SU1427041A1 - Apparatus for concreting solid ferroconcrete pipeline - Google Patents

Abstract

The invention relates to construction and can be used in the construction of reinforced concrete pipelines. The purpose of the invention is to improve the wear resistance of the pipeline being constructed by installing a facing tile material in their tray part. For this, the facing material 10 is placed on the pallet 4 through the window 11 and is fixed in the design position by the latch 5. Then a concrete mix is fed into the space between the core 7 and the outer sections 9 and pressed with the help of the ring 1. In this case the facing tile 10 is attached to the body pipe and forms its tray part. 3 il. o. s 1 13 3 2 L / W with

The invention relates to construction and can be used in the construction of water discharge pipes on rivers, for lining construction and operational tunnels. ; The aim of the invention is to increase the wear resistance of the constructed (pipeline).

FIG. 1 shows a device

Lengthwise cut; FIG. 2 is a section A-A in FIG. one; in fig. 3 - scheme of the device.

The device consists of a pressing ring 1 and a stop ring 2 movably connected by means of hydraulic cylinders 3, a pallet 4 connected with a stop ring 2, a clamp 5 connected movably to the stop ring 2. 6 can be moved along the pro- longitudinal axis of the formwork over the pallet 4. The pressing ring 1 has a cut-out in the lower part for moving the pallet 4. The core 7 is rigidly connected to the stop ring 2 and the pipeline 8 being built is enclosed in the outer sections 9.

A window 11 is provided for feeding the facing tiles 10 to the pallet 4.

The device works as follows.

Monolithic reinforced concrete pipeline 8 erected on supports 12 Armo

the frame 13 and the outer sections 9 are installed in advance on the supports 12j and the pipeline is concreted by the flow-cyclical method with rings 14. In the initial position, before the concreting of each entry, the facing tile 10 is placed on the pallet 4 through the window 11 and pressed tightly against each other and to previously concreted tiles retainer 5 using a hydraulic cylinder 6.

Concrete entry 14 is laid using a concrete pump and pressed with a ring 1. Retaining ring 2 with

the core 7 and the pallet 4 connected with it are moved relative to the compression ring 1 by means of hydraulic cylinders 3 with the output of the pallet 4 beyond the concrete inlet 14. At the same time, the facing tiles 10 with the inner surface are pressed to the core 7 and pressed from the outside by holding concrete from the end of the latch 5 and the hydraulic cylinders 6, and the pallet 4 slides with the cut-out of the pressing ring 1.

Then the pressing ring 1 is retracted from the end of the manufactured section of the pipeline 8 by means of hydraulic cylinders 3 to the initial position for concreting the next entry. The pressing ring 1 slides smoothly along the pallet 4 with the facing tiles 10 laid along it. At the same time, the pallet 4 with the tiles 10 remains in the subframe space formed by the end face of the manufactured pipeline 8, the pressing ring 1, the core 7 and the outer sections 9 of the formwork.
