　　Meishan settlement observation marker manufacturer supplies settlement monitoring piles for settlement observation points

　　When conducting settlement observations of buildings, in addition to selecting appropriate settlement observation targets, it is also necessary to follow certain principles and plans in order to improve measurement accuracy and ensure smoother measurement work. Below, Xiantao Tianxiang Surveying and Mapping will take you to understand the five principles that need to be followed when observing:

　　1. Point location should be stable: Point location refers to the reference point used for observation and the settlement observation point on the observed object, both of which must be stable and sturdy to ensure that the measurement results do not deviate.

　　2. Observers need to be stable: Only fixed observers can be familiar with the entire measurement process, so as to have a comprehensive view and handle detailed issues well.

　　3. Instrument and equipment should be stable: When selecting instrument and equipment, it is advisable to choose the same model as much as possible to avoid measurement errors caused by different models of equipment.

　　4. The route method should be fixed: surveyors should select the route and formulate the plan from the beginning, and strictly follow the regulations.

　　5. The environmental conditions must be consistent: there should be no interference from other external environmental factors in order for the measured data to be accurate.

　　The above are the five principles that need to be followed in the settlement observation of buildings. Surveyors should strictly follow the above principles for observation and select settlement observation targets.

　　Object of settlement observation

　　The objects of settlement observation include: buildings with a foundation design grade of; Buildings with a design grade of Class B on composite or soft foundations; Adding floors and expanding buildings; Buildings affected by adjacent deep foundation pit excavation or changes in environmental factors such as underground water; And projects that require accumulating construction experience or conducting design back analysis; Buildings required for excellence engineering.

　　2、 Layout of settlement observation points

　　Settlement observation points should be set up at locations that can comprehensively reflect the deformation characteristics of the building foundation, generally at the four corners of the building, at corners, and every 10-15 meters along the outer wall; High and low rise buildings, new and old buildings, different geological conditions, different load distributions, different foundation types, different foundation burial depths, different upper structures, settlement joints, and both sides of building cracks; At the interior longitudinal walls of buildings with a width greater than or equal to 15 meters, or less than 15 meters but with complex geological conditions, as well as at the floors, elevator shafts, and central shafts of frame, frame shear, frame tube, and tube in tube structural systems; At the four corners and middle positions of raft foundation and box foundation; Multi story masonry buildings have a vertical wall spacing of 6-10 meters at the corresponding end of the horizontal wall; Adjacent column bases where the frame structure may experience significant uneven settlement; The ends of high-rise buildings correspond to both horizontal and vertical directions. Place at least 4 measuring points symmetrically along the perimeter or foundation axis of various structures. The observation reference point should be set outside the influence range of the foundation pit engineering, generally not less than 30-50 meters, and the number should not be less than two
