Embodiment 1

[0110] A tunnel project in Nyingchi, Tibet, has a total length of 4.8km. Except for the entrance section, which is constructed by conventional drilling and blasting method, the rest of the tunnel section is excavated by double-shield TBM. The diameter of the tunnel excavation section is d=8.8m. The construction period is 10 months.

[0111] Using this method to calculate the land occupation scale of the TBM precast concrete segment factory in this project mainly includes the following steps:

[0112] 1. According to the total tunnel length of 4.8km and the TBM excavation construction period of 10 months, obtain the first unknown TBM monthly average excavation footage x=480m / month involved in the present invention;

[0113] 2. According to the general situation of the project, obtain the second unknown tunnel excavation section diameter d=8.8m involved in the present invention;

[0114] 3. Substituting the two parameters of TBM monthly average excavation footage x and tunnel e...

Abstract

The invention discloses a method for rapidly determining a land occupation scale of a TBM (Tunnel Boring Machine) precast concrete duct piece factory and belongs to the technical field of civil engineering. The method comprises the following steps: firstly, comprehensively analyzing the production work efficiency of each procedure according to production data including actual work completion amount, work completion time and the like of each procedure of an existing precast concrete duct piece factory; combining requirements of safety production of each region of a duct piece prefabrication factory and related production experience and deducing a calculation formula for calculating the land occupation area of each procedure of the precast concrete duct piece factory; finally, rapidly determining the land occupation area of each procedure of the precast concrete duct piece factory according to basic parameters including a tunnel TBM tunneling construction period, an excavation section diameter and the like. According to the method provided by the invention, reference evidence is provided for rapidly determining the land occupation scale of the TMB precast concrete duct piece factory at a planning and design phase of engineering and effective guarantee is provided for follow-up construction; a condition that land occupation scale selection of the duct piece prefabrication factory is too small and the production efficiency of duct pieces is influenced can be avoided; investment wastes of factory building engineering, caused by the fact that the land occupation scale selection of the duct piece prefabrication factory is too large, are avoided.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a method for quickly determining the land occupation scale of a TBM precast concrete segment factory. Background technique [0002] Tunnel boring machine TBM (Tunnel Boring Machine) is characterized by its fast excavation speed (usually 5 to 10 times that of the conventional drilling and blasting method), one-time hole formation, and can provide a safe working environment and enable tunnel excavation, slag discharge, support With the advantages of synchronous completion of maintenance and other processes, it is being adopted by more and more tunnel projects. Among them, the production of prefabricated concrete lining segments is a very important link in TBM excavation construction. Whether the site selection and land occupation size are reasonable will directly affect the production speed of segments, and then affect the progress of TBM excavation construction, especial...
