In the construction work, the drilling work for piling and piling is essential during the foundation work of upper structure. If the basic requirements are satisfied by the improvement of pile quality and the development of equipment, the failure rate of driving work is very low. That is, if the correct working position is preceded by the attitude and precision survey of stable horizontal work of the equipment, it is possible to perform the fine work.

However, it is difficult to select the exact work site and maintain the verticality of the equipment because the construction is performed on uneven ground on the unstable ground due to the condition of the work site. Since the verticality of the driven file or the punching equipment cannot be expected, the process of continuously checking and calibrating the verticality is repeated and recorded while observing various data.

Although the automatic measurement method has been registered in the patent (Notice No.1995-0004586), it is an obsolete sensor that detects the angle of the file with severe vibration and shock.It can capture the tilting direction but cannot quantify the error. It could not be applied to the construction that requires precise construction of the product.

It is most desirable to ensure the flatness of the ground on which the work is performed.

In order to ensure the flatness and to observe and record the accurate and continuous phenomena of files and perforated casings with high vibration and impact, non-contact measurement should be performed to minimize the confusion caused by direct vibration or impact. You need the ability to take action.

This invention is to measure and record the inclination and the length of the driving direction of the driving and drilling in pile driving equipment and drilling equipment to improve the quality of the driving and drilling work. Designed for displacement measurement and recording device (also called MPD system) of pile driving and drilling work, which consists of controller for data processing, pile or drilling casing remaining on the ground in pile driving equipment and drilling equipment (A) Displacement measuring device consisting of a distance measuring device for measuring the degree of displacement of the vertical axis of the central axis of the axis, and a rotation speed measuring device for measuring the studded length and the spatter length of the pile or perforated casing, and for every input entered through the previous measuring devices. Input data such as studded length, splatter length, number of hits in intervals, etc. It consists of a controller that calculates, displays, records, and generates a working daily distance from the casing in real time, enabling accurate site quality management and construction data analysis and review.

According to the drawings

1 is a diagram for performing a non-stop hit of the pile driving method using a crane as the equipment (A).

The hammer is suspended from the work piece (E) on the work piece (E) with the required symbol (D) drilled through the work hole (F) by precisely surveying the drilled target site by precisely measuring the drilling target to maintain the stable posture of the equipment. C) The figure is in motion with the file 10, the measuring device of the present invention is not shown.

2 is a perspective view and an enlarged view of a main part of the displacement measuring apparatus 20 as an example of the present invention.

The two triangular frames equipped with measuring devices are connected by a height-adjusting column to form a triangular bar, which is fitted to the pile 10 and fixed to the floor E. Depending on the site conditions, it may be fixed to the equipment (A) via connecting rods.

 The inside of the circle on the upper right is a cross-sectional view of the upper triangular frame 21 from above. Each side of the upper triangular frame 21 is provided with a light wave distance measuring device 23 having a generational reflector plate 24. Each side of the triangular frame 22 is provided with an optical wave range measuring device 23 having a reflector plate 24 of a generation and two rollers 32.

The triangular frame is preferably a regular triangle, but may be modified according to the conditions of the workplace.

Since each light wave range meter and the distance to the center line 13 of the pile when the pile is standing vertically are the reference for measurement, the irradiation direction of the light wave is accurately aimed at the center line 13 of the pile at the initial stage of driving. You must put it. Measurement is possible even without the reflector 24, but the measurement accuracy can be improved by using a reflector made of a color or reflector material suitable for the characteristics of the light wave.

The reflector should always be supported by a spring or shock absorber so that it is against the surface of the pile to mitigate the impact.

The lower triangular frame 22 is close to the point 11 where the pile starts to enter the ground, so the displacement is insignificant and can be corrected by an internal program. Therefore, the installation of the optical wave range meter may be omitted.

The picture inside the ellipse at the bottom right is a detector that measures the studded or spatter length. It is equipped with a roller (32) made of a wide and elastic material and a rotary rotary encoder (33) on the same shaft as the roller, and is supported by a connecting rod (34) equipped with a spring or shock absorber so that it always rests on a pile. .

The studded length measuring device 31 calculates only a signal when turning clockwise, and the bouncing length measuring device 32 takes only a signal when turning counterclockwise.

3 is a principle diagram for deriving a slope by detecting a displacement of a pile.

If the r value is obtained when the displacement of the height of l is measured in the pile of length L, the displacement of the top end 12 becomes R, L / L times r.

In other words, tan (tilt angle) = R / L = r / ℓ can know the tilt angle.

L is the length remaining on the ground of the pile piled up continuously and R is the distance to know the position of the center point 12 at the top of the pile in response to the ever-changing L, to help the supervisor or worker understand the phenomenon and Make it easy to correct your posture.

The figure in the circle on the left shows an example of the location of the center point at the top of the file on the monitor screen. The outermost circle (a) is a circle representing the limit of tolerance for length L in terms of length, and the inner circle (b) represents the limit of tolerance for L at the measurement point in terms of length. The circle (c) of the small circle indicates the current position of the center point 12 at the top of the pile.

4 is a block diagram showing the configuration of a title apparatus.

Signals generated by the respective measuring instruments 21, 22, 30, and 31 are input to the signal conversion device 41.

The controller 40 operates a signal converter for transmitting data, a keyboard 42 for inputting any necessary data, a remote controller 43 for easy operation of the controller, a memory 44 for storing data, and computes processed data. It consists of a monitor (45) to display the processed data, the printer and recorder (46) to output the processed data, and a warning light and a rich man (4) to generate a warning when the displacement exceeds the reference value. do.

 The MPD system described above can automatically record and save the work status such as driving length, driving length, splatter length, and slope of the m recovery file, and can be always output to monitor and recorder / printer. It is easy to analyze and review on-site quality control and construction data. In addition, the MPD system can compare the initial reference value and the detected data and output an output signal 48 that corrects the posture of the lid, file or casing as necessary.

 Workers or managers can accurately grasp the work progress and perform reliable construction. Even during busy work, it can prevent poor construction through the pre-warning device, and record the precise work process.
