Shaanxi Annwa Construction Engineering Co., Ltd.   

Shaanxi Annwa Construction Co. Ltd. is a strong qualification building reinforcement engineering company, the registered capital of 10 million, the Shaanxi Provincial Department of Construction approved housing construction general contracting and construction industry contracted professional qualifications. At present, the construction and reinforcement of steel structure, crack treatment, building rectification, consulting and design is the core of our business, mainly to provide reinforcement consultation, scheme design, structure identification, reinforcement construction and reinforcement engineering construction materials such as the supply of services for customers. We are willing to take advanced professional technology and management, quality products and services and engineering construction units, design units, the contracting units of sincere cooperation, mutual benefit and common development, create a better future. The company undertake the following business: One, concrete drilling: drilling techniques include horizontal drilling, vertical drilling and high precision deep hole drilling. Diamond drilling technology has the characteristics of economy, safety, environmental protection, no vibration. Scope of application: 1, on the water, fire, cable, air conditioning, ventilation ducts and other installations; buildings, dams, bridges, large-scale facilities and equipment to take core test drilling; 2, dams, bridges, large equipment foundation grouting reinforcement, anchorage heightening drilling; 3, all kinds of fencing and large equipment installation drilling; 4, blast furnace cooling pipe installation drilling; 5, other kinds of high difficulty special drilling and technical advice. Two, concrete static cutting: Including diamond hole cutting, plate cutting and sawing rope saw cutting. The cutting and disc saw cutting technology has the advantages of low cost, high efficiency, good quality, safety and environmental protection, etc., and is suitable for large area cutting of plane concrete structures such as plate and wall. Rope saw cutting technology is cutting the world's most advanced, with cutting speed, smooth cutting surface, wide application range, and has no vibration, low noise, environmental safety, suitable for cutting concrete structure houses, bridges, culverts, concrete columns, beams, plates and all kinds of specific section the. Three, concrete structure reinforcement: Including steel Baotou, sticky carbon cloth, steel wire, bar, steel reinforcement, bonding prestress etc.. 1, stick steel reinforcement is the use of building structure adhesive relay strong, shear tensile strength, steel reinforced concrete is pasted on the surface, to the original structure of reinforced concrete columns and beams, slabs and the reinforcement, in order to improve the bearing capacity of structure, increase the shear strength and seismic behavior and stability, improve the stress state. 2, the carbon fiber cloth reinforcement is the use of carbon fiber cloth, high strength, flexibility, light weight, corrosion resistance and other advantages, to strengthen the concrete structure. The tensile strength is 10 times the weight of steel, 1/60 steel, reinforcing structure after almost no increase in load, and has the characteristics of acid and alkali, does not rust. 3, steel bars and chemical anchors are widely used in building structure by layer, overhanging, new floors, beams and columns of rooting, insertion depth is generally 15d (d bar diameter). The chemical anchor bolt in steel structure anchor anchor bracket installation plays an important role in.
