Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water area structure comprising two rows of walls provided in a water area such as a harbor, a fishing port, and a coast.

[0002]

2. Description of the Related Art Conventionally, a double-walled structure provided in a water area such as a harbor or a fishing port is constructed by placing a wall component such as a steel sheet pile or a steel pipe sheet pile on a bottom of the water while fitting the joint thereof. Two rows of continuous walls are constructed at a predetermined interval, and the heads of the two rows of continuous walls are connected with tie material. It was built by construction. There are two methods of connecting the heads of the continuous walls: a tie material bonding method and a top plate bonding method.

[0003]

As described above, in a conventional double wall structure provided in a water area such as a harbor or a fishing port,
It is common sense that the filling material is filled to the vicinity of the top end of the double wall, and no hollow chamber is provided at the top. This is considered to be due to the fact that there is no design method when a hollow chamber is provided in the upper part.

[0004] On the other hand, the inertial force acting on the filling material during an earthquake is proportional to the total mass of the filling material. Therefore, in the conventional double-walled structure, (a) during an earthquake, a large earth pressure (inertial force) acts on the wall from the horizontal direction, and accordingly, a large rotation occurs on the entire structure. The force acts and gives a large load to the foundation ground. In addition, (b) due to the structural property of resisting the horizontal external force by the shear resistance of the filling soil, the horizontal deformation such as the horizontal displacement at the top end is large until the shear resistance of the filling sand is developed. There was a problem of becoming.

The following measures have been taken to solve the problem (a). A member having great rigidity is used for the wall. Gravel material with a large internal friction angle is used as fill sand to increase the shear resistance due to fill sand. In the case of the top plate connection type, the width of the wall (the width of the filling soil) is increased in order to reduce the axial force generated on the wall.

[0006] In the case of the above measures, there is a problem that a wall constituting member having a large cross-section is required, which hinders production, transportation, construction and the like of the member. In the case of the above-mentioned countermeasures, there is a problem that economical efficiency is hindered because the gravel material is expensive. In the case of the above-mentioned countermeasures, if the distance between the walls is increased, the width of the filling soil is also increased, so that the seismic inertial force acting on the filling is also increased, and the wall width is not determined depending on the design seismic intensity. There was a design problem.

There is no concrete countermeasure for the problem (b). For this reason, it is desired to develop a double-walled structure having a high degree of freedom in design that does not require a large space between the walls (width of the filling soil) and the cross-section of the wall-constituting members and can control the deformation. I was

Further, the conventional double-walled structure has a wave-dissipating effect when the joint of steel sheet pile or steel pipe sheet pile extends to the inside of the superstructure, and seawater permeates the front and rear continuous walls. It was an impermeable structure in which there was no slit for water flow to be exhibited. Furthermore, since there is no hollow chamber that plays the role of a water-reducing chamber necessary for exhibiting the wave-eliminating effect, there is a problem that the wave-eliminating effect cannot be exhibited and the reflected wave height cannot be reduced. In addition, since the structure is impermeable, there is a problem that seawater does not permeate from the structure body, resulting in deterioration of water quality in the embankment. For this reason, development of a double-walled structure having a wave-dissipating function and a seawater transmission function has been desired.

The present invention solves the above-mentioned problems by combining the invention of the fitting range of the wall component, the design of the height of the top of the filling material, the arrangement of additional members, and the like. .

According to the present invention, in a double-walled structure, an inertial force during an earthquake can be reduced by providing a hollow chamber between two rows of walls. For this reason, unlike the conventional double-walled structure, a large earth pressure does not act on the wall due to the inertial force acting on the filling soil during an earthquake, and a large rotational force does not act on the entire structure. Therefore, there is no need to use a member having high rigidity for the wall or to increase the space between the walls to increase the shearing resistance due to the filling soil, thereby reducing the construction cost.

Further, in the present invention, by providing a slit for water passage at a predetermined position on one or both continuous walls,
A reflected wave countermeasure function and a seawater circulation function can be provided.

Further, according to the present invention, when the continuous wall of the double-walled structure is formed to have a water-permeable slit or the like through which seawater can permeate, the water-reducing chamber of the water-reducing chamber required to exhibit the wave-damping effect is provided. Since the hollow chamber plays a role, the wave-breaking effect can be exhibited, the reflected wave height can be reduced, and the seawater can be transmitted, so that the deterioration of the water quality in the embankment can be prevented.

In particular, in the present invention, by arranging the columnar members and the diagonal members, it is required in places where severe wave conditions such as large depths and high wave areas, and load conditions during earthquakes such as inertial force and dynamic water pressure accompanying earthquakes are severe. A horizontal load carrying function (load carrying capacity, deformation performance) can be ensured.

Further, by increasing or decreasing the number of columnar members and diagonal members and the rigidity of the members, the horizontal load-bearing function (load-bearing force, deformation performance) as a structure can be adjusted and secured.

Further, by changing the interval between the two rows of walls and the height and shape of the lower layer of the hollow chamber, it is possible to adjust the inertial force and the wave-dissipating function acting on the filling material.

[0081]

According to the present invention, the inertial force during an earthquake can be reduced by providing hollow chambers between two rows of walls in a double-walled structure. For this reason, unlike the conventional double-walled structure, a large earth pressure does not act on the wall due to the inertial force acting on the filling soil during an earthquake, and a large rotational force does not act on the entire structure. Therefore, there is no need to use a member having high rigidity for the wall or to increase the space between the walls to increase the shearing resistance due to the filling soil, thereby reducing the construction cost.

Further, in the present invention, by providing slits for water passage at predetermined positions of one or both continuous walls,
A reflected wave countermeasure function and a seawater circulation function can be provided.

Further, according to the present invention, when the continuous wall of the double-walled structure has a permeation structure having a water passage slit or the like through which seawater can permeate, the water retarding chamber necessary for exhibiting the wave-damping effect is provided. Since the hollow chamber plays a role, the wave-breaking effect can be exhibited, the reflected wave height can be reduced, and the seawater can be transmitted, so that the deterioration of the water quality in the embankment can be prevented.

In particular, in the present invention, by arranging the columnar members and the diagonal members, it is required in places where severe wave conditions such as large depths and high wave areas, and load conditions during earthquakes such as inertial force and dynamic water pressure accompanying earthquakes are severe. A horizontal load carrying function (load carrying capacity, deformation performance) can be ensured.

Further, by increasing or decreasing the number of columnar members and diagonal members and the rigidity of the members, the horizontal load-bearing function (load-bearing force, deformability) as a structure can be adjusted and secured.

Further, by changing the interval between the two rows of walls and the height and shape of the lower layer of the hollow chamber, the inertial force and the wave-dissipating function acting on the filling material can be adjusted.
