Abstract

The invention discloses a method for dynamically measuring the deslagging amount of an earth pressure balance shield tunneling machine. The method comprises the following steps that S1, a muck conveying belt is arranged; S2, a laser scanner is installed over the climbing section of the muck conveying belt, the scanning angle of the laser scanner is determined to cover the width of the muck conveying belt, and a fan-shaped contour area is formed; S31, when the muck conveying belt is measured to idle, a laser scanner scans the fan-shaped contour area S0 of the muck conveying belt in unit time t,and the fan-shaped contour area S0 is recorded as a system calibration value; S32, when the muck conveying belt conveys muck, a laser scanner scans the fan-shaped contour area S of the muck conveyingbelt in unit time t; S33, obtaining the slag amount according to the result; wherein v is the conveying speed of the muck conveying belt. The device has the advantages of being easy to obtain and install and convenient to maintain later.

Description

technical field [0001] The invention relates to the field of shield tunnel construction. More specifically, the invention relates to a method for dynamically measuring the amount of slag discharged by an earth pressure balance shield machine. Background technique [0002] With the continuous acceleration of my country's urbanization process, the shield method has been widely used in the construction of urban subways and municipal tunnels. The shield machine is a multi-functional and integrated modern mechanical equipment with a high degree of automation. The slag output of the shield machine during the excavation process is an important parameter, and controlling the slag output is one of the key technologies of the shield machine; over-excavation of the earthwork will lead to excessive ground loss and cause surface settlement, while under-excavation of the earthwork will cause soil The rise of the cabin pressure causes the ground to rise, and the control of the amount of ...
