Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a deep foundation pit displacement detection alarm device, including a supporting plate 2 tightly attached to the pit wall of the foundation pit 1 and a plurality of supporting piles 3 pressing the supporting plate 2 against the pit wall, during installation, the supporting plate 2 is erected to lean against the pit wall of the foundation pit 1, then the supporting piles 3 are installed outside the supporting plate 2, the supporting plate 2 is pressed against the pit wall through the supporting piles 3, so that once the foundation pit 1 is displaced and deformed, the supporting plate 2 and the supporting piles 3 are inclined certainly, thereby changing the pulling force applied to the pulling rope 4, the processor 11 sends a control instruction to the controller 10 according to the abnormal pulling force signal, and the controller 10 controls the alarm lamp 9 to flash to alarm;
the specific setting mode of the deep foundation pit displacement detection alarm device is as follows: a tight pull rope 4 is connected between the two support piles 3, a tension sensor 5 for measuring tension of the pull rope 4 is installed on the pull rope 4, the tension sensor 5 transmits measured tension signals to a processor 11, the processor 11 sends control instructions to a controller 10 according to the tension signals, and the controller 10 controls an alarm lamp 9 to light and flash to give an alarm.
As shown in fig. 1 and 2, in order to improve the accuracy of detecting the deformation of the foundation pit 1 of the present device, a pull rope 4 should be connected between two adjacent support piles 3, and the distance between two adjacent support piles 3 should not be too large, and the smaller the distance, the higher the detection accuracy.
As shown in fig. 1 to 3, in order to facilitate installation of the pulling rope 4, a mounting post 13 is detachably mounted on the support pile 3, and one end of the pulling rope 4 is wound around the mounting post 13.
The quantity of alarm lamp 9 equals with tension sensor 5's quantity, and alarm lamp 9, treater 11 and controller 10 are all installed on mounting panel 8, and mounting panel 8 can set up in foundation ditch 1 or near the position that is easily seen by the workman, also can set up in the control room and monitored by the special messenger.
In order to facilitate the monitoring personnel to timely judge the position of the displacement deformation of the foundation pit 1, the alarm lamps 9 are in one-to-one correspondence with the tension sensors 5, as shown in fig. 1, all the tension sensors 5 form a rectangle, and all the alarm lamps 9 also form a rectangle, so that the position of the support pile 3 inclined in the foundation pit 1 can be visually judged by observing the alarm lamps 9 flashing and lighting on the rectangle, namely the position of the displacement deformation of the foundation pit 1.
In order to improve the alarm efficiency and enable a worker or a monitoring person to know alarm information in time, a buzzer 12 electrically connected with a processor 11 can be additionally arranged on the mounting plate 8, when the processor 11 sends an alarm signal to the controller 10, the processor 11 simultaneously controls the buzzer 12 to alarm, and how the processor 11 controls the buzzer 12 and how the controller 10 controls the alarm lamp 9 to flash and alarm according to a control instruction sent by the processor 11 belongs to the prior art, and the prior art is disclosed in a patent with the publication number of CN205327054U and is not described herein again.
The tension sensor 5 is electrically connected with the processor 11 through a lead 6, the lead 6 can be covered with the conduit 7 to protect the lead 6, and the conduit 7 can be buried underground to avoid weathering corrosion or damage by foreign objects.
The working principle is as follows: when the foundation pit 1 is displaced and deformed, the supporting and protecting plate 2 is tightly attached to the pit wall of the foundation pit 1, so that the supporting and protecting plate 2 can be displaced along with the pit wall, namely the supporting and protecting plate 2 is inclined, the supporting and protecting pile 3 is also inclined due to the inclined pushing of the supporting and protecting plate 2, the tension force borne by the pull rope 4 for connecting the inclined supporting and protecting pile 3 is changed, the tension sensor 5 can detect and transmit the changed tension force signal to the processor 11, a plurality of threshold values from low to high are preset in the processor 11, and the alarm lamp 9 and the buzzer 12 are controlled to send different alarm signals according to the magnitude of the tension force change amplitude;
for example, when the variation range of the tension is small but exceeds the preset minimum threshold value in the processor 11, the controller 10 controls the alarm lamp 9 to be turned on and not to flicker, the buzzer 12 does not work, the displacement deformation of the foundation pit 1 is not large at this time, the collapse accident cannot happen, and only the field condition needs to be manually checked in the field;
when the tension variation amplitude value is large and exceeds the intermediate threshold value, the controller 10 controls the alarm lamp 9 to light and flash, but the buzzer 12 does not work, at the moment, the displacement deformation of the foundation pit 1 is large, but still in a controllable range, the foundation pit 1 cannot immediately collapse temporarily, but the deformation position needs to be immediately reinforced;
when the pulling force amplitude of change value surpasses the maximum threshold value of predetermineeing in the treater 11, alarm lamp 9 lights the scintillation, and bee calling organ 12 works, and at this moment, foundation ditch 1 displacement deformation is very big, has the risk of collapsing at once, needs the workman to flee from foundation ditch 1 immediately.
The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of the changes or substitutions within the technical scope of the present invention, and all should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
