Description
Technical field
The utility model belongs to constructing metro tunnel technical field, is specifically related to a kind of Metro station excavation construction dangerous automatic warning device that caves in.
Background technology
In Metro station excavation work progress, because subway cave-in accident causes many people injures and deaths and property loss, therefore, the safety problem in work progress is extremely important.The safety measure of generally taking is at present to utilize around existing building composition deformation, underground water, solum settlement, and go along with sb. to guard him self and carry out safety monitoring, lay earth pressure cell, inclinometer, deep settlement mark, reinforcement stresses meter and carry out survey data, its monitoring point distributes comparatively sparse, monitored data is isolated, and need every day special messenger to check, once occur that data exception stops construction, does not set up the system of a set of real-time monitoring; Meanwhile, because regularly check every day, delayed the time of getting rid of hidden danger.This kind of mode, because the standard of forecast is too general, enough warns to administrative staff, causes idea of leaving things to chance, easily causes failing evacuating in time, causes casualties.Therefore, studying and a kind ofly can cave in and carry out dangerous automatic early-warning and device simple to operate Metro station excavation construction, be necessary for guaranteeing the personal security of work progress and increasing work efficiency.
Summary of the invention
The defect or the deficiency that for above-mentioned prior art, exist, the purpose of this utility model is, a kind of Metro station excavation construction dangerous automatic warning device that caves in is provided, this device has solved in prior art and has arranged a large amount of manpower regularly to check every day, and the time of having delayed eliminating hidden danger causes dangerous problem.The utility model can be monitored also automation and the informationization of early warning and monitoring engineering to work progress automatically, guarantees subway foundation pit safe construction.
In order to achieve the above object, the technical scheme that the utility model adopts is as follows:
The construction dangerous automatic warning device that caves in, comprises casing, and strain gauge, data processor and data display instrument are installed on the base plate of casing; The side plate of the corresponding casing of display floater of data display instrument is provided with opening; Casing outside is provided with alarm bell; Data display instrument is connected with alarm bell; Data display instrument is connected by data processor with strain gauge.
The utility model also comprises following other technologies feature:
Described device also comprises a computer, and computer is connected with data display instrument.
Described computer is connected with printer.
The top board of described casing is detachable.
Detachable between each side plate of described casing and adjacent side plates; Each side plate and the base plate all hinged side plate that makes can outwards open.
The top board of described casing is provided with handle.
The beneficial effects of the utility model are:
Automatically the change procedure that object of observation is complete is recorded in monitoring continuously, and obtains in real time observation data, has realized overall process is monitored in real time, and security performance accesses assurance.By network system, data are sent to the department that other need data, compare with existing personal monitoring, automatically monitoring does not need personnel to measure, the setting work of system data can complete in the working design stage, in use after energising, can accomplish does not need special messenger to nurse, and can save a large amount of manpower.This device has been realized directly and has been estimated and obtained data by digital display instrument, also can judge by alarm bell alarm sound, is applicable to noisy tunnel construction environment.
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Number in the figure implication: 1, alarm bell, 2, strain gauge, 3, data processor, 4, data display instrument, 5, probe, 6, casing, 7, computer.
The specific embodiment
As shown in Figure 1, the Metro station excavation of the present utility model construction dangerous automatic warning device that caves in, comprises casing 6, and strain gauge 2, data processor 3 and data display instrument 4 are installed on the base plate of casing 6; The side plate of the corresponding casing 6 of display floater of data display instrument 4 is provided with opening; Casing 6 outsides are provided with alarm bell 1; Data display instrument 4 is connected with alarm bell 1; Data display instrument 4 is connected by data processor 3 with strain gauge 2.
Data display instrument 4 can be connected with a computer 7, and real-time recorded data is as the reference of construction in the future, and computer 7 can be prepared printer to obtain graphic documentation intuitively.
The soil layer that strain gauge 2 is used for gathering a certain measuring point in load bearing wall changes displacement;
Data display instrument 4 is used to provide the platform that testing staff inputs threshold value.
In the present embodiment, each parts Choice and design is as follows:
Data display instrument 4 adopts NPXM-2011P5N type data display instrument;
The top board of casing 6 is detachable, and top board is provided with handle; Detachable between each side plate of casing 6 and adjacent side plates; Each side plate and the base plate all hinged side plate that makes can outwards open.It is in order to be put down in use, to expose probe that casing 6 side plates are all made movable.When carrying, side plate to be holded up and fixed and top board is loaded onto, probe 5 is avoided extraneous factor and is disturbed in casing 6 inside, chest is carried and into building site, used, and does not need additionally equipment to be taken out and Installation and Debugging, saves time and also can guarantee the accuracy of equipment.
The course of work of the present utility model:
When the utility model is applied in Metro station excavation construction, a plurality of measuring points are set on load bearing wall, each measuring point needs a set of prior-warning device of the present utility model.During to each measuring point actual measurement, casing 6 is opened, tester sets displacement threshold value by data display instrument 4, then the probe of strain gauge 25 is embedded in its corresponding measuring point, the soil layer that strain gauge 2 is measured its corresponding measuring point in real time changes displacement, and sends to data processor 3, the data that data processor 3 is sent strain gauge 2 and data display instrument 4 compare, if displacement surpasses threshold value, data processor 3 sends control signal to alarm bell 1, and alarm bell 1 is reported to the police.With this, guarantee that each measuring point is monitored, guarantee the safety of work progress.
Threshold value in data display instrument 4 is divided into two kinds: it is abnormal that one is that early warning warns corresponding measuring point monitored data, and related personnel need to investigate corresponding location; It two warn staff and should withdraw immediately for alarm, and the difference of sounding when the two can be reported to the police by alarm bell is distinguished.
