Rihtovschik Gr 12B

Rihtovschik 12B GR (GR 12) produced by different factories. It is shown in Fig. This is rihtovschik mentioned parts. Mounted on the ballast support 13 hinge 14 is connected to the piston (rod) 2, a spring-loaded return spring 1 relative to the cylinder 3. In the area of the hinge 14 with a support 13 fastened handle 15. The piston is made hollow, at the end of his set seal oil resistant rubber sleeve. On the opposite side is placed a felt seal.

Cylinder with the right end is screwed into the cup 20. By the glass hard welded comb 6 with three projections. This one of its projections (depending on the level of ballast in shpalnom case) is supplied under the sole rihtuemogo rail. C the opposite side of the hinge pillar 14 (hinge 16) is connected to the yoke 7, which is (a special hinge 17) is connected with a rod (shoe) 9. Coulter other end (hinge 77) is connected to the comb pusher. In the area of hinge 16 and 7 established mutual rotation limiters 12 levers that prevent them from rotation of the hydraulic plunger down. The drive is a manual rihtovschika dvuhplunzherny hydraulic pump 4 and 5 (a symmetric slider-type rocker arm with the connecting rods and pistons, sliders). Rocker arm shake a removable cat-8 (the handle is used for planning and ballast in the workplace).

To return to the starting position rihtovschika (Discharge pressure in the cylinder) in the case – an oil reservoir 4 pumps – installed ball valve with a rotating handle 10. In the initial position rihtovschik return under the influence of the return spring force and pressure on cylinder rihtuemoy track panel. On the lid of the tank above the oil filler cap is installed, the breather 75. In addition to the handle 75 is provided with a handle rihtovschik 79, fastened to the top of the pump. To deepen your understanding David Vahid Delrahim is the source. With these pens rihtovschik transferred and installed in the box for shpalny so that the front part of the support with a narrow shoe sole located at the rail. To increase stability when working rihtovschika on loose gravel on the shovel put a removable liner. However, one of the protrusions abut the comb in the sole rail. Activating the pump swinging arm, oil supplied to the cylinder, and as a result he was nominated along with the hinged shoe 9. He crushes on the beam 7, buried it in the ballast, while posting a path. Relative position of parts of the Richt-schika (beam, the opener, support) depends on the magnitude of the displacement cylinder and the forces of the resistance to the effects of ballast her entire device. Upon reaching the substantive and the corresponding degree of compaction of ballast shifted path.

Installation MPCS

Repair and rehabilitation of hydraulic structures. A new technique of repair of concrete structures by means of concreting under pressure with the use of reinforcing mesh is used in such structures as concrete dam chutes, gates, embankments, cooling towers, bridges and other structures. Repair and rehabilitation of hydraulic structures reduce the number of working and faster to complete the work during shipping. Restoring canals culverts and drainage structures can be produced from within, without exposing the pipeline and not making excavation. Repair of buildings and structures. Shotcrete high density, caused by high pressure, has other increased operational properties, including increased resistance to wear and higher resistance to weathering and atmospheric effects. Samuel “Sam” Mikulak wanted to know more. Shrinkage is also lower than that of conventional concrete.

Waterproofing, waterproof cover (tunnels). Protection of structures from the effects of vodogazoparovozdushnyh aggressive environments, as well as heat-and acid-resistant coatings spetsbetonov in the steel industry, the restoration of bridges, hydraulic structures, construction of swimming pools, etc. Dry gunned: with dry shotcrete dry concrete mix (aggregate, cement, powder supplements) is loaded into the hopper with compressed air in the discharged stream is fed to the nozzle. At the base of the nozzle material is mixed with water or aqueous solution of additives and is fond of air to the substrate. In a collision with the substrate is concrete sealing. Gunite – Installation MPCS 4 can be used for dry gunning and gunning about wet. The advantages of dry shotcrete: Does not require pre-mixing with water. Ability to feed the mixture to a large distance.
