Description
Technical Field
The invention relates to a device used in the field of contaminated site remediation, in particular to a refined remediation medicament injection device based on contaminated land stratum characteristics.
Background
Soil and groundwater are important environmental media and are important material bases for human production and life. The rapid development of economy is accompanied by the pollution problems of industrial chemical leakage, excessive use of agricultural chemicals and the like, and causes the deterioration of soil and underground water environment. In order to reduce the risk of human health and avoid the damage of ecological environment, the polluted soil and underground water must be treated and restored by proper technical means.
The in-situ injection remediation of the soil and the underground water is realized by injecting remediation agents into the polluted area of the soil or the underground water to convert pollutants in the soil or the underground water into substances which are nontoxic or have relatively low toxicity, thereby achieving the purpose of remediation. In situ remediation agent injection is typically performed by injection well injection or by direct push injection via an injection rod. The injection well type injection directly injects the repairing agent into a pre-established injection well, and utilizes stratum fractures and underground water to flow and convey the repairing agent. The injection rod direct-push type injection is that after the injection rod with an injection head is pressed down to a target stratum, the peripheral stratum is split through high pressure to form a local fracture for quickly conveying the medicament, meanwhile, the dispersed medicament can further diffuse through the flow of underground water, and the injected medicament can fully contact with pollutants in a certain range. When the heterogeneity of the polluted land stratum is stronger or the repairing agent with slurry state and larger viscosity is injected, the injection rod is generally used for direct pushing type injection.
The injection rod direct-pushing type repairing medicament injection device is generally composed of a medicament stirring barrel, an injection pump, an injection rod pressing device, an injection rod, an injection head and the like which are separated from each other on the ground, all devices are generally assembled and connected manually, the integration level is poor, the devices are required to be moved and reassembled respectively when an injection area is replaced, the whole mobility and flexibility are poor, and the repairing project with short construction period cannot be served.
In the implementation of a repair project adopting a direct-push type medicament injection process, injection construction parameters such as injection volume, injection pressure flow and the like are designed and determined mainly based on site general parameters determined by a geological survey result of a previous project at present, the injection construction parameters are limited by the precision of geological survey, the design is very easily influenced by local stratum heterogeneity, the problem that the injection design parameters unified in the whole field are not matched with the actual stratum condition in a small range occurs, slurry leakage and short flow during site injection construction are caused, the medicament is wasted or secondary pollution is caused, the problems that the local medicament injection amount is insufficient and the repair effect is difficult to guarantee are caused, and the overall repair efficiency is poor. In addition, the mode of pushing down of injection pole in the injection process of medicament at present mainly adopts the vibration knocking type to push down, causes horizontal disturbance easily in the process of pushing down and makes and produces the gap between injection pole and the peripheral soil layer, is changeed and is caused the grout emitting problem when injecting the construction.
Static sounding can effectively determine soil layer vertical distribution and soil layer engineering geological parameters on a single point position as an in-situ geological detection technology, a detection probe adopts a hydraulic pressing mode, equipment runs stably, and the device is more suitable for soil types compared with other in-situ detection technologies, so that the characteristics of the technology can be considered for reference to improve a repairing agent injection device.
