Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile foundation sediment thickness detection equipment, in particular to a pile foundation sediment thickness detection device. Background Art
[0002] Mechanical rotary drilling piles belong to underground concealed projects. Under most conditions, the wall protection pile-driving technology is not adopted, resulting in the inability to manually drill holes to detect the pile depth and thickness of the pile bottom sediment after the mechanical rotary drilling piles are bored. As an important part of the pile foundation hole quality inspection, whether the bored pile depth meets the design requirements and whether the thickness of the pile bottom sediment meets the specification requirements will directly affect the mechanical properties of the pile after the subsequent pile foundation concrete pouring and the quality of the pile foundation. Therefore, in order to better control the thickness of the pile bottom sediment, the pile depth and pile bottom sediment detection after the pile foundation hole is drilled is particularly important.
[0003] In the prior art, there is no special tool for detecting the thickness of pile foundation sediment. People in the industry determine the amount of sediment at the bottom of the pile based on the geological conditions and the mud content when the drilling rig is cleaning the hole. There is no unified standard and it is impossible to ensure that the sediment thickness meets the design and specification requirements. Most construction units still determine the sediment thickness based on the operator's experience and do not have professional detection tools. This results in large errors and the quality of the pile cannot be guaranteed.
[0004] Therefore, the utility model proposes a pile foundation sediment thickness detection device to solve the above problem. Utility Model Content

[0027] See also Figures 1 to 4 The utility model provides a technical solution: a pile foundation sediment thickness detection device, the pile foundation sediment thickness detection device comprising: a support frame 5, a side block 3 is fixed to the side of the support frame 5, a support column 2 is fixed to the side block 3, a base 4 is fixed to the bottom of the support column 2, and a first vertical plate 1 and a second vertical plate 12 are respectively fixed on both sides of the upper surface of the support frame 5;
[0028] The reel 14 is provided with a lifting rope 13, a scale bar 8 is fixed on the surface of the lifting rope 13, the lower end of the lifting rope 13 is fixedly connected to the connecting plate 18, a limit assembly 16 is provided on the surface of the connecting plate 18, and a measuring cone 15 is provided below the connecting plate 18;
[0029] The side plate 17 is fixed to the surface of the connecting plate 18. A first through hole 25 is opened on the surface of the side plate 17. A limiting rod 24 is inserted into the first through hole 25. A fixing piece 21 is fixed to the end surface of the limiting rod 24. A spring 20 is sleeved on the surface of the limiting rod 24. One end of the spring 20 is fixedly connected to the fixing piece 21, and the other end of the spring 20 is fixedly connected to the side plate 17.

The measuring cone 15 is installed on the connecting plate 18 by using the limit assembly 16 to ensure that the measuring cone 15 is stable and can move up and down freely with the lifting rope 13. The turntable 9 on the end face of the reel 14 is rotated, and the lifting rope 13 is controlled by the handle 10 to adjust the length of the lifting rope 13 so that the initial position of the measuring cone 15 is level with the mouth of the pile foundation pit 6, so as to facilitate subsequent smooth lowering. The lifting rope 13 is slowly released to make the measuring cone 15 steadily descend along the inner wall of the pile foundation pit 6, and the movement of the lifting rope 13 is observed and recorded. The reading of the scale bar 8 is recorded until the measuring cone 15 touches the sediment layer at the bottom of the pile foundation pit 6. After the measuring cone 15 contacts the sediment, it will be more difficult to continue lowering the measuring cone 15 due to the resistance of the sediment. At this time, the lowering is stopped and the lifting rope 13 is locked. The reading of the scale bar 8 on the lifting rope 13 at this moment is recorded, which is the depth of the measuring cone 15 entering the sediment layer. According to the difference in the readings of the scale bar 8 before and after the measuring cone 15 enters the sediment layer, the actual thickness of the sediment at the bottom of the pile foundation pit 6 is calculated, and the measured sediment thickness is compared with the design and specification requirements to determine whether it meets the construction standards. If it exceeds the allowable range, measures must be taken to clean the hole to ensure the quality of the pile foundation project.

The surface of the insert plate 26 is provided with a second through hole 27, and the limiting rod 24 can be inserted into the second through hole 27;
[0035] When in use, the handle 23 is manually turned to draw the limit rod 24 into the first through hole 25 and hold it, and then the plug plate 26 is correspondingly inserted into the slot 19, and the handle 23 is released. Since the first through hole 25 and the second through hole 27 are on the same horizontal line at this time, the limit rod 24 is automatically inserted into the second through hole 27 under the rebound action of the spring 20, so that the measuring cone 15 is effectively positioned.

At this time, the lowering is stopped and Lock the lifting rope 13, record the reading of the scale bar 8 on the lifting rope 13 at this moment, that is, the depth of the measuring cone 15 entering the sediment layer, calculate the actual thickness of the sediment at the bottom of the pile foundation pit 6 according to the difference in the readings of the scale bar 8 before and after the measuring cone 15 enters the sediment layer, compare the measured sediment thickness with the design and specification requirements, and judge whether it meets the construction standards. If it exceeds the allowable range, measures must be taken to clean the hole to ensure the quality of the pile foundation project. This avoids the problem that there is no special tool for pile foundation sediment thickness detection in the prior art. Industry insiders judge the amount of sediment at the bottom of the pile based on the geological conditions and the mud content when the drilling rig cleans the hole. There is no unified standard, and it is impossible to ensure that the sediment thickness meets the design and specification requirements. Most construction units still rely on the operator's experience to determine the sediment thickness, and there are no professional detection tools. This results in a large error, which causes the problem that the quality of the pile cannot be guaranteed.
