Description

Technical Field

[0001] The present invention relates to the field of underground building construction, in particular to a device for detecting the thickness of sediment during underground hole digging, piling and wall construction. Background Art

[0002] Sediment refers to the sediment left behind during the drilling and cleaning process, or after a hole collapse, that is not carried away by the circulating slurry. It is generally composed of coarse particles. Sediment thickness refers to the height of this layer. Typically, construction sites use two measuring ropes to suspend an object, measuring the depth to the bottom of the hole and the depth to the sediment surface. While this method is simple, it is slow and cumbersome. With the advancement of technology, electronic technology has been incorporated into measurement methods to improve them.

[0003] Prior art CN221612038U discloses a sediment thickness detection device, which consists of a winding assembly and a detection assembly. The detection assembly is composed of an insertion rod, a pressure sensor, a laser rangefinder, and a target plate. The pressure sensor at the bottom of the insertion rod touches the bottom, which activates the laser rangefinder to shoot the distance to the target plate, thereby realizing the sinking of the detection needle. However, according to the working conditions at the construction site, this measurement environment is in a water layer, and the sediment layer is a mixture of mud and water. Therefore, when the pressure sensor and laser rangefinder of this device are used in this environment, there is a certain environmental interference on the sensitivity of the measurement and the accuracy of the measurement data. At the same time, high-precision electronic sensors and electronic measuring instruments are easily damaged in such an environment. Therefore, the calibration, maintenance, and replacement of instruments and equipment are all problematic.

[0004] In view of this, the present invention proposes a device for detecting sediment thickness in combination with actual construction conditions to solve the above-mentioned problems. Summary of the Invention

[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a simple, fast, easy to construct and reusable sediment thickness detection device and method, which is used to improve the sediment thickness detection efficiency, solve the problems of long detection time, complex operation and environmental interference, and improve the detection efficiency and the quality of detection data results.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A device for detecting sediment thickness includes a lifting rope, a lifting hook, an anti-fall safety rope, a measuring rod, a measuring disk and a snap clamp. The measuring rod is inserted into the measuring disk and passes through the snap clamp. The lifting rope lifts the measuring rod, the measuring disk and the snap clamp through the lifting hook. The anti-fall safety rope connects the lifting hook and the measuring disk.

[0008] Furthermore, a lifting ring disk is provided on the upper part of the measuring rod, the rod body is a toothed column, and a conical head is provided on the bottom.

[0009] Furthermore, a snap-fitting groove and a guide casing limiter are provided at the center of the chassis of the measuring disk, and drag-reducing holes are provided around the periphery.

[0010] Furthermore, the guide limiting casing is a hollow circular tube with a diameter larger than the tooth column, and a safety ring is provided on the guide limiting casing.

[0011] Furthermore, the snap clip is composed of a spring, a Z-shaped clip and a rotating shaft. The snap clip is installed in the snap clip groove. The spring is respectively connected to the chassis and the Z-shaped clip. The Z-shaped clip rotates around the rotating shaft in the snap clip groove.

[0012] Furthermore, the edge tooth profile of the Z-shaped clamp matches the tooth profile of the clamping tooth column.

[0013] A sediment thickness detection device for measuring sediment comprises the following steps:

[0014] Step 1: Pass the lifting rope through the hook and hook the lifting ring on the measuring rod with the hook, so that the measuring rod is hoisted into the guide sleeve limit of the measuring disc, and the tapered head of the measuring rod extends a certain distance from the bottom of the chassis, and measure the initial value with a ruler;

[0015] Step 2: Pass the anti-fall safety rope through the safety rings on the hook and measuring plate respectively;.

[0016] Step 3: Lift the rope, the measuring plate and the clip are caught by the sliding teeth on the measuring rod, and are suspended along with the measuring rod and lowered to the point to be measured;

[0017] Step 4: When the measuring disc touches the muddy water surface, the measuring disc stops suspended by buoyancy, and the measuring rod is pulled downward by its own weight, causing the Z-shaped clamp to open. When the measuring rod slides downward by one tooth distance, the spring pulls the Z-shaped clamp back to the horizontal position and clamps it. This cycle repeats, and the tightness of the rope is used to determine whether the conical head of the measuring rod has penetrated the sediment layer and touched the bottom of the hole.

[0018] Step 5: When the conical head reaches the bottom of the hole, lift the rope. The measuring disc is clamped by the buckle and lifted upward while maintaining its position relationship with the measuring rod. The muddy water in the hole passes through the drag-reducing holes on the measuring disc, reducing the resistance when the measuring disc is pulled upward.

[0019] Step 6: Continue to lift the rope upwards until the device is completely lifted out of the ground. Use a ruler to measure the reading between the tip of the cone head and the bottom plate of the measuring plate. Subtract the initial value measured previously to get the initial sediment thickness.

[0020] The beneficial effects of the present invention are:

[0021] When the present invention is in use, the device is suspended and lowered to the sediment surface by a lifting rope. The measuring disk is suspended by buoyancy, and the measuring rod slides downward tooth by tooth under gravity until it passes through the sediment layer and reaches the bottom of the hole. At this time, the lifting rope is pulled upward, and the teeth on the measuring rod column are locked with the snap clamp. Continue to pull upward, and the end of the snap clamp presses against the guide casing to limit the position, and is lifted to the ground together with the measuring rod. The distance between the tip of the conical head and the bottom of the measuring disk is measured by a tape measure to calculate the sediment thickness.

[0022] The device of the present invention replaces the traditional manual method of inserting the measuring needle and the measuring disk twice to read the scale on the measuring rope. The operation is simpler and more efficient, and the data is more accurate.

[0023] The device of the present invention is assembled from common parts used on construction sites, has a simple structure, is easy to manufacture and process, has a low cost, can maintain a good use state in muddy and water environments, and has strong applicability.

DETAILED DESCRIPTION

[0029] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.

[0030] like Figures 1 to 4 As shown, a device for detecting sediment thickness of the present invention includes a lifting rope 1, a lifting hook 2, an anti-falling safety rope 3, a measuring rod 4, a measuring rod 5 and a snap clamp 6.

[0031] The measuring rod 4 is inserted into the measuring disk 5 and passes through the snap clamp 6. The lifting rope 1 lifts the measuring rod 4, the measuring disk 5 and the snap clamp 6 through the hook 2. The anti-fall safety rope 3 connects the hook 2 and the measuring disk 5.

[0032] like Figure 2 As shown, the upper portion of the measuring rod 4 is provided with a hanging ring plate 401, the rod body is a toothed column 402, and the bottom is provided with a conical head 403.

[0033] like Figure 3 As shown, the center of the chassis 501 of the measuring disk 5 is provided with a snap-fitting groove 504 and a guide sleeve limiter 502, and the periphery is provided with a drag reduction hole 505. The guide sleeve limiter 502 is a hollow circular tube with a diameter slightly larger than the tooth column 402, and a safety ring 503 is provided on the guide sleeve limiter 502.

[0034] like Figure 4 As shown, the snap clip 6 comprises a spring 601, a Z-shaped clip 602, and a rotating shaft 603. The snap clip 6 is mounted within the snap clip slot 504. The spring 601 connects the chassis 501 and the Z-shaped clip 602, respectively. The Z-shaped clip 602 rotates within the snap clip slot 504 around the rotating shaft 603. The edge teeth of the Z-shaped clip 602 match the toothed column 402.

[0035] The Z-shaped clip 602 is installed in the clip slot 504 via a rotating shaft 603 and is integrally connected to the chassis 501. The upper and lower surfaces of the Z-shaped clip 602 are adjusted to be horizontal with the chassis 501. A spring 601 is placed between the Z-shaped clip 602 and the chassis 601, connecting the two together. This ensures that the Z-shaped clip 602 always maintains a horizontal plane with the chassis 501 under normal conditions and can return to its normal horizontal position after being subjected to force. A safety ring 503 is provided on the guide sleeve limiter 503 for suspending the anti-fall safety rope 3. The guide sleeve limiter 503 is placed on the chassis 501 and connected to the center surface of the clip slot 504 as a whole, limiting the upward rotation of the Z-shaped clip 602.

[0036] In this embodiment, the sediment measurement is performed using the above device, including the following steps:

[0037] Step 1: Pass the lifting rope 1 through the hook 2 and use the hook 2 to hook the lifting ring plate 401 on the measuring rod 3, so that the measuring rod 3 is hung in the guide casing limit 502 of the measuring disk 5, and the conical head 403 of the measuring rod 3 extends a certain distance from the bottom of the chassis 501, and measure the initial value with a ruler (or the size of the conical head can be customized according to the on-site conditions to facilitate calculation).

[0038] Step 2: Pass the anti-fall safety rope 3 through the safety ring 503 on the hook 2 and the measuring plate 5 respectively (the length of the anti-fall safety rope is determined according to the conditions of the construction site and only plays an anti-fall role in unexpected situations).

[0039] Step 3: Lift the sling 1, the measuring disc 5 and the snap clamp 6 are caught by the sliding teeth on the measuring rod 4, and are suspended along with the measuring rod 4 and lowered to the point to be measured.

[0040] Step 4: When the measuring disc 5 contacts the muddy water surface, the measuring disc 5 stops suspended due to the buoyancy, and the measuring rod 4 is subjected to its own gravity, causing the Z-type clamp 602 to open downward. When the measuring rod 4 slides downward by a tooth distance, the spring 601 pulls the Z-type clamp 602 back to the horizontal position and clamps it. This cycle is repeated, and the tightness of the suspension rope 1 is used to determine whether the conical head 403 of the measuring rod 4 penetrates the sediment layer and touches the bottom of the hole.

[0041] Step 5: When the conical head 403 reaches the bottom of the hole, lift the lifting rope 1, and the measuring disk 5 is lifted upward by the snap clamp 6 while maintaining the position relationship with the measuring rod 4 unchanged. The muddy water in the hole passes through the drag reduction hole 505 on the measuring disk 5, reducing the resistance when the measuring disk 5 is pulled upward.

[0042] Step 6: Continue to lift the rope 1 upward until the device is completely lifted out of the ground. Use a ruler to measure the reading between the tip of the conical head 403 and the bottom plate 501 of the measuring plate 5. Subtract the initial value measured previously to obtain the initial sediment thickness.
