Embodiment Construction

[0015] Such as figure 1 As shown, the experimental device for real-time monitoring of water supply during soil freeze-thaw cycles includes a Magriot bottle consisting of a rubber upper cover 2, a glass cylinder 4, and a rubber lower cover 7. The upper end of the glass cylinder 4 is provided with a rubber upper cover 2, and the lower end is provided with a rubber lower cover 7.

[0016] The rubber upper cover 2 is provided with a through hole I, and a pressure sensor 1 is inserted in the through hole I; the lower end of the glass cylinder 4 is filled with liquid water 6, and the gas 3 is filled between the upper surface of the liquid water 6 and the rubber lower cover 7; The lower part of the glass cylinder 4 is provided with an air inlet 5 which is located in the middle of the liquid water 6;

[0017] Wherein: the front nozzle of the pressure sensor 1 passes through the through hole I on the rubber upper cover 2 and connects with the glass cylinder 4 .

[0018] The water sup...

Abstract

The invention relates to a testing device for real-time monitoring of water replenishment in a soil mass freezing and thawing cycle process. The testing device comprises a Mariotte bottle comprising rubber upper cover, a glass barrel and a rubber lower cover, wherein the rubber upper cover is arranged at the upper end of the glass barrel; and the rubber lower cover is arranged at the lower end ofthe glass barrel. The testing device is characterized in that a through hole I is formed in the rubber upper cover; a pressure sensor is inserted into the through hole I; the lower end of the glass barrel is full of liquid water; gas is filled between the upper surface of the liquid water and the rubber lower cover; a gas inlet is formed at the lower part of the glass barrel and located in the middle of the liquid water; a through hole II is formed in the rubber lower cover; and a water replenishment pipe is inserted into the through hole II. The device has the characteristics of real time, stability, reliability, convenience in use, high precision and the like.

Description

technical field [0001] The invention relates to a test equipment required for a one-way freezing process of an open system carried out indoors, in particular to a test device for real-time monitoring of water supply in the freeze-thaw cycle process of soil. Background technique [0002] Frost heaving and thawing are the two most important diseases of engineering construction in cold regions, which have brought great harm to engineering construction and operation in cold regions. Water migration and ice segregation are the most fundamental causes of frost heaving and thawing deformation, while water supply is an important parameter reflecting the water migration process. [0003] Indoors, an open system one-way freeze-thaw test is generally used to simulate the on-site freeze-thaw process. During the one-way freeze-thaw process in an open system, a Mariott bottle is generally used for rehydration. In order to obtain the water replenishment amount of the soil sample at diffe...
