Description

Technical Field

[0001] The utility model relates to the technical field of bored pile engineering, in particular to a device for measuring sediment at the bottom of a bored pile hole. Background Art

[0002] The thickness of the sediment at the bottom of the hole in the bored pile project is a very important indicator for detecting bored piles. In traditional bored pile projects, the measurement of sediment thickness usually relies on simple and subjective methods, such as the use of a measuring rope method. This method involves tying a weight to a measuring rope and then manually lowering it to the bottom of the hole, estimating the approximate thickness of the sediment by the feel of lifting and lowering. The accuracy of this practice depends largely on the experience and feeling of the construction workers, so it is easy to produce errors. Utility Model Content

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example

[0020] like Figure 1-Figure 2 As shown, the utility model provides a device for measuring sediment at the bottom of a bored pile hole.

[0021] It includes a positioning plate 1, a measuring rope 2 at the bottom of the hole, a measuring rope 3 on the top surface of the sediment, a lead ball 4, and a nylon mesh bag 6. A measuring rope tube 5 is provided at the axis of the positioning plate 1. The measuring rope tube 5 is hollowed up and down. The nylon mesh bag 6 is sleeved on the lead ball 4. The lower end of the measuring rope 2 at the bottom of the hole is connected to the nylon mesh bag 6. The measuring rope 3 on the top surface of the sediment extends to the bottom of the positioning plate 1 through the measuring rope tube 5. The measuring rope tube 5 can also prevent the positioning plate 1 from tipping over. A buoyancy adjustment hole 7 is provided on the positioning plate 1.

[0022] The positioning plate 1 and the rope measuring tube 5 are configured as an integrally formed structure, or the rope measuring tube 5 is fixedly welded to the positioning plate 1. In this embodiment, the positioning plate 1 and the rope measuring tube 5 are configured as an integrally formed structure, and the integrally formed structure facilitates improving the overall stability;

[0023] The upper and lower heights of the rope measuring tube 5 are set to 4-6 cm, which can be set according to actual needs, and the height is not unique. The left and right widths of the rope measuring tube 5 are set to 0.5-2 cm, which can be set according to actual needs, and the width is not unique, so that the device can adapt to drilling holes of different diameters and depths;

[0024] The bottom hole measuring rope 2 and the sediment top surface measuring rope 3 are both provided with scale lines;

[0025] The diameter of the buoyancy adjustment hole 7 is set to 0.5-2 cm, which can be set according to actual needs. The diameter is not unique, so that the device can adapt to drilling holes of different diameters and depths;

[0026] The cross section of the positioning plate 1 is set to a circular structure, or the cross section of the positioning plate 1 is set to a rectangular structure, which can be set according to actual needs;

[0027] The utility model comprises the following steps during use:

[0028] 1. Preparation stage:

[0029] Nylon mesh bag 6 containing lead ball 4: This is a weight used to ensure that the measuring rope can reach the bottom of the hole.

[0030] Hole bottom measuring rope 2: This is a rope used to measure the depth of the hole bottom.

[0031] Sediment top measuring rope 3: This is another rope used to measure the depth of the top of the sediment layer.

[0032] 2. Operation steps:

[0033] Connect the nylon mesh bag 6 to the measuring rope 2 at the bottom of the hole and pass it through the measuring rope tube 5 of the positioning plate 1.

[0034] Measure and record the length from the lead ball 4 to the connection point, which is for the subsequent calculation of the sediment thickness.

[0035] The sediment top surface measuring rope 3 is also passed through the positioning plate 1 to prepare for measurement.

[0036] 3. Measurement steps:

[0037] Sink the lead ball 4 into the bottom of the hole so that the bottom measuring rope 2 reaches the bottom.

[0038] Place the positioning disc 1 into the hole. This positioning disc 1 helps to keep the measuring rope in a vertical state.

[0039] Keep the measuring rope 2 at the bottom of the hole and the measuring rope 3 on the top surface of the sediment vertical to ensure the accuracy of the measurement.

[0040] 4. Read data:

[0041] Read the bottom hole line 2 data, this will give the depth of the bottom of the hole.

[0042] Read the top of the sediment line 3, this will give the depth of the top of the sediment.

[0043] 5. Calculate sediment thickness:

[0044] The thickness of the sediment is calculated using two data points, the depth to the bottom of the hole and the depth to the top of the sediment.

[0045] When the utility model is in use, the lead ball 4 and the nylon mesh bag 6 will sink into the water until they touch the bottom of the hole. At this time, the scale lines of the hole bottom measuring rope 2 can help determine the exact position where the lead ball 4 touches the bottom. Then, the sediment top surface measuring rope 3 will extend from below the positioning plate 1 and reach the top surface of the sediment through the measuring rope tube 5. Due to the scale lines of the sediment top surface measuring rope 3, the position of the sediment top surface can be accurately read, thereby ensuring the construction quality.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
