example

[0035] Changsha Metro Line 2 has three sections in standard 7, which need to pass twice. They are Furong Square Station and Wuyi Square Station. Since Furong Square Station is 142 meters long, the left line adopts the traditional method of station floor construction and crossing. , the whole station-crossing time is 32 days, and the right line has only used 12 days to pass the station by adopting the method of the present invention because the station-passing conditions are provided in advance.

[0036] The construction of Wuyi Square Station was completed ahead of schedule. The length of the station is 184 meters. Among them, there is still a 92-meter section of open excavation on the left line, and the length of the crossing station is 376 meters. The realization of the second initiation fully proves that the method of the present invention has strong applicability.

[0037] At present, the urban subway shield method basically adopts station passing. There are more than 30 m...

Abstract

The invention relates to the field of tunneling shield construction, in particular to a roller guide rail station-passing construction method of a whole shield machine and solving the problems of high difficulty, high cost, long construction peroid and the like of the traditional method. The roller guide rail station-passing construction method comprises the following steps of: machining a shieldforward-moving roller, a forward-moving guide rail, a counter-force device and a rear matched track section; determining whether water stop fabric is arranged in a hole, carrying out shield receivingand welding the forward-moving roller while receiving; moving the whole shield machine forwards, cutting a U-shaped groove plate at a shield connecting bridge off, paving the shield forward-moving guide rail, installing the counter-force device, and enabling the shield to move continuously forwards under the actions of the counter-force device and an oil cylinder; cutting the forward-moving roller off in the process of moving the shield to an originated base forwards, arranging the oil cylinder to the originated base and the side wall of an originated wall, starting the oil cylinder so that the shield body and the originated base translate together along the articulation part of the connecting bridge and the shield body and subsequent associated equipment are in the same straight line, and carrying out second originating. The roller guide rail station-passing construction method has the advantages of simple process, short construction peroid, low cost, risk controllability and the like and has favorable economic and social benefits and wide application range.

Description

technical field [0001] The invention relates to the technical field of tunnel shield construction, in particular to a construction method for a complete shield machine roller guide rail over station. Background technique [0002] With the continuous construction of urban infrastructure, subway rail transit is showing a trend of rapid development, and shield machines are more and more widely used due to their advantages of safety, speed, mechanization and automation. In the construction of urban subways, in order to facilitate the travel of passengers in the future, the station distance is generally short and the number of stations is relatively large. Moreover, most of the current domestic construction methods are to construct the subway stations first, and then construct the tunnel part. In order to ensure the continuity of construction and Generally, each bidding section contains several stations. In this case, after the shield machine is constructed in one section, it mus...
