Shaanxi Annwa Construction Engineering Co., Ltd.   

Shaanxi Province China Construction Engineering Co., Ltd. is a strong qualification of building reinforcement engineering company, the registered capital of 10 million, approved by the Shaanxi Provincial Department of construction, housing construction general contracting and construction industry professional contracting qualification. Currently reinforcement structure, transformation of the construction, steel structure, crack treatment, building correction, consulting and design is our core business, mainly to provide customers with consulting reinforcement, design scheme, structure identification, strengthening construction and reinforcement engineering construction material supply etc. all kinds of services. 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. Wire saw cutting technology is currently the world's most advanced cutting technology, with cutting speed, smooth cutting surface, wide application range and other advantages and has no vibration, low noise, environmental protection and other safety features, applicable in cutting bridges, housing, culverts, concrete column, beam, plate and various specific section of concrete structure. Three, concrete structure reinforcement: Including steel Baotou, sticky carbon cloth, steel wire, bar, steel reinforcement, bonding prestress etc.. 1, bonding steel plate reinforcement is the building structure adhesive relay is strong, the shear tensile strength characteristics, pasting steel plate on the surface of the reinforced concrete, has reached to reinforce the original reinforced concrete frame columns, beams, slabs and the mouth of the cave, in order to improve the structure of the bearing capacity of the, increase 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 higher than that of iron and steel, weight 1 / 60 of the iron and steel, reinforcement after almost no increase in structural load, and has acid and alkali resistance, no rust. 3, planting and chemical anchor bolt is widely used in building structure to add layer, cantilevered, newly added floors, beams, columns, and other basic rooting and depth of the implant is generally 15 days (D is the diameter of the reinforcing bar). The chemical anchor bolt in steel structure anchor anchor bracket installation plays an important role in.
