Abstract
A foundation pit support pressure detection device comprises a clamping groove and a clamping plate embedded in the clamping groove. The foundation pit support pressure detection device is characterized in that the clamping plate is connected with a pressure monitor device; an ejector block is arranged behind the pressure monitor device; a hydraulic rod abuts against the rear portion of the ejector block; a cross beam is connected with the rear portion of the hydraulic rod; and a controller is connected with the periphery of the hydraulic rod. Compared with the prior art, the foundation pit support pressure detection device has the following advantages that through the spliced structural design, a pressure sensor and a hydraulic cylinder are arranged, pressure can be monitored and raised in real time, supporting force is increased, and a foundation pit is prevented from collapsing. The foundation pit support pressure detection device is reasonable in structural design, saves manpower and is suitable for being used and popularized.
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 by the heatable adobe sleeping platform that substrate absolute altitude and basic plane size are excavated in basic engineering position.According to geology hydrological data, in conjunction with on-the-spot nearby buildings situation, excavation plan should be determined, and performs water-proof drainage work before excavation.The not dark person of excavation by the way of putting side slope, can make Stability of Earth Slopes, and its gradient size is determined by relevant engineering discipline of executing.The comparatively dark and contiguous person that has building of excavation, available foundation pit walls supporting method, sprayed mortar wall protecting method, Large Foundation Pit even adopts diaphragm wall and the method such as colonnade formula bored pile is chain, protection outside soil layer collapse into; Nearby building is without influencer, available well point method dewatering, adopts and puts slope open cut; Natural cold air freezing process can be adopted to excavate etc. in cold district.
Deep foundation pit supporting structure is widely used at present, along with the lifting that construction technology requires for technical security, generally horizontal supporting can be adopted when deep pit digging, inwardly subside to prevent supporting and protection structure, but it is comparatively complicated for the installation and removal operation of horizontal supporting, cost is higher, and can not make real-time pressure monitor.
Summary of the invention
The present invention is directed to above shortcoming, the problem of real-time pressure monitoring can not be accomplished based on the horizontal suspension device of the existing foundation ditch of solution.Propose a kind of pattern foundation pit supporting structure pressure-detecting device, this equipment mechanism is reasonable in design, by setting pressure sensor on suspension device, accomplishes Real-Time Monitoring, reduces the generation of the cave-in accident of foundation ditch.
For realizing object of the present invention, the technical solution used in the present invention is:
A kind of pattern foundation pit supporting structure pressure-detecting device, comprise draw-in groove, be embedded in the clamp in described draw-in groove, it is characterized in that: described clamp is connected with 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, also rubber pad is accompanied between draw-in groove and clamp.
Preferentially, described hydraulic stem periphery is also overlapped and is had sleeve pipe, and described sleeve pipe extends to cross rail top and pressure monitoring device top.
Preferentially, also comprise pressure alarm, between described pressure alarm and pressure monitoring device, be connected with wire.
Compared with prior art, advantage of the present invention is as follows: by the structure design of splicing, and setting pressure sensor and hydraulic cylinder, can monitoring pressure in real time, and real time stress, increase support force, prevent foundation pit collapse.Mechanism design of the present invention is reasonable, saves manpower, is applicable to promoting the use of.

Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is described in detail.Following examples will contribute to those skilled in the art and understand the present invention further, but not limit the present invention in any form.It should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, some distortion and improvement can also be made.These all belong to protection scope of the present invention.
Embodiment 1
A kind of pattern foundation pit supporting structure pressure-detecting device, comprise draw-in groove 7, be embedded in the clamp 8 in described draw-in groove 7, described clamp 8 is connected with 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 and is used for controlling whole device.
In order to protect hydraulic stem 11 structure of self in elongation process squeezed not bad, between crossbeam 1 and hydraulic stem 11, between draw-in groove 7 and clamp 8, also accompany rubber pad 12.In the device course of work, in order to assurance device is not destroyed, hydraulic stem 11 periphery is also overlapped and is had sleeve pipe 2, and described sleeve pipe 2 extends to crossbeam 1 top and pressure monitoring device 9 top.Also comprise pressure alarm 4, between described pressure alarm 4 and pressure monitoring device 9, be connected with wire 5.
This pattern foundation pit supporting structure pressure-detecting device disclosed by the invention, operating principle is such, is fixed on by draw-in groove 7 above soldier pile 13, is connected by crossbeam 1, the both sides of crossbeam 1 are all provided with pressure monitoring device and hydraulic means, can monitor after installing device.When soldier pile 13 is subject to the lateral pressure overload of foundation ditch, pressure monitoring device 9 automatically induction send signal to pressure alarm 4 by wire 5 and report to the police.Meanwhile, controller 3 hydraulic control bar 11 extends and acts on draw-in groove 7, withstands soldier pile 13 and prevents it from collapsing, effectively prevent the generation of foundation pit collapse.
