Abstract

The present invention provides a steel pipe for a barrier wall to enable selective steel pipe spacing and to completely shield water. The steel pipe for a barrier wall comprises: a pair of steel pipes connected together by a connector such as an H-beam to be applied with a linear slit for coupling cut-off plates in the longitudinal direction of a steel pipe on the main wall opposed to the connector; and a cut-off plate with no width limit to be engaged with and block the slit of the steel pipe and the slit of another steel pipe adjacently installed to the steel pipe. A waterproof sheet is attached to a soft portion of the slit on the inner circumference of the steel pipe and to the back plate of a catching piece coming in contact with the soft portion, thereby improving water shielding performance.

Description

STEEL PIPE FOR WATERTIGHT WALL

The present invention relates to a steel pipe for use in constructing a main-drive-type water-supply wall by connecting two steel pipes laterally so as to select an installation interval with another steel pipe adjacent to the steel pipe and to strengthen the water- .

Generally, according to the design of the structure in the soft ground, the terra incinerator constructs the main thermal type earth wall which supports the untreated land and the adjacent land on the boundary line so that the soil can not be collapsed. It is also possible to build up the earth wall by tying steel pipes at the boundary of excavation piles prior to the trenching. The steel pipe for the aft wall seals the joint between the steel pipe and the steel pipe so that the inflow of the ground water is blocked.

Since the steel pipes of Patent Documents No. 2011-88326 and No. 1202182, which are constructed so as to form the water wall by fitting the male and female connection members to the opposite points on the outer circumferential surface of the steel pipe in one direction, Can not be selected. In the case of patent No. 813910, it is possible to construct the connecting members attached in the radial direction of the steel pipe to have a predetermined width so that the steel pipes do not come into contact with each other. However, since the product is a standardized product, Can not adapt to. In the steel pipe of Patent No. 1066612, only the female connecting portions are attached to the opposite points on the outer circumferential surface of the steel pipe, and the adjacent steel pipes are connected to each other at both ends in the width direction by a steel plate having male connecting portions corresponding to the female connecting portions. This prior art can not be made narrower or wider because it is impossible to change the dimension at the construction site since the steel plate is a design product. In any of the above prior arts, a gap is inevitably left in the steel pipe connection portion, so that it is difficult to expect an order.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a steel pipe for a water-wall which can select an interval of a plurality of steel pipes used for constructing main-drive-type water supply walls.

Another object of the present invention is to provide a steel pipe for a water-wall which has improved the technical structure for the degree of the joint between the steel pipe and the connecting material, thereby enhancing water flowability.

According to a first aspect of the present invention, there is provided a steel pipe having a pair of steel pipes connected to each other by a connecting member such as an H-shaped steel pipe and having a straight slit attached to a peripheral wall opposite to a connecting portion of the steel pipe, A slit of the steel pipe and a slit of another steel pipe adjacent to the steel pipe, which is a steel pipe for a water wall made up of a steel plate having no limit on the width.

A second object of the present invention is to provide a steel pipe for a water-wall with an improved water repellency by attaching a waterproof sheet to a slit portion on the inner circumferential surface of the steel pipe and a back plate of the engaging member abutting against the slit portion.

The present invention is characterized in that the steel plate is excellent in making and is not affected by the width of the steel plate, unlike the steel plate having the steel plate connecting portion and the male and female connecting portions, so that the width of the steel plate can be freely selected So that the construction quality of the water supply wall is improved. In the case of selecting a wide-width steel plate, especially steel pipe reduction effect can be seen.

In addition, since the connection between the steel pipe and the steel plate is complemented by a waterproof sheet, the order reliability of the steel pipe and the steel wall constructed with the steel plate is high.

Fig. 1 is a perspective view showing a steel pipe and a steel plate according to the present invention,
Fig. 2 is a state diagram of the steel pipe and the water-
3 is a plan view of a steel pipe connected and assembled with the present invention plate
4 is an enlarged view of a connection portion between a steel pipe and a water-
Fig. 5 is an enlarged view of the steel pipe and the degree reinforcing portion of the steel plate connecting portion according to the present invention.

As shown in FIG. 1, the steel pipe 10 is a pair of two, and the parts facing each other in parallel are integrated by the connecting member 11, as shown in FIG. The connecting material (11) is to be selected from among the H-sections that are in the market in consideration of the strength of the joint, maintenance, preparation, cost and cost.

In the steel pipe 10, a slit 12 is formed in a pipe wall on the opposite side of the connecting member 11. The slit 12 should be formed at the upper end of the steel pipe 10 in consideration of the fact that the steel plate is fitted on the upper side of the steel pipe 10, The steel pipe (10) is designed to be much longer than the excavation depth, so that even if the ground is excavated up to the design depth, it is deeply embedded so as not to be exposed at all, It is necessary to form the slit 12 at least so as not to penetrate the lower end of the steel pipe 10 in order to equalize the depth to which the steel plate is inserted without spreading.

The water level plate 20 is made of a steel plate, and the width is determined in consideration of the condition (strength) of the ground where the water level wall is to be constructed. At both ends in the width direction of the support plate 20, a latching piece 21 is attached over the entire length thereof. The engaging pieces 21 are formed on both sides of the inner circumferential surface of the soft steel pipe 10 at the inner end of the slit 12 when the diaphragm 20 is fitted into the slit 12 facing the adjacent steel pipe 10 The steel pipe 10 hangs and maintains the gap between the steel pipe 10 and the steel pipe 10, thereby stabilizing the posture, thereby faithfully fulfilling the function as a connection member.

In order to increase the adhesion of the curved surface to the inner circumferential surface of the steel pipe 10 and to improve the degree, the engaging pieces 21 are welded to the widthwise ends of the steel plate 20 to be integrated.

Fig. 2, Fig. 3, and Fig. 5 show a state in which two sets of steel pipes 10 and 10 are arranged side by side along the main heat direction, and the steel plates 10 and 10 are assembled by fitting the steel plate 20 to the slits 12 and 12 facing each other Bar, in this case, the case in which the engaging plate 21 is engaged with the vertical pipe so as to be caught inside the steel pipes 10, 10. Continuously, the steel pipe 10 is formed in accordance with the above-described manner, and the steel plate 20 is combined with the steel plate 10 every time. The width of the water level plate 20 is adjusted to the installation interval of the steel pipes 10 and 10 considering the site conditions.

The waterproof sheets 30 and 31 having elasticity and perfect watertightness at the inner end of the slender pipe 12 and at the inner circumferential surface of the soft steel pipe 10 and the back plate 22 of the retaining piece 21, The side waterproof sheets 30 and 31 are elastically brought into close contact with each other when the waterproof sheet 20 is inserted into the slit 12 of the steel pipe 10 to eliminate the gap, Increase the reliability of the water wall by adding the water repellency.
