On the basis of on-site identification by the person in charge of Sanjie Company, reporter Wang Wenzhi, and with the cooperation of professionals, the reporter from Economic Reference Daily extensively consulted the geological survey maps, construction design drawings, subcontracting quantity confirmation forms, concrete quantity settlement forms of the relevant roadbed sections of the Lairong high-speed railway, and calculated the actual quantity of the project based on the actual concrete consumption.
(hereinafter referred to as “Sanjie Company”) reported in real name that the construction general contractor China Construction Eighth Engineering Bureau Co., Ltd.
(hereinafter referred to as “China Construction Eighth Engineering Bureau”) is suspected of stealing work and reducing materials.
The Lairong high-speed railway section under construction by China Construction Eighth Bureau.
The general contracting unit for the construction of the third section of the high-speed rail project is China Construction Eighth Bureau, and Sanjie Company is one of the labor subcontractors for this section, responsible for the drilling construction of foundation piles in some roadbed sections.
According to relevant experts, the construction process of threaded piles is to stop drilling after the drilling depth reaches the design requirements, and then lift the drilling pump to pour concrete
.
Construction began in November 2020, and it is expected to have operational conditions by the end of October 2023.
Recently, the labor subcontractor of Shandong Lairong High Speed Railway Section 3 and Henan Sanjie Industrial Co., Ltd.
The results were basically consistent with the problem of cutting corners and materials reported by the reporter.
The Lairong High Speed Railway is a major project in Shandong Province.
More than half of the length of threaded piles in some roadbed sections has severely shrunk.
Xiao Weiguo, the person in charge of Sanjie Company, revealed to reporters that the threaded pile project (with a design pile length of 14.5 meters or 15.5 meters) for the DK128+700-128+925 roadbed section of the Lairong high-speed railway undertaken by him was not constructed according to the drawings.
The roadbed is an important component of the high-speed railway line, and its stability directly affects the quality of the line, normal train operation, and safety.
In addition, other labor subcontractors responsible for the third section of the Lairong high-speed railway have reported similar issues during the pile driving construction process of the roadbed section they constructed.
There are quality issues in the construction of threaded piles in some roadbed sections of the Lairong High Speed Railway, and the construction pile length of most of the threaded piles in this section does not meet the design requirements, There are significant safety hazards.
The line starts from Laixi City, Qingdao in the west and ends in Rongcheng City, Weihai in the east, with a total length of 193 kilometers, a total investment of 29.7 billion yuan, and a design speed of 350 kilometers per hour.
Real name reporting by construction personnel! The Shandong Lairong High Speed Railway has hidden significant safety hazards due to cutting corners and materials.
The actual construction pile length was mostly 10 to 13 meters, and more than 90% of the threaded piles did not reach the design length; During the construction of the railway track subgrade at the Nanhai Station of the Lairong High Speed Railway (DK147+412-DK147+950), most of the threaded piles did not reach the designed pile length.
