The invention relates to an anchored retaining walls and can be used mainly in hydraulic engineering during the construction of berthing facilities and the conduct of shore protection works, as well as in industrial and civil construction.

Famous tongue-and-groove wall with anchor device, comprising scored in a number of piles, connected by locks, anchor pull, metal distribution belt and anchor plate. In the specified well-known wall mount anchor thrust is mounted in each pile and made in the form of rigidly connected to it a tubular metal frame and mortgage team supports attached to the frame and the pile. Pile placed inside the mount concreted wholly or partially (RU # 2275456).

Known retaining wall with anchor device, including personal piles, anchor piles, anchor rods, fasteners anchor rod to the face of the piles and the nodes fastening anchor rods to anchor piles. The attachment anchor thrust to the face of the pile consists of a plug rigidly fixed to the front face of the pile and connected to the fork with the axis of the lugs, which, in turn, are rigidly connected to one end of the anchor rod. The other end of the anchor thrust threaded and provided with a tension nut, which constitute the attachment anchor thee and to anchor the pile (brochure ThyssenKrupp GfT Bautechnik - the prototype).

The disadvantage of retaining walls is that in the construction of hydraulic engineering structures installation of anchor rods under water have to do with divers and related technology that significantly increases the cost of construction.

The technical task of the present invention is to improve convenience and reduce the complexity of installation of the retaining wall.

The technical result - the possibility of installation and fastening of the anchor rod retaining wall with boats with the exception of underwater engineering works.

The problem is solved due to the fact that the retaining wall, mainly for hydraulic construction, including facial piles, anchor piles, at least one anchor rod and the mountings of the ends of the anchor thrust respectively to the front and anchor piles, according to the invention, each node of the fastening anchor thrust to the corresponding front or anchor pile made in the form of sportowego compounds consisting of two locking elements, one of these locking elements fixedly mounted on the pile so that its upper end is located above the water level in the water area, and the second locking element of the fastening Assembly is connected using a hinge with one end of the anchor rod and installed with the possibility vertically is th translational movement relative to the first locking element, mounted on the pile, the length mentioned locking elements of the mount at least one end of the anchor pull made of the conditions for the possibility of moving the movable locking element together with the United with him by the end of the anchor thrust below the water level in the water area to a predetermined depth and fixing it at a point above the water level in the water.

The length of the locking elements of the attachment of the second end of the anchor rod in this case may be 20-30% of the length of the locking elements of the attachment of the first end of the anchor rod.

In the proposed retaining wall locking elements can be made of locking parts rolling tongue. The anchor rod can be made of strips, pipes or beams of circular or rectangular cross section.

In the proposed retaining wall anchor rod can be made of a composite of at least two parts connected to each other via a sheet locking elements, each of which is fixed to a corresponding adjacent part of the anchor rod.

Execution of attachment anchor thrust respectively to the front and anchor piles in the form of sportowego connection (sportowego castle) greatly simplifies the installation of anchor rods, because the technology institution of sheet piling in the castle quite worked out.

The proposed design is Ktsia of the mount allows you to connect to the castle the castle the elements of this compound over the surface of the water, because one of these elements is fixed on the pile and its upper end is above the water level in the water. As sportowy lock allows relative longitudinal movement in the United lock elements, then after connecting to the castle the second movable locking element together with the United with him by the end of the thrust anchor moves along the axis of the pile relative to the element fixed to the pile. Since the length of the locking elements of the mount at least one of the ends, or perhaps even both ends of the anchor rods are made of the conditions for the possibility of moving the movable locking element below the water level to the design elevation, connected with it the end of the anchor thrust also lowered its design depth. In this position, the movable locking element can be fixed relative to the stationary locking element in the upper part, protruding above the water level within the, with the release of any known construction, for example using a pin (not shown).

In the case when only one end of the anchor thrust on the project should be lowered to a predetermined depth, and the second end must be attached to the corresponding pile in its upper part, jutting out over the water, the length of the locking elements of the attachment of the second end of the anchor thrust is less than the Lin locking elements of the attachment of the first end of the anchor rod and may be 20-30% of their length.

The present invention allows to carry out all work in connection anchor rods with piles with boats without the use of underwater engineering works, and since joining the ends of the anchor pull, and fixing them in the United situation are at the top.

In addition, sportowy lock also allows some relative rotation of its elements around a vertical axis that in addition to turning the locking elements around their horizontal axes (joints) compensation increases opportunities when you install anchor rods, reduces internal stresses.

When performing the locking elements of the locking parts of hot-rolled sheet piling made in the factory, not only reduces the intensity of the attachment anchor to pull the pile, but also improve conditions for Assembly, since such locking elements do not have sharp edges and burrs in the area sportowego castle that provides smooth, without a lot of effort moving the movable locking element along fixedly mounted on the pile, which facilitates installation. In addition, the locking elements are made of finished rolled sheet piling, have a protective anti-corrosion coating, which increases their lifespan.

Running anchor traction compound at least two parts connected is between a using elements of interlock, makes it more flexible, it is more convenient to be transported in disassembled form, it is easier to install.

Further, the invention is illustrated on the example of a specific implementation with reference to the accompanying drawings, which depict:

One edge (upper end) of each element 6 is placed near the end of the pile 1 or combine with him. Length sportowego element 6, i.e. its length along the pile, runs from the condition that after immersion of the front pile 1 at the design depth of the top edge of the element 6 is positioned above the water level in the water area, and its bottom edge was located at a depth slightly above the design point of the place of attaching the anchor thrust 3. The length of the rolling element 7 is approximately equal to the length of the element 6.

To anchor piles are welded locking elements 10.

Separately collect anchor thrust 3, to the ends 9 which by means of joints (axes) 8 attach the movable locking elements 7 to node 4, and the second end 13 of the anchor pull 3 attach the movable locking element 11 by hinge 12 to node 5. The length of the elements 10 and 11 of the mount 5 may be the same as the length of the locking elements 6 and 7, and can be 20%-30% of their length depending on the schema of the anchor.
