Abstract
The invention discloses a plastic concrete compressive strength quality detection device and a test method, and relates to the technical field of plastic concrete quality detection. The device comprises a cylinder; a measuring head, arranged in the cylinder; a driving device, used for driving the measuring head to move along the radial direction of the cylinder; a first detection device, arranged in the measuring head and used for detecting the displacement of the measuring head in the radial direction of the cylinder; and a second detection device, arranged in the measuring head and used for detecting the pressure borne by the measuring head in the radial movement. By collecting the penetration resistance and penetration depth data of different depths in the drilled hole, the compressive strength of the plastic concrete wall at different depths is accurately obtained, finally the representative value of the compressive strength of the drilled hole is obtained, the uniformity and integrity of the wall in the depth direction are evaluated, the defect position is accurately positioned, the quality of the wall is ensured, and the engineering safety is ensured.
Description
technical field [0001] The invention relates to the technical field of plastic concrete quality detection, in particular to a plastic concrete compressive strength quality detection device and a test method. Background technique [0002] Plastic concrete has mechanical properties and deformation properties between soil and ordinary concrete. The elastic modulus of plastic concrete is similar to the elastic modulus of the foundation, which has greater flexibility and can better adapt to the deformation of the foundation. Plastic concrete has good crack resistance and earthquake resistance; good impermeability, which effectively reduces the leakage of cut-off walls; good workability, long final setting time and low strength, so that It has the advantages of good construction and easy operation. The plastic concrete cut-off wall can be combined with the foundation to bear the force, and has a much larger ultimate deformation capacity than ordinary concrete. Plastic concrete ...
