Embodiment Construction

[0023] A parallel construction method for connecting passages in mudstone strata of urban subways and shield excavation, such as figure 1 , 2 , 3, including the following steps:

[0024] Step 1. Temporary support and reinforcement at the opening of the communication channel

[0025] A. After the initial tunnel shield 1 passes through the communication channel 2, supplementary grouting is carried out at the back of the 10-ring segment before and after the communication channel; B. The well-shaped frame 3 is used to support the segment at the opening of the communication channel, and in the well The upper step construction platform 4 and the lower step construction platform 5 of the communication channel are set up on the word frame; C, after the main engine of the tunnel shield 6 in the later stage passes through the communication channel, it immediately opens the opening of the communication channel with a drilling core puller in the initial departure tunnel D. When the init...

Abstract

The invention relates to the field of tunnel shield construction, in particular to an urban subway mudstone stratum connected aisle and shield tunneling parallel construction method, and solves the problems that due to the adoption of a blasting method in the prior art, the period is long, traffic recovery is delayed, interference to shield tunneling is generated and the blasting method and the shield tunneling cannot be constructed in parallel. The urban subway mudstone stratum connected aisle and shield tunneling parallel construction method comprises the following steps of: carrying out temporary supporting and reinforcement at an opening of a connected aisle; constructing upper steps of the connected aisle; constructing lower steps of the connected aisle; and carrying out second liner construction. A construction platform which is temporarily erected is sufficiently utilized and an air compressor is arranged in a station to provide the air pick excavating condition for the connected aisle and reduce interference to shield tunneling; a roller is welded under a conventional conveying pump and a rail concrete tank wagon is applied to rapidly carry out concreting when shield tunneling is shut down to carry out repair and maintenance. The urban subway mudstone stratum connected aisle and shield tunneling parallel construction method has the advantages of simple process, advanced technology, flexible process arrangement, strong practicality, shortening of the construction period and the like, a gap of an urban subway mudstone stratum connected aisle and shield tunneling parallel construction technology in China is filled and excellent economic benefits and social benefits can be obtained.

Description

technical field [0001] The invention relates to the technical field of tunnel shield construction, in particular to a method for parallel construction of an urban subway mudstone stratum communication channel and shield excavation. Background technique [0002] Communication channel construction is usually carried out in shield tunneling projects, so that during subway operation, when a fire or accident occurs in one of the interval tunnels, passengers can immediately and safely evacuate to another tunnel through the set communication channel. With the rapid development of my country's urban subway construction, the shield method tunnel construction technology has been widely promoted and applied due to its unique characteristics and advantages such as intelligence, safety, and speed. However, the key process that most restricts the opening of shield tunnels is the construction of communication channels. At present, the connection channel of subway mudstone shield tunnels ...
