Shaanxi Annwa Construction Engineering Co., Ltd.   

Shaanxi Annwa Construction Engineering Co., Ltd. is a strong building reinforcement engineering company, with a registered capital of 10 million, approved by the Shaanxi provincial construction department for building construction general contracting and special industry professional contract qualification. At present, structural reinforcement, reconstruction, steel structure, crack treatment, building rectification, consultation and design are our core businesses. We mainly provide customers with all kinds of services such as reinforcement consultation, scheme design, structural identification, reinforcement and reinforcement, construction materials supply and so on. We are willing to cooperate with engineering construction units, design units and contractors with advanced professional technology and management, quality products and services to create a better future with mutual benefit and common development. Our company undertakes the following businesses: 1. Concrete drilling: drilling technology includes horizontal drilling, vertical drilling and high precision deep hole drilling. The drilling technology of water hammer has the characteristics of economy, safety, environmental protection and no vibration. Scope of application: 1, water, fire, cable, air conditioning, ventilation pipe installation; building, dams, bridges, large-scale equipment and equipment core drilling holes; 2, dams, bridges, large-scale facilities and equipment foundation grouting reinforcement, planting reinforcement to increase drilling; 3, all kinds of guardrails and installation of large facilities and equipment drilling; 4, blast furnace cooling pipe installation boreholes; 5, all kinds of high difficulty special drilling and technical advice. (two) concrete static cutting: it includes cutting, cutting, sawing and sawing. The technology of cutting holes and sawing saws has the characteristics of low cost, high efficiency, good quality, safety, environmental protection and no vibration, etc., and is suitable for large area cutting of plane concrete structures such as boards and walls. The rope saw cutting technology is the most advanced cutting technology in the world. It has the advantages of fast cutting speed, smooth cutting surface and wide application scope, and has the characteristics of no vibration, low noise, environmental protection and safety. It is suitable for cutting bridges, houses, culverts, concrete columns, beams, boards and various concrete structures with different cross sections. Three. Concrete structure reinforcement: it includes clad steel clad steel, sticky carbon cloth, planting bar, steel strand, unbonded prestressed reinforcement, steel reinforcement, etc. 1, glued steel plate reinforcement is the use of the building structure sticky relay strong, shear and tensile strength of the characteristics, the steel plate pasted on the reinforced concrete surface, has reached the original reinforced concrete column, beam, floor and portal reinforcement, in order to improve the bearing capacity of the structure, increase shear resistance, seismic and stability, improve the stress state. 2 and carbon fiber reinforced concrete are used to reinforce the concrete structure with the advantages of high strength, large elasticity, light weight and corrosion resistance. Its tensile strength is 10 times that of iron and steel, and its weight is 1/60 of steel. After reinforcement and reinforcement, it hardly increases the load of structure, and has the characteristics of acid resistance, alkali resistance and no rusting. 3, planting bars and chemical anchors are widely used in building structures such as adding floors, overhanging, adding new floors, beams, columns and other basic rooting. The depth of implantation is generally 15d (D is the diameter of steel bars). Chemical anchor plays an important role in the anchorage of steel structure foundation and the installation of corbel.
