Problems solved by technology

However, there are many technical defects in the existing water seepage meter, which is mostly manifested as the water pressure is not constant and is static pressure, and the airtightness is not good, often only can realize the constant water head or variable water head measurement under the hydrostatic pressure, so , the conventional asphalt mixture water seepage tester is difficult to meet the different technical requirements in actual measurement

Abstract

The invention relates to an asphalt mixture water seepage tester comprising a pedestal, a fixed frame and a lifting platform and also provided with a specimen lower fixing device, a sleeve cylinder, a specimen upper fixing device and a piston compression cylinder. The lower part of the piston compression cylinder is provided with an intelligent electronic water meter, the outside of the piston compression cylinder is sheevedly provided with a water tank, and the right upward side of the piston compression cylinder is correspondingly provided with a piston device; the piston device is driven through a motor and a wheel gear chain transmission device, and can perform up-and-down reciprocating motion in an inner cavity of the piston compression cylinder. By adopting the above structure, the asphalt mixture water seepage tester not only can achieve variable water head measurement and constant water head measurement under a hydrostatic pressure but also can achieve water seepage coefficient measurement under a hydrodynamic pressure, thereby greatly satisfying practical measurement requirements under different conditions, and having good economic benefits and wide application prospects.

Description

technical field [0001] The invention relates to an asphalt mixture water seepage tester. Background technique [0002] In the current laboratory test and construction process of highway engineering, the water seepage coefficient of the asphalt mixture is mainly detected by the asphalt mixture water seepage tester, so as to evaluate the compactness of the asphalt mixture. However, there are many technical defects in the existing water seepage meter, which is mostly manifested as the water pressure is not constant and is static pressure, and the airtightness is not good, often only can realize the constant water head or variable water head measurement under the hydrostatic pressure, so , the conventional asphalt mixture water seepage tester is difficult to meet the different technical requirements in actual measurement. Contents of the invention [0003] In order to overcome the above deficiencies in the prior art, the technical problem to be solved by the present invention...
