Problems solved by technology

[0004] The injection rod direct-push repair agent injection device is usually composed of a separate agent mixing barrel on the ground, an injection pump, an injection rod pressing device, an injection rod, and an injection head. Manual assembly and connection are generally used between various devices, and the integration degree is poor. When replacing the injection area, it is often necessary to move the equipment separately and reassemble the equipment. The overall mobility and flexibility are poor, and it cannot serve repair projects with tight schedules.
[0005] In the implementation of the restoration project using the direct-push agent injection process, the injection construction parameters such as injection volume, injection pressure and flow rate are mainly designed and determined based on the overall parameters of the site determined by the results of the preliminary engineering geological survey, which is limited by th

Embodiment 1

[0056] An in-situ agent injection restoration method for soil and groundwater pollution, using integrated equipment for in-situ agent injection restoration.

[0057] The equipment includes power system, detection system, injection system, dispensing system and auxiliary system. Power system includes fuel engine 1-1, power control mechanism 1-2, gearbox and generator 1-13; detection system includes probe 4-4, probe rod 4-3, data cable and computer 4-5; injection system Including plunger pump 2-5, injection rod 4-1, injection head 4-2, injection control mechanism and injection trolley platform 2-2; the dispensing system includes drug dissolving tank 3-5, stirring mechanism 3-2, adding The medicine metering mechanism and the dispensing trolley platform 3-7; the auxiliary system includes a rod box 1-8, a crawler chassis 1-3, a pressing hydraulic device and a pressing mechanism 1-9.

[0058] Engine 1-1, gear pump 1-4, hydraulic check valve 1-5, hydraulic cylinder 1-6, electromagne...

Embodiment 2

[0068] An in-situ chemical injection repair method for soil and groundwater pollution, which was applied to a small polycyclic aromatic hydrocarbon-contaminated site for soil risk control and repair site.

[0069] The pollution depth of the target area is about 3.0m. According to the scope of the target area, a total of 11 injection holes are designed, the design injection depth is 0.5m-1.5m-3.0m, and the design influence radius of a single hole is 1.5m.

[0070] No diving was found in the site. Due to the long history of the site and the backfilling time of more than 10 years, the distribution of soil layers is extremely uneven, and pollutants are distributed in multiple layers. Obviously, the traditional injection construction method cannot achieve the expected restoration goals.

[0071] Therefore, the in-situ formation detection-in-situ drug injection method is chosen, which is realized by the integrated restoration drug injection device of the present invention, which incl...

Description

technical field [0001] The invention relates to an in-situ medicament injection method used in the field of contaminated site restoration, in particular to an in-situ medicament injection repair method for soil and groundwater pollution. Background technique [0002] Soil and groundwater are important environmental media and an important material basis for human production and life. The process of rapid economic development is also accompanied by pollution problems such as industrial chemical leakage and excessive use of agricultural chemicals, which have caused the deterioration of the soil and groundwater environment. In order to reduce human health risks and avoid damage to the ecological environment, it is necessary to use appropriate technical means to remediate and restore polluted soil and groundwater. [0003] The in-situ injection restoration of soil and groundwater can achieve the purpose of restoration by injecting remediation agents into soil or groundwater cont...
