[0029] Referring to Figures 1 - 3 , the present application relates to a detection device for the sediment thickness of an underwater concrete pile foundation. The detection device includes: a measuring rope 1, a balance circular plate 2 is connected below the measuring rope 1, a main pipe 3 is connected to the bottom of the balance circular plate 2 at the middle position, and at least two slag collection buckets 4 are arranged at equal intervals from top to bottom on the side of the main pipe 3; wherein, the slag collection bucket 4 is used to collect sediment when it enters the sediment layer of the underwater concrete pile foundation.

[0030] Specifically, the measuring rope 1 is used to lift or lower the detection device; the balance circular plate 2 is used to ensure the stability of the detection device to a certain extent; in this embodiment, preferably, the measuring rope 1 includes: a vertical rope and a stay rope. The bottom end of the vertical rope is connected to the balance circular plate 2, and there are multiple stay ropes. One end of the multiple stay ropes is connected to a position near the bottom of the vertical rope, and the other ends are respectively axially connected to positions near the edge of the balance circular plate 2; thus, the stability of lifting or lowering the stay rope can be effectively improved. Preferably, the balance circular plate 2 is a circular thin steel plate; the weight of the detection device can be effectively reduced; it should be understood that the measuring rope 1 can be a nylon rope, a hemp rope or a steel rope. The main pipe 3 has the function of carrying the slag collection bucket 4; the slag collection bucket 4 has the function of collecting sediment when it enters the sediment layer of the underwater concrete pile foundation; in this embodiment, there are at least two slag collection buckets 4, and they are arranged at equal intervals, so that the sediment thickness can be determined by judging which slag collection buckets 4 have sediment; specifically, when the detection device is lowered through the measuring rope 1 into the sediment layer of the pile foundation and the bottom contacts the pile bottom through the mud layer, after a period of time (generally 2 minutes), the measuring rope 1 is lifted to make the detection device come out, and then look down from top to bottom to see from which slag collection bucket 4 there is sediment. Since the distance between each slag collection bucket 4 is the same and the known distance is S, so there are N slag collection buckets 4 counted from this slag collection bucket 4 downwards, and then multiplying N by S can calculate the sediment thickness; the structure of this detection device is simple, the leak-proof valve is omitted, the sediment thickness can be detected very intuitively, and the detection process is also very simple, just count how many slag collection buckets 4 have sediment.

[0031] Preferably, there are five slag collection buckets 4, and the five slag collection buckets 4 are welded in the through holes opened on the side of the main pipe 3; opening through holes on the side of the main pipe 3 and then welding the slag collection buckets 4 into the through holes can effectively improve the connection reliability; further, the distance between two adjacent slag collection buckets 4 is 5 cm, which is convenient for calculating the sediment thickness.

[0032] Preferably, a plurality of balance legs 5 are further provided at the bottom of the balance circular plate 2, and the plurality of balance legs 5 are arranged at equal radian positions near the edge of the balance circular plate 2; the balance circular plate 2 can play a certain role in keeping the detection device balanced, but the effect is not good. Therefore, a plurality of balance legs 5 are also provided to effectively improve the balance effect of the detection device. Further, the number of the balance legs 5 is three, and the three balance legs 5 are welded to the balance circular plate 2; the balance circular plate 2 and the balance legs 5 are welded, which has the characteristic of reliable connection.

[0033] Preferably, the main pipe 3 is welded to the balance circular plate 2; it has the characteristic of reliable connection.

[0034] Preferably, the bottoms of the balance legs 5 and the balance circular plate 2 are conical; the conical balance legs 5 and balance circular plate 2 can facilitate the detection device to enter the sediment layer for detection.

[0035] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
