Abstract

<P>PROBLEM TO BE SOLVED: To improve a present situation of a turret-type tsunami-wave refuge facility installed on the street near the beech in which it is necessary to go up the narrow and steep stairs and single-person refuge is forced except for extremely physically strong persons, into a simple refuge method just like getting on a ferryboat. <P>SOLUTION: A tsunami-wave refuge boat is provided into which a person only needs to take refuge along a flat or a gentle slope, and which floats up at a present location, moves over a tsunami-wave of a designed height, is immune to repeated tsunami-wave, and also deals with the purpose of being besieged in accordance with the storage of emergency goods. <P>COPYRIGHT: (C)2013,JPO&amp;INPIT

Description

The present invention relates to a tsunami evacuation facility that can be used for meetinghouses and stockpiling warehouses, etc., during ordinary times, escape to the facility in the event of a tsunami emergency, escape from difficulty, and allow for a castle for several days while surpassing rain dew .

The tsunami evacuation site, where evacuation to a point beyond the tsunami's ultimate wave height is an absolute requirement, is sometimes far and steep, and in some cases it was essential to run up the stairs.

Problems to be solved by the invention

Most of the eaves-type evacuation facilities installed in the vicinity of the residential area require the action of running up stairs, so it can be said that it can be said that it is a severe selection place where physical ability and survival rate are in a proportional relationship. It was.

Means for solving the problem

The center of the float 1 has a flat circular shape with a large buoyancy that can be obtained regardless of the direction of water flow, and a bulging shape that gradually expands toward the bottom, and a flat upper deck that seals the bottom. A well-shaped hollow portion is provided.

A living space 2 with a roof 3 is integrally constructed on the deck of the float 1 so that it can be equipped and stocked to withstand the gathering during peacetime and the castle during evacuation.

The cylindrical pillar 4 that slides from the float 1 through the living space 2 and the roof 3 and the sliding core pillar 4 endure the horizontal force of the tsunami.

The core column 4 that allows vertical floating of the floating body while withstanding the horizontal force of tsunami and drifting object crashes is built with sufficient root in the solid ground

The core column 4 is a rectangle with a floating body that does not rotate or a cylinder having a spline mechanism.

The core column 4 that is well above the assumed height of the tsunami has a pulley 5 provided with a suspended weight 6 on the upper part of the core column that is close to canceling the weight of the floating body to which the load of the equipment and stockpile is applied. To increase the payload.

During normal times, a pit 7 in a dry environment is dug, which has a shape that matches the bulk of the float 1 and smoothly guides the tsunami water flow to the bottom of the float 1.

A pit 7 having a depth that can match the floor of the living space 2 and the level of the surrounding ground is dug to achieve direct escape.

When level matching is difficult due to site restrictions, escape by the slope pier 8 is attempted.

Effect of the invention

In an environment where the bulk of the float 1 matches the depth of the pit 7, it is possible to escape with perfect barrier-free.

Even if the level difference is not complete, evacuation by gentle slope slope climbing is not impossible by evacuating with a baby carriage, wheelchair, or stretcher by suppressing the slope, and it is possible to escape quickly with little assistance .

The location of the escape entrance, the number of locations, and the size of the frontage can be set freely, and many escapes can be made in a short time.

After the escape, the tsunami water lifts the float 1 and the living space 2 is never submerged as long as the core pillar has a margin.

This evacuation boat, which can be attached to walls and roofs, offers a safe and good prognosis compared to open-air shelters.

The predicted height of the corresponding tsunami and the degree of freedom in setting the number of capacities are extremely high, and it can be deployed from families to mega floats.

It is an elevation view of the present invention. It is a plane surface of the present invention.

BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will be described below.
(A) The float 1 receives the horizontal force of the turbulent tsunami water and selects the bottom shape that efficiently converts it to buoyancy.
(B) The planar shape of the float 1 is preferably a circular shape or the like that has few irregularities with respect to the core column and that is symmetrical and suppresses the generation of rotational force.
(C) The draft of the float 1 imposes a compromise between the required buoyancy and the escape height, and is designed taking into account the total weight of the entire floating body, the required buoyancy, and the payload.
(D) While the float 1 is intended to be lightweight, in order to avoid damage due to the impact of drifting objects, the strength and installation of barrier facilities are taken into consideration.
(E) The core column 4 prevents the locking of the sliding system due to the buoyancy of the float 1 and the uneven distribution of the load, and one central shaft that can easily maintain the smoothness of sliding even in a situation where a slight inclination variation has occurred. However, the rigidity of the base commensurate with the root effect of the pit 4 is ensured.
(F) The core column 4 reduces rainwater falling into the pit, and takes measures against rainfall from the viewpoint of protecting the related mechanism of the pulley 5 and the weight 6.
(G) The pit 4 is intended to match the floor level of the living space 2 and the level of the surrounding ground, but it is intended to have a bottom height that can maintain a dry state during normal times.
(H) If the depth of the pit 4 cannot be taken and the floor level of the living space 2 and the level of the surrounding ground do not match, attempt to escape on the slope pier with a target of 8% or less, which is the limit gradient of the wheelchair. .
(I) The upper edge of the pit 4 is provided with safety measures such as a chamfered shape that makes it easy to swallow water, an inclination of the wall surface, and a fall prevention grating.
(Nu) Returning to the original position after the tsunami predicts laying of foreign objects, and considers lift-up equipment from the viewpoint of maintenance and inspection.

Claims (1)

A living space 2 with a roof 3 is integrally constructed on a float 1 having a flat circular shape and a flat deck that seals the upper part of the bottom of the ship that is gradually reduced in diameter toward the bottom. A well-shaped hollow portion penetrating the living space 2 and the roof 3 is provided, and a core column 4 having a rectangular or spline mechanism, which is sufficiently higher than the assumed height of the tsunami, is passed through the hollow portion. Floating tsunami evacuation boat that is slidably fitted to pillar 4 only up and down.
