Problems solved by technology
[0004] In the current in-situ injection technology, the connection and sealing of the injection equipment and the injection well are mainly sealed and fixed by concrete sealing, glue sealing and hot-melt method, etc. Such methods cannot be flexibly disassembled or replaced; the single-port flange sealing and fixing method, It only has the function of injecting medicaments, and cannot quickly connect and replace pipes, and cannot collect samples and monitor in real time to understand the operation of the injection well, and lacks efficient operation of the system

Abstract
The invention discloses an application method of a connection and sealing device. The connection and sealing device is used for automatic injection sampling monitoring of soil and groundwater restoration. The connection and sealing device is installed at the wellhead of an injection well and connected to an injection hose corresponding to an injection pump. , can inject water or drug solution in the injection pump into the injection well, and can monitor and control the injection pressure and flow in real time; the connection sealing device can disconnect the connection port of the injection hose at any time, and can realize the connection and sealing of different injection wells The device can be freely combined with different injection pumps and can be used repeatedly; when the monitoring equipment needs to collect groundwater samples, the connection sealing device does not need to be disassembled, and the groundwater samples can be directly and quickly collected into the corresponding container, and the corresponding indicators can be automatically monitored online in real time. It is used to automate the setting and operation of injection parameters, so that the system can effectively improve work efficiency.
Description
technical field [0001] The invention relates to an application method of a connection sealing device, which belongs to the technical field of soil and groundwater restoration. Background technique [0002] At present, the overall situation of soil environmental pollution in my country is relatively serious. On August 31, 2018, the Fifth Session of the Standing Committee of the Thirteenth National People's Congress unanimously passed the Soil Pollution Prevention and Control Law, marking a milestone in my country's soil governance and the legal obligation of soil environmental protection and governance. [0003] my country's soil remediation technology is still in its infancy, among which soil in situ remediation technology is a newly emerging soil remediation technology in my country, and in situ injection technology is relatively widely used in soil in situ remediation technology. In-situ injection technology is to inject water or agents into soil and groundwater through c...
