Description

Technical Field

[0001] The utility model relates to the technical field of sediment thickness detection, and more specifically to a device for detecting sediment thickness during construction of foundation engineering. Background Art

[0002] In the construction of foundation engineering, it is inevitable to encounter some construction projects that require underwater trenching or drilling, such as underground continuous walls and bored piles. During the construction process, the excavation and cutting of underwater soil will inevitably cause sediment to be produced in the trenches and holes. Sediment refers to the sediment that is precipitated or left behind by the collapsed hole during the drilling and cleaning process and is not carried away by the circulating mud. It is generally coarser particles. The thickness of the sediment is the height of this layer of sediment. Before pouring concrete, the sediment thickness index at the bottom of the hole stipulates that it should not be greater than 50mm for end-bearing piles and should not be greater than 100mm for friction piles. The existence of sediment at the bottom of the trench and hole will inevitably cause excessive settlement of the underground continuous wall or bored piles and reduce their bearing capacity.

[0003] At present, the detection method of sediment thickness is mostly the rope measuring method, which uses a measuring rope to measure the hole depth. However, it is difficult to observe the specific position of the sediment that the wire at the bottom of the rope contacts, which affects the detection results. Utility Model Content

[0004] The utility model aims to provide a device for detecting the thickness of sediment during construction of foundation engineering, so as to improve the accuracy of the detection result.

[0005] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0006] A device for detecting the thickness of sediment during construction of foundation engineering, comprising a base, a column fixedly connected to the base, a mounting plate fixedly connected to the top of the column, a through hole opened on the mounting plate, a plug rod slidably connected to the through hole, scale lines provided on the plug rod, a sliding seat slidably sleeved on the plug rod, an infrared ranging transmitter installed on the sliding seat, and an infrared ranging receiver installed on the bottom of the mounting plate corresponding to the infrared ranging transmitter.

[0007] Furthermore, a sliding groove is provided on the side wall of the insertion rod, a sliding block is fixedly connected to the sliding seat, and the sliding block is slidably connected in the sliding groove.

[0008] Furthermore, a limiting block is fixedly connected to the inner side wall of the through hole, and the limiting block is slidably connected to the sliding groove.

[0009] Furthermore, a socket is provided on the side wall of the plug rod, a vertical plate is provided on the mounting plate near the socket, a plug rod is slidably passed through the vertical plate, the plug rod is arranged opposite to the socket, and one end of the plug rod away from the socket is fixedly connected to a bottom plate, and a spring is connected between the bottom plate and the vertical plate.

[0010] Furthermore, a display panel is mounted on the mounting plate, and the infrared ranging transmitter and the infrared ranging receiver are both electrically connected to the display panel.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] During detection, the rod is inserted into the bottom of the hole, and the depth is measured according to the scale line as the hole bottom depth. At this time, the slide seat abuts against the sediment surface, and the depth measured by infrared ranging is taken as the sediment top surface depth. The difference between the two data is the sediment thickness, which improves the accuracy of detection. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] like Figure 1 and Figure 2 As shown, a device for detecting the thickness of sediment during construction of foundation engineering comprises a base 1, to which a column 2 is fixedly connected, to which a mounting plate 3 is fixedly connected at the top end of the column 2, a through hole is opened on the mounting plate 3, to which a plug rod 4 is slidably connected, and scale lines are arranged on the plug rod 4, a sliding seat 5 is slidably sleeved on the plug rod 4, an infrared ranging transmitter 6 is mounted on the sliding seat 5, and an infrared ranging receiver 7 is mounted at the bottom of the mounting plate 3 corresponding to the infrared ranging transmitter 6.

[0017] A slide groove 401 is provided on the side wall of the insertion rod 4, a slider 51 is fixedly connected to the slide seat 5, and the slider 51 is slidably connected in the slide groove 401; a limit block 31 is fixedly connected to the inner side wall of the through hole, and the limit block 31 is slidably connected to the slide groove 401; by setting the slide groove 401, the slider 51 and the limit block 31, the insertion rod 4 does not rotate when sliding up and down, and the slide seat 5 does not rotate when sliding, thereby ensuring that the infrared ranging transmitter 6 corresponds to the infrared ranging receiver 7.

[0018] A plug hole is provided on the side wall of the plug rod 4, and a vertical plate 8 is provided on the mounting plate 3 near the plug hole. A connecting rod 9 is slidably penetrated on the vertical plate 8, and the connecting rod 9 is arranged opposite to the plug hole. The end of the connecting rod 9 away from the plug hole is fixedly connected to a bottom plate 10, and a spring 11 is connected between the bottom plate 10 and the vertical plate 8. By providing the connecting rod 9 and the plug hole, the plug rod 4 can be limited when no detection is performed, which is convenient for overall transportation and avoids damage caused by the bottom of the plug rod 4 colliding with the ground.

[0019] A display panel 12 is mounted on the mounting plate 3 , and the infrared ranging transmitter 6 and the infrared ranging receiver 7 are both electrically connected to the display panel 12 ; the display panel 12 is used to display infrared ranging data.

[0020] Working principle:

[0021] During detection, the rod 4 is inserted into the bottom of the hole, and the depth is measured according to the scale line on the rod 4 as the hole bottom depth. At this time, the slide seat 5 abuts against the surface of the sediment, and infrared ranging is performed through the infrared ranging transmitter 6 and the infrared ranging receiver 7. The depth measured by infrared ranging is used as the depth of the top surface of the sediment. The difference between the two data is the sediment thickness, which improves the accuracy of detection.
