Embodiment
[0028] An indoor test device for model pile combined load, its structure is as follows Figure 1 to Figure 5 As shown, during the test, first fill the prepared soil in the model tank 1 according to the test requirements. The model tank 1 is formed by pouring reinforced concrete and embedded in the foundation. The model tank 1 of this embodiment is filled with two Layer soil, this test device can be used for pre-embedding and static pressure setting tests on prefabricated piles, and pouring holes into cast-in-situ piles to form piles, and has a wide range of applications.
[0029] Insert the model pile 13 into the model groove 1, and set L-shaped reaction beams 2 on both sides of the model pile 13. The L-shaped reaction beams 2 include two identical L-shaped beams welded by two sections of channel steel , that is, each L-shaped beam includes a vertical side and a horizontal side, and the horizontal side is fixed to the model groove 1 by embedded bolts 9; No. 1 connecting rod 10...

The invention relates to an indoor experiment device of combined loading of a model pile. The model pile is arranged in a model tank in an inserted mode, the device comprises L-shaped counter-force beams located on the two sides of the model pile, a main beam located on the top of the model pile and a loading device connected with the model pile or the main beam through pulleys and steel cables, the L-shaped counter-force beams are fixed on the top of the model tank, and the pulleys are fixed on the L-shaped counter-force beams respectively, and the loading device applies vertical loading on the model pile; when the loading device is connected with the model pile through the pulleys and the model piles, the loading device applies horizontal loading and bending moment on the model pile. Compared with the prior art, by means of the indoor experiment device of combined loading of the model pile, combined loading experimental testing can be conducted on pile foundation models with large size and multiple types in multi-layered soil, the applying height of horizontal loading can be controlled, eccentricity of vertical loading to a pile body can be adjusted, the bending moment of the pile body at different positions is controlled, and the bearing performance of a file foundation under combined loading is well analyzed.
Description
technical field [0001] The invention relates to the field of model tests, in particular to an indoor test device for combined loads of model piles. Background technique [0002] With the rapid development of economic construction, pile foundation technology has been widely used in our country, and has been popularized in almost all engineering construction fields in the country, and has broad development prospects. Many scholars at home and abroad have made a lot of explorations on the mechanism of pile-soil interaction and achieved a lot of results. However, because the soil is a complex three-phase medium, the pile-soil interaction relationship becomes very complicated, and the existing research lacks a systematic Theoretical analysis and experimental data accumulation. With the widespread use of pile foundation engineering, the load on pile foundation is more and more the combination of vertical load and horizontal load in a certain ratio and sequence. Due to the lack o...
