"transform enterprise standard reinforced concrete structures" JL ??Enterprises word J-001 II: Project Overview 1. Location: Building structure xxx2 # 2: Framework 3 Structural reinforcement situation before:. a floor cracks. 4. reinforcement measures: to ensure structural safety, meet function, shorten the construction period and minimize the economic loss principles for controlling the development of cracks, reinforced protection of concrete structures crack, cracks in the wall width is greater than 0.1mm, less than 3mm is reinforced grouting treatment. The method is formulated certain modified epoxy grout material into the slurry, with pressure to send equipment to be poured into the gap to make it fully diffused by condensation cure for reinforcement purposes. Third, the purpose and content of the role of construction epoxy modified epoxy grout material with high strength, strong bond, shrinkage, good chemical stability, can be cured at room temperature and so on. As a building structure with epoxy grout material reinforcement, you can receive the following technical and economic effect, can effectively restore structural integrity, and has closed impermeable effect after reinforcement structure look good; when you generally do not need reinforcement discontinued, does not affect the normal use of the building; the construction is simple, fast, and soon restored buildings make use of this reinforcement method can be used to repair concrete cracks otherwise difficult to deal with than other methods, low construction cost, comprehensive good economic results. Concrete cracks automatic pressure grouting technology construction method (a) Features 1. Grouting is configured lightweight, easy construction, do not need electricity, can be in any direction and altitude horizontal, vertical, etc., there are obstacles, no power under harsh field environments, adaptable, machinery noise, safe and convenient. 2. May be a crack in the entire population of the note and automatically injected grout due to internal hose and sleeves are transparent plastic, injection glance at the scene confirmed grouting effect can be completely reliable quality grout. 3. Grouting speed, high efficiency, saving period. 4. Filling resin material and supporting good performance, easy to use, low-toxic, non-irritating odor, live civilized, safe to use. (B) Scope can be widely used in reinforced concrete crack repair, finishes hollowing filling. Sealing plugging and so on. Applicable crack width in the range of 0.05 ~ 3mm, based on the type of structures can be divided into categories: 1. Buildings. Repair (1) concrete walls, interior walls, roof trusses, beams, floor, roof, etc. crack reinforcement. (2) cement wall surface, tile, stone and other parts of the hollowing filling. (3) on coagulation structures: such as cracks silos, prefabricated, equipment foundations, pools, dams, bridges, tunnels, concrete roads, pipelines and other patching, sealing plugging. (C) the use of low-pressure injection process principle principles, relying automatic pressure grouting the spring pressure and capillary principle, supporting AB series automatically inject concrete grout resin micro-cracks or holes hollowing parts, making it completely filling and bonding firm, the ability to achieve the overall recovery and improve the durability of concrete and other purposes. (D) a process and operating points. Process is as follows: Cracks primary treatment → → closed cracks, install the base ingredients → → → grouting grout removal device → dismantle the base and restore the status quo ante grassroots → effect checks. 2. Operation points. (1) Crack investigation. ① observe the status and distribution of crack, the survey structure profiles, cracks Cracking, development. ② identified and marked crack width, thickness of concrete verification, check for leaks, whitening situation. 10 times with a magnifying glass to crack crack width is measured and marked at the top of cracks through the cracks if you want to specify. (2) primary treatment. ① cracks along the direction of the primary surface to remove dust, floating skin, hollowing decorative layer, the corrosion layer, if necessary, with a cotton dipped in alcohol to scrub the surface of the wire. ② for Honeycomb concrete, exposed tendons injury site with quick-drying Sealing glue repair can repair the defect at serious polymer mortar. ③ moisture or water should be brushing a primary interface agent treatment, the grass-roots dry impermeable. (3) closed cracks, install the base. ① Select the location based on the crack grouting mouth, the general election in the easy injection site, such as cracks wider at the confluence of crack branching, etc., grouting port 20 ~ 1000px appropriate distance apart, the finer cracks, the shorter the distance. In ordinary tape affixed grouting mouth position. Leaving in need through the cracks on both sides grouting mouth. ② will be tuned Sealing glue applied to the crack surface, with a Knife ensure strict crack completely closed, sealing seam glue width of 2 ~ 100px, thickness 0.8 ~ 1.0mm. Through the cracks on both sides need closure. ③ yer holes for the tape, with YJ- Sealing glue stick on the base into the plastic mouth, round the base must be aligned with the crack grouting mouth. ④ per meter crack leaving 1 to 2 base as a vent and a slurry outlet, horizontal fracture distal ends of the cracks remain in the smaller area. ⑤ until after sealing seam glue is completely dry, you can start grouting. (4) ingredients. ① Select grout resin and resin models based on the performance characteristics of the crack width, one can refer to the selection table. ② B-component resin grout rata weighed mixed evenly pour the filling hose should be used with the distribution with a time of not more than 500g. (5) begin grouting, grouting confirm status. ① The grout is install in the end seat, relax spring, start grouting. General bottom-up, a slurry outlet at the highest glue. Due to the small cracks can not be used in real-time high-pressure injection pump dispensing aid construction. ② grout hose into the cracks in the slurry has been basically, you can always replace the grout, a supplementary injection until the crack is filled. When grouting volume has more than theoretical value, into the plastic rate slowed down to almost no longer into the plastic, and the plastic mouth slurry outflow, indicating that the crack has been basically full, then plug the first with a plastic mouth blocking Yan, grouting continues to maintain the state in order to avoid slurry grouting back. Crack repair resin is about the actual needs of 1 to 5 times the theoretical amount, after the abnormal situation should identify the reasons for treatment. Determine the theoretical amount of resin injection, according to the crack width, depth, length
