Beijing Zhonghua Zhujian Technology Co., Ltd. is a specialized engineering company engaged in reinforced concrete cutting, demolition, rebar reinforcement, and concrete drilling.
One, concrete cutting and demolition, bridge cutting and demolition, support beam cutting, bearing cutting, reinforced concrete wall cutting and demolition, large beam cutting and demolition of concrete structures, building renovation cutting and demolition, floor and ground cutting and demolition, building demolition construction, static concrete cutting, door and window alteration construction, concrete column cutting and demolition, static cutting and demolition of irregular reinforced concrete structures,绳锯cutting of columns, piers, bridge decks, and road surface cutting and demolition projects, etc.
Underwater concrete cutting and removal services include cutting bridges, docks, reservoirs, ports, underwater cutting, underwater bridge pier cutting, underwater retaining wall cutting, irregular large-section building cutting, reinforced concrete foundation cutting, and elevated bridge reconstruction. Our underwater concrete cutting and removal services are not restricted by construction site, schedule, or safety conditions, breaking away from traditional methods such as jackhammer removal followed by gas cutting or directional blasting. They offer advantages such as minimal impact on surrounding traffic, short project duration, and high safety coefficients.
Three, Reinforcement Grouting, Chemical Anchors, Pre-embedded Bolts, Reinforcement Grouting for Building Structures, Chemical Anchors. It involves embedding steel bars and pre-embedded bonded steel bars into the existing concrete structure to reinforce buildings or for retrofitting. This process includes drilling holes in the original building, inserting steel bars, and then injecting epoxy building reinforcement grout to anchor the steel bars. The steel becomes one with the concrete, achieving a unified load-bearing effect. It boasts high load-bearing capacity, does not cause expansion damage to the base material, is easy to construct, and has a short construction period, among other advantages.
Four: Drilling engineering, drilling cutting engineering, bridge drilling engineering, highway pavement drilling engineering, building drilling, large concrete hole drilling, deep hole drilling, solving various difficult holes in technology. Precise dimensions, high construction accuracy, vibration-free, noise-free, dust-free, in compliance with environmental protection requirements, no damage to surrounding structures and no need for repair. Compact equipment with flexible use, wide application range, using diamond drilling machines and cutting equipment.
