500KV high voltage line under the cast in place beam safety construction plan

The general construction BAI scheme is aimed at the general construction structure (not complex and specific).

DAO on-site construction needs to be organized and arranged!

The special construction plan is for the complex process and specific parts (such as cast-in-place box girder with a span of 160m), which is the construction arrangement and configuration.

Safety special construction plan: refers to the safety construction arrangement and configuration for the production parts with potential safety hazards on the site (such as high-voltage offline construction, deep foundation pit construction, etc.).

Safety measures and special construction plans.

Guilong Avenue (Guiyang Section) Road Project.

Qinqi River Bridge, cross-construction road and bridge cast-in-place box girder construction plan.

1. Basis for compilation.

1) "Guilong Avenue (Guiyang Section) Road Engineering Section 3 Contract Section Construction Drawing Design";

2) "Bidding Documents";

3) "Technical Code for Construction of Highway Bridges and Culverts" (JTGTF50-2011);

4) "Highway Engineering Quality Inspection and Evaluation Standards" (JTG F80 1-2004);

5) Code for Acceptance of Construction Quality of Concrete Structure Engineering (GB50204-2002);

6) Relevant requirements of the owner and the superintendent's office.

Second, the general situation of the project.

Qinqihe Bridge is located on the main line of Guilong Avenue, divided into left and right lines, the left line starting mileage: zk19 + 048, the end mileage: zk19 + 277, the right line bridge starting mileage:

YK19+053, end mileage: YK+282, the total length of the bridge is 229m, the standard width of a single line is, and the cross slope. The superstructure of Qinqihe Bridge adopts (5*25+45*2m) 2 multi-span prestressed widening continuous box girders, of which the standard 25m span continuous box girder is made of C50 concrete, the height of the box girder, the cross-section continuous beam is used, the end beam is high m, and the middle beam is highThe cross-section of the beam body adopts a single-box multi-chamber cross-section of the oblique web, the width of the main line bridge wing plate is 2m, the width of the web of the standard section is 50cm, the thickness of the roof is 22cm, and the thickness of the bottom plate is 20cm.

The pier adopts a T-shaped pier, the cross-section is octagonal, the widest part of the main line pier is, the pier thickness is and two kinds, the pier top is provided with a T-shaped cap beam, and the pier bottom is connected to 2m (high cushion cap, the foundation adopts pile foundation, and the abutment adopts gravity abutment.

The bridge is located at the main line of Guilong Avenue and the node of the construction road, the bridge is a span overpass, the left and right lines of the bridge are arranged, and the mileage of the starting point of the left line: three 3 (four) 7 in the concrete construction in the box vibrating and dismantling the mold to be carried out from top to bottom, and abide by the principle of first support and then demolition, and then dismantling after support. Remove the corners with special care to prevent.

According to the construction needs, erect protective scaffolding. You can consult the power supply company responsible for the operation of the line, and he will introduce you to a professional construction team, which is generally charged according to the area and time of erection protection.
