Description

Technical Field

[0001] The utility model relates to the field of measurement probes, in particular to a rapid measurement probe for multi-terrain foundation pits. Background Art

[0002] Foundation pit measurement is an important task during the construction and use stages of building foundation pits. It involves regular or continuous inspections, measurements, monitoring, as well as data collection, analysis, and feedback activities on the safety conditions, change characteristics, and development trends of foundation pits and their surrounding environments. Foundation pit measurement mainly measures the stress and strain states of surrounding rocks and support structures at each construction stage through rapid measurement probes to judge their stability.

[0003] During the use of existing rapid measurement probes, they can usually only measure foundation pits with specific terrains. When facing foundation pit environments with large terrain differences, the rapid measurement probes cannot be stably fixed in the foundation pit environment, which easily leads to the measurement probes tilting and falling, and unable to accurately measure the interior of foundation pits with multiple terrains.

[0004] Therefore, aiming at the problem that the above-mentioned rapid measurement probes are prone to tilting and falling, and unable to accurately measure the interior of foundation pits with multiple terrains, a rapid measurement probe for multi-terrain foundation pits can be designed. By designing and installing a support structure that can adapt to different environmental terrains on the outside of the rapid measurement probe, the measurement probe can be stably fixed in multi-terrain foundation pits, thus facilitating the solution of the above problems. Summary of the Utility Model

[0005] In order to overcome the problem that existing rapid measurement probes can usually only measure foundation pits with specific terrains during use. When facing foundation pit environments with large terrain differences, the rapid measurement probes cannot be stably fixed in the foundation pit environment, which easily leads to the measurement probes tilting and falling, and unable to accurately measure the interior of foundation pits with multiple terrains.

[0006] The technical solution of the utility model is as follows: A rapid measurement probe for multi-terrain foundation pits includes a hexagonal fixing frame, a support assembly, and a probe body. Six groups of folding grooves are circumferentially formed on the six sides of the hexagonal fixing frame, and six groups of support assemblies for adapting to multi-terrain foundation pits are respectively arranged inside the six groups of folding grooves. A probe bin is formed at the center of the hexagonal fixing frame, and a probe body for measuring foundation pit information is arranged at the bottom of the probe bin. The probe body includes an upper probe and a lower probe. A fixing plate for adapting to flat foundation pits is arranged below the hexagonal fixing frame.

[0007] Preferably, compared with the current measurement probes on the market, which are prone to causing the rapid tilting and toppling of the measurement probe and unable to accurately measure the interior of foundation pits with various terrains, in this application, a hexagonal fixing frame, a support assembly and a probe body are combined, so that the probe body can be installed inside the probe bin to measure foundation pits with various terrains. At the same time, the six support assemblies in the folding grooves of the hexagonal fixing frame can extend out and firmly insert into the ground of foundation pits with various terrains, thereby stably fixing the probe body inside the foundation pit to measure the foundation pit, thus improving the applicability of the measurement probe to foundation pits with various terrains.

[0008] As a preference, on the upper sides of the two side walls of the six folding grooves, rotation holes are respectively provided, and claw grooves are respectively provided at the bottoms of the six folding grooves. A support rod is provided between the hexagonal fixing frame and the fixing plate. There are multiple groups of support rods, and the multiple groups of support rods are arranged in a surrounding manner between the hexagonal fixing frame and the fixing plate. The hexagonal fixing frame and the fixing plate are fixedly connected through the multiple groups of support rods. Through the combination of the fixing plate and the support rods, when facing a normal and relatively flat foundation pit, the fixing plate and the support rods can stably support the probe body without opening the support assembly.

[0009] As a preference, the support assembly includes two first-stage extension arms and two second-stage extension arms. There are two movable shafts between the two first-stage extension arms and the two second-stage extension arms. The first and last ends of the two first-stage extension arms and the two second-stage extension arms are movably connected through the two movable shafts. On the outer sides of the ends of the two first-stage extension arms far away from the second-stage extension arms, rotating shafts are connected, and the rotating shafts extend into the interior of the rotation holes. Through the combination of the two first-stage extension arms and the second-stage extension arms, when facing a foundation pit with various terrains, the staff can stretch and extend the two first-stage extension arms and the second-stage extension arms through the movable shafts, so as to adapt to the complex terrain inside the foundation pit.

[0010] As a preference, at the ends of the two second-stage extension arms far away from the first-stage extension arms, support plates are provided. There are movable connection sleeves between the two second-stage extension arms and the support plates. The two second-stage extension arms and the support plates are movably connected through the movable connection sleeves. Support claws are provided at the lower ends of the support plates. Through the combination of the support rods and the support claws, when supporting the probe body, the support plates can expand the support points with the ground of the foundation pit, thereby improving the stability of the support of the support assembly. At the same time, the support claws can be inserted into the soil layer of the foundation pit to further improve the firmness of the support of the support assembly. At the same time, the support plates and the support claws can be folded and stored in the folding grooves and the claw grooves.

[0011] Preferably, a telescopic groove is formed in the center of the lower end of the lower probe. A measuring probe is arranged inside the telescopic groove, and a stress sensor is arranged inside the measuring probe. Battery compartments are formed inside both the lower probe and the upper probe. A primary battery pack and a secondary battery pack are respectively arranged inside the battery compartments. The primary battery pack is electrically connected to the measuring probe. By combining the measuring probe with the stress sensor, when the measuring probe is fixed at the bottom of the foundation pit, the primary battery pack can drive the measuring probe to insert into the soil layer of the foundation pit from the telescopic groove, and at the same time, the measuring probe can sense the change of soil layer stress through the internal stress sensor.

[0012] Preferably, four arc-shaped connecting blocks are arranged around the upper edge of the lower end of the lower probe. Thread grooves are formed around the outer ends of the four arc-shaped connecting blocks. A thread sleeve is arranged on the inner wall of the lower end of the upper probe. The thread sleeve and the thread grooves are matched with each other. By combining the thread grooves with the thread sleeve, the upper probe and the lower probe can be screwed together through the matching of the thread grooves and the thread sleeve.

[0013] Preferably, a rotating base is arranged above the upper probe. A turntable is arranged between the rotating base and the upper probe. The rotating base and the upper probe are movably connected through the turntable. The rotating shaft is electrically connected to the secondary battery pack. A displacement sensor is arranged at the outer end of the rotating base, and a wireless module is arranged inside the rotating base. By combining the turntable with the rotating base, the secondary battery pack can drive the turntable to drive the rotating base to rotate, so that the rotating base drives the displacement sensor to rotate, thereby measuring the displacement, settlement and inclination of the foundation pit. After the displacement sensor measures, the wireless module can transmit the measurement data of the foundation pit to the data terminal.

By combining the fixing plate and the support rod, when facing a normal and relatively flat foundation pit, the fixing plate and the support rod can stably support the probe body without opening the support component. By combining two groups of primary extension arms and secondary extension arms, when facing a foundation pit with various terrains, the staff can stretch and extend the two groups of primary extension arms and secondary extension arms through the movable shaft, so as to adapt to the complex terrain inside the foundation pit.
