[0029] Reference Figure 1 As shown, the utility model provides a technical solution: a benchmark for engineering measurement, including a first benchmark 1 and a second benchmark 2, the first benchmark 1 and the second benchmark 2 are threadedly connected, a cone head 3 is fixedly installed on the end side of the first benchmark 1, a supporting device 4 is provided on the side wall of the first benchmark 1, and a limiting device 5 is provided on the side wall of the first benchmark 1.
[0030] The specific arrangement and function of the supporting device 4 and the limiting device 5 will be described in detail below.
[0031] Reference Figure 1-Figure 4As shown, in this embodiment: the support device 4 includes an external thread 45 provided on the side wall of the first mark rod 1, the side wall of the external thread 45 is threadedly connected with a screw ring 44, and the side wall of the screw ring 44 is evenly fixedly connected with six limit blocks 48 in groups of two, and the six limit blocks 48 are in groups of two, and the side of two limit blocks 48 close to each other is rotatably connected with a support bar 41. After the cone head 3 on the first mark rod 1 is inserted into the ground, the screw ring 44 on the side wall of the external thread 45 can be rotated to make the connecting tube 46 on the support bar 41 against the ground, which can increase the support area of the first mark rod 1 when it is erected on the ground, thereby improving the stability of the use of the first mark rod 1. The side wall of the support bar 41 is provided with a reserved hole 49, and the inner side of the reserved holes 49 on the three support bars 41 is penetrated with an elastic ring 47. The support bar 41 will be expanded by the contraction force of the elastic ring 47.
[0032] The other end of the support bar 41 is fixedly connected to a connecting tube 46, and a limiting rope 42 is passed through the inner side of the three connecting tubes 46. By contracting the limiting rope 42 to bind the three support bars 41 to the side wall of the first pole 1, the support bar 41 can be retracted. Both ends of the limiting rope 42 are fixedly connected to a ball 43. By providing the ball 43, the limiting rope 42 can be prevented from slipping off the inner side of the connecting tube 46 during the contraction of the limiting rope 42.
[0033] Reference Figure 1-Figure 3 and Figure 5 As shown, specifically, the limiting device 5 includes a limiting strip 51 fixedly connected to the side wall of the first marking pole 1, and the limiting strip 51 is a "U"-shaped structure. The excess limiting rope 42 is wound around the inner side of the limiting strip 51, and the limiting strip 51 with a "U"-shaped structure facilitates the limiting work of the limiting rope 42 after contraction.
[0034] The end side of the limit bar 51 is rotatably connected with a rotating pin 52, and the inside of the rotating pin 52 is slidably connected with a sliding rod 53, and the other end of the sliding rod 53 is fixedly connected with a baffle 54, and the surface of the baffle 54 is fixedly connected with three cone rods 55. The cone rod 55 is inserted into the inside of the winding rear limit rope 42 to achieve the fixing work of the winding rear limit rope 42. The surface of the sliding rod 53 is covered with a spring 56, and the two ends of the spring 56 are fixedly connected to the rotating pin 52 and the baffle 54 respectively. The baffle 54 will be driven by the tension of the spring 56 to drive the cone rod 55 to be tightly inserted into the inside of the limit rope 42, thereby improving the stability of fixing the limit rope 42.
[0035] Working principle: when the engineering surveying benchmark is used on a loose engineering ground, the three support bars 41 are unfolded, and the support bars 41 are unfolded by the contraction force of the elastic ring 47. At this time, after the cone head 3 on the first benchmark 1 is inserted into the ground, the screw ring 44 on the side wall of the external thread 45 can be rotated to make the connecting tube 46 on the support bar 41 press against the ground, which can increase the supporting area of the first benchmark 1 when it is erected on the ground, thereby improving the stability of the use of the first benchmark 1. By setting the screw ring 44 and the first benchmark 1 as a threaded connection structure, the support height of the support bar 41 can be adjusted, which is convenient for inserting the cone head 3 into different depths according to the softness of the ground, and the support bar 41 presses against the ground for support. After using the structure, The three support bars 41 can be retracted by contracting the limit rope 42 to bind the side wall of the first benchmark 1, so that the support bar 41 can be folded up, and after the support bar 41 is folded up, the support bar 41 can cover the cone head 3, so as to avoid the cone head 3 directly stabbing the staff in the later process of carrying the first benchmark 1, thereby improving the safety performance of the use of the first benchmark 1. By setting the sphere 43, it can be avoided that the limit rope 42 slips off the inner side of the connecting tube 46 during the contraction of the limit rope 42. By setting the supporting device 4, it is convenient to further stabilize the support work of the first benchmark 1 on soft engineering ground, improve the stability of the first benchmark 1 inserted into the soft ground, and further improve the performance of the engineering measurement benchmark.
[0036] When it is necessary to retract the limit rope 42, first rotate the rotating pin 52 to rotate the cone rod 55 to a position staggered with the inner side of the limit strip 51. At this time, the excess limit rope 42 can be wrapped around the inner side of the limit strip 51. The limit strip 51 with a "U"-shaped structure facilitates the limiting work of the limit rope 42 after retraction. After the support strip 41 is tightened on the first benchmark 1, the slide bar 53 can be slid to lift the baffle 54. After the baffle 54 is lifted to a certain height, the rotating pin 52 is rotated to rotate the cone rod 55 to face the inner side of the limit strip 51. The baffle plate 54 is in the position, and the conical rod 55 is inserted into the interior of the wound rear limiting rope 42 at this time, so that the wound rear limiting rope 42 can be fixed. The baffle plate 54 will be driven by the pulling force of the spring 56 to drive the conical rod 55 to be tightly inserted into the interior of the limiting rope 42, thereby improving the stability of fixing the limiting rope 42. By setting the limiting device 5, the fixing of the rear limiting rope 42 is facilitated, and the rear support bar 41 is avoided from spreading out after being folded, thereby further improving the stability of the restraint of the rear support bar 41.
