[0002] As the urbanization process accelerates, residents' pursuit of quality of life continues to improve. Faced with the problems of overcapacity and tight urban living land, urban development strategies are undergoing a transformation, that is, from "de-industrialization" and "re-urbanization" dominated by heavy industry to "de-industrialization" and "re-urbanization" with a focus on the service industry. In this transformation process, a large amount of original industrial land has been idle and become industrial brownfields. How to effectively renew these industrial heritages is not only related to the improvement of the city's appearance, but also an important way to promote social prosperity.

[0003] Roof insulation renovation plays a pivotal role in improving the indoor thermal environment of old factories. The original roof of this project had no insulation measures. By adding 85mm thick polystyrene boards as thermal insulation materials on the roof layer, and setting a waterproof coating layer under the insulation layer, and laying modified asphalt waterproof membranes with waterproof protective layers on the insulation layer to form an inverted roof, condensation water is avoided in the insulation layer due to the temperature difference between the inside and outside, so that the insulation layer is protected and the service life of the roof is extended. This method retains the original appearance of the ceiling inside the factory to a great extent.

[0004] In view of the high risk of secondary pollution in soil remediation projects and the delay in discovering problems through post-event and regular testing, a digital online supervision system is established to standardize the construction and management of online monitoring systems for pollution emissions from on-site construction, online monitoring systems for electrical signals of pollution control equipment, positioning monitoring systems for vehicles transporting contaminated soil, and video monitoring systems, so as to strengthen the risk management of soil pollution in construction land and the prevention and control of secondary pollution in remediation projects.

When there are abnormal situations on the vehicle's driving route, the system has the function of notifying abnormal matters.

[0040] When a short-distance truck carrying contaminated soil in a contaminated soil site enters a nearby white area, the system should notify the user of the abnormality.

[0041] Video online monitoring module (1) Hardware requirements The resolution of on-site fixed shooting instruments shall not be less than 4 million pixels. The design and installation of the monitoring system may refer to JGJ / T292-2012.

[0042] The photo formats can be .JPG, .TIFF, .BMP, and the video formats can be .AVI, .MPEG, .WMV and other common formats.

There should be no blind spots in the monitoring areas, and the video information should be able to feedback the key components / key process links of the construction equipment, such as personnel operation, equipment operation, and material entry and exit.

[0045] For polluted land of more than 400 mu, the restoration construction site should be monitored in full view. It is recommended to conduct high-altitude panoramic video recording at a frequency of once a week, and the relevant images can be accessed in the system.

[0046] It also includes the online supervision through the OA approval process, which is not the focus of this application, but for the sake of technical completeness, the following explains the division of responsibilities for office implementation and the division of labor for online supervision: Construction unit Responsible for organizing system construction, updating, and maintenance, and implementing solutions to abnormal problems such as excessive on-site online data, pollution control facilities, and vehicles discovered by regulatory authorities.

[0047] The construction unit should purchase relevant monitoring (control) equipment, debug it, complete the work of connecting signals and data to the system before construction, and submit it to the supervision unit for verification; carry out daily maintenance and calibration of online monitoring equipment during construction. Make offline rectifications and feedback the rectification results for the problems reported by the online supervision system. Regularly report and upload data such as the excavation volume, external soil volume, backfill volume, soil remediation project, temporary soil storage volume, and monitoring data files during construction for each foundation pit; before dismantling the hardware of the online monitoring system, report relevant matters to the system operation and maintenance unit.

[0048] The supervision unit shall verify the online monitoring plan for secondary pollution prepared by the construction unit before construction, conduct on-site verification of the availability and commissioning of relevant hardware, and organize relevant training on online supervision of secondary pollution prevention and control for the construction unit and land user; verify the abnormal information of early warning during the construction process, clarify the requirements for on-site rectification work, review the rectification effect of the construction unit, and upload the rectification process data of abnormal events to the system. Regularly carry out online monitoring hardware operation inspections; regularly upload various construction technical data.

[0049] The effect evaluation unit shall carry out interim data reporting of effect evaluation in accordance with the actual progress of the work. The reported information shall include on-site sampling time, personnel, qualified repaired foundation pits, qualified repaired soil volume, unqualified repaired foundation pits and soil information and work video data, and upload the coordinates of the turning points of the qualified foundation pits.

[0050] In principle, the data analysis system for online assessment should conduct data statistics on secondary pollution prevention and control work once a week.

[0051] The main contents of the statistics include: 1) Overview of the operating hours, processing capacity, abnormal operation and downtime of wastewater treatment facilities, waste gas treatment facilities (fog cannons, organized waste gas collection systems and greenhouse fans) and contaminated soil remediation equipment; 2) Online monitoring results of air and noise in four directions at the boundary of the plot, including average emissions of monitoring indicators and emissions exceeding the standard; 3) Statistics on the situation of short-distance trucks entering the white zone and abnormal transportation data of vehicles transporting contaminated soil out of the area; 4) Dangerous operations and illegal operations discovered by video surveillance; 5) Construction units, supervision units and effect evaluation units use the system according to nodes.

[0052] Abnormal situation handling The system makes judgments based on the real-time data from the monitoring module. Abnormal situations are divided into two categories: warning level and rectification level.

[0053] The warning-level abnormal situation is that under the premise that the online monitoring indicators of wastewater and exhaust gas meet the standards, the relevant pollution prevention and control facilities (such as sprinklers, fog cannons, wastewater dosing systems, etc.) are not turned on. At this time, the system should, in principle, send the status of the non-turned equipment to the project supervision unit and the construction unit once / half a day as a reminder. The main content of the reminder is to check the relevant equipment.

[0054] When an abnormal situation at the rectification level occurs, such as when wastewater or exhaust gas online monitoring indicators exceed emission standards, or when pollution transport vehicles deviate from their routes or delivery is overdue, the system will send a text message notification to the construction unit, supervision unit, and construction unit to inform them of the specific exceeding matters.

[0055] The system notifies and urges the supervision and construction units to verify the problems and carry out corresponding rectification. The specific process is as follows: (1) The basic information of abnormal matters will be sent to the construction unit, supervision unit and construction unit via SMS, and the abnormal matters will be scrolled on the system home page.

[0056] (2) After checking the abnormal items (rectification level) in the system, the supervision unit shall confirm the abnormal information transmission on the system, and shall immediately conduct on-site review of the abnormal situation and record the process in detail. If the abnormal items are not caused by poor construction or on-site management (such as inaccurate online equipment, other factors not related to the project, etc.), contact the system administrator to eliminate the warning items.

[0057] (3) For secondary pollution that is indeed caused by poor construction and on-site management, the supervision unit may, based on the on-site situation, require the construction unit to suspend or stop construction and carry out rectification work, and fill in the rectification requirements and rectification deadline in the system.

[0058] (4) After the relevant matters have been rectified, the construction unit shall submit a rectification verification application to the supervision unit. The supervision unit shall conduct acceptance and upload the relevant process data of the abnormal matter to the system within 48 hours after determining that it is qualified, and confirm in the system that the rectification is in place (the abnormal situation has been eliminated).

[0059] (5) If the rectification of abnormal situation exceeds the deadline, the system should, in principle, automatically send reminder information to relevant personnel once a day and continue to scroll the reminder on the system page.

[0060] To achieve the following functions (1) Coverage of risk factor supervision It covers environmental emission factors and environmental risk links, pollutant emissions, operation of pollution control facilities, transportation of contaminated soil, and standardized remediation construction.

[0061] (2) Construction rectification closed loop Establish a full traceability mechanism of "system early warning, supervision review, on-site rectification, online cancellation, and process records".

[0062] (3) Leaving traces of the online supervision process The construction process shall be archived and the indicators for networking with relevant provincial and municipal management systems shall be clearly defined.

[0063] Other map deployments: Using "BIM+AR" technology, recycled materials unique to industrial relics such as rails, sleepers, steel plates, and I-beams are reborn in the form of positioned paving, retaining the rural characteristics of the collision between industry and nature in the heritage site, and achieving the dual goals of cultural inheritance and renewal and development.
