Abstract
The invention discloses a device judging whether or not an earth pressure balance shield earth chamber is full. The device comprises a pressure detector disposed on the upper portion of a front shield earth chamber of the earth pressure balance shield; the signal output end of a pressure sensor is connected with an upper computer; the upper computer judges whether or not the chamber is full; if not, a warning signal is sent to an alarm unit. The device has the advantages that whether or not the earth chamber is full can be judged anytime during earth pressure balance shield tunneling, full-chamber shield tunneling can be ensured and the application of full-chamber tunneling decreases the danger of collapse ahead.
Description
Technical field
The present invention relates to a kind of tunnel shield machine tunneling technique field, be specifically related to a kind of device for judging whether earth pressure balanced shield, EPBS Tu Cang buys securities with all one's capital.
Background technology
At present, in existing subterranean tunnel Project Shield construction, because complicated geology is various, shield machine should have polytype mutually at home, and balancing earth-pressure shielding machine is wherein the most frequently used one.Balancing earth-pressure shielding machine driving process in, if run into unfavorable geology, Tu Cang buy securities with all one's capital driving most important; In addition, because constructor's technology is very different, cannot judge accurately whether Tu Cang buys securities with all one's capital, sometimes Tu Cang less than time, be guarantee driving speed, shield machine still can continue driving, arrive the not good stratum of geology, just may occur landslide, may cause casualties, road interrupts, and brings harmful effect and economic loss to construction party.The domestic device of whether buying securities with all one's capital about how detecting Tu Cang that there is not yet at present.
Summary of the invention
The object of this invention is to provide a kind of device for judging whether earth pressure balanced shield, EPBS Tu Cang buys securities with all one's capital, judge by detecting the pressure at Tu Cang top whether Tu Cang buys securities with all one's capital, can guarantee the balancing earth-pressure shielding machine driving of buying securities with all one's capital.
The present invention adopts following technical proposals: a kind of device for judging whether earth pressure balanced shield, EPBS Tu Cang buys securities with all one's capital, include pressure-detecting device, described pressure-detecting device is arranged on earth pressure balanced shield, EPBS anterior shield Tu Cang top, the signal output part of pressure sensor connects host computer, the host computer judgement of whether buying securities with all one's capital is not to send alarm signal to alarm unit when buying securities with all one's capital.
Described pressure-detecting device is fixed on cone-plate by bearing, and described cone-plate one end is fixed on anterior shield Tu Cang top, and the other end is fixed on dividing plate.
Described pressure-detecting device and bearing are bolted fixing.
On described dividing plate, be provided with connection jaws bearing, connection jaws bearing is bolted end cap, has connection jaws on cover plate, and the connecting line of the signal output part of described pressure-detecting device is drawn connection host computer by the connection jaws arranging on end cap.
Described pressure-detecting device is arranged on Huo Xie top, the positive top of earth pressure balanced shield, EPBS anterior shield Tu Cang.
Described pressure-detecting device is soil pressure case or other pressure-detecting device.
The present invention can be in the time that earth pressure balanced shield, EPBS tunnels, and judges at any time whether Tu Cang buys securities with all one's capital, and in not buying securities with all one's capital, sends alarm signal, and warning operating personnel can guarantee the shield structure driving of buying securities with all one's capital, and can reduce the danger that front caves in.The present invention can increase work efficiency, simple in structure, easy to operate, economical and practical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 be in Fig. 1 A to structural representation;
Fig. 3 is the local enlarged diagram of I part of Fig. 1.
The specific embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, the invention discloses a kind of device for judging whether earth pressure balanced shield, EPBS Tu Cang buys securities with all one's capital, include pressure-detecting device, described pressure-detecting device is arranged on earth pressure balanced shield, EPBS anterior shield Tu Cang top, the signal output part of pressure sensor connects host computer, the host computer judgement of whether buying securities with all one's capital, is not to send alarm signal to alarm unit when buying securities with all one's capital, and master-control room can display alarm.Described pressure-detecting device is soil pressure case 6, or the device of other detected pressures.Described soil pressure case 6 is fixed on cone-plate 3 by bearing 4, and described soil pressure case 6 and bearing 4 are connected and fixed by bolt 5.Described cone-plate 3 one end are fixed on anterior shield 1 Tu Cang top, and the other end is fixed on dividing plate 2; On described dividing plate 2, be welded with connection jaws bearing 7, on connection jaws bearing 7, connect end cap 9 by bolt 8, on cover plate 9, have connection jaws.The connecting line 10 of the signal output part of described soil pressure case 6 is drawn connection host computer by the connection jaws arranging on end cap 9.
Wherein said pressure-detecting device can be arranged on Huo Xie top, the positive top of earth pressure balanced shield, EPBS anterior shield Tu Cang.
When shield structure is in the time normally tunneling, the soil pressure signal detecting in native storehouse by soil pressure case 6 carries out Real-Time Monitoring, and by connecting line 10, the data that record is passed on host computer, and host computer is in conjunction with known shield machine parameter and construction geology parameter, contrast, confirm whether Tu Cang buys securities with all one's capital.Judgement according to being to determine according to operation driver's experience and actual geology because geology is of all kinds, pressure is also different.Can be quick, safe in the time that Tu Cang buys securities with all one's capital construct, has reduced the danger of landslide, in the time that Tu Cang does not buy securities with all one's capital, sends alarm signal, warning operating personnel.
Above embodiment is only for illustrating preferential embodiment of the present invention; but the present invention is not limited to above-mentioned embodiment; in the ken possessing at described field those of ordinary skill; any modification of doing within the spirit and principles in the present invention, be equal to and substitute and improvement etc., within it all should be encompassed in the technical scheme scope of request protection of the present invention.
