The specific embodiment
The below will describe various embodiment of the present utility model in detail, and embodiment wherein describes in conjunction with the accompanying drawings and hereinafter.Although the utility model describes in connection with illustrative embodiments, be to be understood that the utility model is not limited to these illustrative embodiments.On the contrary, the utility model not only comprises these embodiments, but also comprises various distortion, improvement.
As shown in Figures 1 to 4, multi-functional hole tester of the present utility model mainly is comprised of aperture support 2, main framing 6, floating plate 10, detecting head 9, the first lining rope 1, the second lining rope 3 and plumb line 4 etc., wherein the length of aperture support 2 is greater than the orifice diameter in stake hole 12, can be fixed on by the ground supports around stake hole 12 place, aperture in a hole 12 during work, the upper end of the first lining rope 1, the second lining rope 3 and plumb line 4 is connected to aperture support 2, and wherein the upper end of the upper end of the first lining rope 1 and plumb line 4 is connected in the roughly same position of aperture support 2.
Described floating plate 10 is suspended to the lower end of the second lining rope 3, the first lining rope 1 extends along the center line of this multi-functional hole tester, detecting head 9 is connected in the lower end of the first lining rope 1 by foot piece 8, and this detecting head 9 is positioned at the below of floating plate 10, and this foot piece 8 passes slidably floating plate 10 and is connected in main framing 6 lower ends.Main framing 6 is suspended to the first lining rope 1 and is positioned at the top of detecting head 9, and the main body of main framing 6 is roughly cylindrical, and it comprises circular boop 5 and reinforcing rib 7.Be equipped with scale on described the first lining rope 1 and the second lining rope 3, the design aperture in the maximum gauge of main framing 6 and this hole 12 is identical, and the density of floating plate 10 is less than the density of stake hole 12 bottom sediments 11, and the density of detecting head 9 is greater than the density of sediment 11.
The operating principle of the multi-functional hole tester of said structure is as follows:
1) Pore Diameter Detection in stake hole
Because the maximum gauge of the main framing 6 of multi-functional hole tester is identical with design stake footpath.Multi-functional hole tester is hung in the process in a hole 12, when main framing 6 relies on the gravity normal descend, illustrate that the effective aperture in a hole 12 is greater than the design aperture; As shown in Figure 4, when main framing 6 is stuck in a hole 12 can not normal descend the time, the effective aperture in explanation stake hole 12 is less than the design aperture.
2) verticality in stake hole detects
Multi-functional hole tester is in dropping process, and the upper end of the first lining rope 1 is fixed in aperture support 2 and a plumb line 4 is set making comparisons at the same position place, and the other end is connected with detecting head 9 on being positioned at multi-functional hole tester center line by foot piece 8.As shown in Figure 3, if fall behind the first lining rope 1 run-off the straight under multi-functional hole tester measure angle between it and plumb line 4 by angle measuring instrument, convert by this angle and can draw the verticality in a hole 12.
3) degree of depth in stake hole and sediment thickness detect
As shown in Figure 2, multi-functional hole tester of the present utility model is mainly to utilize 9 two kinds of different objects of density of floating plate 10 and detecting head, and the principle of a sinking of a floating is measured the thickness of sediment 11.Detecting head 9 adopts the larger material of density to make, and the above is connected with main framing 6 by foot piece 8, and its density is much larger than the density of sediment 11.Floating plate 10 adopts the less materials of density to make, and but its density is less than the density of sediment 11 greater than the density of other media (such as water, mud, air etc.) in stake hole 12.Detecting head 9 is connected with being with graduated the first lining rope 1, the second lining rope 3 respectively with floating plate 10 tops, the zero graduation of the bottom of detecting head 9 during as two lining rope original positions.When this multi-functional hole tester entered interior arrival sediment 11 surface, a hole 12, the surface detecting head 9 that floating plate 10 floats over sediment 11 continued to sink.Detecting head 9 sinks down into and after sediment 11 bottoms reach stable state, the first lining rope 1, the second lining rope 3 is carried out reading, namely be respectively the sediment 11 above hole depth in surface and the sediment 11 above hole depths of bottom, the difference of the first lining rope 1 and the second lining rope 3 readings is the thickness of sediment 11.
The course of work of the multi-functional hole tester of said structure is as follows:
1, multi-functional hole tester is put into a hole 12 and slowly fallen, aperture support 2 is set simultaneously, the first lining rope 1, the second lining rope 3 and plumb line 4 are located at the roughly same position that aperture support 2, the first lining ropes 1 and the end of plumb line 4 are positioned at aperture support 2.
Can the diameter that 2, checks a hole 12 in dropping process allow main framing 6 free-fallings.
3, check in dropping process that can the first lining rope 1 and the angle scaled value of plumb line 4 satisfy the verticality requirement.
4, multi-functional hole tester continues to sink until detecting head 9 sinks to the bottom of sediment 11, and floating plate 10 floats on the upper face of sediment 11.After stable, respectively the first lining rope 1 and the second lining rope 3 are carried out reading, calculate the thickness of sediment 11.
