Problems solved by technology

During the excavation process of the earth pressure balance shield machine, if it encounters bad geology, it is very important to excavate with a full soil warehouse; in addition, due to the uneven skills of the construction personnel, it is impossible to accurately judge whether the soil warehouse is full, and sometimes when the soil warehouse is not full. , in order to ensure the speed of excavation, the shield machine will continue to excavate. When it reaches the stratum with poor geology, landslides may occur, which may cause casualties, road interruption, and bring adverse effects and economic losses to the construction party.
At present, there is no device on how to detect whether the soil bin is full or not in China.

Embodiment Construction

[0014] like figure 1 , figure 2 , image 3 As shown, the present invention discloses a device for judging whether the earth pressure balance shield earth bin is full or not, including a pressure detection device. The signal output terminal of the sensor is connected to the host computer, and the host computer judges whether the warehouse is full, and sends an alarm signal to the alarm unit when the warehouse is not full, and the main control room will display the alarm. The pressure detecting device is an earth pressure sensor 6, or other devices for detecting pressure. The earth pressure sensor 6 is fixed on the cone plate 3 through the support 4 , and the earth pressure sensor 6 and the support 4 are connected and fixed through the bolt 5 . One end of the cone plate 3 is fixed on the upper part of the front shield 1 soil bin, and the other end is fixed on the partition 2; End cap 9, wiring port is arranged on cover plate 9. The connection wire 10 of the signal output e...

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 [0001] The invention relates to the technical field of excavation and construction of a tunnel shield machine, in particular to a device for judging whether an earth pressure balance shield earth bin is full. Background technique [0002] At present, in the shield construction of existing underground tunnel projects in China, due to the complex and diverse geology, there are various types of shield machines, among which the earth pressure balance shield machine is the most commonly used one. During the excavation process of the earth pressure balance shield machine, if it encounters bad geology, it is very important to excavate with a full soil warehouse; in addition, due to the uneven skills of the construction personnel, it is impossible to accurately judge whether the soil warehouse is full, and sometimes when the soil warehouse is not full. , in order to ensure the speed of excavation, the shield machine will continue to excavate. When it reaches the stra...
