Concrete or mortar mixture is served in the butt under pressure either free-mechanized or manually. Before замоноличиванием joints columns with centering gaskets gap between the ends of the columns зачеканивают rigid solution M300. In case of submission of a rolling stock solution butt under pressure зачеканка clearance is not required.
Filling the joints with a solution of (concrete) mechanized produce with plunger or screw mortar pumps, пневмонагнетателей, integrated pneumatic installations, working on the principle of gunning cement-guns and other equipment. Pneumatic engines and complete plants suitable for sealing joints-mixed concrete and mortar; mortar pumps and cement - gun - only solution. Mortar or concrete can be served in the butt directly from a hose or through the tips. Mixture submitted freely in the butt, condense vibrators.
Concrete buy бетонораспределительные стрелы, бетонный завод, вибратор глубинный.
The process of filling the joints with a solution and a concrete mix consists of feeding and stacking butt mortar or concrete mixture on the fine aggregate (10...20 mm) mobility respectively 5, 10 cm and above; пластифицирующими additives can be injected concrete mobility of 5 to 7 cm (water / cement ratio of 0,4 0,45...).
For filling the joints with a solution using mortar pumps of the solution is fed into the receiving bin of the mortar pump and pumped through the pipeline, consisting of steel pipe and hose or hose directly in a joint or in a timbering interface. While замоноличивании a few joints with a small amount of solution of applied bifurcation of 2...3 socket. Vertical joints замоноли allow, pumping solution through the hole in the mold upwards (Fig. 4.39). Sealing joints when injection of the solution is created seal mobile formwork porous rubber in the thickness 20...30 mm
Pneumatic engines used for transport and laying of plastic and hard mortars and concretes. They are complete with compressors and воздухосборниками. Some pneumo - blowers can transport only solution. When filling the joint with the help of pumps and пневмонагнетателей compacted concrete mix with pokers electrical or pneumatic. For sealing of concrete mixture in remote places vibrators equip a device in which a metal strip (section 25 X 5 mm, length 40...70 cm) or tube with a diameter of 13.5 mm, bent under the required angle is attached with two clamps to the body вибробулавы. Pneumatic installation «Пневмобетон» used for the production, transport and laying the sedentary mortars and concrete mixtures with their seal. Mortar pump unit is used as a feeder, forcing sandy concrete mixing chamber, from which he suspended the compressed air is transported through the hose and is served in the butt joint, or applied to the surface by the method of shotcrete. Application installation «Пневмобетон» provides fast and qualitative filling of seams and joints with the lowest cost of labour, as well as the necessary seal mixture and its partial dehydration.
