Detailed Description

The invention is described in detail below with reference to the figures and the embodiments.

As shown in figures 1, 2, 3, 4 and 5, the simple sediment detection device for the large-diameter cast-in-place pile comprises two correspondingly arranged bottom plates 1 and a support consisting of longitudinal plates 2 vertically arranged on the bottom plates, circular cavities are correspondingly arranged on the two longitudinal plates, bearings 15 are arranged in the circular cavities, a connecting shaft 3 used for connecting the two bearing inner rings is welded between the two bearing inner rings, a turntable 4 used for rotating the connecting shaft is arranged at one end of the connecting shaft, a steel wire rope 5 is arranged on the connecting shaft, a circular ring 6 is arranged at one end of the steel wire rope, three welded deformed steel bars 7 with the diameter of 25mm are welded below the circular ring, a first bolt hole 8 is arranged on each deformed steel bar, the simple sediment detection device further comprises a square cavity 9 with an open top and a flat-bottom steel plate 10 which is welded at the bottom of the square cavity and is used for contacting with the top surface of sediment, the thickness of the flat-bottom steel plate is 4mm, second bolt holes 11 which are correspondingly arranged on two side walls of the square cavity and, and connecting bolts 12 are arranged in the first bolt hole and the second bolt hole, and can be double-headed bolts.

Still include one when wire rope transfers preset position, with the locking subassembly of carousel locking, the locking subassembly is including locating the first through-hole on the carousel to and locate T shape 13 in the first through-hole, be equipped with a plurality of annular distributions be used for with the second through-hole 14 of T shape grafting that distribute on the bottom plate of adjacent carousel one side, first, the through-hole diameter is the same, the T shape be two perpendicular welded and with first, the iron pipe of through-hole adaptation.

The utility model discloses a use method does: welding 3 pieces of deformed steel bar with the diameter of 25, welding a circular ring at the upper end of the deformed steel bar with the diameter of 25, leaving a first bolt hole in the middle of the 3 pieces of deformed steel bar with the diameter of 25, welding a square cavity and a flat bottom steel plate with the thickness of 4mm, lowering the deformed steel bar with the diameter of 25 to the bottom of the hole for shaking during specific measurement, measuring the length of the steel wire rope, then inserting the deformed steel with the diameter of 25 into the square cavity, penetrating the connecting bolt into the first bolt hole and the second bolt hole, fastening, then placing the connecting bolt down to the hole, when the bottom surface of the flat-bottom steel plate is contacted with the top surface of the sediment, the difference between the measured length of the steel wire rope and the previously measured length is the thickness of the sediment, the locking assembly can be used for fixing the steel wire rope after the first deformed steel bar is placed to the bottom of the hole and the second flat-bottom steel plate is placed to the bottom surface and contacted with the top surface of the sediment, and then the steel wire rope is pulled upwards to carry out two times of steel wire rope lowering length measurement, and the measurement error can be reduced through multiple times of measurement.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
