Waterproof plugging the cable channel dedicated to industrial and civil buildings waterproof construction, construction of water remediation service: Metro waterproof maintenance, repair water seepage tunnel, reservoir water seepage, water seepage dams, highways waterproof, highway slope waterproofing, basement water seepage water seepage and other related projects, working with the Government of the emergency rescue repair reservoir dam, the slope of the professional companies in the event of a disaster. Concrete is a porous gel artificial stone, is a rigid body, the main features of high compressive strength, low tensile strength, elongation small, easy to produce shrinkage cracks. The most common cracks in concrete engineering problem is due to shrinkage deformation constraints caused by shrinkage cracks caused by external loads and load (force) cracks. Concrete cracks appear is very difficult to avoid, but can prevent and governance. After treatment the cracks are cracks root of this problem to be solved. Concrete production due precautions to prevent harmful cracks appear. Cracks appear harmful, it should be carefully governance, removal of harmful cracks to ensure security, stability, durability and no leakage of water concrete structures. 2, appears (1) The basic concept harmless crack crack for structural durability, security, stability no effect; (2) crack no leakage of water, and not through; (3) the crack width of less than 0.2 mm, and does not leak water; (4) self-healing fractures. Cracks governance should adopt a combination of grouting and sealing, grouting materials and sealing materials shall meet the requirements of waterproof durability, should be tested. And Proven, reliable quality materials; reasonable selection program properly, reliable construction management in place. 3, concrete cracks governance should collect information on (a) concrete material information: the amount of cement, water-cement ratio, sand ratio, sand ratio, admixtures (fly ash and admixtures); (2) Concrete Information: Construction When environmental conditions, weather conditions, temperature conditions, pouring concrete sequential, concrete quality, slump loss and lower heat of hydration measures, conservation measures removal time, removal time, form removal order, concrete; (3) the temperature Control Information: into the mold temperature (the temperature of raw materials into the mold temperature = + + temperature rise when the concrete mixing concrete transport temperature), the highest in the concrete hydration heat temperature, the inside temperature of concrete and sheet temperature, concrete temperature drop gradient; (4 ) structural design information: specific measures to control concrete cracking, additional waterproofing layer is set, construction joints and Deformation, back strip and other settings, reinforcement methods. 4, concrete cracks survey sites (1) of cracks (arches, walls, bottom) direction (vertical, oblique, horizontal) crack, crack width, depth, length and extension direction. Pressure grouting plugging - Method characteristics: the enormous pressure generated by the high-pressure perfusion machine will crack sealing agent to the wall of the middle part, so that the middle of the crack sealing agent to the center to the edges. After plugging reactive curing agent and water fast, the cracks permanently blocked, especially a thickness greater than 20 cm above the concrete wall body, plugging using this construction method is fast and efficient. High-pressure grouting machine used in this construction method, the perfusion pressure, flow, fast sealing, indeed effective blocking hydraulic method. Especially for the amount of gushing water leakage point, this construction method is more magic. Scope: subways, tunnels, culverts, site improvements, reservoirs, Harbour Engineering, roof, cracks, construction joints, expansion joints, basement hairline cracks stanch projects. Due to the long-term effect of water pressure in the concrete due to carbonation, freeze-thaw damage or corrosion medium erosion will cause varying degrees of leakage. Reinforced concrete leakage will cause corrosion, which will reduce the strength of concrete and shorten its life. Concrete production process, from raw materials only, preparation, mixing, transportation, irrigation, health, integrated test filter to control does not appear less concrete cracks, do not crack does not leak. Second, the concrete cracks in the concrete cracks control method according to sound management of hazardous cracks and cracks in governance, this paper focuses Introduction harmful treatment cracks. Concrete leak leak causes: In the long run time underwater hydraulic structures, for dam, due to leakage of the concrete will directly affect the safe operation of the dam, serious and even affect the majority of residents downstream safety, so the concrete leakage control is very important. Cracks governance should adopt a combination of grouting and sealing, grouting material and sealing material should be filled waterproof durability requirements should be tested. And Proven, reliable quality materials; reasonable selection program properly, reliable construction management in place. Cause leakage of concrete points: Concrete holes caused by improper, templates and other wear screw hole is not timely closure or sealing leaks, steel corrosion caused by leakage caused by improper, wall pipe and other construction details remain set up to address leakage and leakage secondary construction or renovation construction accidentally damaged the original waterproof layer caused by improper. Third, the main causes of line leakage are: 1, Deformation waterproof design, construction is unreasonable, 2, sealing copper, and other materials of poor quality or water stop seal due to aging and other reasons caused the failure 3, failure to keep facilities construction specifications industrial sewing or combine old and new concrete rigorous treatment, resulting in construction joint leakage 4, because the concrete mix properly, resulting in increased drying shrinkage, or due to structural deformation, thermal stress and other reasons to make concrete cracks, 5, joints between different materials due to improper water treatment, the resulting leakage. The company has a waterproof plugging the cable trench engineer have ten, twenty intermediate grade technical personnel, project construction management team of excellent quality, business contracts and keeping promises, my unit was assured users << Economic and Trade Commission granted in satisfaction with the quality of corporate integrity >> << >> construction units with construction title. The company on the date of the completed project waterproof maintenance tracking service, regular visits, inspection, maintenance, sent when the quality problems in time, since the delivery of the company's commitment to provide 5-year quality warranty responsibility, to provide customers with secure, timely and efficient service. The new big company's aim is to develop, research, promotion of new technologies do not stop with pressure seals, new products and services in business processes. In recent years, in order to promote the use of technology, has held 69 technical training, trainees pass the exam, and has made special equipment operator certificate has reached 1,000. Now certified personnel have become the backbone of enterprise technology, production equipment maintenance safe operation plays an important role in creating a huge economic and social benefits for the enterprise energy saving and environment-friendly.
