These swivel pins used as a shaft of seizures 11. The seizures have two pairs 11.1 and 11.2 double-arm lever that can be rotated in opposite directions. Each pair of double-arm arm consists of two left two levers 11.1L and 11.2L and two right-wing two levers 11.1R and 11.2R.

Two levers of each pair, which are parallel to each other, connected to each other on the end of one arm, shoulder, gripping device, cross-piece. These crosses and designed to serve as Cams 12 gripping device for clamping and gripping the end of the truss rod 3.

Two levers of each pair, which are parallel to each other, attached at the free end of another shoulder, shoulder of the lever, to which force is applied to a pair of elbow fitting levers.

Block 13 actuator crank lever is used to control seizures. Grips are routed so that they glided, concentrically to the outer circumference of the Central unit and the guide tube 7, attached to it, on the outer perimeter of the guide tube. Block 13 is used to control two identical pairs 14.1L and 14.2L crank arm, and 14.1R and 14.2R that with their Central compounds 24L and 24R is connected to the pins from both sides, left and right, drive unit crank arm and attached to their free ends, in each case, to the other end of the double-arm levers 11.

Hydraulic drive 15 of the grasp formed inside (FIGU) block 13 actuator crank arm, forming a cylindrical chamber 16 with the Central unit and the guide tube 7, which features a Central unit, and the unit 13 actuator crank lever in front of the Central block, you can move the piston method. Cylindrical chamber sealed opposite guide tube 7 on the ends, and it has a hydraulic connection 17 (Figo). Block 13 actuator crank arm rests on the spring 23 opposite guide tube aimed at weakening crank lever so that pairs crank arm curved around the joint 24L and 24R crank arm, and Cams 12 grasp moved to weaken. Drive 15 hydraulic gripping device functions in such a way that block 13 actuator crank lever is moved against the spring force 23 hydraulic pressure, created in the cylindrical chamber with the aim of lengthening pairs crank arm. Through this lengthening Cams 12 gripper are displaced to lead so that the Cams of the grasp firmly seized anchor rod 3, provided carvings on its periphery, clutched at the Central block by swing pins 10R and 10L, and Vice versa. When this is done through the drive gripper, who exert hydraulic pressure, inlet tube 8, you can push sealing way into the opening of the inner channel 9 truss rod 3 with stationary mixer, placed in it. With this purpose, use the hydraulic sealing drive 19. It was founded supply pipe on its external peripherals, designed in the form of step piston 20, which is within the Central block of the 5, constructed with multi diameter, forming a cylindrical chamber 21. This cylindrical camera divided sealing way on one side by the end of the inlet pipe 8 with a large diameter, and on the other side - step reduces the inside diameter of the Central unit 5. Cylindrical chamber 21 is connected with the hydraulic line 22.

If the inlet pipe of 8 pressed into the bore of the inner channel 9 truss rod 3, you can submit plastic components. For this two tubes placed in the inner channel inlet pipe 8, in particular the inner tube of 26 and outer pipe 27, which are concentric with respect to each other. To connect these pipes with plastic feeding tubes 28, 29 on the Central unit is screwed fluid coupling 30, in particular at the end of the guide tube extending from the block 13 actuator crank arm. Hoses, plastic feeding tubes 28, 29 attached to a hydraulic clutch 30 from the outside. Hoses they have separate channels for the inner tube and the outer tube. Hydraulic clutch can also be used to support the spring 23.

It is important that plastic components remain separated until they reach the connection with the internal channel 9 truss rod 3, and so they are mixed only in anchor rod in stationary mixer, placed in it. Thus, the response time for curing plastic components starts at the same time as the filling time to fill drilled holes, including the internal channel truss rod. Therefore the time needed for filling and reaction time can be accurately reconciled with one another, regulating the filling ratio of plastic components.
