An important part of the Jingkun Passage in the main passage 

Xiong’an High-speed Railway starts from Xiong’an Station of Beijing-Xiong Intercity Railway and ends at Xinzhou West Station of Daxi High-speed Railway. It is of great significance to further promote the high-starting planning, high-level construction, and high-quality development of Xiong’an New Area, and better create an innovative development demonstration zone and a world-class city high-end industrial cluster.

The participating project is the XADXDSG-2 bidding section of the underground section of the Xiong’an New District of the Xiongxin High-speed Railway and related supporting projects. , in this bid section, the process test section of TRD cement-soil mixing wall is proposed to be DK120+950 segment compartment, the construction length of TRD cement-soil mixing is 22.4m, the wall thickness is 80mm, the reinforcement depth is 27m, the level elevation of the railway tunnel in the test section is +2m, the current situation The ground elevation is +7m. The project requires that the plane deviation of the wall position should be less than 25mm, the vertical deviation should not be greater than 1/250, and the wall depth, wall thickness, and total length of the wall should not have any negative deviation.

According to the geological data around the site, the site is mainly the Baigou diversion river (part of the channel adjacent to the tunnel is buried by wasteland, farmland and green belts), and the geological conditions are complex. The SEMW TRD-70E construction machine has excellent performance, stability and precision, and can quickly adapt to construction. Environment, with the excellent construction performance of the advanced excavation speed of 2m/h, the withdrawal excavation speed of 8m/h, and the wall-forming stirring speed of 2.4m/h, the first show of the test pile was completed, and the test was completed excellently.

During the construction process, in order to maintain the horizontality of the chassis of the TRD construction method pile driver and the verticality of the guide rod, the inclinometer installed inside the cutting box is used to manage the vertical accuracy of the wall during construction. The verticality of the wall is not greater than 1/ 250, to ensure the quality of the wall.

Facing the difficult situation of rushing to work on the construction site and “working in three shifts without stopping”, the SEMW TRD-70E construction machine has zero failures and high efficiency, overcoming many difficulties such as tight construction schedules, heavy tasks, and site restrictions. Hunan Chengji Work hand in hand with “SEMW Green” to realize the smooth progress of the construction of the Xiongxin high-speed railway. 

In addition, it is worth mentioning that within a few kilometers near the XADXDSG-2 bid section of the project construction site, 4 SEMW TRD series construction machines have been stationed in each construction unit, and more TRD construction machine equipment will be stationed in the later period. After the “Major Ecological and People’s Livelihood Project of Ganjiang River” and “Pudong Airport Underground Transportation Hub Project”, SEMW TRD series equipment gathered again for a big construction scene. At that time, there will once again be SEMW green figures all over the venue, fully demonstrating the responsibility and responsibility of SEMW in helping the construction of Xiong’an New District, and demonstrating the century-old SEMW national brand style.

Hunan Chengji Construction Engineering Co., Ltd., the construction unit participating in the Xiongxin high-speed railway project, is the first enterprise in Hunan Province to have TRD engineering equipment. The company is mainly engaged in foundation foundations, municipal roads, deep foundation pit excavation and support and A modern construction enterprise for urban underground utility corridors. Possess a number of professional construction qualifications such as “Grade 1 Professional Contracting of Foundation and Foundation Engineering”, “Grade 3 General Contracting of Municipal Public Works”, “Grade 3 General Contracting of Highway Engineering Construction” and “Construction Labor Service”, mainly with rotary drilling and impact drilling There are more than 60 sets of large and medium-sized mechanical equipment such as reverse circulation drilling rigs, hydraulic down-the-hole drilling rigs, three-axis mixing pile machines, ground-wall grooving machines, road rollers, paver machines, and 5000-type asphalt mixing plants.
