High-strength non-shrinkage grouting material for anchor bolt anchorage and buried steel plant

Anchor bolt anchorage and buried steel plant s bolt anchorage and planted buried steel bar embedment depth should meet the requirements of design specifications. Recommended embedding depth: 15 d (p D: the bolt diameter) Adopting high-strength non-shrinkage grouting material for anchor bolt anchorage and buried steel. Anchor bolt hole, foundation concrete strength shall not be less than 20 mpa, the level of the bolt hole deviation shall not be greater than 2 mm, verticality deviation shall not be greater than 1%. Anchor bolt of oil and rust must be cleared away. After into the hole, should remove the depth of the hole sundry, test hole, and fully wet hole wall with water. Within the hole should be removed before grouting water. After the bolt insertion should be corrected its horizontal position and at the top of the height, and fixed. S high-strength non-shrink grout material anchorage anchor bolt, shall meet the following requirements. Of good mixing high-strength non-shrinkage grouting material into the bolt hole, the grouting is strictly prohibited in the process of vibrating, dao. May not be adjusted after the grouting bolt. High-strength non-shrink grout material is not easy to direct injection, grouting construction appropriate USES chute auxiliary construction.
