Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drilling apparatus which is suitable for drilling soil at the time of sampling a soil contamination survey, particularly for drilling a wide range of pavement surfaces such as concrete, stone and asphalt.

[0002]

2. Description of the Related Art In recent years, environmental pollution has become a major social problem. Regarding soil pollution, which is one of the major issues, surveys of various metals and volatile organic compounds contained in contaminated soil have been conducted nationwide. Is in a hurry.

[0003] In order to prepare such a sample for measuring soil contamination, a soil sample or soil gas is collected. These samples are generally collected at some points in the survey area on soil approximately 15 cm below ground level, but it is necessary to drill the surface soil at the site of interest. .

[0004] In particular, when the target site is paved with concrete, asphalt, stone, or the like, a boring device such as a core cutter or a hammer drill is used to drill these paved surfaces. The core cutter is provided with a ring-shaped cutting blade at the tip, and is rotated while supplying cutting water to the cutting blade to bore a pavement surface.

[0005]

A conventional drilling machine such as a core cutter described above has to be manually conveyed and fixed to an object point with anchor bolts. Therefore, the larger the area of the survey section is, the more labor is required. And time are required, and there is a problem that work efficiency is extremely poor.

A conventional drilling machine such as an air cutter requires a power supply for driving. However, since the target site of the soil contamination survey is usually outdoors, it is not easy to secure the power supply.
There was a drawback that power had to be drawn by drawing power lines from telephone poles.

Particularly, in the case of an air cutter, dust is generated when drilling a pavement surface, and it is inevitable that used cutting water is scattered around. For this reason, there is a problem that the soil to be investigated is contaminated by the generated dust and cutting water, and a countermeasure has been desired.

The present invention has been made in view of such a conventional problem, and is applicable to a wide range of outdoor surveys where it is difficult to secure a power source when collecting a sample for soil pollution survey. An object of the present invention is to provide a drilling device that can drill a pavement surface such as concrete or asphalt without contaminating a sample.

[0009]

In order to achieve the above object, a drilling device provided by the present invention comprises: a bogie provided with a traveling means, a core cutter for rotating and drilling a pavement surface; It is equipped with a water supply device that supplies cutting water to the water, a water absorption device that sucks and collects used cutting water from around the core cutter, and a generator as a drive power supply that operates the core cutter and the water absorption device. It is a self-propelled drilling device.

In the self-propelled drilling machine of the present invention,
A caterpillar driven by a motor can be used as the traveling means. In addition, a water-absorbing hose tip of the water-absorbing device can be provided with a scattering prevention cover for used cutting water having an insertion hole through which the tip of the core cutter is inserted.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A self-propelled drilling machine according to the present invention comprises a core provided with a rotatable ring-shaped cutting blade at its tip on a bogie provided with running means such as a caterpillar and wheels driven by a motor. Equipped with a cutter. Therefore, the vehicle can be freely driven by the motor drive and can be easily moved to a predetermined investigation target point, so that efficient drilling work can be performed particularly when the area of the investigation section is large. The running means is not limited, but a caterpillar is preferable in terms of running on sloping ground and increasing the weight of the entire apparatus.

Further, since the self-propelled drilling device of the present invention itself has a considerable weight, it is not necessary to fix the core cutter with anchor bolts as in the prior art, and the drilling operation can be started in a short time. it can. However, in order to reliably prevent the core cutter from shifting or moving from the target point during the drilling operation, it is desirable to equip a fixing plate that presses against the pavement surface and fixes the entire apparatus.

Further, in addition to the core cutter, the bogie provided with the traveling means includes a water supply device for supplying cutting water to the core cutter and a water absorbing device for sucking and collecting used cutting water from around the core cutter. A generator is provided as a driving power source for operating the cutter and the water absorbing device. Therefore, even if the target site of the soil pollution survey is outdoors, or if it is difficult to secure a power source because there are no utility poles nearby, the power can be generated by the generator and the core cutter and water absorption device can be operated. Drilling work can be performed efficiently.

In order to drill a pavement surface with the self-propelled drilling device of the present invention, the core cutter is lowered by a manual or vertical drive while rotating the core cutter, and at the same time, cutting water is caused to flow down from the water supply device. Supply near the cutting blade at the tip of the cutter. By supplying the cutting water, wear of the core cutter can be prevented and scattering of generated dust can be prevented.

Further, since the used cutting water contains dust generated by cutting the pavement surface, it is sucked and collected by a water absorbing device. By equipping the tip of the water-absorbing hose of the water-absorbing device with the scattering-prevention cover for used cutting water, it is possible to collect used cutting water containing dust and dust, eliminate scattering to the surroundings, and recover most of it. . The scattering prevention cover needs to be provided with an insertion hole through which the tip of the core cutter is inserted.

Therefore, by using the self-propelled drilling device of the present invention, it is possible to easily and efficiently use concrete, even in a place where it is difficult to secure a power source such as outdoors, while traveling in a wide soil survey area. It becomes possible to drill a pavement surface such as stone or asphalt. Further, it is possible to prevent dust generated by drilling and used cutting water containing dust from scattering to the surroundings, thereby preventing contamination of soil to be investigated.

And can be moved up and down at an arbitrary distance along the column 6 by operating the handle 7. The core cutter 5 has an upper end connected to a driving motor 8 and can be driven to rotate around a vertical rotation axis. The lower end of the column 6 is a fixed plate 6a, which can be lowered together with the column 6 and pressed against the pavement surface to prevent the core cutter 5 from being displaced.

Further, a water supply tank 9 for supplying cutting water, a recovery tank (not shown), and a water absorption device 10 for a used cutting water provided with a water absorption motor 10b are provided on the carriage 1.
Is installed. The water supply tank 9 is connected to the core cutter 5 by a water supply hose 9a. By opening the valve 9b, the cutting water flows down naturally, and the cutting blade 5 of the core cutter 5
a.

The water absorbing device 10 is provided with a water absorbing hose 10.
a extends in the direction of the core cutter 5, and a scattering prevention cover 11 is attached to the tip of the water absorbing hose 10a. The scattering prevention cover 11 is provided with an insertion hole 11a through which the lower end of the core cutter 5 that moves up and down can be inserted. Therefore, the cutting water supplied from the water absorption tank 9 to the core cutter 5 is collected almost without leaking out of the scattering prevention cover 11, is sucked by the water absorption hose 10a, and is collected and stored in the collection tank of the water absorption device 10.

The motor 8 for driving the core cutter 5
The water absorption motor 10b of the water absorption device 10 is operated by electric power supplied from an engine generator 12 provided on the truck 1.
