Description

[Technical Field]

[0001] The present invention relates to a construction method for various types of construction work on sloping ground such as a mountainside, for example, drilling holes, erecting earth-retaining fences, erecting anchors, erecting piles, and erecting reinforcing bars, and in particular to a construction method suitable for application to steeply sloping ground. [Background technology]

[0002] Construction work on sloping ground (for example, a mountainside) such as drilling holes, erecting earth-retaining fences, installing anchors, installing piles, and installing reinforcing steel bars (hereinafter collectively referred to as "sloping ground construction") requires materials, equipment, drilling machines, cranes, etc. (hereinafter referred to as "materials, etc."), but when the sloping ground construction site is located high up on a slope such as a mountainside (at a high altitude), loading and unloading these materials, etc. is a difficult and challenging job. This becomes even more difficult when the slope is steep.

[0003] Therefore, in the past, when loading and unloading materials on a slope such as a mountainside, (1) Use a mobile (traveling) crane (including large and small). (2) Use a ropeway cable crane. (3) Use a simple cable. (4) Install temporary roads. It was done in the following ways.

[0004] Although it is easy to use a mobile (traveling) crane to load and unload materials, it is not possible to load materials at high places that the crane cannot reach due to the height limit. Also, it cannot be used in places where the crane cannot enter.

[0005] Therefore, the present applicant has proposed a construction method for sloping ground, which involves preparing at least two cranes, setting up horizontal scaffolding in multiple stages on a slope at intervals equal to the reach of the crane booms, using one of the cranes to lift the other crane onto the scaffolding directly above, and then using the other lifted crane to lift one of the cranes on the scaffolding directly below onto the scaffolding directly above, and moving them to the upper scaffold, and using the cranes to lift and / or unload at least materials, etc. (Patent Document 1).

[0006] According to the above construction method, the crane can be moved endlessly upward on the slope, allowing materials to be loaded and / or unloaded upward on the slope, and materials can also be transported by the crane from the scaffolding, thereby achieving the effect of facilitating construction work on slopes. [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Patent No. 3765102 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention aims to provide a method for construction work on sloping ground that makes it easy to load and / or unload materials and the like up the slope without the need to set up multiple levels of scaffolding on the slope in advance, thereby improving the efficiency of construction work on sloping ground and enabling construction over a wide area. [Means for solving the problem]

[0009] In order to solve the above problems, the method of construction work on sloping ground of the present invention is characterized by installing a monorail on the sloping ground, transporting a backhoe using the monorail to install a reaction table, then transporting a stationary crane using the monorail and moving it onto the reaction table, assembling a first jib crane using the stationary crane, assembling a second jib crane above the first crane using the first crane, and repeating this process until jib cranes are assembled above the sloping ground, and using the jib crane to lift and / or unload materials, etc. (Claim 1).

[0010] According to the present invention, there is no need to set up multiple levels of scaffolding on a slope in advance, and materials can be easily loaded and unloaded at the top of the slope without the need for a mobile or large crane, making it possible to improve the efficiency of slope construction work and to carry out construction work over a wide area.

[0011] One embodiment of the present invention is characterized in that the reaction table is an H-steel reaction table (claim 2). According to this embodiment, the reaction table has sufficient strength to stably support a stationary crane and allow construction work to proceed. [Effects of the Invention]

[0012] According to the present invention, there is no need to set up multiple levels of scaffolding on sloping ground in advance, and materials can be easily loaded and / or unloaded from the upper part of a slope without the need for a mobile or large crane, making it possible to improve the efficiency of sloping ground construction and carry out construction over a wide area. [Brief explanation of the drawings]

[0014] An embodiment of the present invention will be described below.

[0015] In the present invention, a monorail M is installed on a slope K. Next, a backhoe 1 and an H-steel reaction table 2 are transported by the monorail M, and the H-steel reaction table 2 is installed by the backhoe 1.

[0016] Next, the stationary crane 3 is transported by the monorail M. Then, the stationary crane 3 is moved onto the H-beam reaction table 2 by the backhoe 1.

[0017] Next, the first jib crane 4 is assembled using a stationary crane 3 stabilized on an H-steel reaction base 2.

[0018] Next, the first jib crane 4 is used to unload materials and the second jib crane 5 is assembled.

[0019] Furthermore, the second jib crane 5 is used to unload materials and the third jib crane 6 is assembled.

[0020] By repeating this process, jib cranes can be assembled above the slope K, and each crane can be used to very easily load and / or unload materials. Furthermore, the jig crane can be used to easily carry out construction work over a wide area. [Industrial Applicability]

[0021] According to the present invention, materials can be easily loaded and / or unloaded on a slope without the need for a mobile or large crane, and there are many applications for this, such as improving the efficiency of slope construction work. [Explanation of symbols]
