Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation construction, and specifically to a device for measuring the sediment thickness of bored piles. Background Technique

[0002] Due to the advantages of no vibration, no soil extrusion, low noise during construction and being suitable for use in areas with dense urban buildings, cast-in-place piles are widely used in the construction of high-rise buildings, important structures and buildings with large loads. During the hole-forming process of cast-in-place pile construction, falling quicksand, crushed stones, etc. will precipitate at the bottom of the hole to form sediment. The sediment at the bottom of the hole has characteristics such as low strength and high compressibility. The existence of the sediment at the bottom of the hole will change the bearing performance of the cast-in-place pile and affect the exertion of the bearing capacity of the bored cast-in-place pile. Therefore, only by controlling the sediment thickness within a reasonable range can the overall quality of the pile foundation be ensured.

[0003] At present, the detection of the sediment thickness of pile holes mainly adopts the measuring rope method, that is, a measuring needle is connected by a measuring rope, and the measuring needle is lowered to the bottom of the hole to measure the depth of the bottom of the hole. Then, a measuring cake is connected by the measuring rope, and the measuring cake is lowered to the top surface of the sediment to measure the depth of the top surface of the sediment. The difference between the two is the sediment thickness.

[0004] In view of the above-mentioned existing related technologies, when measuring bored piles with relatively large diameters, due to their large area, there is easily a phenomenon of uneven sediment thickness. Therefore, multi-point measurement is required to ensure the accuracy of sediment thickness detection.

[0005] In order to address the above problems, there is an urgent need for a device for measuring the sediment thickness of bored piles. Content of the Utility Model

[0006] The purpose of the utility model is to provide a device for measuring the sediment thickness of bored piles to solve the problems raised in the above background technique.

[0007] To achieve the above purpose, a device for measuring the sediment thickness of bored piles is provided, which includes a moving frame, a measuring component and an adjusting component. The moving frame includes an upper ring beam and a lower ring beam, which are connected by a plurality of lifting rods. Among them, a plurality of telescopic support frames are provided on the outer wall of the lower ring beam, and several of the support frames can be adjusted individually according to actual needs, while the plurality of lifting rods are adjusted synchronously to adjust the height between the upper ring beam and the lower ring beam;

[0008] The adjusting component includes a rotating shaft, a suspension beam and an upper reel. The rotating shaft is fixed at the center of the upper ring beam through a bracket. The suspension beam is fixedly connected to the rotating shaft and can rotate with the rotating shaft. The upper reel is slidably installed on the suspension beam;

[0009] The measurement component includes a measurement disc and a measurement needle. The measurement disc is hoisted on the upper reel through a rope. A syringe barrel is arranged on the measurement disc. A lower reel is installed at the top of the syringe barrel. The measurement needle is installed on the lower reel through a rope, and the measurement needle can pass through the syringe barrel and reach the measurement disc. After the measurement disc stably lands on the surface of the sediment, the thickness of the sediment can be obtained by calculating the falling height of the measurement needle.

[0010] Further, one end of the cantilever is connected to the bottom of the rotating shaft, and the other end is provided with an "L"-shaped hook. An annular groove is formed on the inner ring wall of the upper ring beam. The other end of the cantilever is lapped in the groove through the hook. The hook can play a role in lifting and pulling the cantilever with the help of the upper ring beam, protecting the rotating shaft and the cantilever from deformation and damage.

[0011] Further, a chute is formed at the top of the cantilever. The two ends of the upper reel are provided with lifting wheels upward. The lifting wheels can slide in the chute. The main function of the chute here is to limit the position and prevent the upper reel from running off track.

[0012] Further, several equidistantly arranged hanging rings are provided on the measurement disc. The upper reel is connected to the hanging rings through suspension ropes. There are three hanging rings in total. The connection lines between the three form an equilateral triangle, and each hanging ring is at the vertex position. In this way, the stability of the measurement disc can be ensured. The syringe barrel is located at the center of the measurement disc. The syringe barrel is a tubular structure with openings at both the upper and lower ends. An opening corresponding to the syringe barrel is formed at the center of the measurement disc.

[0013] Further, the upper reel and the lower reel are both equipped with corresponding electric motors. The lower reel is also equipped with an angle measuring instrument for measuring its rotation angle.

[0014] Further, the number of the support frames is at least three, and universal wheels are installed at the telescopic ends of the support frames.

[0026] Please refer to Figures 1-4 As shown, a device for measuring the sediment thickness of bored piles is provided, which includes a moving frame, a measuring component and an adjusting component. The moving frame includes an upper ring beam 1 and a lower ring beam 2, which are connected by a plurality of lifting rods 3. The outer wall of the lower ring beam 2 is provided with a plurality of telescopic support frames 4, and several of the support frames 4 can be adjusted separately according to actual needs, while the plurality of lifting rods 3 are adjusted synchronously to adjust the height between the upper ring beam 1 and the lower ring beam 2.

[0027] The adjusting component includes a rotating shaft 5, a suspended beam 6 and an upper reel 7. The rotating shaft 5 is fixed at the center of the upper ring beam 1 through a bracket. The suspended beam 6 is fixedly connected to the rotating shaft 5 and can rotate with the rotating shaft 5. The upper reel 7 is slidably installed on the suspended beam 6;

[0028] It should be noted that reference can be made to Figures 1-4The position change of the middle suspension beam 6 and the height change of the entire device; the position change of the suspension beam 6 includes different rotation angles and also includes the position change of the measuring component on the suspension beam 6.

[0029] The measuring component includes a measuring disc 8 and a measuring needle 9. The measuring disc 8 is hoisted on the upper winding drum 7 by a rope. A syringe barrel 10 is arranged on the measuring disc 8. A lower winding drum 11 is installed at the top of the syringe barrel 10. The measuring needle 9 is installed on the lower winding drum 11 by a rope, and the measuring needle 9 can pass through the syringe barrel 10 and the measuring disc 8; after the measuring disc 8 stably lands on the surface of the sediment, calculating the falling height of the measuring needle 9 can obtain the thickness of the sediment.

[0030] Refer to Figures 1-3 as shown in

[0031] One end of the suspension beam 6 is connected to the bottom of the rotating shaft 5, and the other end is provided with an "L"-shaped hook 12. An annular groove 13 is opened on the inner ring wall of the upper ring beam 1. The other end of the suspension beam 6 is lapped in the groove 13 through the hook 12. The hook 12 can support the suspension beam 6 with the help of the upper ring beam 1 to protect the rotating shaft 5 and the suspension beam 6 from being deformed and damaged; it is worth mentioning that the groove 13 here can also be replaced by a protruding annular structure.

[0032] Please combine with Figure 1 and Figure 2 as shown in

[0033] A chute 14 is opened at the top of the suspension beam 6. The two ends of the upper winding drum 7 are provided with lifting wheels 15 upward. The lifting wheels 15 can slide in the chute 14. The main function of the chute 14 here is to limit the position to prevent the upper winding drum 7 from running off track. During the specific use process, the specific position of the measuring component can be adjusted through the lifting wheels 15 and the rotating shaft 5, so as to perform multiple tests on the sediment thickness inside the large bored pile to improve the accuracy of the sediment thickness detection;

[0034] As Figure 3 shown in

[0035] The measuring disc 8 is provided with several equally spaced hanging rings 16. The upper winding drum 7 is connected to the hanging rings 16 by a suspension rope. The number of the hanging rings 16 is three in total. The connection lines between the three form an equilateral triangle, and each hanging ring 16 is at the vertex position, so as to ensure the stability of the measuring disc 8; the syringe barrel 10 is located at the center of the measuring disc 8. The syringe barrel 10 is a tubular structure with openings at both the upper and lower ends. An opening corresponding to the syringe barrel 10 is opened at the center of the measuring disc 8; both the upper winding drum 7 and the lower winding drum 11 are equipped with corresponding electric motors. The lower winding drum 11 is also equipped with an angle measuring instrument for measuring its rotation angle; the number of the support frames 4 is at least three, and universal wheels are installed at the telescopic ends of the support frames 4.

[0036] Working principle:

[0037] During actual use, the height of the entire device can be adjusted by adjusting the lifting rod 3 according to the operator's height. When the diameter of the bored pile is large, the support frame 4 can also be stretched to place the device above the bored pile;

[0038] During measurement, the cantilever 6 can rotate through the rotating shaft 5, so the entire measurement assembly can rotate following the rotation of the cantilever 6; moreover, the measurement assembly can also adjust its position on the cantilever 6 through the pulley 15. From the above description, it can be seen that the measurement assembly in this device can almost measure all areas within the inner diameter of the upper ring beam 1, and the position adjustment is simple and fast;

[0039] During measurement, first lower the measuring disc 8 through the upper reel 7. When the measuring disc 8 stably lands on the surface of the sediment, lower the measuring needle 9 through the lower reel 11. Here, the measuring needle 9 is made of stainless steel, and its bottom is conical. Due to the large self-weight and sharp bottom of the measuring needle 9, it can continue to sink. When the measuring needle 9 stops moving, it means that the measuring needle 9 has touched the relatively hard soil layer. At this time, as long as the sinking distance of the measuring needle 9 is calculated, the thickness of the sediment can be obtained;

[0040] For the convenience of measurement, an angle measuring instrument is configured on the lower reel 11, and the sinking distance of the measuring needle 9 can be obtained by calculating the rotation angle of the lower reel 11.

[0041] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
