For the first time, the construction of mechanical method was adopted, and the civil construction project of Guangzhou Metro Line 3 was completed 76%

Recently, the construction of the East extension of the Guangzhou Metro Line 3 was transmitted again: Panyu Passenger Station to the west section of the west of Guangzhou (hereinafter referred to as Fanguang) No. 4 liaison passage successfully runs through. project. As of now, the east extension section of Line 3 (Panyu Plaza-Sea-side) has completed a total of 76%.

The risk of traditional work and law is low, and the construction of mechanical laws is used for the first time

The full length of the Fanguang area is 2.8 kilometers, of which the No. 4 liaison passage is located below the Asian Games Avenue. In the past, the distance between the contact channels was generally short. Most of the mining method was used to excavate and carried out traditional artificial operations, but the construction control was difficult. Considering that the distance between the No. 4 contact channel of the Fanguang Division is relatively long and the risk of the mining method is low, the Guangzhou Metro adopts the mechanical method for contact channel construction for the first time. Construction has effectively improved security and economics.

In the absence of the case of project cases, Guangzhou Metro and construction unit Guangzhou Construction and Supervision Unit Guangzhou Metro Supervision carried out multiple rounds of technical research from the preliminary preparation of the project to the construction process, which provided a strong guarantee for the connection between the contact channel to provide a strong guarantee Essence The Guangzhou Metro stated that the smooth penetration of the Liaison Channel on the No. 4 of Fanguang Division has important guiding significance and reference value for the standardized construction in the surrounding areas and the national mechanical law connection channel.

Put through Heyong and add interval tunnels to penetrate

In addition to the contact channel, the shield machine responsible for the excavation of the section of the Guangzhou New Town to Jinguang Avenue (hereinafter referred to as the Golden Golden Division) also successfully broke the cave door and entered the receiving steel sleeve recently, marking the dual line of the tunnel of the interval.

The length of the Guangzhou -Jin Division is about 1.48 kilometers. The geological conditions are complex, the construction of the buildings along the line, the underground pipeline dense, the ground environment is sensitive, and the shield machine starts from Jinguang Avenue Station. The pipeline finally arrived at the west station of Guangzhou New City.

Faced with many difficulties in construction, the subway builders wearing various types of sensitive construction buildings under the shield machine to prepare special construction plans before the shield machine, and strictly conjugate the operators. Poor, timely adjust the excavation parameters, and arrange personnel to inspect the ground and rivers in 24 hours to ensure that it is foolproof.

As of now, the east extension section of Line 3 (Panyu Plaza-Sea-side) has completed a total of 76%. Of the four stations, 3 were capped, and one of the remaining one was carried out for civil construction; 3 of the four sections had been connected, and the remaining one and the entry and exit lines were performed for civil construction. The construction of civil construction in Guangzhou New Town. The rail engineering is under construction.

(Note: The name of the above stations is only the tentative of the project, and the standard station name shall be based on the approval of the municipal government.)
