Description

Technical Field

[0001] The utility model relates to the field of a feeler rod, in particular to a feeler rod marked with scales. Background Art

[0002] Probing is a field experimental method for measuring the density and strength of soft soil. There is a static probing method for probing. When conducting static probing, a probing device is used, and the probing device is generally a conical probe with certain specifications. During the test, the probe is connected to the probing rod. As the test depth increases, the staff needs to continuously lengthen the probing rod. Traditional probing rods are connected to other probing rods by snapping or screwing, thereby extending the length of the entire probing rod. When two probing rods are connected by screwing, generally a screw is set at the end of one of the probing rods, and a screw hole matching the screw is set at the end of the other probing rod. When the screw is rotated a corresponding number of times along the number of threads, the connection between the two probing rods can be completed. In order to ensure the stability of the two probing rods when connected, generally more threads are set, so it is necessary to rotate many times to complete the connection, which not only increases the workload of the staff, but also wastes time, and the connection efficiency is extremely poor, resulting in the process of lengthening the length of the probing rod seriously affecting the normal progress of the probing work and reducing the probing efficiency.

The quick-connectable feeler rod of the utility model can complete the screw connection between the screw and the screw hole by rotating a very small number of times when there are a lot of thread turns, and can quickly connect the various rods to achieve the effect of quickly adjusting the length.

[0027] There are several limit grooves 4, and several limit grooves 4 are evenly distributed on the front side of the No. 1 rod body 1; by setting the limit grooves 4, when conducting a geological sounding test, the No. 2 rod body 2 is inserted into the ground. At this time, the limit grooves 4 and the scale grooves 3 can mark the insertion depth of the No. 2 rod body 2, so as to avoid the problem that the surface of the No. 2 rod body 2 is relatively smooth, making it difficult for the staff to control the injection depth of the No. 2 rod body 2, resulting in a large error in the injection depth, thereby causing a large error in the geological sounding test results, thereby improving the accuracy of the geological sounding test results.

[0028] The material of the marking sleeve 5 is red copper material, and the marking sleeve 5 is adapted to the limit groove 4; by setting the marking sleeve 5, when the probe rod is inserted, sand and gravel can rub against the surface of the marking sleeve 5, and at this time the marking sleeve 5 can mark the position of the scale groove 3, thereby avoiding the problem that the scale groove 3 is severely worn due to long-term friction with sand and gravel, and then causing the scale groove 3 to disappear, thereby improving the stability of the scale groove 3 during operation, that is, improving the service life of the probe rod.

[0035] The working principle of the probe rod with scale provided by the utility model is as follows:

[0036] Step 1: First, when conducting a geological sounding test, the No. 2 rod body 2 is inserted into the ground. At this time, the limit groove 4 and the scale groove 3 can mark the insertion depth of the No. 2 rod body 2, so as to avoid the problem that the surface of the No. 2 rod body 2 is relatively smooth, which makes it difficult for the staff to control the injection depth of the No. 2 rod body 2, resulting in a large error in the injection depth, thereby causing a large error in the geological sounding test results, thereby improving the accuracy of the geological sounding test results. When the sounding rod is inserted and injected, sand and gravel can rub against the surface of the marking sleeve 5. At this time, the marking sleeve 5 can mark the position of the scale groove 3, so as to avoid the scale groove 3 being severely worn by the sand and gravel for a long time, thereby causing the scale groove 3 to be The problem of the disappearance of the scale groove 3 is solved, thereby improving the stability of the scale groove 3 when working, that is, improving the service life of the sounding rod. When conducting a geological sounding test, the fixing block 61 is sleeved inside the detection host, and the threaded rod 62 is rotated at this time, so that the threaded rod 62 can fix the fixing block 61 inside the detection host, thereby achieving the fixing effect of the No. 1 rod body 1 and the detection host, and thus facilitating the installation and fixation of the sounding rod. When adjusting the length of the sounding rod, the tapered column 72 is threadedly sleeved inside the positioning groove 71, so that the No. 1 rod body 1 and the No. 2 rod body 2 can be fixedly connected, thereby achieving the adjustment effect of the length of the No. 1 rod body 1, and thus facilitating the adjustment of the length of the sounding rod;

[0037] Step 2: When the No. 1 rod body 1 and the No. 2 rod body 2 are fixedly connected, the sealing sleeve 8 can fill the gap between the No. 1 rod body 1 and the No. 2 rod body 2, so as to avoid the problem that the mud and sand enter the No. 2 rod body 2 through the gap when the probe rod is inserted and poured, causing the internal pollution of the probe rod, thereby improving the protection effect of the inside of the probe rod; when the No. 1 rod body 1 and the No. 2 rod body 2 are rotationally connected, the anti-skid column 9 is manually rotated so that the anti-skid column 9 can be threadedly sleeved on the bottom of the No. 1 rod body 1, so as to avoid the problem that the No. 2 rod body 2 slides when the No. 2 rod body 2 is manually rotated due to the relatively smooth surface of the No. 2 rod body 2, thereby improving The stability of the No. 2 rod body 2 during manual rotation is improved. When the probe rod is inserted into the ground for a long time and is severely worn, the crushing column 11 is rotated so that the crushing column 11 can drive the threaded column 10 to fall off from the bottom of the No. 2 rod body 2, thereby achieving the disassembly effect of the crushing column 11, thereby facilitating the replacement of the crushing column 11. When the probe rod is inserted and poured, the drill bit 12 can crush the stones inside the soil, thereby avoiding the problem of serious wear of the No. 2 rod body 2 caused by the stones squeezing and rubbing the bottom of the No. 2 rod body 2, thereby achieving the protection effect of the No. 2 rod body 2, that is, the protection effect when the probe rod is working.
