Abstract
The utility model provides a bored pile sediment thickness measuring cylinder, which belongs to a measuring instrument. The bored pile sediment thickness measuring cylinder is characterized in that the measuring cylinder is mainly formed by assembly welding a main shaft pipe and accessory measuring cylinders. The accessory measuring cylinders each provided with a bottom are uniformly circumferentially welded on the periphery of the main shaft pipe from the bottom of the main shaft pipe to the top in a spiral way. The spiral angle is 22.5 DEG. Preferably, eight accessory measuring cylinders are welded on each spiral cycle on the periphery of the main shaft pipe. The main shaft pipe is a steel pipe which has a height of 600mm and a diameter phi of 60mm * 3.5mm. Each accessory measuring cylinder is a steel-pipe cylinder which has a height of 20mm, a diameter phi of 22mm * 2.5mm and an inner diameter depth of 19mm. A lifting rope is tied on a tie bar which is welded on the top surface of the main shaft pipe. When lifted inside a pile hole, the measuring cylinder is sunk into the hole bottom by the tubular structure and enough deadweight of itself. Then the accessory measuring cylinders on the periphery are applied for sampling the sediment. The thickness value of the sediment on the pile hole bottom is obtained by the height value of a highest accessory measuring cylinder with the sediment and the estimation value of the height of the sediment in the highest accessory measuring cylinder. The bored pile sediment thickness measuring cylinder is convenient to use and direct-viewing as well as accurate in measurement.
Description
Technical field
The utility model belongs to measuring appliance, especially relates to a kind of measurement tube of bored pile.
Background technology
At present, the common measuring method of sedimentary thickness in the bored pile is: when bored pile boring is finished, earlier measure its degree of depth I with lining rope and sash weight, measuring its degree of depth II again with lining rope and sash weight before the concrete perfusion behind the clear hole then, get the difference of degree of depth II and degree of depth I, be the thickness of sediment, but the error of surface layer location during owing to lining rope and measurement, make the sedimentary thickness measure degree of accuracy be subjected to very big influence, can not realize disposable measurement more accurately, other detection method also has the electronic instrument detection method, but cost is higher, and be subjected to the influence and the restriction of external environment condition, complicated operation.
Summary of the invention
The purpose of this utility model provides a kind of measurement tube of bored pile sediment thickness, makes the measurement of sediment thickness more directly perceived accurately, simple in structure, does not need complicated electronic equipment, and is not affected by environment, makes easily, and cost is low, and is easy to operate.
The purpose of this utility model is achieved like this: a kind of measurement tube of bored pile sediment thickness, the measurement tube that it is characterized in that this bored pile sediment thickness is mainly formed by spindle tube and each secondary graduated cylinder assembly welding, the periphery of spindle tube from the bottom of spindle tube the line ground circumference uniform distribution band secondary graduated cylinder at the end that is welded in the shape of a spiral from bottom to top, the angle of this helix can be 22.5 °, and with uniform eight the secondary graduated cylinders that are welded on each all helix of spindle tube periphery is good, this spindle tube is the steel pipe of Φ 60mm * 3.5mm of high 600mm, Φ 22mm * 2.5mm that this pair graduated cylinder is high 20mm and internal diameter are the steel pipe tube of 19mm deeply, in addition, be welded tie-rod and be the dress lifting rope on the top end face of spindle tube on this tie-rod, this tie-rod can be round steel, so that this measurement tube is hung in priming concrete pile hole, during use, this measurement tube is hung in priming concrete pile hole, the tubular structure of dependence device itself and enough deadweights are sunk to this device at the bottom of the hole, secondary graduated cylinder around utilizing is taken a sample to sediment, after sampling comes up, measure the highest height that sedimentary secondary graduated cylinder is housed with invar tape, the sedimentary height that is equipped with in the highest sedimentary secondary graduated cylinder is estimated, get height value that the highest secondary graduated cylinder of sediment is housed and estimated value and calculate, promptly draw sedimentary one-tenth-value thickness 1/10 at the bottom of the priming concrete pile hole.
The measurement tube of the bored pile sediment thickness that the utility model proposed, simple in structure, easy to use, it is more directly perceived accurate to measure.
Now in conjunction with the accompanying drawings and embodiments the measurement tube of the bored pile sediment thickness that the utility model proposed is described further.
