Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation detection devices, in particular to a displacement measuring device for pile foundation static load self-balancing method tests. Background Art

[0002] The pile static load self-balancing method is an advanced test method for detecting the bearing capacity of pile foundations. The main principle of this method is to pre-bury a load box inside the pile foundation, apply loads in both upward and downward directions, and use the reaction force of the pile body itself to achieve the purpose of testing the bearing capacity of the pile foundation. It has many advantages. First, compared with the traditional static load test method, the self-balancing method does not require a large reaction frame and stacked weights, which greatly reduces the site and equipment required for the test, and reduces the test cost and difficulty. The pile static load self-balancing method can also complete the test in a shorter time, improving work efficiency.

[0003] After searching, the prior art, Chinese Patent Publication No.: CN205576985U, discloses a displacement measuring device for use in pile foundation static load self-balancing method tests, comprising an in-tube T-shaped fixing plug set on a protective tube pre-buried in the pile foundation to fix a displacement rod, the in-tube T-shaped fixing plug being provided with a displacement rod guide hole; a displacement sensor probe base being provided above the in-tube T-shaped fixing plug, the top of the displacement sensor probe base being provided with a displacement sensor probe contact panel. The displacement measuring device for use in pile foundation static load self-balancing method tests described in this utility model mainly addresses the problems of manual visual installation of displacement sensors in pile foundation self-balancing method tests that are prone to tilting, and lateral displacement of the displacement rod when it moves up and down. The use of a unified working mode makes the measurement data more reliable, more standardized, and more operational.

[0004] However, the device also has the following defects:

[0005] When installing the displacement sensor body, the bottom probe of the displacement sensor body must be pressed against the touch panel. However, the environment around the foundation pile site is relatively poor. In the prior art, it is difficult for operators to adjust the position of the displacement sensor body when installing it, making the installation work more difficult. This device does not solve this problem well. Utility Model Content
