Who nearly waterproof plugging term treatment works construction, no one quality complaints, with tough waterproof plugging ability, construction performance throughout the country. The company's technology is strong, waterproof focus on training of technical personnel. Has 15 engineers, 50 technicians, professional staff of 180, the construction process in strict accordance with current national plugging waterproof construction engineering technology implementation of standards, with the successful resolution of all types of buildings (structures) anti-leakage site needed moisture and seepage water seepage construction technology skills had contracted the Shanghai Yangshan Port tunnel waterproofing plugging, Zhejiang alloy high speed 3000m tunnel waterproofing plugging, Tianjin 20th Metallurgical Construction Corporation basement waterproofing plugging, Hangzhou, Zhejiang Electric Power Grand Canal plugging tunnel waterproofing, Nanjing Huaneng Power waterproof plugging the cable trench and a number of major national projects to solve a considerable part of waterproof plugging problems, praised by all my colleagues. The company has advanced equipment, strong technical force, high-quality management and construction team, Nanchang elevator shaft plugging company through ISO9001: 2000 international quality system certification, ISO14001 environmental management system certification, OHSAS18001 occupational safety and health management system certification. Pressure grouting waterproof plugging a construction program, Nanchang elevator shaft plugging seepage reasons: Basement area 1200m2, 70 centimeters under the concrete floor area 1200m2, 5-7 cm high storage space, due to the surrounding structure high water level, the forces caused by underground storage space for a long time, namely: to cause a large area of ??water seepage in the basement floor; the second is: to make concrete long-term immersion in water, the concrete early deterioration. Second, the construction of a main application materials, materials Introduction The appearance of the product is light yellow to amber transparent liquid, which is in line with the polyurethane prepolymer with a variety of additives made of one-component high-pressure sealing materials, a fast and efficient Consolidation can both plugging reinforced polymer elastic material. Can be applied to a variety of projects from the Water Seepage reinforcement effect. 2, material characteristics (1) The material has good hydrophilic, can react with water, while generating CO2 gas, and against the current along the runoff channel penetration and diffusion, with the surrounding concrete, sand, soil and other consolidation, rapid forming an impermeable layer of hardened consolidation, has been widely used to block large pressure and prevent ground water gushing in water and water infiltration. (2) the material and concrete and soil particle bonding force, elastic consolidation can obtain high-strength body, so can fully adapt to the foundation or other primary deformation, it is not easy to find the beginning of the crack, and the resulting collapse reinforcement strong. (3) will not be broken up in an aqueous slurry of the structure, in which the reaction process, because the gas diffusion zone increases rapidly the effective consolidation obtained larger than many other types of chemical grout consolidation thereof. (4) According to the different needs of the project, you can adjust the viscosity of the liquid filling, and for small cracks after grouting concrete projects, such as basements, etc. can quickly penetrate into the slurry to form a strong bond, good permeability, strength of solid guitar body. (5) the slurry curing speed can be adjusted according to the construction. (6) the use of a single device to divide filling, easy to clean, simple and easy process, lower overall cost of construction. (7) consolidated body immersed in water is harmless, non-toxic, non-polluting. 3, material and technical guidance Item Specification Appearance: Light yellow - amber transparent liquid, Density: g / m3 1.0 ~ 1.10. Viscosity, 20 ℃, Mpa.s 100 ~ 400. Gel time tens of seconds to several very cohesive strength Mpa ≥1.0. Expansion,% ≥ 300. 20 pack of water three times, a construction organization, the project manager responsible for the implementation of the project system 2, the construction management system six, construction and operation of process points 1, the construction process: determine the leakage point → clean up leaking base surface cleaning → → → drilling installation then the mouth filling perfusion pressure foam slurry → → → trap observe the demolition of filling the mouth → → → Check → acceptance slot patch 2, construction elements (1) quasi-seepage point play, the seepage area, clean up. (2) with a rapid sealing agent embedded grouting tube spacing should be based on the actual circumstances, generally about one meter. (3) with an electric high pressure injection pump, the water-soluble polyurethane sealing agent injected into the gap from the grouting concrete pipe joints, until the pressure does not enter until (injection rate ≤0.011 / min) closes the valve, 24 hours after the circumcision (removal ) grouting Tsui. (4) In order to achieve long-term water purposes, and then in the face of the surface layer of polyurethane waterproof construction brushing. (5) grouting is completed in a timely manner with solvent cleaning equipment and tools. (6) the construction site to maintain ventilation, avoid fire, fire is strictly prohibited. 3, high pressure grouting plugging construction method (1) of this construction method is the use of huge high-pressure perfusion machine generated, the material sent to the middle of the wall of the gap, the intermediate material is part of the center to the edges, and rapid response materials and water After hardening, the gap reached tamped foundation reinforcement, plugging seepage effect. (2) high-pressure grouting machine used in this construction method, perfusion pressure, flow, fast sealing, indeed effective blocking hydraulic method. (3) Method of perfusion-point of the perfusion was started from the central position of the structure, especially for a thickness greater than 1000px more concrete wall, it is fast and efficient sealing work using the present method. Seven, Nanchang elevator shaft plugging Notes 1, Construction Notes (1) When the grouting, grouting tip buried put reasonable, closely monitor pressure-proof tube. (2) The operator should wear glasses, masks, gloves and other protective clothing to prevent slurry splashed in the eye. 2, the storage of chemical grouting materials Notes: (1) chemical grouting material should be sealed and stored in a cool dark storage room, and a personal custody, custody staff should be familiar with the material properties. Container (2) material should be equipped with a clear label affixed, and the need to classify storage. (3) a place to store chemical grouting material should be prohibited fireworks. 3, chemical grouting staff should note the following: (1) staff should wear gas masks, rubber gloves and boots and acid wear overalls. (2) if tired at work, foot blisters, hand-toe numbness, dizziness and feeling immediately from the scene to fresh air supine rest. (3) In case of a slurry or powder into your eyes or touch your skin, wash immediately with plenty of water, medical care immediately if in pain. (4) must immediately wash your hands before you eat, you should take a shower after work. (5) should be careful not to make the slurry flow into drains and rivers, so as not to pollute the water. Eight, a quality assurance measures, strictly to good quality material, the use of chemical grouting material, with product certificates, brochures and technical reports, before construction site sampling re-examination after passing through, never use inferior products. 2, strict rules and technical specifications, do not cut corners in construction. 3, adhere to inspection and acceptance system, adhere to self-inspection, mutual inspection and seizure. Nine, a security measure, grouting plugging agents auxiliary materials used in this project are flammable material library construction site and non-smoking, and equipped with a sufficient number of fire-fighting equipment. 2. All persons entering the construction site all with helmets. 3, before entering the construction site for all construction personnel safety education, so that everyone can talk about safety.
