[Industrial applications]

 The present invention relates to a boring rod supporting mechanism integrated with a boring machine for boring, and more specifically, to a technology in which a boring rod supporting mechanism is integrally provided on a boring machine for boring.

[0002]

[Prior art]

 As is well known, in the geological survey, chemical injection hole construction, simple pumping well construction, landslide prevention construction, etc., there are many cases of drilling the ground by boring. The machine used at this time is a boring machine for boring. The boring machine for boring has a chuck portion for holding the boring rod, and the boring rod is dug into the ground with the boring rod standing vertically.

Incidentally, the boring rod is often dug deep into the ground, and its length is relatively long. When the relatively long boring rod is sandwiched only by the chuck of the boring machine for boring and is intended to stand vertically, it is difficult to stand vertically due to the inclination of the boring rod due to its own weight.

Therefore, conventionally, in order to hold the boring rod vertically, a vertically extending main pillar, one end thereof is axially supported by the main pillar, and the other end thereof is axially connected to one end of the second supporting pillar. A so-called yagura was used, which was composed of a first support and a support composed of the second support. More specifically, the other end of the main pillar is fixed to the ground, and the other end of the second support pillar is also fixed to the ground to erect the main pillar. Furthermore, one end of the main pillar is prevented from falling. The rope was fixed to the main pillar and the other end was fixed to the ground, and the rope was fixed using the wire rope stretched. That is, the boring machine for boring and the yagura were separate bodies, which were separately transported and installed.

[0005]

According to the above-mentioned conventional technique, there are some problems in the following points. That is, firstly, it is necessary to separately load and unload both the boring boring machine and the yagura during transportation because the yag must be prepared separately from the boring boring machine. There was, and it was troublesome. Secondly, when the boring machine for boring and the yagura are installed, after first installing the boring machine for boring, the main pillars and columns of the yagura are installed at predetermined positions around the boring machine for boring. It was time-consuming to fix the other end and to set up the tower. Thirdly, by installing the above yagura around the boring machine for boring, the area of land necessary for performing the boring work is in addition to the area occupied by the boring machine for boring. The area occupied when the above tower is set up is also necessary. However, there are places where it is difficult to take a large work area due to various factors at the actual site, and it was required to take a work area corresponding to the above-mentioned relatively small land. Fourthly, in relation to the third problem, in order to install the boring machine for boring and the yagura, it is necessary to have a flat land on which the boring machine for boring and the yagura can be installed. However, this is also difficult to secure at some sites, and there has been a demand for technology that enables excavation work even in relatively narrow flat areas.

Therefore, an object of the present invention is a machine for supporting a boring rod which is to be excavated by the boring machine for boring, and firstly, the boring machine for boring. It is also possible to load and unload together, and to simplify the loading and unloading work. Secondly, apart from installing the boring machine for boring on the ground, it is necessary to install a machine for supporting the boring rod on the ground. The whole installation work can be done easily without it. Thirdly, the land area for installing the boring machine for boring and the machine for supporting the boring rod is relatively small, and fourthly, The purpose of the present invention is to provide a technique capable of excavating work by using the boring rod without taking a large flat area for installing the boring machine for boring.
