Description
Technical field
The present invention relates to a kind of architectural engineering test methods, and in particular to a kind of gunite concrete impermeability test method.
Background technique
National Standard of the People's Republic of China " normal concrete long-term behaviour endurance quality test method " GB/T-50082-
Require test specimen used in concrete impermeability test for prefabricated back cut diameter 175mm, lower port diameter 185mm in 2009, high 150mm's
Solid round estrade is irregular rock, cannot direct injection molding as gunite concrete.And national standard " rock soil anchor with
Concrete spraying support engineering legislation " GB50086-2015 and professional standard " gunite concrete application technology regulation " JGJ/
The impervious method of gunite concrete and test specimen production method are not made and being explicitly indicated in T372-2016, causes gunite concrete anti-
Seeping test not can be carried out.For normal concrete can direct pouring molding, and for incorporation accelerator spray smash molding injection
Concrete is then not suitable for, and with conical die injection specimen molding (because of serious leakiness caused by rebound), pours incorporation speed with conical die
The gunite concrete molding (changing densification process) of solidifying agent all can not exact representation gunite concrete material, lead to test result
It is not met with actual conditions, without meaning is represented, cannot reflect gunite concrete really impervious situation.
Summary of the invention
The purpose of the present invention is to provide a kind of gunite concrete impermeability test methods, and solving existing impermeability test can not
Exact representation gunite concrete really impervious situation the problem of.
In order to solve the above technical problems, the invention adopts the following technical scheme:
A kind of gunite concrete impermeability test method, comprising the following steps:
S1 making sheet: in construction of shotcrete, impervious test piece plate is sprayed with condition；
S2 takes column core: cylindrical type core is drilled through from impervious test piece plate；
S3 sample preparation: wrapping up high-impermeable screed outside cylindrical type core, and round estrade impervious test piece is made；
S4 maintenance: truncated cone-shaped sample feeding standard curing room is conserved；
S5 test: impermeability test will be carried out after the round estrade impervious test piece side sealing after maintenance.
Ensure sample injection when it is identical with concrete made from practice of construction environment, be conducive to exact representation, first spray be made
Impervious test piece plate, then cylindrical type core is drilled through, rebound causes serious uncompacted problem when can avoid conical die injection specimen molding,
It is wrapped up again using high-impermeable screed outside cylindrical type core, round estrade impervious test piece is made, side wall is sealed after maintenance
Carry out impermeability test.With this available test specimen suitable for gunite concrete impermeability test, and the impermeability test number measured
According to can exact representation construction when gunite concrete anti-permeability performance.
Preferably, the side wall of the impervious test piece plate is away from the center of impervious test piece plate in the S1 making sheet step
Distance is greater than 100 ㎜, and the thickness of the impervious test piece plate is greater than 180mm.Its interior Density Distribution when impervious test piece board size is smaller
Unevenness, and be not easy to bore sample.
Preferably, the S2 takes in column core step, impervious test piece plate injection age is more than to drill through cylindrical type after 7 days
Core, in 7 days with construction environment cured under same condition.Impervious test piece plate injection age be more than after 7 days its mechanical property be conducive to brill sample, and
And 7 days and the same condition of construction environment, the exact representation of test data can be conducive to.
Preferably, the S2 takes in column core step, the diameter for drilling through cylindrical type core is 150~175mm；The S3
In sample preparation step, the size of round estrade impervious test piece be inside diameter suitable for reading be 175 ㎜, lower mouth inside diameter is 185 ㎜ and height
Degree is 150 ㎜.According to national standard GB/T-50082-2009, " die trial should use inside diameter suitable for reading for 175 ㎜, lower mouth inside diameter
The round estrade for being 150 ㎜ for 185 ㎜ and height ", the cylinder core diameter in round estrade impervious test piece obtained the big more is conducive to
The accuracy of impermeability test data, error is minimum when the diameter of cylindrical type core is 150~175mm.
Preferably, in the S3 sample preparation step, demoulding after round estrade impervious test piece forms 24 hours, and by its both ends
It wipes off, keeps cylindrical type core both ends exposed.Keep cylindrical type core both ends consistent with its internal structure, conducive to the real table of test data
Sign.
Preferably, curing time is to spray age 28 days to impervious test piece plate in the S4 curing step.
Preferably, in the S5 test procedure, using 148~162mm of diameter, height 177mm, thickness 0.3mm
Silica gel sheath is covered to be sealed in round estrade impervious test piece side surface.Using gum cover to round estrade sealing impervious test piece, operation letter
It is single, save the cost, and the setting of the size is conducive to the sealing to round estrade impervious test piece.
Preferably, the high-impermeable screed raw material include portland cement, silicon powder, sand, polycarboxylate water-reducer,
Water.Using high-impermeable screed made from this ingredient, there is very high permeability resistance, in test, water will not be from high-impermeable sand
Pulp layer exudation, it is ensured that test data for cylindrical type core performance exact representation.
Preferably, calculate according to the mass fraction, the portland cement is 28~35 parts, 1~5 part of silicon powder, sand 48~
58 parts, 0.1~1 part of polycarboxylate water-reducer, 10~16 parts of water.
Preferably, the partial size of the sand is 0.075mm~1.18mm.For the anti-permeability performance tool of high-impermeable screed
Have an impact, the particle size range of sand is smaller compared with conventional selection, is needed more smart because its selection is to be not intended to produce to test
Really.
Compared with prior art, the beneficial effects of the present invention are: it is impervious the present invention can obtain gunite concrete is suitable for
The test specimen of test, and the impermeability test data measured can exact representation construction when gunite concrete anti-permeability performance；This hair
Bright each step is conducive to the exact representation of test data；Operation of the present invention is simple and practical reliable.
