Description

TECHNICAL FIELD The present invention relates to a composite behavior test system for performance testing of a waterproofing material corresponding to a complex deterioration condition of an underground environment,

The present invention relates to a composite behavior tester for performance testing of a waterproofing material corresponding to complex deterioration conditions of an underground environment. More particularly, the present invention relates to a composite behavior tester for fixing a test object in a test chamber, And to provide a performance data corresponding to the behavior of the structure against objective waterproofing materials by configuring the waterproofing material to be capable of setting up and down the tensile force and the torsion of the waterproofing material for the performance test of the waterproofing material corresponding to the complex deterioration condition of the underground environment And a composite behavior test apparatus.

In general, civil engineering structures are subjected to various forces by their own weight, changes in groundwater level, and flow of soil. Such a displacement stress causes serious problems such as deforming, collapsing, or vibrating the structure.

Therefore, various researches, plans, researches, designs, analyzes and evaluations are carried out in order to design the structures with necessary strength and function economically and effectively in accordance with the installed environment.

For example, concrete structures such as a roof slab, a roof, a basement of a building, various fluid storage tanks and the like may lack water tightness and rainwater or ground water may permeate.

In this case, the water impregnated in the concrete not only lowers the bonding force of the concrete itself, but also causes a crack in the concrete structure due to the volume change of the water due to the temperature change, thereby shortening the life of the concrete structure.

Therefore, the waterproofing method of concrete structures is important to prevent this, and the waterproofing materials used in such waterproofing methods should have appropriate performance and functions.

The performance of the waterproof material can be variously set according to the requirements of the structure. The long-term waterproof performance and durability of the construction structure may be deteriorated due to the salty environment, the settlement of the ground, and cracks. Therefore, leaking in underground structures greatly deteriorates the safety and usability of the entire structure, so that a method of securing perfect waterproof quality at the design and construction stages should be introduced.

The performance specifications presented in the current KS standard are minimum standards for the material performance of each waterproof material and do not guarantee proper performance for each situation. Most of the new technology waterproofing materials currently used are composite materials of various materials and waterproofing methods have been proposed. However, there is a problem that an appropriate evaluation method for the proposed new waterproofing materials is not proposed. At present, it is impossible to maintain a reliable and consistent quality level because the waterproofing method is selected and evaluated based on different standards at each site.

Therefore, it is desirable to confirm that the waterproofing materials used for waterproofing of concrete structures have appropriate performance and functions. In other words, if there is test data on how the concrete structure with the waterproof material is able to withstand the various environmental conditions that can be encountered in actual reality, the waterproofing method of the actual concrete structure can be designed economically and effectively.

The response test method for the behavior of concrete structures against waterproof materials is as follows.

First, two mortar test specimens of a predetermined size simulating the shape of a concrete structure are bonded to each other in a waterproof material (for example, in the form of an adhesive or a joint) and then placed in a test chamber. 10 ± 2 ° C) and fresh water conditions (filling the test chamber with water), and then conduct a behavior test.

For the behavior test, for example, the behavior is set to 4.5 mm (tolerance ± 0.2 mm) and the behavior speed is set to 5 mm / min. As a result, it is confirmed whether or not the water leaks into the test body.

However, conventionally, since a dedicated test apparatus for a concrete structure is not provided, accurate and objective test results can not be obtained, so that credibility and reliability of test results can not be secured. Accordingly, the present inventor has proposed a test apparatus for responding to structural behavior of a waterproof material disclosed in Korean Patent No. 10-1465943 and a test method for responding to the behavior of a waterproof material according to the test apparatus (see FIG. 1).

A standard test specimen S consisting of two test specimens S1 and S2 bonded with a waterproof layer is first prepared and fixed to the mount portion 120 in the test chamber 110 provided in the test apparatus 100 . Then, a temperature condition or a fresh water condition in the test chamber 110 is set by using the temperature adjusting unit 140 and the water tank adjusting unit 150. Then the movable motor 132 of the moving part 130 is operated with respect to the test piece S to apply a tensile force to the test piece S connected to the movable motor 132 and the connecting shaft 134 to vibrate up and down. If the connecting portion of the test body S is broken, leakage occurs to the inside of the test body S, which is leaked to the outside of the test chamber 110, and it is possible to confirm whether leakage occurs.

Accordingly, since the test conditions can be set objectively, an apparatus and a method for ensuring the credibility and reliability of the test result data can be provided.

However, the above-described behavior test of the test apparatus has a limitation that the behavior test of the test body only applies a tensile force in a simple direction. In reality, there is still a need for an improved test apparatus that can set the behavior test conditions closer to reality, because tensile forces can be applied to the structure in various directions.

In order to overcome such a problem, Japanese Patent Application No. 10-1671781 filed by the present applicant discloses a complex behavior test apparatus and method for performing a performance test of a waterproof material corresponding to complex deterioration conditions of an underground environment.

However, in the composite behavior test apparatus and method for performance test of the waterproofing material corresponding to the complex deterioration condition of the underground environment, there is a lack of detailed operation and data acquisition in the vertical direction and the lateral direction. to be.

First, a test body 10 composed of two vertically bonded upper and lower test pieces 12 and 14 is prepared. After the test body 10 is mounted on the test chamber 200, the upper test piece 12 Is connected to the upper and lower repetitive actuating part 400 and the lower test piece 14 is connected to the left and right rotary actuating part 500.

And sets at least one environmental condition among the temperature, fresh water, and flow rate in the test chamber 200 in which the test body 10 is disposed through the controller C.

For example, the temperature condition is set at a room temperature of 20 ± 3 ° C and a low temperature of -10 ± 2 ° C. Fresh water conditions are set so that the test body 10 is immersed in water by flowing fresh water into the test chamber 200.

Next, a predetermined up-down tension force and a predetermined left-right twisting tension force are simultaneously applied to the test body 10 by using the upper and lower repetitive actuating part 400 and the left and right rotary actuating part 500.

For example, the up-and-down repetitive actuating part 400 is set to a vertical vibration width of 4.5 mm (tolerance of ± 0.2 mm) and a vibration speed of 5 mm / min, The part 500 can be twisted repeatedly to the left and right by setting the lateral vibration amplitude to 2.5 mm (tolerance ± 0.1 mm) and the vibration velocity to 2 mm / min.

When the leakage of the water in the water leakage path 320 is detected by using the water leakage sensor 340, the behavior test step may be stopped and test data may be generated. At this time, the water moving along the water leakage path 320 is collected in the drain tank 360.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course, fall within the scope of the present invention.
