Abstract

The invention relates to a model device and method used for field measuring of the blockage degree of an opening pile interior soil plug. The device comprises a test pile, an anchor pile, a datum line beam and a counter-force groove. An opening is formed in the lower end of the test pile. A bearing sheet is fixed to the top of the test pile and provided with a jack. A load sensor is arranged on the top of the jack. The top end of the jack abuts against the lower end face of the counter-force groove. A magnetic force meter base is arranged on the datum line base and provided with an electronic dial indicator used for measuring the displacement of the bearing sheet. The load sensor is connected with a value force measuring instrument. The test pile is provided with a reserved hole. An inner iron ball is arranged in the test pile and connected with a thin rope. The thin rope penetrates the reserved hole and is connected with an outer iron ball located outside the test pile. The model device is simple in structure, easy to operate and convenient to transport, mount and dismount, the requirement for the needed testing environment is low, and the opening pile blockage degrees under various kinds of soil properties can be judged.

Description

technical field [0001] The invention relates to the field of pile foundations in geotechnical engineering, in particular to a model device and method for on-site measurement of the degree of soil blockage in open piles. Background technique [0002] Pile foundations are widely used in soft soil areas and under high-rise buildings. The types are divided into steel pipe piles, concrete prefabricated piles, and pipe piles of different materials are divided into closed piles and open piles. Existing studies on the soil plugging effect of open pipe piles mostly use field in-situ tests. However, due to the fact that field tests need to meet the actual needs of future projects, the investment is often huge. It will be more complicated, and it is difficult to carry out the test in an all-round way. In this case, the on-site model test can save a lot of manpower, material resources and financial resources. Because it is a field test, the results obtained are also in line with the act...
