Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an all-weather construction method for constructing a mountain retaining wall in the ground and performing underground construction such as root cutting work and construction of an underground skeleton.

[0002]

2. Description of the Related Art Conventionally, in building a building, after constructing a retaining wall on the ground by a retaining wall construction method such as a parent pile side sheet pile construction method or an underground continuous wall construction method, the foundation is cut off to construct the retaining wall. For the purpose of reinforcement, erections, beams, etc. are erected, H-shaped steel is erected on these supporting frame materials, and a lining plate is laid on the H-type steel. He was carrying in a lifting machine for underground construction.

[0003]

However, in the above-mentioned underground work, the work is interrupted when it is raining, and depending on the condition of the root cutting bottom after rain, the underground work may take several days until the soil dries. There was a drawback that it would be interrupted and the construction period would be prolonged.

The present invention has been made in view of the above problems, and an object thereof is to provide an all-weather construction method in which underground construction is not interrupted even in rainy weather.

[0005]

Means for Solving the Problems The object of the present invention to solve the above problems and achieve the above objects is to lay a traveling rail on a mountain retaining wall and attach the traveling rail to a boarding gantry. An extensible temporary roof that is laid across and horizontally opened and closed is movably provided, and a water collecting sheet is laid under the boarding gantry, and a drain hose is provided at an appropriate location of the water collecting sheet for underground construction. It exists in the all-weather construction method.

[0006]

According to the all-weather construction method for underground work of the present invention, the work can be performed without interrupting the underground work by appropriately opening and closing the temporary roof during fine weather or rain. In addition, since rainwater can be treated by the water collecting sheet even on the boarding gantry, it is possible to carry out all-weather construction over the entire range of underground construction.

[0007]

Next, the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing a state of underground construction by an all-weather construction method according to the present invention, FIG. 2 is a front view showing a structure of an end portion of a temporary roof, and FIG. 3 is a collection laid under a boarding gantry. It is a front view which shows the laying structure of a water sheet. In the drawings, reference numeral 1 is a mountain retaining wall, 2 is a traveling rail, 3 is a pedestal gantry, 4 is a temporary roof, 5 is a lifting machine, 6 is an H-shaped steel, 7 is a water collecting sheet, 8 is a girder material, and 9 is a drainage hose. Are shown respectively.

The gist of the all-weather construction method in the underground construction of the present invention is that the construction range of the underground construction surrounded by the mountain retaining wall 1 is completely covered by the temporary roof 4 and the boarding gantry 3.

In the underground construction area surrounded by the mountain retaining wall 1, a loading gantry 3 as shown in FIG. 1 is provided for carrying in the lifting machine 5 in a large-scale construction site. A traveling rail 2 is laid on the mountain retaining wall 1 for each construction area divided by the boarding gantry 3. In this case, the mountain retaining wall 1
Since the upper end of the is uneven in the vertical direction, it is preferable to once lay a pillow material and then lay the traveling rail 2 on it. Then, the traveling rail 2 is attached to the boarding platform 3 in parallel with the traveling rail 2 on the mountain retaining wall 1.

A temporary roof 4 is installed on the traveling rails 2, 2. As shown in FIG. 2, the temporary roof 4 has a roof frame formed by assembling truss members arranged side by side in the horizontal direction, and a sheet member 4a is attached thereon to form a roof. Then, a water collecting trough 4b having a U-shaped cross section for receiving rainwater is suspended at both ends of the roof.

Further, in order to make the traveling rail 2 movable, the traveling mechanism portion 4c having the I-shaped upper portion of the traveling rail 2 sandwiched by the gate shape and having rolling wheels at the contact portions is provided on each roof. It is installed under both ends of the frame. A winch or a motor is used to rotationally drive the rolling wheels of the traveling mechanism 4c.

In this way, the temporary roof 4 can be expanded and contracted in an accordion manner by the flexible sheet material 4a and each roof frame, and can also be moved on the traveling rail 2.

The temporary roof 4 is provided in each of the sections partitioned by the boarding gantry 3. This temporary roof 4
Underground construction is possible even in rain.

Next, in order to perform rainwater treatment on the boarding gantry 3, as shown in FIG. 3, a water collecting sheet 7 is laid in advance on the girder 8 on the supporting frame, and the H-shaped steel 6 is placed thereon. The girder material 8 is erected, and the lining plate 3a is laid on the girder material 8. Then, both ends of the water collecting sheet 7 in the girder direction are folded back upward and fixed to the end edge of the lining plate 3a.

A water draining hose 9 is provided at an appropriate location on the water collecting sheet 7. In this way, since each work area partitioned by the loading gantry 3 is covered with the temporary roof 4, and the water collecting sheet 7 is laid under the loading gantry 3, the temporary roof 4 can be covered with a winch or the like in fine weather. When the vehicle is moved on the traveling rail 2 and opened by the driving means, underground construction is performed, and in case of rain, the temporary roof 4 is extended to close the opening to perform underground construction.

In addition, in the case of carrying in the building materials and the like of the lifting machine 5 in rainy weather, a part of the temporary roof 4 is opened for carrying-in work, and immediately after the carrying-in work is completed, the opening portion of the temporary roof 4 is opened. Should be closed, which does not hinder the underground construction.
Even during fine weather, the temporary roof 4 may be an obstacle depending on the material loading location, but the entire temporary roof 4 may be appropriately moved on the traveling rail 2.

Rainwater that has fallen on the boarding gantry 3 is collected by a water collecting sheet 7 and drained by a water draining hose 9. In this way, the underground construction work can be continued without interruption even if it rains.

[0018]

As described above, according to the all-weather construction method for underground construction of the present invention, the traveling rail is laid on the mountain retaining wall, the traveling rail is attached to the boarding gantry, and the traveling rail is laid across the traveling rail. A retractable temporary roof that opens and closes in the horizontal direction is movably provided, a water collecting sheet is laid under the boarding gantry, and a drain hose is provided at an appropriate location of the water collecting sheet to perform underground construction. As a result, the underground construction can be continued even in rainy weather, and the construction period can be shortened. Moreover, since the temporary roof can be installed by simply laying the traveling rails on the existing mountain retaining wall and boarding gantry, all-weather construction can be performed at low cost. Since the temporary roof is extendable and movable on the traveling rail,
It does not hinder the operation of the lifting machine and can be operated even in the rain, improving work efficiency.
