Description

[0001]
BACKGROUND OF THE INVENTION
This invention relates around the square at the installation was ground surface drainage squares or the like compaction Way Method compacting by compaction device.
[0002]
[Prior art]
Conventionally, in ground leveling work on roads etc., when compacting the ground surface with drainage dredges etc., apply the compaction device plate directly to the ground surface for compaction in the same way around the dredge Is going.
[0003]
[Problems to be solved by the invention]
However, according to the above conventional compaction method, when two or more scissors are installed at an interval narrower than the plate width dimension of the compaction device, the compaction device cannot be brought close to the periphery of the scissors, You may not be able to fully compact the ground surface around the fence. If the compaction is insufficient, the pavement will sink around the fence, causing a problem that the fence protrudes. In particular, in the case of a small-diameter ridge, the interval between adjacent ridges is narrow as described above, and it is often impossible to perform compaction, resulting in the settlement of the pavement around the ridge.
In addition, drainage slag etc. is often made of vinyl chloride resin, etc. When the compaction device is brought close to the heel to compact the ground surface around the heel, the compaction device collides with the heel and breaks the heel. There is also a risk of letting you. For this reason as well, it is difficult to perform sufficient compaction around the heel.
[0004]
The object of the present invention is to compact the ground surface around the heel without damaging the heel, and even if the distance between adjacent ridges is narrow to some extent, it is possible to compact the heel due to insufficient compaction. it is to provide a compacted way method of squares around the subsidence around the pavement can be prevented.
[0005]
[Means for Solving the Problems]
According to the present invention, there is provided a method for compacting the periphery of the heel by disposing an annular compaction jig surrounding the periphery of the heel with a gap on the outer peripheral surface of the heel on the ground surface where the heel is installed. This is a method of compacting the ground surface from above with a compaction device. The compacting device may be one that performs compaction by applying vibration or the like, that is, one that performs rolling, that is, one that is mechanically compacted by static pressure.
According to this method, an annular compacting jig is arranged around the cage, and pressure and vibration are applied by the compacting device from above, so the compacting device interferes with the ground surface protrusions around the cage. Is avoided. Therefore, even if two or more ridges are installed close to each other and the distance between the ridges is narrower than the plate width dimension of the compaction device, the compaction device can be used to compact the ground surface around the collar with the compaction jig. It can be securely compacted. In addition, there is no possibility that the compaction device collides with the scissors and damages the scissors, and the periphery of the scissors can be securely compacted to the vicinity of the scissors. For this reason, the pavement around the fence due to insufficient compaction is prevented.
[0006]
In the compaction method of the present invention, the jig may be used at the time of re-consolidation. That is, the ground surface on which the fence is installed is compacted by a compaction device including the periphery of the fence, and the ground surface is surrounded by a ring around the periphery of the fence with a gap between the outer peripheral surface of the fence. Alternatively, a compaction jig may be arranged, and the ground surface may be compacted again from the upper surface of the compaction jig by a compaction device.
In the case of this method, as a first step, the ground surface including the periphery of the ridge is compacted, and only the periphery of the ridge that is difficult to compact is re-consolidated with an annular jig interposed, thereby Secure compaction is possible. Also, compaction work efficiency is good.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to FIGS. The seam compaction method according to this embodiment is applied to leveling work before paving on a road or a paved surface in a site. This compaction method is used in the above-mentioned leveling work, when the pit 1 such as the drainage basin as shown in FIG. 2 (A) is installed, and when backfilling is performed, and when the crushed stone roadbed is corrected thereafter. This is a method of compacting the periphery of the ridge 1 on the ground surface G. The gutter 1 is cylindrical and is connected to the embedded pipe 11.
This compaction method uses a compaction jig 2 shown in FIG. The compaction jig 2 is formed in an annular shape that can surround the flange 1 (FIG. 2), as shown in the upper perspective view, the sectional view, and the lower perspective view in FIGS. . The upper surface 2a of the compacting jig 2 is a flat surface so that the plate 4 (FIG. 2B) of the compacting device 3 can be placed stably. The cross-sectional shape of the compacting jig 2 is generally an inverted trapezoidal shape, and a portion 2bb extending from the outer peripheral surface to the lower surface 2b, that is, the outer peripheral portion of the lower surface 2b is a convex curved surface having an arc-shaped cross section. The inner peripheral portion 2ba on the lower surface 2b of the compacting jig 2, that is, the peripheral portion of the central hole 2c is a flat surface. The material of the compacting jig 2 is, for example, a resin molded product made of polypropylene-based synthetic resin.
[0011]
In this first method, the ground surface G including the periphery of the kite 1 is directly compacted by the compacting device 3. The compacting device 3 has a ground surface pressurizing plate 4 and a vibration applying source 5 such as a motor for applying vibration to the plate 4. FIG. 2A shows the state after the first stage of compaction. In the first-stage compaction operation, the ridge 1 is a resin molded product made of vinyl chloride resin or the like, and the plate 4 of the compaction device 3 is directly applied to the ground surface, so the compaction device 3 is too close to the heel 1. Then, the compaction device 3 may collide with the heel 1 and break the heel 1. When two or more ridges 1 are installed and the distance between the two adjacent ridges 1 and 1 is narrower than the width of the plate 4 of the compacting device 3, the ground surface G around the ridge 1 is formed. The compaction device 3 cannot be approached. For these reasons, the first stage compaction operation may not be able to sufficiently compact the periphery of the rod 1. Therefore, in the second stage, as shown in FIG. 2 (B), an annular compacting jig 2 surrounding the persimmon 1 is disposed on the ground surface G compacted in the first stage, and this compaction is performed. The compacting device 3 is placed on the upper surface 2 a of the jig 2, and the ground surface G is compacted again via the compacting jig 2.
[0012]
In this second stage, an annular compacting jig 2 surrounding the periphery of the rod 1 is arranged, and pressure and vibration are applied by the compacting device 3 from above, so that the lower surface of the compacting jig 2 The ground surface G around the kite 1 is pressurized, and can be reliably compacted to the immediate vicinity of the kite 1. Therefore, the pavement (not shown) to be applied to the ground surface G later is prevented from sinking around the fence 1 due to insufficient compaction.
[0013]
Since the portion 2bb extending from the outer peripheral surface to the lower surface is a convex curved surface having a circular arc cross section, the compacting jig 2 has no step between the compacted portion by the jig 2 and its periphery. The periphery of 1 can be strongly compacted. Further, since the compaction jig 2 is made of a polypropylene-based synthetic resin, it can have sufficient strength, hardly changes in quality, has excellent durability, and is easy to manufacture. Moreover, since it becomes lightweight, handling becomes easy.
[0014]
In the above embodiment, the first and second stages of compaction are performed. However, depending on the type of paving and the required quality, the first stage of work is omitted and the compaction jig 2 is used. Only the second stage work may be performed.
Further, the compacting jig 2 may be simply an inverted trapezoidal cross section as shown in FIG. 3 instead of a convex curved surface 2bb extending from the outer peripheral surface to the lower surface 2b as shown in FIG.
[0015]
【The invention's effect】
According to the present invention, there is provided a method for compacting the periphery of the heel by disposing an annular compaction jig surrounding the periphery of the heel with a gap on the outer peripheral surface of the heel on the ground surface where the heel is installed. This is a method of compacting the ground surface from the top surface of the metal by using a compacting device, so that the ground surface around the collar can be compacted without damaging the collar, and even if the spacing between adjacent collars is narrow to some extent. It can be hardened and can prevent pavement from sinking due to insufficient compaction .
