Description

The utility model relates to equipment for repair work on trunk oil pipelines and oil product pipelines (MN and MNPP) in conditions of water cut and soft soils (type II and III marshes), and in particular to sheet pile positioning devices for erecting a sheet pile.

Known sheet pile collapsible fence for arrangement of the pit [patent for invention RU 2530142 C2, publ. 10/10/2014, IPC: E02D 17/04] containing four racks, a guide frame and sheet piles. Racks are installed at the corners of the repair pit. The guide frame consists of four I-beams with holes in the wall through which I-beams are worn on racks. The racks are made holes in which holding fingers are inserted to fix the I-beams at a given height. The sheet piles are pressed into the ground and are located along the I-beams around the guide frame with the formation of a closed sheet piling.

Also known conductor for immersion piles in a cordless manner [patent for utility model RU 126335 U1, publ. 03/27/2013, IPC: E02D 7/12], which includes a rectangular flat frame with paired logs along its long sides and transverse ties, as well as removable steel clamps for holding piles mounted on paired logs. Each clamp is made of two rectangular vertical frames with upper and lower arches, fixed by ruffs and pressed by horizontal bolts to paired logs. On the arcs there are sheet stops and clamps for piles with spring-loaded square rods, at the ends of which cross-section piles curved under the section are fixed, as well as fixed cylindrical cups screwed with movable, providing an adjustable stop for spring-loaded rods.

The closest analogue of the claimed utility model is a device for creating a tongue-and-groove wall of a foundation pit [patent for invention RU 2122071 C1, publ. 11/20/1998, IPC: E02D 11/00, E02D 7/00, E02D 9/00], containing the mechanism for dipping and removing tongues, the mechanism for raising and lowering the walls, guide racks, hydraulic cylinders and a conductor. The immersion and extraction mechanism is made in the form of several hydraulic cylinders. Cases of hydraulic cylinders are equipped with a common frame installed in guide racks with the ability to move along them. The length of the frame is equal to the length of the sheet pile wall. On the contour of the pit, marking is made. The conductor is laid out according to the marking and guide racks are installed on it. The dowels are connected to the headrests. A frame with a hydraulic cylinder and tongues, lifted by the earring by means of a crane, is installed in the guide racks.

The disadvantage of the closest analogue is that the conductor design is single-level, which is not enough to effectively guide and hold the tongues in a given position.

The task to which the claimed utility model is directed is to ensure safety and reduce the time spent on work when arranging a foundation pit in conditions of water cut (II and III type of bogging).

The technical result achieved by using the claimed utility model is the elimination of vertical deviations of the sheet pile when it is buried in the ground without the use of a vibrator.

This problem is solved, and the technical result is achieved by the fact that the positioning device of the sheet piles during the construction of a sheet pile collapsible fence includes four sheet pile racks on which the guide frame is mounted, four additional posts installed on top of one of the ends of each sheet pile fence, the conductor mounted on additional racks above the level of the guide frame and made in the form of a beam with holes through which it is installed on racks, and the guide channel, paired with the beam by means of the mounting unit with a guaranteed gap between them, while on the side surface of the channel channel along its length there are through holes for installing limiters, and blind holes for fixing are made on the side surface of the beam along its length limiters, and through holes in the guide channel and blind holes in the beam are located opposite and spaced along the length of the guide channel and alky, respectively, at a distance of not less than the length of the sheet pile in its cross section installed between the beam and the guide channel in the gap formed by the two closest stoppers, and the attachment point of the beam and the channel channel includes a sleeve placed between them, the length of which is not less than the width of the sheet pile in it cross section.

In addition, holes are made in the racks and additional racks in which support fingers are mounted for fixing at a predetermined height of the guide frame and the conductor, respectively.

Additional racks are installed on top of one of the ends of each of the racks of the sheet piling with the help of a glass-type connection and are fixed in it by means of a clamping clamp or a through clamp.

In addition, the limiters installed in the holes of the beam and the guide channel are made in the form of quickly removable fingers with hinged latches.

Additionally, the conductor may be able to install sheet piles, which are a split sector of a cylindrical pipe.

In addition, the conductor may be able to install sheet piles, which are pairs of split sectors of a cylindrical pipe, interconnected along one of the longitudinal ends by a welded joint with the formation in cross section of an m-shaped profile.

The inventive device is intended for positioning and guiding the sheet piles during the construction of a sheet piling collapsible fence. The device is used only when deepening sheet piles with an excavator, but not when using a vibrator.

The device includes four posts 1 of the sheet piling, on which the guide frame 2 is installed. Four additional posts 3 are installed on top of the free end of each sheet 1 of the sheet piling, which is not buried in the ground, by means of a glass-type connection 4 and are fixed in it by means of a clamping lock 5, for example, of type "Lamb", or through the latch 6, for example, type "hairpin". In the racks 1 and additional racks 3, holes 7 are arranged in rows for mounting the support fingers, which allows the guide frame 2 to be fixed at a given height.

The conductor 8 mounted on additional racks 3 through the support pins inserted into the holes 7 is higher than the level of the guide frame 2, made in the form of a beam 9 with holes 10 for installation on additional racks 3, and a guide channel 11, coupled to the beam 9 through the mount 12. The mounting unit 12 of the beam 9 and the guide channel 11 is made in the form of a stud 13 with a clamping nut 14. The guaranteed clearance between the beam 9 and the guide channel 11 is ensured by the sleeve 15 located on the stud 13 between them , the length of which is not less than the width of the sheet pile 16 in its cross section.

On the lateral surface 17 of the guide channel along its length, through holes 18 for installing the stops 19 are made. On the lateral surface 20 of the beam along its length there are blind holes 21 for fixing the stops 19. Through holes 18 in the guide channel 11 and blind holes 21 in the beam are opposite each other. The through holes 18 are spaced apart from each other along the length of the guide channel 11, and the blind holes 21 are spaced from each other along the length of the beam 9 to a distance not less than the length of the sheet pile 16 in its cross section. The limiters 19, installed in the holes of the beam 9 and the guide channel 11, are made in the form of quickly removable fingers with hinged latches.

The tongue-and-groove piles 16 installed in the conductor 8 between the beam 9 and the guide channel 11 are located in the gap formed by the two closest stoppers 19. The tongue-and-groove piles 16 can be made in the form of a split sector of a cylindrical pipe. In addition, the sheet piles 16 can be made in the form of a pair of split sectors of a cylindrical pipe, interconnected along one of the longitudinal ends by a welded joint with the formation in cross section of an m-shaped profile. The end of each sector of the cylindrical pipe to be buried in the ground is pointed.

The claimed device operates as follows.

To form a sheet pile fence, the racks 1 are driven in, the guide frame 2 is assembled and fixed on the posts 1 at the site of the sheet pile fence construction. Four racks 1 sheet pile fencing set in the corners of the torn out repair pit. Support fingers are inserted into the holes 7 of the racks, then a guide frame 2 is mounted on the racks 1, resting on the support fingers holding it on the racks 1.

Additional racks 3 are installed on racks 1 of the sheet piling through the junction type of the glass type 4 and fixed with clamps (through 6 or clamping 5). Then, the support fingers are installed in the holes 7 of the additional racks at the required height. The conductor beam 9 through the holes 10 made in it is put on additional racks 3 and fixed on the supporting fingers.

Groove piles 16 are installed along the perimeter of the guide frame 2 from its outer side. Sheet piles 16 are installed in the conductor 8 between the beam 9 and the guide channel 11 so that the edge of the sheet pile 16 touches the guide frame 2. Between the beam 9 and the guide channel 11 of the conductor through them holes 18 and blind holes 21 respectively give rise to the stops 19 in the form of quickly removable fingers and fix them with hinged latches. Limiters 19 serve to limit the position of the sheet pile 16 relative to the beam 9 and ensure its orientation in a given installation direction. After the sheet piles 16 are deepened by the excavator bucket to the level of the conductor beam 9, the limiters 19 are removed and installed further along the length of the beam 9 to a distance of not less than the length of the sheet pile 16 in cross section for immersion of the next sheet pile 16. The required number of sheet piles 16 is installed according to the circuit described above.

After installation and partial deepening of the sheet piles 16 along the required length of the repair section, the conductor 8 is dismantled and installed on the next section of the repair pit.

After installation and partial deepening of the sheet piling into the ground around the entire perimeter of the repair pit, the conductor 8 and additional racks 3 are dismantled. Then immerse sheet piles 16 to the level of the guide frame 2.

The result is the exclusion of vertical deviations of the sheet pile when it is buried in the ground without the use of a vibro driver.
