Embodiment

[0022] Example: such as Figure 1-4 As shown, this embodiment specifically relates to a mobile in-situ rapid drug injection method for contaminated sites, including the following steps:

[0023] (1) if Figure 4 As shown, based on the pollution investigation data, the pollution type and degree of pollution of the site are clarified, the scope of the polluted area of ​​the site is determined 21, and the scope of the severely polluted area 22 and the distribution area of ​​dark bangs 23 are divided;

[0024] (2) if Figure 4 As shown, a number of injection points 20 are evenly arranged within the scope of the site pollution area 21, and the layout spacing is determined according to the actual situation of the site. In this embodiment, the layout spacing between the injection points 20 is 3m*3m. 22 and the dark bang distribution area 23 are densely distributed, and the layout spacing is 2m*2m;

[0025] (3) if Figure 1-3 As shown, the mobile rapid injection equipment is insta...

Abstract

The invention discloses a mobile in-situ rapid injection method for contaminated sites, which comprises the following steps: determining a number of injection points in the repair area of ​​the contaminated site; moving a car body with a mechanical arm into the repair area, A front-end injection device is installed at the end of the mechanical arm, and the front-end injection device is an injection tube coaxially arranged with the mechanical arm; the injection tube is vertically pressed into the injection tube by the mechanical arm. The specified depth of the soil at the point, and pump the agent into the injection pipe so that the agent penetrates into the surrounding soil for repair; after the injection is completed, the injection pipe is lifted up and moved to the next injection point, so reciprocating, Complete the injection of all injection points. The advantage of the present invention is that it realizes the integrated in-situ injection without the need to build wells and use multiple equipment, making the construction more efficient, safer and simpler; with the help of the telescopic function of the hydraulic telescopic rod, it is ensured that the front-end injection device can reach a larger construction depth.

Description

technical field [0001] The invention belongs to the technical field of pollution remediation, and in particular relates to a mobile in-situ rapid drug injection method for polluted sites. Background technique [0002] With the rapid development of urban construction, the demand for the control and restoration of groundwater and soil pollution is increasing. Among them, in-situ restoration is more economical than ex-situ restoration, avoids excavation and transportation, and reduces the risk of secondary pollution. It has become a hot spot for future restoration technology selection. Restoration and treatment technologies mainly include heat treatment, biological method, chemical oxidation method, multiphase extraction and other technologies. Chemical oxidation technology has quick results and controllable costs, and has been widely used in on-site engineering restoration. According to the embodiment, it is divided into in-situ injection and in-situ stirring. [0003] In or...
