Heavy railThe cross-section is larger than that of light rail and can withstand greater forces. It is applied in different industries. For example, it can be seen in regional railways, intercity railways, urban railways, and urban rapid transit. Now, let's discuss some points to pay attention to during heavy rail construction.

Heavy rail can withstand greater forces. In the early days of mainline railways, 78 kg rails were used, but now 60 kg and 75 kg rails are used. Of course, it also has certain advantages during use. For example, this product differs from light rail in that it is a track for heavy vehicles, not referring to the weight of the track itself. When installing, it is important to check the axis of the concrete foundation and the elevation of the foundation surface. The method of segmental hoisting is used here, first hoisting all H-shaped steel columns. Once this work is completed, heavy rails can be hoisted in sequence after correction and fixation of the grouting, adjusting as they are hoisted, and then proceeding with the installation and fixing of the roof supports and purlin system. In addition to these points, it is also important to ensure the accurate positioning of anchor bolts. It is recommended that workers use steel template holes to fix the anchor bolts. After this is completed, you need to repeatedly check for accuracy before proceeding with the concrete pouring. The part of the anchor bolts exposed above the ground should be wrapped and protected with plastic cloth.

Therefore, the construction method of heavy rail is quite important. In addition to what we have mentioned, it is also important to note that after the column verification is completed, the steel beam hoisting should be done using a two-point symmetrical binding method for installation. When the steel beam is lifted to 100 mm from the column reference surface, it should be slowly positioned. Once this is done, you need to adjust and correct the connection after the steel beam is in place. During the hoisting of the steel beam, use a theodolite for correction, and correct any deviations immediately. The verticality of the heavy rail should be checked with a theodolite or plumb line. If there is a deviation, it is recommended to use a jack for correction at this time. A key point is to use the jack to slightly lift the base for accurate calibration, then adjust the thickness of the pads. Once the column foot is correctly calibrated, immediately tighten the anchor bolts. Therefore, construction personnel must pour fine stone concrete under the column foot base after ensuring the overall calibration of the steel column is correct.
