RU113808U1 - POLYMER CONTAINER BALLASTING DEVICE - Google Patents

Abstract

A polymer-container ballasting device containing two containers placed on both sides of the pipeline and filled with soil, made of a single panel applied to the pipeline and end walls sewn to it, stiffening frames, consisting of longitudinal, transverse elements located along the pipeline, two upper and two lower power zones connected by eyes, respectively, with the upper and lower longitudinal elements of the stiffness frames, while the lower power zones are located under a single panel m, the end walls of the containers are suspended on the upper power belts cover frame rigidity on the part of its cross members and formed with slits or notches, through which the transverse stiffeners of the framework for connection to the lower longitudinal elements.

Description

The technical field to which the utility model relates.

The utility model relates to equipment used for laying pipes in the soil, more specifically to ballasting devices for pipelines used when laying pipes in flooded trenches and in swamps.

State of the art

Known polymer-container ballasting devices described in RU 45498 and RU 2266457, containing two containers placed on both sides of the pipeline and filled with soil, made of a single panel applied to the pipeline and end walls sewn thereto, power belts and stiffeners, consisting of longitudinal (located along the pipeline) and transverse elements, These well-known polymer-container ballasting devices are prototypes of the claimed device. Their disadvantage is the uneven distribution of the load on a single panel forming containers, because stiffness frames are installed directly on it. The disadvantage is that the end walls of the tanks are sewn to the upper power zones. This also leads to an uneven distribution of load on the power zones, and on a single panel.

Utility Model Disclosure

The technical result achieved in the claimed utility model is to reduce the load on a single panel forming containers, through the use of lower power belts located under a single panel, and hanging the end walls of containers on the upper power belts with the possibility of displacement along them. At the same time, due to the end walls of the containers covering the stiffness frames, an increase in the volume of containers is achieved. Thus, more fully used the strength capabilities of the device.

The specified technical result is achieved in a polymer-container ballasting device, containing two containers placed on both sides of the pipeline and filled with soil, made of a single panel applied to the pipeline and end walls sewn to it, stiffening frames, consisting of longitudinal (located along the pipeline) and transverse elements, as well as two upper and two lower power belts connected by eyes, respectively, with the upper and lower longitudinal elements of the stiffness frames, while the lower power belts are located under a single panel, and the upper power belts are above a single panel, the end walls of the containers are suspended on the upper power belts, cover the stiffening frame from the side of its transverse elements and are made with cuts or cuts through which the transverse elements of the stiffening frames pass for connection with upper and lower longitudinal elements. The end walls of the containers can be made with sleeves into which the upper power belts are threaded.

Brief Description of the Drawings

Figure 2 presents a top view of the device.

Utility Model Implementation

Figure 1 shows the pipe 1 of the pipeline, on which a single sheet 2 is laid, better shown in figure 2, and below it a lower power belt 3. The tanks, on both sides of the pipe 1, are formed by a single sheet 2 and end walls 4. The upper the power belt 5 is sewn to a single panel 2 together with the lower power belt 3 only in the upper part of a single panel superimposed on the pipe. The end walls 4 are made with sleeves, dressed on the upper power zones 5.

On opposite sides of the pipeline, stiffening frames are also installed, consisting of each of the lower 6 and upper 7 longitudinal elements and two transverse elements 8. The lower longitudinal elements 6 of each frame are installed in the eyes of the lower power zones 3, and the upper longitudinal elements 7 are held in the eyes of the upper power zones 5.

In the form of the device shown in figure 2 shows a single panel 2, fitting the pipe and forming the bottom and the wall of each of two containers located on opposite sides of the pipe. The edges of a single panel are bent, forming sleeves, dressed on the upper longitudinal elements 7.

The transverse elements 8, as shown in figure 1 and figure 2, do not prevent the "inflating" of the end walls of the tanks when filling them with soil. For this, the transverse elements 8 are located inside the containers. In the end walls 4, cuts 9 are provided for the transverse elements 8 near their connection with the lower longitudinal elements 6. The transverse elements 8, when assembling the polymer-container ballasting device, are installed in the cuts 9 of the end walls 4.

The single panel 2 and the end walls are made of rolled synthetic material, for example, polyamide, polypropylene or polyester.

The stiffness frame is made of metal elements, and is assembled and installed immediately before installing the polymer-container ballasting device and filling it with soil. Pipeline weights are installed on pipelines with diameters from 377 mm to 1420 mm.
