Abstract
The invention discloses a test die for a concrete impermeability test, which has certain improvements on the conventional test die for the concrete impermeability test. Referring to a detailed drawing 1, permanent screw-down pressing devices (8, 9 and 10) are arranged on an original test die; for the improved test die, the operations of dismounting the pressing devices, reversely placing the pressing devices on a tester platform and the like are not needed after finishing the wax-sealing between a test block and the test die, but, the pressing devices are not dismounted and the test die is not placed reversely, and the pressing devices are directly placed and fixed on the tester platform to perform a test after screwing down the test block and pressing the test block against the test die, thereby overcoming the influence on the accuracy of the test result due to the water seepage which is caused by wax-sealing cracking between the test block and the test die because of the operations of dismounting a pressure device, cooling the test die, placing the test die reversely and the like. So the improved test die provides a forceful guarantee for the accuracy of the concrete impermeability test result and convenient operation, and obtains a very good effect in application.
Description
Technical field:
Civil engineering work detects with the impervious index of water-tight concrete, and this impervious experiment is applicable to die trial measures the concrete impervious grade in water-tight concrete test block sclerosis back.
Background technology:
Detail drawing 1, this technology tradition die trial is a bottom interior diameter 186mm, top inside diameter 176mm, height is the frustum cone cylinder of 150mm, correspondingly make concrete test block 2 by this die trial 1 size, sclerosis reaches the boiling hot wax 3 of certain intensity rear perimeter edge, adopting special-purpose pressue device 4 that test block is pressed into die trial by two people then treats to withdraw from pressure again after hot wax solidifies, the die trial reverse up and down (the die trial bottom down) of taking out the band test block is installed on the impervious experiment porch 5, and fixing with bolt 7, plus-pressure water 6 is done the impermeability test of test block then.In this process owing to withdraw from that pressure is got die trial and because the die trial cooling strain, very easily cause die trial to produce relative slip with wherein test block, the layer of sealing with wax that has solidified between the destruction can not guarantee the sealing between test block and the die trial, thereby seep water between test block and the die trial when causing experiment, can not whole punching press test blocks of warranty test press water and the accurate impervious grade of measuring test block.In die trial, take out also inconvenience of test block after test finishes in addition, need reuse special-purpose pressue device test block is extruded out from die trial.Like this operation effort, time-consuming, complex procedures and can not the warranty test result accurately.Therefore based on above-mentioned 2 we organize the scientific and technical personnel of research and development centre to revise testing program repeatedly.The final above-mentioned two problems development cost invention achievement that solves, detail drawing 3, easy disassembly, the die trial of good sealing effect has improved the precision of test findings, and is time saving and energy saving and reduced cost.
Summary of the invention:
Detail drawing 2, the present invention is conversely upper and lower with traditional die trial 1, bottom interior diameter 176mm, top inside diameter 186mm, high 150mm, be provided with pressue device 8,9,10 simultaneously at the die trial top, test block 2 is pressed into die trial through pressue device in the die trial and seals with wax, pressue device in the requirement die trial is implemented pressurization always and is held out against test block in die trial, die trial can not occur and destroy and seal with wax with the relative slip of test block.Like this with regard to solved test block preferably and after die trial is sealed with wax again decompression remove special-purpose pressue device operation and the die trial cooling makes the relative problem of sliding and sealing with wax and destroying and seep water with die trial of test block, test simultaneously and loosen the test block under pressure water action of die trial top pressue device after finishing and also easily from die trial, take out.

Embodiment:
1. concrete impermeability test is heated to 65～70 ℃ with die trial 1 in baking oven.
2. with hot wax 3 roller coating to test block 2 peripheries.
3. die trial is put in the test block of will waxing rapidly.
4. tighten jack unit 8,9 (nut 10 screws up with a wrench) test block is pressed into die trial, implement sealing with wax between test block and die trial.
The die trial that 5. test block 2 will be housed is fixed on the test instrument platform 5 with bolt 7.
6. open pressure water valve 6 pressurising test blocks, do impermeability test.
7. test finishes, and the hydraulic pressure that keep-ups pressure is constant, unclamps jack unit nut 10 with spanner, and test block is extruded out by press water from die trial.
8. the closing presure water valve is removed the set bolt 7 between die trial and experiment porch, can take out die trial, and test finishes.
Claims (1)
1. the concrete impermeability test die trial is that internal diameter size base diameter 176mm is made in the die trial on the impermeability test instrument, top diameter 186mm, height is the frustum cone cylinder of 150mm, the additional test specimen of installing holds out against prepressing device at each die trial top, and test block is fit into after the die trial prepressing device and holds out against test block always and no longer need release and oppositely be placed on to wait these operations on the test instrument platform.
