Utility model content
In order to solve problems of the prior art, the utility model provides a kind of prior-warning device of monitoring foundation pit deformation, overcomes monitoring method in prior art inaccurate, can not the problem of Real-Time Monitoring, in time early warning.
The technical solution of the utility model is:
A kind of prior-warning device of monitoring foundation pit deformation, comprise Support Steel sheet pile, draw anchor steel sheet pile and draw anchor wire rope, it is characterized in that, the described anchor wire rope that draws is two, steel cable one end connects tensiometer, the other end connects Support Steel sheet pile and encloses purlin place, second wire rope one end connects tensiometer, anchor steel sheet pile is drawn in other end connection, described tensiometer is provided with contact and scale, and can preset warning threshold, tensiometer is connected with alarm by circuit, when tensiometer is subjected to displacement and reaches threshold, contact pad can be reported to the police.
Describedly draw anchor wire rope every section of junction to be all provided with six buckles firmly to fix.
Described transformer is voltage is 24V.
Described alarm circuit is connected to transformer.
Described tensiometer is provided with fixed touch plate and slip contact, slip contact is connected with alarm zero line, and the live wire of alarm is connected with transformer positive pole, and transformer negative pole is connected with fixed touch plate.
The beneficial effects of the utility model are:
(1) construction cost is saved
After autoalarm is communicated with, only need make regular check on, reduce monitoring person works amount, during work, one people can operate, and has saved construction cost.
(2) safe and reliable
A whole set of warning system adopts 24V safe voltage, and tensiometer increases contact through repacking, and when value of thrust reaches design load, the contact generation current that contacts is reported to the police immediately, and after alarm sends the sound, in foundation ditch, operating personnel withdraws rapidly, greatly can improve working security.
(3) report to the police rapidly in time
Common pit retaining monitoring cannot make warning rapidly, but judged by data analysis, this cover foundation ditch prior-warning device, by setting warning value of thrust in advance, when reaching the work of warning value of thrust alarm device turn-on current, send the sound, pre-warning time shortens greatly, reaches Real-Time Monitoring deep pit monitor state.
The utility model is applicable to drawing outside steel sheet pile the deep foundation ditch of anchor Support types to monitor, foundation ditch adopts steel sheet pile supporting, anchor is drawn outside wire rope, it is solid that hoisting cable anchorage section sets isosceles triangle piled anchor, Real-Time Monitoring steel sheet pile deflection deformation situation and wire rope can draw anchor axle power situation of change, deep foundation ditch safety monitoring is required that work items controlled continuously can be applicable.
