Description

Technical Field

[0001] The present invention relates to the field of foundation pit support induction technology, and in particular to a multi-angle integrated support vibration induction device and a multi-angle and multi-sided vibration induction method and system based on the device. Background Art

[0002] Foundation pit refers to the space below the ground excavated for the construction of building foundations and basements. During construction, the foundation pit needs to be supported. The commonly used support structures now only have a supporting function, and do not have the function of supporting and vibration sensing detection, which are separate functions.

[0003] The corners between some top facades and side facades are often the most easily overlooked parts of the foundation pit and are also the places with greater hidden dangers, which can easily cause slippage or unstable deformation during construction. The existing support auxiliary devices are generally fixed structures, and the support angles cannot be adjusted at will, especially for the corners of the foundation pit that are not right angles or the wall surfaces are not flat, but have inclined angles or curved edges, that is, forming two angles and three edges. The existing support auxiliary devices cannot match the support well, nor can they adjust the matching support detection, resulting in inaccurate detection. Therefore, the applicant previously submitted an application, publication number CN118007658A, for a support auxiliary device and a corner and bilateral monitoring method and system based on the device, which achieved certain monitoring, but could not achieve more accurate vibration monitoring, and lacked multi-faceted comparative data for construction condition judgment. The vibration sensing data at the corners is the most critical for construction, and the original operability and practicality are poor. If the application data needs to be coordinated with other intelligent equipment, the processing is even more lacking. Therefore, based on this technology, a further improvement is made to provide a multi-angle integrated support vibration sensing device and a multi-angle and multilateral sensing method and system based on the device. Summary of the invention

[0004] In order to solve the comprehensiveness of the above-mentioned vibration data, the present invention provides a multi-angle integrated support vibration sensing device, including a base plate, a vertical plate, and a hydraulic push rod.

[0007] Preferably, the adjusting rod is provided with a positioning hole in the vertical direction, and the number of the positioning holes is several. A threaded hole is provided at the top of the base plate on one side of the reinforcing seat, the threaded hole is connected to the through hole, a screw is threadedly connected to the inner wall of the threaded hole, the screw thread passes through the threaded hole and extends to the inside of the positioning hole, the number of the threaded hole and the screw are both two, and the outer diameter of the screw is the same as the inner diameter of the positioning hole. The base plate is movably connected to the vertical plate, and the two ends of the hydraulic push rod are movably connected to the base plate and the vertical plate respectively.

[0008] Preferably, a multi-angle and multi-sided support vibration sensing method based on the multi-angle integrated support vibration sensing device is:

[0009] Includes two corner and three side support vibration sensing:

[0010] 21) The device is installed at the foundation pit construction site and at the corner edge. The vertical plate of the device is used to assist in supporting the corner edge and is supported by a hydraulic push rod;

[0011] 22) The rotating disk drives the rotating rod to rotate, and then the rotating rod drives the second bevel gear to rotate, and then the second bevel gear meshes to drive the first bevel gear to rotate, and then the first bevel gear drives the threaded rod to rotate, and then the thread of the threaded rod drives the lifting rod to move up and down, so as to operate and control the height of the adjustment baffle, so as to facilitate the auxiliary support of the foundation pit on one side of the surface of different depths, and when the wall surface is non-planar or long, the adjustment baffle is extended, the threaded rod is extended, and separated from the contact sensing switch at the top of the lifting rod, and the contact sensing switch humidity sensor 2, pressure sensor 2, vibration sensor 2 are turned on, and after the adjustment baffle is adjusted to the corresponding height, the angle of the adjustment baffle is adjusted by rotating through the rotating shaft 2, and the adjustment baffle and the protective plate are rotated with the hinge as the axis to adapt to the non-planar wall for detection;

[0012] The adjustment baffle and the connected protective plate are connected to the hinge axis for rotation, and the two axes rotate simultaneously, so that the angle deformation between the adjustment baffle and the vertical plate can be completely fitted with the curved wall surface. After fitting, another pin can be inserted into the second rotating shaft for fixing to achieve stability;

[0013] By loosening the screw rod, the screw rod is pulled out from the positioning hole, so that the adjusting rod can be dragged from the through hole to adjust the position of the reinforcing seat, and by tightening the screw rod again, the screw rod is inserted into the positioning hole to fix the adjusting rod. In this way, the support stability of the substrate can be enhanced through the support of the reinforcing seat, and the pressing support can be adjusted again through the hydraulic push rod;

[0014] 23) connecting the integrated controller and the temperature, vibration sensor 1, humidity sensor 1, pressure sensor 1, humidity sensor 2, pressure sensor 2, and vibration sensor 2 for data collection, and connecting them to the communication network, so that the vertical plate, the adjustment baffle plate, and the base plate form both a support surface and a sensing surface of the electronic device, realizing support and sensing monitoring of two corners and three sides;

[0016] 25) Process and analyze the collected data to generate construction reports and early warning information;

[0017] 26) Transmit report and warning information to the supervision information management system for comprehensive monitoring, surveillance and early warning.

[0018] If the vibration sensor detects abnormal vibration, compare the vibration data of pressure sensor 2 and vibration sensor to determine the source of the vibration direction, check the environment around the foundation pit, eliminate external interference factors, and compare the data of humidity sensor 1 and humidity sensor 2 to check whether the wall itself has cracks or looseness, and then check whether there are any abnormalities in the supporting structure. Continue to monitor the vibration. If the vibration persists or intensifies, emergency measures must be taken to ensure construction safety;

[0019] When the humidity sensor detects a sudden increase in the value, it means that there is groundwater infiltration or rainwater accumulation in the wall. At this time, it is necessary to check whether the drainage system around the foundation pit is normal and whether there is water infiltration into the wall. At the same time, pay close attention to the change trend of humidity to determine whether further waterproofing measures are needed;

[0020] The safety thresholds of pressure sensor 1 and pressure sensor 2 are set. When the data of the pressure sensors exceeds the set safety thresholds, or the difference between the two pressures exceeds the safety difference value, the risk of wall collapse is determined in combination with the vibration data. The relevant construction operations are immediately stopped, the personnel on site are evacuated, and the wall is inspected and evaluated in detail. The stability of the supporting structure is checked to see if there is any looseness or abnormal deformation. According to the evaluation results, corresponding reinforcement measures are taken, such as increasing the support and adjusting the pressure of the hydraulic push rod (3).

[0021] The above-mentioned multi-angle and multi-sided support vibration sensing method simultaneously forms a multi-angle and multi-sided vibration monitoring system.

[0022] The present invention has the following advantages:

[0023] A multi-angle integrated support vibration sensing device is realized, and an integrated double-angle and three-side arbitrarily adjustable support auxiliary device is realized. The operation is simple and practical. A multi-surface area deformable sensing support device is realized by a support body, which integrates support and sensing functions. The vibration sensing data at the corners is accurate and comparative, and more sensing data can be provided for intelligent sensing equipment. The sensing of two corners and three sides can be effectively sensed regardless of simple corner conditions or complex working conditions. The sensors are monitored and data collected in real time through the central platform, and processed and analyzed in time. Problems can be quickly discovered and accurate construction reports and early warning information can be generated to realize a hierarchical monitoring strategy. Different sensor combinations and monitoring processes can be adopted according to different working conditions and needs, which not only ensures the comprehensiveness of monitoring, but also avoids unnecessary waste of resources, realizes information management, and transmits monitoring data to the supervision information management system, realizes comprehensive monitoring, supervision and early warning, facilitates the management and decision-making of the construction process by all relevant parties, and makes it easier to realize the application of intelligent equipment.
