Abstract
A cylindrical concrete penetration test device comprises a cover die. The cover die is formed by connecting two semi-circle trial dies through a screw, the two semi-circle trial dies are sealed through a vertical sealing stripe, an upper circumferential direction seal rubber die belt and a lower circumferential direction seal rubber die belt which are respectively sleeved on an upper end face and a lower end face of a test piece are matched with the cover die, and a compression ring with the bottom pressed on the upper end face of the test piece is installed on the upper end face of the cover die through a bolt. The cylindrical concrete penetration test device can overcome defects of the existing concrete penetration test device, is convenient to install, small in sealing material consumption and high in mission success rate of primary installation tests, greatly lightens labor intensity, reduces environmental pollution caused by sealing materials, improves work efficiency of tests, reduces the sealing material consumption, improves mission success rate of primary tests, and effectively guarantees test quality.
Description
Technical field
The utility model relates to a kind of infiltration experiment device, especially a kind of cylinder bodily form concrete infiltration experiment device that is applicable to the permeability test of concrete and mortar.
Background technology
Domestic available coagulation soil permeability test technical regulation adopts the truncated cone test specimen; Sealing is carried out in general space of adopting encapsulant to fill between test specimen and the die trial, and frustum of a cone die trial is connected with permeameter through screw rod and O-ring seal, carries out permeability test by permeameter certain water pressure of annotating; Its encapsulant adopts usually that paraffin adds rosin, cement adds butter etc.; Also have and adopt glass silica gel, water-repellent paint, special-purpose sealing compound and rubber sleeve and bungee to seal, these methods generally all are to adopt special-purpose pressurized equipment that test specimen is pressed in the die trial, install inconvenient; And all there is a risk of seal failure; Can not single test success, the also poisonous or very much not environmental protection of smell of some material needs to consume defectives such as encapsulant.
Summary of the invention
The utility model technical matters to be solved provides a kind of cylinder bodily form concrete infiltration experiment device, can solve the defective of existing concrete infiltration experiment device, and is easy for installation, encapsulant consumption is few, and one-step installation success of the test rate is high.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of cylinder bodily form concrete infiltration experiment device; Comprise cover die, cover die is formed by connecting through screw rod two semicircle die trials, and two semicircle die trials are through vertical sealing strip driving fit; Be enclosed within the upper surface of test specimen and the last hoop caulking gum mould band of lower surface respectively and match with cover die with following hoop caulking gum mould band, the pressure ring that bottom and test specimen upper surface compress is installed in the upper surface of cover die through bolt.
Vertical sealing strip is embedded in the semicircle vertical slot of semicircle die trial.
Pad one deck rubber washer between test specimen and the pressure ring.
The cylinder bodily form concrete infiltration experiment device that the utility model provides; Through screw rod two semicircle die trials and test specimen are closely linked together, between two semicircle die trials through vertical sealing strip hermetic seal, two semicircle die trials when clamping test specimen through wedging ring the combining closely of hoop caulking gum mould band and following hoop caulking gum mould band and test specimen on the test specimen; Thereby reach the effect of hermetic seal; The installation of pressure ring realizes making test specimen be unlikely to the effect that ejected in pressure process to test specimen spacing, can solve the defective of existing concrete infiltration experiment device, and is easy for installation, encapsulant consumption is few; One-step installation success of the test rate is high; Alleviate labour intensity greatly, reduced the environmental pollution that encapsulant brings, improved experiment work efficient, reduced encapsulant consumption; Improve the single test success ratio, guaranteed test mass effectively.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the vertical view of the utility model;
Fig. 2 is that the A-A of the utility model Fig. 1 is to cut-open view;
Fig. 3 is that the B-B of the utility model Fig. 2 is to cut-open view.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3; The utility model comprises cover die 1; Through being formed by connecting, two semicircle die trials 8 are enclosed within the upper surface of test specimen 5 and the last hoop caulking gum mould band 3 of lower surface respectively and match with cover die 1 with following hoop caulking gum mould band 4 through vertical sealing strip 2 driving fits cover die 1 two semicircle die trials 8; The pressure ring 7 that the bottom compresses with test specimen 5 upper surfaces is installed in the upper surface of cover die 1 through bolt, and the bottom surface of two semicircle die trials 8 is concordant with test specimen 5 bottom surfaces.
Pad one deck rubber washer between test specimen 5 and the pressure ring 7.
During use; Through screw rod 6 two semicircle die trials 8 are closely linked together with test specimen 5; Pass through vertical sealing strip 2 hermetic seals between two semicircle die trials 8; Two semicircle die trials 8 when clamping test specimen 5 through wedging ring the combining closely of hoop caulking gum mould band 3 and following hoop caulking gum mould band 4 and test specimen 5 on the test specimen 5, thereby reach the effect of hermetic seal, the installation realization of pressure ring 7 is unlikely to the effect that is ejected to the spacing test specimen 5 that makes of test specimen 5 in pressure process.
The utility model that is installed on the test specimen 5 is installed on the test specimen station of permeameter, closely is connected with permeameter with O-ring seal, open the permeameter pipeline switch hydraulic pressure of annotating, can accomplish concrete permeability test through screw rod 6.
The size of each parts of the utility model is following:
Wall thickness 12 mm of cover die 1, high 160mm, internal diameter 189mm;
The Φ 6 of vertical sealing strip can adopt Φ 5 or Φ 8 etc. when the change in size of test specimen 5;
The diameter of last hoop caulking gum mould band 3 and following hoop caulking gum mould band 4 is 185mm, thickness 2mm;
Claims (2)
1. cylinder bodily form concrete infiltration experiment device; Comprise cover die (1); It is characterized in that: cover die (1) is formed by connecting through screw rod (6) two semicircle die trials (8); Two semicircle die trials (8) are through vertical sealing strip (2) driving fit; Be enclosed within the upper surface of test specimen (5) and the last hoop caulking gum mould band (3) and the following hoop caulking gum mould band (4) of lower surface respectively and match with cover die (1), the pressure ring (7) that bottom and test specimen (5) upper surface compresses is installed in the upper surface of cover die (1) through bolt.
