Preferably, two screw rods are threadedly mounted on the four fixing plates, and one end of the two screw rods is fixedly mounted with a handle.

Preferably, support rods are fixedly installed on the tops of the two arc-shaped plates, and the two support rods are symmetrically distributed.

Preferably, both of the support rods are rotatably connected to the bottom of the water retaining shed.

Preferably, a lighting lamp and a battery are installed at the bottom of the water retaining shed.

Compared with the related art, the level for engineering surveying provided by the present utility model has the following beneficial effects:

The utility model provides a level for engineering measurement. By arranging a water retaining shed, the water droplets on the roof in the tunnel can be prevented from falling on the level, and the level has a certain protective effect. Lighting is carried out in the tunnel, which facilitates the operation of the level.

Detailed ways

The present utility model will be further described below with reference to the accompanying drawings and embodiments.

1-5, in the embodiment of the present utility model, the level for engineering surveying includes: a tripod 1, a mounting plate 2 and a level body 3, the tripod 1 is rotatably mounted on the bottom of the mounting plate 2 , the level body 3 is fixedly installed on the top of the mounting plate 2; an annular groove 4 is opened on the outside of the mounting plate 2; two arc structures, two arc structures are provided On the outer ring of the mounting plate 2, the arc-shaped structure includes an arc-shaped plate 6 and an arc-shaped block 5. The arc-shaped block 5 is fixedly installed on the inner side of the arc-shaped plate 6, and the arc-shaped block 5 Matching with the annular groove 4 , the arc-shaped plate 6 is arranged on the outer side of the mounting plate 2 ;

The arc-shaped plate 6 and the arc-shaped block 5 are both semi-circular structures, and the center of the circle is the same center.

Both ends of the two arc-shaped plates 6 are symmetrically mounted with fixing plates 7 , and the four fixing plates 7 are all provided with threaded through holes.

Two screw rods 8 are threadedly mounted on the four fixing plates 7 , and one end of the two screw rods 8 is fixedly mounted with a handle 9 .

The tops of the two arc-shaped plates 6 are fixedly mounted with support rods 10 , and the two support rods 10 are symmetrically distributed.

Both of the support rods 10 are rotatably connected to the bottom of the water retaining shed 11 .

Lights 12 and batteries 13 are installed at the bottom of the water retaining shed 11 .

The working principle of the level for engineering surveying provided by the utility model is as follows:

When measuring in some tunnels with high water content, the device is first installed on the mounting plate 2, so that the water retaining shed 11 can block the water falling from the tunnel roof and prevent the water from directly dripping onto the level body 3. The leveling instrument body 3 is damaged due to the dark light in the tunnel. At this time, the lighting lamp 12 can be used to illuminate the leveling instrument body 3 to facilitate the operation of the leveling instrument body 3. When the device needs to be dismantled, turn the handle 9 to make the screw 8 Rotate, so that the lead screw 8 is moved out of the corresponding fixed plate 7, so that the two arc-shaped plates 6 can be moved, and then the two arc-shaped plates 6 are moved in the opposite direction, and the movement of the arc-shaped plate 6 drives the arc-shaped block 5 to move, Therefore, the arc block 5 is moved out of the annular groove 4, and the arc plate 6 also drives the support rod 10 to rotate at the same time.
