Description

The invention relates to the field of construction of hydraulic structures using metal sheet piles or panels, combined into a continuous sheet pile wall driven into the ground using special locks.

The purpose of sheet piles or panels of any design is to create a sheet pile wall on a construction site that combines a number of sheet piles or panels successively driven into the ground. Sheet pile walls are used in the construction of hydraulic structures for various purposes. To create sheet pile walls, piles or panels must have locks to ensure their strong, tight and reliable connection. The configuration of the sheet pile wall can be varied, and the design of the locks must meet the specified requirements.

A welded lock is known (patent RU 2103442 C1, IPC E02D 5/08, publ. 01/27/98) for combining tongue-and-groove panels, including a holder formed by an angular profile welded to the tongue-and-groove panel with the edge of one of the shelves at an acute angle with an inclination towards the free edge consoles and a connecting cam inserted into the cavity of the holder, welded to another tongue-and-groove panel.

This lock provides a strong and tight connection, it is used to combine tongue-and-groove panels of open profile. It is not possible to apply it to combine sheet piles of a closed profile. In addition, the design of the lock does not allow the relative angular movement of adjacent tongue-and-groove panels, therefore, to change the configuration of the tongue-and-groove wall in the plan, when, in contrast to the rectilinear direction, the neighboring panels are required to be deflected by a certain angle relative to each other, it is necessary to use special tongue-and-groove panels.

The closest in design is a welded tongue-and-groove lock (utility model RU 82461 U1, E02D 5/08, published April 27, 2009), formed from two elements, one of which is made in the form of an angular profile fixed to the generatrix of the sheet pile the edge of one of the shelves, while the angular profile is welded to the longitudinal surface of the sheet pile at an acute angle with an inclination towards the edge of the free shelf, the sheet pile is made in the form of a closed profile pile, the sheet pile lock consists of two identical elements in the form of standard corner profiles, which are fixed on two adjacent sheet piles parallel to the longitudinal axis of the sheet pile with a gap between the outer mating angle of the shelves of the standard corner profile and the outer surface of the adjacent sheet pile, while one standard profile is mounted on the sheet pile at a certain angle to the outer surface of the sheet pile piles in its cross section, and the second standard corner profile is mounted on the adjacent sheet piling mirror to the first and at the same angle.

This design of the lock in application for combining sheet piles, the dimensions of which do not allow significant angular relative movement, ensures their full and tight connection, the contact shelves of the mating corner elements of the lock are parallel to each other. Deviations from the straightness of the sheet pile wall configuration in terms of are achieved by using special sheet piles with an appropriate arrangement of locking elements along the generatrix of the pile surface. If the design of adjacent piles, and even more so of open-profile panels, allows their relative angular movement in the locking part, then the strength and density of the tongue and groove joints with an increase in the turning angle will decrease until the joint is broken and therefore the use of locks of this design in the described case is impossible. The inability to create a sheet pile wall of various configurations in terms of design due to the design features of the considered lock options makes it necessary to individually produce a large number of standard sizes of sheet pile sheets or piles on any curved section of the sheet pile wall and even on straight lines to compensate for the inevitable technological deviations from the sheet pile line.

The aim of the invention is to create a tongue-and-groove design, which, being attached to a tongue-and-groove pile or panel, provides a tight and strong connection when creating a tongue-and-groove wall, both rectilinear and any other configuration in plan, which is necessary when creating hydraulic structures limited by a closed circuit sheet pile wall; creating a wall copying the relief of the coastline, as well as in other situations requiring the creation of curved sheet pile walls. In this case, the design of each individual sheet pile or panel remains constant for all described cases.

The goal is achieved by the fact that the angular unequal profile is welded to the longitudinal surface of the sheet pile or panel with the edge of the largest shelf at an acute angle with an inclination towards the edge of the free shelf, while maintaining the size between the inner surface at the apex of the angle of the angular unequal profile and the surface of the sheet pile or panel, equal to the width of a small shelf of an angular unequal profile with the addition of a minimum clearance for the mutual passage of angular unequal profiles in a tongue and groove lock, comb the angular unequal profile on the outside of the small shelf from the top of the corner is equipped with a stop, which can be continuous for the entire length of the angular non-shelf profile, as well as intermittent with a certain step, and the contacting surface of the stop with the surface of the adjacent sheet pile or panel is made (in section) in a form inscribed in a contour formed by circles drawn by radii from two centers of rotation of an angular unequal profile in relation to the second angular unequal profile in sheet pile seals, wherein the magnitude of the radii are the distances from the centers of rotation unequal angular profile adjacent to the surface of the sheet pile or the panel minus the minimum clearance for mutual transmission unequal angular profiles bung seals at different angles of rotation of adjacent sheet piles or panels.

A tongue-and-groove lock consists of two identical elements in the form of angular unequal profiles 1, 2, mounted on adjacent sheet piles or panels 3, 4 parallel to the longitudinal axis of the sheet pile or panel, while the angular unequal profile is welded to the longitudinal surface of the sheet pile or panel at an acute angle α with an inclination towards the edge of the free shelf, while the angular unequal profile 1 is welded to the longitudinal surface of the sheet pile or panel 3 with the edge of the largest shelf of width a at an acute angle α with an inclination toward the edge of the free shelf with a width of b, while maintaining the size h between the inner surface d at the apex of the corner of the unequal profile 1 and the surface of the sheet pile or panel f ₁ , equal to the small width of the shelf b of the angular unequal profile with the addition of a minimum clearance Δ, i.e. . h = b + Δ, to ensure mutual passage in the longitudinal direction of the angular unequal profiles in the tongue and groove lock.

The angular unequal profile 1 on the outside of the small shelf from the top of the corner is equipped with a stop 5, and the angular unequal profile 2 on the outside of the small shelf from the top of the corner is equipped with a stop 6. The stops 5 and 6 can be solid or intermittent with a certain step for the entire length of the angular unequal profiles 1, 2. Designs of angular unequal profiles 1 and 2 assembled with stops 5 and 6, respectively, are identical.

The contact surface k _{1 of the} stop 5 with the surface of the adjacent sheet pile or panel f ₂ and, respectively, the contact surface k _{2 of the} stop 6 with the surface of the sheet pile or panel f _{1 is} made (in section) in the form of a shape inscribed in a contour formed by circles drawn by radii r ₁ and r ₂ from two centers of rotation C ₁ and C ₂ of an angular unequal profile 1 with respect to the second angular unequal profile 2 in a tongue-and-groove lock, while the radii are equal to the distances n ₁ and n ₂ from the centers C ₁ and C _{2 of} rotation of the angular unequal full profile to the surfaces f ₁ and f _{2 of} adjacent sheet piles or panels minus the minimum clearance Δ to ensure mutual passage of angular unequal profiles in the sheet piling at different turning angles of adjacent sheet piles or panels, i.e. r ₁ = n ₁ -Δ; r ₂ = n ₂ -Δ.

The combination of adjacent adjacent sheet piles or panels with a lock when they are driven into the ground into a wall, the center line of which is a straight line, ensures their tight one-piece connection (Figure 1).

A distinctive feature of the design of the lock is the preservation of the density and strength of the combination of adjacent sheet piles or panels with their relative angular movement due to the presence of special configuration stops located on the outside of the small shelves from the vertices of the angles of unequal profiles.

The deviation of the axis of the sheet pile wall in plan from a straight line can be achieved by angular rotation of adjacent sheet piles or panels relative to each other. The design of the lock allows, without violating the density and strength of the lock connection, to carry out the relative angular movement of the sheet piles or panels from the middle position shown in Figure 1 to the extreme position shown in Figure 2, as a clockwise rotation of the panel 8 relative to the panel 7 around center C ₁ , at an angle -α, and, accordingly, the relative angular movement of the sheet piles or panels from the middle position shown in Figure 1 to the extreme position shown in Figure 3, as clockwise panel 8 relative to the panel 7 around the center C ₂ , at an angle α. Since the contacting surfaces of the stops k ₁ and k _{2 of the} angular unequal profiles are structurally inscribed in a contour formed by circles drawn by the radii from the two centers of rotation C ₁ and C _{2 of the} angular non-equal shelf profile relative to the second angular non-equal shelf profile in the tongue-and-groove lock and taking into account the minimum clearance Δ, it is possible to freely move them from the extreme position depicted in FIG. 2 to the second extreme position depicted in FIG. 3; the total angle of rotation is 2α.

The presented constructive solution of a tongue-and-groove lock allows combining sheet piles or panels of any configuration along the cross section and unfold them, if necessary, relative to each other before immersing in the ground at an angle from 0 to ± α. This, in turn, makes it possible to erect sheet pile structures (walls) strictly following the calculated trajectory without the use of additional special sheet piles or panels in the turning areas. It should be noted that this is possible provided that the design of sheet piles or panels allows such a reversal.

Figure 4, Figure 5 presents examples of the creation of sheet pile walls consisting of sheet pile panels and piles successively hammered into the ground, respectively, the axial line of which at nodes I and III is a straight line, and at nodes II and IV it has a kink - deviation from the initial position by an angle, the value of which can be set in the range from -α to + α. This illustrates the possibility of immersion in the soil sheet pile walls of various configurations in terms of using sheet piles or panels of a single design. In Fig.6 and Fig.8, Fig.7 and Fig.9 shows the relative position of the angular unequal profiles with stops as elements of the lock, respectively: with a rectilinear arrangement of adjacent sheet piles or panels and a kink - a deviation from a rectilinear position by a certain angle.
