Abstract

The invention discloses an automatic tester for variable head permeability of soil. The automatic tester comprises a permeameter, a wireless signal transmitter, a wireless signal receiver, and a computer, wherein the permeameter comprises a water supply tank, a pressurized locating element, a penetration container, an instrument base and a water flow sensor; the penetration container is arranged on the instrument base; the pressurized locating element is arranged on the penetration container; the water supply tank is connected to the penetration container through a water supply pipe; the water flow sensor is arranged on the water supply pipe and is used for measuring the water flow input into the penetration container; the water flow sensor is connected with the wireless signal transmitter via a signal; the wireless signal transmitter is connected with the wireless receiver via a signal; the wireless signal receiver is connected with the computer via a signal. By adopting the automatic tester, the test time cycle can be greatly shortened, the test error is reduced, the cost of a communication technology is reduced, the workload for setting hardware is reduced, and the data transmission efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soil engineering, in particular to an automatic tester for variable water head penetration of soil. Background technique [0002] At present, the seepage test is an important index for calculating the permeability coefficient of each soil layer and each soil property, especially the calculation of the settlement of buildings, the seepage of deep foundation pit excavation, the seepage and piping of earth dam embankments, etc. However, the amount of each test is large, the time is long, the work efficiency is low, and there are many errors, especially in the utilization of human resources. [0003] Therefore, those skilled in the art are committed to developing a soil that can greatly shorten the test time period, reduce test errors, reduce the cost of communication technology, reduce the workload of hardware settings, eliminate interference and errors in communication networks, and improve data transmissio...
