Railway bridge culvert cutting and demolition can be carried out using hydraulic expansion cracking and破碎demolition methods. This technique allows for the control of construction damage points and ensures safe and effective control and use. It primarily utilizes drill machines for precise drilling, followed by manual injection of expansion agents to cause cracking. Once everything has cracked, the broken concrete blocks are transported to the site using the hydraulic machinery's self-equipped crushing vehicles for disposal. It is important to note that safety must be prioritized when using this construction method.

In the cutting and removal of railway bridge culverts, this method is safe, efficient, and cost-effective. However, it does have limitations, such as limited alteration to the height of the bridge. The specific construction method should be adjusted according to the actual situation. The cutting and removal of railway bridge culverts can be carried out using diamond wire saw static cutting. This method's features include using wire saw software programming to design and layout large pieces of material, enabling vibration-free, shock-free, and low-noise static removal construction. It also effectively controls secondary crushing by manpower, dust removal, and vibrations, ensuring the safety of workers in the work area. It is an environmentally friendly and safe construction method.

The specific cutting and dismantling process may vary depending on the circumstances. It is recommended to consult with an engineer and follow engineering safety regulations.
