Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a construction machine for a fill dam that is constructed by stacking earth, sand, gravel, rocks, and the like.

In particular, the present invention relates to an improvement of a self-propelled paving machine for constructing an asphalt center core in a so-called center core type fill dam in which an impermeable wall made of an asphalt core is provided in the center of the dam.

(Prior Art) As shown in the cross-sectional view of FIG. 9, a center core type fill dam is sandwiched with crushed stone layers B and B on both sides of a core made of an asphalt mixture layer A having a water blocking function. It is constructed by stacking earth and sand, gravel, and other rocks on both sides in a bank.

By the way, conventionally, when constructing this asphalt center core C, asphalt mixture layer A and crushed stone layers B and B on both sides are fixed as shown in FIG. 10 on the foundation along the construction line of the fill dam. It is common to lay in parallel with widths A ', B', B'and height H ₁ and stack them in order from the bottom up to the top height of the dam. .

That is, zones B ', B'for paving the crushed stone layers B, B on the foundation on which the asphalt center core should be built in advance.
And a zone A'for paving the asphalt mixture are set in advance, and the crushed stone layers B, B and the asphalt mixture layer A are piled up on the zone A'for construction.

Moreover, the paving work is generally performed by a crawler type so-called self-propelled paving machine. By the way, the first
FIG. 11 and FIG. 12 show a conventionally used asphalt center core self-propelled paving machine. As shown in this figure, a conventional self-propelled paving machine is provided with a crushed stone material hopper 1 for accommodating crushed stone material for constructing a crushed stone layer B, B at the front part (left side in the figure) of a crawler type traveling vehicle. The asphalt mixture hopper 2 which is the material of the asphalt mixture layer A is mounted on the rear part of this, and the crushed stone material and the asphalt mixture supplied from the hoppers 1 and 2 onto the roadbed are spread on the lower part and the rear of the asphalt mixture hopper 2. The flattening device 3 and, finally, a compaction device 4 for compacting and compacting them are equipped in a traction system.

To further explain the configuration of this point, first, the crushed stone material stored in the crushed stone material hopper 1 is set on the roadbed by the bar feeder 5 provided at the bottom of the hopper 1 shown in the plan view of FIG. Left and right paving zones B ', B'on both sides
To be supplied to. Therefore, as shown in the plan view, the bar feeder 5 is equipped with a double type that is parallel to the traveling direction of the pavement machine and can be distributed and supplied to the left and right pavement zones B ', B'on the roadbed.

Next, the leveling device 3 for leveling the crushed stone material supplied on the roadbed makes it possible to adjust the leveling thickness.
As shown in FIG. 10 and FIG. 12, the level of the lower end edge 3 ′ of the leveling device 3 is vertically adjustable by the hydraulic support 6.

The hopper 2 for containing the asphalt mixture is provided with a discharge port 2a at the lower part, and from the discharge port 2a, between the crushed stone paving zones B'and B'laid by the leveling device 3, that is, FIG. The asphalt mixture is constructed so that the asphalt mixture can be dropped into the asphalt mixture pavement zone A '.

Next, the compaction device 4 for compacting the crushed stone material and the asphalt mixture material supplied to the crushed stone material pavement zones B'and B'and the asphalt mixture material pavement zone A'includes three vibration type compaction machines 4a and 4b. , 4b are arranged in parallel to form a triple structure, and as shown in FIG. 12, they are connected so as to be pulled by an arm 7 projecting rearward from the vehicle frame. That is,
As shown in the plan view of FIG. 12, crushed stone material pavement zones B ′ and B ′ and intermediate asphalt compound material pavement zones A ′ on the left and right sides of the traveling direction of the paver are respectively provided in the triple rolling device 4. The compaction machines 4b, 4b and 4a are designed to perform compaction at the same time.

Next, a description will be given of the procedure for concretely performing the paving work using this self-propelled paving machine. First, the pavement machine is arranged so that it can travel along the pavement design line of the asphalt center core C at the dam construction site. And Figures 10 through 12
The pavement machine is run along the pavement design line shown in the figure, and the crushed stone material pavement zones B ', B'with a constant width, the asphalt mixture pavement zone A', and a layer with a certain thickness H ₁ are piled up to crush stone material. The layers B, B and the first layer of the intermediate asphalt mixture layer A are first paved.

In the following, the pavement machine is run on the planned line of the previous layer which has already been paved in the above manner to hierarchically build the crushed stone material layer and the asphalt mixture layer up to the top position of the dam.

(Problems to be solved by the invention) By the way, in the paving work by the conventional self-propelled paving machine described above, there were the following problems.

First, the first point is that the structure of the leveling device 3 that supplies crushed stone material from the hopper 1 to the crushed stone material paving zone B ′, B ′ through the bar feeder 5 and spreads the supplied crushed stone material is a plate. Since the sheet-shaped leveling plate is simply extended laterally, the crushed stone material is not sufficiently dispersed in the parts located outside the pavement zones B'and B ', and the pavement width is made uniform. There was a drawback that could not be regulated. Therefore, the leveling device 3
The actual situation is that a worker is attached to the rear of the building and each paving worker performs correction work.

As a result, it not only causes a decrease in the efficiency of the pavement work itself, but also causes unevenness in the compaction of the pavement zones B ′, B ′ during compaction compaction of the next layer, which reduces the function of the impermeable wall after construction. I was worried.

The second point is that the hopper 2 that holds the asphalt mixture is installed in a fixed form on the vehicle frame that constitutes the paving machine, so the lower discharge port of the asphalt mixture hopper 2 is on the pavement surface (roadbed surface). On the other hand, there is a drawback that the level cannot be adjusted, and therefore the pavement thickness of the asphalt mixture cannot be appropriately selected and adjusted.

Especially, the effect is that when the asphalt mixture is layered up to the top of the dam and paved, a gap is created between the surface of the already paved part and the lower discharge port of the asphalt mixture hopper 2. Foreign matter other than the mixture is mixed, which is a factor that deteriorates the quality of the paved asphalt layer.

Next, as a third point, the compaction device 4 for finally compacting and compacting the crushed stone material and the asphalt mixture, and the crushed stone pavement zones B ′ and B ′ shown in FIG. 12 and the intermediate asphalt mixture. The paving zone A'consisting of the material layer A is configured to be simultaneously compacted by the triple compaction compaction device 4, and the compaction device 4 is connected to the arm 7 projecting rearward from the vehicle frame. However, since it is configured to be pulled, the bottom rolling surface of the rolling device 4 does not come into surface contact with the rolling surface, but tends to come into line contact, and it is difficult to uniformly apply surface pressure. As a result, there is a drawback that it is impossible to expect a uniform and efficient rolling compaction effect.

After the completion of other paving work, when the paving machine is transported from the site to a factory, for example, if there is residual asphalt mixture used in the asphalt mixture hopper 2, it will fall down from the hopper 2 during transportation and There were drawbacks such as the loss of material and the difficulty in clearing the marks.

This invention eliminates the drawbacks of such conventional paving machines,
It is intended to provide a paving machine having higher functionality and higher economic efficiency.

(Means for Solving the Problems) As means for achieving the above object, the present invention provides a crushed stone material hopper, which is connected to the crushed stone material hopper, from the front portion to the rear portion of a self-propelled vehicle, and on both left and right sides of a roadbed. In the crushed stone material paving zone, a bar feeder for supplying the crushed stone material, a leveling device for laying the supplied crushed stone material, and behind it, an asphalt mixture located between the left and right crushed stone material paving zones. The asphalt mixture hopper that supplies the asphalt mixture is sequentially installed in the pavement zone, and further behind it, the triple-rolling compaction device that compacts and compacts the crushed stone material pavement zone and the asphalt mixture pavement zone. In a self-propelled paving machine for an asphalt center core in a fill dam, which is formed by connecting an arm to the rear of the vehicle frame, At the bottom of the vehicle between the mouth side and the leveling device, a partition plate for separating the left and right crushed stone material pavement zones and the asphalt mixture pavement zone is equipped, and the crushed stone material pavement is provided on both sides of the leveling device. In addition to mounting the end plate that regulates the width of the zone, the entire leveling device is installed so that the height position can be adjusted vertically with respect to the vehicle, and a shutter gate is installed at the lower discharge port of the asphalt mix hopper. attachment,
In addition, partition plates are installed on both sides of the lower discharge port so that the entire asphalt mixture hopper can be supported vertically with respect to the vehicle, and a triple rolling device is extended rearward from the vehicle frame. In addition to connecting the adjustable height position to the arm, a partition plate is installed between the central compactor and the compactors on both left and right sides of the compactor, and the lower part of the central compactor is heated. It is characterized in that the device is incorporated.

(Operation) Since the self-propelled paving machine for asphalt center cores in the fill dam according to the present invention is configured as described above, it is necessary to load and build each material on the crushed stone material hopper and the asphalt mixture hopper. When the machine is run along the roadbed on the planned line of the asphalt center core in the fill dam, the asphalt center core can very efficiently pave the center core excellent in quality function as a water blocking wall.

That is, first, the crushed stone material hopper travels while supplying the crushed stone material to the crushed stone material paving zone through the bar feeder. At that time, since the partition plate that separates the crushed stone material pavement zone and the asphalt mixture pavement zone is equipped between the outlet side of the bar feeder and the next leveling device, the crushed stone material will be the asphalt mixture material. It doesn't get stuck in the pavement zone. That is, they are supplied in an orderly manner.

Next, the crushed stone material supplied is evenly spread by the next leveling device. Since the end plate is attached to the outside of the leveling device, the crushed stone material can be leveled evenly over the entire width of the paving zone. Moreover, since the entire leveling device is mounted on the vehicle frame so that the level in the vertical direction can be adjusted, the pavement thickness can be set arbitrarily by adjusting this level.

Next, in the middle of the crushed stone material laid down about the running of the vehicle,
Asphalt mix is supplied. Since the asphalt mixture hopper that supplies the asphalt mixture is equipped with partition plates on both sides of its lower discharge port, the infiltration of the asphalt mixture into the crushed stone material paving zones on the left and right sides is eliminated, and so-called impermeable Form the center core as a layer.
Then, the crushed stone material and the asphalt mixture respectively supplied to the crushed stone material pavement zone and the asphalt mixture pavement zone were finally tightened by a triple rolling device connected to the tail of the vehicle as the pavement machine was running. Hardened. At this time, since the triple rolling device is connected to the arm projecting to the rear of the vehicle in a form capable of adjusting the height position, the rolling surface of the rolling device is effective in advance against the paving surface. If the connecting height position is adjusted and connected so that a proper rolling action can be provided, that is, the pulling is performed in the form of surface contact, the respective materials are rolled very effectively. Will be.

As can be understood from the above description, the self-propelled paving machine according to the present invention can automatically pile up the asphalt center cores by reciprocating on the pavement design line of the asphalt center cores. In particular, it is possible to economically and efficiently construct a high-quality asphalt center core as an impermeable wall of a fill dam.
