知警報を発生してこれをオペレータに知らせる。Here, the amount of change in the formation hardness is obtained by processing a moving average of changes in the mandrel drive oil pressure sampled at regular intervals, and this value is determined by the formation hardness set in the setting device 67 in the arithmetic processor 61. It is compared with the change amount threshold. At this time, the arithmetic processor 61 also compares the mandrel depth with a depth threshold set in the setting device 67, and after the mandrel depth exceeds the depth threshold, the amount of change in the formation hardness is determined to be the threshold for the amount of change in the formation hardness. When the mandrel 23 has reached the bottom layer g4, a bottom layer detection signal is sent to the remote measurement command device 15. Upon receiving this signal, the remote measurement command device 15 generates a bottom layer arrival detection alarm and notifies the operator of this.

底層到達検知の正・否を判定する。When the bottom layer arrival detection alarm occurs, the operator determines whether the bottom layer arrival detection is correct or not, taking into consideration the situation of the existing paper piles that have been driven adjacent to the pile.

If not, a reset command is sent to the calculation/processing/recording device 13, and the mandrel 23 continues to penetrate.

し１表示させる。In order to measure and process the upper end depth d2 of the bottoming layer g4, the mandrel depth sampled in the same manner at the same time as the mandrel drive oil pressure is stored in the storage unit in the arithmetic processor 61 every time the moving average processing of the mandrel drive oil pressure is performed. It has been rewritten and temporarily stored. The mandrel depth value stored at the latest time that contributed to the moving average processing in this storage section indicates the maximum mandrel depth at that time, and the mandrel depth value stored at the oldest time indicates the calculation process at that time. This is the depth data of the starting point of the change in stratum hardness. When the bottom layer detection signal is sent out, each depth data is held, and the difference is transferred to the remote measurement command unit 15 as the bottom layer penetration amount d of the mandrel 23 and displayed as 1.

出された場合には前記深度データは解除される。As a result, the operator knows with certainty that the paper 31 has penetrated the bottom layer g4, and thereafter, as described above, the remote measurement command unit 15 sends out a bottom contact confirmation command. These are processed as the depth d1 and bottom layer top depth d2 and stored in the storage unit. Further, when a reset command is sent instead of a bottom-hitting confirmation command, the depth data is canceled.

この場合、ペーパー杭番は更新されない。The paper 31 remains in the ground G, but may rise together with the mandrel 23. The calculation/processing/recording device 13 monitors this co-increase, and when the value exceeds the paper co-increase amount threshold set in the setting device 67, it sends a signal to the remote measurement command device 15 to generate an alarm. . The operator quickly takes measures such as re-penetration in accordance with the paper upstream detection alarm issued by the remote measurement command device 15. If re-penetration is not appropriate, the operator first pulls out the mandrel 23 to the ground and then sends it to the remote measurement command device 15. Send a reprinting command and reprint paper 31 again.
In this case, the paper pile number is not updated.

If the co-rise does not exceed the paper co-rise amount threshold, the operator sends a pouring completion command from the remote measurement command device 15 to the calculation/processing/recording device 13 to complete the pouring. As a result, the arithmetic processor 61 of the arithmetic/processing/recording device 13 reads the mandrel maximum depth d1 and the top depth of the bottom layer d2 that were stored in the storage unit at the time of bottoming, and calculates the paper casting depth d4 at the time of completion of casting. The difference from the bottom layer upper end depth d2 is defined as the bottom layer paper penetration amount d, and the daily total and cumulative total of the paper placement amount are calculated, and the results of these placement data are edited into a format that is easy to manage. The results of these pouring data are sent to the printer 77.
The information is sent to the computer and printed out, and is also stored in a storage device 63 that can be taken out externally. The results of the pouring data stored in the storage device 163 are taken out of the storage device 63 and returned to another data processing device, where they are used to create a pouring summary table and a pouring floor plan. Thereafter, the paper pile number is updated and similar paper driving work is carried out one after another.

られる。(Effects of the Invention) The present invention is configured as described above, and in the paper drain installation method, the paper penetrates the soft layer to be improved and reliably reaches the hard sandy stratum such as the alluvial sand layer that becomes the drainage layer. The formation hardness change threshold and the depth threshold set in the setting device 67 are compared with the formation hardness change amount and the mandrel depth to determine whether the formation hardness change has penetrated after the mandrel depth exceeds the depth threshold. It is determined that the mandrel has reached the bottom layer only when the amount exceeds the stratum hardness change threshold, so even if there is a hard sandy soil layer in the soft layer, there will be a small number of polls. With this method, it is possible to confirm that all the paper has reached the bottom layer, and it is possible to completely prevent the failure or rework of pouring work due to the paper not reaching the bottom layer, making it possible to improve soft ground. The effect is that construction can be done quickly and economically.

パードレーン打設工事における施工監視・管理装置。(1) A construction monitoring and management device for paper drain installation work used in soft ground improvement work, which is equipped with a detection unit, a calculation/processing/recording device, and a remote measurement command device.
The detection section detects the mandrel movement amount, mandrel drive oil pressure, etc., and transfers it to the calculation/processing/recording device, and the calculation/processing/recording device processes the signal from the detector and records it. The remote measurement command device issues a measurement processing command to the calculation/processing/recording device, and compares it with appropriately set threshold values such as depth and layer hardness change, and creates a bottom layer detection signal based on the result. A construction monitoring and management device for paper drain installation work, characterized by sending out a bottom layer arrival detection alarm based on a bottom layer detection signal.
