Recently, the "Pier Sites Automatic Spraying Conservation" system for the innovation of the Shenbai High -speed Railway Project of China Railway 15th Bureau has become a landscape at the construction site. The system only needs manual intervention when installing and promoting, and increases the area of ​​concrete flowing water in the pier body, which not only avoids the "thick water column and small area" of artificial water pipe maintenance, but also guarantees the quality of the concrete entities. Reduce water consumption.

The company is responsible for the construction of the Shenbai high-speed rail Jilin section TJ-4 standard for a total length of 30.651 kilometers. The project is located in the severe cold area of ​​high latitudes. The effective construction period of the year is short, and the intense construction period puts forward higher requirements for the quality of the project. Since the start of construction, the project department has always regarded scientific and technological innovation as a powerful means to improve the quality of the project, starting from a small department to "empower" technological innovation measures as quality management work. To this end, the project department specially set up the "Li Panfeng Modeling Innovation Studio" and set up a science and technology research team to provide a strong support for solving the problems encountered in the construction.

Their tunnel two lined softening small innovation results can effectively protect the edge of the concrete not squeezed by the two -lined buildings, ensuring the appearance and physical quality of the exterior between the two -sets of the tunnel. In addition, the two -lining soft overlap adopts a medium -buried water -stopd stuck card steel -end mold, which is fixed with a U -shaped steel bar and a distance of 50 cm. It can effectively avoid the occurrence of water stops and cutting concrete in the process of concrete pouring. Effect.

During the construction, "ingenuity" everywhere has become a habit of members of the key group. Change the original tunnel's upper arches of straight -angle three -way drain pipe connector to 135 degrees of different types. A small change not only effectively reduces the construction time, but also makes the quality of the connection of the three -way drainage pipes more guaranteed; the tunnel insulation board The invention of a dedicated buckle reduces the procedure of the padding and connection bands as a medium. It is better to ensure the fixed quality installation of the thermal insulation board. After the on -site test, the joint seam between the thermal insulation board is closer than the connection band process, and the gap is smaller. Based on the micro -innovation of science and technology, the construction of the Shenbai high -speed rail is safe, green and efficient.
