The present invention relates to a bridge drainage device, and more particularly, to a bridge drainage device which facilitates a joint operation of a collecting pipe and a drain connection pipe embedded in a bridge slab, and enables height adjustment of the drain connection pipe. .

In general, a bridge is a structure such as an overpass or a bridge constructed over a river.

These bridges are composed of alternating bridges and bridges, and upper structures consisting of girders and top plates installed across the upper portions thereof, and the upper structures are supported and fixed as bridge devices installed on the upper sides of the bridges, and are then applied to the upper structures after construction. It is installed to enable expansion or contraction action according to the elastic stress.

Such bridges are equipped with drainage systems for drainage of sewage and rainwater. The bridge drainage system is composed of a collecting pipe for collecting sewage and rainwater flowing through the bridge top plate and a drain pipe for draining the sewage and rainwater collected by the collecting pipe to the lower part of the bridge.

As shown in FIG. 1, the conventional water collecting pipe 1 for a bridge drainage system is designed to protrude to the bottom of a concrete bridge slab 3 in order to connect with a drain 2 to be connected to a lower end as a tubular shape.

Therefore, since the water collecting hole through hole 4a must be drilled in the formwork 4 at the bottom of the bridge slab 3 at each position of the drain hole 2 of the bridge slab 3 where concrete is poured, the drain hole 2 for each span of the bridge slab 3 ) Installation location is different. Therefore, once the die 4, which has a water collecting through-hole 4a, cannot be recycled, the available resources must be discarded, resulting in economic loss and delayed construction period. In addition, since the hole is drilled in the formwork (4) of the bottom of the bridge slab (3), the work becomes difficult, and of course, the work is difficult, as well as the drilling work is in a dangerous environment, the worker's safety is impaired When concrete is poured, leakage of cement occurs due to the water collecting hole through hole 4a at the bottom of the bridge slab 3, thereby causing environmental pollution. In addition, since the protrusions projecting inwardly are formed in the water collecting port 1 for the coupling of the water collecting port 1 and the drain 2, there is a problem in that the waste is caught in the protrusions projecting inwardly of the water collecting port 1 and the drainage becomes poor.

In order to solve such a problem, there has been proposed a socket-type catchment structure for bridge drainage as a registered utility model No. 414770.

The conventional technique is a water collecting structure for bridge drainage, the upper portion is composed of the rainwater suction portion of the large diameter in which the water on the bridge is sucked and the rainwater discharge portion of the small diameter in which the suctioned water is discharged, and the lower end of the rainwater discharge portion is the bridge body A funnel-shaped catchment main body disposed so as not to protrude from the bottom surface of the catchment body, and the drainage insertion space is formed so as to form a drainage insertion space spaced apart from the rainwater discharge portion of the catchment water discharge body at a predetermined interval, and fixed to protrude into the inner drainage insertion space in the middle It is composed of a socket portion formed with a protrusion, and a drain hole is inserted into the drain hole insertion space between the rainwater discharge portion and the socket portion and the slit fixing groove is formed in the upper portion is passed through the fixed protrusion.

According to the prior art, since it is possible to form bridges by pouring concrete in a state that does not need to punch the formwork, even if the formwork is demolished after the concrete is cured, the formwork is not damaged and thus can be used again. Since the formwork is not perforated, the concrete does not leak, so the quality of the structure does not occur, so the quality of the structure is increased and the environmental pollution caused by the concrete leakage is prevented and the rainwater is discharged inside the rainwater discharge part. There is no protruding part, so drainage is good.

However, according to the water collecting structure for bridge drainage according to the prior art, it is necessary to turn the entire drain to be inserted into the catch, which is very difficult and cumbersome because the weight of the drain is heavy and the length is long. In addition, when the drain is straight, it has only the above-described problems. However, when the drain is elbow type, it may be difficult to match another drain pipe to be connected to the outlet side of the drain.

In addition, although the connection position of the drain and the drain pipe may vary depending on the surrounding structure, there is a problem in that the height of the drain can not be adjusted because only one coupling position of the drain is formed. There is also a problem.

An object of the present invention is to provide a bridge drainage device for facilitating a connection work between a collecting box and a drain connection pipe embedded in a bridge slab.

In addition, an object of the present invention is to connect the control of the height of the drain connection pipe freely.

Bridge drainage device according to the present invention for achieving the above object is characterized in that it comprises a socket coupled to the upper portion of the drain connection pipe and fixed to the collection box buried in the bridge slab.

A fixing bolt is formed in the collecting box, and the socket is provided with a fixing groove to which the fixing bolt is fixed to be adjustable in height.
