Description

Technical Field

[0001] The utility model relates to the technical field of bored pile construction, in particular to a bored pile sediment thickness detection device. Background Art

[0002] Excessive sediment at the bottom of the pile is primarily caused by incomplete hole cleaning or a failure to perform secondary hole cleaning during construction. During construction, after the bored pile is bored, the drill bit should be elevated 10-20 cm above the hole bottom, kept in slow, idling motion, and maintained for at least 30 minutes of continuous hole cleaning. Then, a hammer grab should be slowly lowered into the hole to remove the sediment. If the slurry used is too light or the amount of slurry injected is insufficient, sediment at the bottom of the pile will be difficult to float and will accumulate at the bottom, affecting the connection between the pile and the foundation.

[0003] Therefore, the thickness of pile bottom sediment is a key indicator of pile foundation quality. The standard stipulates that the thickness of pile bottom sediment should not exceed 50mm for end-bearing piles and 100mm for friction piles. Currently, the method for measuring sediment thickness primarily uses a hammer, with the difference between two measured values ​​being used as the sediment thickness. This method has poor accuracy, requires more experience, and is subject to significant uncertainty. Utility Model Content

[0028] This embodiment provides a bored pile sediment thickness detection device, which can detect the sediment thickness in the borehole, has simple operation, high accuracy, and intuitive test results.

[0029] Specifically, see Figures 1-4 A bored pile sediment thickness detection device includes a winch 1, a probe 2, a data line 3 and a communication host 4, wherein the winch 1 is used to release or retract the probe 2, the probe 2 is used to detect the resistivity and its own inclination in real time, the data line 3 is used to transmit the detection data of the probe 2 to the communication host 4, and the communication host 4 processes the information to generate a sediment graph, which directly displays the sediment thickness and the change in the resistance of the medium around the probe 2. When the probe 2 detects a change in its own inclination, it means that the probe 2 has contacted the bottom of the hole. The sediment thickness is directly obtained through the sediment graph, and the test is completed.

[0030] Preferably, a bored pile sediment thickness detection device further comprises a printer (not shown in the figure), which is connected to the communication host 4. After the test is completed, the test report generated by the communication host 4 is directly printed by the printer, and the test report is automatically generated.

[0031] Furthermore, the winch 1 in this embodiment is a manual winch 1 , and the moving speed and direction of the probe 2 are controlled by hand cranking.

[0032] Specifically, the data line 3 is wound around the winch 1 , and one end of the data line 3 is connected to one end of the probe 2 , and the other end of the data line 3 is connected to the communication host 4 .

[0033] See also Figure 1 During the test, the probe 2 is first placed vertically in the borehole 100, and the data line 3 is further released by the hand winch 1. The probe 2 gradually extends into the borehole 100. During this process, the probe 2 detects the resistivity and its own inclination in real time, and transmits the detection data to the communication host 4 via the data line 3. The communication host 4 can display the data in real time until the probe's own inclination changes significantly, indicating that the other end of the probe 2 has touched the bottom of the hole. The communication host 4 forms a sediment graph, and the sediment thickness is directly derived from the sediment graph. The test is completed, and the test report is directly printed by the printer. In addition, the data line 3 is reeled in by the hand winch 1 in the opposite direction, and the probe 2 gradually rises and extends out of the borehole 100.

[0034] Further, see Figure 2 , a communication cable is set at one end of the probe 2 close to the winch 1, and the communication cable is connected to the data line 3. The communication cable is a high-strength tensile special cable to prevent the data line 3 from breaking and affecting data transmission.

[0035] It should be noted that the probe 2 analyzes the sediment thickness at the bottom of the borehole 100 by detecting the dielectric resistance value between each two detection rings. An angle inclination sensor is provided inside the probe 2, and the angle inclination sensor is connected to the communication cable. The inclination angle of the probe 2 is obtained through the angle inclination sensor and transmitted to the communication host 4 through the communication cable and data line 3, and displayed in real time by the communication host 4.

[0036] Furthermore, the communication host 4 includes a lithium battery, a receiving device and a transmitting device, etc., and is used in conjunction with a computer to display test data in real time, control the test process, and analyze data.

[0037] The bored pile sediment thickness detection device also includes a frame 6. Specifically, the frame 6 includes a top plate, a bottom plate and two opposite side plates, wherein the winch 1 is installed inside the frame 6. The winch 1 can be manually cranked by inserting a hand into the frame 6 from the side. The communication host 4 is installed on the top plate of the frame 6 to form an integrated structure for easy mobile use.

[0038] Preferably, the frame 6 is made of stainless steel, which can adapt to various environments.

[0039] Optionally, see Figure 2 Both ends of the winch 1 are provided with connecting rods 8, and the two connecting rods 8 are respectively fixed on opposite sides of the frame 6, that is, the two side plates of the frame 6.

[0040] Further preferably, the top plate of the frame 6 is provided with a handle 7. The bored pile sediment thickness detection device provided in this embodiment is lightweight and can be moved and used by one person by providing the handle 7. Optionally, two handles 7 can be provided opposite to each other for holding with both hands.

[0041] For example, a clamping member 9 is provided on the top plate of the frame 6 , and in the standby state, the probe 2 can be clamped on the clamping member 9 to prevent accidental damage.

[0042] Specifically, two clamping members 9 are provided, and the two clamping members 9 are spaced apart and arranged on the top plate of the frame 6 .

[0043] Optionally, see Figure 4 The clamping member 9 includes a first limiting portion 91 and a second limiting portion 92. The first limiting portion 91 and the second limiting portion 92 cooperate to form a limiting space for accommodating and limiting the position of the probe 2. One end of the first limiting portion 91 is connected to the top plate, and the other end of the first limiting portion 91 is connected to the second limiting portion 92 after being bent into an arc. The second limiting portion 92 is set to a certain value and can press against the probe 2, thereby limiting the position of the probe 2.

[0044] This embodiment provides a bored pile sediment thickness detection device:

[0045] During the detection process, the probe 2 is first removed from the clamping member 9, and the probe 2 is placed vertically in the borehole 100. The data line 3 is further released by the hand winch 1, and the probe 2 is gradually extended into the borehole 100. During this process, the probe 2 detects the resistivity and its own inclination in real time, and transmits the detection data to the communication host 4 through the communication cable and the data line 3. The communication host 4 can display the data in real time until the inclination changes significantly, indicating that the other end of the probe 2 has touched the bottom of the hole. A sediment graph is formed by the communication host 4, and the sediment thickness is directly obtained from the sediment graph. The detection is completed, and a test report is directly printed by the printer;

[0046] After the test is completed, the data cable 3 is wound up by the reverse hand winch 1, and the probe 2 gradually rises and extends out of the borehole 100. The probe 2 is clamped on the clamping piece 9 on the top plate of the frame 6, and the data cable 3 is kept taut.
