Road settlement plate is a kind of equipment used to monitor road settlement, and its setting is of great significance to ensure road safety and prolong service life. The following will introduce in detail the setting method and precautions of the road settlement plate.
First, the setting method.
1.Determine the subsidence observation point.
Before road construction, the location and number of settlement observation points should be determined according to the design requirements and geological conditions. Observation points should be set in representative road sections, such as fill road sections, cut road sections, bridge road sections, etc., in order to comprehensively monitor the settlement of the road.
2.Install the settling plate.
After the observation point is determined, the settlement plate should be installed according to the design requirements. The settling plate is usually composed of steel plates, steel bars, and concrete, and the steel plates are tightly bound to the concrete by fixing the steel plates to the observation point and then pouring concrete. During the installation process, the following points should be noted:
1) Make sure the steel plate is perpendicular to the ground and avoid tilting;
2) The steel plate and the concrete should be tightly combined, leaving no gaps;
3) The steel bar should be firmly fixed in the steel plate and concrete to prevent loosening.
3.Regular observations.
During the road construction process, the settlement plate should be observed regularly. The observation time is usually once a day, and after a period of continuous observation, the settlement curve is drawn according to the observation data to analyze the settlement of the road. If abnormal settlement is found, measures should be taken to adjust it in time.
2. Precautions.
1.Observational data should be accurate and reliable.
In order to ensure the accuracy and reliability of the observation data, professional surveyors should be selected to be responsible for the observation work. Surveyors should be familiar with the setting method and observation method of the settlement plate, and regularly check and calibrate the measuring equipment.
2.Adjust the construction plan in a timely manner.
If the road settlement is abnormal, the construction plan should be adjusted in time. For example, measures such as increasing the thickness of the fill and strengthening the treatment of the foundation can be taken to control settlement. At the same time, the observation time and frequency should be adjusted according to the actual situation, so as to grasp the settlement of the road in time.
3.Strengthen construction management and quality control.
In the process of road construction, construction management and quality control should be strengthened. The construction unit shall carry out the construction in strict accordance with the design requirements to ensure that the construction quality meets the requirements of the specification. At the same time, the supervision unit should strengthen the supervision and management of the construction process to ensure the quality and safety of the construction.
4.Regular maintenance and servicing of the settling plate.
In order to ensure the normal operation and prolong the service life of the settling plate, the settling plate should be maintained and maintained regularly. For example, sediment can be cleaned regularly, joints can be checked for looseness, etc. At the same time, the settling plate should be calibrated and adjusted regularly to ensure its accuracy and reliability.
In a word, the setting of road settlement plate is of great significance to ensure road safety and prolong service life. In the process of setting, attention should be paid to the accuracy and reliability of the observation data, timely adjustment of the construction plan, strengthening of construction management and quality control, and regular maintenance and maintenance of the settlement plate. Only in this way can the smooth progress and effective implementation of road settlement observation be ensured.
