Support Removal, Bridge Demolition, Concrete Support Cutting - What are the Methods for Support Beam Removal? "Qingpeng Construction" provides a detailed explanation of the foundation support beam removal process.
Support beam removal methods typically include blasting, mechanical demolition, manual dismantling, static blasting, and wire saw cutting.
Various Demolition Methods - Features:
(1) Blasting Demolition: Instant release of explosive pressure, short construction period, suitable for overall demolition of buildings in open areas. However, in busy city districts and densely populated areas, it causes significant vibrations, which have a considerable impact on existing structures, surrounding buildings, and underground facilities. It also poses a risk of flying debris to pedestrians on the streets. Not applicable for removing support beams in foundation pits, and it is expensive.
(2) Mechanical Demolition: Utilizes explosive machines for demolition, which results in significant vibration, noise, and dust. Not suitable for construction in urban areas, residential neighborhoods, or along subway lines, and渣土清理 takes a long time.
(3) Manual Demolition: Manual jackhammer demolition offers high safety but is time-consuming, also noisy, and generates a lot of dust. It is only suitable for small-scale projects.
(4) Static Explosive Demolition: Utilizes static expansion agents for a quiet, non-vibrating demolition that gradually transfers force to the concrete supports, causing them to fracture. This method is safe, with no flying debris, low noise, but it is time-consuming and the construction process is slow.
(5) Wire Saw Cutting Demolition: Utilizes static rope sawing to cut support beams into segments, which are then lifted out by cranes, loaded onto trucks for transportation to the site, and crushed for waste recycling. Compliant with environmental protection standards, it offers no vibration, noise, dust, or pollution, with a short project timeline and fast execution. It is the most widely used and general demolition method currently available.

Support Beam Cutting Process: Set up bottom support for the beam → Mark cutting sections → Mechanical equipment arrives for electricity and water supply → Cut and section support beam, girder construction → Forklifts, cranes, and waste mud trucks arrive for transport (or on-site crushing), and shipment of concrete blocks → Concrete blocks crushed by oil炮 machine → Steel recycling → Site cleanup
Structural Column Treatment: Structural column removal is conducted after the basement structure is completed. Segmentation cutting is performed on the bottom and top surfaces of each floor using oxygen welding, followed by transportation to the site using forklifts via the access lane.

With the development and construction of cities, land in urban areas is becoming increasingly scarce. As engineering projects require deeper excavation for basements, the support beams for pit support are inevitably installed to ensure the safety of the pit and its surroundings. During the construction of the basement structure, the support beams must be removed before proceeding to the next stage. The speed of removing these beams directly impacts the progress of the project and may lead to issues such as worker downtime.
