Recently, the field survey team has gradually carried out the first batch of key soil site survey projects in 2020. The first batch of site survey projects include the Shanwei tunnel fracture zone project, the project of heavy metal waste landfill, and the Shenzhen radar road inspection project. The second batch of projects is also closely following After that, it will be launched soon

After more than two months of the nationwide anti-epidemic war, under the unified prevention and control of the whole country, we have achieved phased victory. From the cold and steep winter, we finally look forward to the arrival of spring in bloom. All parts of the country have begun to resume work. The Shenzhen and Wuhan offices of Geomative strictly abide by the "Guidelines for the Prevention and Control of Epidemic Prevention and Control Measures for the Resumption of Work and Production of Enterprises and Institutions" issued by the State Council to strengthen employee health monitoring, prevent and control workplaces, and guide employees' personal protection requirements. Disinfect the office in time intervals, monitor the body temperature in real time, and have sufficient protective materials, and formally resume work in an all-round way.

Recently, the field survey team has gradually carried out the first batch of key soil site survey projects in 2020, and the second batch of projects will soon follow. Under the influence of the severe epidemic, even if the field survey team is faced with the challenge of tight schedule and heavy workload, it has always been on the spot, stationed at the scene, and carried out various projects in an orderly manner. At the same time, the production department is also speeding up the production schedule, and the production target task is 2-3 times that of the same period last year. After the resumption of work, the entire Geomative team has stabilized production, and the work is on the right track. All projects are carried out simultaneously and the firepower is fully launched.

Shanwei Tunnel Fracture Zone Project

Undertake the tunnel exploration project of Guangzhou Transportation Planning and Design Institute, the site is in Shanwei, Guangdong. The main purpose is to detect a new tunnel through the mountain planned by Haifeng to Honghai Bay. The length of the tunnel is about 2500m. This project uses the ERT method to detect the geological structure of the mountain above the tunnel and the location of the cavity or fracture zone. The entire detection depth range is 50-240m, and the test uses 8m spacing and 120 ERT measuring lines. The rolling method is used for measurement, and the drilling sampling results are used to evaluate the depth and range of the surrounding rock and rock and soil overburden. Provide a favorable reference basis for the final construction plan. Ensure that there is no repeatability of measuring points, and increase the test area, and the test efficiency is high.

Landfill project of heavy metal waste

There is residual waste slag underground in a chemical plant. To prevent the chromium slag from seeping out, the ground was covered with cement due to historical reasons to investigate the depth and thickness of chromium slag landfill. GD-20 multi-channel equipment is used to avoid damage caused by rotating sampling. On the cement floor of the survey plant, 3 measuring lines are arranged with a total length of 300 meters and a sounding depth of 10 meters. It can penetrate without large-area drilling and sampling. A wide range of measurements are used to obtain continuous profile data, with low construction costs, preventing further diffusion of pollution, environmental protection, and no secondary pollution.

Shenzhen radar road detection

With the rapid development of urban construction, the functions of urban roads have become complicated, the traffic volume has increased sharply, the load on the lanes has increased, and the complicated municipal pipelines laid in the road structure layer have caused an increase in urban road diseases. Especially in the past five years, urban roads have collapsed. Gradually entering the peak period of concentrated outbreaks of disasters across the country, it has plagued the first-tier, second-tier, and third-tier large, medium and small cities, causing huge loss of life and property and social impact. The ground vein field survey team was commissioned by the government as the first key project 3D geological radar visual geophysical exploration, and the urban road disease detection project was proceeding as scheduled.

Geomative has mastered physical prospecting technology and rich experience in field surveying for many years. It has carried out multiple site survey projects simultaneously, and successfully completed the acceptance and delivery. Although the start of 2020 is difficult, I hope that the obstacles in the first half of the year will be surprises for the second half of the year. With professional geophysical technology and years of site survey service experience, we have reached business cooperation with government units and enterprises to overcome the difficulties together. Participate in soil pollution investigation, disease risk assessment and other projects, shoulder the mission of environmental protection of the earth, and take the path of sustainable development.
