Problems solved by technology

[0004] Usually, the soil discharge volume of the mud-water shield is to measure the flow rate and density in the pipe according to the results of the geotechnical test, the flow meter and the density meter on the mud discharge pipe, etc., and then calculate the soil discharge volume, but because the density meter installed on the pipeline is usually Using a nuclear radiation density meter requires complex procedures for use, and the country has strict regulations on the storage and use of radioactive materials, so most muddy water shield equipment is not equipped with this device

Embodiment Construction

[0023] With reference to figure, the present invention is muddy water shield earthwork survey management method, comprises the following steps:

[0024] 1) During mud-water shield construction, the earth excavated by the shield equipment is mixed with the mud and then transported to the ground separation equipment through pipelines. The separation equipment separates the earth into muck 2 and mud. The muck 2 is stored on the ground site, and the mud is discharged to mud pool;

[0025] 2) The mud measuring system measures the volume and specific gravity of the mud discharged from the separation equipment;

[0026] 3), the 3D laser scanner 3 measures the volume of the muck 2;

[0027] 4) The mud measurement system and 3D laser scanner 3 transmit the measurement data to the computer in real time;

[0028] 5) The computer analyzes the volume of the muck 2 to obtain the weight, analyzes the volume, specific gravity and original density of the mud to obtain the weight of the muck ...

Abstract

The invention discloses a slurry shield earthwork measurement management method. According to the method, the muck volume is analyzed through a 3D laser scanner, the volume of slurry drained by separation equipment and specific gravity change are measured through a slurry measurement system, through mathematics conversion, soil disposal amount can be acquired without utilizing a nuclear radiation densitometer, a problem of large use difficulty of special equipment because of national control is solved, the measurement management method is taken as beneficial supplement of a shield construction monitoring system, a high-level automation monitoring and measurement result is displayed in real time, and an operator is facilitated to effectively manage shield construction soil disposal conditions. The method is applied to the subway tunnel construction field.

Description

technical field [0001] The invention relates to the field of subway tunnel construction, in particular to a method for measuring and managing muddy water shield discharge volume. Background technique [0002] The shield method is currently the mainstream construction method for urban subway tunnel construction. The shield equipment commonly used is divided into two types: earth pressure balance shield machine and mud-water balance shield machine. In shield construction, the soil displacement is one of the important means to judge whether there is over-excavation and monitor whether the excavation surface is stable. [0003] In the earth pressure balance shield, the muck excavated by the shield is put into the muck truck through the screw machine and the belt conveyor. Since the volume of the muck truck is easy to measure and the volume is fixed, the construction of the earth pressure balance shield machine The data of medium displacement can be obtained by counting the numb...
