Bottom cover 3-1 is first connect by step 2) with funnel 4-1, and four sealing screw rod 2-4 are passed through the control of the 3rd 4-2 and second position Hole 3-2 is placed on truncated cone-shaped bracket 5-1, and three valve test cylinder 2-1 are sealed using three valve fastening nut 2-3.Separately Metal pipe float flow meter 6-7 is connected with outlet pipe 6-6, the bottom outlet conduit 6-6 connection funnel 4-1.Nitrogen cylinder 6-5 and air pressure Pipe 6-4 is connected, and centre is connected to first pressure controller 6-2-2, then pneumatic tube 6-4 and water feeding tank 6-3 air inlet 6-3-2 phase Even, water feeding tank 6-3 water outlet 6-3-1 connection upper hose 6-1, is connected to second pressure controller 6-2-1, and upper hose 6-1 is reconnected The inlet opening 1-2 at the center top cover 1-1, so far, experimental rig is tentatively completed;
The reinforcing body sample 8-1 processed is placed on bottom cover by step 3), artificial fixed reinforcing body sample.So far, it tries It tests cylinder and reinforcing body test specimen forms annular space, complex cement slurries 9-1, including water, light water are injected in this annular space Mud and additive, three's mass ratio be 0.6:1:0.005, additive be mass ratio be 0.05:0.05:1 triethanolamine, two Ethanol amine and sodium chloride;
Step 4) is stood, and top cover 1-1 before complex cement slurries 9-1 does not solidify will be on funnel 4-1, top cover 1-1 Sealing nut 4-2 and 1-5 are tightened, and form sealed environment.So far, experimental rig all assembles and sealing finishes;
Topped up with water in step 5) water feeding tank 6-3 remotely controls first pressure by computer 7-1 after cement 9-1 final set Controller 6-2-1 makes nitrogen cylinder 6-5 provide pressure, and the water of water feeding tank 6-3 enters test cylinder 2-1 by upper hose 6-1, by the Two pressure controller 6-2-2 can clearly go up water pressure on computer 7-1.It needs to exclude reinforcing body completely before the formal beginning of test In air: water flowing under a certain pressure first, to stability of flow final vacuum process complete.When water flow passes through reinforcing body sample 8-1 is flowed out from funnel 4-1, and metal pipe float flow meter 6-7 can measure the accumulated water volume in time period, and wirelessly be sent to Computer 7-1 terminal, the water of outflow are ultimately discharged into beaker 6-8.After exhaust, tracked using computer 7-1 by metal tube The uninterrupted of suspended body flowmeter 6-7 measurement.Record the accumulative reading of flowmeter 6-7 in a period of time.It is then shut off second pressure Controller 6-2-2 stops water filling, is then turned off first pressure controller 6-2-1;
Step 6) achievement calculates: upper water pressure P0It is measured by second pressure controller 6-2-2, water injection time t is by artificially advising Determine 1min, accumulated water volume w is measured by metal pipe float flow meter 6-7, specimen finish D and specimen height L are measured by vernier caliper, Specimen cross section product A can be calculated;The relationship of water velocity v and hydraulic gradient i is v=ki in Darcy's law, therefore infiltration coefficient
Because
And because
It can be derived from
H indicates that the water-column that water pressure is converted into, calculating formula take g=10m/s2, the density of water takes 1000kg/m3, then have Formula h=100P0
When learning above-mentioned parameter, computer calculation permeability coefficient can be directly utilized;
Step 7) reinforcing body-complex cement mixture demoulding: after the test, the fastening of sealing screw rod 2-4 or more is unscrewed Nut 1-5 prizes lower top cover 1-1, bottom cover 3-1;Three valve screw 2-3 are unscrewed, three valves are pried open.Grouting and reinforcing body-complex cement Mixture demoulding is completed;
Step 8) Analysis on Results: by the variation of note medium osmosis coefficient before and after comparison slip casting, slip casting effect is evaluated.
