Description

Drain for bridge

The present invention relates to a water collector for a bridge, and more particularly, to a water collector for a bridge that can be opened and closed with a foot so as to facilitate maintenance of hundreds of bridge water collectors installed on the bridge.

Generally, at the edge of the bridge supported by the pier, a water sump for collecting water flowing due to rain or snow is installed in a line.

1 is an exploded perspective view of a conventional water collector for a bridge. As shown, the conventional bridge water collecting device includes a water collecting head 1 embedded in the edge of a bridge slab, an extension pipe 2 extending from the bottom of the water collecting head 1 to the lower side, and the water collecting head 1 . A grating (3) with a plurality of grids (3a) installed to filter large foreign substances as coupled to the inlet, and a sieve (4) built in the water collecting head (1) to filter foreign substances contained in water that has passed through the grating (3) is composed of And the extension pipe (2) is connected to the drain pipe connected to the sewage facility on the lower side of the pier.

By such a water collecting port, the water flowing through the bridge slab is collected in the water collecting head 1 and then drained to the sewage facility through the extension pipe 2 and the drain pipe.

However, as foreign substances filtered through the sieve 4 accumulate, the hole formed in the sieve 4 is blocked, and soil and soil are gradually accumulated along with this. In this case, the water catchment cannot drain the water flowing from the bridge slab, and water accumulates on the surface of the bridge slab, which causes damage to the pavement of the bridge slab or deterioration of the bridge structure. Accordingly, the bridge manager repeats the maintenance work of regularly or irregularly opening the grating 3 , taking out the sieve 4 built in the water collection head 1 , and removing accumulated foreign substances or soil.

However, since the grating 4 is made of non-ferrous metal and is heavy, it is very difficult to separate the grating 3 from the numerous collection heads 1 installed in a row on the bridge. In particular, when earth and sand is caught between the water collecting head 1 and the grating 3, the grating 4 is tightly sandwiched in the water collecting head 1, so even if a tool such as a hook is used, the grating 3 was even more difficult to separate from the water collecting head (1).

In addition, when a lot of foreign substances and soil are accumulated in the sieve 3, the sieve 3 remains tightly fitted to the bottom of the water collection head 1, and the process of separating the sieve 3 from the water collection head 1 It was also very difficult.

And since the grating made of non-ferrous metal has a high unit price per unit weight, there is a problem that many gratings 4 are stolen every year.

The present invention was created to solve the above problems, and it is possible to easily open and close the grating using a foot without a separate tool, thereby enabling easy maintenance. An object of the present invention is to provide a water collecting device for a bridge.

Another object of the present invention is to provide a water collecting device for a bridge, which can easily separate a sieve to remove soil and foreign substances.

Another object of the present invention is to provide a water collecting device for a bridge, wherein the grating is not separated from the water collecting head to prevent theft.

And FIG. 7 is a view for explaining the operation of the water collector for a bridge of FIG. 2 .

As shown, the water collecting device for a bridge according to the present invention includes: a water collecting head 10 embedded in the edge of a bridge slab and having first hinge ends 11 formed on both edges of the inner side; an extension pipe 20 extending from the center of the bottom of the water collecting head 10 to the lower side; a grating 30 coupled to the inlet of the water collecting head 10 and having a second hinge end 31 hinged to the first hinge end 11; and a sieve 40 for filtering foreign substances contained in the water collected by the water collecting head 10 .

As shown in FIG. 3 , the water collecting head 10 has a hopper shape as a whole having a square inlet. The extension pipe 20 extends from the center of the bottom of the water collection head 10 to the lower side and is connected to a drain pipe (not shown) connected to the sewage facility on the lower side of the pier.

The sieve 40 has a basket shape in which a plurality of perforations 41 are formed, and filters foreign substances contained in the water collected by the water collecting head 10 through the grating 30 .

The grating 30 allows the water flowing along the bridge slab to be collected by the water collection head 10, and at the same time filters large foreign substances contained in the collected water, for example, wood chips, cans, bottles, etc. It has a structure in which a plurality of grids 32 are installed at regular intervals. The grating 30 opens or closes the inlet of the water collecting head 10 as the first and second hinge ends 11 and 31 are rotated about the axis.

Here, with respect to the second hinge end 31 , a portion rotated inside the water collecting head 10 is defined as a grating front part (A), and a portion rotating outwardly of the water collecting head 10 is defined as a grating rear part (B). ) is defined and explained.

In the present invention, any one of the first hinge end 11 formed on the water collecting head 10 and the second hinge end 31 formed on the grating 30 is a protrusion, and the first hinge formed on the water collecting head 10 . The other one of the second hinge end 31 formed on the end 11 and the grating 30 is a hole through which the protrusion is inserted. In the present embodiment, the first hinge end 11 is a protrusion protruding from the inner circumferential surface of the water collecting head 10 , and the second hinge end 31 is a hole formed in the side surface of the grating 30 . Also, of course, the first and second hinge ends 11 and 31 may be implemented by forming holes in the water collecting head 10 and the grating 30 and inserting pins into the holes.

Since the grating 30 is rotatably coupled to the water collecting head 10 by the first and second hinge ends 11 and 31 , the grating 30 cannot be separated from the water collecting head 10 , and accordingly It is possible to reduce the possibility of theft of the grating 30 .

As shown in FIGS. 3 and 5, on one side of the inner circumferential surface where the pair of first hinge ends 11 are not formed in the water collecting head 10, the first and second hinge ends 11 and 31 as the center A rotation groove 12 having an inner curvature corresponding to the circumference is formed. By forming such a rotation groove 12, when the grating 30 is rotated about the first and second hinge ends 11 and 31 as an axis, a space formed at the end of the front part (A) can move. to form

As shown in FIGS. 3 and 5 , on the inner circumferential surface of the water collecting head 10 opposite to the rotation groove 12 centered on the first hinge end 11 , a grating 30 is formed of the water collecting head 10 . When closing the entrance, the step 13 on which the rear portion (B) of the grating is mounted is formed. At this time, the step 13 is formed to protrude along the inner circumference of the water collecting head 10 from the rear side of the first hinge end 11, and widely supports the edge of the rear portion B of the second hinge end 31 of the grating. do. Since this step 13 supports the rear portion B of the grating 30 that is already supported by the first and second hinge ends 11 and 31, even if a large load is applied to the grating 30, the grating ( 30) can be prevented from being depressed into the water collecting head 10 .

The first and second hinge ends 11 and 31 formed on the water collecting head 10 and the grating 30, as shown in FIG. 4, when the length of the side of the grating 30 is defined as L, 1 /3L ~ 2/5 L position is biased. For example, if the side length of the grating is defined as 25 cm, it is in the range of about 8 cm to 10 cm.

Here, based on the second hinge end 31, the 1/3L ~ 2/5 L point becomes the front portion (A), and the remaining portion becomes the rear portion (B), the second hinge end 31 Since the asymmetrical bias, the load applied to the rear portion (B) with respect to the second hinge end 31 is greater than the load applied to the front portion (A). Accordingly, the grating 30 hinged to the first and second hinge ends 11 and 31 is in a state where the heavy rear portion B side is mounted on the step 13, and the grating 30 is the water collecting head. (10) remains closed.

When the grating 30 intends to open the water collecting head 10, as shown in FIG. 7, the front portion A side is gently pressed using a foot. Then, the front part A is immersed in the water collecting head 10 by the additional force attached to the front part A, and the rear part B is lifted.

Further supplementing, when the position where the first and second hinge ends 11 and 31 are formed is 1/3L or less from the side of the grating front part (A), for example, the end side of the grating front part (A) If it is located biased to, even if the space between the end of the grating front portion (A) and the first and second hinge ends (11, 31) is narrow, the space where the manager's feet are raised is not secured. In this case, it is impossible for the manager to rotate the grating 30 using his or her feet while standing up.

And when the first and second hinge ends 11 and 31 are biased by 2/5 or more from the side of the grating front A, for example, the first and second hinge ends 11 and 31 of the grating 30 are When positioned approximately in the center, the difference in load (weight) between the grating front portion (A) and the grating rear portion (B) becomes small. In this case, just by lightly pressing the grating front part (A), the grating 30 is rotated and the water collecting head 10 is opened. A case may occur, and a case in which the grating 30 is rotated in an unintended state by a falling object falling from the vehicle while driving may occur.

As such, in the present invention, by having the core technology in which the first and second hinge ends 11 and 31 are located in the range of 1/3L to 2/5 L biased toward the grating front part (A), the manager is separately You can rotate the grating 30 by pressing the front part of the grating (A) with your foot while standing without any tools, and the strainer can be replaced in this state, resulting in easy maintenance of hundreds of water catchments. will be.

On the end surface of the front portion A of the grating 30 , as shown in FIG. 5 , a grating sealing jaw 35 for filling the space formed by the inner curvature of the rotation groove 12 is installed. The grating sealing jaw 35 has an outer curvature corresponding to the inner curvature of the rotating groove 12 and is made of an elastic material. The grating sealing jaw 35 is inserted into the rotation groove 12 in a state in which the grating 30 closes the entrance of the water collecting head 10, in this case, the outer curvature formed in the sealing jaw 35 is the rotation groove 12. Minimizes the occurrence of a gap between the rotation groove 12 and the sealing jaw 35 by meshing with the inner curvature formed in the hardening is prevented. Accordingly, when the water collecting head 10 is to be opened for maintenance, the grating 30 can be smoothly rotated.

At both lower edges of the grating 30, as shown in FIG. 6, a pair of guide jaws 33 are formed, and at the upper end of the sieve 40, guide wings slidably coupled to the guide jaws 33 ( 43) is formed. At this time, the guide jaws 33 are formed between the first and second hinge ends 11 and 31 .

Since the sieve 40 is mounted on the guide jaw 33 of the grating 30 , it maintains a floating state inside the water collecting head 10 . Accordingly, accumulation of soil or foreign substances between the sieve 40 and the bottom of the water collection head 10 is prevented.

On the other hand, on the upper surface of the guide blade 43, as shown in FIG. 6, the wing sealing jaw 45 made of an elastic material to fill the gap space formed between the guide jaw 33 and the guide blade 43. ) is installed. The wing sealing jaw 45 minimizes the occurrence of a gap between the guide blade 43 and the grating 30 on the inside of the guide jaw 33 so that earth or foreign substances are trapped between the guide blade 43 and the lower surface of the grating 30 . Prevents from over-accumulating and hardening. Accordingly, when you want to remove the soil or foreign substances accumulated on the inside of the sieve 40, it can be gently pulled out from the grating 30 and separated.

On the upper side of the sieve 40, when a lot of water is collected by the water collection head 10 due to heavy rain and the flow rate exceeds the flow rate that the perforation 41 of the sieve can pass, a bypass hole 47 for draining water immediately. this is formed By the bypass hole 47, water can be effectively drained even when the flow rate suddenly increases.

Here, the bypass hole 47, as shown in FIGS. 3 and 7, is formed to be biased to one side from the upper portion of the sieve 40. Accordingly, when the grating 40 is rotated to separate the sieve 40 from the grating 40 in the obliquely positioned state, it is possible to minimize the foreign matter accommodated in the sieve 40 from escaping to the outside.

Next, the operation of the water collector for a bridge of the present invention will be described.

When trying to separate the sieve 40 supported by the guide jaw 33 of the grating 30 from the water collection head 10 in order to maintain the water catchment buried in hundreds of units along the bridge slab, the manager stood up In this state, gently press the grating front part (A) with your feet. Then, the grating front part (A) is immersed into the water collecting head (10) and the grating rear part (B) is lifted so that the grating 30 opens the water collecting head (10), and in this state, hold the sieve (40) When pulled, it can be separated from the guide jaws 33 of the grating 30 and recovered.

That is, since the operation of opening the water collecting head 10 can be performed by gently pressing the grating front part A using the foot, it is possible to quickly and easily replace the sieve from the water collecting unit of hundreds of units installed along the bridge. , furthermore, the collection of large foreign substances collected inside the water collecting head 10 can also be carried out easily.

As described above, according to the present invention, since the grating 30 is rotatably coupled to the water collecting head 10 by the first and second hinge ends 11 and 31, a foot is used without using a separate tool. The water collecting head 10 can be easily opened or closed by rotating it easily. Accordingly, it is possible to easily maintain the hundreds of water catchments installed on the bridge.

In addition, since the grating 30 has a structure coupled by the first and second hinge ends 11 and 31 , the grating 30 cannot be separated from the water collection head 10, and accordingly, the grating 30 is stolen. can reduce the likelihood.

And, since the sieve 40 is a slidingly coupled structure to the grating 30, it is possible to facilitate the separation and coupling of the sieve 40 in a state in which the grating 30 is rotated, and thus the maintenance of the bridge is even easier. is possible
