Embodiment 1

[0020] From figure 1 It can be seen that a screw compaction concrete impermeability instrument of the present embodiment includes a support base 1, a test mold 2 is placed on the upper surface of the support base 1, and a frame 3 is arranged at intervals on the table surface of the support base 1. A press 4 is installed on the top of the frame 3, the frame 3 carries the press 4, and the output end of the press 4 is provided with a screw extruding device 5.

[0021] Heat and melt the cement and butter according to a certain ratio, pour it into a shallow pan, and spread it evenly on the test surface of the test piece. The press 4 works to press down the test piece evenly. A screw extrusion device 5 is used.

[0022] From figure 2 It can be seen that the screw extrusion device 5 is composed of a horizontal fixing seat 51, a gear motor 52, an output shaft 53, an extrusion plate 54 and a sealing rubber sleeve 55. The horizontal fixing seat 51 provides horizontal support, and at ...

Abstract

The invention discloses a spiral compression type concrete anti-permeability instrument, and belongs to the technical field of the concrete anti-permeability. The spiral compression type concrete anti-permeability instrument comprises a supporting seat, racks are arranged on a table surface of the supporting seat at intervals, a press machine is arranged at the tops of the racks, a horizontal fixed set is arranged at an output end of the press machine, the lower part of the horizontal fixed seat is fixedly assembled with a gear motor, an output shaft is arranged at the bottom of the gear motor, an extrusion plate is arranged at the lower end of the output shaft, and a sealing rubber bush is sleeved at an outer ring of the extrusion plate. The gear motor drives the extrusion plate to rotateso that the extrusion plate can displace downwardly while performing autorotation, the produced extrusion force can diffuse to the outer ring along a center of a test piece, thereby enabling a bottomsurface and sides of the test piece to completely cling to a test mode. The device is simple in operation process, prominent in sealing effect, and high in success rate, the additional material is hard to leak, the material waste can be effectively avoided, and experimental cost is reduced.

Description

technical field [0001] The invention relates to the technical field of concrete anti-seepage, in particular to a screw compaction concrete anti-seepage instrument. Background technique [0002] In the process of concrete production, it is often necessary to conduct an impermeability test on the concrete to detect the permeability of the materials used in the structure against water and other liquid (light oil, heavy oil) media under pressure. The concrete impermeability tester is mainly used for concrete The impermeability test and the determination of the impermeability label can also be used to measure the air permeability and quality inspection of building materials, so it is widely used in production, construction, design, teaching and research and other fields. Usually the concrete impermeability instrument has its own test mold. Before pressing the concrete specimen into the test mold of the impermeability instrument, it is important to apply a sealing layer on the out...
