the stirring tank to be stirred, the water suction pump is used for pumping out a mixed solution in the stirring tank, and the mixed solution is connected with tillage and spraying equipment through a conveying pipeline. According to the scheme, microorganisms can be effectively introduced into a desert soil body, and the uniformity is better; in addition, a plowing method is adopted for reinforcement, pipelines do not need to be disassembled after maintenance is finished, and manual disturbance can be reduced; and the plowing method is adopted for reinforcement, so that the reinforcement depth can be effectively increased, and the physical disturbance resistance of solidified soil is enhanced.

Description

technical field [0001] The invention relates to a cultivation type desert surface sand-fixing construction equipment and method based on microbial mineralization, belonging to the field of desert control. Background technique [0002] Land desertification has caused serious adverse effects on the human living environment. [0003] Desertification control is an important part of desertification control. Existing methods such as in-situ sand fixation and spraying have certain limitations in the desert environment. For example, the uniformity of the surface coating of the spraying method is poor, and it is easy to have weak reinforcement areas; in addition, the spraying method only forms a layer on the surface of the desert. The solidified thin layer has weak mechanical properties and is easily damaged under human and mechanical disturbances, which is not conducive to long-term effective windbreak and sand fixation. Contents of the invention [0004] The object of the prese...
