Embodiment Construction

[0041] The present invention will be further described below in conjunction with accompanying drawings and examples.

[0042] Such as figure 1 , 2 As shown, the new multi-functional electroosmotic consolidation test device for strengthening fine-grained, low-permeability soft clay foundation includes an external visualization main system 1, which is composed of tempered glass soil sample chamber 2, and the six sides are equipped with visualization Tempered glass, which can visually observe and compare the soil settlement; and insert the measuring electrode anode A3-1 and the measuring electrode cathode B3-2. The measuring electrode adopts an iron or aluminum metal tube with a diameter of 2 cm and a slit on the surface. The electrode consists of The geotextile is wrapped and placed vertically in the soil in the barrel; the external visualization main system 1 corresponding to the measurement electrode cathode B is provided with a drainage channel 5 at the bottom, and the all-r...

Abstract

The invention discloses an electro-osmotic consolidation test device and method for consolidating a soft clay foundation. The device comprises an external visual main body, measuring electrodes used for measuring the voltage and the current of a clay body and potential measuring needles are arranged in the external visual main body, the bottom of the external visual main body is provided with a drainage channel, and a real-time image collecting system is arranged outside the external visual main body; power is supplied to the measuring electrodes by a power supply, and a voltmeter and an ammeter are connected to a loop connected with the measuring electrodes. According to the device and the method, omnidirectional comprehensive measuring is conducted on the conductivity, the clay pressure, the settlement volume, the displacement, the voltage and the current, data is automatically processed with the help of a computer, the electro-osmotic effects under the different factors are visually compared, and compared with a previous device, the device has more practicability and comprehensiveness.

Description

technical field [0001] The invention relates to a new multifunctional electroosmotic consolidation test device and operation method for reinforcing fine particle and low permeability soft clay foundation. Background technique [0002] Soft clay is widely distributed in the eastern coast of my country because of its unique properties such as high moisture content, high compressibility, and low strength, which bring inconvenience to engineering construction. Therefore, the foundation of this soil should be treated before construction. Among many ground treatment methods, electroosmosis method, as a relatively new and effective method, has been applied in engineering. Electroosmosis is a foundation treatment method that uses electric energy to strengthen the foundation. It has the advantages of fast reinforcement speed and good reinforcement effect on fine-grained and low-permeability soil. At present, the research on electroosmosis is mainly based on indoor experimental resea...
