Abstract

The present invention relates to a method for compacting the internal sides of dykes or dams with a polygonal impacting roller. The polygonal road impacting roller rolls on the internal ground of the dykes and dams; the shape of the road impacting roller can be triangular, tetragonal, pentangular or hexagonal; impact force is generated by making use of the rotation of the roller according to the difference value of an external diameter R and an internal diameter r of each angle; the depth H affected by compaction can reach to 5 meters, and the depth H is greatly larger than the compacted depth of the traditional circular road compacting roller. The method of the present invention has the advantages of large compaction depth and high speed. The present invention is suitable for the compaction of the ground surface on the internal sides of the dykes and dams; the present invention prevents flood outside of the dykes from infiltrating into the dykes from the lower side of the ground, and the safety of the dykes and dams is ensured.

Description

With the debulking methods of polygonal impacting compacting roller to internal side of dyke or dam

The present invention relates to a kind of soil debulking methods, particularly a kind of with the debulking methods of polygonal impacting compacting roller to internal side of dyke or dam.

For Jiang Di, river levee, Hu Di, reservoir dike, extra large dykes and dams, when outside the dike during flooding, the dyke that often needs reinforcement, dykes and dams this when building by laying bricks or stones, successively tamp through the soil, but in the soil of internal side of dyke or dam often without compacting, when flooding, owing to have underground defectives such as space, crack, cave or tree root under the face of land near the internal side of dyke or dam, and form the inside and outside pipeline that is communicated with of dike, generation forms piping to dike inboard soil infiltration, influences the safety of dykes and dams.When carrying out soil, compacting dike inboard with common road roller, because traditional circle presses the road to roll when roll extrusion, the degree of depth of compacting is less, generally about 0.3 meter, only be suitable for successively laying the ground of compacting successively, to the internal side of dyke or dam ground that has formed, then can not the one or many roll extrusion that the ground compacting is very dark without compacting, so can not be with the slit compacting shutoff of underground inside and outside the dike than the depths, the difficult problem that can not separate the percolating water in the inboard soil that breaches a dyke.

The object of the invention provides a kind of with the debulking methods of polygonal impacting compacting roller to internal side of dyke or dam; adopt this method can be with the soil compacting of dike inboard; its compacting depth can reach 5 meters; underground hidden danger such as the space, crack, tree root, cave of the following deep soil in the face of land have been eliminated in assurance; thereby reduce outside dykes and dams because the possibility that the pressure of water seeps water in dike has further been protected the stability and the safety of dykes and dams.Compare all raisings greatly on compacting depth and speed with traditional vibrations compacting.

The present invention seeks to realize by following technical scheme.With the debulking methods of polygonal impacting compacting roller to internal side of dyke or dam, be on the soil of internal side of dyke or dam, carry out roll extrusion with polygonal pressure road roller.The gabarit of this polygonal pressure road roller can be 3 dihedrals, 4 dihedrals, 5 dihedrals or 6 dihedrals.Adopt this debulking methods to utilize the polygon projection of this roller (being external diameter R) and recessed portion (footpath r promptly) that the range difference of the roll center of this roller is finished ground generation enormous impact power, this polygonal impacting compacting shakes the high-energy that the compacting difference is shock compaction than traditional circular roller compacting or circular roller, and the energy of shock compaction and speed all substantially exceed the vibrations compacting.With the inboard ground of the method compacting dike, can eliminate underground space prevent dike outward water from underground leakage to dike, the guarantee embankment safety.

As mentioned above, because the present invention adopts the polygonal roller, the high-energy that the external diameter that utilizes its polygonal position and the difference of internal diameter produce impacts in the compacting dike the bigger soil of the degree of depth under the face of land, can eliminate underground space, avoids the piping generation, guarantees the safety of dykes and dams.This method is particularly suitable for the soil compacting of internal side of dyke or dam, prevents seepage usefulness.

Do concrete introduction with embodiment below.

Fig. 1 is with the inventive method compacting work schematic diagram on the soil in dike,

The impact force schematic diagram of Fig. 2 for being produced with the shock compaction of polygonal roller.

As shown in Figure 1, be dykes and dams 1 on the right side of flood 5, the lower right of its back slope 2 is the inboard soil 3 of dike.Polygonal impacting compacting roller 4 drags down at the motor vehicles (not shown), rolls on the inboard soil 3 of dike.Diagram polygonal roller 4 is leg-of-mutton, 120 ° of every angular spacings, then roller revolution hexagonal angle impacts once, also can be 4 jiaos, 5 jiaos or 6 dihedrals, when pressing the road roller to rotate, produce impact force according to the external diameter R at every angle, the difference of footpath, lining r, according to the material difference, the shock effect depth H can reach more than 5 meters, is far longer than the degree of depth of pressing road roller compacting with circular, illustrates fan-shaped part 6 and is the shock effect zone.When this roller rolling impact compacting being shown as Fig. 2, the measured result of the impact force that ground is produced, top is depicted as this roller residing angle position when rolling, when the bottom is divided into this angle position of correspondence, the surge that this roller produces ground, roller rotation rate is per minute 90-120 time, as can be seen, when turning to pressure that 0 ° 60 ° and other position produce when being 1g, when then turning to 120 ° of positions, about 12 times when the surge of its generation is about other position, impact three times in the roller revolution.Show by test, be about more than 10 times of compacting of vibrations with its impact energy of polygonal impacting debulking methods, speed is more than 3 times of compacting of vibrations, and compacting depth can reach more than 5 meters, per hour can finish the soil more than 20,000 square metres.

Claims

1, with the debulking methods of polygonal impacting compacting roller, it is characterized in that on the soil of dike inboard, carrying out roll extrusion with polygonal pressure road roller to internal side of dyke or dam.

2, method according to claim 1 is characterized in that the gabarit of described polygonal pressure road roller is 3 dihedrals, 4 dihedrals, and 5 dihedrals or 6 dihedrals, the limit of described roller is partly formed with recessed by protruding partly.
