Description :
Customized observation mark protection box for Chaozhou observation point processing factory
The product varieties include: cross measuring nails, settlement deformation observation markers, cross GPS point markers, leveling point markers, cross control point markers, elevation point markers, settlement point observation markers, mandatory settlement observation point protection boxes, pier body observation markers, settlement observation piles, boundary points, embedded split type observation markers, identification signs and other measurement markers. They can also be customized according to the drawings (engraved with the unit name, project name, point number, pier body number and other text content for future use and management, as well as the brand image promotion of the unit). The product is widely used in settlement observation, deformation monitoring, leveling measurement, elevation measurement, control measurement, displacement measurement, cadastral measurement, etc.
（1） Calibration of observation points
1. Arrangement of observation points
The observation points should be arranged in the following positions:
(1) The boundary between deep-seated rock mass and surrounding rock;
(2) The boundary between various units or intrusive bodies within the pluton;
(3) The boundary between different facies zones in the pluton;
(4) On the alteration zone and contact metamorphic zone in the pluton;
(5) The internal structure of the rock mass, the location where xenoliths (inclusions), joints, and phenocrysts are developed;
(6) A location with good rock outcrops, obvious characteristics, and representativeness for key observation and sampling of lithology;
(7) The location of faults, mineral deposits, or mineralization points.
2. Density of observation points
Depends on the accuracy requirements of geological survey. In 1:50000 geological mapping, the point spacing in the exposed area of bedrock is generally 300-500m. If there is poor outcrop or little change in lithology, the point spacing can be appropriately relaxed to 800-1000m.
The density of observation points is a product of the combination of the accuracy of geological surveys and the actual geological conditions within the work area, but accuracy requirements are dominant.
3. Calibration method for observation points
Each observation route (point) should be numbered consecutively, marked on the topographic map, and recorded in detail in the field logbook. The calibration method for observation points is the same as that for sedimentary rock areas, as described in this chapter.
