Description

Technical Field

[0001] This invention belongs to the field of reinforced concrete demolition technology, specifically a method for demolishing adjacent diaphragm walls and a static cutting wire saw. Background Technology

[0002] Diaphragm walls are continuous underground walls formed by excavating narrow and deep trenches in the designed ground using various trenching machines and with the help of mud slurry for wall protection. They are filled with appropriate materials to form a continuous underground wall with functions of seepage prevention, soil retention and load-bearing. Diaphragm walls have high rigidity, high load-bearing capacity and good seepage prevention performance. They can be used for reverse construction and are gradually replacing many traditional construction methods in various foundation projects.

[0003] In transportation hubs with large spans, construction needs to be carried out in phases to shorten the construction period. The retaining structure used to separate the construction sequences is a diaphragm wall. The existing structure is a two-story open-cut structure that was completed in the early stage. In order to connect the existing structure with the later structure, the 1.2m thick and 5m wide diaphragm walls on both sides of the already stabilized existing structure need to be demolished before the later cut-and-cover structure is constructed.

[0004] When demolishing diaphragm walls, it is necessary to ensure that adjacent existing structures do not deform and that beams and slabs are not damaged by demolition debris. However, existing mechanical demolition methods cause significant disturbance, noise, and dust pollution to existing structures, which can easily lead to deformation and damage.
