[0001] The utility model relates to the technical field of MJS construction equipment, in particular to an automatic monitoring and control device for spraying of a matching MJS construction machine, in particular to a pressure detection, wireless communication, remote monitoring and control device. Background Art

[0002] The MJS method is also known as the all-round high-pressure jetting method. This method can solve the problems of slurry delivery and environmental impact in horizontal rotary jetting construction. It uses a unique porous pipe and front-end device to realize ground pressure monitoring and MJS slurry automatic control, and controls the ground pressure by adjusting the forced slurry discharge volume. The impact on the environment is greatly reduced, and the reduction of ground pressure also further guarantees the pile diameter.

[0003] The current MJS method has strict requirements on the ground pressure and the amount of grouting during the construction process. Since the MJS equipment is lifted step by step from bottom to top and the hydraulic motor rotates and swings to spray, each depth corresponds to a pressure safety range. If the construction pressure is too high, it may cause the surface deformation. If the construction pressure is too low, the pile hole quality will be poor. The current MJS method equipment is judged by the experience of the construction personnel and does not have an automated detection function. The amount of grouting of the MJS equipment has high requirements on the quality of the pile. If the amount of grouting is too low during the construction process, the pile hole quality will be unqualified, and if the amount of grouting is too high, it will cause waste. At this time, the front-end operator needs to maintain communication with the back-end grouting personnel to ensure the accuracy of the grouting amount. Summary of the invention

Among them, the front-end monitoring and control device 1 is installed on the MJS method equipment 2, and is connected to the pressure sensor 5 installed on the drill bit through a cable. The back-end control device 3 is connected to the mud pump station 4 and the electromagnetic flowmeter 5 through a cable. The mud pump station 4 is connected to the drill rod of the MJS method equipment 2 through a slurry delivery pipeline. When working, the front-end monitoring and control device 1 reads the working pressure in the ground through the connected pressure sensor 5, and reads the depth of the MJS method equipment 2 at the same time, and performs pressure comparison through the system control program. If the pressure exceeds the normal range, it is transmitted to the mud pump station 4 through wireless transmission to alarm the front and back at the same time. The back-end mud pump station 4 is connected to the electromagnetic flowmeter 5 through a wired connection, and transmits the slurry delivery flow to the front-end monitoring and control device 1, and controls the MJS method equipment 2 through the control program to perform stepping motion control.

Then the pressure data is compared with the upper and lower limit range of the pressure. If the pressure data exceeds the range, the controller 2 drives the alarm indicator light 17 connected to the intermediate relay 11 to alarm, reminding the operator to adjust the pressure so that the pressure inside the MJS method equipment is kept in the normal range. At the same time, the controller 2 displays and records the current pressure data in the memory connected to the touch screen 12, and the workers can query and export the data alarm at any time.
