Concrete durability water seepage collection instrument

Abstract

The invention relates to a device for detecting concrete water seepage performance in concrete durability tests, and aims at providing the device having the characteristics of accurate seepage water collection data, high seepage water collection efficiency, flexible and convenient pressure control and adjustment, high automation degree and wide application range. The concrete durability water seepage collection instrument comprises a box, a plurality of water seepage collectors vertically mounted on the upper part of the box, a water supply pressurizing mechanism and a pressure control device, wherein the water supply pressure mechanism is communicated with the water seepage collector. The concrete durability water seepage collection instrument is characterized in that the seepage water collector comprises a water collector and a seepage resisting test mold which is embedded in the top end of the water collector; the water collector comprises a water collection platform, a tubular observation window, a conical funnel and a water receiving container which are sequentially and fixedly connected from top down; the water supply pressurizing mechanism is communicated with the seepage resisting test mold through a high pressure hose; and the top end of the seepage resisting test mold is fixedly provided with a sealing pressure plate, and the water supply pressurizing mechanism is communicated with a water pipe joint on the sealing pressure plate through the high pressure hose.

Description

technical field [0001] The invention relates to a construction engineering testing instrument, in particular to a device for testing the water seepage performance of concrete in a concrete durability test. Background technique [0002] Common hydropower construction facilities are mainly concrete buildings; since concrete buildings are in high water pressure environments (such as river dams) all the year round, there are strict requirements on the durability and water seepage performance of these buildings. At present, the durable water seepage performance data of concrete buildings are obtained through the durability penetration test of concrete specimens; the specific penetration test method is as follows: [0003] ①Prepare 6 specimens for each test, and carry out pressure test at the same time; [0004] ②The test pressure starts from 0.1MP, each level increases by 0.1MP, and each level has a constant pressure of 8 hours; [0005] ③ When water seepage occurs in 3 of the ...

Problems solved by technology

[0010] ①Because the permeation water of the test piece seeps from bottom to top, it brings great difficulties to the collection of permeation water; it is very cumbersome to collect complex permeation water with manual methods and the error is too large; the technical requirements for collecting permeation water with automatic equipment High, difficult, expensive, impractical

[0011] ②Because the test water requires pure water, the equipment pressure storage tank, pressure divider pipe and other components are all made of cast iron, which is easy to pollute the water quality and is not suitable for the concrete durability water seepage test
