Description
Technical Field
The utility model relates to a basic dress static load experiment technical field especially relates to a vertical resistance to compression bearing capacity device of friction pile.
Background
The static load test refers to a test method for respectively applying axial pressure, axial uplift force or horizontal force at the position where the elevation of the bottom surface of a pile foundation bearing platform is consistent step by step according to the using function of a pile, observing the settlement, uplift displacement or horizontal displacement generated at the corresponding detection point of the pile along with time, and judging the corresponding vertical compression bearing capacity, vertical uplift bearing capacity or horizontal bearing capacity of a single pile according to the relation (namely Q-S curve) of load and displacement. The pile loading method and the anchor pile method are generally applied to the vertical compression-resistant bearing capacity of a single pile, the pile loading method needs the cooperation of a transport vehicle and a crane, and the test cost is high; the water tank is used for balancing weight, and after the test is finished, the cleanness of a test site can be influenced due to the fact that water needs to be discharged; the anchor pile method is fast to install, but for large-tonnage test piles, the weight is large, the size is large, and the transportation and loading processes are very inconvenient.
SUMMERY OF THE UTILITY MODEL
