[0002] Channel reconstruction or channel information construction all need to measure accurate channel coordinates and height data, and the channel bottom height is usually obtained by RTK, total station prism or leveling method, the RTK and total station measurement method is fast, but the precision of channel bottom height measurement is poor. For important channel buildings or channel measurement projects with small channel gradient, the channel bottom height requires high measurement precision, and only the leveling method can be used in the prior art. After the channel runs, the bottom will be silted to different degrees (mixture of soil, sand and water), and some siltation even reaches 0.3-0.5m in depth. When leveling, a foot pad is placed on the channel bottom, a leveling rod is placed on the foot pad, the height of the channel bottom is obtained by subtracting the height of the foot pad after measuring the height of the top of the foot pad. The existing foot pad is a solid cast iron weight foot pad with low height and small size, which is mainly used for leveling of hardened pavement, and almost cannot achieve the effect for silted channel bottom, and even cannot be used.

[0024] The present application will be described in detail below in combination with embodiments, but the present application is not limited to these embodiments.

[0025] The present application embodiment provides an elevation measurement auxiliary device, as shown in Figs. 1 to 3 The device comprises:

[0026] sleeve 1;

[0027] A plurality of support rods 2 are inclinedly distributed around the side wall of the sleeve 1; one end of each support rod 2 is fixed on the side wall of the sleeve 1, and the other end is in contact with the ground; the plurality of support rods 2 are used to support the sleeve 1 to be vertically suspended;

[0028] Supporting rod 3 is arranged in sleeve 1; bottom end of supporting rod 3 is in contact with the elevation surface to be measured, and top end of supporting rod 3 is used for placing a leveling staff; sleeve 1 is used for limiting supporting rod 3 in the vertical direction.

[0029] Wherein, the bottom end of the supporting rod 3 is a pointed end, facilitating contact with the concrete bottom plate of the channel bottom.

[0030] The top end of the supporting rod 3 is in contact with the leveling staff point surface. In actual application, the top end of the supporting rod 3 can be provided in a hemispherical shape.

[0031] In the embodiment of the utility model, the diameter of the supporting rod 3 is slightly smaller than the size of the sleeve 1, and the purpose is to prevent the supporting rod 3 from shaking too much in the sleeve 1.
