TECHNICAL FIELD
[0001] The utility model relates to the technical field of building construction, especially relate to a dry hole concealed pile perpendicularity linear detection device. BACKGROUND
[0002] Concealed piles are commonly used in engineering, especially in the foundation treatment part. Its main function is to provide a stable foundation support for buildings, ensuring the safety and stability of buildings. In the construction of infrastructure such as airports, bridges, roads, and buildings, concealed piles play a crucial role. It not only provides foundation support for buildings, but also participates in the stability maintenance of the entire engineering structure. In addition, in some special geological conditions, such as soft soil foundation, the use of concealed piles is more common because it can provide better support to ensure the stability of the foundation.
[0003] The perpendicularity linear of the concealed pile can ensure the bearing capacity and stability of the pile foundation. If the perpendicularity deviation of the concealed pile is large, it may lead to a decrease in the bearing capacity of the pile foundation, and even tilting or breaking, thereby affecting the safety and stability of the entire building; affect the construction quality and progress, if the perpendicularity of the concealed pile cannot be effectively controlled during the construction process, it may lead to repeated adjustment and correction during the construction process, increase the construction difficulty and cost, and prolong the construction period; it will also affect the service life and safety of the building, the concealed pile with large perpendicularity deviation is easily affected by external force during use, leading to pile body bending or shearing, thereby affecting the overall structural safety and service life of the building
[0004] At present, the main methods for detecting the perpendicularity linear of dry hole concealed piles in China are manual detection and ultrasonic detection. Manual detection uses a plumb line, which can only be used for large-diameter holes, and requires manual assistance at the bottom of the well. Deep holes have safety risks, and small hole diameters limit personnel access.
