Specific embodiment
The present invention is further described with reference to the accompanying drawings and detailed description.
Altitude data measurement method in basement the following steps are included: A, prepare altitude data measuring tool, such as Fig. 1 and figure
Shown in 2, altitude data measuring tool includes clamping structure 1, Top fastening screw 2 and extension rod 3, and the shape of clamping structure 1 is U-shaped,
Clamping structure 1 includes interior plate 1-1, outer panel 1-2 and top plate 1-3, and Top fastening screw 2 connect with outer panel 1-2, extension rod 3 and
Interior plate 1-1 connection is provided with the ruler hole 3-1 through extension rod 3 on extension rod 3；B, clamping structure 1 basement is buckled in reserve
The fixed clamping structure 1 of Top fastening screw 2 is tightened on hole wall 10 top in hole；C, indium steel ruler or Sopwith staff are erected and stands upright on extension rod 3 and is located at
By the 3-1 of ruler hole；The position of indium steel ruler or Sopwith staff is marked on extension rod 3, which is scale point；By level 12 by elevation
In data pilot measurement to scale point, the altitude data a of scale point is recorded；D, the ruler body 6-2 for measuring tape measure 6 is pulled out, straight down
It is extended in basement across ruler hole 3-1, then by basement preformed hole 9；E, to measure tested point using level 12 corresponding
Ruler body 6-2 reading, the corresponding ruler body 6-2 reading of tested point subtract the corresponding ruler body 6-2 of scale point and read to obtain the depth of tested point
Degree is according to b；F, it is calculated, the altitude data c=a-b of tested point.
In step C, will be specifically in altitude data pilot measurement to scale point by level 12: level elevation be it is known that water
Quasi- instrument alignment indium steel ruler or Sopwith staff any position, then the position elevation is equal to level elevation, which subtracts scale point and be somebody's turn to do
The distance of position is the elevation of scale point.The position for reducing level alignment indium steel ruler or Sopwith staff can improve number to a certain degree
According to the precision of a.
In measurement process D and E step need to the amount of holding tape measure 6, first hand-held for a long time that operator can be allowed very tired, second hand
