"Shenwan no. 1" shield machine of Suiguanshen Project passed through T3 terminal successfully

On October 3, guangzhou guan deep inter-city rail transit I mark a work area "deep bay of shield machine to complete one" through the T3 terminal duty dormitory building (hereinafter referred to as "T3 dormitory building"), marked the first time deep iron cast hazards of shield of the building through the successful completion of the assignment, shield tunneling process through the structure construction quality and safety of double control target tested.

In order to ensure the T3 dormitory building smoothly through, project in the construction of special solutions discussed for many times, and invited, including group co., LTD. Shield, chief expert of experts under the shield in tunneling construction review detailed argument, replace tool, inspect refurbished equipment in advance at the same time, to ensure the safety of shield machine fast, continuous and complete wear under construction.

The project department has established a 24-hour seamless linkage leadership duty system, fully equipped with construction auxiliary equipment and material reserves. From September 17 to October 3, the shield tunneling of 471 rings completely passed through the influence area of the dormitory building, with a total of 163.8 meters of tunneling in 16 days, with an average daily footage of about 10 meters. Monitoring data show that the cumulative maximum deformation is +1.27mm, which achieves the construction target of safe and rapid underpass.

Through the successful construction of "Shenwan No.1" going through T3 on-duty dormitory building, the project department further summarized the construction technology and management experience, optimized the tunneling parameters of shield tunneling risk project, and provided significant guidance for the smooth construction of subsequent risk projects such as shield tunneling through Xiwan sea area with long distance complex strata.

Next, the project department will continue to improve and improve the construction management ability of the project, improve the management level, establish safety awareness, and make unremitting efforts to promote the rapid and steady construction of Suizhou, Dongguan and Shenzhen intercity.

Starting from shenzhen Airport Station and ending at Qianhai Station, the line reaches Qianhai comprehensive transportation hub via Hangcheng, Xixiang and Xin 'an Streets in Bao 'an District, with a total length of about 15.2 kilometers. It is divided into two sections for construction successively. After the completion of the front section of the Suiguan-Shenzhen-Guangzhou Intercity Airport project, it will be able to interconnect with the established Suiguan-Shenzhen-Guangzhou and pazhou Branch Line, Fo-Guan, Dongguan-Huizhou and other intercity areas under construction, so as to realize fast access between Guangzhou, Dongguan, western Shenzhen and the central urban area of Shenzhen as well as important areas along the line.
