Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of constructing a concrete pavement,

TECHNICAL FIELD [0001] The present invention relates to a pavement body having improved water retentivity and water permeability by using a porous mixture, a method of constructing a pavement body, and a concrete pavement (formwork).

The one described in Patent Document 1 is known as a package having water retentivity and water absorbency. The package described in Patent Document 1 is composed of a surface layer, a roadbed, and a road floor at least in the order from the top, and the surface layer is made of a packing layer made of asphalt having a predetermined degree of opening degree Is filled with water-repellent cement milk to form a water-repellent surface layer.

Patent Document 1: JP-A-2008-156944 Patent Document 2: JP-A-2002-250001

However, in the configuration of the related patent document 1, there is a problem that water exceeding the water content overflows on the road surface. In addition, if the water in the maintenance water evaporates, the heat island heat or solar heat accumulated in the surface layer may be released, which may cause a heat island phenomenon which raises the outside temperature.

On the other hand, in the case of Patent Document 2, since a water permeable packing member is laid on a rolling bearing and then impregnated with a water retaining slurry material in a planar direction from the surface of the water permeable packing portion, the packaging operation is very troublesome.

In the case of the surface pavement package structure in which the inclination in the road width direction is applied at the same inclination at a certain distance in the direction from the center to both ends and the inclination of the remaining distance is steeper than the above inclination as in the conventional case, , It is possible that water with a water content exceeding the maintenance and permeability flows into the main sewer main body at one time and flows backward beyond the drainage ability of the main sewer main body And a problem that a traffic obstacle occurs when a bicycle or a motorcycle passes through a roadside zone.

An object of the present invention is to solve the above-mentioned problem by reviewing the structure of a material or a package used in a package.

In order to achieve the above object, the present invention provides the following means.

That is, the package according to the present invention is characterized in that it comprises at least two layers of a porous aggregate material mixture of a porous material and a cementitious fire (solidifying material), followed by a surface layer material having a water permeability function have.

With this configuration, the package has water retentivity and water permeability, so that water can be stored in the upper part of the hearth, and water can be appropriately impregnated in the hearth. Accordingly, when the rainfall is increased, the drainage is improved and the water is stored in the package, thereby reducing the excessive flow of water into the hearth. In addition, when the drought continues, the water stored in the package is sucked up, Since the water is sucked up through the package, the temperature rise of the surface layer can be effectively suppressed.

At this time, in order to adjust the amount of the permeate to the road bed to a sufficient amount, it is necessary to form a semi-permeable layer (semi-permeable layer) having a permeability function and a blocking function at the boundary between the porous aggregate mixture and the hearth below the porous aggregate mixture, Is preferably formed.

It is effective to make the semi-aeration layer be inclined in the direction of the drain pipe in order to appropriately guide the water of the river water to the drainage facilities and the like.

In order to eliminate the street ditch, the surface layer material from one end to the other end in the width direction is laid flat so as to form the packaging surface of the road without giving a transverse gradient from the center in the width direction to the both ends, .

As another structure for realizing the same purpose, a surface layer material having a water permeability function is formed so as to form a packing surface of the road by giving a constant transverse gradient between the center to the end and the center to the other end in the width direction ≪ / RTI >

Further, in order to allow water of a large amount of water to flow into a drainage facility or the like, it is preferable to tilt the semi-aeration layer in the direction of the drain pipe.

In order to alleviate the phenomenon of "re-kneading", which is caused by intrusion of rainwater or the like that has penetrated to the deepest portion into the hearth and sinking due to vibration from the surface layer surface, a cement- It is preferable that a crushing roadbed is laid under the above-mentioned porous aggregate mixture, and a porous material not containing a mixture such as a fire or the like is further disposed thereunder.

It is preferable to use a clinker ash as the porous material in order to carry out the present invention at low cost and to contribute to this ecology through reuse of industrial waste.

In order to lay the pavement without excavating the roadway of the present road, the pavement is removed to expose the hearth, and a surface layer portion composed of a middle layer portion composed of a porous aggregate mixture and a surface layer material having a water permeability function is sequentially It is preferable to construct the package and apply the package.

In order to construct an effective pavement by a new construction, it is necessary to use a base material composed of a porous material not containing a mixture such as a fire or fire, a second middle layer made of a crushed stone roadbed, an intermediate layer made of a porous aggregate mixture, It is preferable that the surface layer portion made of ashes is sequentially applied from the bottom to the top to construct the package.

In addition, the mold for concrete according to the present invention is formed by molding a porous aggregate mixture in which a porous material and cementitious firefly are mixed into a plate shape, and concrete is placed inside and is buried again as a part of the concrete structure .

When such a mold frame is used, the mold frame has excellent water permeability and water absorbency, and discharges the excess water (extra water, extra water) generated during the pouring of the fresh concrete to the outside, Is gradually caught in the inside of the mold and supplied to the inside in response to the heat of reaction at the time of curing of the concrete, thereby making it possible to secure the hardness of the concrete structure. In addition, the number of bleeding which is a strong alkaline water is inevitable due to treatment such as neutralization with sulfuric acid at the time of pouring fresh concrete, but most of the bleeding water is caught in the inside of a mold.

Further, in the package of the present invention, a porous mixture of a porous material and a cement-based fireproofing material is laid on a concrete over-hanging base to a base portion to form an intermediate layer portion, , And a surface layer material is laid to form a surface layer portion, thereby forming a roadbed having water absorbency and water permeability in the grooves of the train.

When the above-mentioned package having the watertightness and the water retention property is attached to the groove top of the train, the temperature rises regardless of the place where the direct heat is blocked in the summer due to the influence of the outside temperature and the heat storage of the train body. Temperature rise can be suppressed.

As described above, in the present invention, since the package is formed of a material having water-retaining property and water permeability, water can be appropriately permeated into the hearth as well as the repair, so that the water is sucked up at the time of drying, Even if there is no supply of moisture to the roadbed for a long period of time, the temperature rise of the surface layer can be suppressed by sucking moisture from the hearth. In addition, since water can be absorbed from any place of the asphalt of the surface layer and can be repaired at any place, it is possible to make the structure that drainage is good and does not generate a puddle, etc. In addition, A large amount of water does not flow at one time, and a large amount of water can be prevented from flowing into the drain pipe.

(First Embodiment)

1 is applicable to roads of the so-called L traffic {less than 100 (large) / day (day) direction), and furthermore, B traffic {250 to less than 1000 (large / Layered portion 12 made of a porous aggregate material mixture (a) obtained by mixing a cement-based fireproofing material with a clinker ash (CA), which is a porous material, is laid on the packaging section 1 of the package 1 according to the present embodiment. A surface layer portion 11 made of a material (b) having a water permeability function is laid, and these two layers constitute a roadbed 1a.

Clinker ash contains about 15% of coal ash generated after high-temperature combustion (1300 ℃) of finely pulverized coal in a thermal power plant or steel mill, and the burnt particles cohere with each other in the boiler, It falls into a water tank, and the rest is called a fly ash. In the past, all of these had been disposed of as industrial waste. Since there are many fine holes in the clinker ash, the surface area is large. Therefore, it is very light and not only excellent in water permeability, but also has a sufficient water retention capacity to store about 40% of the volume of water. Thus, in the present embodiment, the clinker ash is employed as the package body 1, in addition to the reuse of resources, in order to give the road a function of drainage and a function of sucking water. Since most of the composition of the clinker ash is composed of silica or alumina, the aggregate strength is strong and there is no fear of strength after use (after the addition). In this embodiment, the porous aggregate mixture (a) obtained by cementing at least cement mortar to a certain amount of coal ash having a specific particle diameter is solidified and used. The mixing ratio is, for example, 1: 0.14 to 0.15. In the mixing, since the clinker ash is burned at a high temperature, there is no organic matter (roots or germs in the plant) in the material, and there is an advantage of facilitating the reaction such as solidification in mixing at the time of use (processing).

Although fly ash contains silica or alumina, it is in the form of a powder that is likely to adhere to the wall surface of the boiler, and since the snow is too small, when the cement based fire is kneaded, the snow is clogged in a clogged state and desired water permeability and water retention can not be expected Therefore, it adopts a clinker ash having a larger particle diameter than that.

Since the cleaner ash has excellent water retention and water absorbing properties, it contains moisture even if left untreated. However, if water is contained, it hardens and becomes clogged when kneaded with a cement based fire, and if the water content is low, the solidification becomes insufficient and the strength becomes insufficient. Therefore, it is necessary to solidify the porous aggregate mixture (a) by advancing the reaction of cementitious fire so as not to block the snow while injecting necessary moisture (clean water) and admixture.

As a preferred embodiment of this case, the particle size of the main aggregate asinker is 20 mm or less (provided that 0.074 mm or less is within 5% of the total), the blending ratio of the porous aggregate mixture (a) (Dry soil) weight ratio) was set to be 0.11 to 0.25 of fresh water and an admixture (150 to 200/1 dilution) to the porous aggregate mixture (a) with the main raw material Clinker Ash: In addition, it was confirmed by the test that it was very effective to use.

Thus, it is possible to obtain a solidified product of the porous aggregate mixture (a) having the required strength while maintaining water retentivity and water permeability.

However, it is difficult to say that the above-mentioned porous aggregate mixture (a) is sufficient to be applied directly as a surface layer material on a pavement through which trucks having a large weight are loaded, such as traffic, Namely, there is a problem in the strength such as abrasion resistance, and in order to overcome this problem, it is necessary to mix a large quantity of fire and kneading with an expensive admixture because of the particle shape of the material. Because. Thus, in the present embodiment, the asphalt mixture (b) is laid as the surface layer material in the surface layer portion 11 and the middle layer portion 12 made of the porous aggregate mixture (a) using the clinker ash just below the surface layer is employed (1a) based on an entirely new concept of

The asphalt mixture (b) employs a water-permeable asphalt mixture which improves the strength by mixing aggregate with a part of so-called water-permeable asphalt having high permeability to water.

Regarding the pavement thickness, in the case of this embodiment, the thickness of the middle layer portion 12 by the cleaner ash mixture is 100 to 300 mm, and the surface layer portion 11 by the asphalt mixture is 40 to 50 mm. The pavement thickness of the entire layer is set to be substantially equal to the construction thickness of the usual asphalt mixture. Therefore, the construction is completed by removing the development package (asphalt) to expose the hearth A, and sequentially constructing the middle layer portion 12 and the surface layer portion 11 thereon. And it is also possible to avoid the disturbance of the hearth surface at the time of excavation and to carry out the construction. Of course, when constructing a new road, the thickness can be set to an optimum value in consideration of water permeability and the like, and it is not always necessary that the road is laid without excavating the road on the development road. When a new construction is carried out, the structure of Fig.

In this embodiment, the semi-order layer 13 is disposed at the boundary between the middle layer portion 12 composed of the porous aggregate mixture (a) and the hearth A below the middle layer portion 12. This semi-aeration layer 13 is made of an asphalt emulsion which can be sprayed or mixed at room temperature on the hearth A and is formed at the previous step of applying the intermediate layer 12 on the hearth A And it is designed not to completely acquire the water directed to the hearth (A) but to transmit a certain amount of water. Since the asphalt emulsion can be sprayed or mixed at room temperature, safety is very high because it considers the environment such as energy saving and CO2 suppression compared with the conventional method, and it is hard to cause fire or the like. In addition, at the time of laying, the relevant semi-aeration layer 13 is slanted by about 2 to 3 degrees in the direction of the drain pipe B buried in the road side, and the excess water not to be watered is supplied to the drain pipe B) to the drainage facility (C).

The package 1 according to the present embodiment having the above-described structure is obtained by providing the porous aggregate mixture (a) in which the porous material and the cementitious fire or the like are mixed to form the middle layer portion 12, and then the asphalt mixture b to form a surface layer 11 to form a roadbed 1a. Since the concrete mixture b having the water permeability function is used in the surface layer portion 11 and the porous aggregate mixture a is used in the middle layer portion 12 just under the surface layer portion 11, And water permeability can be appropriately applied to the hearth (A) below the two layers (11, 12). Therefore, at the time of drying, the water repaired in the middle layer portion 12 is sucked up through the surface layer portion 11, and the drought is continued, so that the roadbed layer 1a composed of the two layered portions 11, Even when there is no supply, the temperature rise of the surface layer portion 11 can be suppressed by sucking moisture from the hearth (A). Therefore, compared with the conventional package structure in which water is completely prevented from flowing into the hearth (A), the heat island phenomenon can be effectively prevented, which contributes greatly to the reduction of CO2.

In addition, even when the amount of rain is increased, the water absorbing property and the water permeability are excellent, so that water can be absorbed from any place in the surface layer portion 11 and the water can be repaired at any place, It prevents water from flowing into the drainage facility (C) in a large amount, and becomes very effective as a countermeasure against disasters such as landslide disintegration due to urban decay and disintegration of the embankment. In the present package 1, if the amount of precipitation per hour is about 70 mm, the surface drainage is unnecessary, and the inside of the package 1 and the outflow of water are supplied to the hearth A, and the clinker ash has a volume of 40 (B) of Yeosu soils can be drained by setting them at regular intervals. Therefore, when the water content exceeds the upper limit of the surface layer portion (such as a puddle) 11) can be effectively reduced.

In addition, the package 1 of the present embodiment is characterized in that, at the boundary between the middle layer portion 12 of the porous aggregate mixture (a) and the hearth (A) below the middle layer portion 12, It is possible to appropriately adjust a plurality of excessively large amounts of water (covering water and flowing water) to the hearth (A) and, conversely, difficulty of draining the bedding (1a).

Particularly, since the semi-aeration basin 13 is inclined toward the drain pipe B, if water of a large amount of water is made to flow to the drainage facility C or the like, the excess water after permeating water into the hearth A by an appropriate amount, The water flows smoothly in the direction of the drain pipe B along the inclination so that the water does not remain in the surface layer portion 11 and part of the water impregnates into the hearth A and further the water of the peripherals is appropriately drained.

2, the surface layer 11 is provided with the asphalt mixture which is the surface layer material without giving a transverse gradient from the center 11a in the width direction of the road to the both ends 11b thereof, (b) can be laid flat so as to form the packaging surface of the road. That is, in the conventional road pavement 31 shown in Fig. 7, since it is thought that water can not be allowed to flow into the roadway A, A transverse gradient of about 2% toward the lower right is provided in the region m near the end portion 31b from the center 31a in the widthwise direction of the road in addition to the constitution of forming an oily film to block the water permeation, (D) made of concrete having side grooves or the like so that the lateral side portion n of the side portion n is provided with a crossing gradient from the drainage facility (E) to the drainage pipe F). And a reverse gradient from the center 31a to the opposite side. Therefore, in addition to the concentration of rainwater near the road side n, there is a problem that the drainage ability is overcome, and a dangerous condition can not be avoided in the bicycle or the motorcycle passing through the roadside zone n. On the other hand, in the structure of Fig. 2, the roadbed 1a is excellent in water permeability, and absorbs water from any place in the surface layer portion 11, It is possible to drain to the porous tube 14 or the drain without overtaking the drainage capability without providing the gauges D having the gradient shown in FIG. Therefore, the rainwater does not concentrate near the road side n, and the risk of the bicycle, the motorcycle or the like passing through the road side n can be effectively avoided. In these figures, reference numeral 101 denotes a sidewalk packed with an asphalt mixture, and reference numeral 102 denotes a concrete partition which defines the edge portion of the sidewalk 101.

Since the package 1 uses the cleaner ash as the porous material, it can be constructed by obtaining the material free of charge or inexpensively, and contributes greatly to this collage through reuse of industrial waste .

2, the surface layer portion 11 having a water permeability function is disposed between the center 11a and the one end 11b in the width direction and between the center 11a and the other end 11b (For example, about 2%) may be given between the two sides of the road surface. As described above, if the inclination is constant and the inclination is gentle, the concentration of the rainwater on the side portion n of the road side is alleviated, and the passage obstruction of the bicycle or the motorcycle passing through the road side portion n can be effectively solved, It is possible to more effectively perform drainage on the surface of the surface layer portion 11 in a range without difficulty.

Roads to which such a structure is applied can be applied to sidewalks as well as cars driven by cars.

(Second Embodiment)

3, after the porous aggregate mixture (a) is laid to form the middle layer portion 22, the permeable asphalt mixture (b), which is a surface layer material having a water permeability function, is laid on the surface layer portion 21, It has basically the same absorption function and permeability function as that of the roadbed 1a of the above embodiment. In this embodiment, furthermore, the crushed stone roadbed (c) is disposed at the lower part of the middle layer portion 22 made of the porous aggregate mixture (a) to form the second middle layer portion 23, And the base material 24 is formed by disposing the porous material d which does not contain the porous material d. The porous aggregate mixture (a) is a mixture of at least a cement fireproofing material and a cementitious fireproofing material, which is solidified in a clinker ash, and the marking material (b) is a water permeable asphalt mixture. In the crushing roadbed (c), 1: 1 mixture of cement concrete and crushed stone is used. The porous material (d) not containing the mixture is the granular material of the clinker ash itself.

3, the thickness of the middle layer portion 22 made of the porous aggregate mixture is designed to be thinner than the middle layer portion 12 shown in Fig. 1 in the range of 100 mm to 300 mm, 21 are designed so as to have a thickness in the range of about 40 mm to 50 mm, so that the design according to the circumstances is made to be substantially equal to the roadbed 1a shown in FIG. 1 as a whole. The base portion 24 made of the porous material (d) containing no mixture is thicker than any of the above layers, and is set to, for example, about 300 mm. The base portion 24 is preliminarily installed by drilling the hearth A in a depth of about 300 mm to a degree suitable for the hearth. Therefore, it is effective when constructing a new road.

Also in this case, as a preferred embodiment, the mixing ratio (dry soil weight ratio) of the porous aggregate mixture (a) is not more than 20 mm (note that 0.074 mm or less is within 5% , It is very effective to add fresh water of 0.18 to 0.25 and an admixture (diluted to 150 to 200/1) to the porous aggregate mixture (a) with the cement kiln ash as the main material: cement fireproofing = 1: 0.07 to 0.2 It was confirmed by the test.

With this configuration, since the base portion 24 adjusts the water content of the road bed soil, the road surface A prevents sudden absorption of a large amount of water, and rainwater, etc., Quot; re-kneading " phenomenon, which is caused by vibrations caused by vibration from the surface layer portion 21 in the state of entering into the container portion A, can be effectively alleviated. Since the roadbed 2a is supported on the crushed stone roadbed c, it is possible to effectively form the base portion 24 made of the porous material d of the deepest portion after the water permeability and the strength are maintained.

(Another application example 1 of the package of the present invention)

The package body 4 shown in Fig. 4 is an example in which the present invention is applied to constitute a roadbed of a parking lot, and a porous aggregate mixture (a) containing at least a mixture of a clinker ash as a porous material and a cement- (C) is formed on the lower part of the middle layer portion (42) made of the porous aggregate mixture (a). The surface layer portion (41) And a base portion 43 made of a base material 43 made of a steel material and constituting a roadbed 4a having water permeability and water permeability, 44 so that the water is guided to the water storage tank G. As shown in Fig.

In a typical parking lot, rainfall is treated as external (public sewerage) via drainage in the ground by surface drainage. When the package body 4 is used in such a parking lot, it is excellent in water permeability and water retention, so that a water tank G as described above is provided under the parking lot without flowing the water into the sewer, and the water tank G is stored in the water tank G , And the water in the water tank (G) can be reused as a toilet in a shop or a garden. The capacity of the installed reservoir (G) needs to be capable of storing at least 80% of the amount directly treated with the current sewerage. As a facility, it is preferable to provide a pre-watering facility in a suitable place in the parking lot, and to allow the water in the upper water tank (G) to sprinkle on the package body (4) when the temperature in the summer is high and water evaporation is intense . By reducing the surface temperature of the surface layer 41 having a large area in a large-sized leisure facility or a shopping mall or the like, the heat island phenomenon can be alleviated and resource savings can be achieved by reusing rainwater through the water tank G , It is possible to prevent a disaster when a lot of rain comes.

(Another application example 2 of the package of the present invention)

The package 5 shown in Fig. 5 shows an example in which the present invention is applied to a platform of a train, in which a porous mixture (a) using a cleaner ash is laid on an existing concrete top plate (A ') And the surface layer portion 51 is formed by laying a water-permeable flat plate block b 'as a surface layer material on the middle layer portion 52 and forming a roadbed 5a having absorbency and water permeability . Since the existing concrete upper plate A 'overhangs the base portion Z under the existing concrete upper plate A', the excess water permeating the roadbed 5a is discharged downward from the overhang portion.

The grooved image of the train increases the temperature regardless of the place where the direct heat is cut off in the summer due to the influence of the outside temperature and the heat storage of the main body of the train. However, with this package 5 having the water- Can be suppressed.

In the case of the railway grooves, the roof is installed outside and the sunlight is directly received or directly exposed to rainfall. However, since the roof receiving the sunlight is stored in summer and the train body is heated, Is difficult to suppress. Therefore, by constructing the package 5 having excellent water retentivity and water permeability as shown in the figure in the groove of the foot, the heat of the surface layer portion 51 can prevent the heat of evaporation It is possible to suppress an increase in the temperature of the entire groove by using the characteristic of depriving the ambient temperature.

In this case, as a preferred embodiment, the blending ratio of the porous aggregate mixture (a) (dry soil weight ratio) of the main aggregate cleaner ash is 20 mm or less (provided that 0.074 mm or less is within 5% It is very effective to add the fresh aggregate mixture (a) with fresh water of 0.18 to 0.25 and an admixture (150 to 200/1 dilution) to the main aggregate as a main material, Clinker ash: cement fireproofing = 1: 0.10 to 0.20.

(Another application example of the porous aggregate mixture used in the present invention)

6, when the large-sized concrete structure X such as the drainage facilities C and E or the water storage tank G is constructed, the mold frame 200 is formed by using the porous aggregate mixture (a) Is effective.

That is, at the time of making the body of the concrete structure (X) or the like, it usually takes time to measure the slump value of the live concrete when constructing the concrete structure. Further, if the slump value is large, sufficient strength of the concrete structure X is not maintained. In addition, since the mold is usually a tree, the wood debris is mixed into the concrete structure (X) to affect the strength. Thus, similarly to the above, the cement-based fireproofing agent is kneaded into a cleaner ash, which is a porous material, to produce a porous aggregate mixture (a), and an admixture, fresh water and the like are kneaded and molded into a plate having a thickness of 30 to 50 mm. The concrete structure X is used as the mold 200 of the concrete structure X. After the concrete is poured into the inside of the concrete structure X, only the support work 300 is removed,

In this case, as a preferred embodiment, the particle size of the clinker ash is 0.074 mm to 25 mm and the mixing ratio (dry soil weight ratio) of the porous aggregate mixture (a) is from 1: 0.15 to 0.25 as the main material of clinker ash: , And it was confirmed by the test that it is very effective to form the porous aggregate mixture (a) by adding a fresh water of 0.18 to 0.25 and an admixture (150 to 200/1 dilution) and applying a load (1000 kg or more).

The mold 200 has excellent water permeability and water absorbency and discharges the water generated during the pouring of the fresh concrete to the outside and keeps moisture required for curing in the inside of the mold 200 by the maintenance function So that the hardness of the concrete structure X can be ensured by gradually supplying it to the inside in accordance with the heat of reaction at the time of curing of the concrete. Further, when the fresh concrete is poured, the bleeding water, which is a strong alkaline water, is pinched by treatment such as neutralization with sulfuric acid, but most of the bleeding water is caught in the inside of the mold 200.

When a wooden panel is used for a mold frame, there is a possibility that garbage is generated and garbage generated inside the structure is mixed at the time of concrete pouring, which may affect the strength of the structure. However, have.

In addition, since the processing is easy while having the strength, the working efficiency is also improved.

The slump of the raw concrete can also be set to a viscosity of usually about 8 to a viscosity of 12 or more and the fluidity is improved so that the working efficiency of the pouring is greatly improved and the panel is filled with the bleeding water, (Defect part where only aggregate aggregated when concrete is poured, that is, a defect part having only gravel and few sand and cement) is also eliminated.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. For example, if the porous material has permeability, water retention, and strength other than the cleanser ash, And various modifications may be made without departing from the spirit of the present invention.

≪ Industrial applicability >
