Background technology
Shield machine (development machine) utilizes pressure equilibrium (medium has soil pressure, air pressure, mud hydraulic pressure) to prevent that face from caving in; Sedimentation after the anterior land subsidence of control shield machine, control are annotated synchronously pressure controlled shield machine and pass through is so soil pressure sensor, grouting pressure sensor are the basic security guarantees of shield construction.Early stage, the shield structure was mainly constructed at shaly formation, and the soil of cutting medium as balance in native storehouse mainly is a silt particle, impacted with abrasion less relatively.Along with the development of shield construction, the rock stratum of Fu Shui, sandy gravel stratum also adopts shield construction.
As shown in Figure 1; Traditional soil pressure, grouting pressure sensor are displacement backward behind main stress element 1 pressurized in the cylindrical shell 2; Pressure is passed to the liquid medium (silicone oil) 3 of power transmission, and silicone oil passes to first flexible member, 4, the first elastic elements 4 with pressure and is connected with first pressure sensing cell 5; First pressure sensing cell 5 passes to first circuit board 6 through circuit with pressure, and first circuit board 6 converts current signal output to.
The subject matter that traditional soil pressure, grouting pressure sensor run in the construction of the stratum of complicated geology is: after 1, the main stress element is being impacted, can not return to original position, sensor failure; 2, the liquid medium of power transmission is revealed, and contaminated environment causes measuring inaccurate.
Therefore, provide a kind of and can be good at stressed resetting, and do not pollute the environment, the shield machine soil pressure of long service life, grouting pressure sensor, be a urgent problem.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art; The invention provides a kind of; New soil pressure case adopts new pressure sensitive to form new circuit; The transmitting portions and the elastic body of main stress element, power are adopted rigid attachment (real is one), fundamentally solve the above two kinds of failure modes of traditional sensors.In order better to adapt to the operating mode of various complicacies; Force-summing element is adopted different cross sections with the transmitting portions of power; Both guaranteed the precision of sensor; Guarantee that again the main stress element that sensor contacts with measuring media has enough thickness, the sensor that effectively guarantees is worked in different media can both be arranged very long serviceable life.
