Description

Package Faucet {DRAINER FOR PAVEMENT}

The present invention relates to a pavement faucet for effectively draining the infiltration water flowing through the asphalt in the roads and bridges, more specifically to facilitate the discharge of the infiltration water utilizing the flexibility of the characteristics of the spring, The present invention relates to an improved package delivery device to ensure the convenience of construction even when the construction surface is not smooth or curved.

In general, roads and bridges, such as to install a water treatment device for effectively draining the infiltration water flowing into the lower part of the asphalt.

However, if the insulated package does not process the infiltrated water and leaves residual water when the package is drained, the general ascon pavement may be lifted due to corrosion of the bottom plate and poor adhesion to the package when the bottom plate is made of steel. do.

In the case of concrete slabs, the corrosion of reinforcing bars due to the inflow of infiltration water between the cracks of the bottom plate is concerned, and the pavement life is shortened due to oxidation of the pavement by residual water in the asphalt pavement. In addition, the pavement is subjected to the East Sea in winter, as well as the pavement of the bridge as well as the pavement of the general road, and the pavement damage caused by repeated traffic loads also occurs.

In particular, the pavement end adjacent to the protection facility of the bridge and the pavement end adjacent to the curb on the general road remain the most vulnerable part of the pavement breakage because sufficient pavement material cannot be secured. Therefore, the water treatment apparatus is used for the part which needs to process permeate water and residual water in this way.

7 shows a hole pipe, which is a water supply device 1 according to the related art. This was formed by forming a plurality of holes 12 on the pipe 10 made of plastic material. However, in the conventional water treatment apparatus 1, the holes 12 of the pipe 10 are formed by particles of asphalt pavement or the like. In many cases, the drainage capacity was blocked, and since the pipe 10 material is plastic, it expands due to the asphalt laying temperature, causing damage to the joints and the like.

In addition, in the curved part, the workability was remarkably reduced, and the workability of the field was also poor.

Therefore, at present, it is common to carry out repair when the package is broken without separately treating the permeate water penetrating the package and the residual water on the bottom of the package. However, the influence of such permeate and residual water may damage not only the package but also the top plate of the bridge, and there are many difficulties in evaluating or repairing such damage. In this situation, in order to maintain the function of the package and to ensure the durability of the road and bridge, it is necessary to treat the infiltration and residual water of the package.

The present invention has been made to solve the conventional problems as described above, the purpose is to facilitate the discharge of permeated water, and improved to ensure the convenience of construction even when the construction surface is not smooth or curved It is to provide a package receiver.

The present invention, in order to achieve the above object, in the pavement power supply device for effectively draining the infiltration water flowing through the asphalt in the road and bridge, etc., having a spring-shaped body portion, the wire diameter of the body portion The pitch between (d) is to provide a pavement faucet characterized in that the size is made smaller than the particles of the asphalt pavement.

As shown in Figs. 1 to 3, the package delivery device 100 according to the present invention has a spring-shaped body portion 105, the pitch between the element diameter (d) of the body portion 105 ( p) is smaller than the particles of the asphalt pavement.

Therefore, the present invention is a package delivery device which has a structural strength and convenience of construction as a kind of perforated pipe for drainage of infiltration water and residual water at the bottom of the package.

In the present invention, since the body portion has the shape of a general spring, the pitch (p) interval of the spring induces the inflow of water and residual water, and serves to prevent the package material from penetrating into the perforated tube. The shape of the spring is very advantageous in terms of workability because the ease of construction is secured even when the bottom of the package is not smooth or curved due to its flexibility.

In addition, the present invention is to be buried in the pavement layer, so the present invention must be able to maintain the original function of the power supply device against the external load such as the wheel load of the vehicle, so in the present invention, the buckling strength through securing the thickness and cross-sectional diameter of the spring Also secured.

In the spring-type raceway apparatus 100 of the present invention as shown in FIG. 1, if the pitch p is too large, there is a risk that the asphalt mixture may flow into the raceway, and if it is too small, the manufacturing cost may be more than necessary. , It is important to determine the appropriate pitch (p), and also the outer diameter and the small diameter (d) to ensure the strength of the spring-type hydrometer 100 can maintain the circular shape under asphalt compaction load and traffic load You must decide.

Therefore, in the present invention, after determining the representative shape of the spring-type hydrographic apparatus 100 as shown in Table 1 in consideration of Equation 1 and actual construction conditions (asphalt aggregate size, asphalt pavement compaction load, traffic load, etc.) The wheel tracking test, which is widely used in the package test, was conducted to evaluate the adequacy of the shape of the spring-type water repelling apparatus 100.

Where h is the thickness of the spring, R is the radius of the spring section, q is the external load, ν is the Poisson's ratio of the spring, E is the spring modulus, and, cr is the buckling load.

② Test body production

The size of the indoor test body was 30cm x 5cm x 30cm mold 107 used for the conventional wheel tracking test, and the spring-type hydrometer 100 was installed on the actual bridge for the outer diameter 12mm, 18mm, and 25mm respectively. Under the same conditions, it was arranged along each part of the mold 107, and it is not a shape that is arranged in the actual bridge, but the reference device 100 is arranged in the center of the test body along the curved part for reference. At this time, the installation direction of the curved portion was made into two types of A-type and B-type in consideration of the wheel tracking test direction.

③ Wheel tracking test condition

Test body curing: Indoor temperature 24 hours, Test temperature 6 hours (60 ℃)

④ Test method

Set the wheel ground pressure to 6.4kg / ㎠ to adjust the tester ground pressure.

For the setting of the tester, the wheel driving speed, driving distance, etc. were adjusted, and the total number of driving was set to 1600 round trips.

In order to prepare a test specimen, 150 ℃, 15 ℃ and 13mm asphalt mixture were put into a mold capable of producing a specimen of 30cm x 30cm x 5cm, a roller-shaped pressure plate having a surface temperature of 150 ℃ was placed, and a constant pressure of 5kg / ㎠ was applied thereto. Produced by compacting once.

After curing for 24 hours at room temperature for curing the test body, it was cured at 60 ℃ from 6 hours before the test run.

Then, the vehicle is run for 1,500 round trips for 75 minutes with wheels to the front (10 cm from the front), the center (15 cm from the front), and the rear (20 cm from the front).

⑤ Test result

After testing the wheel tracking test of the A-type and B-type wheel tracking test for the three spring-type hydroponics 100 of 25 mm, 18 mm, and 12 mm, respectively, the wheel tracking test was carried out to investigate the inflow and shape deformation of the asphalt mixture. Table 2 shows the results observed using the endoscope.

Outer diameter (mm) Test Body Type Inlet Mixture Inlet (%) Shape change Outer straight part Medial curve Outer straight part Medial curve 25 A Within 5% Within 15% none none B Within 5% Within 15% none none 18 A Within 3% Within 10% none none B Within 3% Within 10% none none 12 A Within 1% Within 1% none none B Within 1% Within 1% none none

As a result of the wheel tracking test as described above, if the pitch (p) interval of the spring-type hydrometer 100 is [1.67 x wire diameter (d) ≤p ≤ 2 x wire diameter (d)], the problem of the inflow of the asphalt mixture is In addition, it was evaluated that the deformation of the spring-type watering device 100 did not occur with respect to the outer diameter and the small diameter d determined as the representative shape. That is, if the pitch p is smaller than 1.67 x element diameter d, there is a possibility that the asphalt pavement water cannot flow into the interior and thus may not play the role of the raceway device, and the pitch p is 2 x element diameter d Greater than), asphalt bitumen can penetrate into the pitch and obstruct the flow of permeate.

As described above, the package hydrographic apparatus 100 of the present invention has a shape of a spring in which the permeate can be smoothly guided into the apparatus as the main function of effectively draining the permeate and the residual water.

The water supply device 100 of the present invention is installed on both sides of the asphalt pavement 120, as shown in Figures 5 and 6 in the structure for constructing the asphalt pavement 120, such as roads and bridges (110). . This is used to guide rainwater (penetration) coming into the asphalt pavement 120 to the drain port 130 to discharge to the outside.

Such a raceway 100 has a coiled spring structure, in which water infiltration of the asphalt pavement 120 penetrates between the pitches p of the spring-type raceway 100, whereas the asphalt mixtures have a pitch ( Since particles are formed larger than P), the particles do not flow into the water supply device 100, and only the penetrated water is guided and discharged through the interior to the drain 130.

Accordingly, the present invention provides a gap in which the pitch (p) interval of the spring can be introduced into the water, and if the packaging material enters the interior of the faucet during construction due to such a void, the inside can be blocked and lose its function. The pores are large enough to prevent penetration of the packaging material. The pore size can be overcome by using a packaging material of any material because the pore size can be manufactured in various forms by adjusting the pitch (p) spacing of the spring.

In addition, since the structure to be buried in the package body should be able to maintain the shape to ensure the original function of the power unit against the external load such as the wheel load of the vehicle, in the present invention, the buckling strength through the appropriate thickness and cross-sectional diameter of the spring Will also secure. In addition, by utilizing the flexibility of the characteristics of the spring to ensure the ease of construction even if the bottom of the package is not smooth or curved.

As described above, according to the present invention, it is possible to effectively drain the infiltration water and the residual water permeating to the current pavement, and if the present invention is applied to the pavement of roads and bridges, the pavement is damaged and repaired by the infiltration water. In addition, the cost of assessing and repairing damage to bridge decks can be significantly reduced.
