Jiangsu large plugging Engineering Co., Ltd. specializes all kinds of waterproof, plugging technology research, the first batch of Jiangsu Province Production Safety Supervision and Management Bureau of high flying job safety qualification level enterprises, China's anti-corrosion construction-related professional power system two qualifications, the state issued two waterproof qualified enterprises. Now developed into 18 projects department, more than 900 employees, construction machinery, fully furnished, has accumulated a wealth of production experience and a complete set of scientific management in the building waterproof plugging project, the company implemented a comprehensive, multi-level responsibility contract, in order to mobilize all positive factors, quality and cheap, short construction period, a good image of honesty and trustworthiness, in the fierce competition in the construction market have been developing steadily. Patented technology: the company and the professional waterproof material manufacturers and many years of research and technology research institutions crystals with water operations have anti-pressure sealing patented formula, apply pressure grouting underground air raid shelters, hangars, pumping stations, reservoirs, dams tunnel rock group, to the cable channel and other projects plugging, trapping, anti-penetration, in the pool, cesspools expansion joints, cracks off, cross joints waterproof plugging, plugging basement waterproofing, waterproof plugging underground civil air defense projects, Shen plugging wells, elevator shafts seepage, waterproofing plugging culverts, construction experience tunnel, railway tunnels, bridges, tunnels waterproof plugging, etc., to undertake the difficult and challenging waterproof plugging engineering tasks. Joints plugging a principle, we take a different approach depending on the circumstances of the project, the general case of using the principles of "blocking row combined to row-oriented", but in some cases no drainage system engineering, we all use high-pressure injection plugging slurry method. 2, high-pressure grouting plugging principle: form a chemical bond to crack; pore surface to form a high strength bolt; filling all cracks under high pressure to push. 3, high-pressure grouting plugging is the use of high-pressure grouting machine, the water-soluble polymer material is injected into cracks in the concrete, concrete cracks in the water will quickly disperse when the slurry is encountered, emulsification, swelling, consolidation, consolidation so resilient body filled with concrete all the cracks, will completely block the water flow out of the concrete structure in order to achieve the purpose of sealing plugging. High Pressure Grouting and Technology is an internationally advanced level of high-pressure airless water infusion of new technology, it is a new technology developed water-soluble grouting material used. 4, basement seepage water comprehensive management of first holes, loose water leakage and other major defect portion careful look at the process. This step is the key to the whole plugging, must be carefully, carefully carefully take the trouble to do. Only on this basis can be carried out on the second step of plugging processing. Plugging effect and material relations are very close, materials for sealing technology provides the basic conditions and play a security role, superior performance, high-grade material is ultimately reflected in the use of technology, no matter what material it must be with the sealing technology Operating match fit. Therefore, this project waterproof, plugging the selection of materials as follows: preparation and production of special fast-setting, the expansion of plugging plugging polymer materials for repair; 3.1 Construction principles 3.1.1 Summary of a grouting grouting method is one. kinds of chemical grouting plugging technology, which uses double grouts. Proportionally weighed three materials add water and stir into solution A, according to the proportion of Sulfur weighed add water and stir into solution B, when the two liquids mix after the polymerization reaction, the initial setting of 30 seconds, 2-3 minutes the reaction is complete, the final cemented colloids. Grouting injection structure layer using water-soluble form, low slurry viscosity, permeability, can be injected into the cracks under 0.1mm; slurry in the wet, the water speed large, multi-criteria aggregation under water; gel also has good permeability, in case expansion of water, corrosion resistance and other characteristics, colloidal compressive 0.01-0.06MPa, tensile strength 0.02-0.04MPa. b. grouting method is mainly used in a large amount of water leakage, water dispersion is not conducive to sealing cracks and individual water points, faces. Crack sealing position is determined according to the situation. Internal grouting to seal the water channel and crack, or makes the water flow is relatively concentrated, easy to block. Leakage greater than 150mL / min centralized point of water, using water shutoff grouting method. On the first water point drilling, drilling depth so as not to penetrate the structure layer, not less than 20cm is appropriate, both to avoid slurry hyperdiffusion phenomenon, but also to clear the water around the point of fine cracks appear intertwined grouting, play relief role. Then float hole gravel ballast clean, quick-gel mud to an outer diameter of 25mm bore plastic hose buried in water, and then the mortar dressing mouth. 3.1.2 Grouting concrete construction steps a surface treatment: surface cracks of about 10cm handle clean, find the gap position and water. . b slotted or drilled: seepage cracks in the left and right 3cm cut with a cutter at 6-8cm deep seam preparation for gouges. c gouges: artificial carved a depth of 8cm (construction joints) or 6cm (liner cracks) in the slot, usually hewn large (6cm) external small (4cm) inverted trapezoidal groove to ensure topical waterproof layer 2-3cm thick. d embedded grouting tube: For between the sleeve seam buried water pipes and leaking, the first of leakage points chiseling depth of not more than 70mm, the water washed away after installation hemp rope, and then sealing materials for closure 1-2 grouting pipe embedded diversion. . e grouting: such as waterproof plugging mortar material reaches a certain intensity, from the tube into the slurry grouting; grouting pipe alongside the corresponding effluent slurry grouting case judgment, sought slurry filled the gap and distribution; grouting pressure control 0.3-0.4MPa, is generally determined by field tests; grouting is completed, iron Sizha prison grouting nozzle to prevent the outflow slurry; Once the slurry sclerosis, cut grouting pipe. . f swabbing leveling: waterproof mortar reaches a certain intensity, wet the repair area, brush 1: 2 ordinary mortar, thickness 0.5-0.8cm. g conservation: 3.1.3 Grouting in principle be water conservation point three days before the drain water injection grouting smaller, larger after injection; in the ring in order to crack the upward grouting; horizontal or diagonal crack in the water. grouting smaller end to the larger end; Leakage from the periphery to the center in order grouting. 3.1.4 Grouting end standard considerations of surface leakage if water has effectively block principle. Technical measures to ease the closure of grouting: hole in the cloth should consider the existing grouting plugging leakage of water, should be carried out in the grouting grouting grooming, which is to inject the slurry, when leaking water there gradually changing the slurry overflow slurry concentration, adjust the slurry gel time, so to divert water leakage at the sealing by grouting from the inside out. If grouting part leaks can not achieve the purpose of the overflow slurry, then a leak point bore grouting, so as to achieve a slurry filled from outside to inside and closure. 3.2 Governance 3.2.1 leakage area classified special part joints leakage control program expansion joints (Deformation) is apt to leak, according to the actual situation of the Party and engineering requirements, the need for crack grouting waterproof plugging leakage spot drain, according to the specific circumstances of compressive sealant waterproof protective layer of rigid construction again. a. First construction joints cutting a deep 40mm, width of 60mm "V" type joints, rinse with water. b. Fixed grouting channel and grouting pipe with more than 2.5 ordinary portland cement grouting channel fixed PE foam strip, at a fixed PE foam strip, about 50cm every one buried grouting pipe, grouting tube with 10 -13mm of pressure rubber hose, the tube has been used as water pipes and as grouting works. c. Grouting and sealing and flexible seal waterproof construction starting from one side of the polymer injection grouting material grouting pressure control between 0.3-0.5MPa, grouting to be next to a hole to stop grouting take slurry, and close the valve hole Grouting and then from another, followed by the order, until all leaks observed grouting is completed, there are still some places such as leakage can not leak until a hole from the recent supplementary grouting so far. Before making a cut pipe sealant construction. The company will adhere to the people-oriented, comprehensive establishment of modern enterprise system to regulate the operation of `Fan, stick to science and technology enterprises, quality-level of the road, follow the new adults" quality first, the owners first, abide by the contract, quality service, "the purpose of" unity, cooperation , rigorous and realistic, high-quality, pioneering and innovative "spirit of enterprise, carefully creating excellent project, with the best quality services to new and existing customers.
