Abstract

PURPOSE:To make it possible to automatically carry out installation work by performing operations of variations between an actual position detected by position receiving sensors loaded to a steel form and a planned position, and controlling motor driven jacks based on them. CONSTITUTION:The rear end of a steel form 1 is installed at existing secondary lining construction bodies 10 and 10. After that, coordinates and sea-level are such that signals are transmitted to position receiving sensors 6 and 6 loaded to the steel form 1 from a position measuring gauge 7 provided to a known measuring point P. Then, an actual positon of the steel form 1 is detected by the receiving sensors 6, and detected signals are transmitted to a measuring operational device. Successively, operations of variations between the actual position of the steel form 1 and a planned position are performed by the measuring operational device, and signals are transmitted to a controller. In the controller, motor driven jacks for horizontal directional and vertical directional movement are controlled, and the steel from 1 is automatically installed at a specific position.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to an automatic control device for secondary lining steel foam.

(Conventional technology) The installation of conventional steel forms for secondary lining requires two surveyors and three to four jack operators, and involves setting the form, pouring concrete, curing, and removing the concrete. Work was carried out in a cycle of mold → movement → formwork set.

(Problems to be Solved by the Invention) The above-mentioned conventional technology requires a large number of workers, and also requires a long cycle time for formwork setting → concrete pouring → curing → demolding → movement → formwork setting. Additionally, there was a possibility of human error occurring during the surveying and machine operations during the installation of the secondary steel foam.

The present invention has been developed in view of the problems of the prior art, and its purpose is to save labor, automatically set the steel form in a predetermined position accurately,
An object of the present invention is to provide an automatic control device for a steel form for secondary lining, which eliminates human errors that occur during surveying and jacking operations, and shortens the construction period.

(Means for Solving the Problems) In order to achieve the above object, the automatic control device for a steel form for secondary lining according to the present invention has a rear end installed in an existing secondary lining structure. a steel form, electric jacks for horizontal and vertical movement mounted on the steel form, a position measuring device installed at a survey point with known coordinate values and altitude in front of the steel form;
a position receiving sensor attached to the front of the steel form that receives a signal from a position measuring device to detect the current position of the steel form; and a position receiving sensor that receives a signal from the same position receiving sensor to determine the actual position and plan of the same position receiving sensor. It is comprised of a measurement calculation device that calculates the deviation from the position, and a control device that receives signals from the measurement calculation device and controls each of the electric motors to hold the steel foam at a predetermined planned position.

(Function) Since the present invention is configured as described above, the rear end of the steel form is installed on the existing secondary lining structure, and a survey point whose coordinate values and altitude are known is placed in front of the steel form. The installed position measuring device sends a signal to the position receiving sensor mounted on the steel form, the receiving sensor detects the actual position of the receiving sensor, that is, the actual position of the steel form, and this detection signal is measured and calculated. Send to device.

The measurement calculation device calculates the deviation between the actual position and the planned position of the receiving sensor, and the measurement calculation device sends a signal to the control device, which controls each of the electric jacks for horizontal and vertical movement. and automatically places the steel form in a predetermined position.

(Example) The present invention will be described below with reference to the illustrated embodiments.

(1) is a second-layer Nisteel foam, with an electric jack for horizontal movement (2) and an electric jack for vertical movement (
3) is installed.

In the figure, (4) is a moving truck on which the same jacks (2) and (3) are mounted, and (5) is a segment.

A position receiving sensor (6) is attached to a predetermined location on the front surface of the steel form ( ).

In front of the steel form (1), a position measuring device (7) is installed at a survey point P whose coordinate values and altitude are known.

Furthermore, the rear truck of the steel form (1) is equipped with a measurement calculation unit that receives the detection signal from the position receiving sensor (6) and calculates the deviation between the actual position and the planned position of the steel form (1), as will be described later. A device (8) and a control (9) that receives signals from the device (8) and controls the electric jacks (2) and (3) are provided.

Is the rear end of the steel form (1) connected to the existing secondary lining structure (10)? After this installation, the position measuring device (7) transmits data to the position receiving sensor (6) of the steel form (1), and the receiving sensor (6) determines the position of the sensor (6), that is, the position of the steel form (1). detects the actual position of and sends a detection signal to the measurement calculation device (8).

In the measurement calculation device (8), the reception sensor (6
) and calculates the deviations △χ, △y, △Z between the actual position and the planned position, and sends a signal to the control device (9), and based on this signal, the control device (9) operates the electric motor for horizontal movement. Jyatsuki (
2) and the electric jack for vertical movement (3), and by automatically controlling the electric jacks (2) and (3), the steel form (1) is positioned at the planned position shown by the chain line.

(Effects of the Invention) According to the present invention, as described above, the position receiving sensor attached to the front part of the steel form whose rear end is installed in the existing secondary lining structure is used to detect the known position in front of the steel form. The current position of the position receiving sensor is detected, and the detection signal is sent to the measurement calculation device to determine the actual position and plan of the position receiving sensor, that is, the steel form. The second layer steel form is automatically controlled by calculating the deviation from the position and controlling each electric jack for horizontal and vertical movement mounted on the steel form with a control signal from the measurement calculation device. By being able to install it more precisely in a predetermined position, the number of personnel required for installation work can be greatly reduced, resulting in labor savings.

In addition, by automatically controlling the installation of the steel form in this way, it is possible to shorten the installation time and shorten the process of secondary lining work, as well as reduce the risk of problems that may occur during surveying and jacking operations. This can eliminate certain human errors.
