Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and relates to a tool for detecting the thickness of cast-in-place pile sediment. Background Art

[0002] With the development of economy, there are more and more high-rise buildings, and the application of underwater cast-in-place piles is becoming more and more common. The thickness of pile bottom sediment is one of the main factors affecting the vertical bearing capacity of pile foundation. Too thick pile bottom sediment can easily cause the foundation settlement to exceed the design value, thus causing safety and quality accidents.

[0003] Since the sediment at the bottom of the pile is located underwater and cannot be seen by visual inspection, although there are very advanced sediment measuring instruments, they are expensive and can only be used for random inspections in important projects, and have not yet been popularized. In addition, when the current measuring tools are inserted into the sediment, their verticality cannot be ensured, resulting in frequent discrepancies in the measured values. Multiple measurements are required, which is inefficient, and the actual data of the sediment thickness is not clear, which can cause misjudgment. Utility Model Content

A guide through hole is provided on the pressure plate, and the insertion rod is slidably installed in the guide through hole.

[0011] Beneficial effects:

[0012] 1. In the utility model, the thickness of the sediment can be measured conveniently and quickly through the arrangement of the first large reel, the second large reel, the pressure plate, the insertion rod, the rotating handle, the wire rope, the limit rod and the limit hole. Combined with the arrangement of the guide through hole and the sliding installation of the insertion rod in the guide through hole, the verticality of the insertion rod into the sediment can be ensured, so that the measurement data is more accurate. At the same time, there is no need for repeated measurements, and the measurement efficiency is high. Specifically, when in use, the support frame is first fixedly installed above the pile hole, and the wire ropes on the first large reel and the second large reel are respectively connected with the insertion rod and the pressure plate to ensure that the two wire ropes are as close to the center of the pile hole as possible. Then the insertion rod is slidably matched with the guide through hole on the pressure plate, and the limit rod is matched with the limit hole, so that the first large reel and the second large reel are in the effect of the rotating handle. The handle is then turned to release the wire rope, until the bottom of the plunger is in contact with the lower surface of the sediment, and the distance between the lower surface of the sediment and the first large reel is confirmed by adding the length of the wire rope released from the first large reel and the length of the plunger. Finally, the thickness of the sediment can be obtained by the difference between the two distances. In this process, two wire ropes can be released synchronously to measure two sets of data respectively, which can reduce the time required for separate measurements. In addition, under the restrictions of the pressure plate and the guide through hole, the angle at which the plunger enters the sediment is always vertical.

[0013] 2. In the utility model, the setting of the hanger, the perforation and the limit of the hanger connection position can prevent the pressure plate from being deflected when being lowered, ensuring that the pressure plate is in horizontal contact with the sediment, so that the entry angle of the insertion rod is vertical, further making the measurement data more accurate, and also facilitating the calculation of the distance between the bottom end of the wire rope and the lower surface of the pressure plate, which is part or all of some other fixed data.

[0014] 3. In the present invention, multiple guide holes and multiple matching insertion rods are provided, so that multiple sets of data can be measured simultaneously. By taking the average value of the multiple sets of data, errors can be reduced and the measurement accuracy can be further improved.

[0015] 4. In the present invention, the limiting rod and the limiting hole are respectively located at the center of the first large reel and the second large reel, which can facilitate the rapid coordination of the two. At the same time, the limiting rod can be used to improve the supporting strength between the first large reel and the second large reel.

[0016] 5. In the utility model, the setting of the limit block and its position restriction can prevent the insertion rod from detaching from the pressure plate from above when the first reel rotates alone, ensuring that the insertion rod is always relatively vertical to the pressure plate under the guiding limit of the guide through hole. In addition, the lifting of the limit block can also be used to drive the pressure plate to move up synchronously; by setting the scale dimension line, the release length of the wire rope can be quickly read.

[0017] 6. In the present invention, the position of the two steel wire ropes can be limited by setting the limit ring, ensuring that the pressure plate and the insertion rod move along the center of the pile hole, avoiding the pressure plate from touching the inner wall of the pile hole, and further improving the measurement accuracy.

[0030] The utility model provides a tool for detecting the thickness of cast-in-place pile sediment. Figure 1 , Figure 2 and Figure 3 As shown, it includes a support frame 1 installed above the pile hole, a winding wheel assembly, a pressure plate 2 and an insertion rod 3, wherein the pressure plate 2 can float on the surface of the sediment, and the insertion rod 3 can be quickly inserted into the sediment. In order to prevent the influence of water accumulation above the sediment on the contact between the pressure plate 2 and the sediment, a water hole 13 can be appropriately opened on the pressure plate 2. The winding wheel assembly is rotatably installed on the support frame 1. The winding wheel assembly is respectively connected to the pressure plate 2 and the insertion rod 3 through a wire rope 9. The winding wheel assembly includes a first large winding wheel 4, a second large winding wheel 5, a rotating handle 6 and a limiting rod 7. The diameters of the first large winding wheel 4 and the second large winding wheel 5 are equal, and they are relatively spaced. The first large winding wheel 4 and the second large winding wheel 5 are respectively connected to the support frame through a rotating shaft 1 is rotatably connected on both sides, the rotating handle 6 is installed on one side of the support frame 1 and is fixedly connected to the rotating shaft of the first large reel 4, the limiting rod 7 is slidably installed at the end of the first large reel 4 away from the rotating handle 6, and the second large reel 5 is provided with a limiting hole 8 corresponding to the limiting rod 7. When the limiting rod 7 cooperates with the limiting hole 8, the first large reel 4 and the second large reel 5 rotate synchronously under the drive of the rotating handle 6, otherwise the second large reel 5 does not rotate, the pressing plate 2 is provided with a guide through hole 21, the insertion rod 3 is slidably installed in the guide through hole 21, the first large reel 4 is fixedly connected to the insertion rod 3 through a steel wire rope 9, and the second large reel 5 is fixedly connected to the pressing plate 2 through a steel wire rope 9.

[0031] The slag thickness can be measured conveniently and quickly by setting the first large reel 4, the second large reel 5, the pressure plate 2, the insertion rod 3, the rotating handle 6, the wire rope 9, the limiting rod 7 and the limiting hole 8. Combined with the guide through hole 21 and the setting that the insertion rod 3 is slidably installed in the guide through hole 21, the verticality of the insertion rod 3 in the sediment can be ensured, making the measurement data more accurate. At the same time, there is no need for repeated measurements, and the measurement efficiency is high. The setting of the large reel can speed up the efficiency of retracting and releasing the wire rope 9, thereby indirectly improving the measurement efficiency. Specifically, when in use, the support frame 1 is first fixedly installed above the pile hole, and the wire ropes 9 on the first large reel 4 and the second large reel 5 are respectively connected with the insertion rod 3 and the pressure plate 2 to ensure that the two wire ropes 9 are as close to the center of the pile hole as possible. Then the insertion rod 3 is slidably matched with the guide through hole 21 on the pressure plate 2, and the limiting rod 7 is matched with the limiting hole 8, so that the first A large reel 4 and a second large reel 5 rotate synchronously under the action of the rotating handle 6 and release the wire rope 9 until the contact between the pressure plate 2 and the upper surface of the sediment is stopped. At this time, the distance between the upper surface of the sediment and the second large reel 5 can be confirmed by the length of the wire rope 9 released on the second large reel 5 and some other fixed data. Then the cooperation between the limit rod 7 and the limit hole 8 is released, and the wire rope 9 continues to be released by rotating the handle 6 until the bottom of the insertion rod 3 is stopped from contacting the lower surface of the sediment. At this time, the distance between the lower surface of the sediment and the first large reel 4 can be confirmed by the length of the wire rope 9 released on the first large reel 4 plus the length of the insertion rod 3. Finally, the thickness of the sediment can be obtained by the difference between the two distances. In this process, two wire ropes 9 can be released synchronously to measure two sets of data respectively, which can reduce the time required for separate measurement. In addition, under the restriction of the pressure plate 2 and the guide through hole 21, the angle at which the insertion rod 3 enters the sediment is always vertical.

[0032] In the present invention, preferably, Figure 1 and Figure 2 As shown, a hanger 10 is provided on the pressure plate 2, and the connection points between the hanger 10 and the pressure plate 2 are symmetrically arranged at the edge of the pressure plate 2. A through hole is provided at the center of the hanger 10, and the steel wire rope 9 on the first large reel 4 passes through the through hole and is fixedly connected to the inserted rod 3, and the steel wire rope 9 on the second large reel 5 is fixedly connected to the edge of the through hole.

[0033] In this embodiment, the hanger 10, the perforations and the connection position restrictions of the hanger 10 can prevent the pressure plate 2 from tilting when being lowered, ensuring that the pressure plate 2 is in horizontal contact with the sediment, thereby making the entry angle of the insertion rod 3 vertical, further making the measurement data more accurate, and also facilitating the calculation of the distance between the bottom end of the wire rope 9 and the lower surface of the pressure plate 2, which is part or all of some other fixed data.

[0034] In the present invention, preferably, Figure 1 and Figure 2As shown, the guide through hole 21 includes a plurality of guide through holes 21 which are symmetrically arranged about the center of the pressure plate 2. The insertion rods 3 correspond to the guide through holes 21 one by one. The plurality of insertion rods 3 are fixedly connected to the steel wire rope 9 through auxiliary ropes. When an auxiliary rope is present, in order to ensure the measurement accuracy, the distance between the top end of the insertion rod 3 and the bottom end of the steel wire rope 9 needs to be calculated. When the steel wire rope 9 tightens the insertion rod 3, this distance is a constant, so it can be calculated in advance.

[0035] In this embodiment, by providing a plurality of guide through holes 21 and a plurality of matching insertion rods 3, a plurality of groups of data can be measured simultaneously. By taking the average value of the plurality of groups of data, the error can be reduced and the measurement accuracy can be further improved.

[0036] In the present invention, preferably, Figure 1 and Figure 3 As shown, the limiting rod 7 and the limiting hole 8 are located at the center of the first large reel 4 and the second large reel 5 respectively.

[0037] In this embodiment, by arranging the limiting rod 7 and the limiting hole 8 at the center of the first large reel 4 and the second large reel 5 respectively, the two can be quickly matched, and the limiting rod 7 can be used to improve the supporting strength between the first large reel 4 and the second large reel 5.

[0038] In the present invention, preferably, Figure 1 and Figure 2 As shown, a limit block 11 is provided on the insertion rod 3, and the size of the limit block 11 is larger than the diameter of the guide through hole 21. The limit block 11 is located below the pressure plate 2. In actual use, in order to reduce measurement data and errors, the thickness of the sediment can be directly calculated by using the length of the wire rope 9 that the first large reel 4 continues to lower after the pressure plate 2 contacts the upper surface of the sediment, the length of the insertion rod 3, and the distance from the top end of the limit block 11 to the bottom end of the wire rope 9. This calculation method can avoid the error existing in the synchronous release process of the first large reel 4 and the second large reel 5. Specifically, before the limit rod 7 and the limit hole 8 cooperate, ensure that the limit block 11 is in contact with the bottom surface of the pressure plate 2. Suppose the total length of the insertion rod 3 is H, the distance from the top end of the limit block 11 to the bottom end of the wire rope 9 is h, and the length of the wire rope 9 that the first large reel 4 continues to lower after the pressure plate 2 contacts the upper surface of the sediment is L, then the thickness of the sediment S=H-h+L.

[0039] In this embodiment, the setting of the limit block 11 and its position restriction can prevent the insertion rod 3 from detaching from the pressure plate 2 from above when the first reel rotates alone, ensuring that the insertion rod 3 is always relatively vertical to the pressure plate 2 under the guiding limit of the guide through hole 21. In addition, the lifting of the limit block 11 can also be used to drive the pressure plate 2 to move upward synchronously, and at the same time, the weight of the insertion rod 3 can be increased, thereby increasing the speed at which the long rod 3 is inserted into the sediment.

[0040] In the present invention, preferably, Figure 1 As shown, the steel wire rope 9 is provided with scale lines.

[0041] In this embodiment, the release length of the steel wire rope 9 can be quickly read by setting the scale dimension lines.

[0042] In the present invention, preferably, Figure 1 and Figure 3 As shown, the support frame 1 is also provided with a limiting ring 12, which is coaxially arranged with the pile hole and located below the large reel. The two steel wire ropes 9 pass through the limiting ring 12 and are fixedly connected to the pressure plate 2 and the insertion rod 3 respectively.

[0043] In this embodiment, by setting the limit ring 12, the positions of the two steel wire ropes 9 can be limited, ensuring that the pressure plate 2 and the insertion rod 3 move along the center of the pile hole, avoiding the pressure plate 2 from touching the inner wall of the pile hole, and further improving the measurement accuracy.

[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
