Embodiment Construction

[0026] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] For tunnels with long-distance compound strata, the operation of shield tunneling into the warehouse (personnel pressure chamber) is an indispensable process, and it is also the only way to solve operations such as faults and tool changes in the shield machine chamber. The most effective method for clearing the geology and hydrology of the face. The invention discloses four methods for entering the shield machine: entering the shield with pressure, opening the chamber openly, opening the chamber with stratum reinforcement, and entering the chamber under low pressure with limited discharge. The specific method to choose should be determined according to the operation objectives in the warehouse and the geological and hydrological conditions of the location, such as Figure 1-Figure 6 shown. In the present invention, the ...

Abstract

The invention discloses a shield machine warehouse entry method, in order to solve the safe entry-departure warehouse problem of a shield machine. For realizing the propose, the invention discloses the shield machine warehouse entry method which comprises the following steps: A, the geohydrology information of a heading face of the shield machine is acquired; B, water stop reinforcement treatmentis carried out on the stratum of the heading face according to the geohydrology information; and C, constructors enter in the warehouse to work. The shield machine warehouse entry method discloses four warehouse entry methods according to the stratum of the shield machine particularly the hydrogeololgy condition of the heading face, can realize safe warehouse entry and departure under various conditions, and facilitate works such as tool changing in the warehouse and failure recovery and the like for constructors.

Description

technical field [0001] The invention relates to a construction method of a shield tunneling machine, in particular to a storage method of the shield tunneling machine. Background technique [0002] In recent years, my country's underwater shield tunnels have begun to develop vigorously. Although there have been many successful engineering examples of large-diameter mud-water shield tunnels in China, there are still relatively large risks in the construction of large-diameter underwater tunnels using the shield method. It is one of the biggest risks in shield construction. In the past engineering construction, there were many accidents due to the operation of entering the warehouse, and some even caused many casualties in the warehouse; but in the construction in the complex stratum, it is difficult to avoid the operation of entering the warehouse. Therefore, how to adopt corresponding measures Completing the safe entry into the warehouse is an urgent problem to be solved in ...
