Description

Construction data control device for ground improvement and geological surveys {The control system of construction data}

The present invention relates to a construction data control device such as soil improvement method and geological survey, and the drilling load, the drilling time, the rotation of the rod of the hydraulic line of the spindle during the drilling work boring machine to the planned depth to create the modified column Records and outputs the rotational speed, drawing interval, drawing time, etc. of the rod in the process of drawing the rod while generating a modified column by spraying high-pressure fractionation from the tip of the rod after completion of drilling. The present invention relates to construction data control devices such as geotechnical improvement methods and geological surveys to improve the quality of future construction by identifying the ground situation and using it for actual construction of site-based refined stocks, and at the same time as a database of construction know-how. .

An example of the conventional high pressure injection method of the conventional ground improvement method is spraying fresh water to the planned depth and adjusting the timer when drilling is completed to change the rotational speed of the rod to a low speed of 4 to 6 rpm to set the construction state, and the motor rotation of the high pressure pump When the injection pressure reaches 50Kg / ㎠ and the injection pressure reaches 50Kg / ㎠, the high pressure injection is started while the injection pressure starts to be 200Kg / ㎠, and the rod is drawn while generating the modified liquor. The refinery should be constructed until the upper limit of the injection is planned.

In the conventional high-pressure jet injection method, the depth measurement up to the depth of the plan was determined by counting the number of rods required for drilling, and the length of one rod x the number of rods. The rotational speed was not measured by the number of revolutions, but the rotational speed was judged by the correlation with the hydraulic pressure applied to the neck or by the boring machine. Only load was measured.

Therefore, the conventional high pressure injection method does not measure accurate construction data, cannot use the data from the previous process in a later process, and cannot collect systematic data, so that construction data does not contribute to the improvement of construction quality in the future. have.

The object of the present invention is to improve the construction quality in the subsequent process by measuring, recording and outputting the important factors in a series of process steps in the ground improvement method and geological survey in view of the conventional problems as described above. It is a ground improvement method that can contribute to the improvement of construction quality, the collection and management of cases in various situations occurring in actual construction, the accumulation of know-how and the improvement of construction in future And construction data control devices such as geological surveys.

Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

The present invention binds to both ends of the chain (2) wound on a pair of chain sprocket (1) driven by a hydraulic motor, slides along the boom (3) and has a built-in clamp for clamping the rod (4) In the boring machine (6) provided with), a rod holding clamp of the drum (5) and the spindle (5) wound around the drum rotated by a spiral spring on the upper end of the boom (3) and the drum; Depth measurement device (8) consisting of a drum rotation speed detection sensor capable of detecting the positive and reverse rotation associated with it is installed so that one end of the measuring machine (7) is bound to the spindle (5), the rotation speed of the rod clamp on the spindle (5) Rotation speed detection sensor 9 is attached to the load, the load cell 10 is attached to the end of the chain (2) attached to the lower portion of the spindle 5, the load amount for measuring the hydraulic pressure in the hydraulic line of the spindle (5) A detection sensor 11 is attached, and arithmetic processing and recording data detected by the sensor Characterized in that it comprises a construction data processing device 12 composed of a display unit and a printer unit for outputting.

The various elements measured by the present invention configured as described above are used as basic data of the ground structure, and are used as basic data for civil engineering work, and in the ground improvement method, as a factor for controlling various elements at the time of generation of modified liquor as data at the time of drilling. It is possible to accumulate know-how through scientific management of construction data.

The high pressure injection injection method of the ground improvement method is a method of improving the ground by ejecting a fraction of cement slurry at high pressure, crushing the ground, mixing the crushed part and the fraction to improve the cutting range, thereby creating a modified column, and improving the ground. Therefore, since the specifications of the modified stock are determined by the injection amount, injection pressure, time, and rotation speed of the rod as cement slurry, the injection pressure and the rotation speed of the rod are very important factors.

A hydraulic device is required for the operation of the construction equipment, the spindle load on the hydraulic line is detected by the load detection sensor 11, the rotational speed of the rod 4 is detected by the rotation speed detection sensor 9, and drilling The load per stratum required only for excavation for the drilling is detected by the load cell 10 installed in the chain 2 pulling down the spindle 5, and the drilling depth of the depth measuring device 8 measured by the rotation speed detection sensor. The measuring yarn 7 is detected by the number of revolutions of the wound drum.

Depth measurement is performed by a depth measuring device 8 composed of a drum, a measuring thread 7 and a rotation speed detection sensor, the forward rotation of the drum increases the depth, and the reverse rotation of the drum decreases the depth, The measurement of the rotation and the reverse rotation is configured to be measured only in the state in which the clamp for holding the rod 4 is pressed.

That is, when only the spindle 5 moves, the operation of the depth measuring device 8 is configured to be stopped. In order to drill to the planned depth, the rod 4 must be squeezed by the clamp of the spindle 5 to operate hydraulic pressure for rotation of the clamp and rotation of the chain 2. The drilling starts by the rotation of the rod 4 and is drilled by the transfer of the rod 4 by the chain 2. The rotational speed detection sensor of the depth measuring device 8 distinguishes and detects the forward and reverse rotation of the drum, which is necessary in the process of generating the refined column by spraying the fractionation body in the rod 4 after the drilling. When drilling is performed, the rotational speed of the drum is detected and converted into a distance, and one rod 4 is inserted into the ground, and when the spindle 5 is raised to press the other rod 4, the clamp is released. In this case, the rotation speed of the drum is not measured. After the other rod 4 is mounted and clamped with a clamp, excavation for drilling is started again. In this case, since the clamp is pressed, the rotation speed of the drum is detected. Then, when the spindle 5 is raised, the measuring thread 7 is wound on the drum again by the restoring force of the spiral spring.

The rotation speed of the drum detected by the above process is converted into a distance in the construction data processing apparatus 12, digitally displayed on the display unit, and a depth is output from the printer unit. When the drilling reaches the planned depth, the drilling is stopped, and the jetted jet is injected at high pressure at the end of the rod 4 to generate a modified column. When the rod 4 is drawn while generating the modified column, the drum of the depth measuring device 8 rotates in reverse. When the rod 4 is pulled out, the clamp is holding the rod 4 so that the drum rotates in reverse. The number is measured, and it is calculated and subtracted from the depth. Therefore, the depth of control increases with forward rotation of the drum, and the depth of depth decreases with reverse rotation of the drum.

In the drilling step, the rotation speed of the rod 4 is calculated by outputting the rotation speed of the clamp detected by the rotation speed detection sensor 9, and the load amount at the time of drilling is detected by the load cell 10. Since the spindle 5 is transported by the chain, the load at the time of drilling becomes a tensile load on the chain 2.

The rotational speed and load amount at the time of drilling indicate the weakness of the ground, and are used as basic data for the ground, and the ground improvement method determines the jetting pressure of the jetted body (injectant) and the rotational speed of the rod 4 at the time of generating the modified column. It becomes a factor.

This accurate measurement and recording of depth allows for accurate detection of planned depth and accurate generation heights for reformers.

The data at the time of drilling is used at the time of generation of improved column, the injection pressure of the fractionation body and the rotational speed of the rod 4 are controlled by the detection data. In other words, the larger the injection pressure, the larger the diameter, and the smaller the rotational speed of the rod 4, the larger the diameter. Therefore, the injection pressure and the rotation speed of the rod 4 are determined according to the determination of the ground hardness at the time of drilling.

All of the above detection elements are delivered to the construction data processing apparatus 12, arithmetic, stored and output. Factors output from the construction data processing apparatus 12 are the puncturing load and puncture time of the rod 4 during the puncture operation, the puncturing rotation speed and the puncturing depth of the rod 4, and at the tip of the rod 4 after the puncture is completed. It is the rotational speed of the rod 4 at the time of the construction work which produces | generates the refined column which draws out the rod 4, while spraying a high pressure jet body, and produces the refinement column, and the load amount of the spindle hydraulic line applied to boring machine equipment. The type and number of output parameters can be adjusted or adjusted, and the output format can also be changed. It can also be digitally digitized or output as an analog graph.

As such, the construction data of the various support panel improvement works can be scientifically managed to be used as basic data of the ground by improving the construction quality by the present invention, which measures the construction data, and manages the storage and output.

As described above, the present invention measures, records, and outputs important factors of excavation construction, so that the basic data of the ground can be scientifically recorded and managed, and in the ground improvement method, after generating the modified column from the measured data in the drilling excavation process, In order to improve the construction quality, it is effective to improve the construction quality by using it as a change factor of the controlled element, and it is possible to scientifically manage the case in various situations that occur in actual construction, so that the effect of know-how accumulation and the future There is an effect that can contribute to the improvement of construction.
