Mortar pump in construction and grouting technology

Mortar pump uses: First, the mortar pump delivery In the construction project, the mortar pump to complete the mortar pump to complete a variety of brick and concrete block structure of the ground, wall plastering mortar and masonry vertical or horizontal delivery , Mortar and masonry mortar and other vertical or horizontal transport equipment installed as shown in Figure 1 below. Pumping mortar is very similar to pumping mortar and pumping concrete. Pumping technicians experienced in the process of pumping concrete are very familiar with mortar pumping operations. Second, the application of grouting technology in grouting technology Mortar pump in geotechnical grouting technology for pressure below 6MPa hydrostatic grouting, grouting operations can be summarized into four categories: 1, Filling or fissure grouting large caves, tectonic fault zone, tunnel lining wall after grouting. Seepage control of joints and faults and seepage prevention of faults and consolidation grouting. 2. Permeate Grouting The grout can be filled into the particle gap without damaging the formation particle arrangement, and the particles are cemented into a whole and the particles are cemented together without breaking the formation particle arrangement. The necessary conditions for osmosis grouting are that the particle size of the slurry is much smaller than the particle size. The necessary condition for grouting is that the particle size of the slurry is much smaller than the particle size. 3, compaction grouting Compaction grouting is injected into a very thick slurry, the formation of spherical or cylindrical slurry, compaction around the soil, compaction grouting is injected into a thick slurry, the soil plastic deformation, but the plastic deformation Does not make the soil produce splitting damage but does not make the soil produce splitting damage. 4, split grouting split grouting grout slurry in the hole with the grouting pressure increases, the first pressure around the soil when the pressure reaches a certain extent split grouting slurry in the hole with the grouting pressure Increase the pressure of the surrounding soil first when the pressure reaches a certain level, the flow of slurry fracturing the formation, the formation of veins or ribbon-like cement to form veins or strip-like cement. Mainly used for soil consolidation, fractured rock seepage enhancement. Third, the application in the mortar spraying and other fields In the mortar spraying and other fields of application Mortar pump in a variety of building large surface coating of overlay mortar, mortar pump in a variety of building surface coating of a large area The surface quality of mortar depends on the proficiency of the operating workers However, the surface quality is determined by the proficiency of the operating workers, after the construction requirements can be manually trowel or do not wipe the equipment installed as shown below.

Silicone Turner is made of silicone and nylon for the perfect combination of flexibility and hardness. getting under delicate foods, while the head's face is made of silicone so foods won't slide off as you're flipping or turning them.
