Abstract
A kind of pattern foundation pit supporting structure pressure-detecting device, including draw-in groove, it is embedded in the clamp in described draw-in groove, it is characterized in that: connecting on described clamp has pressure monitoring device, pressure monitoring device rear is provided with jacking block, hydraulic stem withstands on jacking block rear, and crossbeam is connected to described hydraulic stem rear, and it is peripheral that controller is connected to described hydraulic stem.Compared with prior art, advantages of the present invention is as follows: is designed by the structure of splicing, installs pressure transducer and hydraulic cylinder, can be with monitoring pressure in real time, and real time stress increases support force, prevents foundation pit collapse.Mechanism of the present invention is reasonable in design, saves manpower, is suitable for promoting the use of.
Description
Technical field
The invention belongs to Base hole supporting technology field, be specifically related to a kind of pattern foundation pit supporting structure pressure-detecting device.
Background technology
Foundation ditch is the heatable adobe sleeping platform excavated by substrate absolute altitude and basic plane size in basic engineering position.Should be according to geology hydrological data before excavation, in conjunction with on-the-spot nearby buildings situation, determine excavation plan, and perform water-proof drainage work.The deep person of excavation can make Stability of Earth Slopes with putting the way of side slope, and its gradient size is determined by relevant engineering discipline of executing.Excavation is relatively deep and the neighbouring person that has building, available foundation pit walls method for protecting support, gunite concrete wall protecting method, and Large Foundation Pit even uses diaphram wall and the method such as colonnade formula cast-in-situ bored pile is chain, outside protection soil layer collapse into；Nearby building is without influencer, available well-point method lowering of watertable, uses and puts slope open cut；Natural cold air freezing process excavation etc. can be used at cold district.
Deep foundation pit supporting structure has been widely used, lifting technical security required along with construction technology, horizontal supporting typically can be used when deep pit digging, to prevent supporting construction from inwardly subsiding, but installation and dismounting operation for horizontal supporting are complex, relatively costly, and real-time pressure monitor can not be made.
Summary of the invention
The present invention is directed to disadvantage mentioned above, based on solving the problem that the horizontal suspension device of existing foundation ditch can not accomplish real-time pressure monitoring.Proposing a kind of pattern foundation pit supporting structure pressure-detecting device, this equipment mechanism is reasonable in design, by suspension device pressure transducer installed above, accomplishes to monitor in real time, reduces the generation of the cave-in accident of foundation ditch.
For realizing the purpose of the present invention, the technical solution used in the present invention is:
A kind of pattern foundation pit supporting structure pressure-detecting device, including draw-in groove, it is embedded in the clamp in described draw-in groove, it is characterized in that: connecting on described clamp has pressure monitoring device, pressure monitoring device rear is provided with jacking block, hydraulic stem withstands on jacking block rear, and crossbeam is connected to described hydraulic stem rear, and it is peripheral that controller is connected to described hydraulic stem.
Preferentially, between described crossbeam and hydraulic stem, rubber blanket between draw-in groove and clamp, is also accompanied.
Preferentially, described hydraulic stem periphery is also cased with sleeve pipe, and described sleeve pipe extends to cross rail top and pressure monitoring device top.
Preferentially, also including pressure alarm, being connected between described pressure alarm and pressure monitoring device has wire.
Compared with prior art, advantages of the present invention is as follows: is designed by the structure of splicing, installs pressure transducer and hydraulic cylinder, can be with monitoring pressure in real time, and real time stress increases support force, prevents foundation pit collapse.Mechanism of the present invention is reasonable in design, saves manpower, is suitable for promoting the use of.
Accompanying drawing explanation
The most next the accompanying drawing by means of embodiment carries out brief description to the present invention.In accompanying drawing:
Fig. 1 shows the structural plan of pattern foundation pit supporting structure pressure-detecting device of the present invention；
Fig. 2 shows schematic diagram when the present invention constructs.
In figure: 1, crossbeam, 2, sleeve pipe, 3, controller, 4, pressure alarm, 5, wire, 7, draw-in groove, 8, clamp, 9, pressure monitoring device, 10, jacking block, 11, hydraulic stem, 12, rubber blanket, 13, support pile.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following example will assist in those skilled in the art and are further appreciated by the present invention, but limit the present invention the most in any form.It should be pointed out that, to those skilled in the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement.These broadly fall into protection scope of the present invention.
Embodiment 1
A kind of pattern foundation pit supporting structure pressure-detecting device, including draw-in groove 7, it is embedded in the clamp 8 in described draw-in groove 7, connect on described clamp 8 and have pressure monitoring device 9, pressure monitoring device 9 rear is provided with jacking block 10, hydraulic stem 11 withstands on jacking block 10 rear, and crossbeam 1 is connected to described hydraulic stem 11 rear, and controller 3 is connected to described hydraulic stem 11 periphery for controlling whole device.
In order to protect hydraulic stem 11 structure of self in elongation process the most squeezed bad, between crossbeam 1 and hydraulic stem 11, between draw-in groove 7 and clamp 8, also accompany rubber blanket 12.In device work process, in order to ensure that device is not destroyed, hydraulic stem 11 periphery is also cased with sleeve pipe 2, and described sleeve pipe 2 extends to crossbeam 1 top and pressure monitoring device 9 top.Also including pressure alarm 4, being connected between described pressure alarm 4 and pressure monitoring device 9 has wire 5.
This pattern foundation pit supporting structure pressure-detecting device disclosed by the invention, operation principle is such, is fixed on by draw-in groove 7 above support pile 13, is connected by crossbeam 1, the both sides of crossbeam 1 are designed with pressure monitoring device and hydraulic means, can be monitored after installing device.When support pile 13 is transshipped by the lateral pressure of foundation ditch, pressure monitoring device 9 automatically senses and passes through wire 5 and transmits a signal to pressure alarm 4 and report to the police.Meanwhile, controller 3 controls hydraulic stem 11 and extends and act on draw-in groove 7, withstands support pile 13 and prevents it from collapsing, is effectively prevented the generation of foundation pit collapse.
