Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
Referring to fig. 1, the present embodiment includes a weight bar 3, an impact post 4, a guide 5, and a guide tube 6.
The upper end of the weighting rod 3 is provided with a traction hole 2, and the center of the lower end is provided with female threads.
The upper end of the impact column 4 is provided with a male thread, and the lower end is provided with an expansion head 7.
The inside cavity that is provided with of stand pipe 6, the upper end is provided with the round hole, and the round hole diameter is less than enlarged head 7 diameter and cavity diameter, so enlarged head 7 just can not fall out from the round hole, and the round hole can be passed to the upper end of impact post 4. The lower end of the guide pipe 6 is sealed, a mounting hole 8 is formed in the guide pipe, and female threads are arranged in the mounting hole 8.
The impact column 4 is slidably mounted up and down in a cavity inside the guide tube 6, and the enlarged head 7 is located above the lower end of the guide tube 6. After the upper end of the impact column 4 passes through the round hole at the upper end of the guide pipe 6, the male thread at the upper end of the impact column 4 is connected with the female thread at the lower end of the weighting rod 3, so that the impact column 4 and the weighting rod 3 are fixedly connected together.
The guide device 5 is cylindrical, a cylindrical hole is formed in the middle of the guide device, the guide tube 6 is fixedly arranged in the cylindrical hole in a penetrating mode, and the guide device 5 is fixedly sleeved outside the guide tube 6. The guide device 5 plays a role in guiding in the sampling process, and prevents the utility model discloses rock too big.
The field sampling operation flow is as follows:
connecting a steel wire rope 1 on a construction machinery winch on a traction hole 2 at the upper end of a weighting rod 3, connecting male threads at the upper end of an impact column 4 with female threads at the lower end of the weighting rod 3, installing a guide device 5 outside a guide pipe 6, connecting male threads at the upper end of a thick-wall soil sampler 9 of the existing equipment with female threads at the lower end of the guide pipe 6, starting the winch, hoisting the weighting rod 3, the impact column 5, the guide pipe 6 and the thick-wall soil sampler 9, installing a guide device 5 with a proper diameter which is slightly smaller than the diameter of a pile hole 11 of a lime soil compaction pile, slowly placing the device on the surface of a lime soil filler 10 which is just tamped in the pile hole 11, pulling up the impact column 5 (the stroke is smaller than the height of a cavity of the guide pipe 6), loosening the winch to enable the weighting rod 3 and the impact column 5 to freely fall (the maximum height of a free fall is 1.2 m), and beating the lower end of the guide pipe 6 by an expansion head 7, repeatedly pulling up and putting down, pulling out the device by a winch and horizontally placing on the ground after the thick-wall soil sampler 9 is driven into the soil filler 10 and reaches the sampling depth, unloading the thick-wall soil sampler, taking out the soil sample, and completing the sampling.
The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
