JPS6047109A - Repairing of packing of dry-dock flap-gate - Google Patents

Abstract

PURPOSE:To make the exchange of packings easier by a method in which a float is attached to the upper part of a flap-gate, the fitting pins at the lower part of the water gate are drawn out, and the water gate is horizontally floated by tensing a wire and also by the discharge of the lower water-immersed tank. CONSTITUTION:In repairing a flap gate for a dry dock, etc., a float 13 is attached to the upper part of the water gate 1, pins 3 connecting the hinge piece 2 with the fitting piece 5 of the water gate are drawn out, and the water gate 1 is pulled by a wire 15 to an erectly inclined floating state. By pulling a wire 14 attached to the lower end of the water gate 1, the water gate 1 is made horizontal, and an underwater drain pump 16 is put into the lower water-immersed tank 10 to drain the sea water. Since the water gate 1 can float horizontally by itself, the repairing and exchange of packings 8 can be easily made.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of repairing a punkin in a sluice gate such as a seven-ramp date used in dry docks.

The water gates installed in dry tonks for repairing ships are as shown in Figures 1 to 3. Figure 1 is a vertical cross-sectional view of the gate, and Figure 2 is the left half of the tank, showing the inside of the tonk. Front view showing the water gate seen from the ocean side at right Ube, No. 3
The figure is a plan view of a water gate, and the water gate J is a water gate installed on an underwater foundation 11V7%W4 through a pin 3 with a hinge piece 2 stepped up in multiple stages at its base end. It is pivoted to the old nape piece 5 and can be raised and lowered.

Generally, a buoyancy tank 9 is provided in the center of the water gate 1 in order to make it easier to stand up. In the lower part of the buoyancy tank 9, algebraic sections having an opening 10a on the dock 6 side are provided, and these sections are connected to the submersion tank 1.
It is 0.

Note that the reference numeral 11 indicates a handrail, and the reference numeral 12 indicates a bulwark.

As shown in FIG.
In order to prevent seawater from entering the pack 6 at that time, a seal 8 is installed at the part where the water gate J is secured to the beam wall 7.

This Pachinko 8 is made of wood and has a long history of wear and tear, and requires replacement and repair once every 5 to 6 years. Gate 1
After removing the buoyancy tank from the foundation structure 4, it may be hoisted up by a crane at sea and repaired on land, or the buoyancy tank may be removed.
It was used to float the ship and put it in the dock (for the 11th burial).

However, with this conventional packing method, when lifting the water gate with a crane, it is necessary to reinforce the water gate so that it does not break under its own weight.
Fix it by storing it in Pyri]! I! When doing so, it is necessary to tow the pond and drag the water gate to the tonk.
'1. The problem is that the repair work is time consuming and costly, as it requires the construction of a board for the water gate.

The present invention attempts to solve these problems by providing buoyancy to the water gate, exposing part of its pankin above the sea surface to water, The purpose is to provide a method for repairing the sluice gate door 1) I3 way so that you can repair the sluice gate door.

For this reason, the method for repairing a water gate puncture according to the present invention is to install a floating body on the top of the water gate when repairing a water gate gasket whose base end is pinned on the submerged foundation structure and has a submergence tank at the bottom. By removing the bottle and keeping the water gate in an upright floating state, pull up the lower end of the water gate to grasp the water tank and fill it with water. While keeping the water almost suspended in water γ, expose t = 1 part of the seal at the water gate to the water surface, and then repair the seal at 9, +f.
It is a sign.

The method of repairing the gasket of a water gate door as an embodiment of the present invention will be explained below with reference to the drawings. 1 is the side view showing the state in which the water gate is released from the underwater structure.
．． Sixth, the floating state of the water gate in the sea, Yasu 1lt
Figure 7 is a side view showing the lower part of the water gate being lifted by a crane, and Figure 8 is a side view showing the condition of the water tank being drained. Figure 8 is a side view showing the state of repair of the water gate. 9-1 is a view taken along the 1x-l'X arrow in FIG.

First, the floating body 13 is placed on top of the water gate 1 with the water gate 1 standing upright. In this embodiment, a general 7 Engu is used as the floating body 13, and three of them are tied to each end of the water gate 1 in the longitudinal direction, making a total of six 7 Engu or floating I+13 (No. (See Figure 9).

Next, remove the pin 3 that connected the hinge piece 2 and the water gate mounting piece 5 (see No. 5 and 1), and
and keep it in an upright floating state (see Figure 6).
.

At this time, in order to facilitate the transition to the floating state shown in Fig. 6, after removing the pin 3, the hanging wire 15, one end of which was tied to one or two sides of the water gate 1, was pulled with a land crane. (1+) Then, as shown in Figure 7, by pulling the suspension wire 14 with one end attached to the lower end of the water gate 1 using a land crane, the water gate is constructed by T-work. Keep the horizontal state 1 and position the 1illD 10a of the immersion tank 10 above the sea surface, then put the water pump 1 into the immersion tank 10 where the water gate is 1:1, and open the immersion tank. 11) Drain the seawater inside.

11 The flooded tank 10 gives buoyancy to the flood gate 1. In this embodiment, out of the 14 flood tanks 10, 1 degree flood tanks selected in the longitudinal direction of the flood gate 1 are used. 1(), the water gate 1 will be in the state shown in FIG. 8.

In other words, it floats horizontally with its own blade and brings 8 to the sea surface.
After that, it will be exposed to the sea, and it will be possible to repair and store the pa-nokin 8, so it will be exposed to the sea.
<7Kin8 I1τ principle.

After the repair is completed, water is poured into the flood tank 10 and the water gate door 1 is closed.
Lower the lower part of the , climb up to pin 3 and close the floodgate door 1! 11
゜Connect to foundation structure = 1.

Note that the number of floating bodies 13 attached to the top surface of the water gate 1 and the number of submersion tanks 10 for submerging water can be determined roughly (in this example, there are six floating bodies 13,
There is one submersion tank 10 for draining water, and it is possible to change it as appropriate depending on the floating state of the water gate during work.

] By two-way method, the sluice gate] can be opened by a marine crane (
Without using 9i, you can float horizontally to the sea surface with your own blade and expose Puffkin 8 to the sea surface. Repairs can now be made.

As detailed above, according to the method of repairing the seal of a water gate according to the present invention, by attaching a floating body to the second part of the water gate and removing the pin, the second water gate can be maintained in an upright floating state. After that, pull up the lower end of the water gate and pour water into the water tank as described in 2 above to keep the water gate in a horizontal floating state while attaching the gasket to the water gate. Installation f: A simple method of exposing the J part above the water surface and then repairing the above-mentioned gasket, it is possible to remove it from the dock or the sea.
1- It becomes possible to repair pangin at sea without using a crane, which has the advantage of simplifying repair work and significantly reducing repair costs.
