UB3C灌漿泵是輔助灌漿設備。輔助灌漿水灰比可達0.33，在可灌性、管道密實性、漿體強度 等方面均比普通壓力灌漿要好，因而得到廣泛應用。
Successful grouting operation is vital to the durability of post-tensioning system. VLM’s experience with grouted post-tensioning tendons showed that a cementitious grout can provide excellent protection to the prestressed tendons. The bond between the concrete and the prestressed steel as well as long term corrosion protection for the prestressed steel depends largely on the hardened cement grout.
Whether it is internal bonded tendons, external tendons or slab tendons, the quality of the grout determines the durability of the post tensioning tendons.
VLM has developed advanced methods of grouting such as pressure grouting, post-grouting and vacuum grouting, and also offers a complete range of grouting related equipments like corrugated duct forming equipment (both metal & HDPE plastic ducts), cement mixer, grout pump and vacuum pump. These grouting equipments are designed to work well with the grouting methods and solution in order to achieve a homogeneous grout mix to attain the highest grouting quality.
Projects these days are more demanding, especially for deep and inclined tendon profiles, long vertical cables, long loop tendons or tendons (external included) with access / vents. VLM is equipped with the capability to overcome these challenges to produce quality grout and to ensure the durability of these post-tensioned structures.
VLM Grout Pump (UB series) is suitable for pressure grouting, post-grouting, as well as vacuum grouting. This is due to its highly versatile and compatible nature. Its lightweight and high pressure capability made it the operator’s choice for tomorrow’s grouting challenge.
