Description
Technical field
The invention belongs to test water cement concrete test specimen erosion test device under the attack solution flow state.
Background technology
In existing standard criterion, the erosion test of cement concrete mainly contains two kinds of methods, and a kind of is infusion method; Another kind is dry wet cycling method, and these two kinds of methods have represented the two states of cement concrete constructions in Environmental Water.But in Practical Project, the normal phase of cement concrete constructions is soaked in Environmental Water, simultaneously, Environmental Water is under the effect of head difference, can occur to flow, in the flow process of Environmental Water, reach and with environmental hydrochemistry, react salt or the colloidal sol class produced in cement concrete, the environment that just may be flowed is taken away, and cement concrete constructions is produced to erosion damage.
Summary of the invention
The object of the present invention is to provide a kind of cement concrete to move the water erosion chamber, can realize that the cement concrete test specimen is in the lower erosion test of attack solution flow state, can realize the erosion test in the solution of different etching mediums, variable concentrations, easy to operate, ambient condition is stable.
The object of the present invention is achieved like this: a kind of cement concrete moves the water erosion chamber, by chamber, liquid reserve tank and control box form, an end in chamber is arranging control box, a side in chamber is arranging liquid reserve tank arranged side by side, bottom in chamber is separated into upper strata chamber and lower floor's agitator tank by horizontal isolated grid plate by chamber, electric heater unit and motor-driven paddle wheel are being set respectively in lower floor's agitator tank and liquid reserve tank, the water inlet pipe of water pump is connecting lower floor's agitator tank, the rising pipe of water pump is connecting liquid reserve tank, the first row water valve is installed on the liquid reserve tank drainpipe, on the tank wall of the top of upper strata chamber, water inlet is being set.
While using the present invention to do the water erosion test to cement concrete, adopt following steps:
1. needs are moved to the test specimen of water erosion test and put into the erosion test case, be placed on the case isolated grid plate.
2. according to test objective and test specimen size and how many, the attack solution of preparation respective amount is some, and open circulation attack solution storage bin upper cover, and manually control the position of electric fluviograph, guarantee in cyclic process in the erosion test case that test specimen is soaked in attack solution all the time; The major part of the solution for preparing is poured in the erosion test case, regulated the attack solution circulation control valve, set the flowing velocity of circulation solution, and will wherein remain attack solution and pour in circulation attack solution storage bin, guarantee that solution submergence heating tube gets final product.
3. opening power, set time and the time interval of solution stationary temperature and three paddle wheel automatic stirrings in erosion test case and circulation attack solution storage bin on the panel of control box.
4. in process of the test, should regularly attack solution be changed according to the situation of change of actual measurement solution concentration, in the warranty test process, etching medium is even.
5. arriving test design after the length of time, can pass through two draining valves, solution in two casees is discharged, and take out test specimen and carry out next step test.
The present invention, by the solution of the different etching mediums of preparation and concentration, is placed in moving water erosion chamber difference after the length of time, can carry out to the cement concrete test specimen test of the aspects such as physical mechanics, with the variation of reaction cement concrete performance under this environmental impact.The technical essential of this chamber has four aspects: the one, but possess the liquor box of two constant temperature, erosion test case and circulation attack solution storage bin; Two is that the flowing velocity of solution between two casees can be controlled by the attack solution circulation control valve, realize solution natural flow under the effect of head difference, as far as possible the flow state of simulating natural environment; The 3rd, can regulate the position of manually controlling electric fluviograph in circulation attack solution storage bin, realize starting the electric water pump certain hour when the solution inflow reaches the water-level gauge specified altitude assignment, solution pump in circulation attack solution storage bin is entered in the erosion test case; Four is three electric stirring impellers, can guarantee solution concentration in erosion test case and circulation attack solution storage bin evenly.
The present invention has realized the erosion test of cement concrete test specimen under the attack solution flow state, and has realized the erosion test in different etching mediums, variable concentrations solution, easy to operate, and ambient condition is stable.
