Description

[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a roof erection structure corresponding to a deformed flat surface of a new or existing waste disposal site.
[0002]
[Prior art]
The conventional waste disposal site is constructed using the natural topography of the valley to minimize the amount of cut-off work and to match the terrain to secure the capacity. It was an open shape without applying a complicated covering structure directly on top. Also, there was no idea to cover the existing open disposal site later.
However, in recent years, the safety issues of leachate at final disposal sites have been highlighted, and so-called covered disposal sites that control the supply of rainwater, which is the source of leachate, have been planned and constructed nationwide. . However, the roof structure was limited to a square structure.
The roof structure of such a conventional waste disposal site with a roof is an application of a general roof structure, and requires multiple supports to support the roof load. This has become a major constraint when applied to large-scale disposal sites that require intermediate struts that may cause damage.
In addition, it is basically based on the premise that it is rectangular in a plane, and is not suitable for application to the covering structure of a disposal site with an irregular shape or a curved surface with an irregular shape such as the existing disposal site. Met.
[0003]
Thus, the need for roof erection at existing large-scale industrial waste disposal sites has been increasing due to heightened environmental awareness, and this tendency is particularly noticeable in landfills that are being reclaimed.
However, conventional roof erection at a large-scale industrial waste disposal site assumes that it is a so-called "dome-shaped" shape that is convex toward the upper side, and the roof and columns are entirely compressed structures. The distance between the spans cannot be so large. On the other hand, in the conventional roof erection on a large-scale industrial waste disposal site, the length between the columns required as the center span is a very large value of 100 m to 200 m. For this reason, there is no realistic proposal for roof construction at such a large-scale industrial waste disposal site.
[0004]
[Problems to be solved by the invention]
As described above, the construction of a final disposal site for industrial waste, whether it is a new one or an existing one, has a structure that can cover the disposal area even if the planar shape is irregular, solving the problem of leachate and reduction of management costs In addition, it is an issue for the roof erection structure of the waste disposal site to be able to cope under negative pressure conditions in order to prevent odor, harmful gaseous substances, and dust from being scattered and diffused outside the area.
The present invention has been proposed in view of such a problem, and can be applied to a disposal site having a deformed shape in a plane regardless of whether it is new or existing. A roof covering structure of a waste disposal site that realizes a long span coating structure of 100 m to 200 m based on a membrane or the like and has a low construction cost and can prevent inflow of rainwater and emission of harmful substances to the atmosphere. The purpose is to provide.
[0005]
[Means for Solving the Problems]
In the roof erection structure corresponding to the deformed flat surface of the waste disposal site according to the present invention, a plurality of pillars (2a, 2b) are erected around the waste disposal area, and the pillars (2a) at an opposing position from the pillars (2a). ), Horizontal and vertical main cables (3, 4) supporting only the pulling force above the waste disposal area (1) are stretched, and these horizontal and vertical main cables (3, 4) are extended. ) Are connected to each other at the intersections and support a roofing material (5) made of a membrane, and the roofing material (5) has gravity at least in parts other than the support part by the main cables (3, 4). It is stretched so as to be convex in the direction (claim 1).
[0006]
The roof erection structure corresponding to the deformed flat surface of the waste disposal site of the present invention having the above-described configuration is, for example, a waste disposal site constructed in an area depressed from the surroundings (for example, a mountain valley or the like). It is intended for roof erection in the waste disposal area (1), and since the roofing materials (5, 50) stretched as roofing materials are stretched so as to be convex in the direction of gravity, the columns (2a, 2b) and The horizontal and vertical main cables (3, 4) and the roofing material (5, 50) constitute a tensile structure.
As is well known, in the case of a tensile structure, the span between the columns (2a, 2b) can be much longer than that of the compression structure. Therefore, even in the case of a long span (100 m to 200 m) in which the roof material cannot be stretched by the conventional dome-shaped roof erection structure which is convex upward, the roof material (5, 50 ) Is stretched so as to be convex in the direction of gravity, whereby the roof material can be stretched between the pillars (2a, 2b) without further erection of the pillar in the intermediate region.
Furthermore, according to the present invention, a high-flexibility horizontal main cable for suspension suspended between columns (2a, 2a / 2b, 2b) opposed to each other above the waste disposal area (1). (3) and the longitudinal main cable (4) are connected to each other, and the entire waste disposal area (1) is covered with a roofing material (5 or 50) using the main cables (3, 4) as support members. Because it is covered, it can be adapted to a disposal site with a long span of 100 m to 200 m, and the construction cost can be reduced.
[0007]
The roofing material (5, 50) has a mechanism (B, 6, 7) for collecting rainwater collected on the roofing material and discharging the collected rainwater out of the waste disposal area. Item 2).
[0008]
As described above, since the water collecting and draining mechanism (B, 6, 7) is provided, the rainwater flows into the waste disposal area (1), and the harmful substances contained in the waste are dissolved in the flowing rainwater. Can be prevented.
In addition, the weight of the water collecting and draining mechanism (B, 6, 7) acts on the roof material (5, 50) so that the roof material (5, 50) becomes convex in the direction of gravity. Compensation for being stretched. As a result of the roof material (5, 50) being stretched so as to be convex in the direction of gravity, the length (span) between the columns (2A, 2b) is made extremely long by using the entire roof erection structure as a tensile structure as described above. And the location where the water collecting and draining mechanism (B, 6, 7) of the roofing material (roofing material: 5, 50) is attached is particularly depressed downward, so that rainwater and the like are collected and drained. The drainage can be efficiently performed by the mechanism (B, 6, 7).
[0009]
Further, the interior of the waste disposal area (1) entirely covered with the roofing material (5 or 50) is maintained at a negative pressure by negative pressure generating means (claim 3).
In this way, since the interior of the waste disposal area (1) is maintained at a negative pressure by the negative pressure generating means, harmful gases and odors are prevented from being emitted to the atmosphere.
[0010]
Further, a photovoltaic power generation means (8) is attached to the upper surface of the roofing material (50) (claim 4).
And / or a wind power generation means (80) is attached to the top (2d) of the column (2a, 2b) (claim 5).
[0011]
Power generation means (photovoltaic power generation means 8 and wind power generation means 80) are provided on the top surface of the roofing material (50) and / or on the top (2d) of the columns (2a, 2b). The driving energy of the negative pressure generating means (60) for maintaining the electric power, the electric power for indoor and outdoor lighting, and the like can be supplied by itself.
[0012]
Here, with respect to snowfall or snowfall, a means for generating heat (for example, a nichrome wire or another heating wire) is embedded in the roofing material (50), and the heat is generated by the power generating means (photovoltaic power generating means 8, wind power generating means 80). It can be configured to activate the application means to melt the snow layered on the roofing material.
[0013]
In addition, when dust, dust, pebbles, and other powders such as yellow sand are stacked on the roofing material, unlike the case of rainwater or molten snow, the water collecting and draining mechanism (B, 6) is used as it is. , 7) and may stay on the way.
In order to cope with such a case, a vibrating means (a vibrator or the like) is provided on the column (2a, 2b), and the vibrating means is operated by the power generating means (the solar power generating means 8, the wind power generating means 80). The struts (2a, 2b), the roofing material (5, 50), and the water collecting and draining mechanisms (B, 6, 7) can also be configured to vibrate.
[0014]
With this configuration, even if dust such as yellow sand, dust, pebbles, and other powders accumulate on the roofing material or stay in the water collecting and draining mechanism (B, 6, 7). By vibrating the column (2a, 2b), the roofing material (5, 50), and the water collecting and draining mechanism (B, 6, 7) by vibrating means, sand or dust such as yellow sand accumulated or accumulated, Pebbles and other particulate matter flow and are removed via the water collection and drainage mechanisms (B, 6, 7).
