Abstract

The invention provides a vertical pressure-resistant static load test device for engineering piles. The device comprises a primary beam, a secondary beam, base template beams, a jack and pull rods, wherein a test pile is embedded into the ground and is perpendicular to the horizontal plane, the jack is placed on the top surface of the test pile, the primary beam is arranged right above the jack, the secondary beam is placed above the primary beam in a full pavement manner and is perpendicular to the primary beam, the two base template beams placed on the ground are arranged on two sides of the test pile respectively and are perpendicular to the placement direction of the primary beam, clamping grooves used for mounting of the pull rods are correspondingly formed in the secondary beam and the base template beams, and the pull rods are mounted in the clamping grooves, so that the secondary beam and the base template beams are integrally connected. The weight of pressure weights on the base template beams and the secondary beam can be used in a test, the tonnage of upper heaped loads and the heaped load height are reduced, meanwhile, the overall center of gravity is reduced, the overturning moment is smaller under the conditions of the same inclination angle and overload weight, and accordingly, the safety is improved.

Description

Technical field [0001] The invention relates to the technical field of engineering pile detection, in particular to a vertical compressive static load test device for engineering piles. Background technique [0002] In related technologies, the inspection and acceptance of engineering piles in construction projects generally include pile integrity and bearing capacity testing. Among them, the vertical compressive bearing capacity test of a single pile is an important content in the bearing capacity testing. The existing engineering pile single pile vertical compressive bearing capacity test is mainly based on the heap loading method, and its test capacity largely depends on the tonnage of the test platform. However, the existing single pile vertical compressive bearing capacity test devices are all built up separately. As the test tonnage increases, its safety and load performance decrease. Summary of the invention [0003] In order to solve the above problems, the present invent...
