Detailed Description

The present invention will be further described with reference to the accompanying drawings and embodiments.

Referring to fig. 1-5, in an embodiment of the present invention, a level for engineering survey includes: the leveling instrument comprises a triangular support 1, a mounting disc 2 and a leveling instrument body 3, wherein the triangular support 1 is rotatably mounted at the bottom of the mounting disc 2, and the leveling instrument body 3 is fixedly mounted at the top of the mounting disc 2; the annular groove 4 is formed in the outer side of the mounting disc 2; the two arc structures are arranged on the outer ring of the mounting plate 2 and comprise arc plates 6 and arc blocks 5, the arc blocks 5 are fixedly arranged on the inner sides of the arc plates 6, the arc blocks 5 are matched with the annular grooves 4, and the arc plates 6 are arranged on the outer sides of the mounting plate 2; and the water blocking shed 11 is arranged right above the level gauge body 3.

The arc-shaped plate 6 and the arc-shaped block 5 are both of semicircular structures, and the circle centers are the same.

Two fixed plates 7 are symmetrically arranged at two ends of the arc-shaped plate 6, and threaded through holes are formed in the fixed plates 7.

Four two lead screws 8 are installed on the fixed plate 7 in a threaded mode, and handles 9 are fixedly installed at one ends of the two lead screws 8.

Two equal fixed mounting in top of arc 6 has the bracing piece 10, and two bracing pieces 10 are the symmetric distribution.
