Abstract

PURPOSE:To enable safe and easy installation of a door body, by a method wherein a gate door body having a water tank is caused to float on a water surface, and after the door body is caused to stand upright through pouring of water, the door body is towed to a dam, and it is lifted up with the aid of a winder on a pier to install it. CONSTITUTION:A gate door body 2 is caused to float on a water surface, water is poured in each of water tanks 3-6 through a water feed and discharge pipe 7 to bring the door body 2 into a standing-upright state, and the door body is brought to a given draft condition. After the door body 2 is towed to an estuary weir 1 by means of a tug-boat, the door body 2 is turned in a 90 deg. arc to position it between piers 10. A wire rope 15 suspended from a winder 11 is wound around a pulley 14 mounted in a mounting hole, with the winder 11 being operated, the rope 15 is wound to hoist the door body 2, and water in the water tanks 3-6 is drained. Further, after components, such as a side water tight rubber, a flow uniformizing plate, are mounted in a hoisted condition, the door body 2 is lowered for installation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for transporting and installing a gate body.

The structure of the conventional example and the method of transportation and installation of the gate body were
There is No. 12493. According to this, the gate door body (1) is laid down and fixed on the barge (2), the barge (2) is sailed to the river mouth weir, and the gate door body (1) is hoisted by a hoist on the pier. After being erected, it is pulled upwards and installed.

With such a conventional configuration, the gate door body (riga barge (5)
Since it is placed on top of the bridge, it may be too bulky to pass under the bridge. In this case, the gate body (1) is lifted by a crane on the bridge and moved over the Ja beam. etc., which requires time and effort to transport. Furthermore, during installation, the lying gate body (1) must be raised up, and at this time, the palannu of the barge is likely to collapse, posing a safety problem.

Purpose of the Invention The present invention provides a method for transporting and transporting a gate body that eliminates the above-mentioned conventional drawbacks.
The purpose is to provide installation methods.

Structure of the Invention In order to achieve the above object, the gate body of the present invention is transported and
According to the installation method, a watertight gate body having a water tank is floated on the water surface, water is appropriately injected into the water tank to bring the gate body into an upright state, and the water is made to stutter in a predetermined manner. Next, the gate body is towed or self-propelled to a predetermined dam or weir, and then the gate body is lifted and installed by a hoist on the via.

Embodiment and Function An embodiment of the present invention will be described below with reference to the drawings. This embodiment relates to the case where a gate body (2) is installed on an estuary weir (1), and water tanks (3) to (6) are provided near the four corners of the gate body (2). (7) (8) indicates the water supply and drainage pipes and air vent pipes that run from the top of the gate body (2) to each water tank (3) to (6), and (9) indicates each water tank (
3) to (6) are drain valves attached to the bottom surface. u
O is the via of the river mouth weir (1), and a hoisting machine (u+) is installed above it. (2) is a bridge spanning between the via bends, α4 is a hole in which the pulley U4 formed at both ends of the upper part of the gate body (21) is housed.

The transportation and installation method of the gate body (2) will be explained based on the above configuration. First, the gate body (2) is floated on the water surface, and water is appropriately injected into each water tank (3) to (6) from the water supply and drainage pipe (7), and the gate body (2) is brought into an upright state. Bring the stuttering to the specified state. Next, the gate body (2) is towed to the estuary weir (1) by a tugboat (an outboard motor may be attached to the gate body (2) to allow it to propel itself).

If it is necessary to pass under a bridge on the way, water can be injected into each of the water tanks (3) to (6) from the water supply and drainage pipe (7) to reduce the stifling water. Next, as shown in FIG. 3, the gate body (2) is rotated by 15 degrees and positioned between the piers QCj. Next, store the pulley a4 in the utility hole (13), wind the wire rope hanging from the hoist αυ on the pulley side, operate the hoist <11), and wind the wire rope u5. Hoist the gate body (2). Also, at this time, open the water drain valve (9) and open each water tank (3) to
(6) Drain the water inside. Next, parts such as side watertight rubber and rectifier plates are attached while the unit is lifted.

Next, the gate body (2) may be lowered and installed.

Effects of the Invention As mentioned above, according to the invention, the gate body itself is floated and towed or self-propelled, so there is no need for a conventional barge, and there is no need to pass under the beam. When this is not possible, water is injected into the water tank to lower the stuttering of the gate body, allowing the gate to pass under the bridge easily. Furthermore, the gate body has an upright shape 4
Some items are brought to the dam or weir in step 6, so they can be lifted and installed in that state, which is highly safe.
