Abstract

FIELD: construction.

SUBSTANCE: structure consists of sections 2, each of which contains a reinforcement framework 3 corresponding to the cross-section of the portion 1 to be reconstructed. A profile plastic tape 4 and a profile connecting device 11 are wound in a spiral to the framework 3. The profile of the tape 4 and the connecting device is shown in the figures. To implement the method, the geometric characteristics of the portion 1, the dimensions of the framework 3, the number of sections 2 in the structure are determined. On the shore platform 20, the frameworks 3 are assembled. Coaxially with the portion 1, a mounting-docking platform 21 is installed, on which mounting operations are carried out step by step with successive movement of the frameworks 3 to it from the platform 20. On each framework 3, the tape 4 and the device 11 forming the section 2 with the framework 3 are successively spirally wound. According to the first version, the structure in the form of a pipe 19 is formed directly in the portion 1 from its end to the beginning, for which, after adjustment, each two sections 2 are docked, disconnected, and then, by means of the winch 22, each section 2 is installed at the end of the portion 1 and rigidly connected. Alternatively, after adjustment, the sections 2 are docked and rigidly connected, forming a structure in the form of a pipe 19 directly on the platform 21, and by means of the winch 22 is mounted on the station 1. For each version, the volume between the inner surface of the portion 1 and the outer surface of the pipe 19 is filled with a polymer-cement composition.

EFFECT: increasing the structure strength, ensuring the monolithic character of the structure and the portion to be reconstructed.

This technical solution was taken as the closest analogue of this group of inventions.

The closest analogue method and pipe lining means make it very simple and cheap to perform lining of a worn-out sewer pipe in a spiral wound lining pipe with a diameter close to the diameter of the pipe to be lined.

The closest analogue method eliminates the need to expand the wound lining pipe after it is fed into the lined pipe to a larger diameter close to the diameter of the latter.

However, the shape of the spiral coil and the cross section of the wound facing pipe depends on the structural design of the winding machine and its location, which negatively affects the quality of the wound facing pipe and on the installation operations during the closest analogue and limits the possibility of its implementation.

The basis of this group of inventions is the solution of the problem, which allows to improve the quality of the internal protection of culvert systems and the strength of the structure, to ensure the solidity of the structure and the site being restored, to expand the possibilities of using the structure, carrying out installation work and performing restoration work.

The technical result of the invention consists in carrying out work on a restored section of any length with various cross-sectional shapes of watercourses, in forming a structure of rigidly connected “n” sections from the end of the restored section to its beginning (Option 1) and outside the restored section (Option 2), in extension the possibility of installation work, regardless of the size of the restored section, in ensuring the hydrostability of the structure, in creating a monolithic structure and the restored section at Using the high-polymer-prochnostnogo composition and in enhancing the ability culvert systems due to design features of the plastic profiles and tape connector.

According to the group of inventions, this problem is solved due to the fact that the design for the internal protection of culverts, including areas requiring restoration work, contains a pipe made of plastic material. A pipe made of plastic material is formed by winding a spiral of plastic tape.

The design consists of "n" sections, each of which contains a reinforcing cage with a geometric shape corresponding to the cross section of the restored section, on which a profile plastic tape and a profile connecting device are wound in a spiral.

Profile plastic tape has a base, internal longitudinal profile elements, the vertical shelves of which are perpendicular to the base, and external longitudinal elements with a connector made of profiles.

The profile connecting device comprises a compensator in the form of an elastic membrane and a base made of two bases, which are connected in the center by a profile and along the edges of which are double profiles with the possibility of use as primary and secondary locking elements.

Primary and secondary locking elements have the ability to interact with the connectors of the profiles of the outer longitudinal elements and provide a rigid connection "n" sections to each other, forming a design in the form of a single plastic pipe.

The inner surface of a single plastic pipe is formed by the base of the profile of the plastic tape and the two bases of the profile connecting device.

The outer surface of a single plastic pipe is formed by the internal longitudinal profile elements of the plastic tape and the membranes of the profile connecting device.

In addition, the internal longitudinal elements of the plastic tape are made of a T-shaped profile.

In addition, holes are made on the vertical shelves of the T-profile.

In addition, the holes can be made triangular in shape, forming a truss.

In addition, the holes can be made round in shape and are located symmetrically in one row.

According to the group of inventions (Option 1), this problem is solved due to the fact that the method of carrying out restoration work with a structure for the internal protection of culverts, performed according to p. 1-8, consists in carrying out the preparatory phase of restoration work, assembling the structure and carrying out installation work with her.

Determine the geometric characteristics of the restored section, the dimensions of the reinforcing cage, the number of sections.

On the coastal platform, “n” reinforcing cages are assembled corresponding to the number of “n” sections.

An assembly and docking platform is installed coaxially with the area being restored, on which stage-by-stage installation operations are carried out with successive movement of reinforcing cages onto it from the coastal platform.

On each reinforcing cage, a plastic profile tape and a profile connecting device are sequentially spirally wound, forming a section with the reinforcing frame.

The ends of the winding profiles are adjusted for each of the two sections so that the geometric parameters of the wound profile plastic tape with the profile connecting device at the end of the section correspond to the geometric parameters of the wound plastic tape with the profile connecting device at the beginning of the next section.

After that, every two sections are joined, and then disconnected, and one of the sections is installed by means of a winch at the end of the restored section.

The stages of assembly and installation work are repeated, forming a design in the form of a single plastic pipe from rigidly connected sections directly on the restored section from its end to the beginning.

Then the volume between the inner surface of the restored section and the outer surface of a single plastic pipe is filled with a polymer-cement composition of the brand with a water resistance of at least W12 with a compressive strength of 30 MPa and a tensile strength of 10 MPa after 24 hours.

The control of volume filling is carried out by metering devices.

According to the group of inventions (Option 2), this problem is solved due to the fact that the method of carrying out restoration work with the structure for the internal protection of culverts, performed according to p. 1-8, consists in the preparatory phase of the restoration work, assembly of the structure and installation work with her.

The method according to Option 2 differs from the method according to Option 1: after fitting the wound sections, they are joined directly on the mounting and docking platform, forming a structure in the form of a single plastic pipe, after which a single plastic pipe is installed on the site to be restored using a winch.

The applicants did not identify sources containing information on technical solutions identical to this group of inventions, which allows us to conclude that it meets the criterion of "novelty."

Due to the implementation of the distinguishing features of the group of inventions (together with the features indicated in the restrictive part of the formula), important new properties of the object are achieved.

The construction of the internal and external profile elements of the plastic tape and the profile connecting device provides a tight connection when they are wound in each of the "n" sections and the rigid connection of the "n" sections with each other with the formation of a single plastic pipe improves the quality of the internal protection of culvert systems.

The construction of the "n" sections, each of which contains a reinforcing cage, on which a plastic tape with internal and external longitudinal elements and a profile connecting device are wound in a spiral and the formation of a single plastic pipe from them ensures work on the restored section of any length with various shapes cross-sections of watercourses, which expands the possibilities of carrying out restoration work.

Formation of the structure from rigidly connected “n” sections from the end of the restored section to its beginning (Option 1) and outside the restored section (Option 2) expands the possibilities of installation work regardless of the dimensions of the restored section and expands the possibilities of using the structure.

The ability to make triangular or round holes on vertical shelves of the T-shaped profile of the plastic tape allows you to expand the use of the structure and reduce weight.

The formation of the inner surface of a single plastic pipe with the bases of the profiles of the plastic tape and the connecting device increases the throughput of the systems.

The formation of the outer surface of a single plastic pipe by the internal and external longitudinal profile elements of the plastic tape ensures the strength and security of the structure.

The presence on the outer surface of a single plastic pipe of membranes of a profile connecting device provides a “locking” membrane effect that prevents the entry of contaminated moisture into the soil and an “open” membrane effect in which the membranes are a kind of internal hydraulic pressure valve to release accumulated moisture and prevent delamination from the internal hydraulic pressure of the restored section and the new single plastic pipe, which improves the quality of internal protection ny systems.

Filling the volume between the inner surface of the restored section and the outer surface of the plastic pipe with a polymer-cement composition ensures the solidity of the connection between the structure and the restored section.

The applicants are not aware of any publications that would contain information on the influence of the distinguishing features of the group of inventions on the achieved technical result. In this regard, according to the applicants, it can be concluded that the claimed technical solutions meet the criterion of "inventive step".
