What are the pedestal grouting material construction step

Bearing grouting support grouting material manufacturer support grouting material price front step: root root appearance should be cut wool processing. Clean toes in appearance, can not have crushed stone, laitance, floating dust, oil and demoulding seam an agent and other sundry. 24 hours before the grouting, root appearance should be energetic wet, 1 hour before grouting, the eradication of water. Step 2: touch 1, according to the grouting construction drawing for the template. Template and roots, templates and template seams between water mud, adhesive tape, such as seaming, arrive all the template does not leak. 2, templates, and the horizontal distance around the equipment base should be controlled in 100 mm or so, to facilitate grouting construction. 3, templates, the top level should be above the equipment base appearance 50 mm. Pulp, such as in 4, the grouting should be processed in a timely manner. Step 3: support grouting material preparation 1, in general, according to general rugged according to 13 - 14% of the standard water bearing grouting material selection's mixing, pisolite rugged in September 10% of the standard water mixing. 2, recommended to choose mechanical mixing method and mixing pedestal grouting material can add stones moment for 1 - commonly 2 minutes ( Ban hand electric drill type mixer) 。 To choose artificial mixing, should be in two-thirds of mixing water for 2 minutes, then take part in the remaining water mixing evenly. 3, every time mixing quantity should depends on how much usage, to ensure the material use up within 40 minutes. 4, when used on the scene, forbid in the HGM pedestal grouting material mixed with any beautiful seam an agent, the additive is applied. Step 4: method of secondary grouting, grouting construction should agree with the following requirements. (1), secondary grouting, should from the side or on both sides of the adjacent points for grouting, until the spill stopped on the other side, to facilitate the exhaust gas in the process of grouting. Grouting will be made from the four side and at the same time. (2), the grouting after beginning, should be carried out in succession, not continuous. And shorten the grouting time as much as possible. (3), in the process of grouting vibrating is prohibited. Necessary available grouting booster along the grouting at the bottom of the layer to promote HGM pedestal grouting material, banned from grouting layer, upper propulsion, to ensure that grouting layer uniformity. After the grouting, (4), the equipment foundation should be 3 - after grouting 6 hours along the device marginal to cut 45 degree Angle ( See image below) In order to prevent the crack free end, such as unable to handle trimming, heilongjiang bearing should be 3 - after grouting grouting material manufacturer After 6 hours with a spatula grouting layer appearance calender. (5), when grouting layer thickness of more than 150 mm, should choose pisolite rugged high strength without shortening the pedestal grouting material. 6, when large amounts of grouting, pisolite rugged pedestal grouting material mixing should choose mechanical mixing method, in order to ensure the grouting construction. Step 5:1, 30 minutes after the grouting should be immediately sealed wet grass cover quilt or rock, and moist. 2, winter construction, maintenance measures should also fit the current & lt; < Reinforced concrete engineering construction and acceptance specification & gt; > ( GB50204) The relevant provisions. 3, bearing moment after grouting expect to open membrane, can be the next step of construction, concrete moment see 'film and maintenance time and the relationship between the ambient temperature table'. 4, at the end of the grouting, if want to get rid of some, can be in 3 - after grouting After 6 hours, or layer grouting with a spatula or shovel tools before hardening quietly eradication.
