Description

The sedimentation real-time monitoring system

Technical field

The utility model relates to a kind of face of land and attachment settlement monitoring system thereof, relates in particular to a kind of system that can monitor the face of land and attachment sedimentation thereof in real time.

Background technology

The building Geotechnical Engineering is one of present important industry of China.In the excavation construction of structure foundation, the sedimentation situation of in real time, accurately monitoring the working-yard surrounding building is significant for safety in production.

At present, generally all be to adopt spirit-leveling instrument to come the sedimentation situation of periodic monitor buildings by professional survey crew.This is a kind of classic method, exists following shortcoming:

1. real-time is poor.In work progress, be difficult to carry out continuous monitoring.

2. repetitive error is big.

3. can't get rid of human factor to the negative effect of monitoring accuracy.

The utility model content

The purpose of this utility model is, provide a kind of can the automatic continuous monitoring face of land and the system of attachment sedimentation, have the advantages that real-time is good, precision is high.

The utility model adopts fluid connection device principle to monitor the sedimentation situation of buildings, can satisfy that real-time is good, precision is high, designing requirement that can automatic continuous monitoring.

Details are as follows for monitoring principle:

Make earlier two liquid storage cylinders (below be referred to as to detect tube), select monitoring point, two faces of land again, one is the A point, and another is the B point.Detect tube with two and be separately fixed on these two Ground Point, the tube end, be communicated with pipeline, injects an amount of liquid again in tube.The detection tube that is fixed on the A point is called the A tube, and the detection tube that is fixed on the B point is called B tube (as illustrated in fig. 1 and 2).

According to law of connected vessels, the fluid level (being A and the B among Fig. 1 and 2) in two should remain on the same surface level.

Before if sedimentation takes place the B point, liquid level is respectively H1 and h1 in A tube and the B tube, as shown in Figure 1; After sedimentation took place the B point, liquid level was for being respectively H2 and h2, as shown in Figure 2 in A tube and the B tube.So, the relative A of the B point vertical sedimentation of ordering can be represented by the formula apart from S:

S＝(h2-H2)-(h1-H1)＝(h2-h1)-(H2-H1)＝Δh-ΔH

Wherein: Δ h=h2-h1 is the liquid level variable quantity of B tube

Δ H=H2-H1 is the liquid level variable quantity of A tube

Δ h and Δ H can detect continuously by liquid level sensor.Just can monitor in real time the vertical sedimentation amount that B point in the face of land is ordered with respect to A accordingly.

In actual applications, a plurality of monitoring points and the corresponding tube that detects can be set, can realize that like this multiple spot is to the monitoring of any or the relative settlement amount between any 2.

Below be two types settling amount monitoring:

1. absolute settlement amount monitoring

If with a bit being arranged on certain reference point away from the monitored area in a plurality of monitoring points, then can monitor all the other monitoring points with respect to the settling amount of reference point, it also is the absolute settlement amount.This scheme is applicable to spacious zone, as: the zone that railway is along the line, subsidence area, mine, high ferro bridge pier etc. are easy to lay fluid pipeline.

2. non-uniform settling amount monitoring

In the excavation construction of City Building ground, can some monitoring points be set in the top of foundation ditch periphery important building thing, form a monitoring system, in order to monitor the non-uniform settling of this buildings in work progress, also be tilt condition.

The technical solution of the utility model is as follows:

A kind of sedimentation real-time monitoring system is selected some monitoring points in the monitored area, fixed test tube on it, and all detect and to be interconnected by pipeline between the tube and to pack appropriate amount of fluid into;

Each detects in the tube liquid level sensor is installed, the preferred magnetostrictive liquid level sensor of liquid level sensor, and liquid level sensor has communication interface, connects with the on-site supervision system by the communication bus cable;

The on-site supervision system has following function:

1. regularly send data acquisition command to each liquid level sensor that detects tube,

2. the receiving sensor liquid level data of sending,

3. data are handled, are calculated settling amount, judge whether and should report to the police,

4. show settling amount, output sound and light alarm signal,

5. the historical data of observation process stored in record, so that the summary of analysis from now on, thereby further raising is for the prediction level of accident.

Further, also comprise signal sending end and remote signal receiving end, the on-site supervision system connects with signal sending end, and signal sending end is transferred to the remote signal receiving end with detected data and warning message.

Further, also comprise long distance control system, the remote signal receiving end connects with long distance control system.

Further, described signal sending end is industrial mobile phone, and signal sending end transmits data to the remote signal receiving end by wireless communication networks.

The utlity model has following technique effect:

1. can detect the sedimentation parameter of some monitoring points automatically, continuously, in real time;

2. detected parameter and setup parameter can be compared in real time, note abnormalities and in time report to the police;

3. can utilize existing wireless communication networks, with detected data and warning message remote transmission.
