Description

[0001] The present invention relates to a two-

The present invention relates to a method of manufacturing a composite pipe which is capable of adjusting the height of a slab (for example, a height of a slab) depending on a state of a bridge, The height of the two-stage height adjustment receptacle.

Conventionally known bridge catches for lengths are known, for example, as disclosed in Patent Document (Korean Utility Model Registration Utility Model No. 20-0450900).

As shown in FIG. 6, a diaphragm 15, which is shaped to prevent foreign matter such as wastes from entering the inside, is seated on the upper part of the catching hole 10 having a square shape at the upper part and a cylindrical shape at the lower part thereof And a joint pipe 30 is connected to the lower part of the catch 10.

In particular, a cylindrical auxiliary housing 13 for supporting and supporting the outer wall is provided in the water collecting receptacle 10 so as to be vertically movable. At the upper end thereof, a fixing bolt (not shown) for fixing the water receptacle 10 to the outer wall surface And a flange portion 16 having a piece hole 17 for fixing the mold 40 to the mold 40 is integrally formed at the lower end thereof.

In addition, a ring-shaped catching protrusion 11 is formed to protrude along the circumference of the outer wall of the catching hole 10 so that the fixing bolt 14 is caught during the downward flow of the auxiliary housing 13, Respectively.

A connection pin 12 for connecting the joint pipe 30 is formed at a position symmetrical to the joint pipe 30 at the lower end of the water collecting port 10. A guide hole 31 is formed in the upper end of the joint pipe 30, Respectively.

The catch of the Patent Document 1 has the following problems.

The concrete to be poured penetrates between the auxiliary housing 13 and the catch and falls downward.

Since the length of the auxiliary housing 13 is adjusted only by the bolts 14, the flange portion 16 for the piece hole 17 must be formed in order to prevent the auxiliary housing 13 from moving when the concrete is poured.

Since the catching jaws 11 to which the bolts 14 are caught must be welded around the catching ports, the welding flux must be wide.

In addition, a fallen leaf or the like, which has entered through the diaphragm 15, can be clogged in the catching pipe, the joint pipe, and the connecting drain pipe.

In addition, since the joint pipe 30 has the structure in which the connection pin 12 is engaged with the guide hole 31, the joint pipe 30 exposed to the outside of the poured concrete may be shaken by the wind or the like to be noisy or detached.

On the other hand, as shown in FIG. 7, there is a filter part 130 inside the catching hole of the patent document (Korean Utility Model No. 20-0446850), so that only the inflowed water is drained and debris such as fallen leaves is caught.

Accordingly, in order to clean the foreign substances accumulated in the filter unit 130, the grating unit 120 is opened and the filter unit 130 is lifted.

However, since these collecting ports are installed on both sides of 5 m each, if the length of the bridge is 200 mm, the opening of the grating portion 120 and the retraction and insertion of the filter portion 130 incur a great time and cost do.
