Pile foundation static loading test device

Abstract

The invention discloses a pile foundation static loading test device. The device is characterized in that an ejector rod is composed of a base section ejector rod and linkage section ejector rods, the base section ejector rod is a cylinder with a base section head cover, and the lower part of the base section ejector rod is provided with a base section flange plate; the linkage section ejector rods are hollow cylinders and the two ends of the linkage section ejector rod are provided with linkage section flange plates, and the base section flange plate and the linkage section flange plates are fixed together through a bolt; the linkage section flange plates of two linkage section ejector rods are fixed together through the bolt, and the base section ejector rod and linkage section ejector rods are sleeved on a pile to be tested; a connecting rod is composed of an outer ring connecting rod and an inner ring connecting rod, one end of the outer ring connecting rod is articulated on the base section ejector rod, and the other end of the outer ring connecting rod is articulated on a soil-bearing base; and one end of the inner ring connecting rod is articulated on the linkage section ejector rods, and the other end of the inner ring connecting rod is articulated on the soil-bearing base. The test device provided by the invention has the advantages that steel beam size of a counterforce device is decreased, the assembling is convenient and rapid, the applicability is larger, the construction operation is more rapid, the waste is not generated in a testing process, thus the device is energy-saving, is environmentally-friendly, and the experimental cost is low.

Description

Technical field: [0001] The invention relates to the field of construction technology, and more specifically to equipment for carrying out static load tests of pile foundations in the field of construction. It is used for pile-loading counterweights during static load tests such as prestressed pipe piles, sinking pipe piles, bored piles, etc. . Background technique: [0002] In the pile foundation static load test, the reaction force between the action and the upper part of the pile is provided by the reaction force device. The ease of use of the reaction force device not only affects the cost of the pile foundation static load test, but also affects the results of the pile foundation static load test. ; At present, the pile foundation static load test reaction device is commonly used for pile-load reaction beam device and anchor pile reaction beam device. [0003] The anchor pile reaction beam device generally requires a suitable pile position arrangement around the test pile. If...
