Test method and device for bonding between concrete and pile foundation casing in steel hanging box sleeve |
abstract |
A method and device for testing the adhesion between concrete in a steel hanging box sleeve and a pile foundation casing, the test steps are: (1) building a pool and placing the pile foundation casing, and the pile foundation casing and the bottom plate of the pond are poured into one body; ( 2) Construction of the side wall of the pool and pouring of the pile foundation concrete; (3) Paste the strain gauge on the outer wall of the pile foundation protection cylinder; (4) The lower sleeve is sleeved on the outer circumference of the pile foundation protection cylinder, and the bottom adopts the ring plate and the outer wall of the pile foundation protection cylinder (5) Perform underwater pouring of concrete in the sleeve; (6) Install a jack and hanger device on the top of the pile foundation concrete; (7) After the age of the concrete in the sleeve reaches the requirement, pump water to expose the concrete in the sleeve (8) Use the hydraulic control system to control the loading of the jack, and carry out the test to obtain the adhesion data. The technology can more accurately obtain the data of the bonding force between the concrete in the sleeve and the pile foundation casing, and provide a basis for the design. |
