Description

Technical Field

[0001] The invention relates to the field of foundation detection, and in particular to a water conservancy project foundation detection device. Background Art

[0002] Foundation testing is an important part of ensuring building safety in construction projects. Its main purpose is to evaluate the bearing capacity, stability and deformation characteristics of the foundation to determine whether it meets the design requirements. The measurement methods of foundation testing can be divided into three categories: in-situ testing, indoor testing and non-destructive testing. In-situ testing is further divided into static penetration testing, dynamic penetration testing, standard penetration testing, lateral pressure testing and surface wave analysis.

[0003] In the related technology, the detection of the foundation of water conservancy projects generally adopts the lateral pressure test, and the detection steps include: first, use a hydraulic rotary drill to drill vertically, the hole diameter is 10-15cm larger than the diameter of the lateral pressure gauge, the hole depth needs to penetrate the soft soil layer to the stable bearing layer, the verticality deviation of the borehole is controlled to be ≤1%, and the inclinometer is used for real-time calibration; second, use a hoisting equipment to lower the lateral pressure gauge to the specified depth, first pre-pressurize with a pressure of 0.05-0.1MPa to eliminate the gap between the probe and the hole wall, then increase the pressure by 0.05-0.1MPa at each level, with an interval of 1-2 minutes, and record the data, and stop when it reaches 1.2-1.5 times the design estimated limit pressure; third, with pressure as the horizontal axis and volume change as the vertical axis, divide the elastic stage, plastic deformation stage and destruction stage; fourth, first reduce the pressure step by step to zero to avoid negative pressure causing hole wall collapse, and then lift the drill at a uniform speed to prevent disturbance of the hole wall.

[0004] With regard to the above-mentioned related technologies, in the process of foundation inspection, it is usually necessary to collect data from multiple points in the hole. Since the hole to be inspected is in a complex underwater environment, it is inconvenient for staff to observe. When the inspection equipment needs to be lowered to a deeper position in the hole, the inspection equipment is easy to touch the hole wall, causing the hole wall to collapse, which can easily lead to deviations in the foundation inspection data.
