Description
Technical Field
The invention relates to the technical field of constructional engineering, in particular to a deep foundation pit monitoring system based on the Internet of things.
Background
The foundation pit engineering mainly comprises foundation pit supporting system design and construction and earthwork excavation, and is a system engineering with strong comprehensiveness. It requires close cooperation between geotechnical engineering and structural engineering technicians. The foundation pit supporting system is a temporary structure and is not needed after the construction of underground engineering is finished. The deep foundation pit is generally defined as: the bottom area is within 27 square meters, the long side of the bottom is less than three times of the short side, the excavation depth exceeds 5 meters (including 5 meters) or more than three layers (including three layers) of the basement, or the depth does not exceed 5 meters, but the geological conditions, the surrounding environment and underground pipelines are particularly complicated.
In the construction of a high building, a foundation pit is a foundation for ensuring the stability of the high building, the depth of the foundation pit is deeper and deeper as the building is higher, the monitoring technology of the deep foundation pit is particularly important in the construction process of the deep foundation pit, and various related monitoring parameters, such as ground surface settlement monitoring, soil body inclination monitoring, adjacent building settlement and inclination monitoring, support shaft force and stress monitoring, water level and water and soil pressure monitoring and the like, need to acquire the monitoring parameters so as to analyze data subsequently and investigate engineering hidden dangers, so that the safety, the accuracy and the timeliness of the monitoring data are very important. Because the pit wall of deep basal pit slumps easily, it is bigger for the collapse risk of ordinary foundation pit, if can not carry out real-time control to deep basal pit, because the excavation of deep basal pit soil body, the external load effect, under factors such as rainwater among the natural environment corrodes, can lead to the foundation pit to take place to warp, the foundation pit warp generally including pit wall warp, the soil layer removes around the foundation pit, aspects such as basement elasticity uplift and plastic uplift, cause the deep basal pit boundary soil body to take place the collapse that the phenomenon arouses deep basal pit that slides even, in case take place deep basal pit to collapse, to constructor, the progress of construction equipment and construction all can cause serious influence.
At present, a traditional mode of maintaining a deep foundation pit is that reinforcing steel bars are adopted to reinforce and form an enclosure structure, a supporting structure formed by a steel supporting system is installed in the enclosure structure, the supporting structure formed by the steel supporting system is an adjustable assembly type supporting system, the effect can be exerted without maintenance, prestress can be applied after installation, the deep foundation pit maintenance device is suitable for foundation pits of different shapes, and foundation pit displacement cannot be caused due to node looseness. The steel support system is basically consistent with the preset after-axle force, pre-stress and pre-stress after erection and locking, and is not adjusted subsequently, so that once the deep foundation pit is deformed, the steel support system cannot generate stable supporting stress for the deep foundation pit, further the foundation pit support structure is deformed, the protection structure of the deep foundation pit cannot normally play a role, the risk of collapse exists, and the progress of constructors, construction equipment and construction can be seriously influenced. If the supporting stress of the deep foundation pit needs to be changed, corresponding adjustment needs to be carried out according to collected monitoring data of the deep foundation pit, although the situation that constructors are assisted to adjust a steel supporting system through the monitoring data of the deep foundation pit is already existed at present, the work is still completed manually due to the fault tolerance and the accuracy degree of the adjusting process of the steel supporting body, and the purpose that the steel supporting system is adjusted automatically instead of manually through the monitoring data of the deep foundation pit to change the supporting stress of the deep foundation pit cannot be achieved.
