Counterweight moving device for pile foundation static load test

Abstract

The invention relates to the field of counterweight moving devices, in particular to a counterweight moving device for a pile foundation static load test. The device comprises a supporting table, a guide structure, a moving structure, a driving structure, an auxiliary structure and a limiting structure, through the arrangement of the guide structure, the supporting table can be moved, the moving track can be fixed, the skew in the direction when the supporting table moves is avoided, through arrangement of the moving structure, the supporting table can be moved conveniently, power consumed inthe moving process is relatively small, the power needed when a large number of balancing weights are moved is greatly reduced in a rolling friction mode, through arrangement of the driving structure,the moving structure can be in a stored state when the supporting table does not need to be moved, through the arrangement of the auxiliary structure, the supporting table can be used for stacking and unloading the balancing weights conveniently, and through the arrangement of the limiting structure, the auxiliary structure can be fixed to different positions according to needs.

Description

technical field [0001] The invention relates to the field of counterweight moving devices, in particular to a counterweight moving device for pile foundation static load tests. Background technique [0002] A deep foundation consisting of piles and a pile cap connected to the top of the pile or a single pile foundation connected by a column and a pile foundation, referred to as a pile foundation. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation; if the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. Pile foundations are widely used in the construction of high-rise buildings, and before use, they need to pass a static load test to test the strength of the pile foundation to ensure safety. [0003] When testing the strength of the pile foundation, it is necessary to place more concrete block...

AI Technical Summary

Problems solved by technology

[0003] When testing the strength of the pile foundation, it is necessary to place more concrete blocks above the pile foundation to continuously increase the pressure to test whether the strength of the pile foundation is sufficient. During the test, the mass of the concrete blocks is relatively large, and the number of piled There are many concrete blocks, so the total mass is large and the stacking height is high. Therefore, when testing on site, it is necessary to use a crane to continuously increase or decrease the number of concrete blocks, which is not only costly, but also very cumbersome
