Abstract

The utility model discloses an integrated system for measuring the non-uniform settlement of a building foundation and belongs to the field of building detection. The integrated system comprises a detection unit, a transport unit and a calculation and control unit. The transport unit is respectively connected with the detection unit and the calculation and control unit. The integrated system is suitable for all artificial buildings comprising hydraulic building foundations, highway and railway bridge piers and abutments, wind power foundations, high-rise building foundations, towering building foundations and the like. All the buildings which possibly have the problem of non-uniform settlement to cause a serious result can be subjected to early warning and processing by the system.

Description

Measure the integral system of building foundation non-uniform settling

Technical field

The utility model relates to a kind of integral system of measuring the building foundation non-uniform settling.

Background technology

Nearly all artificial structure is located on the foundation.Various loads in the self gravitation of these buildingss and the physical environment can directly be transferred on its basis, are carried by the basis.

The basis itself is the part of buildings, and it is located on the ground, can be because the uneven sedimentation of the inhomogeneous generation of bearing capacity of stressed inhomogeneous or ground.A lot of artificial structures' damage in the world, the overwhelming majority are because foundation uneven settlement causes, and therefore, can effectively observe the foundation non-uniform settling seem very necessary.

The non-uniform settling on basis is that when receiving buildings pressure, the uneven subsidence of underground foundation causes owing to present position, building foundation ground.Comparatively speaking, we think that buildings itself is a rigidity, and itself does not deform reinforced concrete, and the inhomogeneous buildings that caused of its ground tilts to certain direction.

As shown in Figure 1, our known building foundation width is A, is α if measure this tilt variation angle, then non-uniform settling value H=cot ∠ α * A.

The traditional observation procedure of non-uniform settling on basis is, horizontal observation station is set around in the building foundation, establishes level observation basic point in the position of leaving buildings.Regularly with the discrepancy in elevation of these observation stations of level measurement with respect to basic point.Relatively, obtain the settlement values with respect to basic point, analyze these sedimentation values, whether the force-bearing situation that just can know buildings safety, proposes to keep in repair and remedial measures.

But therefore traditional observation procedure usually can not carry out early warning because level measurement lacks continuity and high precision property before foundation uneven settlement takes place.

Summary of the invention

Weak point to above-mentioned prior art existence; The purpose of the utility model just is to provide a kind of integral system of measuring the building foundation non-uniform settling; The integral system of this measurement building foundation non-uniform settling utilizes modern technology of Internet of things; Digitized processing is carried out at the inclination angle of xy direction, converted to digital signal, be transferred to the Internet of Things cloud computing server through modern communications technology (zigbee, gprs, 3G) then.

The technical scheme of the utility model is: a kind of integral system of measuring the building foundation non-uniform settling; This integral system comprises detecting unit, delivery unit and calculating and control module, and said delivery unit is connected with said calculating and control module with said detecting unit respectively.

As preferably, said detecting unit is the angle of bank measurement sensor.

As preferably, said angle of bank measurement sensor is the twin shaft angular transducer.

As preferably, said delivery unit is earlier via after the zigbee wireless data transmission, is transferred to said calculating and control module through gprs and 3G again.

As preferably, said calculating and control module are the Internet of Things cloud computing server.

Compared with prior art; The utility model utilizes modern technology of Internet of things; Digitized processing is carried out at the inclination angle of xy direction, converted to digital signal, be transferred to the Internet of Things cloud computing server through modern communications technology (zigbee, gprs, 3G) then; Thereby the realization continuous monitoring is carried out early warning before foundation uneven settlement takes place.

Fig. 2 is the overall schematic of the utility model.

Embodiment

To combine accompanying drawing that the utility model is described further below.

The integral system of measurement building foundation non-uniform settling as shown in Figure 1, this integral system comprises detecting unit, delivery unit and calculating and control module, delivery unit is connected with calculating and control module with detecting unit respectively.

Detecting unit is the angle of bank measurement sensor, is preferably the twin shaft angular transducer.

The twin shaft angular transducer carries out data acquisition to each monitoring point.

First from the information that the twin shaft angular transducer is collected via after the zigbee wireless data transmission, be transferred to the Internet of Things cloud computing server through gprs and 3G again.

The Internet of Things cloud computing server puts these data and handle in storage; The inclination angle changed is provided with the early warning threshold values, when angle value surpasses threshold values, when just buildings might be caused danger; Cloud computing server can send early warning automatically, notifies the related personnel to take measures.

Native system is applicable to all artificial structures: comprise that hydraulic structure basis, road and rail bridge pier, wind-powered electricity generation basis, high-rise are basic, high-rise structures basis etc.; All non-uniform settlings that might take place cause serious consequence, can come early warning and processing with the method.
