In addition, the linearity of the expansion girder 11 is enhanced with a winch or a support wire and a tent 13 is swelled by way of a compressor 42 and an air pipe 13a where a blind curtain 41 is lowered to a desired elevation so that it may serve as a wind and rain shelter. Dam concrete is placed or rolled up under the roof 10 and cured after the execution of work is over.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-propelled roof device for all-weather construction, which is suitable for construction of a large structure such as a concrete dam, particularly when it is used in construction in rainy weather. Is.

[0002]

2. Description of the Related Art Dams known as giant structures are
It is constructed as a structure that creates a reservoir for water use or flood control such as power generation, flood control, irrigation, water supply, and industrial water. It is roughly classified into concrete dams and fill dams according to the materials used. In addition, concrete dams are classified into arch dams, gravity dams, hollow gravity dams, buttress dams, etc. according to their structural type, and fill dams made by stacking soil materials and rocks are of uniform type, zone type, surface impermeable type, etc. It is classified.

In order to construct a dam which is such a huge structure, for example, in a concrete dam, a plurality of horizontal joints orthogonal to the dam axis are provided, and a region divided by these horizontal joints is used as a block unit. Layer system construction method in which concrete is sequentially placed and constructed
Or, it is constructed by the block system construction method in which a vertical joint is provided.

[0004]

By the way, since the construction of a huge structure such as a dam is carried out in the open air,
During the construction period, it is often affected by the weather, and especially when the rain continues for many days, the process is often significantly delayed. Since the delay in the process directly affects the construction cost, it has been strongly desired to develop a construction method which can be carried out regardless of the weather.

In particular, when constructing a structure such as a concrete dam having a wide area (area) for placing concrete, it is not possible to cover it with a sheet or the like each time it rains. However, the concrete pouring work had to be interrupted or abandoned, and in any case, it was necessary to develop a construction method that could be used even in the rain.

Here, as a method for pouring concrete in rainy weather and curing the concrete after pouring, a temporary roof for the rain can be constructed to cover the construction range at the construction site, and an assembling tent is used. A method of standing up is also conceivable, but installing such a temporary roof and tent over a fairly wide range has a problem of enormous labor and cost, and moreover, it is dismantled every time concrete is driven to the upper stage. In addition, assembling work is required, and there is a problem that the conventional method of waiting for the recovery of the weather is more advantageous.

The present invention has been made in consideration of the above points, and in the construction of large-scale structures such as dams in the open-air, especially in the case of rain, concrete pouring and curing are common. Not only can work be performed, but the roof can be easily moved according to the transition of the construction area, enabling a wide range of construction, which makes it possible to realize a construction method that is not affected by the weather and reduce construction costs. The present invention aims to provide a self-propelled roof device for all-weather construction.

When moving, the moving direction is set to 90
When it becomes necessary to change the direction, the state shown in FIG.
As shown in FIG. 4, the jack 32 of the direction changing device 33 is operated to levitate the vehicle body 34, and the vehicle body 34 is rotated 90 degrees as shown in FIG. 4 (c2), and then the jack 32 is housed and the vehicle body 34 is lowered. You can change the direction by doing so. By doing so, the direction of movement can be changed by in-situ rotation. Of course, since the direction can be freely changed within 90 degrees, for example, the direction can be changed to 60 degrees or 45 degrees, it is practically possible to move in any direction of 360 degrees by in-situ rotation. In addition, as a matter of course, the caterpillars 3 on both wheels of the lift car 30 are in the middle of traveling.
It is also possible to adjust the traveling direction with 1, 31.

As can be understood from these drawings, the four support mechanisms 20 of the roof 10 are configured to be expandable / contractible in the height direction. It is also possible to install it in a stepped position which is the adjacent blocks B2 and B2 on the left and right while straddling the construction block B1.

As described above, in the self-propelled roof apparatus for all-weather construction according to this embodiment, not only the construction method which is not affected by the weather can be realized to save the construction cost, but also the movement to any position is free. Flexible, "Freely adjustable to any height, # can be installed in different places, $ tent has no rain pool,% rain blowout is shut out, & temporary equipment for fixing is not necessary The effect of will be obtained.

In addition, although the example applied to the self-propelled roof device for the construction of the concrete dam by the layer construction method is shown in the embodiment, the concrete dam by another similar construction method or another type of dam, or another type of dam.
