Description

A foundation pit dynamic measuring instrument

Technical field

The utility model relates to the field of foundation pits, and in particular to a foundation pit dynamic measuring instrument.

Background technique

The pile dynamic tester can measure the integrity of the pile body, concrete strength and some basic conditions of the foundation pit. Generally, the foundation pile dynamic tester has a built-in lithium battery, so the foundation pit dynamic tester is mainly powered by an AC charger. To charge, the on-site staff inserts one end of the AC charger into the socket and the other end into the foundation pit dynamic tester to quickly charge the foundation pit dynamic tester, which is convenient and fast.

For example, in a foundation pit dynamic measuring instrument with the patent number CN202022830331.1, it is recorded that a spring placed between the connecting rod and the measuring column can change the measuring distance of the measuring column, although the extension or shortening of the spring can change the two measuring columns. However, after the spring is extended or shortened, the positioning effect of the spring is not good. That is to say, after the spring is extended or shortened, the staff needs to manually support the spring to ensure that the spring is extended or shortened. The length is inconvenient, so that the measurement distance of the measuring column will remain unchanged. If the staff keeps manually supporting the spring, it will delay the progress of the measurement work.

In addition, when the spring is used more often, the elastic force of the spring itself will decrease, resulting in a decrease in the length recovery of the spring itself, so the measurement distance accuracy of subsequent changes to the measuring column will decrease.

Therefore, this project proposes a foundation pit dynamic measuring instrument that can easily adjust the distance of the measuring columns to solve the above problems.
