Measuring device for concrete permeation coefficient and measuring method

Abstract

The invention provides a measuring device for a concrete permeation coefficient. The device comprises a water injecting chamber, a water inlet pipe, an overflow pipe, a water storage container, an upper annular tray, a lower annular tray, a support frame, a lifting mechanism, a permeating water collecting funnel, a permeating water guiding pipe, a weighting container and an intelligent measuring system, wherein the water injecting chamber is communicated with the water storage container through the water inlet pipe and the overflow pipe; the support frame is respectively fixedly connected with the lower annular tray on the upper side and the lifting mechanism on the lower side; the upper annular tray is fixedly connected with the lower edge of the water injecting chamber; a sealing cushion is arranged on the lower surface of the upper annular tray; the lower annular tray is fixedly connected with the upper end of the support frame; a sealing gasket is arranged on the upper surface of the lower annular tray; the permeating water collecting funnel is arranged in the support frame; the bottom of the permeating water collecting funnel is connected with the weighting container through the permeating water guiding pipe; the intelligent measuring system is used for calculating the permeation coefficient of a test piece according to a fixed formula based on the measured time, and corresponding permeating water quality. The measuring device provided by the invention has a simple structure, high measurement precision and high measurement repeatability; the measuring method is quick and convenient and is suitable for the measurement for the concrete permeation coefficient in any places; and the invention also provides a method for measuring the concrete permeation coefficient by adopting the measuring device.

Description

technical field [0001] The invention relates to a water permeability coefficient measuring device, in particular to a concrete water permeability coefficient measuring device and a measuring method. Background technique [0002] At present, the ground of the main living places of urban residents (city squares, sidewalks, commercial streets, parking lots, etc.) is mainly paved with impermeable hardened materials such as granite, marble, asphalt, and cement. The lack of breathability, poor rain infiltration and heat absorption capacity also brings a series of problems. When it rains, due to the poor water permeability of the hardened material ground, the ground is prone to water accumulation, which brings a lot of inconvenience to people's lives; the precious water resources are lost along with the underground drainage pipes, which increases the burden on the urban drainage system; at the same time, the surface water cannot be obtained If it is well supplied, it will seriousl...
