With the continuous development of science and technology, the application of various observation technologies is becoming more and more extensive. Among them, the straight observation mark of the wall and the L-shaped observation point of the bridge are two commonly used observation methods. This article will provide a detailed description of the uses of these two types of observation points to help readers better understand their application in engineering practice.
1. The use of the straight observation target of the wall.
The wall straight observation mark is mainly used to monitor the settlement and displacement of the building. During the construction process, due to the influence of various factors, the building may have the phenomenon of settlement or displacement, which will not only affect the quality of construction, but also bring hidden dangers to the safety of the building. Therefore, the use of wall straight observation markers can monitor the settlement and displacement of buildings in real time, and find and solve potential safety hazards in time.
Specifically, the wall straight observation mark is composed of a standard body, a connector and a settlement plate. The standard body is usually made of high-strength steel, and the connecting parts are screwed or welded to fix the settling plate to the standard body.
The settling plate is made of different materials and specifications according to the actual needs, such as stainless steel, cast iron, etc. During the construction process, the settlement plate is embedded in the foundation of the building, and the standard body is fixed to the surface of the building using connectors. By regularly measuring the change in the distance between the specimen and the settlement plate, the amount of settlement and displacement of the building can be calculated.
2. The purpose of the L-shaped observation point of the bridge.
The L-shaped observation point of the bridge is mainly used to monitor the horizontal and vertical displacement of the bridge. Due to the particularity of the bridge structure, its displacement has an important impact on the safety of the bridge. The L-shaped observation point of the bridge can be used to monitor the horizontal displacement and vertical displacement of the bridge in real time to ensure the safe operation of the bridge.
Specifically, the L-shaped observation point of the bridge consists of an L-shaped frame, a connecting rod and a displacement plate. The L-shaped frame is usually made of high-strength steel, and the connecting rod is screwed or welded to fix the displacement plate to the frame.
The displacement plate is made of different materials and specifications according to the actual needs, such as stainless steel, cast iron, etc. During the construction process, the displacement plate is installed at the designated position of the bridge, and the L-shaped standard frame is fixed on the bridge using connecting rods.
By regularly measuring the change in the distance between the L-frame and the displacement plate, the horizontal and vertical displacements of the bridge can be calculated.
In practice, in order to ensure the accuracy and reliability of observations, regular calibration and maintenance of observation points are required. At the same time, for different observation projects and engineering requirements, it is necessary to select appropriate observation points and observation methods to achieve the best observation effect.
In conclusion, the wall straight observation mark and the bridge L-shaped observation point are two commonly used engineering observation methods. Their application can help engineers and technicians monitor key parameters such as the settlement and displacement of buildings, horizontal displacement and vertical displacement of bridges in real time, find and solve potential safety hazards in time, and ensure the safety and quality of projects. With the continuous development of science and technology, it is believed that the application of these two observation methods will become more and more extensive.
