Fig. 2 is a front sectional view of an earthquake-resistant apparatus for piping for water supply and drainage according to an embodiment of the present invention.

2, the seismic system 10a of the piping for water supply and drainage is provided with a piping support 10a for supporting the piping 2a for water supply and drainage from below, And a cover 11a connected in a straight line to the pipe 12a and the tight fitting portion 12a so as to minimize the deformation of the pipe 2a in the case of an earthquake or the like on the right and left sides of the pipe support 10a, And first to third springs 31a to 33a.

The first spring 31a is installed horizontally on the left side surface of the first side support 21a and the pipe support 10a and the second spring 32a is installed on the left side surface of the second side support 22a and the pipe support 10a. And the third spring 33a is installed in a direction perpendicular to the lower surface of the third side support 23a and the pipe support 10a.

In this case, it is preferable to provide a spring fixing cap 30a for facilitating the connection of the springs to both ends of the first to third springs 31a to 33a.

The first to third sensors 31a to 33a for measuring the degree of warping of the first spring 31a to the third spring 31a to 33a when they are deformed due to an external earthquake or the like are referred to as first to third side supports 21a to 23a.

In order to minimize deformation of the pipeline 2a due to an external earthquake or the like, the pipe bracket 10a and the first brace 61a are formed in diagonal directions in addition to the first to third springs 31a to 33a, And a second brace 61b.

That is, the first brace 61a supports the pipe support 10a from the vertex direction formed by the third side support 23a and the first side support 21a, and the second brace 62a supports the third pipe And supports the pipe support 10a from the vertex direction formed by the side support 23a and the second side support 22a.

In this case, the first brace 61a and the second brace 61b have an ultrahigh strength slurry having a compressive strength of 100 MPa or more, a flexural strength of 10 MPa or more, a shrinkage strain of 0.1% or less, and an adhesion strength of 1.0 MPa or more It is packed.

Ultra high strength slurry is prepared by mixing cement, blast furnace slag, silica fume, silica sand, high performance water reducing agent, defoamer, short fiber and water. The above-mentioned mixed material may be of any kind generally used in the art without any limitation, but preferably one kind of portland cement, blast furnace cement and pozzolan cement are used for cement, and one type (4000 (6000 class), and 3 (8000 class) are used. In the case of silica fume, it is more effective to use a powder having a particle size of 100,000 to 300,000 cm 2 / g.

Generally, the ratio of the cross-sectional area to the hollow area of a steel pipe which can be used as a conventional brace has a value of 1: 5 to 1: 6. Therefore, when the ultrahigh-strength slurry to be filled has a compressive strength of 1/5 or more of the steel pipe, that is, 100 MPa or more, the compressive strength performance may be exhibited only by the ultra-high-strength slurry filled in.

In addition, the filling material is sufficient for press-fitting or filling, and if not filled tightly, there is a high possibility of occurrence of defects. In case of using coarse aggregate, it is preferable to have a slurry form.

On the other hand, when the pressed or filled slurry has a large rate of shrinkage change in length, the shrinkage change rate is preferably not more than 0.10% (0.0015 탆) because it can not secure the integrity with the steel material. Since the filling ultra high strength slurry is burdened, a high bending strength is required to facilitate crack control and shear strength transfer, and preferably 10 MPa or more.

3 is a perspective view of an earthquake-resistant apparatus installed in a dam gate according to an embodiment of the present invention.

Referring to FIG. 3, the vibration damper 10b mounted on the dam dam according to the present invention includes four damper supporting plates 21b, 22b, 23b, and 24b, three viscoelastic rubbers 31b, 32b, and 33b, Lower gap connecting members 41b and 42b, and upper and lower hysteresis plates 51b and 52b.

The damper supporting plates 21b, 22b, 23b and 24b are made of a plate-shaped steel plate having a predetermined thickness and in the form of a quadrangle. In this embodiment, all of the damper supporting plates 21b, 22b, 23b and 24b have the same thickness and size. The damper supporting plates 21b, 22b, 23b, 24b are arranged parallel to each other in a direction from one side to the other side with a predetermined clearance.

The viscoelastic rubbers 31b, 32b and 33b are attached to neighboring cavities of the four damper supporting plates 21b to 24b, which face each other. The viscoelastic rubbers 31, 32 and 33 are press-fitted into the space between the damper supporting plates 21, 22, 23 and 24 by injection, As shown in Fig.

In this case, the viscoelastic rubbers 31b, 32b, and 33b may be made of high-damping rubbers. Generally, additives such as fillers, vulcanizing agents, antioxidants and plasticizers are added to natural rubber or carbon black, In this case, the elasticity of the viscoelastic rubber can be controlled according to the proportion of the additive, and the energy dissipating ability depends on the elasticity.

Therefore, when the vibration damping device 10b is subjected to a wind load or a design earthquake, the viscoelastic rubbers 31b, 32b, and 33b absorb energy while exhibiting viscoelastic resistance and deformation among the plurality of damper supporting plates 21b to 24b. At this time, the viscoelastic rubbers 31b, 32b, and 33b behave in a completely elastic manner in the thickness direction and absorb energy while performing shear resistance in the height direction.

The upper and lower gap connecting members 41b and 42b divide the four damper supporting plates 21b to 24b into two parts so that the independent behavior occurs. The lower gap connecting member 42b is connected to the odd-numbered one of the damper supporting plates 21b to 24b in the other direction and the upper gap connecting member 41b is connected to the odd-numbered one in the other direction.

The upper gap connecting member 41b connects the two damper supporting plates 22b and 24b to one another and the lower gap connecting member 42b connects the remaining two damper supporting plates 21b and 23b to one another.

In this embodiment, two upper and lower gap connecting members 41 and 42 are used. However, when the number of the damper supporting plates 21b to 24b is increased, the upper and lower gap connecting members 41 and 42 may be increased together. In this case, May be composed of one.

The upper and lower hysteresis plates 51b and 52b are arranged such that one of the outermost damper support plates 21b and 24b is controlled so as to suppress the other behavior and, at the same time, .

4 is a cross-sectional view of a dam internal crack monitoring apparatus according to an embodiment of the present invention.

Referring to FIG. 4, the dam internal crack monitoring apparatus 10c according to the present invention is constructed such that a plurality of observation holes are drilled vertically in the direction of the dam axis with a diameter of 10 to 50 mm from the floor of the dam to the base of the dam, It is installed on the guard.

The dam internal crack monitoring apparatus 10c according to the present invention includes a dam 110c for monitoring a dam inside a dam, a first and a second optical fibers 120c and 130c, a prism 140c, a photocoupler 150c, a controller 160c, A charging portion 170c, a charging portion 180c, a circuit board 190c, and a light guide plate 192c.

The case 110c is made up of a reinforced plastic transparent cover 112c and an aluminum cup 114c connected to a pipe 115c at the bottom. The first and second optical fibers 120c and 130c optically coupled with one end of the prism 140c are inserted into the monitoring hole and the other end of the first and second optical fibers 120c and 130c is connected to the bottom of the aluminum cup 114c The liquid is drawn out to the inside of the cup 114c through the cap 115c and then the pipe 115c of the aluminum cup 114c is inserted into the guard and fixed.

The pipe 115c is formed to have a length of about 1 m and protects the first and second optical fibers 120c and 130c from being damaged from the impact or cracking on the ground. The portion of the cup 114c is inserted into the buried hole. The optical fiber 120c or 130c connected to the prism 140c is inserted through the pipe 115c connected to the bottom of the cup 114c. After inserting the optical fibers 120c and 130c, the cement paste is poured into the monitoring hole through the pipe 115c to fix the optical fibers 120c and 130c in the monitoring hole. Subsequently, the parts are assembled and housed in the aluminum cup 114c, and the cup 114c is covered with the transparent cover 112c, so that moisture and the like are prevented from penetrating from the outside.

Since the optical fiber is similar to the coefficient of linear thermal expansion, the optical fiber does not break due to thermal expansion, and the tensile strength of the optical fiber is small. Therefore, when the internal crack occurs, the optical fiber is cut immediately.

The light emitting portion of the photocoupler 150c is optically coupled to the other end of the first optical fiber 120c and the light receiving portion is optically coupled to the other end of the second optical fiber 130c. The photocoupler 150c periodically outputs the pulsed monitoring light to the first optical fiber 120c under the control of the controller 160c. And receives the reflected light transmitted from the second optical fiber 130c and transmits an electrical signal corresponding to the received light amount to the controller 160c.

The control unit 160c includes a central processing unit (CPU), a digital signal processing unit (DSP), an analog-to-digital converter (ADC) The analog to digital converter converts the analog signal provided by the photocoupler 150c into a digital signal which is analyzed by a crack detection program and is then generated as monitoring result data. The generated monitoring result data is stored in the semiconductor memory.

The crack detection program of the control unit 160c detects the crack by only the amount of light, but when the laser beam is irradiated with a certain amount of light, the amount of light received is constant. However, when the optical fiber is broken due to cracking, It is detected that the amount of received light is remarkably reduced when the cross section is small.

The wireless transmitting unit 170c includes a CDMA wireless transmitting unit and wirelessly transmits the crack monitoring result data stored in the semiconductor memory in response to the control of the controller 160c. The transmitted radio signal is transmitted to the monitoring center through a normal CDMA mobile network.

The charging unit 180c includes a solar cell film 182c, a charging circuit, and a battery 186c. The charging unit 180c charges the battery 186c with the electric energy obtained from the solar cell film 182c through the charging circuit and supplies the electric energy charged in the battery 186c to the respective circuit units at the operating voltage. The charging circuit includes an overcharge prevention circuit and an over discharge prevention circuit to protect the battery 186c. Then, the light emitting diodes 194 are illuminated at night through the control unit 160c by sensing the day and night.

That is, during the daytime, solar energy is converted into electric energy through the charging unit 180c and stored, and at night, the light emitting diode 194c is turned on with electric energy charged in the battery, and the light is emitted to the transparent cover 112c through the light guide plate 192c And is used for night illumination.

Of course, the circuitry that constantly monitors the internal cracks and sends out the monitored data to the monitoring center is constantly supplied with the operating voltage from the battery. The internal crack monitoring circuitry minimizes power consumption by minimizing power consumption and controlling cyclic operation with CMOS circuit design.

The dam internal crack monitoring apparatus 10c constructed as described above is suitable for monitoring internal cracks due to internal cracks due to the action of earth pressure and water pressure on the dam, uneven settlement of earthquake or foundation, and the like.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention.
