[0002] The surveying bench mark is the fixed point for transmitting elevation in leveling survey, and is important infrastructure in engineering surveying and topographic mapping. The layout of the surveying bench mark needs to consider topography, geology, climate and other factors to ensure its stability and accuracy. Especially in the plateau permafrost region, the influence of frost heaving and freeze-thaw on the stability of the surveying bench mark needs to be paid special attention. Permafrost refers to various rocks and soils containing ice, which is widely distributed in plateau regions. Due to the thermal expansion and contraction characteristics of permafrost, the ground surface will deform significantly during frost heaving and freeze-thaw.

Maintenance personnel can easily reach the surveying bench mark location to clean, check and other work.
[0004] The existing surveying bench mark is generally drilled by drill rod before pouring concrete into the hole. During use and observation, it is found that the contact area between the foundation of the surveying bench mark formed by this drilling method and the soil is insufficient, which may lead to insufficient bearing capacity and anti-pulling capacity of the control point.

[0025] The specific embodiments are given below.
[0026] Please refer to Figures 1 to 6As shown, the utility model discloses a kind of measuring control point ground hole enlarging device, including support 1, the top of support 1 is fixedly connected with first hydraulic cylinder 12;The output end of first hydraulic cylinder 12 is fixedly connected with top plate 13;Second telescopic rod 115 is fixedly connected between top plate 13 and support 1;First hydraulic cylinder 12 and second telescopic rod 115 are symmetrically arranged;The top of top plate 13 is fixedly connected with motor 14;The output end of motor 14 is fixedly connected with equipment box 15;Top plate 13 is between motor 14 and equipment box 15;The bottom of equipment box 15 is fixedly connected with drill rod 16;Equipment box 15 and drill rod 16 are in communication relationship;The inner wall of drill rod 16 is fixedly connected with vertical rod 19, and vertical rod 19 top extends to the top of equipment box 15 inner side wall;The bottom of equipment box 15 inner side wall is fixedly connected with second hydraulic cylinder 17;The output end of second hydraulic cylinder 17 is fixedly connected with connecting plate 18;Connecting plate 18 and vertical rod 19 are slidingly fitted;The bottom of connecting plate 18 is fixedly connected with round plate 110;Round plate 110 and vertical rod 19 are slidingly fitted;Multiple connecting rods 111 are rotatably connected to the bottom of round plate 110;The end of connecting rod 111 is rotatably connected with sliding plate 112;First telescopic rod 114 is fixedly connected between sliding plate 112 and drill rod 16 inner wall;Adjacent first telescopic rod 114 is staggered arrangement;The outside of sliding plate 112 is rotatably connected with tooth ball 113;The surface of tooth ball 113 is provided with multiple spines;Sliding plate 112 and drill rod 16 outer wall are fixedly connected with elastic cloth 116;The inside of equipment box 15 is provided with slag removal assembly;When working, the device can be moved to the target site, and when drilling is needed, the first hydraulic cylinder 12 and the motor 14 can be started respectively.
