Abstract
A combination checking and measuring water column which is composed of four same transparent checking and measuring water columns which are connected with soft tubes. Every checking and measuring water column has a vertical type hollow transparent round tube with a chassis, and the upper end has an opening and an exhaust cap (5). A tube wall is craved with vertical graduations with millimeter as a unit, and the lower of the tube wall has two interface branch tubes (2) which are connected with the branch tubes of the interfaces of other checking and measuring water columns with the soft tubes (3) and are communicated. Water is arranged in the checking and measuring water column, and a color sign (4) is arranged in the vertical type tube and floats on the water surface. The sizes of the chassis of each of the transparent checking and measuring water column and the connection part of the vertical type tube are gradually reduced, and the sizes of the middle and the upper parts of the vertical type tube are the same. The utility model has the prominent advantages that the checking and the measurement of a large size plane is very quick and accurate.
Description
Planar combination school survey water column is surveyed in a kind of school that is used for, and belongs to the school and surveys technical field of tools.
Present surveyor's staff and measuring instrument are subjected to the school to survey the influence that face out-of-flatness and barrier stop sight line, use very inconveniently, and accuracy is not high.
The purpose of this utility model provides a kind of school of making up and surveys water column to improve the precision and the speed of school lining face.
The technical solution of the utility model is, it is surveyed water column by four identical transparent schools and connects to form with flexible pipe, it is the vertical hollow transparent garden pipe that the chassis is arranged that water column is surveyed in each school, there are opening, exhaust cap (5) in the upper end, tube wall (1) is that unit is carved with scale with the millimeter, two interface arms (2) are arranged at the tube wall bottom, survey water column interface arm with flexible pipe (3) and other school and couple together, and are communicated with each other.The school is surveyed in the water column water is housed.There is a colour code (4) to float on the surface in the vertical tube.
The chassis of each transparent school survey water column is connected the part size with vertical tube be to reduce gradually, and vertical tube middle and upper part part size is identical.
Fig. 1 the utility model front view
Fig. 2 is Fig. 1 vertical view
During use water columns are surveyed in 4 transparent schools of the present utility model and be placed on the scale of then being surveyed water column colour code indication on 4 points in smoothing face front, rear, left and right, just can determine by smoothing face level whether according to each school.If level, then the scale of 4 school survey water column colour code indications is the same.If indicating graduation is different, then indicate on the low side that to be higher than level, indicate that higher then that is lower than level.So just can take measures quickly and easily being smoothed the good level in face school.Especially the school on large scale plane is surveyed accurately quick especially.
Claims (2)
1, water column is surveyed in lining face usefulness combination school, a kind of school, it is characterized in that surveying water column by four identical transparent schools, connect to form with flexible pipe, it is the vertical hollow transparent garden pipe that the chassis is arranged that water column is surveyed in each school, and there is opening exhaust cap (5) upper end, tube wall (1) is that unit is carved with vertical scale with the millimeter, two interface arms (2) are arranged at the tube wall bottom, survey water column interface arm with flexible pipe (3) and other school and couple together, and are communicated with each other, the school is surveyed in the water column water is housed, and has a colour code (4) to float on the surface in the vertical tube.
2, water column is surveyed in combination according to claim 1 school, it is characterized in that each transparent school surveys the chassis of water column and be connected the part size with vertical tube and reduce gradually, and vertical tube middle and upper part part size is identical.
