Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for excavating a vertical hole in the ground surface, which is used when excavating a vertical hole such as a pilot hole for a large manhole in the ground.

Conventionally, diameter 2. When excavating a 5m vertical hole in the ground surface (hereinafter referred to as a ground hole), a self-propelled excavator is placed on the bottom to excavate the earth and sand, and the excavated soil is lifted to the ground surface using a lifting device. However, since the traveling vehicle body that serves as the support for the excavator has a large bottom and occupies a relatively large space, if the traveling vehicle body is not moved, it will be difficult to move the packets at the tip of the boom or the air play car. The excavation work area is narrow, and in order to excavate every corner of the bottom, the vehicle must be moved forward and backward frequently, and the presence of the traveling vehicle makes it difficult to use soil evacuation equipment, ventilation equipment, ladders, etc. The auxiliary working space for setting up materials and moving them up and down is also small, making the overall excavation work inefficient.

The present invention was provided in view of the drawbacks of the above-mentioned conventional examples.The present invention has a large to++ working range of a power excavator, a large working space for various materials around the working machine, and a safe ground with good working efficiency. The purpose of the present invention is to provide a method and device for drilling a vertical hole.

It is designed to be driven into the bottom of the hole.

A second embodiment of a method for excavating a vertical hole in the ground using the sound of the above-mentioned equipment will be described. First, as shown in FIG. 6 <a>, a trench 50 having approximately the same diameter as the diameter of the dirt storage cylinder A is dug in the ground using a shovel. Then, as shown in FIG. 6(b), the lower half of the cylinder A is fitted into the prepared hole and fixed to the ground 51. In this state, the upper and lower ends of both ends 14a of the support beam 0 are clamped by stopper pins 11 inserted into the highest pin holes 9, 9 of the guide rail B. In this way, the entire operation of the device is started from the ground. First, the vertical frame D is appropriately lowered by the locked cylinder 19, and the crawler F is moved to the Taisei 50f.
The cylinder is stopped at f, and the vertical frame D is fixed to the solid shaft 15 by the parallel link 18. Next, the rod 48af of the hydraulic cylinder 48 is extended and the technical part 46 is inserted into the soil of 50σ to fix the lower end of the vertical frame D to the ground. If you do T like this,
During excavation, the horizontal reaction force acting on the packet 24 is counteracted by the crawler r and the technique section 46, and the vertical reaction force of the packet 24 is counteracted by the weight of the device itself, so that no large force is applied to the ground from the cylinder frame A. . In this way, power shovel E1! i'' Excavate the bottom of the hole in front of the vertical frame D using hydraulic pressure, and discharge the earth and sand to the ground using a lifting device (not shown). After this excavation, the packet 24 of the power shovel 1 is lifted up by the Taisei 507, and the cylinder 48 is raised, the technical part 46 is removed from Taisei 5oa, the cylinder 19 is freed, the fixation of the parallel link 18 is released, the crawler F1 is run by the hydraulic motor 45, and the vertical frame D is moved to the center of the solid shaft 15'l. It is rotated a certain distance along the inside of the cylinder frame A as Ω-shira 1!
Stop. Then, like last time, we fixed the parallel link 18, drilled it into the 46'Ft hole bottom 5oa, and used the power shovel E to excavate 50tf in front of the vertical frame D and remove the soil. If the entire surface of Taisei 50a is excavated in this way and the distance between bottle holes 9 and 10 is approximately how deep, then,
The vertical frame Dk is lowered by the cylinder 19, the crawler r and the packet 24 are placed directly below the support beam C, the pin 11 is removed from the bottle hole 9, and the support beam C is lowered by the cylinder υ. As shown in 0), the pins 141i and 141i are placed between the pin holes 10 of the next stage, and the pins 11 are inserted into the same pin holes and fixed to the support beam a2 guide rail B, and the entire bottom is excavated in the same manner as described above. In this way, when the support beam 0 is fixed to the pin hole 1Oa at the final stage of the guide rail B as shown in FIG. 6(d) and the bottom is excavated, the bottom is excavated as shown in FIG. 6(, ). Raise the vertical frame D and raise the excavator I appropriately, attach a new short cylinder frame L to the top of the cylinder frame A, and lower the entire cylinder frame A into the ground hole as in method 1. lower to Thereafter, the bottom is similarly excavated, the short cylinder frame 1 is joined to the cylinder frame A, and the subframe A'l is lowered, and when the ground hole reaches the desired depth, the support beam 0
Meeting Vertical Frame D, Crawler! , the power shovel E1 and the guide frame rail B1 bracket) 4'J5A are pulled out of the ground, and as shown in FIG.

In the above work, if there is concrete etc. at the bottom,
An air play car tool is attached to the back of the packet 24 to crush it.

In addition, in the apparatus used in the above construction method, the arms 14 of the support beam C can be replaced depending on the length and length of the legs and the inner diameter of the cylindrical frame A. Accordingly, the length of the parallel link 18 is also changed β. In addition, the crawler ν may be a simple wheel, and the solid shaft 1
5 may be applied to rotate the vertical frame D. Furthermore, the support beam C is not limited to one extending in the diametrical direction of the cylinder frame A, but may be three or four supporting beams extending radially from the center.
It should be shaped so that the arms stick out.

The method of the present invention is as described above, and since the Taisei power shovel is operated from the ground, the work is safe.
In addition, since the general ground above the excavated area is filled with soil using a cylindrical frame, there is no ground collapse. A large space is created between the supporting beam and the cylindrical frame, which has a wide range and is a vertical frame, making it easy to perform tasks such as transporting earth and sand, and guarding the loading and unloading of materials.
When there is rock at the bottom and blasting work is to be carried out, the removable support beam can be lifted from the ground to raise the vertical frame and the main parts of the power shovel equipment to an appropriate height as a shelter wall. Overall, it is safe and easy to work with, and by attaching a short cylindrical frame to the top of the cylindrical frame and digging while sinking like a submerged box, and removing all the support beams, vertical frame power excavators, etc., a large diameter deep hole can be created in the ground. It has the feature of allowing holes to be drilled freely.
