Abstract
The invention relates to a key sealing method in a test for testing the grade of concrete impermeability, belonging to the technical field of building material detection. A sealing method which replaces paraffin by rubber bands is very simple and easy to operate. The sealing method comprises the following steps of: firstly, equally dividing a standard anti-permeability test block ( specified in standards that a round table with the diameter of the top surface of 175mm, the diameter of the bottom surface of 185mm and the height of 150mm is adopted as the specimen of the permeability test) into three sections along the height direction of the round table and marking the three sections, and drawing three equant rings along the circumferential direction of the round table along the mark points; then putting the anti-permeability test block sleeved with three lines of nine rubber bands into a steel mould of an anti-permeability instrument, and hammering the bottom of the test block by a pressure machine or a hammer until the bottom of the steel mould is parallel with the bottom of the test block and the test block completely enters the steel mould. The invention has the advantage that the invention is superior to a paraffin sealing method which is frequently used by detection staffs and other sealing methods on the aspects of labor cost, labor intensity, test efficiency, data accuracy, environmental protection and the like. Through multiple tests, the key sealing method has extremely obvious effect and is convenient to master.
Description
Technical field
The invention belongs to the detection technique field of building materials, particularly relate to encapsulating method crucial in a kind of test for testing grade of concrete impermeability, be applicable to the grade of concrete impermeability test of the various model intensity of test.
Background technology
In the concrete impermeability test that detects various model intensity, encapsulating method adopts the methods of sealing with wax more at present.The concrete operations step of the method for sealing with wax sealing
1, will mark and support impervious test block and carry taking out from fog room the previous day the surface is dried;
2, be ready to sufficient paraffin and required high temperature stove and the big pallet of dewaxing;
3, prepare two high-power big blast dry ovens, be used to toast the big punching block of Anti-leakage instrument;
4, bulk crystals paraffin is put into big pallet, pallet is placed on the high temperature stove baking is fused into aqueous fully until paraffin;
5, rapidly the impervious test block side on surface drying is coated with one deck paraffin and the encapsulant (paraffin) smeared wants uniform thickness moderate, mould is gone in assurance;
6, after encapsulant is smeared and finished, from big baking oven, to take out rapidly the punching block that baking finishes, punching block (punching block will have uniform temperature to guarantee the good of sealing when putting into test block) is put in impervious test block
7, successively according to said procedure make stay a test specimen with to be installed to Anti-leakage instrument, pressurization discharges water and tests.
Above-mentioned old test encapsulating method has a lot of difficult points and shortcoming:
1, personnel dispose too much: needing has at least increased cost of labor more than three people greatly.
2, the detection cost depletions is excessive: high-power instrument uses when dewaxing and baking punching block, power consumption, and the paraffin cost is very high.
3, excessive to personnel's physical impairment: concrete impervious detection is the often detection content of contact of testing staff, concretely must try project, in the dewaxing process, produce a large amount of toxic and harmfuls, and sealing overlong time, labour intensity is very big, and that gives the testing staff healthyly brings very big negative effect.
4, the accuracy of test efficiency and test figure reduces greatly: the dewaxing process extremely expends time in, and must guarantee evenly closely knit when smearing paraffin, next punching block process of packing into is very difficult, the punching block temperature can not be too high can not be too low, otherwise the paraffin sealing is difficult to guarantee, causes pressing leaking and tests and can't begin.A large amount of time and the manpowers of whole process waste, test efficiency reduces greatly, and data accuracy is difficult to guarantee
5, be unfavorable for energy-conserving and environment-protective: country advocates energy-conserving and environment-protective energetically, testing also should avoid destroying the work of energy-conserving and environment-protective as far as possible, the paraffin poisonous and harmful, and in the fusion process often with a large amount of poisonous dense smokes, and expend a large amount of electric power, must be improved early and stop.
Summary of the invention
The object of the present invention is to provide encapsulating method crucial in a kind of test for testing grade of concrete impermeability, solved above-mentioned problem.Realized simple to operately, through repeatedly the test of long duration sealing effectiveness is very remarkable, operating personnel one people can finish, and has improved a large amount of toxic and harmfuls of eliminating such in the undirected out-of-date methods of work efficiency and energy-conserving and environment-protective greatly, and the cost that uses manpower and material resources sparingly is huge.
The present invention adopts rubber band to replace the encapsulating method of paraffin, from operating very simple easy operating, at first (regulation anti-permeability performance test test specimen adopts in the standard in the impervious test block of standard, the end face diameter is 175mm, the bottom surface diameter is 185mm, high be the round platform of 150mm) be divided into three sections and carry out mark along the frustum cone height direction, and sternly gauge point along the round platform circumferencial direction branch circles such as three that draw.As shown in Figure 1.
The Anti-leakage instrument punching block is put in the impervious test block that will package nine rubber bands in three roads then, and parallel with the test block bottom until the punching block bottom with pressing machine or hammer hammering test block bottom, test block enters in the punching block fully.As shown in Figure 4.
Adopt rubber band to replace the sealing of paraffin, step is as follows:
(1) in the impervious test block of in the GBJ82-1985 standard, stipulating, be divided into three sections along short transverse and also along the circumferential direction on Along ent, finish (the regulation anti-permeability performance test test specimen employing in the standard of three control lines, the end face diameter is 175mm, and the bottom surface diameter is 185mm, and height is the round platform of 150mm);
(2) finish behind the control line and be enclosed within (three rubber bands overlap and become one) on the first road mean line with three common bungees;
(3) be enclosed within (three rubber bands overlap and become one) on the second road mean line with three common bungees;
(4) be enclosed within (three rubber bands overlap and become one) on the 3rd road mean line with three common bungees.
(5) the Anti-leakage instrument punching block is placed in is placed on the ground (screw hole one end being arranged up).
(6) punching block (smaller diameter end faces down) is vertically put in the impervious test block that will package three road rubber bands.
(7), enter in the Anti-leakage instrument punching block the concordant termination in bottom fully until impervious test block with pressing machine or hammer the impervious test block major diameter of vertical hammering end face into shape.
(8) will be inserted in the punching block of test block on request, be put on the Anti-leakage instrument, fastening good screw.
(9) six test specimens of repeating step (1)～(8) production standard regulation all are fixed on the Anti-leakage instrument.
(10) press the standard-required start, discharge water, suppress test block, finish, press standard rating anti-permeability performance grade until test.
The invention has the advantages that, no matter in cost of labor, labour intensity, test efficiency, data accuracy, and aspect such as environmental protection all is better than the method for sealing with wax and other encapsulating methods that the testing staff uses always, through test of many times, effect is very remarkable, and grasp convenient.
