Problems solved by technology
[0004] The key of the direct-push injection technology lies in the injection drill. The traditional direct-push injection drill uses the drill itself as the cavity for injecting the agent. Due to the poor corrosion resistance of the drill itself, it is impossible to inject strong corrosive agents; and the injection drill on the corresponding drill Lack of protection when drilling into subsurface soil, easily clogged by soil and prevents effective injection

Embodiment Construction
[0021] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be described in detail below in conjunction with the embodiments and accompanying drawings.
[0022]
[0023] figure 1 It is a flow chart of the soil directional, fixed-point and precise injection method in the embodiment of the present invention.
[0024] Such as figure 1 As shown, this embodiment provides a method for directional and fixed-point precise injection of soil, comprising the following steps:
[0025] Step 1, using the injection device 100 with a drill bit and in a sealed state to drill in the target area to form a drill hole;
[0026] Step 2, making the injection device 100 in a sealed state arrive at a designated position in the borehole;
[0027] Step 3, switch the working state of the injection device 100 to the injection state (i.e. from Figure 4 The state in the switch to image 3 state), s...

The invention provides a directional and fixed-point precise injection method for soil, and belongs to the field of soil remediation. The invention provides a directional and fixed-point accurate injection method for soil, which is used for injecting soil remediation liquid into soil in a target area through an injection device. The working states of the injection device at least comprise a sealed state for storing the soil remediation liquid and an injection state for injecting the soil remediation liquid into the soil. The method comprises the steps of: 1, drilling in the target area to form a drill hole; 2, enabling the injection device in the sealed state to be located in the drill hole; and 3, switching the working state of the injection device into an injection state, so as to enable the soil remediation liquid to overflow into the soil from the injection device. According to the directional and fixed-point accurate injection method for soil, the injection hole of the injection device cannot be blocked by the soil in the using process, and therefore efficient directional and fixed-point accurate injection can be achieved.
Description
technical field [0001] The invention relates to the field of soil restoration, in particular to a method for directional, fixed-point and precise injection of soil. Background technique [0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, reduce and transform pollutants in the soil to reduce their concentration to an acceptable level, or to convert toxic and harmful pollutants into harmless ones. substance. Fundamentally, the technical principles of contaminated soil remediation can include: [0003] Change the form of pollutants in the soil or the way they combine with the soil to reduce their mobility and bioavailability in the environment; reduce the concentration of harmful substances in the soil. [0004] The key of the direct-push injection technology is the injection drill. The traditional direct-push injection drill uses the drill itself as the cavity for injecting the agent. Due to the poor corrosion resista...
