Abstract

Use: in the construction of flexible metal corrugated pipes under the embankment. SUMMARY OF THE INVENTION: The device consists of a pipe placed on the base 1 and adjacent at the level of a horizontal diameter on the outside of the bars 3. The bars are covered with struts 4, the lower ends of which are connected by horizontal bars 5. The upper ends of the struts are made with broadened 6, located on level top of the pipe. The bottom of the widening is located not less than 0.9 of the pipe diameter from the base. 1 il.

Description

Its side of the flexible pipe at the level of its $ 1 mi occurs within the prescribed limits.

horizontal diameter, and the racks enclosing them, the lower ends of which are interconnected by horizontal drafts, are made with broadening at the top of the pipe, with the bottom 20 of these broadening located at a height from the base of not less than 0.9 of the pipe diameter.

With this arrangement, the culvert under the embankment of the stand with 25 stresses made at the level of the top of the pipe has the ability to move in the ground under the influence of the thrust from the flexible pipe. Accordingly, it can occur within the prescribed limits 30 and the movement of the side walls of the pipe. As a result, the spread of the flexible pipe is perceived partially by the longitudinal bars of the reinforcing system and partly due to the passive lateral rejection of the embankment soil in the medium-height zone of the pipe’s cross-section where the largest horizontal displacements of its walls occur. The forces perceived by the longitudinal bars are transmitted to the horizontal bars and to the broadening, respectively, at the lower and upper ends of the uprights. Efforts from broadening on the racks B1 were taken and the queue is perceived by passive resistance of the soil over the broadening. At the same time, the soil of the embankment is involved in efficient work in areas where horizontal displacement of the pipe walls is absent, since the broadening on the JJQ stands is made at the top of the pipe, and the lower broadening is located at a height from the base of at least 0.9 pipe diameter, t. e. the broadening is located above the zones, in which horizontal wall displacements take place. pipes. By virtue of this, the voids that may be formed beyond the broadenings during their movements have no practical effect.

increasing and twisting the deformations of the flexible pipe. As a result, the vertical pressure of the soil on it decreases, which also increases the reliability of the culvert, and reduces its consumption of materials.

On the drain there is a water-passage-1- construction under the embankment, transverse: section.

The water supply structure contains a flexible pipe-1 with a diameter of 1 mounted on the base 2, and a system of reinforcing elements placed outside the contour of the pipe t and consisting of longitudinal bars 3 adjacent to the outer side of the flexible pipe 1 at the level of its horizontal diameter and covering their racks 4, the lower ends of which are interconnected by horizontal bars 5. Racks 4 are made with a width of 6 at the level of the top of the pipe, with the bottom of the width

6 is located at a height from the base 2 of not less than 0.9 of the diameter of the pipe 1. The flexible pipe 1 with a system of reinforcing elements is located under the embankment 7,

The culvert under the embankment is made as follows.

Base 2 is prepared, for example, by planning it with a bulldozer and flexible pipe 1 is mounted on it. Horizontal pipes are placed on base 2 before or after installation of Pipe 1 5. Embankment soil is made by tamping

7 Subsidiary quarters of the pipe 1. Install the pillars 4 with the widening 6 and the longitudinal bars 3. The widening 6 can be made in the form of longitudinal boards and pre-attached to the posts 4. The longitudinal bars 3 can be pre-attached to the uprights 4 or to the pipe 1. After installation of the posts 4, their ends in each section are interconnected by horizontal thrusts 5. Then, a embankment roll 7 is layered with compaction.

Culvert construction under the mound works as follows.

Flexible pipe t pbd impact of the load from the embankment of the 7th stratification to flatten with increasing horizontal size. The thrust forces from flexible J pipe 1 are transferred to the longitudinal bars 3, and from them to horizontal rods 5 and broadening 6, respectively, at the lower and upper ends of the pillars 4. The lower ends of the racks 4 held by the horizontal rods 5. remain in place. The upper ends of the pillars 4, overcoming the resistance of the passive resistance of the soil of the embankment 7 behind the widening 6, move away from the flexible pipe 1. Accordingly, the longitudinal bars 3 and the side walls of the flexible pipe 1 move towards the embankment 7, causing appearance in the area of these movements passive soil repulse, which is also included in the work on the perception of thrust from the flexible pipe 1. At the same time, the

1, which leads to a decrease in soil pressure on the pipe.

The technical and economic effect from the application of the proposed culvert under the embankment consists in improving the conditions and increasing the reliability of the culvert under the embankment in reducing its material intensity. .

The faucet under the embankment contains a flexible pipe mounted on the base and a system of reinforcing elements placed outside the pipe contour and consisting of longitudinal bars adjacent to the outer side of the flexible pipe. the level of its horizontal diameter g and the poles that stand on them, the ends of which are interconnected by horizontal lines: m, g, h t and h @ u with the fact that, in order to increase the reliability in operation and to increase materials consumption, the racks are made from wider levels on the level Erhan pipe, the bottom ushirenmy located on snbvaky You are a cell of the order of at least 0.9
