Example 1:
The invention provides a concrete impermeability instrument.
In one embodiment of the invention, a concrete impermeability instrument comprises an impermeability instrument body 100, a control system and a liquid supply system which are arranged in the impermeability instrument body 100, wherein a workbench 1 is arranged on the top surface of the impermeability instrument body 100, a test die holder 2 is arranged on the workbench 1, a water inlet groove 3 and a water inlet hole 4 are arranged on the test die holder 2, and the concrete impermeability instrument further comprises a connecting sleeve 5, a test die 6 and a bracket 7, wherein the connecting sleeve 5 is sleeved on the test die 6 and is used for being detachably connected with the test die holder 2 so as to mount the test die 6 on the test die holder 2; the bracket 7 is detachably mounted in the test die 6, the bracket 7 comprises a support frame 8, a plurality of limiting assemblies 9 and a tray 10 for placing a test piece 200, an infusion pipeline 11 communicated with the water inlet tank 3, the limiting assemblies 9 and the inner cavity of the tray 10 is formed in the support frame 8, a scraping rod 12 for pushing and scraping sealing materials is formed on the support frame 8, and a sealing cover 13 is detachably mounted at one end, far away from the test die holder 2, of the test die 6.
Specifically, the concrete impermeability instrument can adjust parameters such as test pressure, pressing time and the like through a control system in the impermeability instrument body 100; the liquid supply system can provide stable water pressure for the whole test process so as to simulate the water pressure possibly encountered by the test piece 200 in the actual use process. Further, as shown in fig. 1 to 12, when the concrete impermeability instrument of the present invention is used, since the bracket 7 is detachably installed in the test mold 6, and the bracket 7 includes the supporting frame 8, the plurality of limiting components 9 and the tray 10 for placing the test pieces 200, a tester can take the bracket 7 out of the test mold 6 and put the plurality of test pieces 200 into the plurality of trays 10 in a one-to-one correspondence, after each test piece 200 is put into the tray 10, the tester coats the side wall of the test piece 200 with sealing materials, the sealing materials are paraffin or butter in the prior art, and the like, and because the scraping rod 12 is formed on the supporting frame 8, the tester can uniformly push and scrape the sealing materials by rotating the test piece 200, thereby ensuring the tightness of the test pieces 200 in the test mold 6 and the accuracy of the test results, and the structural design is simple and the use is reliable.
It will be appreciated that when the existing concrete impermeability apparatus is used, the test mould 6 is usually mounted on the test mould base 2 through a plurality of bolts, and in this way, although the test mould 6 can be stably mounted, the operation steps of screwing the bolts are repeated and complicated, thus not only increasing the labor intensity of test personnel, but also reducing the mounting efficiency of the test mould 6. In the concrete impermeability instrument, as the connecting sleeve 5 is sleeved on the test die 6 and is used for being detachably connected with the test die seat 2, the detachable connection mode can be screw connection, the screw connection is convenient to detach and has certain tightness, after a tester puts the bracket 7 provided with the test piece 200 into the test die 6, the test die 6 is synchronously driven to move downwards by rotating the connecting sleeve 5 in screw connection with the test die seat 2, so that the test die 6 can be firmly mounted on the test die seat 2, the operation is simple, the mounting step of the test die 6 is simplified, the labor intensity of the tester is lightened, and the mounting efficiency of the test die 6 is also improved; meanwhile, the sealing cover 13 is detachably arranged at the upper end of the test die 6, the sealing cover 13 and the test die 6 can be in threaded connection or overturning and clamping connection, after the test die 6 is arranged on the test die seat 2, a tester covers the sealing cover 13, and at the moment, the sealing cover 13 is abutted against the top of the support frame 8, so that the tightness of the test piece 200 in the test die 6 can be improved, the whole bracket 7 can be limited in the vertical direction, the test piece 200 is prevented from being driven to be separated from the test die 6 upwards under the action of a liquid supply system in the test process, and the use is reliable.
In addition, after the test die 6 with the test pieces 200 is installed, the liquid supply system supplies water into the water inlet tank 3 through the water inlet holes 4, and as the support frame 8 is internally provided with the infusion pipeline 11 communicated with the water inlet tank 3, the plurality of limiting assemblies 9 and the inner cavity of the tray 10, the water in the water inlet tank 3 can flow into the plurality of limiting assemblies 9 and the inner cavity of the tray 10 through the infusion pipeline 11, and at the moment, the plurality of limiting assemblies 9 respectively move under the action of water pressure until being abutted with the corresponding test pieces 200, so that each test piece 200 is firmly abutted to the tray 10, random shaking of the test pieces 200 relative to the tray 10 is avoided, and the accuracy of test results is ensured; meanwhile, under the continuous water supply and pressurization of the liquid supply system, the inner cavity of the tray 10 is filled with water gradually, and after the inner cavity of the tray 10 is filled with water, the liquid supply system maintains constant pressure, so that the impermeability test of a plurality of test pieces 200 is realized, and the structural design is ingenious and reasonable.
It should be noted that, in the concrete impermeability apparatus widely used in the prior art, a group of test pieces generally includes 6 test pieces in a single test, that is, 6 test pieces are simultaneously installed on the impermeability apparatus body 100 to perform impermeability performance test, so in the concrete impermeability apparatus of the present invention, 6 test mold bases 2 are correspondingly disposed on the workbench 1 of the impermeability apparatus body 100, while in the concrete impermeability apparatus of the present invention, a plurality of test pieces 200 can be placed in a single test mold 6 through the bracket 7, and water pressures with different magnitudes can be provided to each test mold 6 through the control system and the liquid supply system, so that impermeability performance test can be performed on a plurality of test pieces 200 in a single test process, thereby greatly improving test efficiency. It can be understood that, in the actual use process of the concrete impermeability instrument, if two test pieces 200 are placed in a single test die 6 through the bracket 7, impermeability performance tests can be simultaneously carried out on the two groups of test pieces 200; if three test pieces 200 are placed in a single test die 6 through the bracket 7, the impermeability test can be performed on two groups of test pieces 200 at the same time, and so on.
In addition, it is obvious that compared with the concrete impermeability instrument capable of realizing impermeability test of multiple groups of test pieces in the prior art, the concrete impermeability instrument can realize impermeability test of multiple groups of test pieces 200 by arranging simple structural components such as the bracket 7, the sealing cover 13 and the like on the existing impermeability instrument body 100, and a tester does not need to reorder the concrete impermeability instrument for multiple groups of test pieces, so that the input cost of the test is greatly saved, and the concrete impermeability instrument has good economical efficiency, is particularly suitable for middle and small user units and is worthy of popularization.
It should be noted that, the control system and the liquid supply system in the permeation resistant engine body 100 are all mature prior art, and are not described herein, and the detailed constituent structures related to the control system and the liquid supply system are not shown in the drawings of the specification. The invention aims at solving the problems of low test efficiency, high input cost and poor economical efficiency of the traditional concrete impermeability instrument when a plurality of groups of test pieces are tested.
