Description

The present invention is rectangle culvert, a mobile water stop wall available for all rectangles Hirakimizo.

Conventionally, when water and sewage pipelines are damaged due to earthquakes, disasters, accidents, etc., construction has been carried out without stopping the running water and sewage for restoration work on damaged parts or replacement of old pipelines.
There is known a water channel opening and closing device that can make the working area of a water recovery part of a BOX type, a circular type, an egg type, or a horseshoe type in an open channel or a culvert channel with always flowing water (see Patent Document 1). ).
In this known technique, a main body fixing jig having water-stopping rubber on two surfaces having the same vertical shape and a L-shaped cross section as the vertical wall surface portion of a water channel with constantly flowing water is installed and fixed on both sides of the water channel wall surface with jig fixing hardware. The water channel opening / closing device with water stop rubber on the upper and lower sides is combined with the metal fittings for the two main body fixing jigs installed and fixed on both sides of the water channel wall, so that the inside of the water channel can be opened and closed with the body fixing jig. This is a water channel opening / closing device that is shielded by the device main body, and that allows the flowing water in the large water channel to be temporarily dammed or flowed by the pressure-acting opening / closing heavy pressure-resistant lid of the water channel opening / closing device.

  Then, install a ceiling hoist traveling beam for the overhead traveling hoist on the ceiling part inside the existing water channel to be restored up to the range where the water channel switching device main body is installed, and a heavy body fixing jig, water channel switching device main body and connection A ceiling hoist for horizontally moving and assembling and installing cylindrical tubes is attached to the ceiling hoist traveling beam, and the overhead traveling hoist is used to move the body fixing jig, which is a heavy object, and the water channel switch body to a predetermined position. It is.

  In this way, the ceiling hoist traveling beam for the overhead traveling hoist must be installed in the ceiling part inside the existing water channel to be restored up to the range where the main body of the water channel opening and closing device is installed. Therefore, there has been a demand for a water stop wall that can be easily moved to the work area.

  The water stop wall for movement of the present invention includes a rectangular water stop wall main body, a U-shaped slide auxiliary wall provided on both side surfaces of the water stop wall main body so as to be laterally movable, and the water stop wall main body. Since a pair of moving tires are detachably mounted on the left and right sides of the lower part, the water blocking wall body is moved with the moving tires, so that it is easy to move to the work area and the overall structure is simplified, There is an effect that the usability of the water wall body can be improved.

It is a front view of the water stop wall for movement of the present invention. It is a top view of the water stop wall for movement of the present invention. It is a front view of the state which equipped with the tire for movement to the water stop wall for movement of the present invention. It is a right view of the state which attached the tire for movement to the water stop wall for movement of the present invention.

One embodiment of the water blocking wall for movement of the present invention will be described below with reference to the accompanying drawings.
As shown in the front view of FIG. 1 and the plan view of FIG. 2, the water stop wall for movement of the present invention is provided in a rectangular water stop wall body 1 and on both side surfaces of the water stop wall body 1 so as to be movable left and right. A pair of moving tires 3 on the left and right sides of the lower part of the water blocking wall body 1 as shown in FIG. 3 and the right side view of FIG. , 3 are detachably equipped.

  The water blocking wall body 1 is formed with a circular through hole 4 at the center lower portion, and a short cylindrical temporary drain pipe 5 is fixed to the circular through hole 4 so as to protrude forward. Further, steel parts 7, 7, 7, 7 for installing a main jack are provided at the four front corners of the water blocking wall body 1. As shown in FIG. 2, the steel parts 7, 7, 7, 7 for installing the main jack have triangular reinforcing members 8, 8, 8 fixed to the inner sides facing left and right, and the outer side is a flat surface 9.

The slide auxiliary wall 2 has a U-shaped cross section that matches the cross section of the side wall of the water channel, and the opening side is positioned on the water stop wall body 1 and the water stop is on the inner side located on the back side of the water stop wall body 1. A packing 10 is provided, and a number of member crimping bolts 11 are provided on the outer side located on the front side of the water blocking wall main body 1 at approximately equal intervals.
Further, on the front side on the closed side, there are provided sub jack-installing steel parts 12, 12, 12, 12 for installing the expansion jack 6 at positions facing the above-described main jack-installing steel parts 7, 7, 7, 7. .
As shown in FIG. 2, the sub-jack installing steel parts 12, 12, 12, 12 have triangular reinforcing members 13, 13, 13 fixed to the outer sides facing left and right, and the outer side is a flat surface 14.

As shown in the front view of FIG. 3, a temporary drain pipe 5 is provided on the right and left sides of the lower part of the water stop wall body 1 so that the moving tire 3 can move the water stop wall body 1 back and forth along the water channel. the right and left, detachably attached by a bolt 15 through transmural the waterproofing wall body 1 shown in FIG. 4 the support member for supporting both ends of the axle portion of the moving tire 3.
