Product Name: | Subgrade Reinforcement special grouting material, bridge strengthening grouting materials, equipment, anchor bolt |
Published: | 2011-12-17 |
Product Type: | HGM |
Product Description: | Grouting material to use "Contact: Mr Xie: 15942891255" 1. Foundation grouting material handling Cleaning equipment based on the surface may not have gravel, floating pulp, dust, oil and release agent and other debris. Before filling 24h, equipment foundation surface should be fully wet. Before filling 1h, should drain water. 2. Grouting material filling method to determine Base of the device the actual situation, select the appropriate grouting method, as CGM has good flow properties, under normal circumstances, use the "grouting weight" can be, be poured into the slurry directly from the mouth template, totally dependent on slurry self-respect and self-leveling fill the perfusion space; if the perfusion area of large, complex or spatial structures, especially small and far apart, we can use "high funnel filling" or "pressure grouting" grouting to ensure that the slurry fully filled every corner. 3. Support mold filling material Grouting under way to determine the support and filling drawings set the template, the template positioning device should be higher than the base elevation of the surface at least 50mm, set the template must support strict, secure, prevent loosening, leakage of slurry. 4. Mixing grout By product certification on the recommended ratio of water to determine the amount of water, mixing water should be potable water, the water temperature to 5 ~ 40 ℃ is appropriate, can be mechanical or manual mixing. Mechanical agitation, the mixing time is generally 1 to 2 minutes. Artificial agitation, are advised to add 2 / 3 of the water stirring for 2 minutes, then add the remaining water to continue to stir until uniform. 5. Grouting material filling Grouting shall meet the following requirements: 1). Slurry poured from the side until the other side of the spill so far, to facilitate the discharge device between the base and the concrete foundation of the air, so that filling full, not at the same time from the four sides of the grouting. 2). Grouting began, must be continuous, without interruption, and filling time should be as short as possible. 3.) Should not be vibrated in the filling process, if necessary, can be used to pull the bamboo strips, diversion. 4). Each filling layer thickness of not more than 100mm. 5). A long track-based equipment or filling, should be sub-construction. Appropriate length of 7m each. 6). Grouting process is found in the phenomenon of surface bleeding can be a small amount of CGM dry feed dispenser, drain water. 7) The thickness of greater than 1000mm of filling a large volume of equipment foundation grouting, grouting material in the mixing ratio of 1:1 while the total by adding 0.5mm stone, but subject to testing to determine whether it can meet the requirements of irrigation. 8.) Foundation grouting equipment has been completed, to remove part of the filling level should be processed before the final setting. 9.) Until the construction process in the filling ejection, should avoid filling layer subjected to vibration and impact, to avoid damage to the filling layer of outstanding hard. 10) template base with the equipment should be controlled in the horizontal distance of about 100mm, in order to facilitate grouting. 11) filling the slurry run phenomenon if there should be a timely manner. 12) When the equipment foundation grouting is large, mechanical agitation should be adopted to ensure the grouting. 6, the grouting material conservation 1) within 30 minutes after filling, spraying curing compound immediately or cover and seal plastic film such as rock wool is the conservation, or in the filling layer immediately after the final setting sprinkler moisture conservation. 2) winter construction, conservation measures should be consistent with the existing "Acceptance of reinforced concrete construction" (GB50204) the relevant provisions. 3) under different temperature conditions in the curing time and form removal schedule Daily minimum temperature (℃) removal time (h) curing time (d) -10 ~ 09 614 0 ~ 57210 5 15487 ≥ 15 24 7 Application (1) to be the basis of high-precision equipment that has a filling device and secondary grouting. (2) buried steel plant and building, anchoring in geotechnical engineering. (3) Building Strengthening and Rebuilding Project, column connection, deformation joint, construction joint pouring. (4) roads, bridges, tunnels, airport construction and other projects using the emergency repair. (5) Anchoring of railway sleepers. (6) Column wet clad reinforcement angle and column space for joint perfusion. ★ grouting material reference to the amount Calculated by reference to the amount of 2.28 to 2.4 tonnes / cubic meter and calculated the actual usage. |
