Description

Perpendicularity Measuring Instrument for Boring-Grouting}

The present invention relates to a device capable of accurately measuring in real time the verticality of boring-grinding balls or structures formed in the ground during boring-grinding operations.

In general, the boring-grinding method is a method that is implemented for reinforcement, etc., when the danger of safety of buildings or structures due to the degree of preventing water inflow, reinforcement of soft ground, and ground subsidence causes danger to safety. Through the hole (boring-groting ball) to a predetermined depth through the grout material (Grout 등) or the like while stirring or mixing the ground soil and the chemical solution while solidifying by solidification by stirring and mixing.

This boring-grinding method is constructed by using a device equipped with a stirring blade and a boring bit on the lower part of the boring-grinding rod connected to the leader supported by the base machine with a swivel joint. It consists of a penetration step of drilling and a drawing step of supplying grout material to the inside of a boring-groting ball, or the step of solidifying the soft ground by stirring and mixing the ground soil and the solidified chemical liquid at the same time as the penetration and stirring while drawing. It consists of, the boring-grinding rod is formed with a cavity for injecting compressed air or a cavity for injecting compressed air to disturb the ground.

However, in the construction of the boring-groting method, the perforated direction is inclined or the structure formed in the ground is inclined due to inhomogeneity or mechanical vibration of the perforated soil, and the perforated direction or underground There was an attempt to work by measuring the verticality by installing a transmitter that measures and transmits the verticality by the angle sensor to the head of the reader to make the structure formed in the vertical. However, since the head of the reader is fixed, Although the slope of the boring-grinding rod, which is a part that is inserted into the ground, is not accurately reflected for the work of forming the structure, the effectiveness is insufficient, and although this may be a secondary work, the boring-grinding ball or underground To conduct a vertical view of the structure formed on the Since there was no device to measure accurately with the liver, the construction site had to solve this problem by relying on empirical methods such as adjusting the drilling speed according to the softness of the ground, and thus had a problem of excessive time and cost input.

The present invention is to solve the above problems in the boring-grinding method, it is perpendicular to the ground by measuring the vertical degree of the boring-grinding ball or the structure formed in the ground in real time and accurately to the operator The purpose of the present invention is to prevent boring holes and allow efficient construction by forming boring-grinding balls or underground structures.

In order to achieve this purpose, the verticality measuring device of the present invention includes a verticality measuring instrument mounted on the lower end of the angle measuring cavity formed inside the boring-groting rod, and a transmitter for transmitting the measurement data received from the verticality measuring instrument. In addition, the measurement data transmitted from the transmitter is composed of a verticality indicator for receiving, displaying and printing at the place where the operator is located, characterized in that to determine the verticality of the structure to be formed in the boring-grinding ball or underground in real time .

The configuration of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 to 4, the boring-grouting verticality measuring device of the present invention includes a solid material injection cavity 8a or compressed air injection cavity 8b inside the boring-grouting rod 4. Is a verticality meter (9) fixed to the lower end of the angle measuring cavity (8c) formed separately and the verticality indicator (17) where the transmitter 13 and the operator are located in the head 14 of the reader (2) The vertical measuring instrument 9 and the transmitter 13 are angle measuring cavities 8c formed in the boring-grouting rod 4 through inlets 15 formed in the swivel joint 3. It is connected to the data cable 12 is inserted into the, the angle measuring cavity (8c) is to insert the vertical measuring instrument (9) and data cable 12 therein through the entire boring-groting rod (4) It is formed in sufficient size.

The vertical degree measuring instrument 9 is equipped with an angle sensor 10 and a sensor signal processing unit 11 therein, and the angle sensor 10 is formed in the slope or ground of the boring-groting ball 7 to be drilled.
