Description

Technical Field

[0001] The utility model relates to the technical field of support engineering monitoring, in particular to a hydrogeological support engineering monitoring device. Background Art

[0002] Hydrogeology refers to the various changes and movements of groundwater in nature. Hydrogeology is the science of studying groundwater. It mainly studies the distribution and formation of groundwater, the physical properties and chemical composition of groundwater, groundwater resources and their rational utilization, the adverse effects of groundwater on engineering construction and mining and their prevention and control, etc. Before excavating the foundation pit, it is necessary to analyze and evaluate the groundwater and geology of the excavation location to ensure the safety of subsequent excavation. When the current location meets the excavation requirements, the foundation pit excavation operation can be carried out. During the foundation pit excavation, the foundation pit support will be fixed. The foundation pit support is a support, reinforcement and protection measure for the side walls of the foundation pit and the surrounding environment to ensure the safety of the underground structure construction and the surrounding environment of the foundation pit.

[0003] For example, a Chinese patent (CN218116474U) discloses a hydrogeological support engineering monitoring device, including a mounting base plate, which is integrally mounted at the bottom of a foundation pit. Before using the device, the mounting base plate is first installed in the foundation pit, and then the length of the second telescopic rod is adjusted according to the width of the foundation pit, and the positioning plate is adjusted to be in contact with the supporting piles. During use, the force applied to the positioning plate can be monitored by a pressure sensor. When tilting occurs, the supporting piles will squeeze the positioning plate, causing the force applied to the pressure sensor to increase. When the force exceeds the set range, an audible and visual alarm can sound an alarm to remind the staff to make adjustments. When settlement occurs, the color surface will move downward. When it moves to the lower end of one side of the color sensor, the color sensor cannot receive a signal, and the audible and visual alarm can be controlled to sound an alarm, so that automatic monitoring of the support part can be achieved, thereby improving the overall safety of use.

[0004] The above scheme also has the following technical defects: the above scheme is not convenient for adjusting the distance between the two positioning plates according to the width of the foundation pit. Since there is a certain distance between the positioning plates and the bottom wall of the foundation pit, the staff often need to hold the mounting frame and the second telescopic rod for a long time when manually adjusting the distance between the positioning plates, which undoubtedly increases the difficulty of the staff's work. Based on this, a hydrogeological support engineering monitoring equipment is proposed. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a hydrogeological support engineering monitoring device, which has the advantages of convenient automatic support of support piles and solves the problem of manual adjustment of the position of the positioning plate.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hydrogeological support engineering monitoring device, comprising a foundation pit, two support piles abutting against the left and right sides of the foundation pit, a bottom plate placed at the bottom of the foundation pit, four conical positioning rods fixed to the bottom end of the bottom plate, a telescopic plate fixed to the top of the bottom plate, a supporting mechanism provided on the telescopic plate, a fixing mechanism provided on the telescopic plate, two pressure sensors provided on the supporting mechanism, and a controller body and an alarm fixed to the top of the bottom plate;

[0007] The supporting mechanism includes two mounting plates abutting against the left and right sides of the telescopic plate, a motor is fixed to one side of the mounting plate, a first screw rod is fixed to the output shaft of the motor, the supporting mechanism also includes a second screw rod rotatably connected to one side of the mounting plate, a transmission assembly is provided on the outer surfaces of the first screw rod and the second screw rod, a movable plate is threadedly connected to the outer surfaces of the first screw rod and the second screw rod, a positioning plate is fixed to one end of the movable plate, and two rubber pads are fixed to the side of the positioning plate away from the movable plate.

[0008] Furthermore, the fixing mechanism includes two pairs of mounting grooves opened on the telescopic plate, a moving rod is slidably connected inside the mounting groove, a baffle is fixed to one end of the moving rod, a rectangular plate is fixed to the end of the moving rod away from the baffle, a limiting rod is fixed to the side of the rectangular plate close to the moving rod, and a spring is sleeved on the outer surface of the moving rod.

[0009] Furthermore, one side of the rubber pad is in contact with one side of the supporting pile, and the side of the positioning plate away from the moving plate is fixed to the pressure sensor.

[0010] Furthermore, the transmission assembly includes a driving wheel fixed on the outer surface of the first screw rod, a driven wheel fixed on the outer surface of the second screw rod, and a transmission belt transmission-connected to the outer surfaces of the driving wheel and the driven wheel.

[0011] Furthermore, the conical positioning rod is inserted into the foundation pit, and the pressure sensor fits the supporting pile.

[0012] Furthermore, one end of the spring abuts against one side of the mounting groove, and the other end of the spring abuts against the baffle.

[0013] Furthermore, two limiting holes are provided inside the mounting plate, and the limiting rod can abut against the limiting holes.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The hydrogeological support engineering monitoring equipment can automatically support the support piles by providing a supporting mechanism on the telescopic plate, without the need to manually adjust the position of the positioning plate, thereby eliminating the need for workers to lift the supporting mechanism for a long time, thereby reducing the work intensity of the workers. By providing a fixing mechanism on the telescopic plate, the supporting mechanism can be easily installed and disassembled, thereby facilitating the separate transportation of components such as the base and the supporting mechanism.
