Concrete face level measurement device under water
Technical field
The utility model relates to a kind of face of concrete under water level measurement device.
Background technology
In the concrete pouring construction, owing to lack special-purpose survey instrument, the workmen can't accurately measure concrete face absolute altitude under water, and causes concrete to surpass designed elevation or do not reach problem such as designed elevation occurring, and has a strong impact on construction quality, increases construction cost.
Summary of the invention
The purpose of the utility model is to provide a kind of face of concrete under water level measurement device, and it can accurately be measured the concrete height in the pouring construction, guarantees that the precise control of concrete absolute altitude puts in place.
The purpose of the utility model realizes through following technical scheme: a kind of face of concrete under water level measurement device is characterized in that: the measuring ropes that it comprises plummet, is fixed in the guard of plummet upper end and is fixed in the plummet upper end.
The method of application of the utility model is following: during measurement; Slowly transferring measuring ropes descends plummet slowly; After running into concrete, plummet submerges in the concrete, and guard can't sink because of the suspension resistance that receives coarse aggregate; Make the plummet upper surface rest on the concrete surface, then read the length reading of measuring ropes and just can know concrete face position.
The utility model has also carried out following improvement:
Said plummet lower end is fixedly connected with gets aggregate bucket; In the time of can after measurement, mentioning plummet like this, take out a small amount of coarse aggregate, have in the accurate entering concrete with the proof plummet; Prevent plummet because of in the concrete that accurately do not submerged by reasons such as other objects tangle, and cause measurement data inaccurate.
Compared to prior art, the advantage of the utility model is: it can accurately be measured the concrete height in the pouring construction, guarantees that the precise control of concrete absolute altitude puts in place, makes construction quality be effectively controlled, and reduces construction cost.

Embodiment
Below in conjunction with Figure of description and embodiment the utility model content is elaborated:
Embodiment synoptic diagram like Fig. 1, Fig. 2 and a kind of face of the concrete under water level measurement device that provides for the utility model shown in Figure 3.
A kind of face of concrete under water level measurement device is characterized in that: the measuring ropes 3 that it comprises plummet 1, is fixed in the guard 2 of plummet 1 upper end and is fixed in plummet 1 upper end.
Said plummet 1 lower end is fixedly connected with gets aggregate bucket 4.
The said aggregate bucket 4 of getting is the string bag.
Said guard 2 is a semisphere, is fixedly arranged on the plummet 1 through nut-screw assembly 5.
