Embodiment Construction

[0037] The following is further described in detail through specific implementation methods:

[0038] The reference signs in the drawings of the description include: measuring cylinder 1, conduit 2, valve 21, handle 22, cylinder 3, test piece 4, joint filler 41, leak hole 42, top plate 5, base 6, cavity 61, seal Ring 62, sealing material 63, vertical column 7, water container 8.

[0039] like figure 2 and image 3 As shown, the cement concrete joint filler 41 anti-seepage test method is tested through an indoor water seepage meter.

[0040] The indoor water seepage meter includes a measuring cylinder 1, a conduit 2, a base 6, a cylindrical cylinder 3 with openings at both ends, and a test piece 4. The conduit 2 is provided with a valve 21, and one end of the valve 21 is provided with a handle 22. The internal capacity of the graduated cylinder 1 is 600ml, and the material of the graduated cylinder 1 is transparent organic glass. The upper end of the cylindrical tube 3 is ...

Abstract

The invention belongs to the technical field of water permeability testing for joint fillers and discloses a cement concrete joint filler anti-permeability test method. According to the method, an indoor water permeability meter is adopted to perform a test; the indoor water permeability meter comprises a measuring cylinder, a conduit, a base, a valve, a cylindrical tube and a test piece; the testpiece is matched with the inner surface of the cylindrical tube; a downwardly recessed joint is formed in the upper surface of the test piece; and a water leakage hole is formed in the lower part ofthe test piece. The following preparation steps are performed before the test is carried out: (1) the test piece is prepared; (2) a joint filler to be tested is injected into the joint of the test piece; and (3) a sealing material is applied onto the surface of the test piece, so that the sealing material seals the connection position of the test piece and the cylindrical tube, and the test pieceis installed into the cylindrical tube. With the test method adopted, the water permeability of the joint filler can be tested indoors, and the water seepage condition of the joint filler can be detected, and the water seepage condition of the bonding joint of the joint filler and a cement concrete wall can be also detected.

Description

technical field [0001] The application of the present invention belongs to the technical field of testing the water permeability of joint fillers, and specifically discloses an anti-seepage test method of cement concrete joint fillers. Background technique [0002] Joint filler (asphalt or other special joint filler for pavement) is filled in the joints of cement concrete pavement to prevent water from flowing or seeping under the pavement. Water seepage from the joint filler will cause early collapse damage to the cement concrete pavement on both sides of the joint. [0003] At present, a water seepage meter is often used to measure the water seepage of the joint material and the water seepage rate of the joint material, such as figure 1 As shown, the existing water seepage meter includes a measuring cylinder 1, a conduit 2, a top plate 5 and a base 6, a vertical column 7 runs through between the top plate 5 and the base 6, a cavity 61 is opened in the base 6, and a cavity...
