Definitions

  • the present invention relates to construction using three-dimensional geocell (hereinafter referred to as “geocell”) including construction of motor roads, railways, runways for airfields, while building facilities for various purposes, landscape development, and reinforcement of ravines and slopes.
  • geocell three-dimensional geocell
  • the laying of three-dimensional geocell comes to the following main steps:
  • a geocell section having a length as defined by design is accommodated on a special device of the laying machine or a platform connected thereto and can be of drum-type.
  • Geotextile rolls are also accommodated on the laying machine or a platform connected thereto.
  • a Geocell is stretched by means of actuating tools (plates, boxes, disks, sprockets) of a corresponding mechanism of the laying machine or by hand. Filling the cells of a stretched geocell with bulk material fed from a bunker situated on the laying machine or a platform connected thereto is conducted practically immediately after their formation as a result of a stretching operation that allows using provisional anchorage pillars keeping the geocell in a stretched state only at the initial part of geomaterial installation, until their filling, with their subsequent removal. Further stretching does not require using anchorage pillars because geotextile and geocell will be held by a layer of filled material.
  • the laying machine is equipped with a mechanism for lifting the sleeper frames and a device for feeding geomaterials into the area under sleepers, a device for stretching geomaterials, filling, leveling and compacting bulk material, the said devices being in operating state in the area under sleepers.

  • a laying machine platform is installed on a road segment (site) under repair where all technological operations on site preparation preceding the laying of geomaterials have been completed.
  • the Geocell is pulled-out from the spool (drum) to the required length. This pulling-out is implemented manually or by means of manually- or electrically operated winches or any other similar mechanisms.
  • the geocell is turned in a transverse plane by the required angle to place the geocell on the edge for stretching.
  • a stretching device is arranged over the geocell, its boxes are inserted by their edges into pockets of a geocell section and forced apart by an angle appropriate for stretching the geocell to a predetermined width.
  • the disadvantages of the closest analogue are the insufficient mechanization of the geocell's winding and unwinding from the spool and also the geocell expanding process, the complexity of controlling the uniformity of winding, unwinding and expanding, and hence the insufficient effectiveness of works on geocell laying.
  • the main objective of the proposed technical solution is the elimination of the cited disadvantages owing to the mechanization of winding, unwinding and expanding the geocell and also improvement of the laying machine.
  • a geocell laying machine comprising equipment for storing and expanding the geocell, the said equipment including a spool rotating on a frame and designed to wind, store and unwind a length of geocell consisting of separate geocell modules of predetermined sizes connected in series, the said spool being connected with an actuator providing control of uniform winding and/or unwinding the length of the geocell along the spool axis, means for advancing the length of the geocell along an axis from the spool, at least two cross members that enable the expanding of the geocell and can be forced apart to form a predetermined angle between them, the said cross members being connected with engaging means to hold the geocell edges in the process of its expanding between the said cross members.
  • the actuator further allows turning the length of the geocell to the flat position to provide for its winding to the spool and also turning the length of the geocell to the sideways position during its unwinding from the spool to provide for advancing the length of the geocell along the guideway to the cross members.
  • the means for advancing the length of geocell comprise guiding and/or pulling-out rollers and a power drive whose rate of rotation is consistent with the speed of the laying machine to provide for a uniform advancing of the length of the geocell.
  • the means for advancing the length of the geocell can also comprise restraints to prevent the ejection of the length of the geocell from the guideway in the course of operation of the laying machine.

  • movements of the spool and actuator are synchronized by means of an automatic control system.
  • this concerns the synchronization of motor speeds in accordance with placement parameters.
  • Also equipment for expanding the geocell during its laying by means of a laying machine comprising means for advancing a length of geocell consisting of separate geocell modules of predetermined sizes connected in series along a guideway, at least two cross members that provide for expanding the geocell and can be forced apart to form a predetermined angle between them, the cross members being connected with engaging means to hold the geocell's edges in the process of its expanding between the cross members.
  • the said equipment comprises guiding and/or pulling-out rollers and a power drive whose rate of rotation is consistent with the speed of the laying machine to provide for the uniform advancing of the length of the geocell and also restraints to prevent the ejection of the length of the geocell from the guideway.

  • seams for example, lateral linear weld seams arranged chequerwise
  • Examples of geocell are known from Russian patents No. No. 40751, 98763 for utility models.
  • the said geocell sections have generally parallelepiped form with the following sizes: length of about 6m, height of up to 0.2 m, and width (thickness) of about 0.12 m. These sizes can be changed but because the modules are of sufficient weight (about 10 kg per meter of a module), an increase in their length has essential limitations concerning storage, transportation and laying.
  • Generally geocell modules are stored in stacks and are expanded in use and attached to each other by metal staples using a mechanical (electromechanical) stapler according to a technological process.
  • a geocell For storing, transporting and carrying out works on use of a geocell it is proposed in the present invention to use not the above-mentioned separate modules but their sets combined into one length of a geocell having a predetermined size, which can be wound to a spool to feed the geocell to a mechanism for its stretching (expanding).
  • Forming the length of the geocell is in cell-by-cell fastening of modules of a predetermined length to each other (for example, using a mechanical ore electromechanical stapler) in a lateral direction to a length defined by a technological process.
  • all the geocell bands which form a module after being fastened can have the same width excluding the second and last but one which are of a lesser width whereby one or two longitudinal pockets (above and below of the module) are formed along the module (the length of the geocell) following the first and before the last bands. These pockets are used for engagement while stretching the geocell and they are described in the analogue in detail. Other options of fixing the geocell edges by further engaging elements or applied pressure are also possible.
  • the manufactured length of the geocell is accommodated on a device for storing and transporting (spool, rack, package, box, coil and so on), transported to a site and installed on a carrier. Then the length of the geocell is stretched to the necessary size along a carryover conveyor from the device for storing and ridges of the device for expanding the geocell are inserted into the above-mentioned pockets.
  • One embodiment of a device for expanding the geocell comprises two horizontal cross members, for example, having a box-like construction and provided with ridges to be inserted into longitudinal pockets of the geocell.
  • Cross members are on the same plane and can be rotated on vertical axes providing thereby the possibility to force them apart by an angle with relation to each other.
  • Cross members can be forced apart manually or using mechanical, electrical or hydraulic drives.
  • Rollers designed to guide the length of the geocell by its pockets to the ridges and/or for enhancing pulling-out the length of the geocell from the device for storage can be used in combination with cross members.
  • the said rollers can be biased to the length of the geocell passing through it, have a surface of increased frictional properties and are provided with a power drive whose rotation is synchronized with the carrier movement speed.

  • the cross members are fitted with ridges adapted for insertion into pockets of a length of the geocell.
  • the length of the geocell is inserted into pockets while it passes guiding rollers 5 and 7 .
  • Roller 5 has power drive 6 (for example, electrical or hydraulic drive gear).
  • Roller 7 can be fitted with biasing device 8 .
  • Rollers 5 and 7 have surfaces with increased frictional properties and are supplied with a power drive and biasing device in accordance with the operating conditions of a carrier.
  • Movement of the length of the geocell for the expanding step is implemented along a guideway, a chute of conveyor 9 , restraints 10 being provided at danger points to prevent ejection of the length of the geocell to the side.
  • Pointed studs anchor pillars are used to fix the length of the geocell on the ground.
  • the laying machine is installed at the beginning of its working motion.
  • Cross members 1 and 2 are unlocked from their transport position and, if this is envisaged by a manual, placed on studs of axes of rotation 3 and 4 and fixed on them.

  • the length of the geocell is stretched along conveyor 9 between guiding rollers 5 and 7 and placed by its pockets on the cross member ridges or otherwise fixed on the guideway.
  • the first few rows of cells of the stretched geocell are fixed on the ground by provisional anchoring pillars which should be removed after the three-dimensional geocell is filled with free-flowing substance in accordance with operational procedures.
  • the laying machine begins its working motion and concurrently the geocell being fixed on the ground is drawn from a storage device (spool) stretched (expanded) between the cross members forced apart and remains in a stretched position if its cells are being filled at the same time with a free-flowing substance or it is being fixed along the edges by provisional anchoring pillars.
  • the device can be fitted with guiding friction rollers having a power drive whoseh rate of rotation is consistent with the speed of the laying machine, the said guiding friction rollers enhancing pulling-out the length of the geocell.
