Guangzhou's three subway new lines of civil construction exceed 75%

Recently, the south of the Guangzhou Metro Line VIIIII to the south of the city of Shenzhen to Shenjing (hereinafter referred to as the depths) achieved dual -line penetration, and the main structure of Dashadong Station was successfully capped. So far, 79%of the Civil Construction of the entire line was completed. Today, the Guangzhou Metro has announced the latest progress as of the end of July at the end of July. There are three lines that have completed more than 75%of the civil construction: Line 11, Phase III, and Line 3.

Near 80 % of the Titan Building on Line 7

It is reported that the left -line tunnel on the Great Division is about 2623 meters long and the right tunnel is 2608 meters. Due to the complexity of geological conditions along the interval tunnel, the geology is uneven, it is easy to cause problems such as tool wear and excessive shield correction. At the same time, the tunnel also needs to wear a number of pearl river tributaries. The water content of the stratum is high. When the shield machine crosses the river bed shield construction, it is prone to risks and other risks.

In response to the characteristics of shield excavation geology and large construction risks, the Guangzhou Metro and construction unit China Railway Guangzhou Engineering Bureau has repeatedly organized experts to analyze and demonstrate the major dangerous sources and risk points. A smart pulp system is added to effectively draw the sprayed slurry to reduce the waste of the construction period to ensure that the shield is excavated continuously.

The reporter learned that Dasha East Station is the only underground four -story station on the second phase of Metro Line 7, and has transferred to Dashadong Station with existing Line 5. The station is located in the old city of Huangpu District, with the largest foundation pit excavation depth of 39 meters. This is also the deepest foundation pit project in the entire line.

In response to the technical difficulties of the deep -founded pit excavation, the Guangzhou Metro and the construction unit China Railway Tenth to make targeted reinforcement to the suspected defect before excavation to ensure the stability of the enclosure structure. The stratum strata have high rocks and low excavation work. In order to improve the construction efficiency, the subway builders are looking for construction machinery with high rock -breaking efficiency. Finally, different rock breaking equipment such as "eagle hook machines" and "woodpeckers" are eventually put in different stages. Elected excavation equipment with the highest efficiency.

Up to now, the second phase of Line 7 (Southwest University of the University Town): 79%of the Citizenship has been completed. Among the 11 stations, 5 were capped and started mechanical and electrical construction, and 6 of the civil construction were carried out; 6 of the 11 areas have been connected; 5 and the entry -exit section lines are carried out for civil construction.

Other lines under construction are updated

Line 3 Dongyan section (Panyu Plaza-Sea Piece): 75%of the Civil Construction Project has completed a total of 75%. Among the four stations, two have been capped, and the remaining two are carried out in civil construction; two of the four areas have been connected, and the remaining two and the entry and exit lines are performed for civil construction. The construction of civil construction in Guangzhou New Town.

East Yan section 5 (Wenchong-Huangpu Passenger Transport Port): 69%of the civil construction projects. Among the 6 stations on the entire line, three have been capped and started mechanical and electrical construction, and the remaining 3 of them are carried out in civil construction. Among the 6 areas, two have been connected, and 4 and the entry and exit lines are carried out for civil construction. Shuanggang parking lot construction.

Line 10 (Xiyi-Shipai Bridge): 49%of the Civil Construction Project has been completed. Among the 14 stations, 4 were capped, nine were carried out in civil construction, and the remaining 1 of the remaining 1 was prepared; 3 of the 14 sections had been connected, 5 and the entry -exit section lines were carried out for civil construction, and the remaining preparations were carried out. The construction of the vehicle section of the Guangsteel New Town is carried out.

Line 11 (Railway Station-Pazhou-Railway Station): A total of 84%of the civil construction project was completed. Among the 32 stations, one is preparing for the preliminary preparations, 2 has been opened, and 14 has been capped, and the remaining 15 are under construction. Among the 32 areas, 1 has been built and opened, 16 has been opened, and 13 are carried out. For civil construction, the remaining two are prepared before construction; the Chisha vehicle section and the entry and exit section are carried out for civil construction. The two stations began to renovate and install mechanical and electrical installation.

Line 12 (Yifenggang-University Town South): 47%of the civil engineering projects have been completed. Among the 25 stations, 7 main structures were capped, 17 were under construction, and 1 were prepared in the first stage; 3 of the 24 interval penetrated, and the construction of civil construction was carried out. The remaining 8 were prepared before construction. The section and entry and exit section of the head, the South parking lot of the university town and the entrance line for civil construction.

Phase II (Chaoyang-Fish Bead): Cumulative 53%of the civil engineering projects. Among the 23 stations, 5 are capped, 17 are planned for civil construction, and 1 stations are prepared for preliminary preparations. Among the 23 areas, 6 areas and the entry and exit lines of the Phoenix parking lot have been connected. Preparation for preliminary preparation. Fish Parking Lot, Phoenix Parking Lot and Cover for civil construction.

Phase II (Jiahe Wanggang-Guangzhou Railway Station): 36%of the civil engineering projects. Among the eight stations, the four main structures were capped, two were construction in civil construction, and the remaining two were prepared for preliminary preparations. Among the 8 sections, 2 were connected, 4 were carried out in civil construction, and the remaining 2 were preparations.

The rear section of Line 18 (村--Guangzhou East Station): The cumulative 12%of the civil engineering project is completed. The construction of civil construction in the east to the village of Guangzhou.

Line 22 (Chen Tougang-Fangcun): A total of 23%of the civil construction project was completed. All 4 stations were carried out in civil construction; one of the four sections was carried out in civil construction, and the remaining 3 were prepared before 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.)
