Detailed Description
As shown in fig. 1-3, an impact compaction rod for treating small-scale roadbed defects is arranged on road construction equipment with an impact hammer 1, the road construction equipment is a road guardrail pile driver or a pavement breaking and dismantling machine, the impact compaction rod comprises a cushion block 2 detachably fixed at the bottom of the impact hammer 1 and a plurality of rod sections which are connected end to end and coaxially arranged, and adjacent rod sections are detachably and fixedly connected; the impact type compaction rod replaces the original equipment below the impact hammer 1 of the road construction equipment.
The reason why the punching by impact rather than by rotation is selected here is that the soil of the roadbed is subjected to hardening treatment and contains lime or crushed stones. The rotary punching may not be successfully completed. Meanwhile, the road construction side generally holds the highway guardrail pile driver and the pavement breaking machine, and can directly use the drivers. If rotary drilling is used, additional construction machinery is required.
The rod segment comprises a punched segment 4 arranged at the bottom of the cushion block 2, a jacking segment 6 arranged at the lowest part and used for jacking into the roadbed, and a plurality of extension segments 5 arranged end to end between the punched segment 4 and the jacking segment 6; a jacking tip 61 is fixed at the lower end of the jacking subsection 6; the jacking tip 61 is a solid inverted conical metal head used for breaking the soil of the roadbed, and can be made of wear-resistant and impact-resistant tool steel such as manganese steel or tungsten steel.

Here, so connect with connecting cable 3, for convenient dismantlement, because the connected mode commonly used, can not dismantle such as welding, but adopt bolted connection, because receive to dash segmentation 4 and the pole segmentation of below add together very long, there is horizontal rocking after being strikeed, after strikeing many times, the bolt that connects receiving to dash segmentation 4 and cushion block 2 is probably out of shape to lead to unable completion receiving to dash the dismantlement of segmentation 4, influence road construction equipment follow-up use.
In this embodiment, the connecting cable 3 is a steel wire rope, and it is necessary to secure the tightening of the connecting cable 3 in the use process, and when necessary, a turn buckle may be provided in the connecting cable 3 to assist the tightening thereof.
Ear plates welded with the buffer cushion block 2 are arranged on the side surface of the buffer cushion block 2 at intervals around the buffer cushion block 2, and ear plates welded with the punched section 4 are arranged on the top of the side surface of the punched section 4 at intervals around the punched section 4; the lower end of the connecting cable 3 is bound on the ear plate on the punched segment 4, the upper end of the connecting cable is hung on the ear plate on the cushion block 2 through a shackle, and the ear plates above and below the same connecting cable 3 correspond to each other and are aligned up and down. When the dismounting is needed, only the shackle needs to be dismounted.
The jacking tip 61 is sleeved with a reaming ring 62, the reaming ring 62 is a steel ring with the outer diameter larger than the outer diameter of the jacking section 6 and in clearance fit with the jacking tip 61, the jacking tip 61 and the jacking section 6 are welded at the connecting position of the jacking tip 61 and the jacking section 6, the reaming ring 62 is obliquely arranged, and the upper portion of the reaming ring is arranged in the lug plate at the connecting position of the jacking tip 61 and the jacking section 6 in a penetrating manner. The diameter of the hole expanding ring 62 is slightly larger than the outer diameter of the compaction rod, so that a hole expanding effect is achieved, and when the compaction rod is lifted upwards, the hole expanding ring 62 falls down, so that the compaction rod is lifted.
Adjacent rods are socket connected in segments and locked by a rotary snap. The rotary buckle can adopt a fin which is meshed in a rotating way in a screw type breechblock, and can also adopt a rotary buckle in a water pipe joint, and the rotary buckles are common structures and are not described in detail. The main purpose here is to ensure a quick assembly and disassembly of the rod segments, while the socket and the spigot are solid.
The rod segments are seamless steel tubes, the outer diameter of each steel tube is 10-30cm, the wall thickness of each steel tube is 3.5-7mm, and the length of each steel tube is 1.5-2.5m. The top of the flushed segment 4 is horizontally provided with a flushed top plate 41 which is connected with the flushed segment 4 in a welding mode, stiffening ribs are arranged between the flushed top plate 41 and the side face of the flushed segment 4 at intervals around the flushed segment 4, and the stiffening ribs are respectively connected with the side face of the flushed segment 4 and the lower surface of the flushed top plate 41 in a welding mode. The position is concentrated in stress, so that the stiffening ribs are arranged to improve rigidity and avoid deformation.
The percussion hammer 1 comprises a T-shaped hammer head and a hammer box sleeved outside the hammer head, a hammer rod of the hammer head penetrates through a top plate of the hammer box and is connected with the top plate in a sliding mode, and a buffer cushion block 2 is connected with a bottom flange of the hammer box. The impact hammer 1 of this structure facilitates the installation of the impact compaction bar in the present application.
And a stiffening rib is arranged between the jacking tip 61 and the side surface of the jacking section 6, is arranged around the jacking section 6 at intervals and is respectively welded with the side surface of the jacking section 6 and the side surface of the jacking tip 61. Here again, the location of concentrated force, and therefore stiffening ribs are provided to increase stiffness and avoid deformation.
As shown in fig. 4, the method for using the impact type compaction rod for treating small-scale roadbed defects comprises the following steps:
the method comprises the following steps: the cushion block 2 and the impacted segment 4 in the utility model are used for replacing the original components under the impact hammer 1;
step two: installing a jacking subsection 6 below the impacted subsection 4, starting impact punching, stopping impact each time the lower end of the impacted subsection 4 is close to the ground, connecting a new lengthened subsection 5 between the impacted subsection 4 and the jacking subsection 6, and then continuing impact until the hole depth meets the requirement;
step three: pulling out the compaction rod, removing all the jacking sections 6 and the lengthening sections 5 section by section, and then filling the punched holes with 8% cement soil or plain soil;
step four: and repeating the first step to the third step to finish the repair of the roadbed defects, then detaching the buffer cushion block 2 and the impacted subsection 4, and replacing the original components under the impact hammer 1.
The above-mentioned embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
