Abstract

-TUBE BULK PIPE, containing walls installed on the base and joined to the arch, from seams that are separated from the specified plate, in order to reduce material intensity and increase reliability in operation, it is provided with fragile plates installed vertically between the soles of the walls and the base, with the plates bounded by the plates, through one space filled with plastic material and communicating with each other by channels that are made in the wall.

Description

The invention relates to the construction of culverts, in particular, under high embankments.

A well-known pipe under the embankment, containing walls installed on the base of the wall and walls combined with the roof, separated from the indicated plnty by seams I.

A disadvantage of the known pipe is the high consumption of materials associated with overloading the pipe from the pressure of the high embankment.

The aim of the invention is to reduce material consumption and increase reliability.

This goal is achieved by the fact that the pipe under the embankment, containing bottom walls installed on the base and jointed with the arch walls, separated from the specified plate with seams, is provided with fragile plates installed vertically between the wall soles and the base, while the confined spaces bounded by the plates are filled with plastic material and communicated among themselves channels that are made in the wall.

FIG. 1 shows the proposed pipe, cross-section; in fig. 2 shows section A-A in FIG. one.

The pipe under the embankment contains a bottom plate 1 and 2 walls combined with the arch

L- / 1

3, separated from the plate by seams 4. The pipe is provided with brittle plates 5, installed vertically between the bottom of the walls of the 3 r axles 6. Formed - closed spaces 7 are laminated through plastics 5 through one plastic material 8 and communicated among themselves by channels 9, which are; made in the wall.

The design works as follows.

0 As the embankment is erected, the plates 5 are destroyed and the pipe gradually settles into confined spaces 7, while the plastic material 8 is squeezed out from the spaces filled by it into the adjacent — hollow ones, forming a continuous layer under the walls of the pipe along the entire base. In the embankment above the pipe, an area of unfrozen soil is formed, respectively, the pressure on the pipe decreases. The formed layer of plastic material 8 on the basis of 6 prevents the pipe from transmitting forces from the base, in case of its formation, heterogeneity, seismic movements, etc.

The proposed design provides an effective pipe unloading from the top

5 tical pressure and reduction of its material capacity, possesses increased operational reliability.
