Description

The utility model relates to the field of construction, namely to sheet piles used in the construction of sheet pile walls of sea and river piers, as well as retaining walls constructed in water-saturated soils.

One of the main tasks to be solved during the construction of facilities for this purpose is the high anti-filtration reliability of structures, which ensures the tightness of the joints of sheet piles. In construction practice, this problem is solved by filling the gaps in the tongue-and-groove joints with a sealing compound, welding the elements of the locking joint, connecting them with glue, filling the gaps with soil, etc.

Known, for example: retaining wall, sealed with mortar based on concrete or concrete (application RU No. 2001128073); a wall made by a method in which the tongue and groove locks are welded together using a welding electrode (application RU No. 2002127801) and others. These structures are tight and soilproof, however, the construction requires a lot of labor and material costs.

One of the less expensive areas for ensuring soil and water tightness of sheet pile walls is the creation of structures in which tightness is ensured by structural elements of the locking connection of sheet piles.

Known sheet piles connected to the sheet pile wall using a lock with a metal sealing element (patent RU No. 2368723). The design of the lock allows you to improve the quality of assembly of the sheet pile wall, as well as its soil and water resistance. A disadvantage of the known tongue-and-groove connection is the complexity of manufacture.

The closest analogue of the proposed technical solution for the technical nature and purpose is a sheet pile according to US Pat. RF №115372, IPC E02D 5/08, publ. 04/27/2012. The prototype device is a plastic sheet pile, consisting of a housing with lateral edges, one of which is made in the form of a female U-shaped locking element (tongue and groove), and the second in the form of a T-shaped male locking member (tongue and groove) . The lateral edges with male and female form provide a connection with the corresponding lateral edge with female and male form of a similar sheet pile. A continuous wall of said sheet piles forms a sheet piling. The disadvantage of the prototype is the soil and water permeability of the connection due to the lack of tightness of the structure caused by the presence of a gap between the tongue and groove tongue and groove tongue.

From the point of view of ensuring soil and water tightness, it would be advisable to reduce the size of the grip cavity in which the protrusion of the adjacent pile is placed in order to minimize gaps. However, this would impair assembly conditions.

The technical problem solved by this utility model is to maintain the conditions for the unimpeded assembly of sheet piles and their reliable connection while ensuring the tightness of the connection.

To solve this problem, the following set of essential features is used: in a sheet pile, which, like the prototype, consists of a body and side edges, one of which is supplemented with a tongue-and-groove grip with an open covering cavity, and the other is a tongue-and-groove protrusion with a covered surface, made with the possibility of castle connections, respectively, with the tongue and groove tongue and groove adjacent piles, in contrast to the prototype covering the tongue of the tongue and groove tongue and groove tongue in cross section have f the shape of the rhombus with a truncated apex, while the tongue of the tongue mates with the lateral edge of the pile in the section of truncation of the top of the rhombus, and the free ends of the tongue-and-groove grip are made flat in the area of their coverage of the lateral edge of the tongue of the tongue of the adjacent pile.

In the claimed design, between the interacting surfaces of the elements providing the locking connection of adjacent piles, a gap is created for unimpeded immersion of the piles, which overlaps during assembly and loading of piles that experience bending (bending) or compressive (compressive) forces under load. As a result of the indicated forces, the tongue and groove of the pile with two adjacent faces will come into contact with the two faces of the inner surface of the tongue and groove of the adjacent pile. The piles will be closed by the lateral edges and, due to the tight linear fit of the contacting surfaces, form a continuous sealed wall, providing water and soil impermeability of the connection. In this case, in general, as indicated above, the size of the gap in the castle connection will not decrease. In turn, the interaction of the supporting sections of the tongue-and-groove protrusion in the rhombus-edge zone with the thrust portions of the covering surface of the tongue-and-groove grip will ensure reliable retention of the protrusion in the grip, preventing the protrusion from slipping out of the engagement with the grip.

To ensure a more uniform load distribution in the protrusion-grip connection, the rhombus angles between adjacent sides are equal to 90 °

To ensure a more uniform distribution of stress in the connection "protrusion - capture" the tops of the rhombus are in the form of a semicircle.

The claimed design allows the connection of sheet piles with any configuration of the body: Z / S / Ω / -shaped, flat, trough-shaped, tubular, and other profiles.

The proposed technical solution gives a particularly good result when used in products made of PVC (polyvinyl chloride) and composite materials, but it can also be used in steel sheet piles.

Comparison of the proposed device and the prototype showed that the solution to the problem of ensuring the smooth assembly of sheet piles and their reliable connection while ensuring the tightness of the joint is solved as a result of a new set of features, which proves that the proposed utility model meets the patentability criterion of “novelty”.

The essence of the utility model is illustrated by the drawing, where in FIG. 1. presents a pile of Z-shaped with elements of the castle connection;

in FIG. 2. - knot of the castle connection with the right angles of the rhombus;

in FIG. 3. - knot of castle connection with semicircular tops of a rhombus.

The sheet pile shown in FIG. 1, has a Z-shaped housing, but, as indicated above, the housing may have a Z / S / Ω / -shaped, flat, trough-shaped, tubular, and other profile. A grip 1 is made on the right lateral edge of the pile, and a protrusion 2 on the left edge. The protrusion 2 has a cross-section in the form of a rhombus with a vertex truncated in the zone 3 of the interface between the protrusion and the edge. The grip cavity 1 is bounded by a female surface and, in cross section, also has a diamond shape with a truncated apex. The protrusion and capture of adjacent piles form a castle connection (Fig. 2, 3). In the manufacture of piles between the locking elements, a gap is provided, which is compensated for by the load of the pile structure. The tightness of the connection is ensured due to the fact that under the action of bending (bending) forces on the wall of the structure, the protrusion of the pile with two adjacent faces will come into contact with two faces of the tongue-and-groove grip of the adjacent pile. As can be seen from FIG. 2, the elements close along line 5 and thereby form a continuous sealed wall. The reliability of the retention of elements during compressive (expanding) forces is ensured by the interaction of the supporting sections of the tongue-and-groove protrusion in the rhombus-edge zone with the thrust sections of the covering surface of the tongue-and-groove grip. In this interaction, 2 faces of each element also participate, which increases the area of contacting surfaces and thereby eliminates the possibility of the protrusion slipping out of engagement with the grip. This is also facilitated by a sufficiently tight grip of the protrusion by the flat free ends of the connection element 1.

The proposed device has simplicity and manufacturability in the manufacture, creates the conditions for the smooth assembly of sheet piles by eliminating jamming in the castle connection. It has high water and soil impermeability and reliable connections.

The device was developed by specialists of FSBEI HE GUMRF and Rodnie Bereg LLC as part of a research group. Calculations were made that showed the possibility of using the device for connecting sheet piles with any configuration of the body: Z / S / Ω / -shaped, flat, trough-shaped, tubular, and other profiles.

The above provision allows us to conclude that the utility model meets the criterion of "industrial applicability".
