Description

Technical Field

[0001] The utility model relates to the technical field of construction foundation pits, in particular to an intelligent detection system for foundation pits. Background Art

[0002] Nowadays, foundation pits are excavated soil pits and construction spaces for building foundation construction. With the large-scale construction of subways, large-span bridges, and high-rise and underground buildings, foundation pits, especially deep foundation pits, have become an important source of safety risks in construction, and the detection of foundation pit deformation has also become an important part of construction safety management. During the construction process, if the deformation of the foundation pit cannot be detected in time, it will bring great safety hazards. The safety and stability of the foundation pit is the prerequisite for ensuring the safety of engineering construction. With the continuous expansion of the scale of foundation pit construction, the detection and early warning of foundation pit safety are becoming more and more important.

[0003] The foundation pit deformation detection is to use precision instruments and equipment to conduct comprehensive monitoring of the displacement, inclination, settlement, stress, cracking, base uplift, soil pore water pressure and dynamic changes of groundwater level of supporting structures and surrounding environment, such as rock mass, buildings, roads, underground facilities, etc. during the excavation process of the foundation pit. From the analysis of a large number of foundation pit engineering accidents, we can draw the following conclusion: Any foundation pit engineering accident is directly related to poor, inaccurate and untimely monitoring without exception. Foundation pit engineering monitoring is an important means to verify the correctness of the design plan, and it is also a necessary measure to timely guide correct construction and avoid accidents.

[0004] In the existing foundation pit monitoring, manual monitoring equipment is required to be used for regular monitoring of the foundation pit, and manual data comparison is required after the monitoring, which results in uncertainty in manual monitoring. It is impossible to give an alarm in time when the foundation pit is deformed, and the deformation of the foundation pit cannot be monitored, leaving hidden dangers for subsequent engineering construction. In addition, when manual monitoring is performed, the detection frequency is high, which increases the workload of the staff and is prone to foundation pit detection errors.

[0005] Therefore, it is necessary to provide an intelligent foundation pit detection system to solve the above technical problems. Utility Model Content

A foundation pit intelligent detection system comprises: a mounting plate 1;

[0030] A housing 2, wherein the housing 2 is fixedly mounted on the top of the mounting plate 1, a laser transmitter 29 is fixedly mounted on the bottom of the housing 2, and an ultrasonic radar component 20 is also fixedly mounted on the bottom of the housing 2;

[0031] A receiving component 4, which is arranged at the bottom of the housing 2, and includes a placement plate 41, two support plates 42, a laser receiver 43, two telescopic rods 44 and a conical block 45. The two support plates 42 are respectively fixedly mounted at the two ends of the top of the placement plate 41, and the middle of the two support plates 42 is rotatably connected with the laser receiver 43, and the bottom of the laser receiver 43 is fixedly mounted with a conical block 45;

[0032] The control component 28 is arranged at the bottom of the inner side of the shell 2. The control component 28 is provided with a storage module, an analysis module and a remote transceiver module. The connection ends of the control component 28 are electrically connected to the laser emitter 29, the two telescopic rods 44, the laser emitter 29 and the ultrasonic radar component 20 respectively. The connection ends of the control component 28 are also connected to the alarm component 3, the drive member 21 and the user terminal 5 respectively.

[0033] The two telescopic rods 44 are respectively fixedly installed inside the two supporting plates 42 , and one end of the two telescopic rods 44 is respectively disposed on two sides of the laser receiver 43 .

[0034] The alarm component 3 is fixedly mounted on the top of the housing 2 .

[0035] The driving member 21 is fixedly installed on the top of the inner side of the shell 2, and an active conical wheel 22 is fixedly installed on the output end of the driving member 21. A driven conical wheel 23 is meshed with the bottom of the active conical wheel 22. A rotating shaft 24 is fixedly installed inside the driven conical wheel 23. Winding wheels 25 are fixedly installed on both ends of the outer side of the rotating shaft 24. A pull rope 26 is wound around the outer side of the winding wheel 25, and one end of the two pull ropes 26 is fixedly installed on the two ends of the top of the placement plate 41 respectively.

[0036] Two ends of the rotating shaft 24 are rotatably connected to two sides of the inner side surface of the housing 2 respectively.

[0037] Guide tubes 27 are fixedly mounted on both ends of the bottom of the inner side of the housing 2 , and the guide tubes 27 are sleeved on the outer side of the pull rope 26 .

[0038] The user terminal 5 may be a tablet computer or a mobile phone. Through the cooperation between the user terminal 5 and the control component 28, when in use, the user can remotely control the laser emitter 29, the driving member 21 and the telescopic rod 44, and can also observe and monitor data on the user terminal 5 in real time;

[0039] The storage module, analysis module and remote transceiver module included in the control component 28 store the graphics formed by the ultrasonic radar component 20 in the storage module when they are used. When they are used later, the analysis module compares the real-time formed image with the data stored in the storage module. When the images are different, the remote transceiver module transmits a remote signal to remind the user terminal 5, and the alarm component 3 can also automatically alarm at the same time, thereby increasing the intelligence of the detection equipment;

[0040] When the laser receiver 43 does not receive the laser emitted by the laser transmitter 29, the alarm component 3 will promptly give an alarm, and the remote transceiver module will also send a signal to the user terminal 5 to remind the user;

[0041] The control component 28 and the receiving component 4 can be connected by wire, and the transmission line can be wrapped around the outer side of one of the pull ropes 26, which is also convenient for the user to store the transmission line.

[0042] The working principle of the foundation pit intelligent detection system provided by the utility model is as follows:

[0043] When in use, the user first places the mounting plate 1 at the edge of the foundation pit opening, and then sends a signal to the control component 28 through the user terminal 5, so that the control component 28 controls the driving member 21, so that the driving motor 21 rotates to drive the active conical wheel 22 and the driven conical wheel 23 to rotate, and then the driven conical wheel 23 drives the winding wheel 25 to rotate through the rotating shaft 24, and the pull rope 26 wound on the winding wheel 25 is slowly released. At this time, the bottom of the pull rope 26 drives the receiving component 4 to move toward the bottom of the foundation pit until the bottom of the receiving component 4 contacts the bottom of the foundation pit, and the user releases a certain length of the pull rope 26 again;

[0044] At this time, since a conical block 45 is installed at the bottom of the laser receiver 43 to act as a counterweight, the laser receiver 43 can be rotated between the two support plates 42, and the laser receiver 43 is rotated to a horizontal plane to maintain a horizontal state. At this time, the user controls the telescopic rod 44 to extend, so that one end of the telescopic rod 44 is against the two sides of the laser receiver 43 to limit the laser receiver 43;

[0045] Then the user uses the user terminal 5 again, and the user terminal 5 controls the laser emitter 29 through the control component 28 to start emitting a laser beam downward, and then the user moves the mounting plate 1, and the mounting plate 1 drives the laser emitter 29 to move through the housing 2, until the laser emitted by the laser emitter 29 is received by the laser receiver 43;

[0046] Then the user starts the ultrasonic radar component 20 to make the ultrasonic radar component 20 emit ultrasonic waves to the inside of the foundation pit and receive them, thereby constructing the foundation pit into a three-dimensional image and transmitting them to the inside of the control component 28 for storage. At the same time, the dimensions of the inside of the foundation pit are measured and stored. After that, the user fixes the mounting plate 1 at the entrance of the foundation pit, and makes the ultrasonic radar component 20 and the laser transmitter 29 emit laser and ultrasonic waves in real time. When the foundation pit is deformed and the laser receiver 43 cannot receive the laser emitted by the laser transmitter 29 or the three-dimensional image of the foundation pit measured in real time is deformed from the three-dimensional image stored in the control component 28, an alarm signal will be sent to the user terminal 5 and the alarm component 3 will also emit lights and sounds to remind surrounding personnel, thereby increasing the intelligence of the equipment, facilitating user use, and improving construction safety.

[0047] Compared with the related art, the intelligent foundation pit detection system provided by the utility model has the following beneficial effects:

[0048] Through the coordination of the control component 28, the laser transmitter 29, the ultrasonic radar component 20, the alarm component 3, the laser receiver 43 and other structures, when in use, the ultrasonic radar component 20 can image the interior of the foundation pit in real time, and automatically compare it with the image generated when the equipment is installed, and the laser receiver 43 can receive the laser beam emitted by the laser transmitter 29. When deformation occurs in the foundation pit, the control component 28 can immediately sound an alarm to remind the staff. In this way, the staff does not need to perform manual inspection, which reduces the workload of the staff and increases the intelligence and automation of the equipment.

[0051] Specifically, the difference of the foundation pit intelligent detection system provided by the second embodiment of the present application is that, in the foundation pit intelligent detection system, a plurality of ground nails 6 are fixedly installed on the bottom of the placement plate 41.

[0052] The placement plate 41 has a certain weight, which not only increases the stability of the placement plate 41 when it is placed downward by the pull rope 26, but also makes it convenient to insert the ground nails 6 into the ground through gravity.

[0053] The working principle of the foundation pit intelligent detection system provided by the utility model is as follows:

[0054] When the bottom of the placement plate 41 contacts the ground, the ground nail 6 contacts the ground, and the bottom of the ground nail 6 is inserted into the ground, thereby limiting the placement plate 41 .

[0055] Compared with the related art, the intelligent foundation pit detection system provided by the utility model has the following beneficial effects:

[0056] By installing the ground nail 6 at the bottom of the placement plate 41, the bottom of the ground nail 6 can be inserted into the ground when in use, thereby limiting the placement plate 41 and increasing the stability of the placement of the placement plate 41.
