Recently, following review by the China Exploration and Design Association, two projects undertaken by our company—namely, the geological exploration for the Liugang River Supermajor Bridge on the Xifeng to Qianxi section of the Jiangkou to Duge Expressway in Guizhou Province, and the detailed design for the Longjiayan Landslide Treatment Project in Section No. 2 of the Yanhe to Dejiang Expressway in Guizhou Province—have been awarded. 2019 Second Prize in the Annual Outstanding Engineering Survey and Geotechnical Category; the geological survey project for the Sancha River Supermajor Bridge on the Guizhou section—between Qingzhen and Zhijin—of the Xiamen-Chengdu Expressway received the Third Prize in the Outstanding Engineering Survey and Geotechnical Category.

The geological investigation for the Liugang River Supermajor Bridge on the Xifeng to Qianxi section of the Jiangkou to Duge Expressway in Guizhou Province—a project that won an award—was conducted by our company’s personnel, who, based on the specific characteristics of the project, provided a sound engineering geological assessment of particular engineering issues and proposed appropriate engineering measures. The project was... 2014 Year 7 Construction commenced in the month, and the excavation work revealed that the actual geological conditions matched the investigation data provided by the survey and design unit, providing excellent guidance for the construction process.

Construction Drawing Design for the Landslide Treatment Project at Longjiayan, Section 2 of the Yanhe to Dejiang Expressway in Guizhou Province , The project is located at the Longjiayan landslide along Section 2 of the Yanhe to Dejiang Expressway in Guizhou Province. The landslide has significant thickness and complex geological conditions, resulting in high costs and great difficulty for remediation works. The hidden nature of geological information makes it challenging to conduct comprehensive and accurate analyses and evaluations of the landslide. Our company’s technical staff appropriately adjusted the design方案 for this project, thereby reducing construction difficulties. While ensuring effective landslide stabilization, we managed to shorten the construction period and lower the project costs, achieving excellent socio-economic benefits.

Geological investigation for the Sanchahe Super Bridge on the Qingzhen-Zhijin section of the Xiamen-Chengdu Expressway in Guizhou Province. The highway section from Qingzhen to Zhijin on the Xiamen-Chengdu Expressway in Guizhou Province is constructed to four-lane expressway standards, with a subgrade width of... 24.50m , the design driving speed is 80km/h/ The layout of the route scheme and the selection of bridge locations are the key challenges and critical points of the Qingzhi Expressway. During the preliminary survey stage, particular attention was paid to the Sancha River section. 4 The routes and bridge locations were surveyed with the same level of accuracy. At the same time, horizontal and vertical comparisons were conducted between the route and bridge location alternatives to identify the recommended option. K Line and bridge location; detailed investigation stage for K A detailed engineering geological survey was conducted at the bridge and culvert site. The rock masses and the mined-out areas of bauxite deposits were analyzed and studied, and treatment recommendations were proposed. During the construction phase, the recommended treatments were implemented. Since the bridge was completed, the site has remained stable, and the bridge has been operating smoothly.
