Abstract
The utility model discloses an embedded load case for PHC tubular pile foundation bearing capacity test, which comprises embedded load case bottom plates, a jack and a coaming, the embedded load case bottom plates comprise an upper embedded load case and a lower embedded load case bottom plate, PHC pile body connecting plates are disposed above the upper embedded load case bottom plate and below the lower embedded load case bottom plate and are fixedly connected with the upper embedded load case and the lower embedded load case bottom plate, a displacement device is mounted on the upper embedded load case bottom plate, the coaming is disposed on the periphery of the jack and is fixedly connected with the upper embedded load case and the lower embedded load case bottom plate, and a spiral bar reinforced concrete layer is poured between the jack and the coaming. The utility model is simple in structure and convenient in operation, and ensures the bearing strength and the accuracy of PHC tubular pile foundation bearing capacity detection.
Description
Technical field
The utility model relates to the checkout gear of pile body, specifically is the pre-buried load case that a kind of PHC of being used for becomes pile tube base bearingtest.
Background technology
Pile foundation is one of engineering structures base form commonly used, belong to underground concealed engineering, the construction technology more complicated, it is tight that technological process is connected mutually, the careless slightly mass defect that variform complexity such as broken pile very easily occur during construction, influence the integrality of pile body and the supporting capacity of stake, thereby directly influence the safety of superstructure.Therefore, its quality examination becomes the important means of pile foundation engineering quality control.
The utility model content
The technical problems to be solved in the utility model provides the pre-buried load case that a kind of PHC of being used for becomes pile tube base bearingtest, can satisfy and detect the requirement that PHC becomes the frictional force size of the bearing capacity of pile tube base and pile lining simultaneously, detects the data precision height.
The technical solution of the utility model is:
Be used for the pre-buried load case that PHC becomes pile tube base bearingtest, include the load box plate, jack and coaming plate, described load box plate comprises, following load box plate, the below of the top of last load box plate and following load box plate is provided with PHC pile body junction plate and with last, following load box plate is fixedly connected, described going up on the load box plate is equipped with gearshift, described jack is arranged at, between the following load box plate, described coaming plate is arranged at the peripheral of jack and with last, following load box plate is fixedly connected, is perfused with the spiral bar layer of concrete between described jack and the coaming plate.
The oil pipe of described jack is positioned at the rotating shaft of jack; Described spiral bar layer of concrete is made up of the spiral bar and the concrete that are installed between jack and the coaming plate.
The cross section of described load box plate and PHC pile body junction plate is annular, and race diameter is identical; Described coaming plate is the circular rings winding board, and diameter is identical with the race diameter of load box plate; The inner ring diameter of the rotating shaft of described jack is more than or equal to the inner ring diameter of load box plate.
The utility model is exerted pressure to the load box plate by jack, and is perfused with the spiral bar layer of concrete between jack and the coaming plate, has guaranteed bearing strength, has guaranteed the accuracy that PHC becomes pile tube base bearing capacity to detect, and simple in structure, easy to operate.
