Abstract

The invention discloses a test pile loading method and device of an inflatable multistage water bag, belonging to the technical field of pile loading tests. The test pile loading device comprises a support device, a multistage water bag, a water bag inflation system and a water bag water injection system. The inflatable multistage water bag is divided into a plurality of layers and can be folded for storage and carrying usually. The bottom layer of the water bag is shaped as a circle, and the side wall of the water bag is provided with a plurality of independent annular gas storage bins. During the use, the gas storage bins are inflated from bottom to top by layers, the inflated water bag can automatically stand by stages to form a cylindrical water storage space for loading, and the peripheral arc line of the cylindrical water storage space is matched and fixed with the support device. The height of the multistage water bag can be regulated according to the quantity of the inflated gas storage bins, thus loading requirements on different water storage capacities are met. After the loading is finished, water in the water bag is discharged, and then gas in the gas storage bins is emitted from top to bottom, thus the water bag can be collected. The invention has the advantages of simple calculation, safety and reliability, simple equipment and convenience for construction.

Description

Technical field: [0001] The invention belongs to the technical field of bearing capacity testing of pile foundation single piles, in particular to an inflatable multi-stage water bag loading test pile method and a device thereof, and relates to inflatable multi-stage water bag loading and unloading. Background technique: [0002] In soft soil areas, when the superstructure has a large load, pile foundations are usually used due to the needs of foundation deformation and bearing capacity. Due to the inhomogeneity and complexity of the foundation soil, the bearing capacity of a single pile must first be determined when designing a pile foundation. In actual engineering, static load test is one of the most effective and commonly used methods to determine the bearing capacity of single piles. Static load tests require a large pile of carriers, usually sand bags or concrete blocks. These pile carriers have two disadvantages: (1) they require heavy machinery for loading and unlo...
