A pile foundation manufacturing device for model testing

Abstract

The invention discloses a multifunctional device and a method for model test pile foundation processing and detection. The multifunctional device comprises a locking support arm, an inner support arm and a counter-force support arm, wherein the locking support arm, the inner support arm and the counter-force support arm are vertically fixed on a base; the center of the counter-force support arm penetrates through the counter-force section; a locking section is connected with a gasket through a longitudinal locking bolt; the inner side of the counter-force section is tightly leaned to a limiting disc; a model pile is arranged between the gasket and the limiting disc; a sleeve is arranged on the outer side of the model pile; a pressure sensor is arranged between the locking section and the gasket; a hydraulic loader is arranged between the counter-force section and the limiting disc. The multifunctional device is adopted for strain gage adhesion, paster quality detection, strain gage lead layout, model pile outer wall coating, pile calibration after model piling coating, and the like of the model pile, has advantages that positioning of the model pile outer wall strain gage and leads is facilitated, coating of a whole pile can be precisely and efficiently implemented, and model piles of relatively large rigidity can be processed, and can be widely applied to the fields of processing and detection of model piles.

Description

technical field [0001] The present invention relates to a new type of multifunctional device and method for processing and testing model piles in the field of civil engineering model tests. And the whole pile rate setting device. Background technique [0002] In the field of civil engineering construction, pile foundation is a kind of deep foundation widely used. For a long time, although the design and construction experience of pile foundations have been continuously enriched and improved, with the gradual development of engineering construction in the direction of high difficulty, problems in the use of pile foundations emerge in endlessly, requiring relevant scientific researchers to continuously study in depth. Among the many research methods, experimental research is always one of the most reliable methods. Compared with the high investment of field experiments and the inability to carry out under certain conditions, indoor experiments can be carried out with less co...

Problems solved by technology

Generally, lines are first drawn on the pile wall of the model pile to determine the sticking position of the strain gauge. For small-diameter model piles with circular cross-sections, the marking and positioning on the pile wall are more cumbersome, and it is also difficult to realize the regular arrangement of the strain gauge wires; Model pile strain is mostly measured by applying axial load to the model pile. For model piles with thicker pile walls and higher rigidity, it is not very effective to use heavy loads because of the need to apply a larger load. Suitable; due to the arrangement of strain gauges and wires on the outer wall of the pile, the coating on the side of the pile can ensure uniform wall thickness during actual operation
