Geocell laying machine with equipment for geocell storage and expansion during the laying thereof

Abstract

The invention relates to construction using geogrids. The application proposes a refined geogrid laying machine, comprising equipment for storing and expanding the geogrid, including a spool rotating on a frame and designed to wind, store and unwind a length of geogrid consisting of separate geogrid modules of predetermined sizes connected in series, the said spool being connected with an actuator enabling control of uniform winding and/or unwinding the length of the geogrid along the spool axis, means for advancing the length of geogrid along a guideway from the spool, at least two cross members that provide for expanding the geogrid and can be forced apart to form a predetermined angle between them, the said cross members being connected with engaging means to hold the geogrid edges in the process of its expanding between the said cross members.

1 . A geocell laying machine, characterizing in that it comprises an 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 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 a guideway from the spool, at least two cross members that provide an expanding 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. 
     
     
         2 . The laying machine according to  claim 1 , characterizing in that the actuator further provides turning the length of the geocell to the flat position to enable winding to the spool. 
     
     
         3 . The laying machine according to  claim 1 , characterizing in that the actuator further provides turning the length of the geocell to the edge position during its unwinding from the spool to enable advancing the length of the geocell along the guideway to the cross members. 
     
     
         4 . The laying machine according to  claim 1 , characterizing in that the said means for advancing the length of the 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 enable a uniform advancing of the length of the geocell. 
     
     
         5 . The laying machine according to  claim 1 , characterizing in that the said means for advancing the length of the geocell comprise restraints to prevent its ejection from the guideway. 
     
     
         6 . Equipment for storing the geocell, characterizing in that the said equipment comprises 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 geocell along the spool axis. 
     
     
         7 . The equipment according to  claim 6 , characterizing in that movements of the spool and actuator are synchronized by an automatic control system. 
     
     
         8 . The equipment according to  claim 6 , characterizing in that the actuator further provides turning the length of the geocell to the flat position during its winding to the spool. 
     
     
         9 . The equipment according to  claim 6 , characterizing in that the actuator further provides turning the length of the geocell to the edge position during its unwinding from the spool. 
     
     
         10 . Equipment for expanding the geocell during its laying by means of a laying machine, characterizing in that the said equipment comprises a means for advancing a length of the 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 edges in the process of its expanding between the cross members. 
     
     
         11 . The equipment according to  claim 10 , characterizing in that it 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 enable a uniform advancing of the length of the geocell. 
     
     
         12 . The equipment according to  claim 10 , characterizing in that it comprises restraints to prevent the ejection of the length of the geocell from the guideway.
