Verification is the soul of surveying.
The verification is divided into: calculation data should be released for inspection (calculation verification, data verification, instrument verification, lofting verification, acceptance verification).
Leveling instruments: standards (rulers, levels).
Triangular elevation measuring instruments: latitude and longitude full ranging (theodolite, total station, (laser) rangefinder).
Barometric elevation measuring instrument: (mercury, empty box) barometer.
Principle of baseline measurement: use of steel bars (verification steel ruler, theodolite).
Pipeline main point: the starting point, end point, and turning point.
Underground pipeline measurement: before backfilling, measure the starting and ending points, the coordinates of the manhole, and the elevation of the top of the pipe (the coordinates of the top height and the end well).
The level consists of: base, level (or compensator), telescope (base horizontal telescope).
Theodolite composition: base, degree plate (horizontal and vertical dial), alignment part (base dial alignment part).
The function of the level: measuring the elevation, elevation and settlement.
The function of theodolite: measure horizontal angle, vertical angle, vertical and horizontal center line.
The function of the total station: to measure the horizontal angle of the distance coordinates (distance (slant distance, flat distance, height difference), horizontal distance measurement, coordinate measurement, horizontal angle measurement).
Large-diameter, long-distance, transformable equipment, concentricity measurement: laser collimator and laser pointing instrument (heart straight, large long straight).
Small lifting equipment: jack hoist slide (jack, winch, hoist, pulley).
Unconventional cranes: hydraulic mast lift gates (hydraulic lifting systems, mast cranes, construction hoists, gantry cranes).
The basic parameters of the crane selection: high load lifting capacity (maximum lifting height, maximum amplitude, lifting load, rated lifting capacity).
The main reasons for the instability of lifting machinery: mechanical failure, unstable legs, overrun and overload of elevation angle (mechanical failure, instability of outriggers, overrun and overload of lifting boom elevation angle).
Wire rope safety factor:
Drag 35;winch tie-up 5; Manned 14**6
Tow rope 35;Hoist rope 5;Tie lanyard clasp 5;Manned gondola 14;**Rope buckle 6
Rope winding of the pulley group: 37 shun double 46 flowers.
3 doors and below are worn smoothly, 4-6 doors are worn by flowers, and 7 doors and above are worn by double running heads).
The basic parameters of the winch: pulling speed and rope capacity (rated traction tension, working speed, rope capacity).
Critical engineering: Critical is very more than 1 ton (unconventional, and more than 10kn).
The general contractor of the construction (if subcontracted is the relevant professional subcontractor), the special construction plan shall be prepared, and the two general contractors (the technical person in charge of the general contractor and the chief engineer) + two chapters (the official seal of the unit and the practice seal).
Over-hazard engineering: over-hazard is very more than 10 tons (100kn), weighs 300 (kn) and is 200 (m) high
Two general + two chapters + expert argumentation.
