RU193391U1 - DOUBLE WALL ELEMENT - Google Patents

Abstract

The utility model relates to hydraulic engineering and can be used in the construction of piers, locks, dams, dock structures, mooring bollards, bridge supports; construction of retaining walls; shore protection, water intake and drainage facilities; sewage treatment plants, collectors, tunnels, underground structures, ring closed and open structures, fences; when arranging pits, slopes, foundations, walls of trenches. The utility model is used to create walls with large moments of inertia, in particular for replacing sheet pile walls with large diameters (up to 3000 mm). It can also be used to deter slopes from slipping and instead of some anchor rods (to reduce the diameter and number of anchor rods until they are completely abandoned). The technical result of the claimed utility model consists in the possibility of replacing the U-shaped profile with prefabricated T-beams, consisting of separate flat sheets welded together, which simplifies the process of transportation and storage of assembly elements of the sheet pile wall. At the same time, the utility model retains the ability to form a strong straight wall or a wall with a bend. The specified technical result is achieved due to the fact that the declared sheet pile wall element made of a welded sheet pile, consisting of a profile, to the walls of which in the area of its ends there is a sheet pile profile with locks at the ends, where the sheet pile consists of a T-profile, characterized in that the T-profile is made in the form of an I-beam and has a small and a large shelf, the tongue is fixed with its outer part of the shelf to the small shelf of the I-beam by a welded joint so that the welded joints are located in the zone of separation of direct contact the dowel shelves from the small flange of the I-beam, and the I-beam itself is formed by joining separate sheets of the beam and the shelves with each other by a welded joint, and additional shelves are made between the small and large shelves of the I-beam on the beam on opposite sides of it, which are fixed to the beam by a welded joint.

The utility model is used to create walls with large moments of inertia, in particular for replacing sheet pile walls with large diameters (up to 3000 mm). It can also be used to deter slopes from slipping and instead of some anchor rods (to reduce the diameter and number of anchor rods until they are completely abandoned).

The closest analogue is the sheet pile wall element (patent RU 180747U; publ.: 06/22/2018.), Made of a welded sheet pile, consisting of a profile, to the walls of which a sheet pile profile with locks at the ends is fixed, characterized in that the sheet pile consists of a T-box, having a U-shaped cross-sectional profile, and a trough-like sheet pile is used as the sheet pile profile, the latter being fixed to the walls of the T-box in the region of its ends with the outer side of the flanges.

This wall provides the possibility of using a trough-like sheet pile without using a T-beam, provides the ability to form a strong straight wall or wall with a bend, and accelerates the process of forming a sheet pile.

The technical problem of the prototype is the need to use a U-shaped profile, which is complex and expensive to transport because of its size.

The objective of the claimed utility model is to eliminate the disadvantages of the prototype while maintaining the ability to form a strong straight wall or a wall with a bend, the ability to replace the U-shaped profile with T-beams, which are formed in place by welding individual flat sheets, which simplifies the process of transportation and storage of assembly elements of the tongue wall .

The technical result of the claimed utility model consists in the possibility of replacing the U-shaped profile with prefabricated T-beams, consisting of separate flat sheets welded together, which simplifies the process of transportation and storage of assembly elements of the tongue wall. In this case, the utility model retains the ability to form a strong straight wall or a wall with a bend.

The specified technical result is achieved due to the fact that the declared sheet pile wall element made of a welded sheet pile, consisting of a profile, to the walls of which in the area of its ends there is a sheet pile profile with locks at the ends, where the sheet pile consists of a T-profile, characterized in that the T-profile is made in the form of an I-beam and has a small and a large shelf, the tongue is fixed with its outer part of the shelf to the small shelf of the I-beam by a welded joint so that the welded joints are located in the zone of separation of direct contact the dowel shelves from the small flange of the I-beam, and the I-beam itself is formed by joining separate sheets of the beam and shelves with each other by a welded joint, and additional shelves are made between the small and large shelves of the I-beam on the beam on opposite sides of it, which are fixed to the beam by a welded joint.

It is permissible that a trough-like tongue is used as a sheet pile profile. Brief Description of the Drawings

Utility Model Implementation

The tongue-and-groove wall element is made of a welded tongue-and-groove pile consisting of a profile, to the walls of which a tongue-and-groove profile with locks at the ends is fixed to the walls of its ends. The sheet pile itself consists of a T-profile.

As a tongue-and-groove profile, for example, a trough-like sheet pile or any other sheet pile with locks at the ends can be used.

New is that (see Fig. 1) the T-profile is made in the form of an I-beam and has a small and a large shelf, and the tongue is fixed with its outer part of the shelf 1 to the small shelf 5 of the I-beam by a welded joint 6 in the area of separation of the direct contact of the tongue 1 from the tongue 1 shelves 5 I-beams. This makes it possible to replace the U-shaped profile with prefabricated T-beams, consisting of separate flat sheets welded together, which simplifies the process of transportation and storage of assembly elements of the sheet pile wall.

An I-beam is formed by a welded joint of individual elements of the beam 4 and small 5 and large 7 shelves. This simplifies the process of transporting and storing the assembly elements of the sheet pile wall.

To strengthen the strength, the I-beam has additional shelves 8, which are fixed between the small 5 and the big 7 shelves on the beam 4 by a welded joint 6 on opposite sides of it.

The welded joints 6 can be continuous (as shown in Fig. 2), and alternating in a checkerboard pattern (as shown in Fig. 3).

In this case, the utility model retains the ability to form a strong straight wall (see Fig. 4) or a wall with a bend (see Fig. 5) by connecting such modules with locks 3 located on the flanges 2, regardless of whether an additional double tee is used or not .
