Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering monitoring, in particular to a pile hole sediment thickness detection device. Background Art
[0002] After the bored pile is formed, the thickness of the mud residue and soil residue at the bottom of the pile hole needs to be tested. The quality standards vary according to the type of pile. The most commonly used measurement method is the probe-cake method. When measuring, first lower the probe, let the probe pass through the sediment and contact the bottom of the pile hole, and measure the depth as the hole bottom depth; then lower the cake, let the lower surface of the cake contact the top of the sediment, and measure the depth as the sediment top depth. The difference between the two data is the sediment thickness.
[0003] The above-mentioned measuring method of measuring with a probe and a cake has the following disadvantages: when the probe is lowered through a connecting line, the connecting line is relatively soft. If the sediment is relatively dense, it is difficult for the probe to pass through the sediment and contact the bottom of the pile hole at one time. The connecting line needs to be repeatedly pulled up and down to allow the probe to pass through the sediment. Therefore, during the measurement process, it cannot be guaranteed that the probe will contact the bottom of the pile hole at one time. Secondly, when the measuring cake is lowered, the measuring cake will also shake with the connecting box, resulting in a relatively long entire measuring process and possible errors in the measurement. Therefore, the utility model proposes a pile hole sediment thickness detection device. Utility Model Content

[0023] like Figure 1 As shown, the bottom end of the measuring needle 2 is designed as a pointed tip, so that after the measuring needle 2 is inserted into the pile hole, the bottom of the measuring needle 2 can more easily pass through the sediment.
[0024] like Figure 1-Figure 3 As shown, the top of the measuring needle 2 and the top of the guide rod 3 are both fixedly connected with a screw rod 5, and the lower surface of the connecting seat 4 and the bottom end of the guide rod 3 are both provided with a thread groove 6 for screwing in the screw rod 5.
[0025] The measuring needle 2 can be fixed to the bottom of the guide rod 3 by screwing the screw 5 into the threaded groove 6, and the two guide rods 3 can be spliced together. The screw 5 at the top of the guide rod 3 is screwed into the threaded groove 6 on the lower surface of the connecting seat 4, so that the guide rod 3 and the hand box 1 can be fixedly connected.
[0026] like Figure 1-Figure 2 As shown, a handle 10 is fixedly connected to the upper surface of the hand box 1. It is convenient to move the hand box 1 by holding the handle 10.
[0027] like Figure 2 and Figure 4As shown, the winding assembly 11 includes a horizontal axis 111 rotatably connected to the inner wall of the hand box 1, and two wire wheels 112 are fixed to the surfaces of both ends of the horizontal axis 111. Reserved holes 12 are opened on the bottom wall of the hand box 1 and below the two wire wheels 112. The top ends of the two steel wires 9 pass through the reserved holes 12 and are respectively wound on the surfaces of the two wire wheels 112.
[0028] When the two wire wheels 112 rotate forward or reverse at the same time, the wire wheels 112 can reel in or unreel the steel wire 9, thereby pulling the test cake 7 up or down through the steel wire 9.
[0029] like Figure 2 and Figure 4 As shown, a driven bevel gear 113 is fixed to the middle of the horizontal axis 111, and the winding assembly 11 also includes a driven shaft 114 and a driving shaft 117 that penetrate the side wall of the hand box 1 and are rotatably connected to the side wall of the hand box 1. A driving bevel gear 115 and a pinion 116 are fixed to the end of the driven shaft 114 located in the hand box 1, and the driving bevel gear 115 is meshed with the driven bevel gear 113.

[0032] Working principle: According to the depth of the pile hole, a corresponding number of guide rods 3 are spliced between the top of the measuring needle 2 and the connecting seat 4. During the splicing process, the measuring cake 7 is placed on the surface of the guide rod 3. Then, the handle 10 is held to vertically extend the guide rod 3 and the measuring needle 2 into the pile hole, and the measuring needle 2 is inserted into the sediment until the bottom of the measuring needle 2 contacts the bottom of the pile hole. Then, the hand wheel 119 is turned to unwind the steel wire 9, so that the measuring cake 7 descends along the guide rod 3 into the pile hole until the measuring cake 7 contacts the upper surface of the sediment. At this time, the steel wire 9 is kept straight and the locking bolt 1110 is tightened. Then, the guide rod 3, the measuring needle 2 and the measuring cake 7 are lifted up from the pile hole. Finally, the distance from the bottom of the measuring needle 2 to the lower surface of the measuring cake 7 is measured, which is the sediment thickness.
