Description

I

The invention relates to the construction of pipes for various purposes, located under the embankment, and structures, in particular, under high embankments.

The aim of the invention is to improve the operational reliability of the pipe and simplify the design.

Fig, I shows a pipe, cross section; in fig. 2 — node I in FIG. one.

The pipe under the embankment contains a reinforced concrete structure made of composite upper 1 and lower 2 parts, between adjacent ends of which there are Z o6pa3Hbie seams 3. Outwardly half of the joint cavity is sealed with viscous material 4, for example bitumen, in the inner half 5 of the joint cavity 3 are placed temporary vertical locking elements 6; Viscous material 4 in the outer half of the seam 3 is connected by channels 7 with the inner cavity of the seam 5 and the cavity of the pipe 8. The pipe is reinforced with reinforcement 9 and is located in embankment 10 on the base 11.

The pipe is made in the following way.

On the prepared base 11, the lower reinforced concrete was erected.

Partly 2 pipes and form a can, aly 7 in its walls. 7. A viscous material is placed on the protrusion of the lower part of the pipe, blocking

fi version of channels 7, for example, plastic wrap (not shown). Vertical reinforcement bars 6 and the rest of reinforcement 9 and concrete are mounted on the ledge of the lower part of the pipe.

 About niruit the upper part of the I pipe, forming the internal cavity 5 of the seam 3. Fill the pipe with the soil of the body of the mound W to a predetermined value. Then cut off the reinforcing bars 6 in the cavity

15 seam 3 and continue to pour the embankment 10 to the design mark. At the same time, the viscous material 4 begins to be squeezed through the channels 7 into the internal cavity 5 of the seam 3, and from there into the cavity

20 8 pipe, and the upper part 1 of the pipe moves down, i.e. it begins to work as a flexible pipe, and the vertical pressure on the pipe does not increase.

The lack of channels and plugs on channels 7, as well as cavity-forming agents, significantly simplifies the design of the pipe and increases its operational reliability.
