Description
Technical field
The present invention relates to a kind of system that is used for the detection technique field, particularly a kind of unmanned air pressure caisson working caisson slope trend predicting system.
Background technology
Unmanned air pressure caisson working is by building an airtight operating room, and feeds certain pressurized air with the balance underground flood peak in the operating room, makes operation under anhydrous environment, and Work machine is all operated by ground remote control.This kind construction method has that construction site peripheral ground sedimentation is little, little to surrounding environment influence, operating efficiency is high, safe and reliable, structural strength is big, particularly because it very suitablely closely connects construction, so have development prospect.
Unmanned air pressure caisson working mainly contains three kinds of methods a kind of when caisson sinking be the method for drowning oneself, and promptly caisson sinking relies on the caisson body to conduct oneself with dignity to overcome the drag of the soil at soil layer friction force around the caisson body and cutting curb place fully; Also have a kind of improved method of drowning oneself, or reduce the caisson body and the frictional resistance on stratum on every side by taking measures, perhaps by add water or other weights in caisson, the deadweight that increases caisson is to overcome frictional resistance.Another kind method is forced sinking method, promptly comes by force casing to be pressed into method in the ground by the earth anchor counterforce device.Caisson is in the process of sinking, the caisson outer peripheral face is inhomogeneous with the friction force of ground interlayer for a certain reason, sword underfooting necromancer body does that power there are differences and reason such as the excavation mode is improper, especially since the supvr during to caisson sinking the slope trend of caisson indeterminate, and can not determine to take which kind of effective measures to prevent caisson slope, thereby cause caisson very easily run-off the straight in the sinking process, thereby threaten construction safety, reduce work efficiency.
By literature search, Chinese patent (application number 87102338) has provided a kind of caisson sinking method, this method is by excavating the supporting open drain of a caisson same level shape that has and sink, in the open drain that the support input that can support caisson but be easy to subside has automatically been excavated, and then the caisson body built on the open drain.By removing the stilt in the open drain,,, can effectively prevent caisson slope like this during sinking so the frictional resistance of caisson body periphery is basic identical because the open drain is dug in advance.But this method will be excavated the open drain in advance and need givey support, and quantities strengthens, and material therefor increases, and cost increases.In addition, this kind method is not suitable for the occasion of building caisson in water yet.
As previously mentioned, the main cause of caisson sinking is owing to grasp not clear to caisson stressing conditions and caisson attitude situation, and the control measure of can not taking to sink targetedly prevent that the caisson body from tilting, so be necessary to study a kind of novel caisson slope trend predicting system, decision-making foundation is provided during for caisson sinking, taking correct sinking measure, thereby reach the purpose that prevents caisson slope, also can guarantee the safety when the caisson body sinks.
