Description

Technical Field

[0001] The utility model relates to the technical field of foundation detection, and more precisely to a pressure bearing plate for foundation detection. Background Art

[0002] Foundation testing engineering testing includes the physical properties of soil and engineering classification, soil shear strength, foundation bearing capacity, foundation treatment, types of piles and their characteristics, theoretical basis of dynamic measurement of pile foundation fluctuations, static load test of foundation and composite foundation bearing capacity, pile bearing capacity detection, pile body integrity detection, anchor locking force detection, etc. Foundation testing requires the use of pressure plates and jacks. The jacks are used to apply force to the foundation surface through the pressure plates, measure foundation deformation and pressure, and calculate the deformation parameters of the foundation bearing capacity.

[0003] The existing pressure plate cannot quickly and accurately locate and install the jack base during use. In addition, two or four displacement sensors need to be set around the jack and suspended above the pressure plate to detect the settlement data of the pressure plate during loading. The displacement sensors need to be at the same distance from the sides of the pressure plate to facilitate data comparison and achieve more accurate evaluation. The existing displacement sensors rely on manual measurement to ensure that the installation positions of multiple displacement sensors are the same, which is cumbersome to operate and has low accuracy. Utility Model Content

[0004] The utility model aims to provide a pressure bearing plate for foundation detection, which is convenient for quickly positioning and installing a jack base, and is convenient for ensuring that multiple displacement sensors can be symmetrically installed, so that the detection data is more accurate.

[0006] A pressure plate for foundation detection comprises a pressure plate body, four bearing plates are symmetrically arranged on the upper surface of the pressure plate body, a guide rod is fixedly connected between two of the bearing plates, a bidirectional screw is rotatably arranged between the other two bearing plates, two arc-shaped clamping plates are symmetrically arranged between the guide rod and the bidirectional screw, the arc-shaped clamping plates are slidably sleeved on the guide rod, and the two arc-shaped clamping plates are respectively threadedly connected to the two ends of the bidirectional screw, four groups of marking assemblies are symmetrically arranged on the upper surface of the pressure plate body, the four groups of marking assemblies are respectively arranged close to the four side walls of the pressure plate body, and the marking assemblies include a plurality of sensor installation marks arranged at equal intervals.

[0007] Furthermore, the sensor installation mark is located on the perpendicular bisector of the ridgeline of the adjacent pressure plate body.

[0008] Furthermore, the distance between the sensor installation mark and the adjacent edge of the pressure plate body is 25-50 mm.

[0009] Furthermore, four sleeve rods are symmetrically arranged on the upper surface of the pressure plate body, and a counterweight block is slidably sleeved on the sleeve rods.

[0010] Furthermore, a rotating handle is provided at one end of the bidirectional screw.
