Description

Technical Field

[0001] The present invention relates to the technical field of cement mixing pile production safety and quality safety monitoring, and in particular to a cement mixing pile construction omnidirectional monitoring system and monitoring method. Background Art

[0002] Cement mixing piles are often used to treat soft soil foundations and strengthen their bearing capacity. However, as a common and long-standing construction method, they lack real-time monitoring of safety, quality control, and progress. This often leads to issues such as shoddy workmanship, tilted piles, inaccurate spacing, hazardous production processes, and failure to maintain bearing capacity. Common monitoring methods include manual spot checks of the cement slurry's water-cement ratio, shotcrete pressure at the slurry tank, and pile driving time; regular measurements of the settlement and tilt of surrounding buildings; manual inspections of on-site safety issues and reminders; and manual review of pile driving points and progress records. Overall, these methods suffer from high labor costs, inability to fully monitor the entire process, significant data deviations, and limited guidance.

[0003] A Chinese utility model patent (publication number CN214832949U) was published in 2021 for an intelligent monitoring system for cement mixing piles. This system includes an operating platform and a positioning antenna integrated into the cement mixing piles. It uses a water-cement ratio monitoring component, a positioning antenna, a speed sensor, and a pressure sensor to transmit real-time monitored data to the operating platform and to the cloud via 5G signals, allowing staff to monitor the working status in real time. While this device monitors the construction process of cement mixing piles, it cannot monitor surrounding settlement. The acquired positioning data and construction data are not accurate enough, preventing on-site construction personnel from receiving timely alerts and viewing the corresponding data in real time to make adjustments.

[0040] The second shock-absorbing box 2072 is a rectangular parallelepiped, and a certain gap is left between it and the monitoring box 211, which serves as the freedom space of the second spring shock-absorbing system 207; the depth and inclination monitoring device 2 is installed on the outside of the drill rod protection cage of the cement mixing pile, close to the object to be safely monitored, which can better ensure the safety of monitoring the safe distance between the cement mixing pile and the object to be monitored.

[0041] Further, combined Figures 6-11 As shown, the pile body quality monitoring device includes an annular shell 309, which is separated into multiple partitions, one of which is provided with a second UWB tag 301, at least one partition is provided with a pressure sensor 304, and the remaining partitions are provided with a water-cement ratio sensor 302; a casing 308 is sleeved in the inner ring of the annular shell 309, and the casing 308 is connected and communicated with the annular shell 309 through a plurality of connecting pipes, the connecting pipes including a first connecting pipe 303 connected to the partition where the water-cement ratio sensor 302 is located, and a second connecting pipe 305 connected to the partition where the pressure sensor 304 is located; the two ends of the casing 308 respectively extend from the inner ring of the annular shell 309 and are provided with threads, and the casing 308 is connected to a mud pipe and a drill pipe thruster arranged on the pile head of the cement mixing pile.

[0042] By partitioning the interior of the annular shell 309, a plurality of independent small spaces can be separated, and these small spaces can be used to install the pressure sensor 304, the water-cement ratio sensor 302 and the second UWB tag 301, so that these components can be integrated into the same device and can also be relatively independent and not interfere with each other; the arrangement of the casing and the connecting pipe is convenient for connecting and supporting the annular shell and installing the entire pile body quality monitoring device on the pile head, and can also form a structure connected with certain partitions so that the transported cement slurry can enter and exit certain partitions, so as to monitor the pressure, water-cement ratio and other data of the cement slurry.

[0043] The pile body quality monitoring device 3 is installed on the top of the drill rod of the cement mixing pile. The casing 308 is connected to the mud pipe and the drill rod thruster up and down. During construction, part of the mud in the mud pipe will flow into the pressure sensor and the water-cement ratio sensor 302 through the connecting pipe to complete the measurement of the corresponding parameters. The grouting pressure at the pile head and the water-cement ratio of the slurry can be accurately obtained. Combined with the piling depth, it avoids the situation where the cement consumption is reduced due to the loss of pressure during the transmission process, avoids the potential problem of cutting corners when the mud water-cement ratio at the mud pool is qualified but the mud water-cement ratio at the piling location is unqualified, and avoids the situation where the device follows the pile head into the ground and causes damage or pollution to the device.

[0044] Furthermore, an upper shell and a lower shell are respectively provided above and below the annular shell 309, a second inclination sensor 306 is provided in the upper shell, and a third battery 307 is provided in the lower shell.

[0045] Furthermore, the partition includes four fan-shaped partitions, including a pair of large fan-shaped partitions and a pair of small fan-shaped partitions. The pressure sensor 304, the first water-to-cement ratio sensor 302, the second UWB tag 301, and the second water-to-cement ratio sensor 302 are arranged in a counterclockwise direction. The pair of water-to-cement ratio sensors 302 are symmetrically arranged in a pair of large fan-shaped partitions, which is conducive to overall balance and accurate data measurement. Multiple water-to-cement ratio sensors 302 are used alternately, so that the water-to-cement ratio sensors 302 have sufficient time to complete water-to-cement ratio monitoring. The second inclination sensor 306 is an annular structure, and the third battery 307 is an annular rechargeable battery. This annular structure can arrange the two at the top and bottom, rationally utilizing the space above and below the annular shell, making the entire device simpler and more compact.
