Improved earth pressure gauge

An improved earth pressure gauge comprises an outer protective shell, a collector is arranged in the outer protective shell, a sliding plate is arranged in the collector, a weightometer is arranged below the sliding plate, a soil depth detector is fixedly arranged above the sliding plate, and a circulation gap is formed between the outer protective shell and the collector. And a convex ring is arranged at the upper part of the outer protective shell and is arranged at the top of the outer protective shell in an abutting manner. According to the device, the soil depth detector is adopted to feed back the erosion amount of soil in real time, the weighing meter can also play a good correction role in some specific places, then the structure arranged in a sleeving mode is used for avoiding strong interference of external soil, and although a part of timeliness is lost, the erosion state can still be reflected well. 一种改良型土压计，包括一外保护壳体，在外保护壳体内设有一收集器，在收集器内设有一滑动板，在滑动板的下方设有一称重计，在滑动板的上方固设一土壤深度检测器，所述外保护壳体和收集器之间设置有流通间隙；在外
