Test box for flowing water eroding cement concrete

Abstract

The invention belongs to a test device for a test that a cement concrete test piece is eroded by flowing eroding liquid. The test device comprises a test box, a liquid storage tank and a control box, wherein the control box is arranged at one end of the test box; the liquid storage tank is parallel to the test box and arranged on one side of the test box; the test box is divided into an upper layer of test box and a lower layer of stirring box through a horizontal isolating grid plate at the lower part of the test box; electrical heating devices and stirring impellers are respectively arranged in the lower layer of stirring box as well as the liquid storage tank; a water inlet pipe of a water pump is connected with the lower layer of stirring box; a water outlet pipe of the water pump is connected with the liquid storage tank; a first water drainage valve is mounted on a water drainage pipe of the liquid storage tank; a water inlet is formed in the wall, at the upper part of text box, of the test box. According to the test device, the test that the cement concrete test piece is eroded by the flowing eroding liquid is realized, and the tests that the cement concrete test piece is eroded by different eroding media and liquid of different concentrations are realized. The test device has the advantages of convenience in operation and stable environmental conditions.

Description

technical field [0001] The invention belongs to an erosion test device for testing a cement concrete specimen in a flowing state of an erosion solution. Background technique [0002] There are mainly two methods for the erosion test of cement concrete in the current standard specifications, one is the immersion method; the other is the dry-wet cycle method. These two methods represent the two states of cement concrete structures in environmental water. However, in actual engineering, cement concrete structures are often soaked in environmental water. At the same time, environmental water will flow under the action of water head difference. During the flow of environmental water, the cement concrete and the chemical reaction with environmental water will Salts or sols may be taken away by the flowing environment, causing erosion and damage to the cement concrete structure. Contents of the invention [0003] The purpose of the present invention is to provide a cement concre...
